[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] The wheel six-component force meter is used to measure the force and torque on the wheel for vehicle dynamics analysis, structural strength analysis, braking and ABS research, etc. The wheel six-component force meter includes six-component force sensors, wheel hub or rim adapters, slip ring telemetry devices, wiring harnesses, data acquisition equipment and other components.

[0027] When the wheel six-component dynamometer collects the force and torque acting on the wheel, the wheel rotates continuously when the vehicle is driving, so the slip ring positioning rod in the wheel six-component dynamometer needs to be fixed at a fixed horizontal position. In addition, due to the change in the flatness of the road surface, the wheel moves vertically relative to the frame, so the slip ring positioning rod in the wheel six-component dynamometer needs to have the freedom of vertical movement.

[0028] In the related technologies, the wheel six-component dynamometer is mainly used in the field of passenger cars, and the focus is on the design of the wheel hub or rim adapter. When the wheel six-component dynamometer load test is performed on commercial vehicles, especially tractors, the turning condition will be affected by the semi-trailer, that is, the wheel six-component dynamometer slip ring positioning rod and its fixing device may interfere with the longitudinal beam of the semi-trailer.

[0029] In order to solve the above-mentioned problem, an embodiment of the present application provides a slip ring positioning rod fixing device for a six-component force meter of a center and rear axle wheel.

[0030] See also Figure 1 The fixing device includes a first tubular beam 1, a first connecting rod 2, a limiting rod 3, a second connecting rod 4 and a second tubular beam 5.

[0031] The first tube beam 1 , the first connecting rod 2 , the limiting rod 3 , the second connecting rod 4 and the second tube beam 5 are hinged in sequence, and a limiting hole 31 penetrating the limiting rod 3 is provided.

[0032] In the embodiment of the present application, the rotation direction of the first connecting rod 2 , the rotation direction of the second connecting rod 4 , and the axial direction of the limiting hole 31 are located in the same plane.

[0033] by Figure 1Taking the case where the axial direction of the middle limiting hole 31 is the vertical direction as an example, the first connecting rod 2 can rotate in the vertical plane around the connection between it and the limiting rod 3 , and the second connecting rod 4 can also rotate in the vertical plane around the connection between it and the limiting rod 3 .

[0034] In the embodiment of the present application, the first connecting rod 2 can be at a first preset angle relative to the radial direction of the limiting hole 31 , and the second connecting rod 4 can be at a second preset angle relative to the radial direction of the limiting hole 31 .

[0035] The following is a specific example to illustrate how to achieve that the first connecting rod 2 can be at a first preset angle relative to the radial direction of the limiting hole 31 , and the second connecting rod 4 can be at a second preset angle relative to the radial direction of the limiting hole 31 .

[0036] It should be noted that the first tubular beam 1 and the second tubular beam 5 have the same structure, and the first connecting rod 2 and the second connecting rod 4 have the same structure. The following only takes the connection method of the first tubular beam 1, the first connecting rod 2 and the limit rod 3 as an example for explanation, and the connection method of the second tubular beam 5, the second connecting rod 4 and the limit rod 3 will not be repeated.

[0037] In one achievable way, continue to see Figure 1 A first groove distributed along the vertical direction (the axial direction of the limiting hole 31) is opened at the end of the limiting rod 3, and a second groove distributed along the vertical direction is opened on the side wall of the first tube beam 1 near the end. Bosses are respectively provided at both ends of the first connecting rod 2, and through holes are opened on the bosses. A threaded hole passing through the first groove is opened at the end of the limiting rod 3, and a threaded hole distributed along its axial direction is opened at the end of the first tube beam 1. The bosses at both ends of the first connecting rod 2 are respectively inserted into the first groove and the second groove and fixed by bolts.

[0038] When it is necessary to adjust the angle between the first connecting rod 2 and the radial direction of the limiting hole 31, the bolts fixing the first tube beam 1 and the first connecting rod 2 or the bolts fixing the first connecting rod 2 and the limiting rod 3 can be loosened for adjustment. When it is adjusted to the preset angle, the bolts can be tightened to fix it.

[0039] In the embodiment of the present application, the first tube beam 1 and the second tube beam 5 are both used to connect the fender support tube beam of the wheel to be tested, and the limit hole 3 is used to be sleeved on the slip ring locating rod of the wheel six-component force meter to limit the position of the slip ring locating rod in the horizontal direction and enable the slip ring locating rod to have vertical movement freedom in the vertical direction.

[0040] See also Figure 2When the six-component force meter slip ring positioning rod fixing device for the middle and rear axle wheels provided in the embodiment of the present application is used, the first tube beam 1 is fixedly connected to the front fender support tube beam 6 of the wheel, and the second tube beam 5 is fixedly connected to the rear fender support tube beam 7 of the wheel. Of course, the above connection method is only exemplary and does not constitute a limitation on the embodiment of the present application. The first tube beam 1 can also be connected to the rear fender support tube beam 7 of the wheel, and the second tube beam 5 can also be connected to the front fender support tube beam 6 of the wheel.

[0041] After the first tube beam 1 is connected to the front fender support tube beam 6 of the wheel, and the second tube beam 5 is connected to the fender support tube beam 7 of the wheel, the wheel six-component force meter slip ring positioning rod is inserted into the limiting hole 31, and the radial direction angle of the first connecting rod 2 relative to the limiting hole 31 and the radial direction angle of the second connecting rod 4 relative to the limiting hole 31 are adjusted respectively, so that the limiting rod 3 is in a horizontal state, that is, the axial direction of the limiting hole 31 is in a vertical direction. At this time, the horizontal position of the slip ring positioning rod is limited according to the limiting hole 31 ( Figure 2 longitudinal and lateral directions), and to allow the slip ring positioning rod to have vertical freedom.

[0042] In the embodiment of the present application, the distance between the limiting rod and the axle axis can be adjusted by adjusting the radial angle of the first connecting rod 2 relative to the limiting hole 31 and the radial angle of the second connecting rod 4 relative to the limiting hole 31, thereby avoiding interference with the longitudinal beam of the semi-trailer.

[0043] In some embodiments, the limit hole 31 is suitable for being sleeved on the six-component force meter slip ring locating rod. Specifically, the diameter of the limit hole 31 can be equal to the diameter of the six-component force meter slip ring locating rod, or it can be slightly larger than the diameter of the six-component force meter slip ring locating rod. When the limit hole 31 is sleeved on the slip ring locating rod, if the diameter of the limit hole 31 is equal to the diameter of the six-component force meter slip ring locating rod, the limit hole 31 can limit the horizontal position of the slip ring locating rod and allow the slip ring locating rod to have vertical freedom; if the diameter of the limit hole 31 is slightly larger than the diameter of the slip ring locating rod (for example, the diameter of the limit hole 31 is 1 mm larger than the diameter of the slip ring locating rod), the slip ring locating rod has vertical freedom, and a slight offset will occur in the horizontal position, but it will not cause interference with the longitudinal beam of the semi-trailer.

[0044] It should be noted that those skilled in the art can set the diameter of the limiting hole 31 according to actual needs, and the embodiment of the present application does not limit this, as long as the limiting hole 31 is suitable for being sleeved on the slip ring positioning rod of the wheel six-component force meter, so that the horizontal position of the slip ring positioning rod remains unchanged or only changes slightly, and has vertical freedom. Of course, the position of the limiting hole 31 can also be set according to actual needs.

[0045] Optionally, the inner diameter of the limiting hole 31 is 14 mm.

[0046] In some embodiments, the first tube beam 1 is suitable for being mounted on the front fender support tube beam or the rear fender support tube beam of the wheel being tested; the second tube beam 5 is suitable for being mounted on the front fender support tube beam or the rear fender support tube beam of the wheel being tested.

[0047] Specifically, the inner diameter of the first tube beam 1 can be greater than or equal to the diameter of the front fender support tube beam or the rear fender support tube beam of the vehicle under test, and the inner diameter of the second tube beam 5 can be greater than or equal to the front fender support tube beam or the rear fender frame tube beam of the vehicle under test.

[0048] Furthermore, when the inner diameter of the first tube beam 1 is larger than the diameter of the front fender frame tube beam or the rear fender frame tube beam of the vehicle under test, at least one threaded hole penetrating the side wall thereof may be provided on the first tube beam 1, and when the first tube beam 1 is sleeved on the front fender frame tube beam or the rear fender frame tube beam of the vehicle under test, the two are fixed by bolts.

[0049] Similarly, at least one threaded hole penetrating through the side wall of the second tube beam 5 is also provided.

[0050] It should be noted that the inner diameters of the first tube beam 1 and the second tube beam 5 can be determined according to the diameters of the front fender frame tube beam and the rear fender frame tube beam of the tested vehicle. In addition, the number and size of the threaded holes on the first tube beam 1 and the second tube beam 5 can be set by those skilled in the art according to actual needs, and are not limited in the embodiments of the present application.

[0051] Furthermore, in order to facilitate the connection between the first tube beam 1 and the front fender frame tube beam or the rear fender frame tube beam of the vehicle under test, and the connection between the second tube beam 5 and the rear fender frame tube beam or the front fender frame tube beam of the vehicle under test, the threaded holes on the first tube beam 1 can be distributed away from the first connecting rod 2, and the threaded holes on the second tube beam 5 can be distributed away from the second connecting rod 4.

[0052] In some embodiments, the first tubular beam 1, the first connecting rod 2, the limiting rod 3, the second connecting rod 4 and the second tubular beam 5 are all made of aluminum alloy materials, thereby ensuring that the quality and rigidity of the slip ring positioning rod fixing device of the six-component force meter of the center and rear axle wheels can meet the requirements.

[0053] It is understandable that in certain scenarios where there is no requirement for mass and rigidity, the aluminum alloy material may be replaced by other materials whose lifting mass and / or rigidity are weaker than that of the aluminum alloy material, for example, it may be replaced by iron.

[0054] In some embodiments, in certain scenarios where there is no requirement for stiffness, the first connecting rod 2 and the second connecting rod 4 may be telescopic rods to adapt to different types of wheels.
