Controllable Torque Accident Vehicle Braking Force Detection Device

Abstract

The invention relates to a torque controllable accident vehicle braking force detecting device. An asynchronous motor and an electromagnetic slip frequency clutch are matched to form a slip motor, torque dynamic loading is conducted by using the slip motor, so that the braking torque of an accident vehicle brake is obtained, and accident vehicle braking performance is evaluated. The device comprises a detecting device (A), a supporting device (B) and a guiding device (C). The detecting device (A) delivers the torque generated by the slip motor to a force exerting chuck, a proportional integration differentiation (PID) controller is used for controlling outputting of variable torque, and a brake braking force curve is obtained. The supporting device (B) is connected with the detecting device through an upper supporting plate in a rigid mode and is matched with the guiding device through an upper guide track smoothly. The guiding device (C) controls the detecting device and the supporting device to move vertically through a linear guide track. By means of the torque controllable accident vehicle braking force detecting device, the problem that braking force of accident vehicles which do not meet road testing or platform testing detecting conditions can not be detected is solved, and meanwhile the anti lock braking system (ABS) performance of automobiles is evaluated.

Description

technical field [0001] The invention belongs to automobile performance detection equipment, in particular to a controllable torque accident vehicle braking force detection device. The controllable torque accident vehicle braking force detection device can not only detect the accident vehicle braking force, but also evaluate the performance of the vehicle ABS system. The device has high detection precision, good system reliability, simple structure and reasonable design, so that the motor vehicle appraisal service is more scientific and objective, and the appraisal result is more credible. Background technique [0002] Due to the growth of automobile ownership and traffic accidents in our country, quality disputes and accident disputes related to automobiles have also increased. The braking performance of a car is directly related to the safety of the car. When appraising the accident caused by the car, the appraiser made some standard requirements for the brake performance...

AI Technical Summary

Problems solved by technology

In most cases, the inspected vehicle has been damaged due to the collision, lost the driving ability, does not have the technical conditions for road test or bench test inspection, and cannot be tested for road test or bench test

Therefore, most traffic accident judicial appraisal agencies can only use the method of appearance observation to make rough qualitative judgments for the accident vehicles that lose their driving ability, and cannot detect specific technical parameters. Their appraisal conclusions lack scientificity and objectivity
