Secondly, the walking device is large in size and can roll crops. Although the size of the walking device of the existing mini-tiller is small, the mini-tiller can be used for carrying out field operation in the middle and later periods of crops, the matching power is small, the production efficiency is low, the mini-tiller is not suitable for field management in the middle and later periods of high-stalk crops, and the mini-tiller also has the defects of high labor intensity of drivers, poor safety and stability and the like.
At present, a transmission system of an existing mobile platform is usually only used for leveling roads, the required turning space is large, the transmission is not stable, and the operation on field roads such as ridges is very limited.
Disclosure of Invention
This patent provides a carry on three motor collaborative transmission systems on field moving platform to the not enough that prior art exists, can realize the moving platform's of complicated topography such as ridge stable transmission and nimble turn control.
The scheme of this patent solution problem is: the rear wheel drives the front wheel to steer, namely the rear wheel provides power to drive the platform to move, and the front wheel controls the steering of the platform.
The rear wheel drives, and the storage battery supplies power to the motor; the motor is connected with the speed reducer to reduce the rotating speed; further, the power is transmitted to the second transmission shaft through belt transmission by a V belt pulley which is coaxial with the output shaft of the speed reducer; furthermore, the small chain wheel positioned on the second transmission shaft transmits power to the rear wheel through chain transmission, so that rear wheel driving is realized. The controller can adjust and control the rotating speed of the motor to realize the change of the driving speed.
The front wheels are steered, and the storage battery supplies power to the motor; the motor is connected with the speed reducer; a small bevel gear is arranged on an output shaft of the speed reducer, the output shaft is a stepped shaft, and a bearing set is arranged on the output shaft to fix the bevel gear; further power is transmitted to the front wheels through a pair of bevel gear sets, and steering of the front wheels is achieved. When the rotating speeds of the two motors are different, the deflection angles of the two front wheels are also different, namely the deflection angles of the left wheel and the right wheel of the front wheel are respectively controlled to control steering.
The beneficial effect of this patent is.
1. This patent adopts three gear motor, wherein controls turning to of front wheel through controlling two rotational speeds that turn to the motor, can control different radius through the differential of difference and turn, and the special topography between furthest has utilized the field ridge carries out the operation, improves labor efficiency. The rest of the driving motors are adjusted by the controller to transmit power to the rear wheels through the belt transmission chain, namely, the rear wheel driving.
2. The driving force of the vehicle is transmitted to the wheels through the motor, the speed reducer, the belt transmission and the chain transmission, and the transmission stability is fully guaranteed.
3. The belt transmission is adopted, the belt transmission structure is simple, the cost is low, the use and the maintenance are convenient, and the flexibility and the elasticity are good. And the belt transmission can buffer and absorb vibration, thereby ensuring the stability of the whole transmission system.
