Abstract

The invention relates to a drive axle assembly with a main speed reducer parking structure. The drive axle assembly comprises a drive axle shell, a half shaft connected with the output end of a differential mechanism in the drive axle shell, a half shaft sleeve arranged on the outer side of the half shaft in a sleeving mode, a hub installed on the half shaft sleeve, a service braking mechanism which is mounted on one side of the hub, and a parking braking mechanism which is mounted on a main speed reducer shell. According to the equipment, the service braking mechanism and the parking braking mechanism are separately arranged, the service braking mechanism on the wheel side is formed by combining a brake disc and calipers, and the overall structure is simple; the parking braking mechanism is designed on a flange for transmission of the main speed reducer, a drum brake is adopted, the diameter of the parking brake is small, the mechanical braking effect is reliable, the structure is simple, the parking function can be achieved through a single parking brake, and the development cost is reduced.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a drive axle assembly with a parking structure of a final reducer. Background technique [0002] The driving brake is generally called the foot brake, which is the function of slowing down or stopping the vehicle during driving. During operation, the intensity of the brakes is mainly controlled by depressing the intensity of the brake pedal, so that the car can slow down or stop within the shortest distance. The parking brake is generally called the hand brake, which is to give the car a resistance when parking, so that the car does not slip. [0003] At present, the service brake and parking brake of light trucks on the market are generally designed and arranged on the wheel edge, and share a brake and a brake drum. When the car is driving and the brake pedal is stepped on, the sub-cylinder of the brake works to pull the brake shoe and the brake drum to perform the driving brake; aft...
