Flexible suspension and force sensing device for loader

Abstract

The invention discloses a flexible suspension and force sensing device for a loader, belonging to the technical field of steering engine testing systems, precise machinery and the like. The device is characterized by comprising a front supporting device, a back supporting device, a force measuring flexible connecting rod and a force measuring sensitive element, wherein a front suspension device consists of two flexible connecting rods in the Y-axis direction and the Z-axis direction; one end of each flexible connecting rod is fixedly connected to a force loader, and the other end of each flexible connecting rod is fixedly connected to a supporting seat; the back supporting device consists of two flexible connecting rods in the Y-axis direction and the Z-axis direction; one section of each flexible connecting rod is fixedly connected to the force loader, and the other section of each flexible connecting rod is fixedly connected to the supporting seat; one section of the force measuring flexible connecting rod is fixedly connected to the loader, and the other section of the force measuring flexible connecting rod is fixedly connected to the force measuring sensitive element; a force measuring element is fixedly connected to the supporting seat; the external loading force of the loader is equal to force applied to the loader and is applied to the force measuring sensitive element through the force measuring flexible connecting rod; and the magnitude of the loading force of the loader can be measured by measuring the strain of the force measuring sensitive element.

Description

technical field [0001] The loader flexible suspension and force sensing device belong to the technical fields of a steering gear test system, precision machinery and the like. Background technique [0002] The steering gear test system usually consists of a load loader, a steering gear bracket, a load cell, and a test computer. Usually, one end of the steering gear to be tested is attached to the steering gear bracket, and the other end is connected to the loader through a load cell. The disadvantage of the above method is that the force sensor follows the movement of the steering gear output component, and the power supply and signal output cable of the force sensor also follow the movement, which is inconvenient to use. . SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a loader flexible suspension and force sensing device, which can save the force measuring sensor between the load loader and the steering gear in the steering gear tes...

Problems solved by technology

The disadvantage of the above method is that the force sensor moves with the output parts of the steering gear, and the power supply and signal output cables of the force sensor also follow the movement, which is inconvenient to use. Due to the quality of the force sensor itself, it will bring additional inertial force when acceleration occurs.
