We'll assume you're ok with this, but you can opt-out if you wish. Buy leaf springs for trucks, trailers, and cars at TruckSpring.com. For example, a 3.78 ratio means there are 3.78 spikes on the ring gear for every 1 spike on the pinion gear. Even when the suspension is not independent, split axles permit the use of a differential, allowing the left and right drive wheels to be driven at different speeds as the automobile turns, improving traction and extending tire life. Minimizes the chance of axle moving causing damage to other components and losing control should rubber insert fail. Some dump trucks and trailers may be configured with a lift axle (also known as an airlift axle or drop axle), which may be mechanically raised or lowered. NEW -- Torque Rod End Bushing with Integral Keeper Bar 5 ton Rubber Torque Rod End Bushing with Integral Keeper Bar. In a live-axle suspension system, the axles serve to transmit driving torque to the wheel, as well as to maintain the position of the wheels relative to each other and to the vehicle body. However, other go-karts have two rear drive wheels too. There are also 6X2 tandem axle configurations in which power is only supplied to one rear axle in an attempt to reduce vehicle weight and increase fuel economy. Lift axles were in use in the early 1940s. In the latter case, a bearing or bushing sits inside a central hole in the wheel to allow the wheel or gear to rotate around the axle.

On cars and trucks, several senses of the word axle occur in casual usage, referring to the shaft itself, its housing, or simply any transverse pair of wheels. Any front wheel drive car (or 4×4) will have a CV axle nut. One of the early manufacturers was Zetterbergs, located in ÃstervÃ¥la, Sweden. A tag axle is a dead axle situated behind a drive axle. All rights reserved. Also available are complete line of suspension accessories and Mack and Hendrickson Suspension Parts. Instead, the bearing hubs (at the outer ends of the axle) carry the truck’s weight. Therefore, you will want to assess the axle ratio to provides a strong balance while maintaining reasonable fuel efficiency rates. The main difference between the full- and semi-floating axle setups is the number of bearings. Modern passenger cars have split drive axles. This website uses cookies to improve your experience and to personalise content and adverts, to provide social media features and to analyse traffic. The liftable tandem drive axle was invented in 1957 by the Finnish truck manufacturer Vanajan Autotehdas, a company sharing history with Sisu Auto. For the purposes of this discussion, I will be using hub nut/spindle nut/axle nut/axle drive nut/ to mean the same thing. Straight axles are used on trains (that is, locomotives and railway wagons), for the rear axles of commercial trucks, and on heavy duty off-road vehicles. A common practice in most maintenance facilities is to use a impact wrench to tighten U-Bolts. This category contains hundreds of Traxxas Rustler parts like bodies, tires, wheels, batteries, and of course performance hop-up parts. Therefore, smaller tires will increase the speeds at which the truck may travel at. An even broader (somewhat figurative) sense of the word refers to every pair of parallel wheels on opposite sides of a vehicle, regardless of their mechanical connection to each other and to the vehicle frame or body. This setup allows the axle shaft to be the means of propulsion, and also support the weight of the vehicle. A dead axle located immediately in front of a drive axle is called a pusher axle. The axle shafts (usually constant-velocity type) then transmit driving torque to the wheels. They may be attached to the vehicle frame or body, or integral in a transaxle.

Many trucks and trailers use dead axles for strictly load-bearing purposes. The GM 8.875" (often rounded to 8.9") 12 Bolt axle is available in passenger car (GM 12P) and truck (GM 12T) rear axle configurations and features an 8.875" ring gear and 30 spline semi floating axle shafts. You also have the option to opt-out of these cookies. A tandem axle is a group of two or more axles situated close together. They "float" inside an assembly that carries the vehicle's weight. Several manufacturers offer computer-controlled airlift, so that the dead axles are automatically lowered when the main axle reaches its weight limit. Each half axle connects to the wheel by use of a constant velocity (CV) joint which allows the wheel assembly to move freely vertically as well as to pivot when making turns. Be Finicky About Wheel Bearings. This means the driveshaft must turn 3.78 times to turn the axle wheels one entire cycle. Using a socket wrench, you will tighten the nuts.

In some designs the wheels on a lazy axle only come into contact with ground when the load is significant, thus saving unnecessary tire wear. The full-floating design is typically used in most 3/4- and 1-ton light trucks, medium duty trucks and heavy-duty trucks, as well as most agricultural applications, such as large tractors and self-propelled agricultural machinery. The axles in this system must also bear the weight of the vehicle plus any cargo. The number of rear axles will usually determine what axle truck it is. If the route(s) your truck(s) take to transport goods have steep slopes then a higher ratio is required. 2.6 rear end gear ratio 1946 Chevy Truck Parts | Chevs of the 40s has the most complete inventory of 1946 Chevy Truck restoration parts and 1946 Chevy Truck street rod parts. Torque range represented in lb-ft is a detriment of the rate at which the truck can pull a load from a stop. Semi trailers usually have a tandem axle at the rear. In other types of suspension systems, the axles serve only to transmit driving torque to the wheels; the position and angle of the wheel hubs is an independent function of the suspension system. Full-floating axle shafts are retained by a flange bolted to the hub, while the hub and bearings are retained on the spindle by a large nut. Then to hide the (unsightly) large center retaining nut, install a 15/16" stainless steel lug nut cover. Majority of semi-trucks are equipped with one front steer axle and two rear axles combined as a tandem axle. With four fewer gears than the Chevy and the Ford, the Ram spends less time shifting and more time in the boost. The main manufacturers of drive axles for semi-trucks are DANA, Hendrickson, Meritor, Mack, PACCAR, and Detroit Do not reuse auto or truck Leaf Spring U bolts • Used U-bolts will have rusted and damaged threads from the previous installation. Strictly speaking, a shaft which rotates with the wheel, being either bolted or splined in fixed relation to it, is called an axle or axle shaft. Engine 425 In rear-wheel drive cars and trucks, the engine turns a driveshaft (also called a propellor shaft or tailshaft) which transmits rotational force to a drive axle at the rear of the vehicle. The semi-truck axles are also called the drive axles. We carry every version of the Traxxas Slash along with the complete line of replacement parts and performance upgrade parts. Axles are typically made from SAE grade 41xx steel or SAE grade 10xx steel. These systems still have differentials, but will not have attached axle housing tubes.

Like a full floating axle system, the drive shafts in a front-wheel drive independent suspension system do not support any vehicle weight. Some simple vehicle designs, such as leisure go-karts, may have a single driven wheel where the drive axle is a split axle with only one of the two shafts driven by the engine, or else have both wheels connected to one shaft without a differential (kart racing). A dead axle, also called a lazy axle, is not part of the drivetrain, but is instead free-rotating. Later they acquired a plastic extrusion facility. Their brand was Zeta-lyften. The overall assembly can carry more weight than a semi-floating or non-floating axle assembly, because the hubs have two bearings riding on a fixed spindle. An axle that is driven by the engine or prime mover is called a drive axle. In split-axle designs, the wheel on each side is attached to a separate shaft. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website.

The dead axles can still be lifted by the press of a button if needed, for better maneuverability. Or, to hide the three bolts and retaining nut, install a chrome-plated universal custom automotive horn button (center cap). Modern front-wheel drive cars typically combine the transmission (gearbox and differential) and front axle into a single unit called a transaxle. A two rear-axle truck is commonly paired with a tandem axle trailer which can be identified with two pairs of wheels near the end and a kingpin at the front that connects to the hitch. In fact, only one wheel of that axle is actually moving the truck and trailer down the road. This website uses cookies to improve your experience while you navigate through the website. On-highway trucks will generally travel at significant speeds for long durations with consistent load weights. We stock a complete line of OEM quality replacement leaf springs for all vehicles. A previously torqued U-bolt will suffer from distorted threads from the engagement of the deep nut. Step 1: Remove The Axle Nut from the Center of the wheel. This very loose definition of "axle" is often used in assessing toll roads or vehicle taxes, and is taken as a rough proxy for the overall weight-bearing capacity of a vehicle, and its potential for causing wear or damage to roadway surfaces. Leaf Spring U-Bolts Are Available From Grade 5 U-Bolts To Grade 8 U-Bolts. The axis of rotation fixed by the axle is common to both wheels. Great price for added security. A full-floating axle can be identified by a protruding hub to which the axle shaft flange is bolted. They must be able to withstand the weight of the commercial vehicle and any added cargo in the trailer. Thus, transverse pairs of wheels in an independent suspension may be called an axle in some contexts. In some designs, this allows independent suspension of the left and right wheels, and therefore a smoother ride. A straight axle is a single rigid shaft connecting a wheel on the left side of the vehicle to a wheel on the right side.

[3]the front drive axle is providing the force to drive the truck. Additionally the bend type must also be specified; either round, semi-round or square. The axle ratio represents the relationship between the number of spikes on the ring gear of the tandem axles to the number of spikes on the pinion gear on the driveshaft. However, there has been debate whether 6×2 drive axles are adept to heavy-duty applications. For example, a truck with a grade ability of 10% at 80mph can maintain that level of speed for that gradeability level. These cookies do not store any personal information. Copyright © 2018 TruckFreighter.com. The semi-floating design is found under most 1/2-ton and lighter trucks and SUVs and rear-wheel-drive passenger cars, usually being smaller or less expensive models. By 1971, Sam and his sons developed GreatNeck / OEM Tools into a major company in the hand tool industry by purchasing Buck Bros., a chisel company, based in Massachusetts, and Mayes Brothers, a company from Tennessee in the level production business. The smaller the tire circumference, the drive axle operates as if it was classified at a lower ratio compared to if the tire had a larger circumference. SAE grade 41xx steel is commonly known as "chrome-molybdenum steel" (or "chrome-moly") while SAE grade 10xx steel is known as "carbon steel".

There are a few exceptions, such as many Land-Rover vehicles and in American stock car racing since the early 1960s. Dead axles are also found on semi trailers, farm equipment, and certain heavy construction machinery serving the same function. In some situations removal of pressure from the additional axle is necessary for the vehicle to complete a turn at all.[4]. The following table outlines some of the tandem drive axles available on the market: The aforementioned provides a general introduction to semi truck axle ratios and their relationship to a tractor’s performance. Please note, you must always keep the u-bolt nut tight at all times and re-torque the u-bolt within 500 miles after being replaced. Anywhere from 450-525 will provide excellent horsepower to haul less-than-truckload and most full-truck-load freight. The drive axles impact a truck’s ability to pull heavy loads, the speeds it can travel at, the overall fuel usage, and conclusively the company’s bottom line. When not needed, the axle is lifted off the ground to save wear on the tires and axle, and to increase traction in the remaining wheels. This is typical of the independent suspensions found on most newer cars and SUVs, and on the front of many light trucks. The rear axle of a front-wheel drive car is usually a dead axle. We recommend using a torque wrench when installing U-Bolts. Best Semi Truck Axle Ratio. Team Integy's R/C Cars! Speed, Grade-ability, Load type and weight, Towing, Aerodynamics, Tire Size, Torque Converter are all factors to take into consideration when assessing which axle ratio will best fit your fleet whether that consists of only a few to a large number of trucks. Thus the only stress it must endure is torque (not lateral bending force). Because of the above, FF axle shafts are not subject to bending loads like semi float (SF) axles are and can therefore be made of harder materials making them capable of carrying greater torque loads An axle or axletree is a central shaft for a rotating wheel or gear. With a socket, loosen and remove the axle nut from the center of the wheel. whether 6×2 drive axles are adept to heavy-duty applications. Necessary cookies are absolutely essential for the website to function properly.
