Technical Field

[0001] This utility model belongs to the field of loader manufacturing technology, and in particular relates to a gearbox mounting bracket. Background Technology

[0002] A loader is a type of construction machinery widely used in highway, railway, building, port, and mining projects. It is mainly used for loading bulk materials such as soil, sand, gravel, and coal. The gearbox is one of the main power components of a loader.

[0003] To improve the vibration resistance of the transmission after installation and to prevent the transmission from separating or detaching under severe vibration, shock absorbers are usually installed on the frame. The shock absorbers are connected to the frame by brackets to perform the vibration damping function.

[0004] For example, patent CN214465972U provides a loader gearbox mounting structure, which consists of a left mounting plate, a right mounting plate, and an upper mounting plate mounted on the loader frame. The lower end of a left bracket is connected to the left mounting plate, and the upper end of the left bracket is connected to the upper mounting plate. A first shock absorber assembly is provided between the left bracket and the left mounting plate, and a second shock absorber assembly is provided between the left bracket and the upper mounting plate. The lower end of a right bracket is connected to the right mounting plate, and the upper end of the right bracket is connected to the upper mounting plate. A fourth shock absorber assembly is provided between the right bracket and the right mounting plate, and a third shock absorber assembly is provided between the right bracket and the upper mounting plate. The left side of the gearbox is connected to the left bracket, and the right side of the gearbox is connected to the right bracket, thereby achieving the connection between the gearbox and the frame.

[0005] However, this method involves multiple mounting plates and brackets, which takes up a lot of space and is not suitable for some compact loaders. Utility Model Content

[0006] In view of the defects or deficiencies in the prior art, this utility model provides a gearbox mounting bracket that can reduce the space occupied by the loader gearbox while ensuring the gearbox's shock absorption effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An embodiment of this utility model provides a gearbox mounting bracket, including a front bracket. Two front brackets are provided and symmetrically arranged between the two side walls of the vehicle frame. Two fixing blocks are symmetrically arranged on the upper surface of the front brackets, and the two fixing blocks are spaced apart by a set distance.

[0009] Furthermore, the upper surface of the fixing block is provided with a first bolt hole, which is fixedly connected to the two side ears of the gearbox shock absorber by bolts.

[0010] Furthermore, the height of the fixing block is greater than the distance between the shock absorber ear plate and the bottom surface of the shock absorber.

[0011] Furthermore, the front support is n-shaped, including a support plate and side plates disposed on both sides of the support plate, the support plate and the side plates being integrally formed.

[0012] Furthermore, the support plate is placed horizontally, with the bottom of both side plates in contact with the bottom surface of the vehicle frame.

[0013] Furthermore, it also includes two rear supports, which are symmetrically arranged between the two side walls of the frame.

[0014] Furthermore, the rear support is placed horizontally, and one side wall of it is fixedly connected to the inner wall of the frame.

[0015] Furthermore, a reinforcing plate is provided between the inner wall of the frame and the bottom surface of the rear support.

[0016] Furthermore, the longitudinal section of the rear support is U-shaped, and a mounting groove is provided on the side away from the inner wall of the frame, which is adapted to the gearbox shock absorber.

[0017] Furthermore, the upper surface of the rear support is provided with a plurality of second bolt holes, which are symmetrically arranged on both sides of the mounting groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention features two fixed blocks on the upper surface of the front support, with a set distance between them, allowing the shock absorber at the front end of the gearbox to be placed between the two fixed blocks. By providing a mounting groove on the rear support, the shock absorber at the rear end of the gearbox can be placed in the mounting groove, thus not affecting the shock absorption effect. It eliminates the need for multiple mounting plates and brackets to connect the shock absorber to the frame, reducing the space occupied by the gearbox installation. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] A typical embodiment of this utility model is as follows: Figure 1 and Figure 4 As shown, a gearbox mounting bracket includes a front bracket 1 and a rear bracket 2. Two front brackets 1 and two rear brackets 2 are provided and symmetrically fixed between the two side walls of the frame 3. The front bracket 1 is connected to the shock absorber 4 at the front end of the bottom of the gearbox, and the rear bracket 2 is connected to the shock absorber 4 at the rear end of the bottom of the gearbox, thereby achieving support and fixation of the gearbox.

[0027] like Figure 2 As shown, the front support 1 is n-shaped, including a support plate 101 and side plates 102 disposed on both sides of the support plate 101. The support plate 101 and the side plates 102 are integrally formed. The support plate 101 is placed horizontally to fix the gearbox shock absorber 4. The bottom of the two side plates 102 are in contact with the bottom surface of the frame 3 to improve the support strength of the front support 1.

[0028] The upper surface of the support plate 101 is provided with two fixing blocks 103, which are spaced apart by a set distance. The upper surface of the fixing block 103 is provided with a first bolt hole 104, which is used to fix the fixing block 103 to the two side plates of the gearbox shock absorber 4 by bolts. The two fixing blocks 103 form a storage space for the gearbox shock absorber 4. When the side plates of the gearbox shock absorber 4 are connected to the fixing blocks 103 by bolts, the gearbox shock absorber 4 can be placed between the two fixing blocks 103. The height of the fixing blocks 103 is greater than the distance between the side plates of the shock absorber 4 and the bottom surface of the shock absorber 4. Thus, the fixing blocks 103 support the gearbox shock absorber 4 and prevent the gearbox shock absorber 4 from contacting the front support 1, which would affect the shock absorption effect.

[0029] like Figure 3 As shown, the rear support 2 is a flat plate structure and is placed horizontally. One side wall of the rear support 2 is fixedly connected to the inner wall of the frame 3. A reinforcing plate is provided between the inner wall of the frame 3 and the bottom surface of the rear support 2 to enhance the support strength of the rear support 2.

[0030] The longitudinal section of the rear support 2 is U-shaped. A mounting groove 201 is provided on the side away from the inner wall of the frame 3. The mounting groove 201 is adapted to the gearbox shock absorber 4. Multiple second bolt holes 202 are provided on the upper surface of the rear support 2. The multiple second bolt holes 202 are symmetrically arranged on both sides of the mounting groove 201. The second bolt holes 202 are corresponding to the through holes on the ear plates of the gearbox shock absorber 4. Thus, the gearbox shock absorber 4 and the rear support 2 are fixedly connected by bolts. When fixing, the gearbox shock absorber 4 is placed in the mounting groove 201 to avoid the shock absorber 4 from contacting the rear support 2 and affecting the damping effect. At this time, the through holes on the ear plates on both sides of the gearbox shock absorber 4 correspond to the second bolt holes 202. The shock absorber 4 and the rear support 2 are fixedly connected by bolts.

[0031] This invention features two fixed blocks on the upper surface of the front support, with a set distance between them, allowing the shock absorber at the front end of the gearbox to be placed between the two fixed blocks. By providing a mounting groove on the rear support, the shock absorber at the rear end of the gearbox can be placed in the mounting groove, thus not affecting the shock absorption effect. It eliminates the need for multiple mounting plates and brackets to connect the shock absorber to the frame, reducing the space occupied by the gearbox installation.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
