<p>A braking device for driving axle includes a motor end cap (7), a piston (30), a large friction plate (21), a primary friction device, a secondary friction device and a planetary reducer (5). The piston (30) is installed axially in the motor end cap (7). The primary friction device is mated with the secondary friction device. The motor end cap (7) is fixed to the planetary reducer (5). A first pressure disc (19) is sleeved with piston (30). A second pressure disc (22) and the large friction plate (21) are engaged in the planetary reducer (5) through the teeth provided on the flange thereof. A fixed disc (16) is axially fixed in the inner gear ring of the planetary reducer (5). The braking device integrates the driving braking system and the parking braking system, so the structure is simple and reliable.</p> |
