Automotive rut depth measuring instrument

Abstract

The invention discloses an automotive rut depth measuring instrument, consisting of a valve seat assembly (I), a hinge assembly (II), a dragging wheel assembly (III), a long upright column and a long L-shaped swing rod. The valve seat assembly (I) is arranged on the right end of the long upright column; the left end of the long upright column is fixedly connected with the right end of the hinge assembly (II); the left end of the hinge assembly (II) is fixedly connected with the upper end of the long L-shaped swing rod; the lower end of the long L-shaped swing rod is fixedly connected with the left end of the dragging wheel assembly (III). The long upright column consists of two, three, four or five sections of upright columns according to length of a vehicle; and the two, three, four or five sections of the upright columns forming the long upright column are sequentially connected by threads from end to end. The long L-shaped swing rod consists of one, two, three or four sections of straight swing rods and an L-shaped swing rod (15) according to the length of the vehicle, and the one, two, three or four sections of the straight swing rods and the L-shaped swing rod (15) for forming the long L-shaped swing rod are sequentially connected by the threads from end to end. The automotive rut depth measuring instrument solves a problem that some rut depth measuring instruments with large number of parts result in decreasing of accuracy.

Description

technical field [0001] The invention relates to a measuring mechanism for automobile ruts, more precisely, the invention relates to an automobile rut depth measuring instrument for producing continuous ruts when automobiles run on soft ground. Background technique [0002] At present, most of the measuring devices for the ruts produced by cars running on soft roads are laser ranging devices, that is, laser sensors are used to measure the continuous rut ​​depths produced by cars, and the cost of laser sensors for measuring rut depths is relatively high. In addition, its structure and performance make it unsuitable for operation in deserts or uninhabited areas. [0003] The angular displacement is measured by a precision conductive plastic potentiometer, which is widely used in the industrial sector at present. In actual use, the sensor should have a long service life, high measurement accuracy, can work in an environment with a lot of dust and vibration, and the cost is low....
