Summary of the invention
The purpose of this utility model is to provide a kind of transmission transformational structure reasonable, unitary rotation intensity height, the multi-functional reinforcement gearbox that is used for motor tricycle, miniature four-wheel agricultural vehicle of long service life.
The purpose of this utility model is achieved in that a kind of multi-functional reinforcement gearbox, comprise the output main shaft, output mainshaft gear on the output main shaft, the output countershaft, output counter shaft gear on the output countershaft, and be positioned at the lower shift fork at output mainshaft gear place and be positioned at the upper shift fork of exporting the counter shaft gear place, it is characterized in that: described output mainshaft gear and described output main shaft are Spielpassung, and on described output main shaft, set up the output spindle clutch that spline fitted connects, the hole that is provided with on pusher dog that is provided with on the described output spindle clutch and described output mainshaft gear is slidingly matched, and the fork pockets of setting aside that is provided with on the described output spindle clutch matches with described lower shift fork.
Above-mentioned output spindle clutch can be positioned at the inner side surface of described output mainshaft gear, and the described fork pockets of setting aside that is provided with on the described output spindle clutch circumference can be circular groove.
Above-mentioned output counter shaft gear and described output countershaft also can be Spielpassung, and on described output countershaft, set up the output countershaft clutch that spline fitted connects, the pusher dog that is provided with on the pusher dog that is provided with on the described output countershaft clutch and described output counter shaft gear matches, and the upper shift fork groove and the described upper shift fork that are provided with on the described output countershaft clutch are slidingly matched.
Above-mentioned output countershaft clutch also can be positioned at the inner side surface of described output counter shaft gear, and the described upper shift fork groove that is provided with on the described output countershaft clutch circumference also can be circular groove.
The multi-functional reinforcement gearbox that the utility model provides is because output mainshaft gear and output counter shaft gear are in the moving state of normal engagement idle running, the phenomenon that can not produce mesh impact and break gear; The rotation of output main shaft and output countershaft or stop then respectively stirring output spindle clutch and output countershaft clutch and exporting the mainshaft gear hole and export the engagement of counter shaft gear pusher dog or separate and realize by two shift forks, all the time be in normal engagement between its driving gear, it is easy to reach the gear shift clutch, the non-damageable purpose of driving gear.
Therefore, the drive mechanism of the multi-functional reinforcement gearbox that is used for motor tricycle, miniature four-wheel agricultural vehicle that the utility model provides is reasonable, whole transmission intensity height, long service life.
