[0002] The shifting control devices of current three- and four-wheeled motorcycles are usually provided with a shifting manipulator assembly. This shifting manipulator assembly includes upper and lower housings and joysticks. plate, the lower housing is provided with a vertical rotation pin and a horizontal rotation pin, and the horizontal and vertical rotation of the shift lever is realized through the two criss-cross pins. This structure requires the support of the vertical rotation pin and the horizontal rotation pin respectively Shaft support, and two torsion springs need to be set separately to realize the return of the joystick, and an interlocking device for longitudinal rotation and lateral rotation restriction needs to be set, the structure is relatively complicated, and the cost is high; and the two torsion springs The assembly is also more complicated, and the labor intensity of the workers is high

The invention discloses a gear-shift operating mechanism of a three-wheel motor cycle or a four-wheel motor cycle, comprising a gear locating plate arranged on a frame, a gear-shift operating rod passing through the gear locating plate, a gear-shift rocker arm connected with the shift shaft of an engine, and a pull rod connected between the gear-shift operating rod and the gear-shift rocker arm; the lower end of the gear-shift operating rod is connected with a support saddle arranged on the frame by a ball-head connection device; a return tension spring is connected between the gear-shift operating rod and the frame; the rod part of the gear-shift operating rod is provided with a hinge arm used for being articulated with a pull rod; the hinge arm is articulated with a T-typed connector at one end of the pull rod; the other end of the pull rod is connected with the gear-shift rocker arm by a ball-head connection device; a mounting plate arranged on the engine limits the gear-shift rocker arm by an arranged locking pin. The gear-shift operating rod is connected with the frame by the ball-head connection device, so that the structure is simplified, thus reducing the cost greatly.
