Abstract
The utility model is specially a kind of single control lever shaft six shift transmission and reverses gear independent mutual interlocking gear, solves existing single control lever shaft six shift transmission and there is by space and block selecting position limitation the problem that cannot interlock of reversing gear.Back fork is fixed with gearshift plate, gearshift plate on have gearshift groove, gearshift groove place be provided with the lock pin be inserted therein, housing is provided with stage clip plug screw, stage clip plug screw be provided with the locking spring be connected with both between lock pin; Handle and fork shaft is provided with outer end and is positioned at gear shift pin below lock pin; Housing is provided with the switch that reverses gear that lower end contact is close to back fork plane of inclination, the switch that reverses gear is provided with tutorial light.Time the utility model avoids and hangs forward gear, be linked into the problem of reversing gear simultaneously, achieve the independent interlocking of reversing gear, effective protection is played to speed changer, there is simple, the easy to process and advantage that cost is low of structure.
Description
Technical field
The utility model relates to speed changer mutual interlocking gear, is specially a kind of single control lever shaft six shift transmission and reverses gear independent mutual interlocking gear.
Background technique
The increasing of gear number of automotive transmission can improve the power utilization of motor, the fuel economy of automobile and average speed, its mutual interlocking gear often will be considered after can increasing a gear, can realize being a technical barrier with other gear interlocking, especially for the gearbox of single control lever shaft mechanism after increasing gear.
For the speed changer of single control lever shaft mechanism, mostly be five forward and a realization interlocking on an interlock board of reversing gear, there are three block selecting positions; And single control lever shaft six shift transmission to be six forward gears and one reverse gear, add a gear relative to five forward speed changer, but its interlocking just becomes complicated a lot.After increasing a gear, block selecting just adds a position, becomes four block selecting positions, cannot realize the interlocking of reversing gear from original three block selecting positions.
Summary of the invention
There is by space and block selecting position limitation the problem that cannot interlock of reversing gear in order to solve existing single control lever shaft six shift transmission in the utility model, provides a kind of single control lever shaft six shift transmission and to reverse gear independent mutual interlocking gear.
The utility model adopts following technological scheme to realize: single control lever shaft six shift transmission reverses gear independent mutual interlocking gear, comprise housing and the manipulation fork shaft being positioned at housing, handle cover on fork shaft and have back fork, back fork is fixed with gearshift plate, gearshift plate has gearshift groove, gearshift groove place be provided with the lock pin be inserted therein, housing is provided with stage clip plug screw, stage clip plug screw be provided with the locking spring be connected with both between lock pin; Handle and fork shaft is provided with outer end and is positioned at gear shift pin below lock pin; Housing is provided with the switch that reverses gear that lower end contact is close to back fork plane of inclination, the switch that reverses gear is provided with tutorial light.
When speed changer hangs over forward gear, under the effect of locking spring, lock pin inserts in the gearshift groove of gearshift plate, and lock pin exchange baffle plate and back fork carry out spacing, makes back fork can not axial motion, realizes the independent interlocking of reversing gear; When be linked into reverse gear time, gear shift pin upwards turns to and lock pin is ejected gearshift groove, and gear shift pin is arranged in gearshift groove, now gear shift pin moves axially and drives axial mobile being linked into of back fork to reverse gear, and overcomes existing single control lever shaft six shift transmission and there is by space and block selecting position limitation the problem that cannot interlock of reversing gear.
Housing is provided with the switch that reverses gear that lower end contact is close to back fork plane of inclination, reverse gear on switch and be provided with tutorial light, when back fork moves axially, the plane of inclination of the back fork switch contact that will reverse gear upwards lifts, make the closing of circuit at its place, tutorial light is bright, the effect of the warning played.
The utility model reasonable in design is reliable, avoids when hanging forward gear, is linked into the problem of reversing gear simultaneously, achieves the independent interlocking of reversing gear, play effective protection to speed changer, has simple, the easy to process and advantage that cost is low of structure.
