Abstract

The invention relates to a connecting structure of a constant velocity universal joint and a wheel hub and an automobile. The connecting structure comprises the wheel hub, a steering knuckle, the constant velocity universal joint, bearings, bearing bolts, locking nuts and a self-locking nut, wherein a central inner cavity of the wheel hub extends from a wheel to the direction of the locking nuts, the central inner cavity sequentially comprises a first cylindrical inner cavity, a second cylindrical inner cavity, a third cylindrical inner cavity and a fourth cylindrical inner cavity; radii of the second cylindrical inner cavity and the fourth cylindrical inner cavity are identical and are respectively greater than the radius of the third cylindrical inner cavity; a plurality of sharp toothed protrusions are axially arranged on the side surface of the outer end of the constant velocity universal joint; the distance between tips of the sharp toothed protrusions and a central line of the outer end of the constant velocity universal joint is greater than the radius of the third cylindrical inner cavity; the hardness of the outer end of the constant velocity universal joint is greater than that of the wheel hub. According to the technical scheme, by means of a crimping structure of the outer end of the constant velocity universal joint and the inner cavity of the wheel hub, a connecting clearance between the wheel hub and the constant velocity universal joint is completely eliminated, the fluctuation of a transmission torque is eliminated, and transmission vibration and wheel vibration are reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile hubs, in particular to a connection structure between a constant velocity universal joint and a hub and an automobile. Background technique [0002] The transmission device that drives the wheels is located at the end of the car's drive train, and its function is to transmit torque from the side gears of the differential to the drive wheels. The structure type of the driving wheel transmission is closely related to the structure type of the drive axle. In the disconnected drive axle and the steering drive axle, the drive wheel transmission device includes a half shaft and a universal joint transmission device, and most of them use constant velocity universal joints. Festival. [0003] A universal joint in which the angular velocity of the main and driven shafts is still equal when the angle between the two axes changes is called a constant velocity universal joint. The common structures in en...
