[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The present invention creatively detects two wheel-side reducers in parallel, and the two wheel-side reducers serve as the load of the other party, which satisfies the synchronous detection of the two wheel-side reducers and conveniently realizes the detection of the reducer's no-load torque and noise under rated load.

[0023] One embodiment of the present invention provides a parallel wheel-mounted reducer detection device comprising two detection units independently driven by servo motors, enabling simultaneous detection of two wheel-mounted reducers. During detection, the two rubber-coated wheels contact each other, creating friction during movement. By adjusting the mounting distance between the two wheel-mounted reducers, friction can be eliminated, enabling detection of the reducers' no-load torque and noise under rated load.

[0024] like Figure 1 As shown, the parallel wheel-side reducer detection device of this embodiment includes: a first detection unit 1 and a second detection unit 2 used in conjunction with the first detection unit 1, and the first detection unit 1 and the second detection unit 2 are connected through a fixing frame 3.

[0025] The fixing bracket 3 is used to realize the connection between the first detection unit 1 and the second detection unit 2, so as to realize parallel detection of the two wheel-side reducers.

[0026] The fixing frame 3 includes a first frame body 31, a second frame body 32, and a connecting assembly 33 that connects the first and second frames 31, 32 and defines the assembly spacing between the first and second frames 31, 32. Thus, by selecting an appropriate connecting assembly 33, the assembly spacing between the first and second frames 31, 32 can be flexibly adjusted.

[0027] In one embodiment, the connection assembly 33 includes a first connection block 331 and a second connection block 332. The upper portions of the first and second frames 31, 32 are detachably connected via the first connection block 331, and the lower portions of the first and second frames 31, 32 are detachably connected via the second connection block 332. By selecting the appropriate sizes of the first and second connection blocks 331, 332, the assembly spacing between the first and second frames 31, 32 can be controlled, thereby adjusting the center-to-center spacing between the first and second detection units 1, 2.

[0028] Accordingly, the upper and lower sides of each frame body are formed with mounting surfaces, each with mounting holes suitable for bolting. Thus, the upper portions of the first and second frames 31, 32 are bolted to the first connecting block 331 via a set of bolts, while the lower portions of the first and second frames 31, 32 are bolted to the second connecting block 332 via another set of bolts.

[0029] like Figure 2 As shown, in order to facilitate the installation and fixation of the first detection unit 1 and the second detection unit 2, a first groove 311 suitable for assembling the servo motors in the first detection unit 1 and the second detection unit 2 is formed on the first and second frames 31 and 32. At the same time, in order to facilitate the installation and fixation of the wheel-side reducer A to be tested, a second groove 312 suitable for assembling the wheel-side reducer A to be tested is also formed on the first and second frames 31 and 32. At this time, the second groove 312 and the first groove 311 are arranged front and back, and the two form a step structure. In this way, the assembly and fixation of the two are facilitated when the servo motor drives the wheel-side reducer. The above-mentioned first groove 311 can be a square groove, and the second groove 312 can be a circular groove.

[0030] The first detection unit 1 and the second detection unit 2 are used together to perform synchronous detection on two wheel-side reducers. The first detection unit 1 is mounted and fixed by the first frame 31, and the second detection unit 2 is mounted and fixed by the second frame 32. Any detection unit 1 or 2 includes: a servo motor 11 and a wheel hub 12. The servo motor 11 can be connected to the wheel-side reducer A to be tested, and the wheel hub 12 can be driven by the wheel-side reducer driven by the servo motor 11 to pivot. In order to facilitate the transmission connection between the servo motor 11 and the wheel-side reducer A to be tested, the two are matched through a flange structure.

[0031] As described above, by selecting a suitable connecting component 33, the assembly spacing between the first and second frames 31 and 32 can be flexibly adjusted, and the center spacing between the first detection unit 1 and the second detection unit 2 is adjusted by the assembly spacing between the first and second frames 31 and 32. That is, by changing the center spacing, the wheel hub 12 driven by the wheel-side reducer can interact with each other to simulate the radial load in the wheel hub 12 in actual working conditions. By increasing the center distance, the wheel hub 12 driven by the wheel-side reducer can be disengaged and become two independent units. By adjusting the speed of the servo motor 11, the operating noise of the drive unit at different speeds can be tested. Accordingly, the center distance is greater than or equal to the diameter of the wheel hub 12.

[0032] In addition, the circumferential surface of the wheel hub 12 can also be coated with a colloid. In this case, the first detection unit 1 includes a wheel hub rubber coating 13, which is coated on the circumferential surface of the wheel hub 12 of the first detection unit 1. The second detection unit 2 includes a wheel hub rubber coating 13, which is coated on the circumferential surface of the wheel hub 12 of the second detection unit. In one embodiment, the wheel hub rubber coating 13 is made of polyurethane, a material with high hardness and wear resistance. In this case, the center distance between the first detection unit 1 and the second detection unit 2 is greater than or equal to the sum of the diameter of the wheel hub 12 and the thickness of the wheel hub rubber coating 13.

[0033] To sum up, the parallel wheel-side reducer detection device of the present invention can detect the no-load torque and noise under rated load of the reducer. By installing two wheel-side reducers in parallel for detection, simulated load testing can be achieved. At the same time, the center distance can be adjusted to test the noise and no-load torque at no load, which solves the difficult and complex application scenarios in the production and testing of reducers. Technical bottlenecks.
