摘要： The present invention relates to a suspension member which cooperates with a bracket, a traction bar, and a shock absorber in order to connect a wheel assembly to a vehicle frame. The suspension member comprises a sheet of metal which is deformed to receive and fixedly secure a spindle which rotatably supports a wheel assembly. The suspension member is engageable with a brake assembly to support the latter relative thereto and also opposes torque developed during braking. In a preferred embodiment the suspension member comprises a pair of metal sheets which are deformed to form mirror images of each other so that upon fastening, they support the spindle and cooperate with the brake assembly to provide braking for the wheel assembly.

摘要： In a servomotor having a first diameter piston concentric to a second diameter piston for supplying a braking system with a first pressurizing force and a second pressurizing force in response to an operator input. A transfer valve has a first face and a second face which are located on opposite sides of a radial bore in the second piston to receive a first pressurizing force. The transfer valve has an axial passageway therethrough which communicates relief or reservoir pressure to the first and second faces of the transfer valve to provide a balance pressure force on the same. A spring holds the second face of the transfer valve against a seat to prevent communication of the first pressurizing force into the relief chamber. When a predetermined first pressurizing force is obtained, the actuator in response to an operator will overcome the spring and move the second face away from the seat to allow the first pressurizing force associated with the first piston to be proportionally communicated into the relief chamber. As the first pressurizing force is communicated into the relief chamber, the output from the servomotor is transferred to the second piston to provide an additional operational or second pressurizing force to activate the wheel brakes of the vehicle.

摘要： A hold-off resilient member for resisting movement of a plunger caused by an input force. The plunger initially moves a first control valve to permit air to enter a servomotor and develop an operational pressure differential in response to the input force. Further movement of the plunger will axially compress the resilient member as a function of input force to output force causing its peripheral surface to radially expand and actuate a second control valve. The actuation of the second control valve will permit air above atmospheric pressure to develop the operational pressure differential in response to the input force.

摘要： A hold off valve for use in a two stage pressurizing mechanism to control the transition from a first operational condition to a second operational condition. A stepped piston in the pressurizing mechanism has a first diameter and a second diameter through which an input force sequentially operates a control valve to produce a first operational fluid force and a second operational fluid force in a pressurizing chamber. A relief chamber which is connected to the pressurizing chamber receives the first operational fluid force when the control valve is operated. The hold off valve retains the first operational fluid in the relief chamber until a predetermined pressure build up occurs after which the second diameter independently operates to produce the second operational fluid force.
