The present application relates to a piston assembly for engaging two selectively engageable parts. The piston assembly has a housing defining a piston cylinder and a piston. The assembly also has a piston stroke limiter. The piston stroke limiter is configured to limit the length of a return stroke of the piston from an extended stroke position and a retracted stroke position. A crushable body acts between the piston and the piston stroke limiter and is arranged to reduce in axial length when a length of an extended stroke exceeds a length of a retraction stroke to maintain the length of the return stroke.

A vehicle includes an engine, a front frame, a rear frame, an intermediate frame, a front propeller shaft, a rear propeller shaft, and a wet oiling brake. A pair of right and left front lower arms are swingably mounted to the front frame. A pair of right and left rear lower arms are swingably mounted to the rear frame. The intermediate frame is located between the front frame and the rear frame. The front propeller shaft extends forward from the engine and the rear propeller shaft extends rearward from the engine. The wet oiling brake is located within a region defined by the intermediate frame in the front-rear direction and brakes a rotation of the front propeller shaft.

The present invention relates to a clutch arrangement (500) of a vehicle transmission arrangement (100), the clutch arrangement (500) being positioned within a clutch bell housing (206) of the vehicle transmission and comprising a pneumatically controlled actuator arrangement (208) connectable to a first clutch unit (202) of the vehicle transmission arrangement (100) and arranged to controllably position the first clutch unit (202) between a closed position and an opened position, a pneumatically controlled brake actuator arrangement (210) connectable to a second clutch unit (204) of the transmission arrangement and arranged to controllably position the second clutch unit (204) between a closed position and an opened position, and a valve unit (302) connected to the pneumatically controlled actuator arrangement (208) and the pneumatically controlled brake actuator arrangement (210), wherein the valve unit (302) comprises a clutch valve (308) arranged in fluid communication with the pneumatically controlled actuator arrangement (210) for controlling supply of compressed air to the pneumatically controlled actuator arrangement (210), and a brake valve (318) arranged in fluid communication with the pneumatically controlled brake actuator arrangement (210) for controlling supply of compressed air to the pneumatically controlled brake actuator arrangement (210).

A brake device, configured to be installed directly on a driving axle or through a hub, wherein said device includes a first brake disc joined to the axle sharing rotary motion, a first container disc and a second container disc configured to be moved in the axial direction of said axle. The container discs are positioned on each side of the brake disc, such that both are configured to be moved in the axial direction towards the linings of the first brake disc and to exert a pushing pressure thereon, producing the braking of the brake disc and, therefore, of the driving axle whereon it is assembled. Furthermore, the container discs comprise an inner circuit configured to accommodate the passage of a coolant configured to cool them.

In some examples, a brake system includes a piston configured to cause a compression of a disc stack. The piston includes a piston body configured to compress a cap face of a piston cap against a pressure plate to cause the compression of the disc stack. The cap face may define a convex surface. The piston cap may be configured such that the convex surface reduces it curvature when the cap face is compressed against the pressure plate. In examples, the piston cap is configured to elastically deform to cause the cap face to reduce the curvature when the cap face is compressed against the pressure plate.

A wet friction disc includes a friction surface and a lubrication groove through which a lubricant supplied to the friction surface flows. The lubrication groove has a plurality of circumferential groove portions that extends in a circumferential direction and a plurality of intersecting groove portions that extends in directions intersecting the circumferential direction. At least one of the circumferential groove portions has a through-hole that extends through the wet friction disc between an opposite surface facing s mating member and a surface on the opposite side in an axial direction.
