Problems solved by technology

In the prior art, most of the sensors use an integral circular main body, a connecting beam is set between the inner ring and the outer ring, and strain gauges are pasted on the connecting beam to measure the six-component force of the tire, but this It is difficult for this kind of sensor to meet the range requirements when measuring the six-component force of tires with a large range. At the same time, a single large-range sensor also has the problem of high cost and difficulty in processing and manufacturing, which makes it difficult to measure the six-component force of tires with a large range.

Abstract

The invention provides an integrated six-component sensor. The sensor comprises an integrally formed main body and a strain gauge arranged on the main body, the main body comprises a fixed end, a connecting end and a bridge body assembly arranged between the fixed end and the connecting end, and the bridge body assembly comprises a first connecting bridge, a second connecting bridge, a third connecting bridge and a fourth connecting bridge; and each connecting bridge comprises two patch surfaces, each patch surface is provided with at least four strain gauges which are symmetrically pasted along the center line of the patch surface in the length direction and correspond to each other in position, and the strain gauges are electrically connected to form a plurality of full-bridge circuits for measuring six-component force. According to the invention, six-component measurement of a wide-range tire can be carried out, and crosstalk is effectively eliminated.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of six-component force sensors, in particular to an integrated six-component force sensor. Background technique [0002] The wheel is the only key functional assembly component of the vehicle that is in direct contact with the ground. All the basic performance of the vehicle is closely related to the wheel. Therefore, the measurement of the wheel force is of great significance for analyzing the dynamic performance of the vehicle. [0003] In the wheel coordinate system, the wheel is subjected to loads in six directions including three forces of Fx, Fy, and Fz and three moments of Mx, My, and Mz. The six-component force sensor is widely used to collect the three-directional force and three-directional torque transmitted from the tire to the body of the car. In the prior art, most of the sensors use an integral circular main body, a connecting beam is set between the inner ring and the o...
