Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and more specifically to a left suspension assembly for an automotive transmission. Background Technology

[0002] As a crucial component of a car, the transmission's structure and performance parameters not only influence vehicle performance, but proper installation is also essential for ensuring these superior performance characteristics. Transmission installation is primarily achieved through mounting brackets, typically in several locations. These different mounting brackets are first installed onto the vehicle body, and then the corresponding parts of the transmission are secured using their respective bracket supports. The transmission mounting system includes the body-mounted bracket, the transmission mounting bracket, and damping components. In existing automotive transmission mounting technology, the damping components are integrally molded with the body-mounted bracket, which severely limits the manufacturing of these components. This results in poor damping performance, negatively impacting the transmission's damping effect and ultimately reducing vehicle performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a left suspension assembly for an automobile gearbox, wherein the damping component of the left suspension assembly for the automobile gearbox is a separate structure from the body connecting bracket, and the damping component has a good damping effect, thereby improving the damping performance of the automobile gearbox.

[0004] The technical solution of this utility model is to provide a left suspension assembly for an automotive transmission with the following structure: a body connecting bracket, a transmission connecting bracket, and a vibration damping component; the transmission connecting bracket has a mounting hole, the vibration damping component is press-fitted into the mounting hole, and the vibration damping component is fixedly connected to the wall of the mounting hole; one end of the transmission connecting bracket is embedded in the mounting groove of the vibration damping component, and the other end of the transmission connecting bracket is fixedly connected to the groove wall of the mounting groove; a vibration damping pad is provided on the side of the body connecting bracket near the transmission connecting bracket, and the vibration damping pad abuts against the transmission connecting bracket.

[0005] With the above structure, the left suspension assembly of the automotive transmission of this utility model has the following advantages compared with the prior art:

[0006] Because the damping component of the left suspension assembly of the automotive transmission of this utility model is a separate structure from the body connecting bracket, the manufacturing of the damping component is less restricted, which can greatly improve the damping effect of the damping component, thereby improving the vibration damping performance of the vehicle's gearbox. A damping pad is provided on one side of the body connecting bracket, which abuts against the transmission connecting bracket and has a damping effect on the transmission connecting bracket, further improving the vibration damping performance of the transmission.

[0007] As an improvement, the vibration damping component and the mounting hole wall are fixedly connected to each other via a snap-fit ​​and slot structure. This structure ensures a more reliable connection between the vibration damping component and the mounting hole wall.

[0008] As an improvement, a limiting step is provided on the side of the mounting hole near the gearbox connecting bracket, and one side of the vibration damping component is limited by the limiting step. With this structure, the limiting step has a limiting effect on the vibration damping component, ensuring reliable installation.

[0009] As an improvement, a positioning groove is provided on the abutting surface where the limiting step abuts against the vibration damping component, and a positioning protrusion is provided on the side wall of the vibration damping component, the positioning protrusion being embedded in the positioning groove. With this structure, the positioning groove and the positioning protrusion have a positioning function, resulting in more reliable installation and higher fitting accuracy.

[0010] As an improvement, the lower side of one end of the vehicle body connecting bracket is provided with an outwardly protruding bumper, and the damping pad is fixedly connected to the side wall of the bumper. The side wall of the damping pad is provided with multiple anti-slip protrusions. With this structure, the anti-slip protrusions can effectively prevent slippage.

[0011] As an improvement, the gearbox connecting bracket includes a frame and a connecting rod. The connecting rod is connected to the upper end of one side of the frame and is integrally formed with the frame. The end of the connecting rod is inserted into the mounting groove of the vibration damping component. One side wall of the frame abuts against the vibration damping pad. With this structure, the gearbox connecting bracket has a simple structure and is easy to assemble.

[0012] As an improvement, the end of the connecting rod is provided with a protruding rib, and the wall of the mounting groove is provided with a groove, in which the protruding rib is embedded. With this structure, the protruding rib and the groove have a positioning function, resulting in more reliable installation and higher fitting accuracy.

[0013] As an improvement, a battery support bracket is provided on one side of the vehicle body connecting bracket, and the battery support bracket is integrally formed with the vehicle body connecting bracket. With this structure, the battery support bracket can support the battery, expanding the function of the left suspension assembly of the vehicle's transmission. Attached Figure Description
