  • Patent number: 10704635
    Abstract: A spring assembly is provided which decreases the fatigue and wear on the springs of the assembly. The spring assembly includes upper and lower pistons separated by a substantially incompressible fluid. The lower piston is attached to one or more springs. The surface area of the upper surface of the lower piston is greater than the surface area of the lower surface of the upper piston. As such, the springs are deflected by a distance less than the distance traveled by the upper piston. By decreasing the length the springs are compressed, the springs are subject to less fatigue and wear. As a result, the life span of the springs is increased and the maintenance required of the spring assembly is minimized relative to that of typical spring assemblies.

    Abstract: A parking brake control device performs a releasing control with good precision by more precisely maintaining clearance between a friction-applying member and a friction-applied member. During a releasing control, a timing at which a braking force generated by an electric parking brake 2 drops to zero is detected based on a change in a motor current, and a second releasing operation time is set according to the magnitude of the motor current at the time the braking force drops to zero. This makes it possible for the second releasing operation time to be set in accordance with fluctuations in a motor load due to temperature changes or the like. Therefore, a clearance between a brake pad and a brake disc can be kept constant according to the motor load.

  • Patent number: 8573368
    Abstract: A parking brake actuator system for an outdoor power equipment unit, such as a riding lawn mower, comprises a reversible electric motor that drives a gear reduction assembly. The gear reduction assembly rotates an output shaft at a speed slower than the speed of rotation of the motor. The output shaft has opposite ends that are linked by a pair of actuating rods to a pair of parking brakes. As the motor is rotated in reverse rotary directions, the connecting portions of the rods that are coupled to the parking brakes are moved in opposite, straight line directions to move the parking brakes between brake disengaged and brake engaged positions.

  • Patent number: 8522934
    Abstract: A lockable piston-cylinder unit includes a cylinder having at least one axially facing counterstop; a piston dividing the cylinder into a first working chamber and a second working chamber; a piston rod extending through the first working chamber to a free end outside the cylinder; and a fastening tube having a first end in which the free end of the piston rod is fixed, a second end which receives the cylinder coaxially, and at least one axially facing supporting stop. When the piston rod is extended to maximum extension, the fastening tube is rotatable relative to the cylinder from a release position, wherein the supporting stop is offset from a respective counterstop, to a locking position, wherein the supporting stop faces the counterstop so that the fastening tube cannot move axially relative to the cylinder.

  • Patent number: 8424655
    Abstract: A brake cylinder for pneumatic vehicle brakes includes a spring brake section for parking brake actions and a service brake section for service brake actions combined in one housing. The housing is subdivided by a piston into two compartments, one compartment being used as the pressure compartment for the service brake, and the brake spring of the spring section being arranged in the other compartment on the opposite end of the piston. The brake spring acts upon an additional spring piston, which can be locked and released relative to the piston by a pneumatic locking mechanism. The spring piston is connected to a piston rod directly or via additional elements to actuate the brake. Once the locking mechanism is released, the brake spring displaces the pistons relative each other during a parking brake action. At least one pneumatic valve for controlling the brake cylinder are integrated into the brake cylinder.

  • Patent number: 8397884
    Abstract: A brake cylinder for pneumatically actuated vehicle brakes, especially for commercial vehicles, includes a housing. The housing is divided into two chambers by a piston, one of the chambers being used as a pressure chamber for actuating an operating brake section, and a cylinder spring of a spring-loaded brake section being arranged in the other chamber on the opposite side of the piston. The cylinder spring acts on another spring-loaded piston in the chamber, which can be blocked in relation to the first piston by a pneumatically actuated locking mechanism. The other spring-loaded piston is released from the first piston by a releasing action of the blocking mechanism, and is connected to a piston rod for actuating the vehicle brake. Following release of the blocking mechanism, the cylinder spring acts between the two pistons and moves them in relation to each other during a parking braking operation.
