Description
Technical field
The utility model relates to a kind of auto parts and components, refers to a kind of upper cover of speed changing box assembly particularly.
Background technique
In prior art, automobile variable speed box cover assembly comprises the gear shift seat that is provided with different gear shift fork and the gear selecting seat for installing gear selection mechanism, the two is generally split-type design, namely gear shift seat top is provided with one piece of rectangular preiection, gear selecting seat is fixed by screws in projection, and then realizes the connection of gear shift seat and gear selecting seat.This kind of Placement causes whole gearbox volume bigger than normal, and size is higher, is unfavorable for entire vehicle design, and when being arranged on automobile, the protruding car floor of meeting, effectively cannot utilize motor space.
In addition, the gear level orientation type for gear selecting adopts left and right to arrange balance spring mode, because spring location belongs to flexible location, there is gear level gear selecting and locates unsharp problem.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, provides one to reduce setting height(from bottom) and has the clear assembly of upper cover of speed changing box accurately in gearshift location.
The technical solution of the utility model is: a kind of upper cover of speed changing box assembly, comprise gear shift seat and the gear selecting seat being positioned at described gear shift seat top, gear selection mechanism is provided with in described gear selecting seat, be provided with multiple for being used in combination from described gear selection mechanism and there is the shift fork of different gear in described gear shift seat, it is characterized in that: described gear selecting seat and described gear shift seat are integral type structure, described gear selecting seat is provided with the mounting hole for installing described gear selection mechanism, described mounting hole is through along axis, described mounting hole closed upper part, described mounting hole bottom communicates with described gear shift seat.
Further, described gear selection mechanism comprises the shifting shaft be arranged in described mounting hole, described shifting shaft one end passes described mounting hole and concordant with described gear selecting seat one end, the described shifting shaft the other end passes described mounting hole and the gear selecting seat the other end successively, and the described shifting shaft the other end is connected with the gear arm of perpendicular setting; Shifting shaft in described mounting hole is set with successively the first balance spring, gear level and the second balance spring, described gear level and be respectively arranged with the first positioning spacer and the second positioning spacer between described first balance spring and the second balance spring, described first balance spring is fixedly connected with between described mounting hole one end sidewall and the first positioning spacer, and described second balance spring is fixedly connected with between described second positioning spacer and mounting hole the other end sidewall.
Further, described gear selecting seat is symmetrical arranged along the axial Vertical direction of described shifting shaft.
Gear shift seat and gear selecting seat are designed to the superstructure of integral type by the utility model, the rectangular preiection being positioned at gear shift seat top can be cancelled, reach the object reducing gear selecting seat and whole gearbox setting height(from bottom), more virtuously can utilize motor space in background technique; And the positioning spacer with different length is set between gear level and the balance spring at its two ends, realize shift level rigidity location, the clear object accurately in gearshift location.
Accompanying drawing explanation
