Problems solved by technology
[0004] (1) The displacement sensor is arranged on the parts of the chassis under the vehicle, and the space is so narrow that it cannot even be arranged;
[0005] (2) The pasting arrangement is unreliable, and the underside of the car is easily hit by stones and easily falls off;
[0006] (3) The versatility is extremely poor, and the layout scheme of each model is different;
[0007] (4) The device is under the vehicle, which is not easy to install, inspect and maintain

Embodiment Construction
[0034] The present invention will be further described below in conjunction with accompanying drawing.
[0035] like figure 1 As shown, a device for measuring the Z-direction displacement of a wheel during dynamic driving of a vehicle includes an L-shaped bracket 1 for mounting on a vehicle body 9, a slip ring bracket 8 for mounting on a wheel 10, a radial bearing 6, Stator shaft 7, nut 4 and stay wire displacement sensor 3.
[0036] like figure 2 As shown, the L-shaped support 1 includes a vertical plate 1a and a horizontal plate 1e, and the vertical plate 1a and the horizontal plate 1e of the L-shaped support 1 are provided with lightening holes 1c, which reduces the weight of the L-shaped support 1. Weight, that is, the motion inertia of the L-shaped bracket 1 is reduced, so as to better adapt to the bumps of the vehicle. The horizontal plate 1e is provided with a plurality of first installation holes 1d. In this embodiment, there are eight first installation holes 1d, ...

The invention discloses a device for measuring Z-direction displacement of a vehicle wheel during dynamic running of a vehicle, which comprises an L-shaped bracket, a slip ring bracket, a radial bearing, a stator shaft, nuts and a stay wire displacement sensor; wherein the L-shaped bracket comprises a vertical plate and a horizontal plate, and a plurality of first mounting holes are formed in thehorizontal plate; the slip ring bracket comprises a central circular ring and a plurality of connecting arms, and second mounting holes are formed in the connecting arms; the radial bearing is arranged on the central circular ring in a matching way through a shaft hole; the stator shaft is arranged on the radial bearing in a matching way through the shaft hole, one ends of the nuts are connected with the connecting arms through the second mounting holes by use of first screws, the other ends of the nuts are connected with the vehicle wheel, and the axis of the nut is parallel to the axis of the stator shaft; and the stay wire displacement sensor is arranged on the bottom surface of the horizontal plate through the first mounting hole by use of a second screw, and the wire head end of the stay wire displacement sensor is arranged on the stator shaft. The device is used for measuring the Z-direction displacement signal of the vehicle wheel, and has the advantages of convenient arrangement, reliable measurement, strong universality and easy inspection.
Description
technical field [0001] The invention belongs to the technical field of automobile testing devices, and in particular relates to a device for measuring the Z-direction displacement of a wheel during dynamic running of a vehicle. Background technique [0002] Road spectrum collection is an extremely important work in the process of automobile research and development, and it is an important means to study the reliability of the whole vehicle, and provides a scientific basis for the design, analysis and test of the fatigue life of the whole vehicle and parts. [0003] At present, major domestic automobile companies have successively carried out road spectrum collection work. The Z-direction displacement signal of the dynamic driving wheel relative to the body of the vehicle is one of the important signals in the road spectrum collection. In the actual measurement and collection of wheel Z-direction displacement signals, major OEMs currently mainly use pull-wire displacement sen...
