Problems solved by technology

[0004] At present, depending on the hinge structure, sometimes it is impossible to measure the load borne by part B when it is working. Sometimes the load borne by part B can be measured by pasting strain gauges on part B, but the accuracy of the measurement results is often low, and the load measurement method is not universally applicable

Embodiment Construction

[0040] The connection points between vehicle chassis parts and the connection points between chassis parts and powertrain parts are widely used in hinged structures. Due to the compact structure of the chassis, the hinge point on the vehicle is usually reflected in two parts connected to each other. Suppose the two parts are part A and part B respectively, wherein: part A is the fixed end, and the hinge point of part A is located at Two metal plates arranged in parallel with a certain distance and processed with through holes. The hinge point of part B adopts a bushing structure, that is, there is a metal inner tube at the hinge point, and rubber and other materials are used to fill the space between the metal inner tube and the body of part B.

[0041] Part A and part B are clamped and connected by bolts to form a hinged structure. When working, part A and part B mainly transmit force through contact friction between each other, while the bolt basically does not bear shear f...

Abstract

The invention relates to a load measurement system of a rotation part in a hinge structure. The hinge structure comprises a simulation fixing part and the rotation part, wherein the simulation fixingpart and the rotation part are coupled in a hinge mode to form a first hinge point and a second hinge point. The load measurement system comprises a cylindrical member, a first limit member, a secondlimit member, a first measurement unit and a second measurement unit, wherein the first measurement unit is suitable for measuring bearing force of the rotation part in the first direction axis and bearing force of the rotation part in the second direction axis, the first direction axis is perpendicular to the second direction axis, the first direction axis and the second direction axis are respectively perpendicular to the axial direction of the cylindrical member, and the second measurement unit is suitable for measuring bearing force of the rotation part in the first direction axis and bearing force of the rotation part in the second direction axis. The hinge structure is advantaged in that universal applicability of load measurement of the hinge structure can be realized, and accuracyof the measurement result is improved.

Description

technical field [0001] The invention relates to the field of load measurement, in particular to a load measurement system for rotating parts in a hinged structure. Background technique [0002] The connection points between vehicle chassis parts and the connection points between chassis parts and powertrain parts are widely used in hinged structures.
