MASTER CYLINDER ASSEMBLY

摘要

The assembly (10) comprises an electric motor (11) and a master cylinder (12) connected to the motor. The motor transmits drive through a ballscrew transmission (23) to a piston (70) slidable within a bore (64a) in the master cylinder (12). The transmission (23) is housed at least in part within a hollow armature (40) of the motor (11) with a portion (58d) of the transmission extending into a central bore (70e) in the piston. The location of the transmission within the armature leads to a very compact assembly.
