Description

Technical Field

[0001] The utility model relates to the technical field of forklift driving wheels, and particularly relates to an installation structure of a forklift driving wheel. Background Art

[0002] The driving wheel is one of the main parts for a forklift to move. It is usually directly connected to the power source of the forklift. Due to road conditions or operation problems, the driving wheel needs to be regularly inspected and replaced to avoid the forklift being unable to move due to driving wheel failures.

[0003] After retrieval, the patent document with the publication number CN112753527A provides a driving wheel installation mechanism: The invention discloses a driving wheel installation and fixing structure, including a motor. A stepped support seat is sleeved on the output shaft of the motor. A chain driving wheel is sleeved on the stepped shaft of the stepped support seat. A limiting component adapted to the outer end face of the chain driving wheel is provided on the stepped shaft of the stepped support seat. A locking structure passing through the stepped support seat and connecting with the output shaft of the chain saw motor is provided on the end face of the stepped shaft of the stepped support seat. The driving wheel installation and fixing structure of the invention is convenient for disassembly and assembly. The chain driving wheel is independently fixed on the stepped shaft in a connection mode, that is, when disassembling and assembling the chain driving wheel, it is not necessary to disassemble the locking structure at the outer end of the stepped support seat. The chain driving wheel is a vulnerable part and needs to be frequently disassembled and assembled. It is easy to replace and maintain in the later stage; a structure with better force bearing, more reliable quality and more stable product performance is provided.

[0004] During the use of the above technical solution, the driving wheel can only travel on a relatively flat road surface during travel. When there is a high threshold or obstacle on the road surface, the driving wheel of a traditional electric forklift cannot cross the obstacle, and then it needs to be transported, thus increasing unnecessary labor. At the same time, during the long-term driving process of the existing driving wheel, some sundries will adhere to the wheel, resulting in poor stability during the wheel travel.

[0005] Therefore, it is very necessary to invent an installation structure of a forklift driving wheel to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide an installation structure of a forklift driving wheel, so that the driving wheel can cross obstacles such as thresholds through the cooperation of a driving motor and an obstacle crossing mechanism, and solve the problem that in the prior art, the driving wheel of an electric forklift cannot cross obstacles and then needs to be transported, thus increasing unnecessary labor.

[0007] To achieve the above object, the present utility model provides the following technical solution: A forklift drive wheel mounting structure includes a drive motor. On one side of the drive motor, there is an obstacle crossing mechanism. The obstacle crossing mechanism includes a drive wheel disposed on one side of the drive motor. A gear ring is fixedly connected to the side of the drive wheel close to the drive motor. A connecting gear is meshed with the top of the gear ring. The outer side of the connecting gear is rotatably connected to a fixed frame. The top of the fixed frame is fixedly connected to a U-shaped frame. At the bottom of both ends of the U-shaped frame, auxiliary wheels are rotatably connected. The diameter of the auxiliary wheels is smaller than that of the drive wheel. The angle of the drive wheel is raised by the auxiliary wheels to facilitate the drive wheel to cross obstacles such as thresholds.

[0008] Preferably, two sets of transmission belts are sleeved on the outer sidewall of the transmission shaft of the connecting gear. One end of the transmission belt away from the connecting gear is wrapped around a driven wheel. The driven wheel is rotatably connected to the inner sidewall of the U-shaped frame. A brush is fixedly connected to the outer sidewall of the driven wheel and the brush contacts the outer sidewall of the drive wheel. The drive wheel and the gear ring drive the driven wheel and the brush to clean the drive wheel.

[0009] Preferably, a stepped support seat is installed at the output end of the drive motor. Four positioning pin holes are provided on the side of the stepped support seat away from the drive motor. A positioning pin is installed inside the positioning pin hole. The positioning pin is connected to the stepped support seat by the cooperation of the positioning pin and the positioning pin hole.

[0010] Preferably, a locking nut is attached to the side of the drive wheel away from the drive motor. A locking bolt is threadedly connected to one side of the locking nut. The locking bolt is threadedly connected to the inner side of the stepped support seat. The connection between the drive wheel and the stepped support seat is achieved by the cooperation of the locking nut and the locking bolt.

[0011] Preferably, two sliding rods are fixedly connected to the top of the U-shaped frame. A buffer spring is sleeved on the outer side of the sliding rod. The bottom end of the buffer spring is fixedly connected to the top of the U-shaped frame. The buffer spring buffers the vibration transmitted by the U-shaped frame.

[0012] Preferably, a connecting seat is fixedly connected to the top of the sliding rod. A fixing bolt is threadedly connected to the edge of the connecting seat. The U-shaped frame is connected to the vehicle body through the cooperation of the connecting seat and the fixing bolt.

[0013] In the above technical solution, the technical effects and advantages provided by the present utility model are:

[0014] 1. Through the cooperation of the drive motor and the obstacle crossing mechanism, the drive wheel drives the gear ring to rotate, and the gear ring drives the connecting gear to rotate, so that the connecting gear drives the two transmission belts and the driven wheel to rotate to realize the cleaning of the surface of the drive wheel by the brush, and the auxiliary wheel and the U-shaped frame are used in cooperation to assist the drive wheel to cross the threshold;
