Problems solved by technology

[0002] At present, it is used to test the vehicle braking force device (abbreviated as brake table), because different manufacturers use different circuits, and the obtained data often vary greatly. The main reason is that the brake table is only statically calibrated and lacks the ability Equipment and detection device for dynamic braking force calibration

Embodiment

[0036] The vehicle dynamic braking force measuring device of the present invention is a device that directly obtains the tangential force of the wheel during the entire braking process of the vehicle. and the formation of braking friction. Since the spoke of the wheel is the component that transmits the driving force and braking force, the sensor is directly installed on the side of the spoke, which can most directly and quickly respond to the change of the output braking force. The process of implementing the braking force usually takes hundreds of milliseconds to several seconds. During this period, the continuous braking force collection is carried out, so that the shape of the braking establishment process, the difference between the left and right wheels, and the maximum value of the braking force can be directly and accurately measured. , these are the key data for judging the quality of the braking system.

[0037] Due to the above-mentioned characteristics, the brakin...

Abstract

The invention relates to a vehicle dynamic braking force measuring device. The device comprises a moving part which is arranged on a wheel and is used for dynamically acquiring braking force data in a vehicle braking process, and a vehicle-mounted part which is wirelessly connected with the moving part and is used for receiving and displaying the braking force data in real time, drawing a process curve, and further calculating braking data. Compared with the prior art, the vehicle dynamic braking force measuring device provided by the invention has the advantages of fast response, high precision and the like.

Description

technical field [0001] The present invention relates to a vehicle measuring device, in particular to a vehicle dynamic braking force measuring device. Background technique [0002] At present, it is used to detect the braking force device of the vehicle (referred to as the brake platform). Due to the different manufacturers and different circuits, the obtained data are often very different. The main reason is that the brake platform is only statically calibrated and lacks the ability to use Equipment and testing devices for dynamic braking force calibration. The braking process of the vehicle is a dynamic afterburning process. The static loading data of the brake platform cannot accurately express the dynamic loading data. Only the dynamically detected data can more accurately reflect the braking performance of the vehicle. Therefore, the dynamic braking force of the vehicle can not be accurately expressed. Measurement technology has become an urgent technical problem that ...
