Description
Technical Field
The utility model relates to the field of automotive technology, specifically a shift fork connection structure.
Background
The shifting fork is a component on an automobile gearbox, is connected with a speed change handle and is positioned at the lower end of the handle, and shifts a middle speed change wheel to change the input/output speed ratio, so that the shifting fork is mainly used for shifting gears of a clutch.
And present heavy-duty car differential lock is used more and more frequently, in order to guarantee that the differential lock is worked steadily swift high-efficient, traditional differential lock structure is because the tangent line of shift fork and meshing sleeve contacts for the line contact, consequently is not steady in the motion, makes the meshing sleeve damage more, consequently has certain security problem to traditional shift fork is with clearance connection between the shift fork axle, and shimming adjustment spring return force needs test the adjustment repeatedly to the number that increases the gasket, leads to the operation flow inefficiency.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a shift fork connection structure solves the technical problem who mentions in the above-mentioned background art:
the purpose of the utility model can be realized by the following technical proposal:
the utility model provides a shifting fork connection structure, includes the shifting fork body and is located the shifting fork axle on the shifting fork body, its characterized in that, the external screw thread has been seted up to the surface of shifting fork axle, threaded hole is run through to one side of shifting fork body, the internal surface and the external screw thread threaded connection of screw hole, the open slot has been seted up to one side of screw hole inner chamber, one side of shifting fork body is run through and has been seted up the counter sink, the internal surface threaded connection in counter sink has fastening screw, the surface cover of shifting fork axle is equipped with the spring, the both sides of shifting fork body are all run through and have been seted up the connecting hole, the internal surface fixed connection of connecting hole has the gasket that contacts with the meshing mantle surface.
As a further aspect of the present invention: one side of the gasket is provided with an arc surface.
As a further aspect of the present invention: one end of the shifting fork shaft is provided with a tangent plane for connecting the shaft.
The utility model has the advantages that: set up the gasket through the both sides at shift fork body inner wall to set up the cambered surface with one side of gasket and meshing cover surface looks adaptation, thereby can increase area of contact, and then make poor meshing cover motion more steady, and compare in prior art through increasing gap junction adjustment spring return force between gasket adjustment shift fork body and the declutch shift shaft, this application is through the shift fork body with adjust spring return force for bolted connection between the declutch shift shaft, pin the shift fork with fastening screw, convenient and fast.
