Description

Technical Field

[0001] The utility model relates to the technical field of truck brake shoe temperature data sensors, in particular to a truck brake shoe temperature data sensor. Background Art

[0002] The brake shoe is a critical safety component in a vehicle's braking system. It is a crescent-shaped accessory mounted on the brake drum. Its primary function is to be pushed outward by the action of the brake cam or push rod, pressing against the brake drum to achieve braking. The brake shoe is the friction element of a drum brake and, in addition to sufficient strength and rigidity, should also possess a high and stable coefficient of friction, appropriate wear resistance, heat resistance, heat dissipation, and heat capacity. Heavy trucks traveling downhill require extended braking time, which can cause the brake shoe to heat up. Since the temperature of the brake shoe cannot be measured during braking, excessively high temperatures can cause tire damage or brake failure, posing a safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Example 1

[0023] Reference Figures 1-4 This embodiment proposes a truck brake shoe temperature data sensor. By setting a temperature measuring device, it solves the problem that the temperature on the brake shoe cannot be measured during braking, resulting in excessive temperature and causing tire damage or brake failure. The device includes a mounting plate 1, on which two sets of brake shoes 2 are mounted. Two symmetrical sets of connecting blocks 3 are fixedly mounted on the mounting plate 1. The connecting blocks 3 are provided with openings 31. Two symmetrical sets of No. 1 contacts 7 are fixedly mounted in the connecting blocks 3. Two sets of No. 2 contacts 71 used in conjunction with the No. 1 contacts 7 are fixedly mounted on the temperature measuring device housing 45. Through the No. 1 contacts 7 and the No. 2 contacts, the No. 1 contacts 7 and the No. 2 contacts are connected. The contact at 71 causes the temperature sensor in the temperature measuring device housing 45 to start working and measure the temperature of the brake shoe 2. Two sets of bidirectional hydraulic rods 8 fixedly connected to the brake shoe 2 are fixedly mounted on the mounting plate 1. The two sets of bidirectional hydraulic rods 8 drive the brake shoe 2 to move during braking. Two symmetrical sets of brake pads 9 are fixedly mounted on the brake shoe 2. A temperature measuring device 4 for measuring the temperature of the brake shoe 2 during braking is mounted on the connecting block 3. An adjusting device 6 for continuously detecting the temperature of the brake shoe 2 is mounted in the connecting block 3. The temperature measuring device 4 can measure the temperature of the brake shoe 2 during braking to prevent the brake shoe 2 from overheating.

[0024] The temperature measuring device 4 includes a sliding groove 41 provided in the connecting block 3, a support plate 42 is slidably installed in the sliding groove 41, a mounting groove 43 is provided on the support plate 42, two symmetrical connecting rods 44 are fixedly installed on the support plate 42, the connecting rods 44 pass through the connecting block 3 and are fixedly connected to the brake shoe 2, a temperature measuring device housing 45 is slidably installed in the mounting groove 43, an infrared temperature sensor for measuring the stability of the brake shoe 2 is installed in the temperature measuring device housing 45, and a temperature measuring device housing 45 is fixedly installed on the mounting groove 43. The two groups of No. 1 limit rods 46 are sleeved on the No. 1 limit rod 46, so that the temperature measuring device housing 45 can be quickly reset. Four groups of No. 1 magnetic blocks 48 are installed on the mounting groove 43 and the temperature measuring device housing 45 to attract each other. The connection of the No. 1 magnetic block 48 avoids the situation where the temperature measuring device housing 45 cannot be reset. Two symmetrical groups of limit grooves 5 are opened in the connecting block 3, and two symmetrical groups of No. 2 limit rods 51 are fixedly installed in the limit grooves 5. The No. 2 limit rods 51 are sleeved on the No. 2 springs 52, so that the bevel block 5 3 can be quickly reset. A bevel block 53 is slidably installed on the second limit rod 51, and the opening 31 is closed by the bevel block 53 to prevent dust accumulation on the temperature measuring device from causing inaccurate temperature measurement. Two symmetrical sets of rollers 54 are fixedly installed on the temperature measuring device housing 45 to facilitate the movement of the temperature measuring device housing 45. When braking, the bidirectional hydraulic rod 8 is activated to drive the brake shoe 2 to move. The movement of the brake shoe 2 drives the support plate 42 connected to the connecting rod 44 to move in the sliding groove 41. The movement of the support plate 42 drives the temperature measuring device housing 45 on the support plate 42 to move. Under the action of the roller 54, the bevel block 53 is easily pushed into the limit groove 5, so that the opening 31 is opened and the temperature measuring device housing 45 moves to the outside of the connecting block 3. The first contact 7 contacts the second contact 71, causing the temperature measuring device to start working. When braking, the temperature on the brake shoe 2 is measured, so that the driver can appropriately change the braking method according to its temperature, avoiding the situation where the temperature on the brake shoe 2 cannot be measured during braking, resulting in excessive temperature causing tire damage or brake failure.

[0025] Example 2

[0026] Based on Example 1, the technical solution proposed in Example 1 is used to solve the disadvantage that the temperature on the brake shoe cannot be measured during braking, resulting in excessive temperature causing tire damage or brake failure. By real-time monitoring of the temperature on the brake shoe, the driver's braking condition can be appropriately changed.

[0027] Reference Figures 1-4The adjusting device 6 includes an electric telescopic rod 61 fixedly installed in the sliding groove 41 and located directly below the temperature measuring device housing 45. Two sets of attractive second magnetic blocks 62 are installed on the movable end of the electric telescopic rod 61 and the temperature measuring device housing 45. The connection between the second magnetic blocks 62 enables the temperature measuring device housing 45 to be quickly reset. Since the movable end of the electric telescopic rod 61 is not in contact with the temperature measuring device housing 45, when it is necessary to continuously measure the temperature change of the brake shoe 2, the hydraulic rod is started to make the second magnetic block 62 at the movable end of the hydraulic rod move upward, and pass through the support plate 42 to be attracted by the second magnetic block 62 at the bottom of the temperature measuring device housing 45. The hydraulic rod drives the temperature measuring device housing 45 to continue to move upward and move out of the connecting block 3, so that the temperature on the brake shoe 2 can be monitored in real time, making its monitoring effect better.
