Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0013] Such as figure 1 , 2 As shown, a shift rocker assembly of a second-speed electric vehicle transmission assembly is composed of a shift rocker base 1, a rocker 2, a cable pin 3 and a rocker pin 4, and these four parts are all steel parts . Wherein, the shift rocker seat 1 is a "T" shape structure, and the two ends of the short arm section of the shift rocker seat 1 are respectively provided with a mounting hole 1a, and the mounting hole 1a is about the long arm of the shift rocker seat 1. Segment symmetry set.

[0014] The rocker arm 2 is a sheet structure, and a cable pin 3 is welded vertically at the lower end of the rocker arm 2. The left end of the cable pin 3 is a free end, and a cotter pin mounting hole 3a is formed at the free end. The cotter pin mounting hole has a diameter of 2.5mm and a tolerance of 2 wires. In this case, the cable pin 3 ...

Abstract

The invention discloses a gearshift rocker arm component of a bi-gear gearbox assembly of an electric vehicle. A gearshift rocker arm seat is of a 'T'-shaped structure, two ends of a short arm section of the gearshift rocker arm seat are provided with a mounting hole respectively, a rocker arm is of sheet structure, the lower end of the rocker arm is perpendicularly welded with a cable dragging pin, and a suspended end of the left end of the cable dragging pin is provided with a cotter mounting hole. A rocker arm pin is of bi-section type step structure larger in the left, the small-diameter section of the rocker arm pin penetrates a via hole of the upper end of the rocker arm firstly, then passes a via hole of the front side of a long-arm section of the gearshift rocker arm seat and is finally fixed by riveting, and the rocker arm and the gearshift rocker seat are fitted and can flexibly rotate. The upper end of the rocker arm is a matching portion matched with a gearshift rod, the top surface of the matching portion is a horizontal plane, the front and rear sides of the matching portion are curved surfaces, the curved surfaces are symmetrically arranged relative to the axis of the length direction of the rocker arm, and the rear side is 'S'-shaped. The gearshift rocker arm component is reliable to mount, and the gearshift rod can be effectively shifted after assembly.

Description

technical field [0001] The invention belongs to the field of transmissions, and in particular relates to a shift rocker arm assembly of a transmission assembly of a second-speed electric vehicle. Background technique [0002] The existing electric vehicle transmission assembly has a one-gear structure, that is, it cannot change gears, so its output torque and rotating speed cannot be adjusted according to road conditions, resulting in poor adaptability to road conditions. In order to overcome the above-mentioned technical defects, we want to specially design a transmission assembly with two gears. Simultaneously, in the design process, it is also necessary to design the shift rocker arm assembly accordingly. The shift rocker arm assembly must not only be installed securely, but also be able to move the shift lever effectively after assembly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a second-speed electric...
