Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a multi-link high-load rear-drive axle. Background Art

[0002] The rear axle refers to the rear drive shaft component of the vehicle's power transmission. It consists of two half-bridges, which can implement half-bridge differential movement. At the same time, it is also a device used to support the wheels and connect the rear wheels. If it is a front-axle driven vehicle, then the rear axle is just a follower axle and only plays a bearing role. If the front axle is not a drive axle, then the rear axle is a drive axle. In this case, in addition to the bearing function, it also plays the role of driving, deceleration and differential. If it is a four-wheel drive, there is generally a transfer case in front of the rear axle. The rear axle is divided into an integral axle and a half-bridge. The integral axle is equipped with a non-independent suspension, such as a leaf spring suspension, and the half-bridge is equipped with an independent suspension, such as a McPherson suspension.

[0003] In the prior art, the load-bearing capacity of the rear-wheel drive axle is insufficient, resulting in an increase in the bearing load during driving of the vehicle, which reduces the service life of the rear-wheel drive axle and directly affects the service life of the vehicle. In view of this, we propose a multi-link high-load rear-wheel drive axle to solve the problems raised in the background technology. Utility Model Content
