Abstract

The invention provides a valve bridge, which relates to the technical field of engine accessories, and solves the technical problems of poor damping and noise reduction performance and short service life of the valve bridge in the prior art. The valve bridge includes a bridge body, a carrier, a pad and a shock absorber, wherein a through hole is arranged on the bridge body; the carrier is arranged in the through hole, and the pad and the bearing The body is connected; the cushion block is arranged in the through hole, and the transition fit between the cushion block and the bridge body; the shock absorbing part is arranged between the bearing body and the cushion block. The present invention is used at the engine valve, adopts the movable connection and the damping structure of the shock-absorbing part, plays the role of shock-absorbing and noise-reducing. It acts on one point, significantly improving the life of the block.

Description

technical field [0001] The invention relates to the technical field of engine accessories, in particular to a valve bridge. Background technique [0002] With the rapid development of diesel engines and the increasing pursuit of noise reduction, the original models are limited in terms of space and rigidity, and it is impossible to arrange hydraulic tappets or hydraulic rocker arms related oil passages and components. The traditional design will impact the rocker arm. The load acts on the center of the bridge, so that the rocker arm always acts on the center of the bridge, which causes the impact force to act at one point, and it is easy to cause fatigue damage when used for a long time. [0003] Therefore, it is necessary to design a valve bridge to solve the problems of poor damping and noise reduction performance and short service life of the current valve bridge. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a valve crossing brid...
