Embodiment Construction

[0037] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0038] Such as figure 1 with figure 2 As shown, the buffer mechanism of the automatic transmission, the automatic transmission includes a main shaft 1 and an input assembly 2 axially fixed on the main shaft 1 and rotatable. The input gear 2a on the main shaft 1 and the transmission support 2b and the clutch structure that can make the input gear 2a and the transmission support 2b synchronize in the circumferential direction when the rotation speed of the input gear 2a is greater than that of the main shaft 1 . In addition to the input assembly 2, the main shaft 1 is provided with an inner ring 8 and the inner ring 8 forms a linkage relationship with the main shaft 1. The main shaft 1 is axially fixed with a transmission ...

Abstract

The invention provides a buffer mechanism of an automatic transmission, and belongs to the technical field of speed change devices. The buffer mechanism solves the problem that an existing buffer mechanism is short in buffer stroke and insufficient in buffer effect. The buffer mechanism comprises a buffer shell which is fixed on a main shaft in the circumferential direction and abuts against an input component, the face, facing the input component, of the buffer shell is provided with an annular cavity, and the annular cavity is internally provided with an annular first elastic buffer component with the head and tail ends. When the input component rotates, the head end of the first elastic buffer component can be driven to move along the annular cavity, the annular cavity includes an innerring groove and an outer ring groove which are independent of each other, the first elastic buffer component is arranged in the outer ring groove, an annular second elastic buffer component with thehead and tail ends is arranged in the inner ring groove, the head end of the second elastic buffer component is fixedly connected with the tail end of the first elastic buffer component, and the tailend of the second elastic buffer component is fixedly connected with the buffer shell. The buffer mechanism has the advantages of being long in buffer stroke, good in buffer effect, low in cost and the like.

Description

technical field [0001] The invention belongs to the technical field of transmission devices, and relates to a two-way automatic transmission, in particular to a buffer mechanism of the automatic transmission. Background technique [0002] The two-way automatic transmission is applied in the electric tricycle, and it is used to realize the forward or reverse of the vehicle, and the speed change between low speed and high speed during the forward process. In order to solve the problem of scattered parts and too much space occupied by traditional two-way automatic transmission devices, the applicant once proposed a two-way automatic transmission motor transmission device with patent application number 201510424829.9, which realizes the forward and reverse functions of electric tricycles. , which greatly reduces the space occupied by the entire transmission device, making the entire structure simpler. However, when the device is switched from low speed to high speed, the direct...
