The invention relates to a device and method for measuring the internal resistance of a bench based on a reaction-force drum brake inspection bench. The device is mainly composed of a force application and force measurement device (A), a fixing device (B), a reaction-force drum brake inspection table (C), and a tire suspension device (D). The measuring device and method can be applied to bench calibration. By adjusting the force applying and force measuring device (A), a load is applied to the tire suspension device (D), so as to simulate the wheel load in the actual vehicle inspection process, and obtain different The internal resistance value of the gantry under the wheel load is used to establish the relationship between the internal resistance of the gantry and the axle load. For different models, determine the corresponding bench internal resistance F according to different axle loads x , to compensate the error of the braking force and improve the detection accuracy. The device can be widely used in automobile inspection, testing and scientific research institutions.
Description
technical field [0001] The invention relates to a vehicle detection device and method, in particular to a bench internal resistance measurement device and method based on a reaction-force drum brake inspection bench. Background technique [0002] The braking performance of a vehicle is directly related to the driving safety of the vehicle, and it is one of the items that must be checked for the safety performance of the vehicle. The brake test bench is often used to test the braking performance. At present, the braking test equipment used in the domestic vehicle performance testing station is mostly reaction force Type roller brake test bench. The test principle is: the wheel to be tested is placed between the main and driven rollers, and the third roller is pressed down to make the proximity switch turn on. The motor is started through the delay circuit, and the wheel is driven to rotate at a low speed through the reducer, the chain drive and the main and driven rollers. A...
