Description

Technical Field

[0001] The utility model relates to the technical field of brake shoes, in particular to a highly wear-resistant brake shoe for heavy trucks. Background Art

[0002] Drum brakes have the characteristics of strong braking force, low production cost and convenient subsequent maintenance. They are widely used in trucks and low-end family cars. For large heavy trucks, due to their heavy weight and large inertia, the braking safety components need to bear huge torque during driving, and the strength requirements of their braking system are relatively high.

[0003] The existing drum brake uses a driving mechanism to drive the brake shoe to expand outward, and the brake pad and the brake drum rub to achieve the braking effect. However, the existing brake shoe is prone to slight deformation during long-term high-load use, which drives the brake pad to deform together, affecting the friction area between the brake pad and the brake drum. Excessive deformation of the brake shoe will aggravate the wear and even damage of the brake pad, affecting driving safety. Therefore, a highly wear-resistant heavy-duty truck brake shoe is proposed. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a highly wear-resistant heavy-duty truck brake shoe, which can maintain good strength and ensure braking performance under long-term high-load use, thereby improving the practicality of the brake shoe.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a highly wear-resistant heavy-duty truck brake shoe, comprising a brake shoe, a rib plate is welded and fixed at the bottom of the brake shoe, a reinforcing plate is fixedly installed on the bottom surface of the brake shoe, the reinforcing plate has the same surface area as the bottom surface of the brake shoe, the reinforcing plate is clamped and fixed to the rib plate, a plurality of equidistantly distributed reinforcing ribs are provided on the bottom surface of the brake shoe, and the reinforcing ribs are clamped and fixed to the reinforcing plate.

[0006] Preferably, the reinforcing plate includes a center plate and side plates, an integrally formed connecting plate is provided at the connection between the center plate and the side plates, the center plate, the side plates and the connecting plate are surrounded to form a mounting groove, and the rib plate is clamped in the mounting groove.

[0007] Preferably, mounting holes are provided at the connection points between the two ends of the rib plate and the brake shoe, and the connecting plate is clamped and fixed in the mounting holes.

[0008] Preferably, a plurality of equally spaced snap-in grooves are formed through the middle of the center plate, and the reinforcing ribs are snap-fitted and fixed in the snap-in grooves.

[0009] Preferably, a plurality of evenly distributed first through holes are formed through both sides of the brake shoe, and a plurality of evenly distributed second through holes are formed through the side plate, and the positions of the second through holes correspond to those of the first through holes.

[0010] Preferably, the brake shoe and rib plate are made of high-quality carbon structural steel and are quenched, and the reinforcement plate is made of carbon fiber.

[0011] Preferably, the surface of the brake shoe is electroplated with a protective layer, and the protective layer is a corrosion-resistant layer.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] 1. The reinforcing plate and reinforcing ribs are arranged on the brake shoe to improve the strength of the brake shoe and prevent the brake shoe from deforming under high-load conditions. The reinforcing plate abuts against the bottom surface of the brake shoe to counteract the force of the brake shoe deformation, further preventing the brake shoe from deforming and affecting the friction of the brake pad, thereby ensuring the braking effect and improving the practicality of the brake shoe.

[0014] 2. By making the brake shoe and rib plate of high-quality carbon structural steel, which has high strength itself, after quenching, the brake shoe and rib plate have good wear resistance. In actual use, the service life is longer and more stable, further improving the practicality of the brake shoe. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is attached to the instruction manual Figure 1-2 , the technical solution of the utility model is explained through specific embodiments.

[0019] Embodiment:

[0020] like Figure 1As shown, the utility model provides a highly wear-resistant heavy-duty truck brake shoe, including a brake shoe 1, a rib plate 2 is welded and fixed at the bottom of the brake shoe 1, a reinforcing plate 3 is fixedly installed on the bottom surface of the brake shoe 1, the reinforcing plate 3 is equal to the bottom surface area of ​​the brake shoe 1, the reinforcing plate 3 is clamped and fixed to the rib plate 2, and a plurality of equidistantly distributed reinforcing ribs 4 are provided on the bottom surface of the brake shoe 1, and the reinforcing ribs 4 are clamped and fixed to the reinforcing plate 3.

[0021] like Figure 2 As shown, a plurality of evenly distributed first through holes 11 are formed on both sides of the brake shoe 1, the reinforcing plate 3 comprises a central plate 31 and a side plate 32, an integrally formed connecting plate 33 is provided at the connection between the central plate 31 and the side plate 32, the central plate 31, the side plate 32 and the connecting plate 33 enclose a mounting groove 34, a plurality of evenly distributed clamping grooves 311 are formed at the middle of the central plate 31, the reinforcing rib 4 is clamped and fixed in the clamping groove 311, a plurality of evenly distributed second through holes 321 are formed on the side plate 32, the second through holes 321 correspond to the first through holes 11, mounting holes 21 are provided at the connection between the two ends of the rib plate 2 and the brake shoe 1, the rib plate 2 is clamped in the mounting groove 34, and the connecting plate 33 is clamped and fixed in the mounting hole 21.

[0022] It should be noted that, in the present embodiment, the brake shoe 1 and the rib plate 2 are both made of high-quality carbon structural steel, and both are quenched, and the reinforcing plate 3 is made of carbon fiber.

[0023] The surface of the brake shoe 1 is electroplated with a protective layer, which is a corrosion-resistant layer.

[0024] Assembly steps: first, electroplate a protective layer on the surface of the brake shoe 1, then weld the reinforcing rib 4 on the bottom surface of the brake shoe 1, fit the reinforcing plate 3 on the bottom surface of the brake shoe 1, and make the reinforcing rib 4 snap into the snap-in groove 311 on the reinforcing plate 3, align the first through hole 11 with the second through hole 321, snap the rib plate 2 into the mounting groove 34, make the rib plate 2 fit with the bottom surface of the brake shoe 1, weld the brake shoe 1 and the rib plate 2, and snap the mounting hole 21 on the rib plate 2 on the connecting plate 33, weld and fix the brake shoe 1 and the rib plate 2, place the corresponding brake pad on the surface of the brake shoe 1, insert rivets into the second through hole 321 and the first through hole 11, rivet the brake pad and the brake shoe together, and complete the assembly of the brake shoe.

[0025] Working principle: reinforcing ribs 4 are arranged on the bottom surface of the brake shoe 1, and a reinforcing plate 3 is arranged between the brake shoe 1 and the rib plate 2. The brake shoe 1 and the reinforcing plate 3 are connected into one by the rib plate 2 and the rivets for fixing the brake pad, so as to increase the thickness of the brake shoe 1. The reinforcing plate 3 cooperates with the reinforcing ribs 4 to reinforce the brake shoe 1. The existence of the reinforcing ribs 4 makes the brake shoe 1 not easy to deform. The setting of the reinforcing plate 3 can resist the deformation force of the brake shoe 1 when the brake shoe 1 is deformed, so as to prevent the brake shoe 1 from deforming, thereby ensuring the normal use of the brake shoe 1. The brake shoe 1 and the rib plate 2 are high-quality carbon structural steel, which has good strength itself. After quenching treatment, its wear resistance is improved, and it can still maintain good performance in a long-term high-load use environment. The reinforcing plate 3 is carbon fiber with high hardness to resist the deformation pressure of the brake shoe 1. A corrosion-resistant layer is electroplated on the surface of the brake shoe 1 to prevent the brake shoe 1 from being corroded, so as to improve the service life of the brake shoe.
