Abstract
The utility model discloses a lock pin type synchronizer. The lock pin type synchronizer comprises a first synchronous loop, a sliding gear sleeve and a second synchronous loop. The first synchronous loop is provided with a synchronous spring installation groove with a linkage hole, and the sliding gear sleeve is provided with a locking hole. The second synchronous loop is provided with a long linkage pin which penetrates through the locking hole and is inserted into the linkage hole. A tension spring structure used for tensioning the first synchronous loop and the second synchronous loop is arranged between the first synchronous loop and the second synchronous loop and comprises a tension spring and a tension spring penetration hole formed in the sliding gear sleeve, the aperture of the tension spring penetration hole is matched with the diameter of the tension spring, one end of the tension spring is installed on the first synchronous loop, and the other end of the tension spring penetrates through the tension spring penetration hole and is installed on the second synchronous loop. Through the tension spring structure between the first synchronous loop and the second synchronous loop, the distance between the first synchronous loop and the second synchronous loop can keep unchanged, and therefore the long linkage pin is effectively prevented from being separated from the linkage hole, and the service life of the synchronizer is prolonged. The technical scheme is suitable for the synchronizer.

Technical field
The utility model relates to synchronizer field, particularly relates to a kind of pin-type synchronizer.
Background technique
At present, pin-type synchronizer is generally used in the twin countershaft transmission odd-side of medium and heavy cargo vehicle.This pin-type synchronizer generally comprises the first synchronizing ring, sliding gear collar and the second synchronizing ring, the first synchronizing ring is provided with the synchronisation spring mounting groove in band interlock hole, on sliding gear collar, the position in corresponding interlock hole is provided with locking hole, and the second synchronizing ring is provided with the interlock that runs through locking hole and be inserted in interlock hole and has strong market potential.There is in actual use following problem in this pin-type synchronizer:
Due to the work under bad environment of pin-type synchronizer, so this pin-type synchronizer used after the time of one end, its first synchronizing ring, sliding gear collar and the second synchronizing ring can be worn and torn, cause the spacing between the first synchronizing ring and the second synchronizing ring to become large, like this, easily occur that interlock has strong market potential from the phenomenon of deviating from interlock hole, thereby cause this pin-type synchronizer to lose efficacy.
Summary of the invention
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, and a kind of pin-type synchronizer of long service life is provided.
In order to realize above object, a kind of pin-type synchronizer that the utility model provides, comprise the first synchronizing ring, sliding gear collar and the second synchronizing ring, described the first synchronizing ring is provided with the synchronisation spring mounting groove in band interlock hole, on described sliding gear collar, the position in corresponding described interlock hole is provided with locking hole, described the second synchronizing ring is provided with the interlock that runs through described locking hole and be inserted in described interlock hole and has strong market potential, between described the first synchronizing ring and the second synchronizing ring, be provided with the extension spring structure for described the first synchronizing ring and the second synchronizing ring are strained mutually, described extension spring structure comprises extension spring and is arranged in extension spring on described sliding gear collar through hole, described extension spring matches through the aperture in hole and the diameter of described extension spring, described extension spring one end is arranged in described the first synchronizing ring, the described extension spring the other end is arranged in described the second synchronizing ring through hole through described extension spring.Can guarantee that by the extension spring structure adding between described the first synchronizing ring and the second synchronizing ring the spacing between described the first synchronizing ring and the second synchronizing ring remains unchanged, deviate from described interlock hole thereby effectively avoided described interlock to have strong market potential, extended the working life of this synchronizer.
In such scheme, the sidewall of described synchronisation spring mounting groove is provided with the first mounting hole of described extension spring being installed for articulating.
In such scheme, described the second synchronizing ring is provided with the second mounting hole of described extension spring being installed for articulating.
The utility model can guarantee that by the extension spring structure adding between described the first synchronizing ring and the second synchronizing ring the spacing between described the first synchronizing ring and the second synchronizing ring remains unchanged, deviate from described interlock hole thereby effectively avoided described interlock to have strong market potential, extended the working life of this synchronizer.
The utility model is compared with the prior art, and fully shows that its superiority is: long service life, simple in structure and easy to assembly.
