Detailed implementation manners

[0025] It should be noted that the following detailed descriptions are all illustrative and are intended to provide a further description of the present utility model. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0026] Next, in combination with the attached drawings, the present utility model will be described in detail. An embodiment of the present utility model discloses a transmission installation assembly, as Figure 1 shown, including a first installation mechanism and a second installation mechanism. The first installation mechanism is arranged at both ends of the upper part of the transmission assembly 8, and the second installation mechanism is arranged at the lower part of the transmission assembly 8; the first installation mechanism includes a first mounting plate 2, and several first shock absorbers 4 are arranged at the upper end of the first mounting plate 2; the second installation mechanism includes a second mounting plate 7, and several second shock absorbers 11 are arranged at both ends of the second mounting plate 7.

[0027] There are two first mounting mechanisms. First mounting plates 2 are symmetrically arranged at the upper end of the transmission assembly 8. The first mounting plates 2 are used to support two positions at the upper end of the transmission assembly 8 and are provided with two support points. A support plate is arranged on the first mounting plates 2 for mounting shock absorbers. A second mounting plate 7 is arranged at the lower end of the transmission assembly 8. The second mounting plate 7 is used to support two positions at the lower end of the transmission assembly 8 and is provided with two support points. Second shock absorbers 11 are symmetrically arranged at both ends of the second mounting plate 7. The first shock absorber 4 and the second shock absorber 11 have the same structure and are both shock absorbers dedicated to the installation of the transmission assembly 8. The shock absorbers are used to absorb the vibrations generated by the bumps during the driving of the loader, thereby effectively preventing the transmission assembly 8 from loosening and ensuring the stability of the installation. Two support points are arranged at the upper and lower ends of the transmission assembly 8 for installation. Compared with the integrated four-point installation with the engine, the installation method of separately installing the left and right support points has more uniform force and is more convenient to install, and can effectively avoid the damage of the housing caused by the integrated installation.

[0028] As Figure 1 shown, several fixing bolts 1 are arranged at intervals at one end of the first mounting plate 2. The first mounting plate 2 and the transmission assembly 8 are connected by the fixing bolts 1. Two fixing bolts 1 are arranged on the first mounting plate 2, and corresponding mounting holes are arranged on the transmission assembly 8. The first mounting plate 2 and the transmission assembly 8 are connected by the fixing bolts 1; As Figure 3 shown, several fixing bolts 1 are arranged at intervals at both ends of the second mounting plate 7. The fixing bolts 1 on the second mounting plate 7 are located at the side of the second shock absorber 11. The second mounting plate 7 and the transmission assembly 8 are connected by the fixing bolts 1. Two fixing bolts 1 are arranged at each end of the second mounting plate 7, and corresponding mounting holes are arranged on the transmission assembly 8. The second mounting plate 7 and the transmission assembly 8 are connected by the fixing bolts 1; Through the arrangement of the fixing bolts 1, the first mounting mechanism and the second mounting mechanism are connected to the transmission assembly 8, and then the connection with the frame 9 is realized, making the connection more firm. Among them, the fixing bolts 1 can adopt hexagon flange bolts.

[0029] As Figure 1 shown, a first support vertical plate 14 is arranged on the first mounting plate 2. A first support horizontal plate 15 is arranged in the middle of the first support vertical plate 14. The first shock absorber 4 is arranged at the upper and lower ends of the first support horizontal plate 15. A first washer 3 is arranged on the upper part of the first shock absorber 4 at the upper end of the first support horizontal plate 15. The first support horizontal plate 15 and the first shock absorber 4 are connected by a first bolt 5 and a first locking nut 6. The first bolt 5 sequentially passes through the first washer 3, the first shock absorber 4 at the upper end, the first support horizontal plate 15, the first shock absorber 4 at the lower end, and the frame 9, and a first locking nut 6 is arranged at the end of the first bolt 5.

[0030] As Figure 3As shown, second support vertical plates 16 are provided at both ends of the second mounting plate 7. A second support horizontal plate 17 is provided in the middle of the second support vertical plates 16. Second shock absorbers 11 are provided at the upper and lower ends of the second support horizontal plate 17. A second washer 10 is provided above the second shock absorber 11 at the upper end of the second support horizontal plate 17. The second support horizontal plate 17 and the second shock absorbers 11 are connected by a second bolt 12 and a second locking nut 13. The second bolt 12 sequentially passes through the second washer 10, the second shock absorber 11 at the upper end, the second support horizontal plate 17, the second shock absorber 11 at the lower end, and the vehicle frame 9. A second locking nut 13 is provided at the end of the second bolt 12.

[0031] The first support horizontal plate 15 and the first support vertical plate 14 are used to mount the first shock absorber 4. The first shock absorbers 4 are provided at both ends of the first support vertical plate 14. When the loader vibrates during driving, the vibration is transmitted to the vehicle frame 9, and then the vehicle frame 9 transmits it to the shock absorbers. At this time, the first shock absorber 4 dampens the vibration at one end of the transmission assembly, thereby preventing the connection position from loosening. The second support horizontal plate 17 and the second support vertical plates 16 are used to mount the second shock absorbers 11. The second shock absorbers 11 are provided at both ends of the second support vertical plates 16 to absorb the vibration force at the other end of the transmission assembly 8 and prevent the connection position from loosening.

[0032] The first shock absorber 4, the first support horizontal plate 15, and the vehicle frame 9 are connected by a first bolt 5, a first washer 3, and a first locking nut 6, so that the first shock absorber 4 can absorb the vibration force of the vehicle frame 9. The second shock absorber 11, the second support horizontal plate 17, and the vehicle frame 9 are connected by a second bolt 12, a second washer 10, and a second locking nut 13, so that the second shock absorber 11 absorbs the vibration force of the vehicle frame 9. The first bolt 5 and the second bolt 12 can be hexagon head bolts, and the first locking nut 6 and the second locking nut 13 can be hexagon locking nuts. Openings are provided at the upper and lower ends of the second mounting plate 7. The openings are used to avoid the components on the transmission assembly 8, so that the second mounting plate 7 can be mounted on the transmission assembly 8. The second mounting plate 7 is provided as an integral structure, which improves the load-bearing capacity.

[0033] During installation, first install the first mounting plate 2 at both ends of the upper part of the transmission assembly 8 through the fixing bolts 1, and then install the second mounting plate 7 at the lower end of the transmission assembly 8 through the fixing bolts 1. The first support cross plate 15, the first support vertical plate 14, the second support cross plate 17 and the second support vertical plate 16 are all prefabricated on the mounting plate; install the first shock absorber 4 at both ends of the first support cross plate 15, and connect the first shock absorber 4, the first support cross plate 15 and the vehicle frame 9 through the first bolt 5, the first washer 3 and the first locking nut 6; install the second shock absorber 11 at both ends of the second support cross plate 17, and connect the second shock absorber 11, the second support cross plate 17 and the vehicle frame 9 through the second bolt 12, the second washer 10 and the second locking nut 13, then the installation of the transmission installation assembly can be completed, and further support the transmission assembly 8 to make the force more uniform.
