Problems solved by technology

[0002] The steering system of the forklift can control the driving direction of the forklift according to the driver's wishes. At present, the steering wheel of the steering system of most forklifts has a turning angle of about 50 degrees. In many cases, the aisle of the warehouse is very narrow, and it is difficult for the forklift to turn and the line of sight is not good. , and the existing steering system cannot meet the perfect requirements
The steering of the existing forklift requires a large steering space, so it is not conducive to the accurate and fast positioning of the forklift, and it is inconvenient for the driver to operate. The steering wheels of the steering system of the existing forklift are all in the direction of the driver's back, and the seat is low. The direction of the steering wheel cannot be seen, and the driver does not know where the last direction was when changing frequently

Embodiment 1

[0021] Example 1: A steering system of a forklift, such as figure 1 As shown, it includes a motor 1, a reducer 2, a front steering unit 3, and a rear steering unit 4. The output shaft of the motor is connected to the input shaft of the reducer. The reducer has dual output shafts, one of which is Connected to the front steering unit, and another output shaft connected to the rear steering unit;

[0022] The rear steering unit includes a first transmission shaft 5, two transmission shafts 10, a commutator 6, two transmissions 7, two pillar plates 8 and two rear wheels 9. One end of the first transmission shaft is connected to the One output shaft of the reducer is connected, and the other end of the first transmission shaft is connected to the input shaft of the commutator, and the commutator has parallel dual output shafts, and is connected to the side transmission shafts respectively. One end of the side drive shaft is connected to the input shaft of the transmission, the output ...

Embodiment 2

[0028] Embodiment 2: A steering system of a forklift, such as image 3 As shown, it has a similar structure to Embodiment 1, except that the front steering unit includes a second drive shaft 12, two side drive shafts 10, a commutator, two drives, two upright plates and two For the front wheel, one end of the second transmission shaft is connected with an output shaft of the reducer, and the other end of the second transmission shaft is connected with the input shaft of the commutator, and the commutator has a parallel The dual output shafts are respectively connected to one end of the side transmission shaft, the other end of the side transmission shaft is connected to the input shaft of the transmission, and the output shaft of the transmission is connected to the upper end of the column plate , The lower end of each column plate is connected with the front wheel, the torque of the motor is transmitted to the second drive shaft through the reducer, and the direction is changed...

Abstract

The invention discloses a forklift steering system, which comprises a motor, a reducer, a front steering unit and a rear steering unit. The motor is connected with the reducer, the reducer is providedwith double output shafts, one output shaft is connected with the front steering unit, and the other output shaft is connected with the rear steering unit; the rear steering unit comprises a first driving shaft, two side driving shafts, a commutator, two drivers, two vertical column plates and two rear wheels, one end of the first driving shaft is connected with the corresponding output shaft ofthe reducer, and the other end of the first driving shaft is connected with an input shaft of the commutator; the commutator is provided with parallel double output shafts which are connected with oneends of the side driving shafts correspondingly, the other ends of the side driving shafts are connected with input shafts of the drivers, output shafts of the drivers are connected with the upper ends of the vertical column plates correspondingly, and the lower ends of the vertical column plates are connected with the wheels correspondingly. According to the forklift steering system, the direction of a direction wheel can be clearly saw in real time and the direction of the next step is quickly reflected, not only can longitudinal driving be achieved, but also horizontal driving can be achieved, and the forklift steering system is suitable for various narrow places.

Description

Technical field [0001] The present invention relates to the technical field of vehicle steering systems, in particular to a forklift steering system. Background technique [0002] The steering system of the forklift can control the driving direction of the forklift according to the driver’s wishes. At present, the turning angle of the steering wheel of the steering system of most forklifts is about 50 degrees, and often the warehouse lanes are very narrow, the forklift is difficult to turn, and the line of sight is not good. , And the existing steering system cannot meet the perfect requirements. Existing forklift steering requires a large steering space, so it is not conducive to accurate and rapid positioning of the forklift and inconvenient for the driver to operate. The steering wheel of the existing forklift steering system is all in the direction of the driver’s back, and the seat is low. The direction of the steering wheel cannot be seen, and the driver does not know wher...
