Embodiment Construction

[0025] Elaborate in detail below in conjunction with accompanying drawing and a kind of embodiment of the present invention:

[0026] The design of synchronous ring and locking pin of the present invention has adopted a kind of new structure, see Figure 4 As shown, a locking pin type synchronizer includes a synchronizing ring 1 and a locking pin 2, the synchronizing ring 1 includes a body and a protrusion, the body and the protrusion are an integral structure, and the protrusion The part is formed by continuing to extend from the end face of the main body; the protruding part of the synchronous ring is provided with a pin hole; the locking pin 2 is installed in the pin hole of the synchronous ring.

[0027] read on Figure 4 As shown, the outer diameter of the protrusion of the synchronous ring 1 is smaller than the difference between the outer diameter and the inner diameter of the synchronous ring body; the outer end surface of the protrusion of the synchronous ring is pro...

Abstract

The invention discloses a lockpin synchronizer which comprises a synchronizing ring, a lockpin and a slide sleeve. The synchronizing ring comprises a body and a protrusion integrated to each other. The protrusion of the synchronizing ring is provided with a pinhole, and the lockpin is disposed in the pinhole of the synchronizing ring. The synchronizing ring with the protrusion contacts with the slide sleeve during synchronization, so that most force is borne by the protrusion of the synchronizing ring during moving of the synchronizer, and the lockpin bears small force only.

Description

technical field [0001] The invention relates to a synchronizer, in particular to a pin type synchronizer. Background technique [0002] There are mainly two types of gearbox synchronization devices: lock pin type and lock ring type. Among them, the lock pin type synchronizer is widely used in the auxiliary box position of pneumatic gear shifting because of its simple structure and durable leather. Lock pin synchronizers have a large stock in the heavy truck gearbox market with auxiliary boxes. [0003] In the lock pin type synchronizers that are common in the market, the lock pin and the synchronization ring generally adopt the following connection methods: 1) The lock pin and the corresponding hole on the synchronization ring are press-fitted with interference fit, and after the press fit, the lock pin Tail press riveting, see figure 2 , image 3 ; 2) The locking pin and the synchronizing ring are connected by bolts. Among these two ways, the first one is the most. [...
