Abstract
The utility model belongs to automotive transmissions and particularly discloses a transmission top cover provided with a gear shift self-locking and interlocking mechanism, which is characterized in that the top cover is provided with a gear selecting shaft assembly and a gear shift shaft; a gear selecting and shifting block and an interlocking sleeve are respectively sleeved on the gear shift shaft and move along with the rotating of the gear selecting shaft assembly; a positioning groove is arranged on the gear selecting and shifting block; a positioning pin is arranged in the positioning groove on the gear selecting and shifting block; the interlocking sleeve is clamped in a gear shifting fork groove and can freely move; and the interlocking sleeve is provided with only one gear groove for the gear selecting and shifting block to swing. During working of the utility model, the positioning pin arranged on the top cover falls in the positioning groove of the gear selecting and shifting block to realize gear shift positioning and self-locking; and the interlocking sleeve is provided with only one gear groove to realize gear shift interlocking. The transmission top cover is provided with the gear shift self-locking and interlocking mechanism, therefore, the processing technique of a transmission shifting fork shaft and the transmission top cover (or a shell) is simplified, the parts of an operating mechanism are reduced, the assembling and maintenance technique of an operating mechanism assembly is simplified, and the cost is lowered.
Description
Technical field
The utility model belongs to the automotive transmission class, specifically is a kind of speed changer top cover with gear shift self-locking and mutual interlocking gear.
Background technique
At present, domestic employed five grades (or six grades) light-duty, compact car speed changers, its gearshift mechanism adopts three fork shafts to add three shift forks (or four fork shafts add four shift forks) usually, its shortcoming is: the processing technology complexity of fork shaft, speed changer loam cake (or housing), the assembly technology complexity of transmission assembly, the cost height.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provide a kind of simple in structure, use the band gear shift self-locking reliable, easy to maintenance and the speed changer top cover of mutual interlocking gear.
The utility model is realized with following technical proposal:
A kind of speed changer top cover with gear shift self-locking and mutual interlocking gear, it is characterized in that: shift selection shaft assembly, shift shaft are arranged on the top cover, gear-changing and selecting shifting block, interlocking cover are enclosed within respectively on the shift shaft and move with the rotation of shift selection shaft assembly, locating slot is arranged on the gear-changing and selecting shifting block, locating stud drops in the locating slot on the gear-changing and selecting shifting block, the interlocking cover is stuck in the reverse shift fork groove and can moves freely, and the interlocking cover only is provided with a gear groove, for the gear-changing and selecting shifting block swing.
The utility model work the time is located at locating stud on the top cover and drops in the locating slot on the gear-changing and selecting shifting block and realize gear shift location self-locking; Interlocking cover is only established a gear groove, has limited the moving of reverse shift fork of other gear, and gear-changing and selecting shifting block can only be stirred a required reverse shift fork, has realized the gear shift interlocking.
The top cover of the utility model speed changer is provided with gear shift interlocking and self-locking mechanism, simplified the processing technology of gearshift fork fork shaft, speed changer loam cake (or housing), reduce the component of operating mechanism, simplified assembling, the maintenance process of control mechanism assembly, reduced cost.
