Connecting device for transmission shaft and input shaft

Abstract

The invention discloses a connecting device for a transmission shaft and an input shaft. The connecting device comprises a first flange, a second flange, pin bodies and a limiting ring. The first flange is in transmission connection with the transmission shaft. Multiple first through grooves are formed in the outer circumference of the first flange. The second flange is in transmission connectionwith the input shaft, and multiple second through grooves are formed in the outer circumference of the second flange. The second through grooves are in one-to-one correspondence with the first throughgrooves. One end of each pin body is located in the corresponding first through groove, and the other end of each pin body is located in the corresponding second through groove. An annular limiting groove is formed in the inner wall of the limiting ring. The limiting ring is arranged on the first flange and the second flange in a sleeving manner. One end face of the first flange and one end faceof the second flange abut against the two side walls of the annular limiting groove correspondingly. By means of the connecting device, the air resistance formed in the transmission process can be reduced; transmission efficiency can be improved; and the air noise can be reduced.

Description

Technical field [0001] The invention relates to the technical field of automobile transmission, in particular to a connecting device of a transmission shaft and an input shaft. Background technique [0002] In order to achieve power transmission, the vehicle transmission shaft must be connected with the rear axle input shaft. [0003] At present, the connection structure of the drive shaft and the input shaft of the rear axle on the automobile is connected by flange and bolt and nut components, and 4 sets of bolt and nut components are used to connect the output flange of the drive shaft and the flange on the input shaft of the rear axle. , Realize power transmission. [0004] The connection structure of the drive shaft and the input shaft of the rear axle used in the automobile is connected by flange and bolt and nut components. Because the flange and bolt and nut components need to be connected by 4 sets of bolts and nuts, the structure is complicated, the production process is di...

Problems solved by technology

[0004] The connection structure between the transmission shaft and the input shaft of the rear axle used in automobiles is connected by flanges and bolts and nuts. Since the connection between the flange and the bolts and nuts needs to be connected by four sets of bolts and nuts, the structure is complicated, the production process is difficult, and the cost is high. Higher, time-consuming and labor-intensive assembly, and at the same time, due to the circumferential shape of the flange and the protruding bolt and nut assembly with the high-speed rotation of the transmission shaft, it will generate greater noise and reduce transmission efficiency.
