Abstract
The utility model relates to a gear selecting and shifting control mechanism of a heavy truck and provides a double-pole control mechanism. The problem that an existing gear shifting mechanism is large in vibration and abnormal sound and the out-of-gear situation occur in the running process is solved. The double-pole control mechanism comprises a gear shifting mechanism, a gear selecting mechanism and a switching support. The switching support is fixed on a frame, a bushing is embedded into a gear shifting swing arm hole, and a shaft body of a gear shifting rotation shaft comprises a first cylinder, a second cylinder and a third cylinder which are sequentially decreased in bottom face diameter. Due to the fact that the switching support is fixed on the frame, vibration of a speed changing box can be preliminarily reduced and is continuously and upward transferred along the gear shifting rotation shaft, an axial gap is reversed between a gear shifting swing arm and the switching support after a nut is adjusted, the gear shifting swing arm can perform limited movement on the gear shifting rotation shaft during vibration, vibration energy is released at the position, the vibration is obviously reduced, and noise is correspondingly eliminated. The bushing embedded into the gear shifting swing arm hole can bear friction and impact produced by the gear shifting swing arm rotating and sliding along the gear shifting rotation shaft.
