Rear axle, is refers to the vehicle power transmission after the drive shaft component. It is composed of two half Bridges and can implement half bridge differential motion. It is also used to support the wheels and connect the rear wheels. If the vehicle is driven by the front bridge, then the rear bridge is just a follow-up bridge, which only plays a bearing role. If the front axle is not a drive axle, then the rear axle is a drive axle. At this time, in addition to the bearing role, it also plays the role of driving and deceleration and differential speed. The rear bridge is divided into integral bridge and half bridge. The whole bridge is equipped with non-independent suspension, such as plate spring suspension, and the half bridge is equipped with independent suspension, such as McPherson suspension.

A back bridge is the bridge behind a car:

If the bridge is not a drive axle, then the rear axle is a drive axle. At this time, in addition to the load bearing role, it also plays the role of driving and deceleration as well as differential speed.

Front axle rear axle is refers to the front and rear axle parts, front axle including shock absorber spring, steering gear, balance shaft, etc., rear axle also includes drive shaft, transmission gear, etc. The rear of multi-axle truck is also divided into driving rear axle and non-driving rear axle. Non-driving rear axle is the part that does not belong to the driving wheel and is not connected with the drive shaft. Generally, it is the heavy truck with more than 3 axes and the traction head.

Classification of rear axle:

According to the different suspension of the bridge, divided into integral type and open type.

integral

Integral bridge with non - independent suspension, such as spring suspension.

Broken open

Split type with independent suspension, such as McPherson suspension.

Overview of rear axle center

As for the rear axle center of the big drum is in the rear axle drive axle is only under the circumstances, because it is put inside the reduction gear and differential speed mechanism, so there should be a big drum, the rear axle is with the general bridge is not.

Axle classification

According to the different functions of the axle, the axle can be divided into drive axle, steering axle, supporting axle and steering axle.
