Problems solved by technology

[0002] At present, the detection of the braking performance of damaged vehicles is usually only a qualitative judgment of whether it is effective. There is no detection data, and the detection results have certain risks. Detect walking vehicles, but cannot detect vehicles that cannot walk due to traffic accident damage. In addition, the roller brake performance test bench and the plate brake performance test bench are large in size and weight, and need to be installed in a fixed place, which is inconvenient to move

Embodiment 1

[0016] Such as figure 1 As shown, the present invention provides a damaged vehicle braking performance detection device, including a loading rod 1, a braking force loader 2, a braking force sensor 3, a brake pedal force sensor 6 installed on the pedal, a data acquisition card 7 and computer 8, one end of the loading rod 1 is provided with a flange 4 for connecting the wheel, and the other end is provided with an adjustment block 5 capable of adjusting the loading position, and the braking force loader 2 is located directly below the adjustment block 5, and the A brake force sensor 3 is arranged between the brake force loader 2 and the adjustment block 5, and the brake force sensor 3 and the brake pedal force sensor 6 are respectively connected with the data acquisition card 7, and the data acquisition card 7 is connected with the Computers 8 are connected.

[0017] The brake force sensor 3 is a flat wheel-spoke force sensor. According to the different types of vehicles to be ...

Embodiment 2

[0024] The difference from Embodiment 1 is that the pedal is equipped with an automatic pressurization mechanism, and the ways of pedal automatic pressurization are as follows:

[0025] 1. Screw mechanism adjustment A screw mechanism is installed on the surface of the brake pedal force sensor, and different pedal braking forces can be achieved by adjusting the screw.

[0026] 2. Servo motor-controlled hydraulic / pneumatic cylinder adjustment Install a servo motor-controlled hydraulic / pneumatic cylinder device at the pedal in the car, and adjust the height, front and rear, and left and right positions of the aluminum alloy frame feet according to the position of the seat installation point on the car, so that It can be connected and fixed with the seat mounting point. Retract the servo motor to the cylinder tail position, adjust the front and rear positions of the cylinder tail shaft, and make the lower part of the loading nylon head contact with the surface of the pedal force s...

Abstract

The invention, which relates to the technical field of vehicle braking performance detection, provides an apparatus for detecting a braking performance of a damaged vehicle. The apparatus comprises a loading rod, a braking force loader, a braking force sensor, a brake pedal force sensor installed at a pedal, a data acquisition card, and a computer. A flange connected with a wheel is arranged at one end of the loading rod and an adjusting block capable of adjusting a loading position is arranged at the other end. The braking force loader is arranged right below the adjusting block; and the braking force sensor is arranged between the braking force loader and the adjusting block. The braking force sensor and the brake pedal force sensor are respectively connected with the data acquisition card; and the data acquisition card is connected with the computer. With the apparatus, a braking performance of a vehicle that can not be driven due to damages caused by a traffic accident can be detected scientifically, accurately, and quantificationally. The provided apparatus has advantages of simple structure, small size, low cost, high portability, and good detection effect.

Description

technical field [0001] The invention relates to the technical field of vehicle braking performance detection, in particular to a damaged vehicle braking performance detection device. Background technique [0002] At present, the detection of the braking performance of damaged vehicles is usually only a qualitative judgment of whether it is effective. There is no detection data, and the detection results have certain risks. It is impossible to detect vehicles that cannot walk due to damage caused by traffic accidents. In addition, the roller brake performance test bench and plate brake performance test bench are bulky and heavy, and need to be installed in a fixed place, which is inconvenient to move. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a damaged vehicle braking performance detection device, which can scientifically, accurately and quantitatively detect the braking performance of a vehic...
