Central traction rubber sleeve is installed in traction seat, is directly connected with car body, and is the core component in traction device.

[0003] In order to adapt to the relative motion between car body and bogie in passenger train operation, the existing central traction rubber sleeve adopts rubber elastic structure to realize the elastic traction braking of vehicle, and the existing central traction rubber sleeve is generally formed by steel outer sleeve, steel inner sleeve and rubber vulcanization, and symmetrical uniform structure is adopted in circumferential direction.

[0004] Due to the large acceleration and deceleration of passenger train vehicle traction braking, a large traction braking force is generated, so that the longitudinal displacement of vehicle is large during traction braking, which easily causes the longitudinal interference problem between vehicle parts and generates a large longitudinal impulse. In order to solve this problem, the utility model provides a restraint type central traction rubber sleeve. UTILITY MODEL CONTENT
