Convex round fork of transmission output shaft

Abstract

The invention belongs to the field of automobile accessories, and relates to a convex round fork of a transmission output shaft. The convex round fork of the transmission output shaft is characterized in that a cylindrical spline cylinder is arranged in a connecting sleeve, a C-shaped convex round fork is arranged on the right side of the connecting sleeve, and a semicircular cross shaft mounting hole is formed in the center of each of the upper and lower top ends of the right side of the C-shaped convex round fork; the front side and the rear side of a cross shaft installation hole in the top end of the upper right side, the lower right side and the top end of the C-shaped convex round fork are each provided with a trapezoidal lock catch, the center of the right side face of each lock catch is transversely provided with a cylindrical bolt, and the right sides of two cross shaft installation holes in the top end of the upper right side, the lower right side and the top end of the convex round fork are each provided with a rectangular lock block, after the connecting sleeve is mounted on the transmission output shaft, the convex round fork in front of a transmission shaft is directly connected with the cross shaft mounting hole in the convex round fork of the transmission output shaft through the cross shaft, and then the cross shaft is locked through a locking block, so that the firmness and the torsion resistance of the convex round fork of the transmission output shaft are ensured; and the overall weight of the transmission shaft is effectively reduced.

Description

technical field [0001] The invention relates to a convex fork of an output shaft of a transmission, which belongs to the field of auto parts, and in particular relates to a transmission and a transmission shaft without support roller transfer, and the convex fork is directly connected to the transmission shaft. Background technique [0002] The utility model relates to a convex round fork, a cross shaft connection mechanism used for truck drive shafts. The existing manufacturers of transmission shafts, when processing the transmission shaft, use the convex fork on the top of the transmission shaft to pass through the cross shaft and the convex fork of the supporting roller, and then connect with the supporting roller behind the output shaft of the transmission when processing the transmission shaft. In order to facilitate the disassembly and assembly of the transmission shaft, bolts are used to connect the supporting wheel cam fork and the supporting wheel behind the transmi...

Problems solved by technology

The existing manufacturers of transmission shafts, when processing the transmission shaft, use the convex fork on the top of the transmission shaft to pass through the cross shaft and the convex fork of the supporting roller, and then connect with the supporting roller behind the output shaft of the transmission when processing the transmission shaft. In order to facilitate the disassembly and assembly of the transmission shaft, bolts are used to connect the supporting wheel cam fork and the supporting wheel behind the transmission output shaft. Since the truck needs to change the speed normally during driving, and the connecting bolts of the transmission shaft are normal for a long time After being subjected to impacts of different strengths, it will loosen and need to be tightened frequently. Moreover, existing trucks are tending to be lighter in weight. Due to the connection between the cam fork of the supporting wheel and the supporting wheel behind the output shaft of the transmission, the transmission shaft The overall weight of the assembly is too large
