Description

Technical Field

[0001] The utility model relates to the technical field of disc brakes, in particular to a self-locking disc brake. Background Art

[0002] Automobile disc brakes are also called disc brakes. They are generally controlled by hydraulics. The main components include the master cylinder, brake caliper, oil pipe, etc. The brake disc is made of alloy steel and fixed to the wheel. It rotates with the wheel, and its rotation is controlled by the brake caliper.

[0003] After searching, the publication (announcement) number: CN220523141U discloses a self-locking disc brake, which relates to the technical field of disc brakes. The technical scheme is as follows: it comprises a brake disc, a plurality of connecting columns are fixedly arranged inside the brake disc, a brake caliper disc is sleeved outside the brake disc, two limiting grooves are arranged at the bottom of the brake caliper disc, a self-locking component is arranged at the bottom of the brake caliper disc, the self-locking component comprises a connecting cover, the connecting cover is arranged at the bottom of the brake caliper disc, an electromagnet is fixedly arranged inside the connecting cover, and a power line is fixedly connected to the top of the electromagnet. The beneficial effect of a self-locking disc brake is as follows: the electromagnet loses its magnetic force by power failure, and the elastic force of the extended spring resets the movable block, and the reset of the movable block drives the clamping block to buckle on the outside of the connecting column. When the brake disc rotates, the connecting column pushes the clamping block, and the clamping block contacts the bottom of the brake caliper disc, so that the clamping block is blocked by the brake caliper disc and cannot move, thereby blocking the rotation of the brake disc, thereby achieving the purpose of self-locking the brake disc.

[0004] Although the above scheme loses its magnetic force when the electromagnet is powered off, thus blocking the rotation of the brake disc and achieving the purpose of self-locking the brake disc, the brake disc is blocked by buckling the block on the outside of the connecting column. When the car is running fast and the brake disc rotates too fast, it is easy to cause collision damage to the block under the action of inertia, resulting in a decrease in braking effect. For this reason, we propose a self-locking disc brake. Utility Model Content

[0005] The main purpose of the utility model is to provide a self-locking disc brake, which solves the problem of a brake unit and a cooling unit by setting.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A self-locking disc brake comprises a main body unit, a brake unit and a cooling unit arranged on the side of the main body unit, wherein the cooling unit is located on one side of the brake unit;

[0008] The brake unit comprises a connection seat mounted on the side wall of the main unit, an electromagnet mounted on the side of the connection seat, and a brake member arranged at the end of the electromagnet;

[0009] The cooling unit comprises an extrusion water tank and an electric telescopic rod installed on the side of the main unit, and an extrusion plate installed at the telescopic end of the electric telescopic rod, and the extrusion end of the extrusion water tank is adjacent to the extrusion plate.

[0010] Preferably, the main body unit includes a brake disc, a brake caliper disc disposed above the brake disc, and a connecting disc installed on a side of the brake disc.

[0011] Preferably, the main unit further comprises a heat dissipation hole installed on a side of the connection plate.

[0012] Preferably, the brake member comprises a connecting spring installed at an end adjacent to the electromagnet and the brake disc, a friction plate installed at an end of the connecting spring, and a magnetic block installed at an end adjacent to the friction plate and the electromagnet.

[0014] Preferably, there are two groups of the integral structure consisting of the braking unit and the cooling unit, and the two groups of the integral structure consisting of the braking unit and the cooling unit are symmetrically arranged with respect to the brake disc.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, by providing a brake unit and a cooling unit, when the brake disc needs to be self-locked, the electromagnet is powered off and loses its magnetism. At this time, under the elastic force of the connecting spring, the friction plate drives the magnetic block away from the electromagnet and abuts against the brake disc until the brake disc is blocked and self-locked, thereby realizing convenient self-locking of the brake disc, avoiding collision damage to the card under the action of inertia when the speed of the brake disc is too high, and improving the braking effect; when the brake disc needs to be rotated, the telescopic end of the electric telescopic rod is extended, and the extrusion plate squeezes the extrusion end of the extrusion water tank, so that the water in the extrusion water tank is sprayed toward the brake disc, thereby avoiding excessively high temperature of the brake disc when the friction plate rubs against the brake disc, and improving the service life of the brake disc.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Example

When the electromagnet 202 is energized to generate magnetism, it can generate magnetic attraction to the brake member 203;

[0029] like Figure 1 As shown, the main unit 1 includes a brake disc 101, a brake caliper disc 102 arranged above the brake disc 101, and a connecting disc 103 installed on the side of the brake disc 101. The arrangement of the brake caliper disc 102 facilitates blocking braking of the brake disc 101.

[0030] like Figure 4 As shown, the main unit 1 further includes a heat dissipation hole 104 installed on the side of the connecting plate 103 . The arrangement of the heat dissipation hole 104 prevents the brake disc 101 from being able to dissipate heat quickly when in contact with the friction plate 2032 .

[0031] like Figure 5As shown, the brake member 203 includes a connecting spring 2031 installed at the adjacent end of the electromagnet 202 and the brake disc 101, a friction plate 2032 installed at the end of the connecting spring 2031, and a magnetic block 2033 installed at the adjacent end of the friction plate 2032 and the electromagnet 202. The setting of the connecting spring 2031 allows the friction plate 2032 to always fit with the brake disc 101, thereby avoiding the friction plate 2032 from failing to fit tightly with the brake disc 101 after being worn.

[0032] like Figure 5 As shown, the cooling unit 3 further includes a water spray nozzle 304 installed on the side wall of the squeeze water tank 301 adjacent to the brake disc 101 . The arrangement of the water spray nozzle 304 facilitates the water in the squeeze water tank 301 to be sprayed out.

[0034] When the brake disc 101 needs to be self-locked, the electromagnet 202 is powered off and loses its magnetism. At this time, under the elastic force of the connecting spring 2031, the friction plate 2032 drives the magnetic block 2033 away from the electromagnet 202 and abuts against the brake disc 101 until the brake disc 101 is blocked and self-locked, thereby realizing convenient self-locking of the brake disc 101, avoiding collision damage to the card due to inertia when the speed of the brake disc 101 is too high, and improving the braking effect. Example

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, a self-locking disc brake comprises a main body unit 1, a brake unit 2 and a cooling unit 3 arranged at the side of the main body unit 1, and the cooling unit 3 is located at one side of the brake unit 2;

When the telescopic end of the electric telescopic rod 302 is extended, it can drive the extrusion plate 303 to extrude the extrusion water tank 301.

[0038] like Figure 1 As shown, the main unit 1 includes a brake disc 101, a brake caliper disc 102 arranged above the brake disc 101, and a connecting disc 103 installed on the side of the brake disc 101.

[0039] like Figure 4 As shown, the main unit 1 further includes a heat dissipation hole 104 installed on the side of the connecting plate 103 . The arrangement of the heat dissipation hole 104 prevents the brake disc 101 from being able to dissipate heat quickly when in contact with the friction plate 2032 .

[0040] like Figure 5 As shown, the brake member 203 includes a connecting spring 2031 installed at the adjacent end of the electromagnet 202 and the brake disc 101, a friction plate 2032 installed at the end of the connecting spring 2031, and a magnetic block 2033 installed at the adjacent end of the friction plate 2032 and the electromagnet 202. The setting of the connecting spring 2031 allows the friction plate 2032 to always fit with the brake disc 101, thereby avoiding the friction plate 2032 from failing to fit tightly with the brake disc 101 after being worn.

[0043] When the brake disc 101 needs to rotate, the telescopic end of the electric telescopic rod 302 is extended, and the extrusion plate 303 squeezes the extrusion end of the extrusion water tank 301, so that the water in the extrusion water tank 301 is sprayed toward the brake disc 101, thereby avoiding the brake disc 101 from overheating when the friction plate 2032 rubs against the brake disc 101, thereby improving the service life of the brake disc 101.
