Negative pressure booster for vehicle braking system - makes use of U=shaped component with rubber spring layers attached

摘要

The negative pressure brake booster is for a vehicle braking system. The axial movement of the two control housing components is defined by a U-shaped part working in conjunction with two contact surfaces. The U-shaped part (17) is formed by a stamped component whose arms (28) are provided on the sides directed towards the contact surfaces with elastic spring elements (34) in the form of layers of rubber. USE/ADVANTAGE - Brake booster having reduced actuation noise while maintaining the required response and release times.
