- The total rear weight of the vehicle causing both bending and sharing action.
- side thrust on the wheels when cornering, which imposes bending load and an ending trust or a pull.
- Driving torque.
|Bending and shearing of the rear axle|
Therefore, it needs to be of a large size for the same torque output than any other type. The inner end of the axle is supported by the differential side gear. It thus carries the entire weight of the vehicle by the axle housing.
The outer end has to support the weight of the car and take end thrust. The inner end of the axle is splined to the differential side gear. The outer end is flanged So that the wheel can be directly bolted to it. In some designs, the hub of the wheel is keyed to the outer end of the axle. The vehicle load is transmitted to the axle through the casing and the bearing, which causes the bending or shearing of the axle.
The semi-floating axle is the simplest and cheapest of all other types and widely used on cars. A semi-floating common on the rear of most 4x4s. It consists of axle shaft on splined on the inner it mates to the differential and wheel the wheel studs mount at . This assembly mates to of the axle housing some arrangement. The axle shaft rides on roller or out at of the axle housing.
The axle shaft semi-floating assembly serves . First, it attaches to the wheel and to support of the vehicle and its . Second, the axle shaft transmit the from the differential the wheel.
