Manual shift gearbox operating device is because it is simple in structure, and is cheap and be used widely, but manual shift gearbox operating device must execute-in-place, promptly can not telecontrol; In addition, because all around move during gear shift operating rod conversion gear, the front end wearing and tearing that cause gear shift operating rod contact easily with shift fork, the gear shift operating rod after the wearing and tearing causes misoperation (promptly hanging mistake keeps off) easily; Also have; The possibility (can make most of damage of gear in the gearbox like this) that hangs up two retainings simultaneously in order not allow gearbox to have, manual shift gearbox operating device must cooperate gearbox interlock (a kind of device that lets gearbox can only hang over a gear all the time) normally to move.
Summary of the invention
The purpose of the utility model is the above-mentioned deficiency that overcomes existing technology; Realize the electronic manual transmission operating device of gearbox shifting with electric pushrod as power and provide a kind of, can not telecontrol to improve manual shift gearbox operating device, gear shift operating rod wearing and tearing back hangs wrong retaining and defective that can not isolated operation easily.
The technological scheme of the utility model is: a kind of electronic manual transmission operating device; It comprises gearbox, declutch shift shaft, shift shift fork, gearshift driving lever and gearshift push rod; Declutch shift shaft and shift shift fork are installed on the case lid of gearbox; Declutch shift shaft is made up of left declutch shift shaft, middle declutch shift shaft and right declutch shift shaft, and shift fork is made up of left shift fork, middle shift fork and right shift fork; The gearshift driving lever is made up of shift gears driving lever, middle gearshift driving lever and right gearshift driving lever of a left side, and the one of which end is connected with the push rod of shifting gears, and the other end is connected with the shift shift fork; The gearshift push rod is made up of shift gears push rod, middle gearshift push rod and right gearshift push rod of a left side, and the gearshift push rod is installed on the case lid of gearbox, and the one of which end is connected with the driving lever of shifting gears, and the other end is connected with motor drive mechanism.
The further technological scheme of the utility model is: the push rod box is arranged on the case lid of gearbox, and the gearshift push rod is installed in the push rod box.
The utility model more further technological scheme be: the gearshift push rod is connected with the driving lever of shifting gears with boss on it through back-up ring.
The utility model technological scheme further is: the clutch tommy bar is arranged on the clutch, and the clutch tommy bar is connected with motor drive mechanism through clutch push rod.
The utility model compared with prior art, has following characteristics owing to adopt as above design:
1, can carry out telecontrol easily: the utility model adopts electronic manual transmission operating device to replace manual shift gearbox operating device, has solved the difficult problem of manual transmission operating device telecontrol effectively.
2, easy to operate accurately can not hang the mistake retaining: the utility model adopts independent driving lever (left and right driving lever and middle driving lever) to control left and right shift fork and middle shift fork respectively, only can not hang wrong retaining selecting wrong the retaining, and is easy to operate accurate.
3, simple in structure: the utility model is aided with circuit control, once can only move a gearshift push rod, the isolated operation so need not to install the gearbox interlock.
Further describe below in conjunction with accompanying drawing and embodiment detailed structure the utility model.
