Embodiment 1

[0039] This embodiment provides a method for measuring braking force using a three-dimensional combined force measuring device, including the following steps: S1. The motor vehicle starts and drives to the three-dimensional combined force measuring device 1 at a set speed, and the three-dimensional combined force measuring device 1 is a cube; S2. When the motor vehicle travels to the three-dimensional combined force measuring device, the brakes are applied, and the machine is obtained by a number of horizontal sensors installed below the platen 1 and parallel to the horizontal side length of the platen 1. The braking force and the sideslip force of the motor car are output together; the three-dimensional combined force measuring device includes a horizontal connection bracket 8 with a through hole, and the two ends of each horizontal sensor are respectively provided with a horizontal connection bracket 8, and the horizontal sensor The horizontal connection bracket 8 is fixedly ...

Abstract

The invention provides a method of measuring the braking force using a three-dimensional combined force measuring device. A three-dimensional combined force measuring device provided in steps S1 and S2 has horizontal connecting brackets with mounting through holes. Each horizontal sensor is provided with the horizontal connecting brackets at both ends thereof. The horizontal sensors and the mounting through holes are can only be mated and connected rotatably about axes of the mounting through holes. The horizontal connecting bracket is fixedly connected with a platen. When the platen is subjected to a force in a vertical (z-axis) direction, a downward movement occurs at the force point of the platen. Since the horizontal sensor in the x-axis and y-axis directions and the mounting through holes can only be mated and connected rotatably about the axes of the mounting through holes so that the horizontal sensors remain stable without being stretched or squeezed, the horizontal sensors in the x-axis and y-axis directions will not send out a signal, thus avoiding the occurrence of inter-dimensional coupling. The braking force and sideslip force of a motor vehicle side can be accurately obtained.

Description

technical field [0001] The invention relates to the technical field of motor vehicle braking force measurement, in particular to a method for measuring braking force using a three-dimensional combined force measuring device. Background technique [0002] When a motor vehicle is running, it is often necessary to brake it. The force given by the vehicle brake to the motor vehicle is divided into braking force and sideslip force. The size of the braking force determines the length of the braking time of the motor vehicle. If the braking force is too small, the braking time of the motor vehicle will be too long. At this time, there may be a danger of colliding with other motor vehicles, which seriously affects the normal passage of road vehicles. Simultaneously, because the two or four driving wheels of motor vehicle are locked due to mechanical error, there may be inconsistencies in the braking between the wheels. During the driving process of the motor vehicle, once the later...
