A valve arrangement (2) of a hydraulically braked tractor vehicle for controlling the brake pressure of a pneumatically braked trailer includes an electronically controlled trailer control valve (6) with an inlet valve (14), an outlet valve (16), a pneumatical relay valve (18), a breakaway valve (20) and a brake control pressure sensor (24). The valve arrangement also has a hydraulically controlled backup valve (8) with a hydraulically activated relay valve (46), a redundancy valve (48) and a hydraulic control pressure sensor (50). Output-side brake control lines (40, 76; 62, 78) are connected via a shuttle valve (10) to a brake coupling head (82). The valves (14, 16, 18, 20) and the pressure sensors (24, 50) of the trailer control valve (6), the valves (46, 48) of the backup valve (8,) and the shuttle valve (10) may be combined in one trailer control module (98) with a single housing (100).

A military vehicle includes a front axle, a rear axle, a front differential coupled to the front axle, and a transaxle coupled to the rear axle and the front differential. The transaxle includes an internal mechanical disconnect that facilitates mechanically decoupling the transaxle from the front differential.

A vehicle includes a passenger capsule having a first end and a second end, a front module coupled to the first end of the passenger capsule and including a front axle assembly, a rear module coupled to the second end of the passenger capsule and including a rear axle assembly, and a braking system. The braking system includes a pump, an actuator including a rod that extends through a brake housing to apply a biasing force to a brake and inhibit movement of the vehicle, and a line coupling the pump to the actuator. Engagement of the pump provides a pressurized fluid flow through the line that overcomes the biasing force and releases the brake.

A military vehicle includes a passenger capsule having a front end and a rear end, a front module coupled to the front end of the passenger capsule, a rear module coupled to the rear end of the passenger capsule, a generator, and an export power kit. The front module includes a front subframe, a prime mover, a front axle assembly, and a front differential coupled to the front axle assembly. The rear module includes a rear subframe, a rear axle assembly, and a transaxle coupled to the rear axle assembly, the prime mover, and the front differential. The generator is configured to be driven by the prime mover to generate electricity. The export power kit is coupled to the generator and configured to facilitate exporting power off of the military vehicle.

A vehicle includes a passenger capsule having a first end and a second end, a front module coupled to the first end of the passenger capsule and including a front axle assembly, an engine coupled to the front module, a rear module coupled to the second end of the passenger capsule and including a rear axle assembly, and a transaxle coupled to the rear module and the engine. The transaxle includes a transfercase component and a differential component contained at least partially within a housing that defines a structural component of the rear module. The rear axle assembly includes at least one of an upper control arm, a lower control arm, a spring, and a damper that is directly coupled to the transaxle.

A method of making a brake assembly. The method may include providing a brake pad carrier, an air operated brake actuator suitable for attaching to the brake pad carrier, and a hydraulically operated brake actuator suitable for attaching to the brake pad carrier, and attaching one of the air operated brake actuator and hydraulically operated brake actuator to the brake pad carrier to provide a brake assembly.

A fluid-operated braking system (1) for a tractor-trailer vehicle includes a trailer control valve (2), a parking brake module (3), and an electronic control unit (4) electrically connected to the trailer control valve (2) and to the parking brake module (3). A pressure fluid accumulator (13) of the braking system (1) is connected to a control pressure input (P43) of the trailer control valve (2). A redundancy circuit controls the control pressure input (P43), even during a malfunction of the control unit (4). The parking brake module (3) includes a control valve (14), a redundancy valve (15) and a changeover valve (16) controlled by an electronic switch unit (20) with a holding function. When the control unit (4) malfunctions, the last error-free switching position of the control valve (14) or the redundancy valve is maintained until a operationally safe resting state is reached or the ignition system is switched off.
