Description

Technical Field

[0001] The utility model relates to the technical field of automotive transmission shift testing, and particularly relates to a mounting bracket. Background Art

[0002] An automotive transmission is a key component in a vehicle's power transmission system. Its main function is to adjust the matching between the engine output torque and the wheel speed to provide appropriate power and fuel economy. The shift performance of the transmission directly affects the vehicle's comfort, acceleration performance, fuel economy, and reliability. Therefore, automotive manufacturers and engineers have been working on improving the shift performance of automotive transmissions.

[0003] In order to measure the instantaneous change of the output speed during shifting and understand the change process of the shift speed, when an automotive transmission is undergoing a shift test, the automotive transmission needs to be fixed on a test bench and cooperate with an encoder to record test data. However, when the transmission is undergoing high and low speed conversion, vibrations will occur at the output end of the transmission and the fixture for fixing the transmission, making the data recorded by the encoder for the shift performance of the transmission inaccurate and affecting the authenticity of the test. For this reason, we propose a mounting bracket to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a mounting bracket to solve the problem that when the transmission is undergoing high and low speed conversion, vibrations will occur at the output end of the transmission and the fixture for fixing the transmission, making the data recorded by the encoder for the shift performance of the transmission inaccurate.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: A mounting bracket includes a support plate and a transition plate. The support plate is arranged at the upper end of the test bench, and the support plate is used for mounting the transition plate. The transition plate is arranged on the side of the support plate, and the transition plate is used for fixing different transmissions. The output end of the transmission rotates through the transition plate and the support plate. An installation frame is arranged at one end of the support plate away from the transition plate. A fixing member is arranged at one end of the installation frame away from the support plate. An encoder is arranged at one end of the fixing member away from the installation frame, and the output end of the encoder rotates through the fixing member. An installation groove is formed in the middle of the installation frame, a bearing is arranged in the installation groove, a connecting shaft is arranged in the middle of the bearing, and a connecting member is arranged between the input end of the encoder and the connecting shaft. Through the connecting member, the output end of the transmission and the input end of the encoder rotate synchronously. A flange is arranged at one end of the connecting shaft away from the encoder, and the flange is clamped with the output end of the transmission.

[0006] The beneficial effects of this solution are as follows: By fixedly installing the support plate at the upper end of the test bench, the stability of the support plate is increased. At the same time, the transmission housing is fixed in cooperation with the transition plate, thereby increasing the stability of the transmission housing during gear shifting, reducing the vibration of the gearbox housing during gear shifting. The mounting bracket is used to fix the bearing, and at the same time, it is flange-connected to the output end of the transmission, and the power of the transmission is transmitted in cooperation with the connecting shaft and the connecting piece. Since the bearing is fixedly installed in the mounting bracket, the stability of the output end of the transmission can be further increased in cooperation with the connecting shaft, reducing the vibration of the output end during gear shifting of the transmission, thereby increasing the authenticity of the test data recorded by the encoder.

[0007] Preferably, as an improvement, the connecting piece includes a PUV tube and two clamps. One end of the PUV tube is sleeved on the outer wall of the input end of the encoder, and the other end is sleeved on the outer wall of the connecting shaft. The two clamps are respectively clamped at both ends of the PUV tube.

[0008] The beneficial effects are as follows: The two ends of the PUV tube are respectively fixed on the outer walls of the input end of the encoder and the connecting shaft through two clamps, which is used to transmit the kinetic energy of the transmission. At the same time, the PUV tube has a low price and is convenient to obtain materials, which can effectively reduce the cost of the gear shifting test of the transmission.

[0009] Preferably, as an improvement, the mounting bracket is set in a U shape, and the two fulcrums of the mounting bracket are detachably connected to the support plate.

[0010] The beneficial effects are as follows: By setting the mounting bracket in a U shape, the contact area between the mounting bracket and the support plate can be increased, the stability of the mounting bracket can be increased, so as to better fix the bearing and prevent the output end from vibrating during gear shifting of the transmission.

[0011] Preferably, as an improvement, the fixing piece is set in a U shape, and the two fulcrums of the fixing piece are detachably connected to the mounting bracket.

[0012] The beneficial effects are as follows: Setting the fixing piece in a U shape can increase the stability of the encoder operation, thereby improving the authenticity of the gear shifting test data of the transmission.

[0013] Preferably, as an improvement, internal splines are provided on the inner wall of the flange, and threaded holes are symmetrically penetrated on the outer wall of the flange.

[0014] The beneficial effects are as follows: The internal splines provided on the inner wall of the flange are used to engage with the output end of the transmission, so that the gear shifting test of the transmission can be carried out quickly. When the internal splines on the inner wall of the flange do not match, the output end of the transmission can be fixed by the threaded holes provided on the outer wall of the flange in cooperation with bolts, so that the gear shifting test of the transmission can be carried out quickly.

[0021] Embodiment

[0022] The embodiment is basically as shown in the attached Figures 1-4 as shown, such as Figure 1 and Figure 2 shown, a mounting bracket includes a support plate 1 and a transition plate 2. The support plate 1 is fixedly installed on the upper end of the test bench through bolts. The support plate 1 is used to install the transition plate 2. The transition plate 2 is fixedly installed on the back of the support plate 1 through bolts. The transition plate 2 is used to fix different transmissions. The output end of the transmission rotates through the transition plate 2 and the support plate 1. The front end of the support plate 1 is fixedly installed with a mounting frame 3 through bolts. As shown in Figure 3 shown, the mounting frame 3 is arranged in a U-shape. The two fulcrums of the mounting frame 3 are detachably connected to the support plate 1. The front end of the mounting frame 3 is fixedly installed with a fixing member 4 through bolts. The fixing member 4 is also arranged in a U-shape. The two fulcrums of the fixing member 4 are detachably connected to the mounting frame 3. The front end of the fixing member 4 is fixedly installed with an encoder 5, and the output end of the encoder 5 rotates through the fixing member 4. An installation groove is opened in the middle of the mounting frame 3, and a bearing 6 is fixedly installed in the installation groove. As shown in Figure 4 shown, a connecting shaft 7 is clamped in the middle of the bearing 6. The connecting shaft 7 can rotate in the middle of the bearing 6. A connecting piece 8 is provided between the input end of the encoder 5 and the connecting shaft 7. Through the connecting piece 8, the output end of the transmission and the input end of the encoder 5 rotate synchronously. The connecting piece 8 includes a PUV pipe 10 and two clamps 11. One end of the PUV pipe 10 is sleeved on the outer wall of the input end of the encoder 5, and the other end is sleeved on the outer wall of the connecting shaft 7. The two clamps 11 are respectively clamped at both ends of the PUV pipe 10. A flange 9 is fixedly installed at the end of the connecting shaft 7 away from the encoder 5. Internal splines are provided on the inner wall of the flange 9, and threaded holes 12 are symmetrically penetrated through the outer wall of the flange 9. The flange 9 is clamped with the output end of the transmission.

[0023] The specific implementation process is as follows:

[0024]

[0025] When conducting a shifting test on the transmission, first place the transmission on the test bench, and then fix the housing at the front end of the transmission to the transition plate 2. At this time, the output end of the transmission penetrates through the transition plate 2 and the support plate 1 and is clamped with the internal spline on the inner wall of the flange 9. If the internal spline on the inner wall of the flange 9 does not match, the output end of the transmission can also be fixed through the cooperation of bolts and the threaded holes 12. Then, cut a PUV tube 10 of an appropriate length, and respectively sleeve the two ends of the PUV tube 10 on the outer walls of the connecting shaft 7 and the input end of the encoder 5, and then fix the two ends of the PUV tube 10 through the clamp 11, so as to connect the output end of the transmission with the input end of the encoder 5. When conducting a shifting test on the transmission, since the transmission housing is fixedly connected to the transition plate 2, the vibration of the transmission housing during shifting can be reduced. At the same time, the connecting shaft 7 in the bearing 6 can further reduce the vibration of the output end of the transmission during shifting, and thus the real data of the encoder 5 recording the shifting performance of the transmission can be improved. The above are only the embodiments of the present invention, and the common specific technical solutions and / or characteristics and other common knowledge are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners and other records in the specification can be used to interpret the content of the claims.
