Factors Causing Temperature Rise in Automotive Testing Equipment

Cars are a part of people's work and life in modern society. With the continuous improvement of people's requirements for driving and comfort, automotive inspection equipment technology is receiving more and more attention, and automotive inspection and maintenance have shown huge market prospects. As an important part of automotive diagnostic equipment, automotive testing equipment is suitable for many places such as quality inspection departments of automobile manufacturers, government inspection stations, 4S stores, automobile repair shops, and automotive technology training schools.

Automotive technology status: The sum of quantitatively measured parameter values that characterize the appearance and performance of a car at a certain moment. The diagnostic parameters of automobiles include working process parameters, accompanying process parameters, and geometric dimension parameters. Classification of measurement errors: According to the relative representation method of measurement errors, they are divided into systematic, random, and negligent according to the occurrence pattern of measurement errors, and static and dynamic according to the state of measurement errors. The selection principles of diagnostic parameters include sensitivity, single value, stability, information, and economy. The types of diagnostic criteria are: industry, local, and enterprise.

Automotive testing equipment: an inspection and measurement conducted to determine the technical condition or working ability of a vehicle. Automotive diagnosis: Testing, analysis, and judgment conducted to determine the technical condition of a vehicle or to identify the location and cause of a malfunction without disassembling (or only removing individual small components). Self diagnosis method: It is a method of using the self diagnosis function of the automotive electronic control unit to characterize the location of the fault through the output of fault codes. Artificial experience diagnosis method: It does not require instruments and equipment, but has a strong dependence on the experience of diagnostic personnel, slow diagnostic speed, poor accuracy, and cannot be quantitatively analyzed. Modern instrument and equipment diagnostic method: Its diagnosis, accuracy, and quantitative analysis are high, but this method requires a large amount of factory space and investment.

The car inspection line mainly consists of three parts: brake inspection station, suspension inspection station, and side slip inspection station. The brake detection platform is a device that detects the braking performance of a car, which directly affects the driving performance of the car. The most common brake detection stations in the market are drum type brake detection stations, in addition to flat plate brake detection stations. This device mainly detects four parameters: wheel braking force, braking force balance, ellipticity, and braking force.

The temperature rise of automotive testing equipment is generally caused by problems with the quality of the bearings themselves, which generate excessive heat during high-speed rotation. What specific factors are causing this?

1. The bearing shell is damaged and should be recast.

2. The clearance between the bearing and the neck of the car inspection equipment is too small, and the clearance should be scraped and adjusted.

3. The oil inlet temperature is too high. The cooling water volume of the oil cooler of the automotive testing equipment should be adjusted.

4. The oil is mixed with water, dirt, or spoilage, which affects the lubrication effect.

5. Dirt enters the bearings and wears out the bearing shells. The bearings and lubricating oil pipelines of the car inspection equipment should be cleaned, and the bushings should be scraped and ground.

6. The bearing lubricating oil throttle ring has a small aperture and insufficient oil intake. Therefore, the throttle ring aperture should be appropriately enlarged.
