Abstract: A hand brake lever, especially for a motor vehicle, includes at least two tubes (2, 3) telescopically inserted into each other for actuating a locking device (5) of a parking brake. The tubes (2, 3) automatically lock in any pulled-out position and actuation of a device corresponding to the tubes (2, 3) causes the release of the locking device (5).

Abstract: A drum brake device prevents shoe clearance over-adjustment by using a thermo-sensitive member with a lower leg opening force and provides a smaller thermo-sensitive member with a lower cost. A portion between both ends of the brake lever (50) in a direction of crossing the shoe return inhibitor (61) engages with one end of the shoe return inhibitor (61) automatically restricting the return position of the pair of brake shoes (20) and (30); the proximate portion (50a) of the brake lever (50) is pivotally supported on the brake shoe (20); and the free end (50b) of the brake lever (50) is supported at an end nipple (54) of a brake cable (52) via the thermo-sensitive member (73).

A barrier is movably disposed within the chamber so as to divide at least a portion of the chamber into a pressure compartment and a control compartment each having a volume, the volume of the pressure compartment and the control compartment each being adjustable based on movement of the barrier. A first compressible gas is disposed within the pressure compartment while a first hydraulic fluid is disposed within the control compartment A piston shaft has a first end slidably disposed within the control compartment. A temperature compensator disposed within the chamber automatically adjusts the combined volume of the pressure compartment and the control compartment based on the temperature of the first hydraulic fluid within the control compartment so as to regulate the pressure within the control compartment.

Abstract: In a vehicle dynamics control (VDC) system for a four-wheel-drive vehicle employing a brake control system regulating braking forces applied to road wheels independently of each other and a differential mechanism controlling a differential motion between front and rear wheel axles, a VDC controller controls a braking force of each road wheel depending on whether the vehicle is in oversteering or understeering. The VDC controller includes a braking-force compensation section that compensates for a braking force of at least one of a first wheel, which is subjected to vehicle dynamics control, and a second wheel to which a transferred braking force is transferred from the first wheel through the differential mechanism, to reduce a braking force of the second wheel and to prevent the braking force of the second wheel from exceeding a lateral grip limit of the second wheel during the vehicle dynamics control.

Abstract: A device used for controlling brake fluid pressure includes a plunger pump, for pressurizing brake fluid, and a drive motor for driving the plunger pump. The plunger pump and the output shaft of the drive motor are coupled together so as to transmit power through a cam mechanism arranged in a motor cam chamber. The motor cam chamber is provided with a communication passageway to allow brake fluid seepage to flow from the motor cam chamber to an interior chamber such as a solenoid chamber and/or one or more spring-enclosing chambers. The motor cam chamber is sealed from the exterior and brake fluid seeping into the motor cam chamber is contained within the interior of the device used for controlling brake fluid pressure.

Abstract: A parking brake system uses a pneumatically controlled brake actuator to provide both service and parking brake functions. The parking brake system for a vehicle includes a hand control that is manually movable between a plurality of operational positions. A valve is responsive to movement of the hand control and controls air flow from a parking brake air supply to the pneumatically controlled brake actuator. The valve includes a gate that defines the plurality of operational positions, which include a park position, a release position, and an off position. When the hand control is moved out of the off position and into the park position, the pneumatically controlled brake actuator remains pressurized and a latching mechanism is activated to mechanically lock the vehicle brake. When the hand control is moved to the release position, the vehicle brakes are re-applied to unload the latching mechanism.

Abstract: A brake system with an integral proximity sensor for providing an indication of a condition of the brake system. The brake system includes a brake drum, a brake shoe, a brake pad, and a position sensor. The brake pad is connected to a pad mounting surface of the brake shoe. The brake pad and brake shoe are movable from a disengaged position, where the brake pad is spaced apart from the brake drum to an engaged position, where the pad is in forcible engagement with the brake drum. The position sensor is coupled to the brake shoe for sensing the position of the brake shoe with respect to the position sensor. The position of the brake shoe with respect to the position sensor provides an indication of one or more conditions of the brake system.

Abstract: An oscillation limiting mechanism (4) is integrally provided to an engine mount (3) (a vibration proof mount device) of a power plant (P) mounted on an automobile in a traverse mount fashion. Not only is a stopper metal member (40) in the shape of an inverted U letter disposed so as to cross over a mount body portion (30), but a stopper rubber (42) is formed so that it protrudes from the rear end of a casing of the mount body portion (30) toward the rear side of the vehicle body. Not only is a hollow portion (43) formed in the interior of the stopper rubber (42), but a metal core body (44) is also embedded in the stopper rubber (42) so as to be revolvable around an axis in the vehicle body traverse direction as if it were a link.

Abstract: A device for clamping a rod to stop axial and/or rotative movement between the rod and the device. The device includes pressure and clamp units, the clamp unit having a bushing fixed therein and provided with a radially resilient center section normally sized to permit movement of the rod therein. The pressure unit has an actuating piston normally held under fluid pressure in one position but movable under spring pressure toward a second position should the fluid pressure be lost or released. Such movement results in the application of pressure to the bushing to radially deflect its center section inwardly into clamping engagement with the rod to stop its movement. The center section remains clamped on the rod until sufficient fluid pressure is applied to the actuating piston to move it back to its first position thus permitting radial expansion of the center section to release the rod for movement.

Abstract: An adjustable brake is provided that applies a braking force directly to an elevator sheave over which a cable suspends an elevator car and a counterweight. The brake includes a pair of calipers that apply a braking force to either longitudinal end of the sheave. The brake is spring set and may be released using, for example, electromagnetic, hydraulic or pneumatic forces. The calipers are mounted to and movable along a rail to enable adjustment of the location of the calipers. Further, the calipers are coupled together using one or more pins and are movable along the pins to enable adjustment of spacing between the calipers. The brake is particularly adapted for use with existing elevators because the brake does not require modification to the existing elevator sheave.

Abstract: In order to facilitate assembly and disassembly of a vehicle, the invention provides a method of assembling and disassembly a drum brake (1). In this assembly and disassembly method, the operating spacing of two brake shoes (4 and 5) inside a drum brake (3) is pre-adjusted. The invention makes it possible for the drum brake (1) to be delivered with the brake shoes (4 and 5) in a position where they are clamped against each other, corresponding to assembly clearance, while potentially retaining the spacing needed to match the operating clearance of the drum brake. A single action (A, B) on the hand-brake lever (6) enables the shoes to be moved from assembly clearance to operating clearance.
