Pneumatic brake assistance servomotor for vehicle, has distributor with cavity delimiting surface with portion that is molded on corresponding part of surface area delimited by ball joint which is inclined with respect to servomotor`s axis

摘要

The servomotor (1) has a distributor (3) provided with a cavity (12) that delimits a surface (14) receiving a ball joint (10) of a brake control rod (9) along an axis (5) of the servomotor, where the distributor has elements (17, 18) made of plastic material and steel, respectively. The surface has a portion molded on corresponding part of a surface area (28) delimited by the joint. The joint is retained inside the cavity and is inclined with respect to the axis, where the joint is supported against the portion and a base of the cavity longitudinally with respect to the axis. An independent claim is also included for a method of mounting a brake control rod in a pneumatic brake assistance servomotor.
