Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive engineering technology, specifically to a performance testing device for hydraulic automatic transmissions. Background Technology
[0002] With the booming development of the automotive industry, hydraulic automatic transmissions are being used more and more widely in various vehicles. Their performance directly affects the vehicle's power, economy, comfort, and reliability. Therefore, accurate and comprehensive performance testing of hydraulic automatic transmissions is of paramount importance.
[0003] Currently, performance testing of the torque output shaft of hydraulic automatic transmissions is also particularly important. Common torque output shaft clamping devices have poor versatility and are difficult to adapt to different models and sizes of hydraulic automatic transmissions. Frequent clamp changes not only increase testing costs but also reduce testing efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a performance testing device for hydraulic automatic transmissions to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic automatic transmission performance testing device, comprising a base and clamping assemblies located at both ends of the base. An L-shaped support plate is fixedly installed in the middle of the outer wall of the base. A motor is installed at the included angle of the support plate. A transmission rod penetrating the support plate is fixedly connected to the output end of the motor. A first pulley is fixedly connected to the wall of the transmission rod. A transmission belt is driven through the groove of the first pulley. A second pulley is driven through the transmission belt and rotatably connected to the side wall of the support plate via a bearing. A clamping frame is fixedly connected to the outer wall of the second pulley. Clamping rings are provided at both ends inside the clamping frame. A slider is fixedly connected to the lower end of the outer ring wall of each clamping ring. A screw is rotatably embedded in the middle of the outer ring wall of the clamping ring.
[0006] Preferably, the clamping frame has two sliding grooves at both the top and bottom, and the sliders are locked in the sliding grooves.
[0007] Preferably, all the screws are threadedly connected to the outer end of the clamping frame.
[0008] Preferably, a handle is fixedly connected to one end of each screw, and the outer wall of each handle is provided with several grooves.
[0009] Preferably, the inner ring walls of the two clamping rings are coated with a rubber-based anti-slip coating.
[0010] Compared with existing technologies, the advantages of this invention are as follows: By using a motor to drive the clamping frame and torque output shaft to rotate via a transmission rod, pulley, and belt, the rotation state of the transmission during actual operation can be simulated, allowing direct detection of any abnormal noises or other issues during torque output shaft rotation. The device's design, utilizing a screw, slider, and groove, allows for flexible adjustment of the clamping ring position, enabling effective clamping of torque output shafts of different diameters. Compared to traditional single-specification clamping devices, frequent clamp replacements are unnecessary, improving the device's applicability to various models of hydraulic automatic transmissions.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-4 The present invention provides the following technical solution:
[0018] Example 1: A hydraulic automatic transmission performance testing device, including a base 1 and clamping components 11 located at both ends of the base 1.
[0019] When in use, the staff will first pick up the hydraulic automatic transmission housing and fix it on the base 1 using the clamping component 11 to prevent the hydraulic automatic transmission from shaking during testing, which could lead to errors in the test and affect the accuracy of the test.
[0020] Example 2: The technical solution of this example, which differs from Example 1, includes: an L-shaped support plate 2 fixedly installed in the middle of the outer wall of the base 1; a motor 21 installed at the included angle of the support plate 2; a transmission rod 22 passing through the support plate 2 fixedly connected to the output end of the motor 21; a first pulley 23 fixedly connected to the wall of the transmission rod 22; a transmission belt 24 drivingly connected to the groove of the first pulley 23; a second pulley 25 rotatably connected to the side wall of the support plate 2 via a bearing connected to the transmission belt 24; and a clamping frame 3 fixedly connected to the outer wall of the second pulley 25. Both ends of the frame 3 are provided with clamping rings 32. The lower end of the outer ring wall of the clamping ring 32 is fixedly connected with a slider 31. The middle of the outer ring wall of the clamping ring 32 is embedded and rotatably connected with a screw 33. The top and bottom ends of the clamping frame 3 are provided with two sliding grooves 301, and the sliders 31 are locked in the sliding grooves 301. The screws 33 are threaded through and connected to the outer end of the clamping frame 3. One end of the screws 33 is fixedly connected with a handle 34, and the outer wall of the handle 34 is provided with several grooves. The grooves can increase the friction of the handle 34. The inner ring wall of the two clamping rings 32 is coated with a rubber-based anti-slip coating.
[0021] In use, first place the torque output shaft inside the clamping frame 3, then rotate the handle 34 to drive the clamping ring 32 to move inward via the screw 33. The clamping ring 32 will slide along the slide groove 301 via the slider 31, thereby clamping torque output shafts of different diameters. The rubber-based anti-slip coating on the inner ring wall of the clamping ring 32 can increase the friction between the clamping ring 32 and the torque output shaft. Then start the motor 21 to drive the first pulley 23 to rotate via the transmission rod 22. The first pulley 23 drives the second pulley 25 to rotate via the transmission belt 24. The second pulley 25 will drive the torque output shaft to rotate via the clamping frame 3, thereby detecting whether there are any abnormal noises or other issues when the torque output shaft rotates.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
