  • Patent number: 6955406
    Abstract: The invented apparatus is designed for use with a tow vehicle and trailer combination. The apparatus comprises a controller, a vacuum supply sensor, and a sensor unit used to measure the barometric pressure and/or elevation of the current location of the tow vehicle/trailer combination. Using information from the sensor unit, the controller determines a vacuum pump activation level and/or deactivation level appropriate for the ambient pressure in which the apparatus is operating. By monitoring the signal supplied by the vacuum supply sensor and by operating a vacuum pump switch signal, the controller maintains a supply of vacuum between the activation and deactivation levels. In this manner, the controller can compensate for changes in local conditions so as to operate the vacuum pump in an efficient manner while maintaining an adequate supply of vacuum for operation of the trailer brake system.

  • Patent number: 6951372
    Abstract: The adaptive brake application and initial skid detection system allows rapid brake application and prevents deep initial skids. Brake pressure is compared with a predetermined threshold brake pressure. Wheel velocity error signals are also generated to indicated the difference between the wheel velocity and a reference velocity signal. A pressure bias modulator integrator responsive to brake pressure signals adjusts the wheel velocity error signals to provide an anti-skid control signal. The pressure bias modulator integrator can also be initialized to the value of the measured brake pressure when the wheel velocity error signals indicate the beginning of a skid. Brake pressure difference signals are generated to indicate the difference between brake pressure and a commanded brake pressure, and an adjusted brake pressure error signal is generated in response to the brake pressure difference signals.

  • Patent number: 6942202
    Abstract: The invention disclosed is a compact and lightweight hybrid pneumatic-magnetic isolator-actuator capable of large force, substantial stroke and bandwidth actuation with near frictionless operation and vibration isolation with very low break frequency. Pneumatic and magnetic forces are applied to a single carriage comprised primarily of a coaxially arranged air piston and coil. The carriage is driven relative to a frame or housing including an internally mounted cylindrical piston sleeve and magnetic actuator body. A combination of air bearings and air bearing piston construction provide for frictionless motion of the carriage relative to the frame. The pneumatic piston provides the actuation force for both static loads and low frequency dynamic loads. An integrally mounted sensor and control unit determine the pressure error resulting at the pneumatic piston.

  • Patent number: 6942201
    Abstract: A vehicle air spring assembly having a pair of spaced end members which sealingly engage a flexible bladder to form an internal air chamber having an internal volume. One of the end members is a bead plate which has an annular outer end portion which is crimped to the bladder to provide an air tight seal therebetween. The end plate has a recessed portion located between the outer end portion which projects into the air chamber to reduce the volume of the air chamber to change the spring characteristic of the air spring. A plurality of reinforcing gussets extend between the recessed portion of the bead plate and a surrounding upstanding wall which extends between the outer end portion and recessed portion to enable the bead plate to be clamped by fasteners against an adjacent vehicle component and resist deformation when subjected to internal pressure.

  • Patent number: 6942072
    Abstract: A motor assembly, such as an electro-mechanical-brake (EMB) motor assembly includes an electric motor, a latch gear, a solenoid, and a spring. The latch gear is non-rotatably attached to the drive shaft of the motor. The spring is operatively connected to the solenoid and has a spring projection which is longitudinally-deflectable by energizing the solenoid. The gear tooth is shaped to longitudinally retain the spring projection when the latch gear rotates the gear tooth into engagement with the longitudinally-deflected spring projection. In one example, the latch gear is a parking-brake latch gear and the motor assembly provides a parking brake function for an EMB electric motor which also is used for applying and releasing a vehicle's driving brakes.
