Background
Currently, EPB equipped in automobiles is mostly based on calipers, or electronic parking brakes integrated on calipers, while EPB-Si is an electronic parking solution based on drum brakes. First, drum brakes can produce a greater braking torque than calipers (disc brakes), due to their inherent self-energizing effect (amplified friction force), and in short, the braking force is stronger. Meanwhile, the drum brake is also advantageous over the disc brake in terms of weight, and if the drum brake (two rear wheels) is adopted for one vehicle, the drum brake is lighter than the disc brake by 20% -30% to realize weight reduction of 2-3 kg. Particularly for electric vehicles, lighter weight means longer endurance mileage. In addition, compared with an open disc brake, the drum brake has a relatively closed structure, friction dust cannot be scattered everywhere, and EPB-Si is helpful for reducing PM10 and protecting environment. The closed structure also has another advantage that EPB-Si has better rust resistance than disc brake, and can avoid a series of brake noise and even insufficient brake force caused by the EPB-Si. At present, the industry is matched with the drum EPB with the leading shoe structure, and the performance using requirement of a commercial vehicle cannot be met, so that the drum brake with the bidirectional self-boosting structure is required to be matched with the EPB for use, but the problem that the parking brake of the EPB is weakened or fails due to the fact that the bidirectional self-boosting structure is of a driving automatic adjusting structure and the brake arm pulling stroke is increased after the brake lining is worn cannot be solved, so that the pulling stroke exceeds the MGU using stroke.

The first collar hoof 3 and the second collar hoof 12 are pressed on the braking bottom plate 21 through a bowl pressing mechanism, and the self-adjusting plate 7 is pressed on the first collar hoof 3 through the bowl pressing mechanism. The bowl pressing mechanism comprises a through pin 24, a pressure spring 22 is arranged on the through pin 24, the upper end of the pressure spring 22 is connected with an upper bowl pressing 8 in a pressing mode, and the lower end of the pressure spring 22 is connected with a lower bowl pressing 23 in a pressing mode. The self-adjusting plate 7 is pressed between the first collar shoe 3 and the lower pressing bowl 23. The second collar shoe 12 is connected with the brake arm 11, two ends of the parking self-adjusting supporting plate 13 are respectively connected with the first collar shoe 3, the second collar shoe 12 and the brake arm 11 in a clamping mode, one end of the parking self-adjusting tensioning spring 18 is connected with the parking self-adjusting supporting plate 13, the other end of the parking self-adjusting tensioning spring 18 is connected with the second collar shoe 12, two ends of the parking self-adjusting return spring 19 are respectively connected with the parking self-adjusting supporting plate 13 and the parking self-adjusting push plate 5, and the parking self-adjusting supporting plate 13 is connected with the parking self-adjusting push plate 5. The brake arm 11 is connected to the second collar shoe 12 via the arm pin 14 and the large catch 25. The parking self-adjusting supporting plate 13 is connected with the parking self-adjusting push plate 5 through the parking self-adjusting pin 20 and the small clip 26.
The working principle of automatic parking adjustment is as follows: the automatic parking adjustment is based on automatic driving adjustment generated when the first collar shoe 3 and the second collar shoe 12 are continuously worn in the continuous braking process of the brake drum 1, and the automatic parking adjustment is performed after the first collar shoe 3 and the second collar shoe 12 are continuously worn in a friction manner. (the parking automatic adjustment work is triggered only after the automatic adjustment of the travelling crane is met). As shown in fig. 2, after the adjusting ratchet 9 is automatically adjusted, the first and second collar shoes 3 and 12 are pushed to keep the gap with the brake drum 1 constant. Fig. 3 automatically adjusts with the driving so that the gap between the first collar shoe 3 and the parking self-adjusting push plate 5 is reduced. At this point, automatic parking adjustment is triggered. When the first collar shoe 3 moves to the left, the parking self-adjusting supporting plate 13 is kept motionless by the tension of the parking self-adjusting tensioning spring 18, the first collar shoe 3 drives the parking self-adjusting pushing plate 5 to rotate and automatically adjust by taking the parking self-adjusting pin 20 as the center, the parking self-adjusting pushing plate 5 can be limited by the tension of the parking self-adjusting return spring 19 on the parking self-adjusting pin 20 to prevent callback, the gap between the first collar shoe 3 and the parking self-adjusting pushing plate 5 is kept constant, the gap between the brake arm 11 on the second collar shoe 12 and the parking self-adjusting supporting plate 13 is constant, the working stroke of the brake arm 11 is constant, and the parking self-adjusting is completed.
The hydraulic (braking) braking process of the invention is as follows: when a driver brakes to brake, brake fluid pushes two pistons 15 of a wheel cylinder 16 to move to two sides respectively and pushes a first collar shoe 3 and a second collar shoe 12 to press a brake drum 1, and the brake drum 1 can drive the first collar shoe 3 and the second collar shoe 12 attached to the brake drum to do corresponding rotary motion under the influence of the running direction of the vehicle. At this time, the first collar shoe 3 and the supporting pin 2 generate a gap, the first collar shoe 3 transmits friction force to the second collar shoe 12 through the adjusting ratchet wheel 9, the second collar shoe 12 concentrates acting force at the supporting pin 2, and meanwhile, the self-adjusting plate 7 mounted on the second collar shoe 3 moves along with the gap generated by the first collar shoe 3 and the supporting pin 2, the self-adjusting plate 7 moves downwards by taking the upper pressing bowl 8 as a rotation center under the tensile force of the plate return spring 6, the adjusting ratchet wheel 9 is stirred to automatically adjust, and the braking gap generated by friction plate loss is adjusted. After the brake hydraulic pressure is released, the first collar shoe 3 and the second collar shoe 12 are pulled by the lower tensioning spring 10 and the upper return spring 17, the piston 15 in the wheel cylinder 16 is pushed to restore to the initial state, and the self-adjusting plate 7 is pulled by the self-adjusting return spring 6 and the limiting function of the self-adjusting support plate 4, so that the upper pressing bowl 8 can move upwards as a rotation center, and the initial position is restored to complete the automatic adjustment function of the travelling crane.
The handle braking process of the invention is as follows: the brake cable pulls the brake arm 11, the brake arm 11 takes the arm pin 14 as a rotation center to move leftwards, the parking self-adjusting support plate 13 is pushed to transfer thrust to the brake collar shoes 3 to be attached to the brake drum 1, meanwhile, as the force of the brake arm 11 to the left side is increased, the first collar shoes 3 attached to the brake drum 1 generate reaction force, the thrust is transferred to the brake arm 11 through the parking self-adjusting support plate 13, and the brake arm 11 takes the push plate 13 as a rotation center at the moment and pushes the second collar shoes 12 to be attached to the brake drum 1 through the arm pin 14 arranged on the second collar shoes 12. The brake drum 1 drives the first collar shoe 3 and the second collar shoe 12 attached to the brake drum to do corresponding rotary motion under the influence of the running direction of the vehicle. At this time, the first collar shoe 3 and the supporting pin 2 generate a gap, the first collar shoe 3 transmits friction force to the second collar shoe 12 through the adjusting ratchet wheel 9, the second collar shoe 12 concentrates acting force at the supporting pin 2, and meanwhile, the self-adjusting plate 7 mounted on the second collar shoe 3 moves along with the gap generated by the first collar shoe 3 and the supporting pin 2, the self-adjusting plate 7 moves downwards by taking the upper pressing bowl 8 as a rotation center under the tensile force of the plate return spring 6, the adjusting ratchet wheel 9 is stirred to automatically adjust, and the braking gap generated by friction plate loss is adjusted. After the brake cable is released, the first collar shoe 3 and the second collar shoe 12 are recovered to an initial state under the tension of the lower tensioning spring 10 and the upper return spring 17, the self-adjusting plate 7 is subjected to the tension of the self-adjusting return spring 6 and the limiting function of the self-adjusting support plate 4, the upper pressing bowl 8 can be moved upwards by taking the upper pressing bowl 8 as a rotation center, the parking self-adjusting support plate 13 is subjected to the tension of the parking self-adjusting tensioning spring 18, and the initial position is recovered, so that the automatic driving adjusting function is completed.
