Abstract: When a leak occurs in one service circuit of a multi-circuit braking system, the leak can prevent replenishing the non-leaking service reservoir. To address this problem, a shared backup reservoir can be used to replenish the non-leaking service reservoir. A valve can be used to allow flow from the backup reservoir to whichever service reservoir is under higher pressure, as low pressure would indicate a leak. Additional valve(s) can be used to impede flow from the service reservoirs to the backup reservoir to prevent the service reservoirs from being drained if the backup reservoir is subject to a leak.

Abstract: A valve module is provided for enabling a vehicle to control an autonomous event of the vehicle. The valve module comprises a relay valve, a first solenoid valve, and a second solenoid valve. A first control pressure can be delivered through the first solenoid valve and applied to a control port of the relay valve. In one embodiment, a second control pressure can be delivered through the second solenoid valve and combined with the first control pressure. The combined first and second control pressures are applied to the control port of the relay valve.

Abstract: A valve includes at least one of an electrical port adapted to receive an electronic control signal and a pneumatic control port adapted to receive a pneumatic control signal. The valve also includes a pneumatic delivery port. The pneumatic delivery port is adapted to transmit a pneumatic fluid, based on the at least one of the received electronic control signal and the received pneumatic control signal, from a second independent source to control i) a second associated service brake and ii) delivery of the pneumatic fluid from a first independent source to control a first associated service brake.

Abstract: Various embodiments of a heat-exchange dryer apparatus are disclosed. In one embodiment, a heat-exchange dryer apparatus includes a desiccant cartridge comprising desiccant material, a purge-air reservoir secured to the desiccant cartridge, and a compressed-air conduit disposed inside the purge-air reservoir. In another embodiment, a vehicle air-brake system includes an air compressor, a desiccant cartridge comprising desiccant material, and a heat exchange dryer apparatus disposed between the compressor and the desiccant. The temperature of the compressed air is decreased while the temperature of the purge air is increased and the desiccant adsorbs a greater amount of contaminants form the compressed air for improved drying.

Abstract: A dual-control electro-pneumatic foot brake system and method are provided for use with a vehicle having multiple foot brake modules that communicate electronic signals to an electronic brake controller. As a backup feature in case there is a problem with the electron braking system, one of the foot brake modules provides pneumatic pressure to the other foot brake module, which supplies the provided pneumatic pressure to various components of the vehicle's braking system. Other alternatives are provided.

Abstract: A system for controlling a wheel brake on an auxiliary axle of a vehicle includes an electro-pneumatic drive axle brake control valve that deliver fluid pressure from a fluid source to a drive axle wheel brake on a drive axle of the vehicle responsive to an electronic control signal. An auxiliary axle brake control valve delivers fluid pressure from the electro-pneumatic drive axle brake control valve to an auxiliary axle wheel brake on the auxiliary axle of the vehicle responsive to a fluid pressure control signal. A fluid control signal generating valve generates the fluid pressure control signal responsive to a command to apply a steer axle wheel brake on a steer axle of the vehicle.

Abstract: A wheel speed sensor assembly includes a sensor having a housing configured to be received within a bore in a mounting block such that the sensor is spaced from, and faces, an exciter ring and senses rotation of the exciter ring. The housing extends along a longitudinal axis and defines a key on a radially outer surface having first and second portions having different heights. The first portion is configured to be received within a first keyway that is formed in the mounting block and is in communication with the bore in the mounting block. A clamping sleeve is configured to secure the sensor within the bore in the mounting block. The clamping sleeve defines a bore configured to receive the housing of the sensor and a second keyway in communication with the bore in the clamping sleeve. The second portion of the key is received within the second keyway.
