Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the single embodiment in the present invention, all other embodiments obtained by the ordinary skilled person in the art without creative efforts all belong to the protection scope of the present invention.
As shown in fig. 1, the utility model provides a pneumatic disc brake for heavy-duty mine car braking, including brake support 1, brake caliper 2, outside friction disc 3, inside friction disc 4, return spring 5, friction disc pressure spring 6, friction disc clamp plate 7, automatic gap adjusting mechanism 8, air chamber seal ring 9, sealing member 10, bush 11, sliding pin 12, lock bolt 13, seal shroud 14, fastener 15, spring support rod 16 and step bolt 17; the concrete structure is as follows:
an automatic gap adjusting mechanism 8 is arranged in the brake caliper body 2; when the inner friction plate 4 and the outer friction plate 3 are worn, the mechanism automatically adjusts the brake clearance according to the wear condition, so that the disc brake is always in a stable and effective state as shown in figure 1.
An air chamber sealing ring 9 is arranged on an inner cavity of the brake caliper body 2, the air chamber sealing ring 9 is in bidirectional sealing, one side seals the inner cavity of the brake caliper body 2, the other side seals an air chamber which needs to be installed by a customer, and therefore the sealing effect is improved due to the double-sealing structure.
The bush 11 has a self-lubricating function, and the sliding pin 12 can slide in the bush with less friction force; the bush 11 is pressed into the cylindrical holes at the two sides of the brake caliper body 2; the sliding pin 12 connects the brake bracket 1 with the brake caliper body 2 through the locking bolt 13; the brake bracket 1 is fixed on the bridge frame; the brake caliper body 2 slides back and forth by taking the sliding pin 12 as an axis; a sealing element 10 is arranged at the joint of the sliding pin 12 and the brake bracket 1; a sealing cover 14 is arranged at the pin hole of the brake caliper body 2, see fig. 2.
The spring support rod 16 is arranged between the outer side friction plate 3 and the inner side friction plate 4 and is fixed through a fastener 15; the return spring 5 is sleeved on the spring support rod 16. When the vehicle brakes, the inner friction plate 4 and the outer friction plate 3 clamp the brake disc on the axle to generate torque to decelerate the vehicle; when the vehicle releases the brake, the inner friction plate 4 is quickly away from the brake disc due to inertia factors; the outer friction plate 3 is slowly far away from the brake disc due to the weight of the brake caliper body 2 although the outer friction plate has inertia factors; however, the outer friction plate 3 is also quickly moved away from the brake disk by the return spring 5, which effectively prevents the inner friction plate 4 and the outer friction plate 3 from being worn differently, as shown in fig. 3.

The friction plate pressing plate groove 707 is open type, which can make the pressing plate have displacement function in the axial direction, and effectively prevent the brake caliper body 2 from tearing the step bolt 17 due to the cast stretching caused by vehicle braking. The third friction plate pressing plate hole 703, the fourth friction plate pressing plate hole 704 and the sixth friction plate pressing plate hole 706 can facilitate installation of the abrasion alarm wire harness on the vehicle no matter in any structure; the fifth friction plate pressing plate hole 705 can ensure that the wire harness protection frame 18 is fixed on the friction plate pressing plate 7 in any mode, and plays a role in protecting the abrasion alarm wire harness as shown in figure 5.
