A central release mechanism for a pneumatic clutch actuating device has a cylinder housing, which, about a central axis, delimits a ring-shaped pressure chamber wherein a ring-shaped piston which can be pneumatically pressurized via the pressure chamber and which is operatively connectable to a clutch is guided so as to be displaceable along the central axis. In the pressure chamber, between the ring-shaped piston and a base of the cylinder housing, a preload spring arrangement braces the ring-shaped piston and the cylinder housing apart from one another. A movement of the ring-shaped piston relative to the cylinder housing is detectable with a sensor arrangement which has a position detector and a position encoder. The preload spring arrangement has a multiplicity of distributed preload springs, angularly spaced apart from one another, about the central axis. Between the preload springs as viewed in a circumferential direction about the central axis, at least a part of the sensor arrangement is arranged in the region of the pressure chamber providing a compact construction.

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 pressure generator for a hydraulic power braking system. The pressure generator is designed to have a ball thread drive and a planetary gear, a spindle nut of the ball thread drive forming a planetary carrier for planetary wheels of the planetary gear. A sun wheel is non-rotatably fixed to a hollow shaft of an electric hollow shaft motor and together with the hollow shaft rotatably supported. The electric hollow shaft motor surrounds the ball thread drive and the planetary gear.

A hydraulic disc brake for a vehicle. The disc brake comprises a service brake arrangement configured to actuate under hydraulic pressure to urge a brake pad towards a rotor to apply the disc brake during a braking operation; a parking brake arrangement configured to urge the brake pad towards the rotor to apply the disc brake during a parking operation, wherein the parking brake arrangement has an applied condition and a released condition; and a parking brake indicator configured to indicate whether the parking brake arrangement is in the applied condition or the released condition.

A disc brake including a piston driving mechanism. The piston driving mechanism includes an input member extended in a cylinder in a protruding direction of a piston, including a threaded portion formed on a circumferential surface of the input member, and configured to be rotated with transmission of torque from an electric motor; a tubular rotation linear motion member including an engaging threaded portion that is engaged with the threaded portion of the input member, and configured to move in an axial direction of the cylinder by rotation of the input member to transmit a torque of the electric motor to the piston; a tubular support member supported on a caliper main body to be not rotatable and placed on an outer side in a radial direction with respect to the rotation linear motion member; and a rolling element placed between the support member and the rotation linear motion member.

A parking brake for a vehicle includes an electric brake motor, a transmission, and a brake piston. The transmission transfers a drive movement of the motor to the brake piston. The transmission has a transmission efficiency that steadily increases as a temperature in the transmission rises.

A disc brake for a commercial vehicle has a brake caliper spanning a brake disc on the vehicle side, in which brake caliper a clamping device is arranged which has a pivotable brake lever engaging in at least one bridge carrying a brake plunger, which at the same time is directly or indirectly supported at the inner side of a wall of the brake caliper. The contact area of the bridge at the brake lever or of the brake lever at the brake caliper is configured as a pivot bearing having a bearing shell cross-sectionally configured as an arc forming a part of the pivot bearing. The bearing shell is placed in a seating. The disc brake is configured such that the bearing shell is located in the pivoting direction of the brake lever with its opposite longitudinal borders at stop edges, which longitudinally limit the trough-shaped seating.

A method for operating a vehicle brake, wherein the vehicle brake comprises a service brake having an actuating piston, which can be moved into an actuation position in order to produce a braking force by the action of a hydraulic pressure, and wherein the vehicle brake also comprises a parking brake unit, which is designed to move over a first motion range without producing a braking force and is also designed to move over a second motion range, in which the parking brake unit is supported against the actuating piston and a braking force is thus changed, wherein the first and second motion ranges transition into each other at a support point, wherein the method is performed in the pressureless state or at a hydraulic pressure below a predefined threshold value and comprises the following steps: a) moving the parking brake unit from the first into the second motion range or vice versa; b) recording the curve of an operating parameter of the parking brake unit during step a); and c) determining the position of the support point on the basis of the curve of the operating parameter.

A hydraulic power take-off is provided for use with industrial drives that deliver power to industrial equipment. The hydraulic power take-off has a brake disconnect system that can manually release a brake assembly to allow low-effort rotating of the industrial equipment components to facilitate servicing.

A wet brake includes a housing, non-rotatable brake discs, rotatable brake discs, a parking lever, a piston, a plate, and a connector. The non-rotatable and the rotatable brake discs are disposed in engagement with the housing and an outer peripheral surface of a rotary shaft, respectively. The piston, the plate, and the rotary shaft are accommodated in the housing. The piston is configured to be pushed by the parking lever toward the non-rotatable and the rotatable brake discs. The plate is in contact with one of the non-rotatable brake discs or one of the rotatable brake discs. The connector is disposed at a position between the piston and the plate. The housing has a recess that is formed in an outer peripheral surface of the housing at a position corresponding to the position of the connector. An outer diameter of the connector is smaller than that of the piston.
