Rear axle assembly pdf
Not rear axle assembly pdf be confused with Axl or Axel. Railroad car wheels are affixed to a straight axle, such that both wheels rotate in unison. An axle is a central shaft for a rotating wheel or gear.
On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle, with the wheels rotating 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. 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. Thus, transverse pairs of wheels in an independent suspension may be called an axle in some contexts.
Axles are an integral component of most practical wheeled vehicles. 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. The axles in this system must also bear the weight of the vehicle plus any cargo. This is typical of the independent suspensions found on most newer cars and SUVs, and on the front of many light trucks.
These systems still have differentials, but will not have attached axle housing tubes. 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. The axis of rotation fixed by the axle is common to both wheels. Such a design can keep the wheel positions steady under heavy stress, and can therefore support heavy loads. In split-axle designs, the wheel on each side is attached to a separate shaft.
Modern passenger cars have split drive axles. In some designs, this allows independent suspension of the left and right wheels, and therefore a smoother ride. 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. A tandem axle is a group of two or more axles situated close together.
Truck designs use such a configuration to provide a greater weight capacity than a single axle. Semi trailers usually have a tandem axle at the rear. Axles are typically made from SAE grade 41xx steel or SAE grade 10xx steel. SAE grade 10xx steel is known as “carbon steel”. Splines on a front drive axle. An axle that is driven by the engine or prime mover is called a drive axle.
However, other go-karts have two rear drive wheels too. A dead axle, also called a lazy axle, is not part of the drivetrain, but is instead free-rotating. The rear axle of a front-wheel drive car is usually a dead axle. Many trucks and trailers use dead axles for strictly load-bearing purposes. A dead axle located immediately in front of a drive axle is called a pusher axle.
A tag axle is a dead axle situated behind a drive axle. The axle is lowered to increase the weight capacity, or to distribute the weight of the cargo over more wheels, for example to cross a weight restricted bridge. 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. Several manufacturers offer computer-controlled airlift, so that the dead axles are automatically lowered when the main axle reaches its weight limit.
The dead axles can still be lifted by the press of a button if needed, for better maneuverability. Lift axles were in use in the early 1940s. Initially, the axle was lifted by a mechanical device. Soon hydraulics replaced the mechanical lift system. One of the early manufacturers was Zetterbergs, located in Östervåla, Sweden.
