Connect the shifting block mechanism be made up of reverse gear shifting block, a second gear shifting block, three fourth gear shifting blocks and five or six grades of shifting blocks bottom described fork-shaped driving lever, these four shifting block inside arrange reverse speed shift rod, a second gear declutch shift shaft, three shift fork shaft No 4s, five or six grades of declutch shift shafts successively respectively; In fork-shaped driving lever both sides, gear selecting lock pin, reverse gear lock pin are set respectively;
The above reverse gear shifting block, a second gear shifting block, three fourth gear shifting blocks and five or six grades of shifting blocks, in same plane, arrange seal ring above the gap above the gap between reverse gear shifting block wherein and a second gear shifting block and between three fourth gear shifting blocks and five or six grades of shifting blocks respectively;
Under the described shifting block mechanism be made up of reverse gear shifting block, a second gear shifting block, three fourth gear shifting blocks and five or six grades of shifting blocks, one deck protecting base plate is set up in bottom.
Correspondingly, following setting can be carried out:
At fork-shaped driving lever inside fixed installation speed change lever, there is reverse gear lock spring in reverse gear lock pin outer race; Described gear selecting lock pin is with locking plate.
The beneficial effect of automotive transmission reverse gear lock device described in the utility model is:
(1), by reverse gear shifting block and a second gear shifting block, between three fourth gear shifting blocks and five or six grades of shifting blocks, set up seal ring, phase mutual friction between each link stopper can be prevented and the situation that causes parts to consume;
(2) protecting cover is set in link stopper lower portion, is conducive to improving the wear-resisting property bottom each shifting block, reverse gear lock lower part structural stability can be guaranteed, be conducive to elongate member working life.
