A work vehicle is disclosed that includes an elastic support mechanism for supporting an exhaust muffler. The elastic support mechanism includes a support platform member, an elastic cylindrical members and an bar-shaped member. The support platform member is supported by a rear-linking frame bar to adjust a position of the support platform member along one of lateral and longitudinal directions of the body frame. An elastic cylindrical member supported by one of the support platform member and the exhaust muffler. The elastic cylindrical member has an axis extending along the other of the lateral and longitudinal directions, and is supported at a single position, in a direction of the axis, of said one of the support platform member and the exhaust muffler. A bar-shaped member supported by the other of the support platform member and the exhaust muffler is fitted into the elastic cylindrical member to be supported by the elastic cylindrical member.

A hydraulic power take-off is provided for use with industrial drives. The hydraulic power take-off has a multiple-force brake system that facilitates actively slowing large inertial loads associated with a heavy rotating mass of an industrial machine. The multiple-force brake system applies different braking forces at different times to control deceleration of the heavy rotating mass in the industrial machine to reduce its stopping time. The multiple-force brake system may include a clutch assembly and a brake assembly. A control system may control the clutch and brake assemblies to provide the multiple-force brake system a relatively higher energy brake engagement state and a relatively lower energy brake engagement. This may include alternating between the higher and lower energy brake engagement states to pulse between high and low pressure braking to facilitate cooling of the system while slowing the large inertial loads.

A brake piston includes a piston pocket. The piston pocket receives a nut that is axially moveable along a center axis. The nut is restricted from rotating within the piston pocket when a torque due to a frictional engagement between a nut seal and an inner pocket wall, one or more projections, or both is greater than an it torque at the nut. The nut is rotatable within the piston pocket when a torque due to the frictional engagement between the nut seal and the inner pocket wall, the one or more projections or both is less than the input torque at the nut and is less than the torque due to the frictional engagement between the piston and the piston seal.

An object of the invention is to provide a disc brake improved in reliability. In a disc brake, a first holder-side projection is formed on a holder, and a first cover-side recess that fits the first holder-side projection of the holder is formed in a cover. An elastic member is disposed between the first holder-side projection of the holder and the first cover-side recess in the cover.

A parking lock having a locking pawl engageable into a parking interlock gear, a connecting rod with an interlocking element to prevent the parking lock from disengaging when in the locked condition, a spring for engaging the parking lock, a hydraulically actuatable actuator for disengaging the parking lock, and an emergency release device for emergency disengagement of the parking lock. The piston is articulatedly connected to a first disk rotatably mounted on a selector shaft, a second disk connected to the selector shaft in a torsion-proof manner is articulatedly connected to the connecting rod, the spring is tensioned between the transmission housing and the second disk, and the emergency release device is connected to the selector shaft in a torsion-proof manner. The first disk is operatively connected to the second disk such that rotation of the second disk by the emergency release device does not rotate the first disk.

A method for maintaining a brake system in a vehicle with a hydraulic vehicle brake and an electromechanical brake device with an electric brake motor includes preparing the brake system for maintenance operations by actuating the electric brake motor to displace a transmission member into a retracted position that is remote from a brake starting position in which a brake lining is located adjacent to a brake disk of the wheel brake device. The method further includes actuating the electric brake motor to displace the transmission member in the direction of the brake starting position after completion of the maintenance operations.

An electromechanical brake actuator (100) is configured to move a service-brake rod (104) between a full-braking position (BP) and a drive position (DP). A parking-brake rod (112) is coupled to the service-brake rod and is movable between a first position (P1) for locking the service-brake rod (104) in the full-braking position (BP), and a second position (P2) where the service-brake rod (104) is free to be moved. A spring element (116) coupled to the parking-brake rod is arranged so that in a fully-compressed state (CS) the parking-brake rod is in the second position, and in a fully-released state (RS) the parking-brake rod is in the first position. A hydraulic unit (118) is operatively coupled to the parking-brake rod and configured, based on a parking-brake signal, to lock the parking-brake rod or allow a release of the spring element to the fully-released state.

An electric push rod with a dual brake mechanism includes an electric motor, a transmission device, a first brake mechanism and a second brake mechanism. The electric motor has a driving wheel. The transmission device is installed on a side of the electric motor and includes a deceleration mechanism, a lead screw, a driven wheel, and a telescopic pipe. The deceleration mechanism is disposed between the driving wheel and the driven wheel. The lead screw is sheathed with the driven wheel and the driven wheel is driven by the electric motor to rotate together with the lead screw. The telescopic pipe and the lead screw are screwed and driven. The lead screw is sheathed with the first brake mechanism formed on a side edge of the driven wheel. The lead screw is sheathed with the second brake mechanism disposed between the driven wheel and the telescopic pipe.

A brake system that includes a brake piston and a spindle. The brake piston includes a piston pocket defined in the brake piston. The piston pocket includes a threaded portion. The spindle includes a threaded portion. The threaded portion of the spindle is adapted to threadably engage the threaded portion of the piston pocket.

An illustrative example embodiment of an elevator brake device includes a brake member configured to move into a braking position to resist movement of an elevator car associated with the brake device. A plurality of actuators are associated with the brake member and selectively controllable to apply a force to cause the brake member to move into the braking position. A brake controller determines a number of the actuators to activate based on a determined load of the elevator car associated with the brake device.
