Embodiment Construction

[0027] 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.

[0028] Such as figure 1 In the shown multi-speed transmission, eight forward gears can be realized through two first-stage deceleration structures and four two-stage deceleration structures, and the direct connection between the input shaft 10 and the output shaft 20 can be realized under the action of the synchronous structure 260 to realize Ninth forward gear; two one-stage deceleration structures cooperate with one reverse gear structure to realize two reverse gear outputs.

[0029] Such as figure 1The multi-speed transmission shown includes an input shaft 10, an intermediate shaft 30, an output shaft 20 and a reverse gear shaft 40. The input shaft 10 is coaxially connected with a driving gear 1 11 and a driving gear 2...

Abstract

The invention provides a multi-gear transmission and belongs to the technical field of transmissions. Through the multi-gear transmission, the problems that an existing multi-gear transmission is complex in structure and high in manufacturing difficulty. The multi-gear transmission comprises an input shaft, an intermediate shaft and an output shaft. A first-stage speed reduction structure I and afirst-stage speed reduction structure II are arranged between the input shaft and the intermediate shaft. A second-stage speed reduction structure I, a second-stage speed reduction structure II, a second-stage speed reduction structure III, a second-stage speed reduction structure IV and a reverse gear structure are arranged between the intermediate shaft and the output shaft in sequence. A synchronization structure I is arranged between the first-stage speed reduction structure I and the first-stage speed reduction structure II. A synchronization structure II is arranged between the first-stage speed reduction structure II and the second-stage speed reduction structure I. A synchronization structure III is arranged between the second-stage speed reduction structure II and the second-stagespeed reduction structure III. A synchronization structure IV is arranged between the second-stage speed reduction structure IV and the reverse gear structure. The multi-gear transmission has the advantages of being simple and compact in structure and low in cost.

Description

technical field [0001] The invention belongs to the technical field of transmissions, and relates to a multi-speed transmission, in particular to a multi-speed transmission with nine forward gears. Background technique [0002] Usually, multi-speed transmissions, especially nine-speed transmissions, are mostly realized by multiple planetary gear sets and friction elements, such as the multi-speed transmission of ZF Friedrichshafen Company (authorized notification number CN101109433A). Also have the part multi-speed transmission to be realized by elements such as multiple clutches, synchronizers and hollow gear shafts, such as the nine-speed dual-clutch transmission (authorized announcement number CN 105465295A) of Beijing Institute of Technology. The multi-speed transmissions with these structures are complex in structure, difficult to manufacture and expensive in cost. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned ...
