Description

An electric steering four-way electric forklift body structure

Technical field:

The invention relates to forklift components, in particular to an electric steering four-way electric forklift body structure, which belongs to the field of mechanical products.

Background technique:

In recent years, as the country advocates and attaches great importance to saving energy consumption and protecting the environment, compared with diesel and gasoline forklifts, electric forklifts are extremely prominent in terms of fuel saving and environmental protection, and have become the focus and development direction of domestic manufacturers.

At present, there are very few domestic enterprises producing four-way electric forklifts. There are two structural types of four-way electric forklifts in the world: four-point four-way electric forklifts and three-point four-way electric forklifts. The main manufacturers of four-point four-way electric forklifts include Hubtex and Baumann, and the main manufacturers of three-point four-way electric forklifts include Combilift and Omegalift. But these several structures all have defects such as low durability, high complexity, and various parts.

Therefore, it is assumed to provide a new type of electric four-way electric forklift. In terms of structure, the four-way electric forklift is basically the same as the reach-type forklift. The mast is located between the front and rear wheels. The legs are equipped with supporting wheels at the front end of the inserted legs. The fork can move forward and backward along with the mast in the longitudinal direction of the forklift. When the fork is unloading, the fork is stretched out, and after the fork unloads the goods, the fork returns to the middle position close to the car body, thereby greatly improving the stability of the forklift. Different from the reach truck, the two load-bearing wheels at the front end of the fork legs of the four-way electric forklift can be turned by 90° through the steering mechanism. When the rear wheel turns 90°, the entire forklift can change from the state of front and rear driving to left and right driving on the spot, which is equivalent to a side fork.

The main technological innovations are: 1. EPS electric steering technology, easy to operate; 2. The forklift can realize four-way driving, which greatly improves the maneuverability of the forklift and requires a small passageway for work. For example, when working in warehouses and other places, it can greatly save the space for storing goods.

In order to realize this forklift successfully, the driving wheel assembly must be capable of universal rotation and have a certain degree of power, and the structural design of the vehicle body is particularly important.

Invention content:

The purpose of the present invention is to provide a body structure of an electric steering four-way electric forklift. By installing a driving wheel assembly at the rear end of the vehicle body and a load-bearing wheel structure that can be controlled by an oil pump in front of the vehicle body, the forklift can realize four directions. Driving in the same direction greatly improves the maneuverability of the forklift, and the passage required for work is small; when working in warehouses and other places, it can greatly save the space for storing goods. And the design structure of the body is simple, the mechanical pressure distribution is reasonable, and the long-term service life can be guaranteed.

The technical scheme adopted in the present invention is:

A body structure of an electric steering four-way electric forklift, including a body: a vertical plate is provided at the rear end of the vehicle body, a baffle plate is installed on the side of the vertical plate, a rear extension plate is installed in the middle of the vertical plate, and a rear extension plate is installed on the rear extension plate. There is a driving wheel assembly; the front end of the vehicle body has left and right forks, and front universal wheels are installed at the front ends of the left and right forks, and electric oil pumps are installed at the lower ends of the left and right forks, and each electric oil pump is connected to the corresponding front universal wheels.

The driving wheel assembly has a driving mounting plate, a driving motor is mounted on the upper end of the driving mounting plate, a reduction box is installed on the lower end of the driving mounting plate, a driving wheel is installed on the lower end of the reducing box, and the output shaft of the driving motor passes through the driving mounting plate And connected to the input end of the reduction box, the output end of the reduction box is connected to the driving wheel; the steering motor is installed on the top of the driving installation plate, the gear is fixed on the outer wall of the upper end of the reduction box, and the output shaft at the lower end of the steering motor passes through the driving installation plate and is connected to the To the driving gear, the driving gear and the gear are meshed with each other, the reduction box can rotate 360°, the output shaft of the steering motor drives the driving gear to rotate, and the driving gear drives the gear to rotate, thereby driving the reduction box to rotate as a whole.

Compared with prior art, the beneficial effect of the present invention is:

The invention installs the driving wheel assembly at the rear end of the vehicle body, and installs the load-bearing wheel structure that can be controlled by the oil pump in front of the vehicle body, so that the forklift can drive in four directions, greatly improving the maneuverability of the forklift, and the passage required for work is small. ; When working in warehouses and other places, it can greatly save the space for storing goods. And the design structure of the body is simple, the mechanical pressure distribution is reasonable, and the long-term service life can be guaranteed.
