Gearbox shift blocks arrangement and working principle

Gearbox shift blocks arrangement:

The gearbox shift block is generally located on the transmission shifting rocker arm. It can be designed separately, bolted to a specific position of the shifting rocker arm, or it can be designed integrally with the shifting rocker arm to make a part. The current gearbox The arrangement of the shift block is mainly divided into two types: one is that the balance block is horizontally arranged with the shifting rocker arm, and the shifting rocker arm of the gearbox moves on the horizontal surface, and the gravity of the balance block does not work during the movement, one is The balance block is non-horizontally arranged with the shifting rocker arm. The shifting rocker arm of the gearbox moves on the non-horizontal surface. During the movement, the gravity of the balance block works. At present, most of the passenger car gearboxes have higher requirements for shifting performance. The product adopts the above-mentioned first arrangement, and the commercial vehicle gearbox and the products requiring general shifting performance, including the design of the gearbox itself, cannot be arranged in a horizontal arrangement, and are in the second arrangement.

The working principle of the gearbox shift blocks:

In either form, the basic working principle is to store a certain amount of energy at the initial speed when the shifting rocker swings, and to release the stored energy in the synchronous phase and the later stage, thereby reducing the shifting force. Reduces secondary impact and improves the sense of inhalation, which in turn improves the comfort of shifting.
