Description

Technical Field

[0001] This utility model belongs to the field of transmission testing technology, specifically a novel mounting component for a synchronizer test bench adapted for reverse gear testing. Background Technology

[0002] With the rapid development of the automotive industry, manual transmissions (MT) remain widely used in passenger and commercial vehicles due to their simple structure, high reliability, and good fuel economy. Among these components, the synchronizer, as one of the core components of the MT, plays a crucial role in achieving smooth shifting and transmission efficiency. However, in reverse gear, due to the opposite direction of vehicle movement and driving torque, the synchronizer must withstand greater mechanical stress and frictional losses. In recent years, with the rise of new energy vehicles and the increasing performance requirements of traditional fuel vehicles, the technical research and optimization of synchronizer reverse gear testing has become an important topic for improving the overall performance of MTs.

[0003] During reverse gear testing, the synchronizer test bench needs to lock the intermediate shaft to simulate the vehicle's condition. However, the locking force of existing locking devices is provided by ground support. If the locking force is too large, and abnormal torsional force occurs during the test, the resulting shear force without any force relief will directly cause static torque in the transmission, damaging the transmission itself. Utility Model Content

[0004] To address the problems existing in the background technology, this utility model provides a novel installation component for a synchronizer test bench adapted for reverse gear testing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel synchronizer test bench with a mounting assembly for reverse gear testing, comprising a transmission rear housing, a flange adapter, a U-shaped locking mechanism, a movable base plate, and two movable supports;

[0006] The rear gearbox is engaged with one end of the flange adapter, and the other end of the flange adapter is clamped and fixed by a U-shaped locking mechanism. The two ends of the U-shaped locking mechanism are respectively connected to corresponding movable brackets. The two movable brackets are symmetrically arranged and both movable brackets are connected to a movable base plate.

[0007] The U-shaped locking mechanism includes two clamping units, each of which has three through holes. Each through hole is used in conjunction with a corresponding movable bracket, and each clamping unit has a rubber pad on its inner wall.

[0008] Each of the movable supports has three elongated holes at its vertical end that match the three through holes on the clamping unit, and each movable support has a through hole at its horizontal end that works with the movable base plate.

[0009] The movable base plate has an elongated hole that mates with the through holes on the two movable supports.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Balancing Locking and Protection: Under normal operating conditions, the U-shaped locking mechanism provides a stable locking effect through the friction generated by the clamping flange adapter. This design ensures the stability of the transmission during testing, allowing the synchronizer test to proceed smoothly. When excessive torsional force occurs during testing, if the torsional force exceeds the friction force, the flange adapter will rotate (i.e., slip) within the U-shaped locking mechanism. This rotation serves to relieve force, effectively protecting the intermediate shaft and gears inside the transmission from static torsion damage.

[0012] 2. Reduce potential damage: The mounting components of this utility model significantly reduce potential damage to the transmission by changing the source of the locking force (from ground support force to friction force). This design avoids static torsional damage to the transmission caused by excessive locking force when the torsional force is too large, thereby reducing testing and maintenance costs.

[0013] 3. High adaptability: Through the design of movable bracket and movable base plate, the mounting assembly of this utility model can adapt to a variety of different sizes of transmissions. This flexibility makes the mounting assembly have a wider range of application prospects in the field of transmission testing.

[0014] 4. Easy to operate: The installation and adjustment process is relatively simple, making it easy for test personnel to operate and maintain. Test personnel only need to assemble and adjust the rear gearbox, flange adapter, U-shaped locking mechanism, movable bracket and movable base plate according to the steps to complete the installation and fixation of the installation components.

[0015] 5. Improved testing efficiency and accuracy: Since the mounting components of this utility model can provide a stable locking effect and play a protective role when the torsional force is too large, the efficiency and accuracy of the test can be improved. Testers can conduct tests with more confidence without worrying about damage to the transmission caused by excessive locking force or torsional force.

[0016] In summary, this utility model has the advantages of combining locking and protection effects, reducing potential damage, strong adaptability, simple operation, and improving test efficiency and accuracy. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0024] This embodiment describes a novel synchronizer test bench installation assembly adapted for reverse gear testing, including a transmission rear housing 1, a flange adapter 2, a U-shaped locking mechanism 3, a movable base plate 5, and two movable brackets 4.

[0025] The rear gearbox 1 of the transmission is engaged with one end of the flange adapter 2, and the other end of the flange adapter 2 is clamped and fixed by the U-shaped locking mechanism 3. The two ends of the U-shaped locking mechanism 3 are respectively connected to the corresponding movable brackets 4. The two movable brackets 4 are symmetrically arranged, and both movable brackets 4 are connected to the movable base plate 5.

[0026] The U-shaped locking mechanism 3 includes two clamping units, each of which has three through holes. Each through hole is used in conjunction with a corresponding movable bracket 4, and each clamping unit has a rubber pad on its inner wall.

[0027] Each of the movable brackets 4 has three elongated holes at its vertical end that match the three through holes on the clamping unit, and each of the movable brackets 4 has a through hole at its horizontal end that works in conjunction with the movable base plate 5.

[0028] The movable base plate 5 has an elongated hole 2 that mates with the through holes 2 on the two movable brackets 4.

[0029] When using this invention, first, ensure that the rear gearbox 1 is securely fixed on the corresponding test bench. Then, carefully align and mesh the spline of the drive shaft inside the rear gearbox 1 with the spline of one end of the flange adapter 2. Next, place the other end of the flange adapter 2 between the two clamping units of the U-shaped locking mechanism 3, using the clamping units to hold and fix the flange adapter 2. Then, use three threaded rods to pass through the corresponding through holes 1 on the two clamping units, and pass the two ends of each threaded rod through the corresponding elongated holes 1 on the movable bracket 4. Adjust the U-shaped locking mechanism 3 to a suitable position by moving it up and down, and then fix it by threading the corresponding nuts to the two ends of the threaded rods. Finally, place the two movable brackets 4, which have been adjusted to their positions, on the movable base plate 5, so that the through holes 2 on the two movable brackets 4 correspond to the elongated holes 2 on the movable base plate 5, and adjust them to a suitable horizontal position. Subsequently, the movable base plate 5 is placed on the corresponding test bench 2. Bolts are then passed sequentially through the through hole 2 on the movable bracket 4, the elongated hole 2 on the movable base plate 5, and the mounting hole on the test bench 2, and tightened with nuts to complete the assembly of the entire mounting component. Under normal operating conditions, the U-shaped locking mechanism 3 provides a locking effect through the friction generated by clamping the flange adapter 2. This friction is precisely adjusted by the rubber pad and the tightness of the U-shaped lock to ensure that it is much smaller than the locking force originally provided by the ground support force, thereby effectively reducing potential damage to the transmission. When excessive torsional force occurs during the test, and this torsional force is greater than the friction force, the flange adapter 2 will rotate relative to the U-shaped locking mechanism 3 (i.e., slip). This rotation effectively converts the excessive torsional force into frictional heat energy, and the energy is further absorbed and dispersed by the buffering effect of the rubber pad, thereby playing a role in unloading the force and protecting the intermediate shaft and gears inside the transmission from static torsion damage.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
