Description

Technical Field

[0001] This utility model relates to the field of automotive brake manufacturing and processing technology, specifically to a cooling device for automotive brakes. Background Technology

[0002] Automotive brakes are a key component of a vehicle's safety system, primarily used to convert the vehicle's kinetic energy into heat energy through friction, thereby achieving deceleration or stopping. Disc brakes, in particular, use a metal disc that operates via caliper friction surfaces; this metal disc is called the brake disc. Friction elements clamp the brake disc from both sides to generate braking force. Brake discs are mostly made from castings, which require very high precision. After casting, the brake disc castings need to be cooled.

[0003] In the existing technology, brake discs are mostly cooled by one of the following methods: natural cooling, air cooling, or coolant cooling. However, natural cooling and air cooling have low cooling efficiency and uneven cooling effect. Coolant cooling can cause large temperature differences in the brake disc, and the sudden drop in temperature can easily cause internal stress, affecting product quality. Further development and improvement are needed. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for automobile brakes to solve the problems of low cooling efficiency, uneven cooling effect and large temperature difference in the existing brake disc cooling process.

[0015] Combination Figures 1 to 3The cooling device for an automotive brake, as shown, includes a workbench 1. Cooling boxes 2 are mounted at both longitudinal ends of the top of the workbench 1. A cooling pool 3 is recessed into one side of the workbench 1 on the transverse side of each cooling box 2. A sliding support beam 4 is positioned between the cooling boxes 2. Several supporting columns 5 are positioned between the bottom of the sliding support beam 4 and the top of the workbench 1. An air chamber 6 is provided inside each cooling box 2. Several air outlets 7 are equidistantly arranged on the inner surface of one longitudinal side of each cooling box 2. A fan 8 is mounted on the outer surface of the other longitudinal side. The air outlets 7 and the output ends of the fan 8 are connected to the air chamber 6. A movable support plate 9 is slidably connected to the top of the sliding support beam 4 along the transverse direction. One longitudinal end of the movable support plate 9 is connected to the sliding support beam 4. A moving mechanism 10 is provided between the support beams 4, and a lifting device 11 is provided at the top of the other end. The bottom output end of the lifting device 11 passes through the moving support plate 9 and is installed with a lifting support plate 12. A supporting rotating shaft 13 is provided at the center of the cooling pool 3 corresponding to the lifting support plate 12. A rotating motor 14 is provided on the top of the lifting support plate 12 on one side of the lifting device 11, and a guide plug-in rod 15 is provided at the other end. The output end of the rotating motor 14 is connected to one end of the top of the supporting rotating shaft 13. The guide plug-in rod 15 is plugged into the moving support plate 9. Several V-shaped bearing rods 16 are provided at equal intervals from top to bottom on the outer surface of the supporting rotating shaft 13 below the lifting support plate 12.

[0016] The sliding support beam 4 is connected to the support column 5, the support column 5 is connected to the worktable 1, and the support rotation shaft 13 is connected to the V-shaped support rod 16 by welding. This ensures the stability and firmness of the connection structure, improving safety and service life. An air distribution plate is installed inside the air cavity 6 to ensure uniform airflow from the outlet. A thermoelectric cooler is also installed on one side of the air distribution plate, with the cold end of the cooler located inside the air cavity 6 and the hot end located outside, so that a cooler airflow is blown out from the outlet 7. The brake disc undergoes initial cooling. The moving mechanism 10 is a drive motor equipped with a transmission gear. Through the transmission structure where the transmission gear meshes with the transmission rack, it enables the moving support plate 9 to perform linear reciprocating motion laterally. This allows the brake disc, placed on the V-shaped support rod 16, to move laterally between the cooling boxes 2 and above the cooling pool 3. A control device 17 is provided on one longitudinal side of the worktable 1. The fan 8, the drive motor in the moving mechanism 10, the lifting device 11, the rotary motor 14, and the semiconductor cooling chip are all electrically connected to the control device 17. This device controls the working status of the fan 8, the drive motor in the moving mechanism 10, the lifting device 11, the rotary motor 14, and the semiconductor cooling chip. The lifting device 11 is one of a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0017] In use, the brake discs with cooling are placed sequentially onto the V-shaped support rods through their central holes. Then, the drive motor in the moving mechanism is activated, moving the support plate into the cooling chamber. Simultaneously, the fan, rotary motor, and thermoelectric cooler are activated. With the cooperation of the fan, thermoelectric cooler, and air distribution plate, cool air is evenly blown from the outlet to cool the brake discs entering the cooling chamber. The rotary motor drives the support shaft to rotate, causing the brake discs placed on the V-shaped support rods to rotate accordingly, ensuring full contact with the cool airflow. Driven by the actuator, the brake disc placed on the V-shaped support rod undergoes preliminary air cooling between the cooling boxes, then moves to the top of the cooling pool. The lifting device is then activated, causing the lifting support plate to descend, allowing the brake disc placed on the V-shaped support rod to enter the cooling pool containing coolant for further cooling. The preliminary air cooling reduces the temperature before entering the coolant, preventing the brake disc from cooling down too quickly. As the brake disc enters the coolant in the cooling pool, the rotary motor continues to drive the support shaft to rotate, ensuring that the brake disc is in full contact with the coolant and guaranteeing the stability of the brake disc cooling effect.
