| 摘要 |
The invention relates to a pneumatic wheel brake for a vehicle, wherein the wheel brake has at least one brake lever (11) that can be operated by a compressed air cylinder (10) and a brake application device (20) that can be operated by the brake lever (11), wherein by means of said brake application device a first brake element (1) can be pressed against a second brake element (2) when the brake lever (11) is operated, and the wheel brake has an actuating device (3) that can be driven by an electric motor, wherein by means of said actuating device force can be applied to at least parts (7, 8, 9) of the brake application device (20), at least when the brake lever (11) is not operated, and thereby the first brake element (1) can he pressed against the second brake element (2). Furthermore, the wheel brake has a spring accuator element (4), which is arranged outside the compressed air cylinder (10), wherein force can be applied to the spring accumulator element (4) by the actuating device (3) that can be driven by, an electric motor and force can be applied to at least parts (7, 8, 9) of the brake application device (20) by the spring accumulator element, at least when the brake lever (11) is not operated, and thereby the first brake element (1) can be pressed against the second brake element (2). |
