[0020] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0021] Example

[0022] See also Figure 1-5 ,The utility model provides a technical solution: a forklift motor drive system;

[0023] This project aims to provide a forklift motor drive system that is beneficial for increasing the power of forklifts. Existing forklifts are prone to insufficient power when carrying heavy goods.

[0024] Based on the above issues, the components in this case include a forklift body 1, an assembly plate 2 is installed on the rear side of the forklift body 1, T-shaped slide grooves 3 are provided on both sides of the assembly plate 2, and limited position slideways 4 are provided on the outer sides of the T-shaped slide grooves 3. A lifting frame 5 is provided on the front side of the assembly plate 2, and a motor drive device 6 is installed on the lower side of the lifting frame 5. Drive wheels 7 are provided on both sides of the motor drive device 6;

[0025] Ear seats 8 are provided on both sides of the motor drive device 6, a driving member 9 is embedded on one side of the ear seat 8, the driving end of the driving member 9 is connected to the active gear 10, and the other side of the ear seat 8 is connected to the fastening component through a bearing. A hydraulic push rod 11 connected to the assembly plate 2 is provided on the outer side of the limiting slide 4, and the driving end of the hydraulic push rod 11 is connected to the ear seat 8 through a connecting block 12;

[0026] The fastening assembly includes a sliding seat 13, which is slidably connected to the T-shaped slide 3. Spring rods 14 are connected to both sides of the front end of the sliding seat 13. One end of the spring rod 14 is connected to a fastening block 15. The other side of the ear seat 8 is rotatably connected to a screw rod 16 through a bearing. One end of the screw rod 16 is connected to a driven tooth 17. A threaded hole is opened in the middle part of the fastening block 15, and the screw 16 is threadedly connected to the threaded hole.

[0027] It should be noted that when the forklift body 1 is carrying heavy goods and there is a lack of power, the hydraulic push rod 11 operates, driving the lifting frame 5 and the motor drive device 6 to descend through the connecting block 12 and the ear seat 8. At the same time, the distance sensor 20 senses the distance between the motor drive device 6 and the ground. After the motor drive device 6 reaches a predetermined distance, the hydraulic push rod 11 stops running, the driving wheel 7 comes into contact with the ground, and at the same time, the ear seat 8 drives the sliding seat 13 to slide inside the T-shaped slide 3 through the screw 16, the fastening block 15 and the spring rod 14.

[0028] At this time, the driving member 9 is running, and the active teeth 10 cooperate with the driven teeth 17 to drive the screw 16 to rotate. Since the screw 16 is threadedly connected to the threaded hole in the middle part of the fastening block 15, the action of the thread can drive the fastening block 15 to move as a whole, and make the first rough layer 18 on the top of the fastening block 15 tightly contact with the second rough layer 19 on the inner wall of the limiting slide 4. Under the dual action of friction and the hydraulic push rod 11, the lifting frame 5 can be fixed. Among them, the spring rod 14 is used to guide the fastening block 15 to prevent the position of the fastening block 15 from shifting;

[0029] Then the motor drive device 6 is operated to drive the drive wheel 7 to rotate, thereby increasing the power of the forklift during the cargo handling process, increasing the overall climbing ability of the forklift, increasing the cargo handling effect, and preventing dangerous situations such as slippage;

[0030] The screw 16 is driven to rotate by meshing the active teeth 10 with the driven teeth 17, thereby avoiding direct connection between the screw 16 and the driving end of the driving member 9. When the fastening block 15 is in close contact with the inner wall of the limiting slide 4, a radial pulling force is generated on the driving member 9, which may easily cause damage to the driving member 9.

[0031] Dovetail grooves are provided on both sides of the assembly plate 2. The rear side of the lifting frame 5 is slidably connected to the dovetail grooves through dovetail blocks. The cooperation between the dovetail grooves and the dovetail blocks can increase the stability of the lifting frame 5 during the lifting process.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
