Description
Technical Field
[0001] This invention relates to the field of vehicle testing technology, specifically to a testing device for vehicle transmission components. Background Technology
[0002] In vehicle development, durability and performance testing of components such as the front suspension, rear suspension, and powertrain requires testing via a transmission test platform. Existing technologies connect the output wheel of the transmission device to a rotation test device to detect power input and output. However, since vehicle transmission devices utilize universal joints for transmission, and the performance of universal joints varies at different angles, existing transmission test platforms cannot accurately test the performance of the transmission device under different universal joint angles and vibration amplitudes, nor can they accurately simulate various vehicle driving conditions.
[0003] Therefore, it is necessary to provide a testing device for vehicle transmission components to solve the problems mentioned in the background art. Summary of the Invention
[0004] To achieve the above objectives, the present invention provides the following technical solution: a test device for a vehicle transmission component, comprising a fixed bracket, a rotating bracket hinged to one side of the fixed bracket, a hydraulic cylinder provided between the fixed bracket and the rotating bracket, a horizontal bar provided on the rotating bracket, and vertical bars provided at both ends of the horizontal bar, with a rotating disk rotatably provided on the inner side of each vertical bar.
[0005] Furthermore, preferably, a slide rail is fixed on the rotating bracket, and the crossbar is slidably connected to the slide rail and can be locked.
[0006] Furthermore, preferably, both ends of the crossbar are retractable and lockable.
[0007] Furthermore, preferably, the vertical bar and the horizontal bar are slidably connected and can be locked.
[0008] Furthermore, as a preferred embodiment, the rotating disk is provided with a connecting flange, and the connecting flange has a connecting hole on its circumference corresponding to the output wheel of the transmission device.
[0009] Furthermore, as a preferred embodiment, two connecting pins are fixed in the rotating disk, and sliding grooves are provided on both sides of the connecting flange, with the sliding grooves being slidably confined within the connecting pins.
[0010] Furthermore, as a preferred embodiment, a screw is rotatably provided between the two connecting pins of the rotating disk, and a nut is fixed on the side of the connecting flange near the rotating disk, and the nut is threadedly connected to the screw.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] In this invention, the transmission performance of the transmission device at different angles can be tested by changing the angle of the rotating bracket using a hydraulic cylinder. The eccentricity between the rotating disk and the connecting flange can be adjusted by rotating the screw to simulate the vibration effect when the output wheel of the transmission device rotates, thereby testing the performance of the transmission device at different amplitudes.

[0016] Please see Figure 1 In this embodiment of the invention, a testing device for a vehicle transmission component includes a fixed bracket 1, with a rotating bracket 2 hinged to one side of the fixed bracket 1. A hydraulic cylinder 3 is provided between the fixed bracket 1 and the rotating bracket 2. A crossbar 5 is provided on the rotating bracket 2, and vertical bars 6 are provided at both ends of the crossbar 5. A rotating disk 7 is rotatably provided inside each vertical bar 6. When the drive device 8 of the transmission component is fixed on the fixed bracket 1, and the output wheel of the transmission device 9 is connected to the two rotating disks 7, the transmission performance of the transmission device 9 at different angles can be tested by changing the angle of the rotating bracket 2 through the hydraulic cylinder 3.
[0017] In this embodiment, a slide rail 4 is fixed on the rotating bracket 2, and the crossbar 5 is slidably connected to the slide rail 4 and can be locked. This allows it to accommodate transmission devices 9 of different lengths.
[0018] In this embodiment, the crossbar 5 is telescopic and lockable at both ends, thus accommodating transmission devices 9 of different widths.
[0019] In this embodiment, the vertical rod 6 and the horizontal rod 5 are slidably connected vertically and can be locked. This allows for adaptation to transmission devices 9 of different heights.
[0020] Please see Figure 2 In this embodiment, the rotating disk 7 is provided with a connecting flange 10, and the connecting flange 10 has a connecting hole on its circumference corresponding to the output wheel of the transmission device 9. The output wheel of the transmission device 9 can be fixedly connected to the connecting flange 10 by bolts.
[0021] In this embodiment, two connecting pins 11 are fixed in the rotating disk 7, and sliding grooves 12 are provided on both sides of the connecting flange 10, and the sliding grooves 12 are slidably confined in the connecting pins 11. That is to say, the connecting pins 11 enable the rotating disk 7 and the connecting flange 10 to move eccentrically and transmit torque.
[0022] In this embodiment, a screw 13 is rotatably provided between the two connecting pins 11 of the rotating disk 7, and a nut is fixed on the side of the connecting flange 10 near the rotating disk 7, and the nut is threadedly connected to the screw 13. That is to say, by rotating the screw 13, the eccentricity between the rotating disk 7 and the connecting flange 10 can be adjusted to simulate the vibration effect when the output wheel of the transmission device 9 rotates, thereby testing the performance of the transmission device 9 under different amplitudes.
[0023] In practice, the drive unit 8 of the transmission component is fixed on the fixed bracket 1. The positions of the horizontal bar 5 and the vertical bar 6 are adjusted so that the connecting flange 10 is aligned with the output wheel of the transmission device 9. The output wheel of the transmission device 9 is fixedly connected to the connecting flange 10 by bolts. The hydraulic cylinder 3 can change the angle of the rotating bracket 2 to test the transmission performance of the transmission device 9 at different angles. By rotating the screw 13, the eccentricity between the rotating disk 7 and the connecting flange 10 can be adjusted to simulate the vibration effect when the output wheel of the transmission device 9 rotates, thereby testing the performance of the transmission device 9 under different amplitudes.
[0024] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
