Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklift structural devices, and in particular to a forklift drive unit structure. Background Technology
[0002] Forklifts play an indispensable role as essential material handling equipment in many fields such as logistics warehousing and industrial production. Their drive unit, as the core component of forklift operation, directly affects the forklift's performance, efficiency, and stability.
[0003] Traditional forklift drive unit structures often have numerous limitations. In terms of structural layout, the design of support components and output components in some drive units is inadequate, resulting in low space utilization, cumbersome installation and maintenance processes, and increased equipment maintenance costs and downtime. For example, the connection between the drive components and output components in some drive units is fixed, lacking flexibility and making it difficult to adapt to the adjustment requirements of drive direction and angle under different working conditions, thus limiting the forklift's ability to operate in complex environments.
[0004] In the power transmission stage, traditional drive unit structures may suffer from low power transmission efficiency. The connection between the motor and reducer is not optimized, easily generating vibration and impact during operation. This not only affects the smoothness of power transmission but also accelerates component wear and reduces equipment lifespan. Furthermore, the lack of effective buffering and shock absorption measures means that the impact force on the drive unit is directly transmitted to the vehicle body during forklift operation, affecting driving comfort and safety, and potentially damaging goods.
[0005] Furthermore, as the application scenarios for forklifts continue to expand, higher demands are being placed on the adaptability and reliability of drive units. For example, in some working environments that are sensitive to vibration and shock, drive units need to have good damping performance to reduce the impact of external factors on the drive system. However, existing forklift drive unit structures are often not perfect in terms of damping design, making it difficult to meet these special requirements.
[0006] In view of the problems existing in the prior art, this utility model proposes a novel forklift drive unit structure, which aims to improve the overall performance and reliability of the forklift drive unit by optimizing the structural design, improving the power transmission method and enhancing the buffer performance, so as to better adapt to the usage requirements under different working conditions.

[0045] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0046] like Figures 1 to 4 As shown in the figure, the present invention provides a forklift drive unit structure, including a fixing plate 100, a drive component 200, an adjustment component 300 and a buffer fixing device 400.

The output component 500 mainly includes a reducer 510 and a motor. The reducer 510 is directly mounted on the support member 110. The motor is connected to the reducer 510 to facilitate the reducer 510 to control the motor speed.
[0049] In this embodiment, the motor and the reducer 510 are connected by a flexible coupling.
[0050] In this embodiment, the support member 110 is mainly composed of a rotating member 111 and a fixing member 112. The rotating member 111 is mounted on the fixing plate 100 via an adjusting assembly 300. The rotating member 111 is rotatably mounted on the fixing plate 100 and rotates relative to the fixing plate 100. The fixing member 112 is vertically arranged on the rotating member 111. The fixing member 112 is connected to the rotating member 111 and is arranged vertically relative to the rotating member 111. A reducer 510 is arranged at one end of the fixing member 112 away from the rotating member 111. The driving member 200 is connected to the reducer 510.
[0051] In this embodiment, the adjustment component 300 mainly includes an adjustment drive 310, a first connector 320, and a second connector 330. The adjustment drive 310 is mounted on the fixed plate 100, and the first connector 320 is located at the output end of the adjustment drive 310. The second connector 330 is connected to the rotating component 111, and the second connector 330 is movably connected to the first connector 320. When the adjustment drive 310 is working, the first connector 320 drives the second connector 330 to move, thereby causing the rotating component 111 to rotate and adjusting the rotation angle of the support component 110. In this embodiment, the first connector 320 includes a drive gear, and the second connector 330 includes a driven gear. The drive gear and the driven gear mesh to achieve stable rotation adjustment of the rotating component 111.
[0052] To further improve the stability and cushioning performance of the forklift drive unit structure, a cushioning fixing device 400 is also provided on the fixed plate 100 in this embodiment. The fixed plate 100 is connected to the forklift via the cushioning fixing device 400. The cushioning fixing device 400 mainly includes a support column 410, a cushioning spring 420, a mounting plate 430, and an abutment member 440. The support column 410 is disposed on the fixed plate 100, and the cushioning spring 420 is sleeved on the support column 410, with one end of the cushioning spring 420 abutting against the fixed plate 100.

The mounting plate 430 is connected to the forklift. The abutment 440 is located at one end of the support column 410. The buffer spring 420 and the mounting plate 430 are both located between the fixing plate 100 and the abutment 440 to prevent the mounting plate 430 and the buffer spring 420 from detaching from the support column 410.

The radius of the buffer groove 433 is larger than the radius of the buffer spring 420. The end of the buffer spring 420 facing the mounting plate 430 is located within the buffer groove 433, thereby further improving the stability of the buffer spring 420 on the mounting plate 430. When the forklift experiences vibration and impact during operation, the buffer spring 420 can absorb and buffer the vibration and impact, reducing the impact of vibration and impact on the forklift drive unit structure and improving the smoothness and safety of the forklift operation.
[0055] In summary, the forklift drive unit structure provided by this utility model improves the overall performance and reliability of the forklift drive unit by optimizing the structural design, improving the power transmission method, and enhancing the buffer performance, so as to better adapt to the usage requirements under different working conditions.
