Hub sensor mounting method and fixing device thereof

Abstract

The invention discloses a hub sensor mounting method and a fixing device thereof. The fixing device comprises a fixed plate and an alignment device, wherein the alignment device is fixed on a compression nut of the fixed plate, and comprises a stainless steel pipe and a shell; and the stainless steel pipe is fixedly connected with the shell through a fixing nut. By the method and the device, the condition that a sensor is not damaged can be ensured, and the conditions of inaccurate measured temperatures caused by mounting errors can be reduced; and wheels are not required to be dismounted or holes are not required to be prepunched when the position of the sensor is adjusted for a second time, and only the position of the fixed plate is required to be adjusted simply and conveniently. The mounting method is suitable for sensors for monitoring the temperatures of hubs, is suitable for mounting sensors for monitoring the working conditions of all parts inside the hubs or brakes and is suitable for fixedly mounting the sensors under other severer environments.

Description

technical field [0001] The invention relates to a method for installing a hub sensor and a fixing device thereof. Background technique [0002] China's heavy-duty trucks generally use drum brakes, which have poor heat dissipation performance. At present, there is no unified standard for judging the excessive temperature of brake drums in my country, and there is no standard for brake temperature of various axle manufacturers. Relevant restrictions, so at present in the automobile maintenance industry, there are various judgments on the excessive temperature of the brake drum. Even some maintenance companies rely on hand models and sniffing for detection, which is extremely unscientific and very random. If it is installed in the brake drum The sensor can truly reflect the temperature of the hub itself, that is, science is not arbitrary. [0003] The internal space of the brake is extremely limited. Since the heat is generated by the friction between the brake pad and the brake...

[0002] China's heavy-duty trucks generally use drum brakes, which have poor heat dissipation performance. At present, there is no unified standard for judging the excessive temperature of brake drums in my country, and there is no standard for brake temperature of various axle manufacturers. Relevant restrictions, so at present in the automobile maintenance industry, there are various judgments on the excessive temperature of the brake drum. Even some maintenance companies rely on hand models and sniffing for detection, which is extremely unscientific and very random. If it is installed in the brake drum The sensor can truly reflect the temperature of the hub itself, which is scientific and has no randomness

[0003] The internal space of the brake is extremely limited. Since the heat is generated by the friction between the brake pad and the brake drum, the material of the brake pad itself has extremely poor thermal conductivity, and the heat transferred to the brake shoe is very limited, so most of the heat is concentrated in the brake drum. On the other hand, fixing the sensor on the brake drum can reflect its own temperature the most, and the brake drum itself is rotating, so it is impossible to fix the sensor on it

[0004] If the sensor is fixed outside the hub, it is easily affected by the external environment, and it is easy to damage the sensor. If it is fixed inside, if it is not installed properly, it will be worn by the hub or brake shoes, thereby damaging the sensor.

Therefore, the correct installation method is very important to obtain the real temperature of the hub. The common installation method is to directly punch a hole on the dust shield, and then weld a nut to fix the sensor on the nut. Although this method is simple, the position It is not adjustable. Once the hub is installed, it is found to be worn by the hub. When adjusting the position, it is necessary to remove the wheel again, punch holes, and weld.
