Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle parts, in particular to an integrated heat-insulating motorcycle caliper. Background Technique

[0002] Motorcycle braking is mainly achieved by the cooperation of a caliper and a brake disc. During braking, a large amount of heat is generated due to the friction of the brake pads. Therefore, heat insulation needs to be set to protect the normal operation of core components such as pistons. After retrieval, the patent with the Chinese patent publication number CN221097264U discloses an integrated heat-insulating motorcycle caliper. When the caliper brakes, by installing a heat-insulating sheet between the brake pad and the piston, the piston and the brake pad are completely isolated from each other, so that it does not conduct to the piston and the caliper, playing a better protective role. However, the piston is still directly connected to the heat-insulating sheet, resulting in the heat of the heat-insulating sheet being able to be transferred to the piston. In the case of long-term and frequent braking, the high temperature of the brake pad will be transferred to the heat-insulating sheet. Since the heat-insulating sheet and the piston always remain connected, the heat-insulating sheet will heat the piston for a long time, and then the piston will still gradually and rapidly heat up. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides an integrated heat-insulating motorcycle caliper, which solves the problem that the existing caliper heat-insulating sheet in the background art still remains connected to the piston, resulting in the temperature of the heat-insulating sheet being continuously transferred to the piston, causing the piston to gradually and rapidly heat up.

[0004] To achieve the above objectives, the utility model is realized through the following technical solutions: An integrated heat-insulating motorcycle caliper includes a caliper body, a slide rod, a heat-insulating sheet, and a piston. The inside of the caliper body is of a hollow structure, and a connection port is provided on one side of the caliper body. The connection port is communicated with the inside of the caliper body. The inner cavities on both sides of the caliper body are filled with hydraulic oil, and the inner cavities on both sides of the caliper body are communicated with each other through a connecting pipe. A slide rod is provided inside the caliper body. A spring is sleeved outside the slide rod. The spring is arranged between two heat-insulating sheets. The outside of the slide rod is slidably connected to the heat-insulating sheet. A brake pad is fixedly installed on one side of the heat-insulating sheet. Four pistons are provided inside the caliper body. The pistons are slidably connected to the inside of the caliper body.

[0005] Preferably, there are two slide rods. Limit blocks are welded at both ends of the two slide rods. One side surface of the limit block is closely attached to the surface of the heat-insulating sheet. The limit block is beneficial to limit the sliding stroke of the heat-insulating sheet and prevent the heat-insulating sheet from contacting the piston when resetting.

[0006] Preferably, two ventilation grooves are formed at both ends of the caliper body. The ventilation grooves are aligned with the heat insulation sheet, and the surfaces on both sides at one end port of the ventilation groove are arc-shaped. The arc-shaped structure is beneficial to increasing the air inlet area of the ventilation groove, improving the air flow velocity at one end of the air outlet, and enhancing the heat dissipation effect.

[0007] Preferably, two hole grooves matching the cross-sectional shape of the sliding rod are formed at the top of the heat insulation sheet, and the heat insulation sheet is made of insulating mica material. The insulating mica material enables the heat insulation sheet to have a high heat insulation effect and reduces the influence of heat on the piston.

[0008] Preferably, heat dissipation grooves are formed on the other side of the heat insulation sheet. The heat dissipation grooves are arranged in a straight line at equal intervals, and there is a gap between the heat dissipation grooves and the piston. The provision of multiple heat dissipation grooves is beneficial to increasing the heat dissipation surface on one side of the heat insulation sheet.

[0009] Preferably, when the piston is in the extended state, the end surface is in close contact with the surface of the heat dissipation groove, and the brake pad is in close contact with the motorcycle brake disc, which is beneficial to ensuring that the brake pad can contact and clamp the brake disc to brake when the piston is in the extended state.

[0010] The present utility model provides an integrated heat-insulating motorcycle caliper, which has the following beneficial effects:

[0011] (1) For the integrated heat-insulating motorcycle caliper, when braking, hydraulic oil will enter the internal cavity of the caliper body, and then push the piston to move outwards, so that the piston will contact the heat dissipation groove, and then push the brake pad to contact the motorcycle brake disc, thus achieving the braking effect. When braking stops, the hydraulic oil will be discharged from the inside of the caliper body, and then drive the piston to contract inwards, so that the piston can separate from the heat dissipation groove. At the same time, under the action of the spring, the heat insulation sheet will be pushed to slide to both sides through the sliding rod, thus realizing the reset of the heat insulation sheet. Due to the existence of the limit block, a gap can be maintained between the heat dissipation groove and the piston, which is beneficial to preventing the heat of the heat insulation sheet from being transferred to the piston.

[0012] (2) For the integrated heat-insulating motorcycle caliper, when the motorcycle is moving, the airflow will enter the ventilation groove through the ventilation grooves at both ends of the caliper body, and then the high-speed flowing airflow will blow towards the brake pad and the heat insulation sheet through the other end of the ventilation groove, thus dissipating heat from the heat insulation sheet and the brake pad, which is beneficial to achieving a rapid cooling effect. At the same time, the heat dissipation grooves on one side of the heat insulation sheet are beneficial to increasing the heat dissipation surface of the heat insulation sheet, which is beneficial to further improving the heat dissipation effect.

[0013] Therefore, the problem that the existing heat insulation sheet of the caliper is still connected to the piston, which will cause the temperature of the heat insulation sheet to continuously be transferred to the piston, resulting in the piston gradually heating up rapidly, is solved.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-5, an embodiment of the present utility model provides a technical solution: an integrated heat-insulating motorcycle caliper, which includes a caliper body 1, a slide rod 4, a heat-insulating sheet 5, and a piston 8. The inside of the caliper body 1 is of a hollow structure, and a connection port 2 is provided on one side of the caliper body 1. The connection port 2 is communicated with the inside of the caliper body 1. The inner cavities on both sides of the caliper body 1 are filled with hydraulic oil, and the inner cavities on both sides of the caliper body 1 are communicated with each other through a connecting pipe 3. A slide rod 4 is provided inside the caliper body 1. A spring 11 is sleeved outside the slide rod 4. The spring 11 is arranged between two heat-insulating sheets 5. The outside of the slide rod 4 is slidably connected with the heat-insulating sheet 5. A brake pad 6 is fixedly installed on one side of the heat-insulating sheet 5. Four pistons 8 are provided inside the caliper body 1. The pistons 8 are slidably connected with the inside of the caliper body 1. There are two slide rods 4. Limit blocks 9 are welded at both ends of the two slide rods 4. One side surface of the limit block 9 is in close contact with the surface of the heat-insulating sheet 5. When braking stops after braking, the hydraulic oil will be discharged from the inside of the caliper body 1, thereby driving the pistons 8 to contract inward, so that the pistons 8 can be separated from the heat dissipation grooves 7. At the same time, under the action of the spring 11, the heat-insulating sheet 5 will be pushed to slide to both sides through the slide rod 4, thereby realizing the reset of the heat-insulating sheet 5. Due to the existence of the limit block 9, a gap can be maintained between the heat dissipation groove 7 and the piston 8, which is beneficial to avoiding the heat transfer of the heat-insulating sheet 5 to the piston 8.

[0022] Embodiment 2: Two ventilation grooves 10 are respectively opened at both ends of the caliper body 1. The ventilation grooves 10 are aligned with the heat-insulating sheets 5. The two sides of the port at one end of the ventilation groove 10 are in an arc shape. Two hole grooves matching the cross-sectional shape of the slide rod 4 are opened at the top of the heat-insulating sheet 5. The heat-insulating sheet 5 is made of insulating mica material. A heat dissipation groove 7 is opened on the other side of the heat-insulating sheet 5. The heat dissipation grooves 7 are arranged in a straight line at equal intervals. There is a gap between the heat dissipation grooves 7 and the pistons 8. When the motorcycle is moving, the air flow will enter the inside of the ventilation groove 10 through the ventilation grooves 10 at both ends of the caliper body 1. Then the high-speed flowing air flow will blow towards the brake pad 6 and the heat-insulating sheet 5 through the other end of the ventilation groove 10, thereby dissipating heat from the heat-insulating sheet 5 and the brake pad 6, which is beneficial to achieving a rapid cooling effect. At the same time, the heat dissipation grooves 7 on one side of the heat-insulating sheet 5 are beneficial to increasing the heat dissipation surface of the heat-insulating sheet 5, which is beneficial to further improving the heat dissipation effect.

[0023] Working principle: When the caliper brakes, the hydraulic oil will enter the internal cavity of the caliper body 1, and then push the piston 8 to move outward. As a result, the piston 8 will come into contact with the heat dissipation grooves 7, and then push the brake pads 6 into contact with the motorcycle brake disc, thus achieving the braking effect. When braking stops, the hydraulic oil will be discharged from the inside of the caliper body 1, and then drive the piston 8 to contract inward, so that the piston 8 can separate from the heat dissipation grooves 7. At the same time, under the action of the spring 11, the heat insulation sheet 5 will be pushed to slide on both sides through the slide rod 4, thus realizing the reset of the heat insulation sheet 5. Due to the existence of the limit block 9, a gap can be maintained between the heat dissipation grooves 7 and the piston 8, which is beneficial to preventing the heat of the heat insulation sheet 5 from being transferred to the piston 8, thus achieving a good heat insulation effect.
