Brake booster

Abstract

A brake booster having an input element (20) for actuating the brake booster is described. The input element (20) at its end facing a brake pedal has a receiving sleeve (20A) for an actuating rod (34), which is to be coupled to the brake pedal. Disposed inside the receiving sleeve (20A) is a spring sleeve (36) comprising at least one spring element (36C, 36D), which cooperates with the actuating rod (34) when the latter is brought into a detent position in relation to the input element (20). The spring element (36C, 36D) extends substantially in axial direction and is actuable in a spring-elastic manner in a radially outward direction. The spring sleeve (36) at its brake pedal-side end has a radially outwardly extending portion (36F), which is fastened by means of a bead (20D) of the receiving sleeve (20A) to the receiving sleeve (20A).
