Transmission mechanism of bidirectional automatic gearbox

Abstract

The invention provides a transmission mechanism of a bidirectional automatic gearbox and belongs to the technical field of machinery. The transmission mechanism solves the problem of low work stability of existing bidirectional automatic gearboxes. The transmission mechanism comprises a main shaft, an inner ring circumferentially fixed to the main shaft, an outer ring sleeving the inner ring and acombining sleeve sleeving the main shaft; a disengagement structure is arranged between the outer ring and the combing sleeve, the outer ring is internally connected with a connecting disc through apositioning structure circumferentially, avoidance segments and first combining segments are arranged on the outer side of the inner ring, first rolling columns are positioned on the connecting disc,and the lower end of the combining sleeve penetrates through the connecting disc and is inserted into the upper end face of the inner ring. When the outer ring rotates in a forward movement directionof a car, the first rolling columns are located at the avoidance segments, and the inner ring and the outer ring slip. When the outer ring rotates in a reverse movement direction of the car, the lowerend of the combing sleeve is retracted into the connecting disc, and the connecting disc drives the first rolling columns to move to the first combining segments and makes the inner ring circumferentially connected with the outer ring. The transmission mechanism has the advantages of being high in work stability, simple in structure and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a two-way automatic transmission, in particular to a transmission mechanism of the two-way automatic transmission. Background technique [0002] The traditional two-way automatic variable speed motor realizes the forward or reverse of the electric tricycle through the cooperation of the one-way chuck and the forward one-way device and the reverse one-way device. Scattered distribution, excessive space occupation and other issues. Based on these problems, the applicant has improved the existing technology and applied for a two-way automatic variable speed motor transmission [application number: 201510424829.9]. The space occupied by the entire transmission device is reduced, and the entire structure becomes simpler. However, it also has relatively obvious defects, that is, the separation mechanism related to the forward and reverse cars has extremely high requirements for the ass...

Problems solved by technology

[0004] However, the abutting part and the blocking part are in a state of relative rotation, that is, the blocking part and the abutting part can only be formed after the blocking part is rotated close to the abutting part, but according to practical experience, two mutually The separate parts need to form abutment after rotation, which requires very high requirements for the angle of rotation and the height position between the parts, which often causes the blocking part and the abutting part to not fit in place or not stable enough during use. , so that the blocking part and the abutting part come into contact and then separate, resulting in poor working stability of the entire transmission
