ABSTRACT:
An auxiliary mechanism for an auto brake system, the mechanism includes a power cylinder, the interior of the power cylinder has a power piston and drive unit for pushing-up the power piston. A rectangular case body is joined to the rear end of the power cylinder and its interior has a rotational cam unit. An inductive unit including several on/off switches that are located on the power cylinder and a power box for driving said cam unit are provided. When oil pressure is transmitted into the power cylinder, the inductive unit will conduct the circuit and drive the cam unit to rotate for pushing-up the drive unit permitting the power piston to provide a boosting and pressure retaining function for each brake branch pump in order to achieve effective braking.
