Problems solved by technology

The situation encountered by the car on the road is quite complicated. The size of the input shaft of the current drive axle assembly is relatively small, the bearing load is small, and there are high requirements for manufacturing precision and craftsmanship. The anti-seepage and oil-proof process of the body interface is extremely demanding, the manufacturing cost is high, and there is no corner structure, so for models with high torque and high strength requirements, this structure has certain hidden dangers

Abstract

The invention belongs to the technical field of automobile driving accessories, and provides an input bending angle structure of a driving axle assembly. The input bending angle structure comprises an inner ball cage, an outer ball cage, an input shaft, an output shaft and a transmission shaft, wherein the inner ball cage and the outer ball cage are connected with each other through the transmission shaft; the output shaft is connected to the outer ball cage; the input shaft is connected to the inner ball cage; a bending angle is formed along the connecting direction of the output shaft and a gear in an external gear-box; the angle control range of the bending angle is 14.3-22.5 degrees; and relative moving displacement is controlled between -18.3 millimeters and +14.7 millimeters. The invention has the advantages that the load carrying capability is improved through the bending angle, and the input bending angle structure is suitable for automobile types of high loads and high torques; moreover, the lower part of a fixed connecting frame is taken as a bearing base, so that a bearing in an installation hole is protected, and the input shaft can be rotated conveniently; and meanwhile, the fixed connecting frame can be used for locking the input end, so that shake is reduced, and the rotating stability of the input shaft is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile drive accessories, and relates to an input bending angle structure of a drive axle assembly. Background technique [0002] In order to transmit the power of the car, the drive axle of the car will be used. At present, the ball cage drive axle is the most used. The transmission work angle is large and the efficiency is high. The situation encountered by the car on the road is quite complicated. The size of the input shaft of the current drive axle assembly is relatively small, the bearing load is small, and there are high requirements for manufacturing precision and craftsmanship. The anti-seepage and oil-proof process of the body interface is extremely demanding, the manufacturing cost is high, and there is no corner structure, so for models with high torque and high strength requirements, this structure has certain hidden dangers. Contents of the invention [0003] The technical problem to...
