A first valve module (4000) includes a valve block and circuits for controlling hydraulic pressure to parking brake and differential lock actuation circuits of a vehicle. An extension flowpath (4010) has an extension inlet and outlet opening respectively through an interface surface and further external surface of the valve block. A second module (1000) may be connected to supply a first service brake circuit, the circuits of the first module, and, via a second service brake outlet communicating with the extension inlet, a second service brake circuit. In a method, first and second valve blocks with internal flowpaths formed respectively by machining and by casting are assembled together with valves to define valve modules (4000, 1000) having respective, first and second functional circuits. The first valve block includes an extension flowpath. The second module supplies pressure to the first functional circuit and the extension flowpath of the first module.

The actuating device for a vehicle brake system comprises a force input member, which can be coupled to a brake pedal, and a brake master cylinder. The brake master cylinder has at least one force transmission member. The force transmission member is coupled to the force input member in an articulating fashion. The force transmission member is positioned to transmit a force, which has been exerted onto the force input member, to the brake master cylinder. The actuating device has at least one elastically deformable positioning element. The at least one positioning element produces a holding force with which the at least one positioning element holds the at least one force input member in an installation position relative to the brake master cylinder.

A hydraulic control system for control of a hydraulic motor. The hydraulic control system comprises a fluid distribution assembly having a tank, a pump to pump fluid from the tank and a directional valve for distributing pressurised fluid from the pump and to return fluid to the tank; a valve assembly fluidly connected to the directional valve, the valve assembly having a first overcenter valve and a pressure reducing valve wherein a first main line connects the directional valve to the first overcenter valve and wherein a shuttle line connects the pressure reducing valve to the first main line; a hydraulic motor fluidly connected to the valve assembly wherein the first main line connects the hydraulic motor to the first overcenter valve; and a brake assembly fluidly connected to the pressure reducing valve, wherein a drain line connects the pressure reducing valve to the hydraulic motor.

A hydraulic system of an industrial vehicle includes an oil tank in which hydraulic oil is retained; a hydraulic pump that draws in the hydraulic oil from the tank and supply the oil to a loading actuator and a brake unit; a brake valve that controls the hydraulic oil to be supplied to the brake unit according to an operation of a brake operation tool; a hydraulic oil cooler that cools the hydraulic oil; a cooling passage that allows the hydraulic oil to flow toward the cooler and further allows the oil cooled in the cooler to flow toward the brake unit; and a switching valve that switches between a first oil passage that cuts off a supply of the hydraulic oil from the hydraulic pump to the cooling passage and a second oil passage that allows the supply of the hydraulic oil from the hydraulic pump to the cooling passage.

A powered axle for a work vehicle with a dual wheel arrangement includes an axle housing, an axle hub mounted to the axle housing, and an output hub having opposite axial ends supported by one or more wheel bearings for rotation about the axle hub along a rotation axis. An electric drive is disposed, at least in part, within the axle housing, and a hub gear set is disposed, at least in part, within the axle hub and configured to transmit power from the electric drive to the output hub for rotation of the dual wheel arrangement. A wheel brake disposed radially between the axle hub and the output hub and axially between the ends of the output hub is configured to selectively permit and arrest rotation of the output hub.

A brake system includes first and second wheel brakes, a reservoir, and a brake pedal unit having a housing and a pair of output pistons slidably disposed in the housing. The output pistons generate brake actuating pressure during a manual push-through mode for actuating the first and second wheel brakes. The system further includes a plunger assembly having a housing having first and second ports, a motor driving an actuator, and a piston connected to the actuator. The piston pressurizes a first chamber when the piston is moving in a first direction to provide fluid flow out of the first port. The piston pressurizes a second chamber when the piston is moving in a second direction opposite the first direction to provide fluid flow out of the second port. The first and second ports are selectively in fluid communication with the wheel brakes.
