Abstract
The utility model discloses a disk brake rear axle which includes a rear axle pipe, a left and a right half shafts which are installed in the rear axle pipe and a differential assembly which is installed on the rear axle pipe. The rear axle pipe consists of a left rear axle pipe and a right rear axle pipe. The left and the right rear axle pipes are connected with the differential assembly in a way of fixing through a rear bearing chamber. The left and the right rear axle pipes are connected with the left and the right half shafts through a bearing which is arranged in a shaft sleeve. The left and the right half shafts are connected with a collar rim through a connecting flange and are fixed on the collar rim through a bolt. The internal side of the collar rim is equipped with a disk brake plate. A brake pump is installed on a junction part of the internal side of the disk brake plate and the half shafts. The disk brake rear axle can also be applied to other vehicles and has the advantages of simple structure, reasonable arrangement and loading and good braking effect. Sideslip phenomena can not happen to the vehicles during the braking. And the disk brake rear axle is safer and more reliable.
Description
