Embodiment 1

[0031] This embodiment provides a weighing platform, including: a stressed beam 4, capable of deformation under load; several sensors, installed on the side wall of the stressed beam 4, the sensors can be deformed under the action of external force Deformation; when the stressed beam 4 is deformed, the sensor and the stressed beam 4 deform synchronously, so that the sensor outputs a signal corresponding to the deformation of the stressed beam 4;

[0032] The sensor includes: two stress-sensing teeth 1 vertically connected to each other. The overlapping parts of the two stress-sensing teeth 1 are provided with strain gauges that elongate or contract synchronously with the stress-sensing teeth 1. The strain gauges It includes: two horizontal force strain gauges 2, extending along the horizontal direction; two vertical force strain gauges 3 perpendicular to each other, arranged between the two horizontal force strain gauges 2.

[0033] The sensor provided by the present invention...

Embodiment 2

[0043] This embodiment provides a weighing platform pavement structure, such as figure 2 As shown, it includes: at least one set of weighing platform described in Embodiment 1; two groups of roadbeds 6 are arranged at both ends along the length direction of the said weighing platform, and accommodating grooves are arranged between the two groups of roadbeds 6. The force beam 4 is arranged inside the receiving groove, and the top of the force beam 4 is flush with the top of the roadbed 6 .

[0044] Several groups of fixed support foundations 7 arranged at intervals are arranged between the bottom surface of the accommodation tank and the stressed beam 4, and the fixed support foundations 7 are used to adjust the height position of the stressed beam 4 so that the stressed beam 4 The top surface of the force beam is always flush with the top of the embankment.

Abstract

The invention provides a weighing platform and a weighing platform paving structure, a sensor is arranged in the weighing platform, and the sensor comprises two stress induction teeth that are mutually perpendicularly connected; parts, arranged in an overlapped manner, of the stress induction teeth are provided with strain gages that stretch or contract along with the stress induction teeth; the strain gages include two horizontal force strain gages that extend along a horizontal direction and a vertical force strain gage arranged between the two horizontal force strain gages. Via arrangementof the horizontal force strain gages and the vertical force strain gage, numeric values of braking force that a motor vehicle receives and real time weight of the motor vehicle can be measured, and achange relation between the two can be detected.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a weighing platform and a weighing platform pavement structure 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 moto...
