Embodiment

[0031] This implementation provides a combined weighing platform pavement structure, such as figure 2 As shown, it is mainly used to measure the load of the braking force on each axle group during the braking process of a multi-axle group motor vehicle. It includes: two sets of subgrades 6 arranged at both ends along the length direction of the weighing platform, and accommodating grooves are arranged between the two sets of subgrades 6; at least two stressed beams 4 arranged side by side along the length direction are arranged on the said platform Inside the accommodating groove, the stressed beam can be deformed under load; several sensors are installed on the side walls of each stressed beam 4, and when the stressed beam 4 is deformed, the The sensor deforms synchronously with the stressed beam 4, so that the sensor outputs a signal corresponding to the deformation of the stressed beam 4; the sensor includes: two stress-sensing teeth 1 connected vertically to each other, t...

Abstract

The invention provides a combined type weighing platform paving structure which is mainly used for measuring numeric values of braking force and self loading of a multiple axle group motor vehicle during braking processes. 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 overlappedmanner, 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 two mutually perpendicular vertical force strain gages arranged between the two horizontal force strain gages. Via arrangement of the horizontal force strain gagesand the vertical force strain gages, numeric values of braking force that each axle group in the motor vehicle receives and real time weight of the motor vehicle can be measured during braking processes, and a change relation between the two can be detected.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a combined 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 motor vehicle, once...
