The invention provides a spline type universal joint. The spline type universal joint comprises an outstar wheel and an instar wheel, wherein a cavity for containing the instar wheel is formed in theoutstar wheel, a circle of internal splines which are distributed in parallel are arranged on the inner wall of the cavity, internal spline grooves are formed between adjacent internal splines, and the internal spline grooves are straight long grooves; external splines which extend into the internal spline grooves are arranged on the outer surface of the instar wheel, external spline grooves are formed between adjacent external splines, the surfaces, which axially extend along the instar wheel, of the external splines are cambered surfaces, and the width of the external splines in the circumferential direction of the instar wheel is gradually reduced from the middle of the external splines to both ends of the external splines. The spline type universal joint has the advantage of easiness in production and assembly, and a steel ball and a retainer in a traditional universal joint are omitted.
Description
technical field [0001] The invention relates to a universal joint, in particular to a splined universal joint. Background technique [0002] In the transmission system of a car, the universal joint is an essential component in order to transmit torque when there is an angle between the input end and the output end. The universal joint is the universal joint, which is a component that realizes variable-angle power transmission. It is used to change the position of the transmission axis direction. It is the "joint" part of the universal transmission device of the automobile drive system. The combination of universal joint and transmission shaft is called universal joint transmission. On vehicles with front-engine rear-wheel drive, the universal joint transmission device is installed between the output shaft of the transmission and the input shaft of the drive axle final drive; while the vehicle with front-engine front-wheel drive omits the drive shaft, the universal joint is ...
