摘要: A traveling vehicle includes a mechanical brake link mechanism to transmit operation of a brake pedal to a brake device housed in a case and to control brakes of right and left rear wheels. The brake link mechanism includes a pair of brake rods extending in a front-back direction at sides of the case. A guard assembly includes a pair of guards extending in the front-back direction below the pair of brake rods. The pair of brake rods overlaps the pair of guards in a vertical direction. In a side view of the traveling vehicle, the pair of brake rods includes a higher portion positioned above a lower surface of the case to be distanced by a predetermined interval or more and positioned above the lower surface of the case, and a lower portion positioned below the higher portion. The pair of guards overlaps at least all of the lower portions in the vertical direction.

摘要: A hydraulic unit and an electromagnetic unit are disposed such that a piston rod of the hydraulic unit and a solenoid shaft of the electromagnetic unit are orthogonal to each other. The electromagnetic unit is configured such that an end surface of an expanded diameter portion of a shaft portion of the solenoid shaft on the piston rod side is pressed against an attracting portion of a yoke by the elastic force of a spring when a parking unlocked state is established by a hydraulic pressure.

摘要: The utility model provides a hand brake system used on a non-beam pumping unit, including a drive mechanism mounted at the lower part of the pumping unit and an actuator mounted on a side of the main drive sprocket of the pumping unit, and the drive mechanism and the actuator are connected by a wire rope. In the utility model, the drive mechanism and actuator of the brake system are separately arranged, thus ensuring promptness of braking and eliminating the potential safety hazard of workers falling from a height. The braking mode of the existing brake system on a pumping unit is to achieve the braking function by locking the rotary shaft from the outer side. The braking force upon braking is relatively small and the braking reliability is relatively poor.

摘要: The invention relates to an operating apparatus for a brake, having an actuator unit with a linearly mobile actuator element, an actuating unit with a linearly mobile actuating element by means of which a braking element can be moved relative to a brake disc or a brake drum, and a transmission unit for transmitting a force from the actuator element to the actuating element. The transmission unit has a deflection device by means of which the force which is transmitted from the actuator element to the actuating element can be deflected from a first direction into a second direction.

摘要: An actuator (1), especially for a motor vehicle parking brake has a telescopic device (2) that actuates a brake cable (6), and a drive unit which is equipped with an electromechanical drive for actuating the telescopic device (2). The actuator (1) further has a displacement sensor unit for detecting the actuating travel of the telescopic device (2) as well as a force sensor unit for detecting the force applied to the brake cable (6) by the drive unit. The displacement sensor unit and the force sensor unit are disposed next to each other in or on the housing (3) of the telescopic device (2) while being separated from the brake cable (6). The assembly has a particularly simple and compact design while reducing the constructive and mounting effort required during the production of the actuator.
