AI Technical Summary
In the prior art, during testing, the gearbox cannot be installed consistently with the real engine, resulting in insufficient elastic support at the rear end during vibration, which cannot effectively suppress the tail jump, causing stress at the fixed end connection and damage to the gearbox.
A rigid support structure of the transmission is adopted, including a support base, a rigid suspension plate and a transmission mounting plate. It is connected to the transmission through a rigid suspension plate, and the vibration power is transmitted to the support base, eliminating additional force, realizing the fixed front and rear ends, simulating the installation status of the real vehicle.
Effectively suppress tail jumps, avoid stress at the fixed end connection, ensure that the gearbox has the same effect as the real car in the bench test state, and protect the gearbox from damage.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of automotive transmissions, and particularly to a transmission support structure. Background Art
[0002] In a real vehicle, the transmission is directly connected to the engine. An elastic support is used at the engine end, and the transmission is installed on a test bench, where a tooling plate is used for connection at the bench end.
[0003] In the prior art, in the test installation state of the transmission, since the front end of the transmission cannot be installed in the same way as the real vehicle engine, the original front end is installed on the tooling plate and then connected and fixed to the test bench, and the rear end is supported by the elastic suspension of the engine, which is different from the real vehicle installation.
[0004] The disadvantages of the prior art are that when the test motor runs at high speed, there is a large vibration, and the elastic support at the rear end is not sufficient to overcome the tail jump. Since the front bench is fixed, it is bound to cause the force generated by the tail jump to act on the connection at the fixed end, damaging the transmission and failing to play the role of support and fixation and eliminating the acting force. Summary of the Utility Model
[0005] Therefore, in view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a transmission detection support structure that can support and fix and eliminate the acting force.
[0006] The technical solution of the utility model is a rigid support structure for a transmission. The support structure is connected to the transmission to be tested. The support structure includes a support base, a rigid suspension piece fixedly connected to the support base, and a part on the rigid suspension piece for the transmission to connect. At the other end of the support structure, there is a transmission mounting plate, and the transmission mounting plate is connected to a bench head frame.
[0007] According to the rigid support structure for a transmission of the utility model, screw holes are provided at the part on the rigid suspension piece for the transmission to connect.
[0008] According to the rigid support structure for a transmission of the utility model, the position of the rigid suspension piece and the position of the transmission are such that the vibration of the transmission acts on the support base.
[0009] According to the rigid support structure for a transmission of the utility model, the height at the connection between the support seat of the rigid suspension piece and the top of the transmission is adjusted to be horizontally on the same straight line. The position of the rigid suspension piece and the height of the transmission are adjusted to the horizontal position.
[0010] Advantageous Effects:
[0011] In the prior art, the elastic support and the gearbox are elastically connected, the gearbox tooling and the bench head frame are rigidly connected, the vibration of the gearbox is transmitted to the elastic support, and the acting force acts on the elastic support, so that the vibration force cannot be transmitted to the support seat. The rigid connection between the rigid support and the gearbox causes the vibration force of the gearbox to act on the rigid support and then be transmitted to the support base.
[0012] Since the test installation state of the gearbox cannot be the same as the actual vehicle installation at the front end because it cannot be connected to the engine of the actual vehicle. The front end must be fixedly connected to the bench, and the rear end is supported by the elastic suspension of the engine, so it is impossible to suppress the jumping. Therefore, it is now changed that the elastic support at the rear end is rigidly fixedly connected to the front bench, and both the front and rear ends are fixed and immovable. In this way, the tail jumping can be effectively suppressed, and the situation of force acting on the fixed end connection can be avoided, eliminating the generation of additional acting forces, achieving the same effect as the actual vehicle in the bench test state.
[0013] Adopting a rigid fixed support can effectively suppress the tail jumping and avoid the situation of force acting on the fixed end connection, eliminating the generation of additional acting forces. Description of the Drawings

[0016] In the figure, 1 - support base, 2 - rigid suspension piece, 3 - gearbox mounting plate, 4 - bench head frame. Detailed Implementation Manner
[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0018] As Figure 2 shown, the rigid support structure of the present invention includes a support base 1, a rigid suspension piece 2, a gearbox mounting plate 3, and a bench head frame 4.
[0019] During the test, the support structure is connected to the gearbox to be tested. This support structure includes a support base 1, a rigid suspension piece 2 is fixedly connected to the top of the support base 1, and a part for connecting the gearbox is provided on the rigid suspension piece 2. The other end of the support structure is provided with a gearbox mounting plate, and the gearbox mounting plate is connected to the bench head frame.
[0020] A screw hole is provided at the part for connecting the gearbox on the rigid suspension piece. This screw hole is used for fixedly connecting the gearbox.
[0021] The working process of the present invention is:
[0022] First, install the transmission onto the transmission mounting plate 3, and then install the transmission with the mounting plate onto the headstock 4 of the bench. After the fixation is completed, install the rigid suspension piece 2 at the rear end of the transmission and combine it with the support base 1. The position adjustment of the rigid support frame and the height position of the transmission are relatively important and need to be adjusted to an appropriate height. The height of the connection between the support seat of the rigid suspension piece and the top of the transmission is adjusted to be horizontally on the same straight line. Then connect the rigid suspension piece to the transmission so that the vibration of the transmission acts on the support base.
