During assembling, gear shifting rocking arm seat (1) is fixed on transmission assembly by the screw be located in mounting hole (1a), the auxiliary section (2a) of described rocking arm (2) snaps in the gear shift groove of shift level, and is fixed with a drag-line in the cotter pin mounting hole (3a) of dragline pin (3).During use, dragline pin (3) is driven to swing by pulling drag-line, and then drive rocking arm (2) to swing around rocker-arm roller pin (4), thus drive shift level to move by the auxiliary section (2a) of rocking arm (2), and then gear shift.
Adopt above technological scheme, it is firm that the present invention can install, and effectively can stir shift level after assembling, and then realize gear shift, and structure of the present invention is simple, easy to implement, and assembling easily.
Two described mounting holes (1a) are symmetrical arranged about long-armed section of gear shifting rocking arm seat (1), facilitate like this and install fixing the present invention securely; Described dragline pin (3) is two-part hierarchic structure left small and right large, the path section of this dragline pin is through after the via hole of described rocking arm (2) lower end, its large footpath section and rocking arm (2) are welded and fixed, and this makes it possible to conveniently, be fixed on rocking arm (2) by dragline pin (3) securely.
As optimization, described gear shifting rocking arm seat (1), rocking arm (2), dragline pin (3) and rocker-arm roller pin (4) are steel part entirely.
Beneficial effect: it is firm that the present invention can install, and effectively can stir shift level after assembling, and then realize gear shift, and structure of the present invention is simple, easy to implement, assembling is easily.
Accompanying drawing explanation
Fig. 1 is outline drawing of the present invention;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, 2, a kind of gear shifting rocking arm assembly of second gear electric vehicle transmission assembly, is made up of gear shifting rocking arm seat 1, rocking arm 2, dragline pin 3 and rocker-arm roller pin 4, and these four parts are steel part entirely.Wherein, gear shifting rocking arm seat 1 is " T " character form structure, and the two ends of this gear shifting rocking arm seat 1 galianconism section have a mounting hole 1a, and this mounting hole 1a is symmetrical arranged about long-armed section of gear shifting rocking arm seat 1.
Described rocking arm 2 is sheet structure, is vertically welded with a dragline pin 3 in the lower end of rocking arm 2, and the left end of this dragline pin 3 is free end, and has a cotter pin mounting hole 3a at this free end, and the aperture of this cotter pin mounting hole is 2.5mm, and its tolerance is 2.In the present case, described dragline pin 3 is two-part hierarchic structure left small and right large, and the path section of this dragline pin 3 is through after the via hole of described rocking arm 2 lower end, and the large footpath section of dragline pin 3 and rocking arm 2 are by being welded and fixed.
