Abstract
The utility model discloses a novel efficient synchronizer which comprises a support ring. The two ends of the support ring are respectively provided with a power transmission mechanism. A synchronizing sleeve is arranged inside the support ring. The synchronizing sleeve comprises a ring body, wherein a plurality of driving blocks are evenly arranged on the ring body, driving teeth are arranged on the inner surface of the support ring, and the driving teeth are connected with the driving blocks in a matched mode. A shifting fork is arranged on the support ring, wherein the shifting fork penetrates through the surface of the support ring to be connected with the synchronizing sleeve. The novel efficient synchronizer has the advantages that due to the fact that the structure that the driving teeth are matched with the driving blocks is applied, friction transmission is converted into torsion transmission; therefore, the synchronization torque is greatly increased, the synchronization time is shortened, the working range of the synchronizer is widened, the synchronization performance is greatly improved under the premise that the size of a gearbox is not changed, the gear shifting force is greatly reduced, the labor intensity of a driver is relieved, gear shifting is made to be smooth, the hand feeling is good, and the novel efficient synchronizer is particularly suitable for cars.
