Abstract
Description
Technical Field
[0001] This utility model relates to the field of brake technology, and in particular to a self-heating wet brake. Background Technology
[0002] Currently, wet brakes are widely used in engineering machinery, agricultural machinery and heavy vehicles due to their high braking performance and good heat dissipation capabilities. However, with the continuous improvement of vehicle performance and the increasing complexity of the working environment, wet brakes still face many challenges in terms of heat dissipation.
[0003] During vehicle operation, wet brakes generate braking force through friction, which generates a large amount of heat. If this heat cannot be dissipated effectively and in a timely manner, it will lead to excessively high brake temperatures, resulting in decreased braking performance, accelerated wear of brake pads, and even serious consequences such as brake failure. Traditional wet brake cooling methods mainly rely on the natural heat dissipation of the brake housing and airflow during vehicle operation. However, these methods are often insufficient to meet the cooling requirements under extreme conditions such as high temperature, high load, or continuous braking.
[0004] To address these issues, we propose a self-cooling wet brake, developing a simple, efficient, and reliable self-cooling wet brake. Utility Model Content
[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a self-heating wet brake.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A self-cooling wet brake includes: a brake, a brake assembly mounted on one side of the outer wall of the brake, a drive shaft driven in the middle of the brake, a first gear fixedly mounted on one end of the outer wall of the drive shaft, a heat dissipation and cooling mechanism driven in one side of the first gear, and a dustproof assembly mounted on the outside of the heat dissipation and cooling mechanism.
[0008] Preferably, the heat dissipation and cooling mechanism includes a second gear meshing with the first gear, a third gear meshing on both sides of the second gear, a fourth gear meshing on the other end of both sets of the third gear, and fan blades fixedly installed on the central shaft of the second gear and the two sets of fourth gears, which can dissipate heat from the brake.
[0009] Preferably, the airflow direction of the three sets of fan blades is from the outside towards the brake, and the three sets of fan blades correspond to the bottom of the brake side wall, which can continuously cool the bottom of the brake.
[0010] Preferably, the braking assembly includes a brake caliper snapped onto one side of the top of the brake, oil guide pipes connected to both ends of the sidewall of the brake caliper, and a hydraulic workstation connected to the other end of the two sets of oil guide pipes, which can clamp the brake.
[0011] Preferably, the dustproof assembly includes an outer cover installed on the outside of the three sets of fan blades, an air guide cover installed in the middle of the side wall of the outer cover, and multiple sets of equidistant air guide slots opened on the top of the air guide cover. The side wall of the outer cover is fixedly installed to the vehicle body by a bracket, which has a good dustproof effect.
[0012] Preferably, a connecting groove is provided in the middle of the inner side of the outer cover. The connecting groove is distributed between the first gear and the second gear, so that the first gear and the second gear can mesh.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In this invention, when a vehicle is in motion, the brakes are just rubbing against the friction pads, generating high stability. The transmission shaft on the vehicle drives the first gear to rotate, and the second gear meshing with the first gear rotates. Since a third gear is meshed between the two adjacent sets of second and fourth gears, it can not only synchronously drive the fan blades mounted on one side of the two sets of fourth gears to rotate, thus cooling the brake surface, but also ensure that the three sets of fan blades rotate in the same direction, allowing the three sets of fan blades to cool the brake synchronously, further improving the cooling efficiency.
[0015] An air guide shroud is installed through the middle of the outer cover side wall, and multiple sets of equidistant air guide slots are opened on the top of the air guide shroud. When the three sets of fan blades blow air to cool the brake at the same time, they will deliver negative pressure to the inside of the outer cover. In conjunction with the air guide shroud installed on one side of the outer cover, and the multiple sets of air guide slots on the top of the air guide shroud, the outside air can be introduced into the outer cover to cool the brake. The multiple sets of air guide slots are distributed on the top of the air guide shroud so that the introduced air is far away from the ground, avoiding dust and impurities on the road surface from entering the outer cover.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-3 A self-cooling wet brake includes: a brake 1, a brake assembly mounted on one side of the outer wall of the brake 1, a drive shaft 13 mounted in the middle of the brake 1, a first gear 14 fixedly mounted on one end of the outer wall of the drive shaft 13, a cooling mechanism mounted on one side of the first gear 14, a dustproof assembly mounted on the outside of the cooling mechanism, and the cooling mechanism including a second gear 21 meshing with the first gear 14, third gears 22 meshing on both sides of the second gear 21, fourth gears 23 meshing on the other ends of both sets of third gears 22, and fan blades 24 fixedly mounted on the central shaft of the second gear 21 and the two sets of fourth gears 23, which can dissipate heat from the brake 1. The airflow direction of the three sets of fan blades 24 is from... Facing the brake 1, the three sets of fan blades 24 correspond to the bottom of the side wall of the brake 1, continuously cooling the bottom of the brake 1. When the vehicle is in motion, the brake 1 is just rubbing against the friction pads, generating high stability. The drive shaft 13 on the vehicle drives the first gear 14 to rotate, and the second gear 21 meshing with the first gear 14 rotates. Since the third gear 22 meshes between the two adjacent sets of second gears 21 and the fourth gear 23, it can not only synchronously drive the fan blades 24 mounted on one side of the two sets of fourth gears 23 to rotate, cooling the surface of the brake 1, but also make the three sets of fan blades 24 rotate in the same direction, so that the three sets of fan blades 24 synchronously cool the brake 1, further improving the cooling efficiency.
[0022] Furthermore, the dustproof component includes an outer cover 2 installed on the outside of the three sets of fan blades 24, an air guide shroud 3 connected and installed in the middle of the side wall of the outer cover 2, and multiple sets of equidistantly distributed air guide slots 31 opened on the top of the air guide shroud 3. The side wall of the outer cover 2 is fixedly installed to the vehicle body by a bracket, which has a good dustproof effect. When the three sets of fan blades 24 blow air to cool the brake 1 simultaneously, they will deliver negative pressure to the inside of the outer cover 2. In conjunction with the air guide shroud 3 connected and installed on one side of the outer cover 2, and the multiple sets of air guide slots 31 opened on the top of the air guide shroud 3, the outside air can be introduced into the interior of the outer cover 2 to cool the brake 1. The multiple sets of air guide slots 31 are distributed on the top of the air guide shroud 3 so that the introduced air is far away from the ground, avoiding dust and impurities on the road surface from entering the interior of the outer cover 2.
[0023] Furthermore, a connecting groove 32 is provided in the middle of the inner side of the outer cover 2. The connecting groove 32 is distributed between the first gear 14 and the second gear 21, which can make the first gear 14 and the second gear 21 mesh. When the transmission shaft 13 drives the first gear 14 to rotate, the first gear 14 and the second gear 21 can mesh in conjunction with the connecting groove 32 provided in the inner side of the outer cover 2.
[0024] Furthermore, the braking assembly includes a brake caliper 11 snapped onto one side of the top of the brake 1, oil guide pipes 12 connected to both ends of the side wall of the brake caliper 11, and a hydraulic workstation connected to the other end of the two sets of oil guide pipes 12. The hydraulic workstation can clamp the brake 1, and after supplying hydraulic oil to the oil guide pipes 12 through the hydraulic workstation, it is delivered to the piston chamber of the brake caliper 1. The piston moves under the action of hydraulic pressure, pushing the friction pads to make close contact with the brake 1, generating friction force, thereby clamping the brake 1.
[0025] In operation, hydraulic oil is first supplied to the guide pipe 12 via a hydraulic workstation and then to the piston chamber of the brake caliper 11. The piston moves under hydraulic pressure, pushing the friction pads into close contact with the brake 1, generating friction to clamp the brake 1. Simultaneously, when the vehicle moves again, the brake 1, having just rubbed against the friction pads, exhibits high stability. The drive shaft 13 on the vehicle drives the first gear 14 to rotate, and the second gear 21, meshing with the first gear 14, rotates. Since a third gear 22 meshes between adjacent sets of second gears 21 and fourth gears 23, it can simultaneously drive the fan blades 24 mounted on one side of the two sets of fourth gears 23 to rotate, cooling the surface of the brake 1. Furthermore, the three sets of fan blades 24 can rotate in the same direction, allowing them to cool the brake 1 synchronously, further improving cooling efficiency. At the same time, an air guide shroud 3 is installed through the middle of the side wall of the outer cover 2, and multiple sets of equidistant air guide slots 31 are opened on the top of the air guide shroud 3. When the three sets of fan blades 24 blow air to cool the brake 1 synchronously, they will deliver negative pressure to the inside of the outer cover 2. In conjunction with the air guide shroud 3 installed through one side of the outer cover 2, and the multiple sets of air guide slots 31 on the top of the air guide shroud 3, outside air can be introduced into the interior of the outer cover 2 to cool the brake 1. Moreover, the multiple sets of air guide slots 31 are distributed on the top of the air guide shroud 3, so that the introduced air is far away from the ground, preventing dust and impurities on the road from entering the interior of the outer cover 2.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
