A parking torque detection method of automobile rear brake

Abstract

The invention discloses a parking torque detection method of an automobile rear brake. The detection device is used for detection. The detection device includes a driving cylinder, a product fixing device for fixing the brake to be detected, and a pull wire. The detection device is provided with a tension sensor, a pressure sensor, Displacement sensor, the detection method is as follows: first, fix the brake to be tested on the product fixing device, start the drive cylinder to pull the cable, the tension on the cable is detected by the tension sensor, when the cable is tightened to the brake to be tested, the braking force of the brake to be tested Increase, the increase is detected by the pressure sensor installed on the product fixing device, and the displacement generated when the cable is pulled is detected by the displacement sensor. After one detection, the piston rod of the driving cylinder is retracted, and finally the test can be repeated or unloaded. Lower the brake to be inspected and replace other brakes to be inspected for detection. The invention has the advantages of convenient detection and more accurate and intuitive detected data.

Description

【Technical field】 [0001] The invention relates to a parking torque detection method of an automobile rear brake. 【Background technique】 [0002] The original detection of the parking torque efficiency of the brake caliper after the integrated parking of the car is controlled by the hand brake handle of the car. But this kind of detection equipment has the following defects: 1, each different product must use the matching handbrake handle to detect. This is very inconvenient in the manufacture and replacement of tooling, especially for double-cable products, which do not have an actual matching handbrake handle. 2. The cable used in the inspection is used at the same time as the matching handbrake handle. All the cables installed by the original factory are used. The cable installed by the original factory generally exceeds 1500mm in length, which is extremely cumbersome during use. 3. Due to the use of the handbrake handle mode, there is no digital quantitative monitoring ...

Problems solved by technology

However, this kind of testing equipment has the following defects: 1. Each different product must be tested with a matching handbrake handle

This is very inconvenient in the production and replacement of tooling, especially for double-cable products, there is no actual matching handbrake handle

2. The cable used in the inspection is used at the same time as the matching handbrake handle. All the cables installed by the original factory are used. The cable installed by the original factory generally exceeds 1500mm in length, which is extremely cumbersome during use.

3. Due to the use of the handbrake handle mode, there is no digital quantitative monitoring of the input force and input displacement on the actual arm, and quantitative analysis cannot be performed
