Description

Technical Field

[0001] This utility model relates to the field of disc brake technology, specifically a heavy-duty truck disc brake. Background Technology

[0002] Heavy-duty truck disc brakes are generally pneumatic disc brakes, also known as air-operated disc brakes. They are commonly used braking systems on heavy vehicles such as trucks, buses, and commercial vehicles. Their function is similar to that of traditional hydraulic disc brakes, but they use compressed air instead of hydraulic oil to transmit force and apply braking. The working principle of a pneumatic brake is to input pressurized gas into the air tank of the pneumatic brake, thereby pushing the piston to move linearly. This causes the friction pads of the brake to press against the brake wheel, thereby generating friction and braking. The pneumatic brake is connected by air pressure. The disc slides along the axial direction by air pressure, contacting the friction plate. The disc, friction plate, etc., are assembled onto the wheel hub to form an integrated structure. The pneumatic brake is installed on the shaft using a wedge-shaped conical bushing. The heat generated by friction is dissipated by cooling fins installed on the disc on the wheel hub.

[0003] In the use of heavy-duty truck disc brakes, there is usually only one set of calipers on the outside of a brake disc for braking. Due to the large inertia of heavy-duty trucks during driving, a single set of brake calipers cannot provide adequate braking. Secondly, the brake pads, which play a braking role, will reduce in thickness after prolonged use, increasing the distance between the brake pads and the brake disc and reducing the braking effect. Finally, replacing or repairing the brake pads is relatively troublesome, requiring the disassembly of the entire caliper structure. Therefore, a heavy-duty truck disc brake is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a heavy-duty truck disc brake to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heavy-duty truck disc brake includes a brake disc and a caliper. A connecting plate is fixedly connected between the calipers. One side of the caliper has a U-shaped fixing hole, and threaded holes are provided on both sides of the fixing hole on the same side. A pneumatic push rod is engaged inside the fixing hole. A fixing plate, perpendicular to the pneumatic push rod, is fixedly connected to the outside of the pneumatic push rod. The output end of the pneumatic push rod has a threaded groove, and an adjusting bolt is threadedly connected inside the threaded groove. A positioning nut is threadedly connected to the outside of the adjusting bolt. A brake pad is fixedly connected to one end of the adjusting bolt. A perforated plate is fixedly connected to the other side of the caliper. A connection port is provided on the outside of the pneumatic push rod, and an air pipe is provided inside the connection port. A fixing rod is fixedly connected to one side of the connecting plate.

[0007] Preferably, the caliper has two symmetrically arranged fixing holes on one side, and a caliper has four fixing holes, with two holes forming a group.

[0008] Preferably, the connecting plate and the perforated plate are arranged symmetrically between the two calipers.

[0009] Preferably, one of the pneumatic push rods has two fixing plates on both sides. When the pneumatic push rod is locked inside the fixing hole, the centers of the circular hole and the threaded hole on the fixing plate are on a straight line.

[0010] Preferably, the brake pad and the perforated plate are rotatably connected.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting calipers, connecting plates and perforated plates, two sets of symmetrically arranged braking devices can be set on the outside of the brake disc, providing more braking force for heavy trucks and preventing accidents caused by poor braking effect;

[0013] 2. In this utility model, by using the threaded groove, adjusting bolt, positioning nut and brake pad, the distance between the brake pad and the brake disc can be adjusted when the brake pad has worn out after a long period of use, resulting in an excessive distance between the brake pad and the brake disc, thus ensuring a better braking effect.

[0014] 3. In this utility model, the fixed hole, threaded hole, pneumatic push rod and fixed plate can be set to facilitate quick and easy removal of the pneumatic push rod and brake pad from the caliper when the braking effect of the heavy truck is poor or the structure such as the start push rod and brake pad is damaged and needs to be replaced, thus reducing the difficulty of maintenance.

[0023] A heavy-duty truck disc brake includes a brake disc 1 and a caliper 2. A connecting plate 3 is fixedly connected between the calipers 2. A U-shaped fixing hole 4 is provided on one side of the caliper 2. Threaded holes 5 are provided on both sides of the fixing hole 4 on one side of the caliper 2. A pneumatic push rod 6 is engaged inside the fixing hole 4. A fixing plate 7, perpendicular to the pneumatic push rod 6, is fixedly connected to the outside of the pneumatic push rod 6. A threaded groove 8 is provided at the output end of the pneumatic push rod 6. An adjusting bolt 9 is threadedly connected inside the threaded groove 8.

An air pipe 14 is provided inside the connecting port 13. A fixing rod 15 is fixedly connected to one side of the connecting plate 3.

[0024] The caliper 2 has two symmetrically arranged fixing holes 4 on one side, and four fixing holes 4 on one caliper 2, with two holes forming a group; the connecting plate 3 and the hole plate 12 are symmetrically arranged between the two calipers 2; a pneumatic push rod 6 has two fixing plates 7 on both sides, and when the pneumatic push rod 6 is locked inside the fixing hole 4, the center of the round hole on the fixing plate 7 and the center of the threaded hole 5 are on a straight line; the brake pad 11 and the hole plate 12 are rotatably connected.

[0025] Working Process: This device is a disc brake for heavy-duty trucks, typically a pneumatic disc brake. Compressed air is supplied to the braking device from the truck's air tank. The brake disc 1 is fixed to one side of the wheel hub or on the rotating shaft, rotating with the wheel hub. The entire braking device is fixed to a suitable position on the heavy-duty truck by a fixing rod 15. A connecting plate 3 is fixedly connected to one side of the caliper 2, and the fixing rod 15 is fixed to the outside of the connecting plate 3. A perforated plate 12 is fixedly connected to the other side of the caliper 2. A fixing hole 4 is provided on one side of the caliper 2, and threaded holes 5 are provided on both sides of the fixing hole 4. The pneumatic push rod 6 can be engaged inside the fixing hole 4. The round hole on the fixing plate 7 coincides with the threaded hole 5, and the pneumatic push rod 6 can be fixed inside the fixing hole 4 by bolts. A threaded groove 8 is provided at the output end of the pneumatic push rod 6, and an adjusting bolt 9 is threadedly connected inside the threaded groove 8. A positioning nut 10 is threadedly connected to the outside of the adjusting bolt 9. A brake pad 11 is fixedly connected to one end of the adjusting bolt 9. A connection port 13 is provided on the outside of the pneumatic push rod 6. Pipe 14 is connected to connector 13. The other end of air pipe 14 is connected to the air source of the heavy truck. When using this brake, the heavy truck driver presses the brake pedal, and the air source provides compressed air to the pneumatic push rod 6 through air pipe 14. Under the action of pneumatic push rod 6, brake pad 11 moves towards brake disc 1. The brake pads 11 on both sides of brake disc 1 clamp the brake disc 1, thus achieving the braking effect. After the brake pads 11 have been used for a long time, the gap between the brake pads 11 and brake disc 1 becomes large. The positioning nut 10 can be loosened, and then the adjusting bolt 9 can be adjusted to bring the brake pads 11 closer to brake disc 1. Then, the positioning nut 10 is tightened to fix the adjusting bolt 9, preventing the adjusting bolt 9 from moving during the use of the heavy truck. When the brake pads 11 are worn and need to be replaced, the bolts fixing the fixing plate 7 can be loosened, and the pneumatic push rod 6 and brake pads 11 and other components can be removed as a whole for replacement of the brake pads 11, reducing the difficulty of replacing the brake pads 11 and the difficulty of debugging after installation.
