Description
Technical Field
The utility model relates to a split type gear shifting mechanism assembly.
Background
The shell of the traditional gear shifting mechanism is of an integrated structure and has the defect of inconvenient disassembly; and because the motorcycle type is different, and the shape to the gearshift casing and the external dimension require differently, need design corresponding mould to process for different motorcycle types configuration gearshift casing, not only increased the design manufacturing cost, but also reduced production efficiency, had the shortcoming that the commonality is poor.
There is also split type gearshift among the prior art, for example CN208719326U discloses a split type casing for use in gearshift, and the technical scheme adopted is: the shell comprises an upper shell and a lower shell which are arranged from top to bottom, and the upper shell and the lower shell are of split structures; the bottom of the upper shell is provided with a base, the base and the upper shell are of an integrated structure, the lower shell is provided with a plurality of threaded holes, the base of the upper shell is provided with a plurality of notches matched with the threaded holes of the lower shell, and bolts penetrate through the notches and the threaded holes to fixedly connect the upper shell and the lower shell; the device structural design is reasonable, and the commonality is strong, has reduced manufacturing cost, has improved production efficiency.
However, the above-mentioned scheme has the following defects that firstly, the operating rod and the upper shell are easy to collide firmly in the operating process, and then vibration is caused, so that the loosening and loosening phenomenon of the connecting bolt is easily caused, and the phenomenon of noise generation can be caused by the fact that the upper shell and the base are shaken after the connecting bolt is loosened.
This company has applied for CN202020573866.2 a split type gearshift, which has an insert block on the connecting ear plate, which can prevent the bolt from loosening caused by vibration, but because the vibration of the upper housing is transmitted to the base, the base is easy to loosen, so it is necessary to improve the above structure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provides a split type gear shifting mechanism assembly which can prevent a connecting bolt from loosening and ensure the stability of a base.
In order to realize the technical effects, the technical scheme of the utility model is as follows: a split type gear shifting mechanism assembly comprises a base, an upper shell connected with the base in a detachable mode, a gear hole allowing an operating rod to pass is formed in the top surface of the upper shell, a plurality of connecting lug plates are fixedly horizontally arranged on the outer contour of the lower end face of the upper shell, a plurality of positioning grooves corresponding to the connecting lug plates are formed in the upper end face of the base, connecting holes corresponding to the connecting lug plates and used for installing connecting bolts are formed in the connecting lug plates and the positioning grooves, mounting grooves extending along the horizontal direction are formed in the side end faces of the connecting lug plates, slots communicated with the mounting grooves are formed in the bottom faces of the connecting lug plates, elastic cushions matched with the mounting grooves are arranged in the mounting grooves, elastic positioning connecting pieces are fixedly connected to the bottoms of the elastic cushions and penetrate through the slots, and limit grooves communicated with the elastic positioning pieces are formed in the positioning grooves, the elastic positioning joint piece is matched with the limiting groove, and the elastic cushion and the elastic positioning joint piece are all provided with through holes for the connecting bolts to pass through.
In a further refinement, the resilient cushion is integrally formed with the resilient locating tab.
In a further refinement, the elastic cushion and the elastic locating engagement are both made of rubber.
In a further refinement, the cross-sections of both the resilient cushion and the resilient positioning link are T-shaped.
The utility model has the advantages and beneficial effects that: set up the mounting groove at the side end face of connecting the otic placode, set up the elastic cushion in the mounting groove, its effect can effectively prevent connecting bolt pine and take off in the gasket, guarantees the stability of connecting, and the elastic locating linking piece of its lower part still cooperates with the spacing groove in the constant head tank on the base in addition, has set up the buffer member between casing and base in other words, has reduced the vibration that the casing transmitted for the base from this, has guaranteed the stability of base.
