Technical Field

[0001] The present invention relates to the technical field of reducer detection equipment, and in particular to a reducer detection device for new energy vehicles. Background Art

[0002] A reducer is an independent component consisting of a gear drive, worm drive, or gear-worm drive enclosed in a rigid housing. It is commonly used as a reduction gear between the prime mover and the working machine. In recent years, new energy vehicles have experienced rapid development. New energy vehicles use unconventional automotive fuels as a power source (or use conventional automotive fuels with new onboard power units). These vehicles incorporate advanced technologies in vehicle power control and drive, resulting in advanced technical principles, new technologies, and new structures.

[0003] Reducers are usually used in the transmission system of new energy vehicles. As people's demand for comfort and controllability of new energy vehicles increases, manufacturers' performance requirements for reducers are also getting higher and higher. Therefore, reducers used in new energy vehicles will undergo loading testing before leaving the factory, usually through a set of dedicated loading test benches.

[0004] However, during the process of loading and testing the reducer, the existing loading and testing bench can basically only perform loading and testing on one type of reducer and cannot perform loading and testing on different types of reducers, resulting in low applicability of the loading and testing bench.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a speed reducer detection device for new energy vehicles, referring to Figure 1 , including a detection platform 1, on which a drive motor 4 and a first sensor 5 are provided. The drive motor 4 and the first sensor 5 are both fixed to the detection platform 1 through a base, and the output shaft of the drive motor 4 is coaxially fixedly connected to the rotating shaft of the first sensor 5.

[0035] Reference Figure 1 and Figure 2 A mounting base 3 is fixedly mounted on the detection platform 1. The mounting base 3 is located on the side of the first sensor 5 facing away from the drive motor 4. The detection platform 1 is provided with a plurality of movable slots 12 along its length. A plurality of movable blocks 13 are bolted to the bottom surface of the mounting base 3 and placed in the movable slots 12. A position adjustment mechanism 7 is provided on the mounting base 3, and a reducer 2 is placed on the position adjustment mechanism 7. The input shaft of the reducer 2 and the rotating shaft of the first sensor 5 are provided with a coaxial connection mechanism 8 and are coaxially fixedly connected via the coaxial connection mechanism 8.

[0036] Reference Figure 1 and Figure 2, the drive motor 4 is started, which outputs a preset power, which is transmitted to the reducer 2 via the first sensor 5, driving the reducer 2 to rotate. The first sensor 5 can detect the torque and speed of the input shaft of the reducer 2. The sliding movement of the movable block 13 within the movable groove 12 causes the mounting base 3 to move along the length of the detection platform 1 on the detection platform 1, facilitating the adjustment of the horizontal position of the mounting base 3.

[0037] Reference Figure 1 and Figure 2 The position adjustment mechanism 7 includes a lifting assembly 72, which includes a hydraulic cylinder 721, a lifting plate 722 and a plurality of telescopic guide rods 723. The hydraulic cylinder 721 is vertically fixed on the top surface of the mounting base 3, and the lifting plate 722 is fixedly mounted on the piston rod of the hydraulic cylinder 721. One end of the plurality of telescopic guide rods 723 is fixedly connected to the top surface of the mounting base 3, and the other end is fixedly connected to the bottom surface of the lifting plate 722. A locking structure is fixedly mounted on each telescopic guide rod 723.

[0038] Reference Figure 1 and Figure 2 The extension and retraction of the piston rod of the hydraulic cylinder 721 can drive the lifting plate 722 to rise and fall. The multiple telescopic guide rods 723 can guide the lifting plate 722 during the lifting process, improving the stability of the lifting plate 722 during the lifting. After the lifting plate 722 is raised and lowered, the multiple telescopic guide rods 723 are locked and fixed using a locking structure, so that the multiple telescopic guide rods 723 can stably support the lifting plate 722.

[0039] Reference Figure 2 and Figure 3 A placement plate 9 for the reducer 2 is movably mounted on the lifting plate 722. In this embodiment, the placement plate 9 is an electromagnetic suction plate. A plurality of guide grooves 10 are defined on the top surface of the lifting plate 722, and are arranged perpendicularly to the movable grooves 12. A plurality of guide blocks 11 are integrally formed on the bottom surface of the electromagnetic suction plate and are placed within the guide grooves 10.

[0040] Reference Figure 2 and Figure 3 The movement of the guide block 11 within the guide slot 10 causes the electromagnetic suction plate and reducer 2 to move horizontally along the length of the movable slot 12, facilitating adjustment of the horizontal position of the reducer 2. When powered, the electromagnetic suction plate generates an electromagnetic suction force, enabling various types of reducers 2 to be fixedly attached to the plate.

[0041] Reference Figure 2 and Figure 3The position adjustment mechanism 7 also includes a translation assembly 71, which includes an electric push rod 711, a guide rod 712, a first connecting block 713, and a second connecting block 714. The first connecting block 713 and the second connecting block 714 are fixedly mounted on opposite side walls of the electromagnetic suction plate, and the line connecting the first connecting block 713 and the second connecting block 714 is perpendicular to the guide groove 10. The electric push rod 711 is fixed to the lifting plate 722, and the output end of the electric push rod 711 is fixedly connected to the first connecting block 713. The guide rod 712 is fixedly mounted on the lifting plate 722 and is located on the side of the electromagnetic suction plate facing away from the electric push rod 711. The guide rod 712 is arranged parallel to the output end of the electric push rod 711 and passes through the second connecting block 714.

[0042] Reference Figure 1 and Figure 2 Activating the electric push rod 711 drives the first connecting block 713 to move horizontally, thereby driving the electromagnetic suction plate and the reducer 2 mounted thereon to move horizontally, helping to adjust the horizontal position of the reducer 2. As the electromagnetic suction plate moves, the guide rod 712 guides the second connecting block 714, thereby guiding the movement of the electromagnetic suction plate.

[0043] Reference Figure 4 and Figure 5 The coaxial connection mechanism 8 includes a coupling 81 and a detection component 82. The detection component 82 includes a laser emitter 821, a laser receiver 822 and two mounting structures 823. Each mounting structure 823 includes a mounting belt 8231, a mounting frame 8232 and two mounting rods 8233. The two mounting belts 8231 are fixedly sleeved on the input shaft of the reducer 2 and the rotating shaft of the first sensor 5, respectively. The mounting frame 8232 is fixedly connected to the mounting belt 8231. The two mounting rods 8233 are fixed on the mounting frame 8232. The laser emitter 821 is fixed on the two mounting rods 8233 located on the input shaft of the reducer 2. The laser receiver 822 is fixed on the two mounting rods 8233 located on the rotating shaft of the first sensor 5.

[0044] Reference Figure 4 and Figure 5 When the input shaft of the reducer 2 is fixedly connected to the rotating shaft of the first sensor 5, the two shafts are fixedly connected via a coupling 81. Simultaneously, a laser emitter 821 emits a laser beam toward a laser receiver 822. The position of the laser beam on the laser receiver 822 can detect the deviation between the two shafts, thereby facilitating adjustment of the coaxiality of the two shafts and improving the coaxial connection between the input shaft of the reducer 2 and the rotating shaft of the first sensor 5.

[0045] Reference Figure 1A second sensor 14 is coaxially connected to the output shaft of the reducer 2, and the second sensor 14 is fixedly placed on the detection platform 1 via a base. A loading assembly 6 is provided at the end of the second sensor 14 facing away from the reducer 2. The loading assembly 6 includes a gearbox 62 and a loader 61. In this embodiment, the loader 61 is a magnetic powder brake. Both the gearbox 62 and the magnetic powder brake are fixedly placed on the detection platform 1 via a base. The gearbox 62 is coaxially connected to the second sensor 14, and the magnetic powder brake is coaxially connected to the end of the gearbox 62 facing away from the second sensor 14. When the magnetic powder brake is activated, it outputs a loading torque, and loads the reducer 2 through adjustment of the gearbox 62 and transmission from the second sensor 14, facilitating loading detection of the reducer 2.

[0046] The implementation principle of the embodiment of the present application is as follows: when performing loading tests on different types of reducers 2, the reducer 2 to be tested is placed on the electromagnetic suction plate. By sliding the movable block 13 in the movable groove 12, the mounting seat 3 and the reducer 2 are moved along the length direction of the detection platform 1. At the same time, the operation of the electric push rod 711 is coordinated to move the electromagnetic suction plate and the reducer 2 along the width direction of the detection platform 1, thereby adjusting the horizontal position of the reducer 2. Afterwards, the electromagnetic suction plate is energized to fix the reducer 2 on the electromagnetic suction plate. The vertical position of the reducer 2 is then adjusted by the hydraulic cylinder 721 so that the reducer 2 is coaxial with the first sensor 5 and the second sensor 14.

[0047] The input shaft of the reducer 2 is fixedly connected to the rotating shaft of the first sensor 5, and the output shaft of the reducer 2 is fixedly connected to the rotating shaft of the second sensor 14 via a coupling 81. Simultaneously, a laser emitter 821 emits a laser beam toward a laser receiver 822. The position of the laser beam on the laser receiver 822 can detect the deviation between the two shafts, thereby facilitating adjustment of the coaxiality of the two shafts. This helps improve the coaxial connection between the input shaft of the reducer 2 and the rotating shaft of the first sensor 5, thereby ensuring the loading detection effect of the reducer 2.

[0048] The drive motor 4 is started and can output a preset power, which is transmitted to the reducer 2 through the first sensor 5, driving the reducer 2 to rotate. At the same time, the magnetic powder brake is activated, outputting a loading torque. The load is applied to the reducer 2 through the adjustment of the gearbox 62 and the transmission of the second sensor 14, facilitating the load detection of the reducer 2.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
