Problems solved by technology
[0003] Since the tooth sleeve of the above-mentioned synchronizer assembly and the combined teeth of the target gear are splined, in order to prevent it from automatically disengaging, it is necessary to process a reverse tapered surface at the end of the spline tooth, which increases the processing difficulty of the parts. Increased parts manufacturing cost; In addition, the synchronizer assembly has a large number of parts and complex structure, and the quality of processing and assembly is not easy to guarantee, resulting in a decrease in the reliability of the shifting transmission mechanism. During the operation of the vehicle, the failure of the synchronizer assembly caused Problems such as gear drop and gear shifting occur from time to time

A bidirectional clutch gear shifting drive mechanism for an automotive transmission is used for solving the problems that an existing synchronizer gear shifting drive mechanism is complicated in structure, and machining and assembling accuracy of parts is not easily ensured. The bidirectional clutch gear shifting drive mechanism comprises a drive shaft, a bidirectional clutch and a target tap gear, the bidirectional clutch comprises an inner ring, an outer ring, a holding frame and a rolling element, the inner ring is connected with the drive shaft through a spline, the outer ring is connected with the target tap gear through a spline, the holding frame is of a circular structure, the holding frame, the inner ring and the rolling element are assembled, and an annular groove matched with a transmission shifting fork is formed in the outer wall of the holding frame. A bidirectional clutch structure replaces a synchronizer component of a traditional gear shifting drive mechanism, so that the manufacturing cost of a transmission drive mechanism is reduced, and reliability of an automotive gear shifting system is improved.
Description
technical field [0001] The invention relates to a shifting transmission mechanism of an automobile transmission, in particular to a two-way clutch type shifting transmission mechanism of an automobile transmission, which belongs to the technical field of transmissions. Background technique [0002] At present, the shift transmission mechanism of a general mechanical transmission adopts a synchronizer assembly, and the torque is transmitted through the tooth sleeve spline and the coupling tooth spline. The synchronizer assembly includes range gear coupling teeth, synchronizing ring, gear hub and gear sleeve. During the shifting operation, the gear sleeve drives the synchronous ring to slide in the direction of the target gear combination teeth, and the friction force is generated through the cooperation between the inner conical surface of the synchronous ring and the outer conical surface of the target gear combination teeth, so that the speed of the input shaft is consisten...
