Embodiment

[0029] This embodiment provides a sensor, such as figure 2 As shown, it includes: two stress-sensing teeth 1 vertically connected to each other, and the overlapping parts of the two stress-sensing teeth are provided with strain gauges that elongate or contract synchronously with the stress-sensing teeth, and the strain gauges include: There are two horizontal force strain gauges 2 extending along the horizontal direction; two vertical force strain gauges 3 perpendicular to each other are arranged between the two horizontal force strain gauges.

[0030] The sensor provided in this embodiment is mainly used on the horizontal force beam. The horizontal force beam is set on the ground. The vehicle's own load.

[0031] In this embodiment, the side of the stress-sensing tooth away from the strain gauge is provided with a stress-sensing slot.

[0032] In this embodiment, the angle between any one of the two vertical force strain gauges and the horizontal line is 45° or 135°. From...

Abstract

The invention provides a sensor including two stress induction teeth in mutual perpendicular connection. An overlapped part of the two stress induction teeth is provided with a strain gage elongatingor contracting along with the stress induction teeth synchronously. The strain gage includes two horizontal force stress gage extending along the horizontal direction and two vertical force stress gage perpendicular to each other and arranged between the two horizontal force stress gage. Through the horizontal force stress gage and the vertical force stress gage, the magnitudes of the horizontal force (braking force) and the shearing force (load) acting on the sensor can be measured.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a sensor for measuring the force (horizontal force) during the braking process of a motor vehicle. 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 lateral sliding force of the motor...
