Embodiment Construction

[0081] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0082] Such as figure 1 As shown, a wheel-driven electric tractor includes a hood 1, an electric control box 2, an instrument panel 3, a steering wheel 4, a driver's seat 5, a rear battery pack 6, an electric suspension 7, a drive assembly 8, and a power output shaft 9. Driving wheel 10, wheel side reducer 11, front battery pack 12, vehicle frame assembly 13, front axle assembly 14 and steering wheel 15.

[0083] The hood 1 is fixed on the front end of the vehicle frame assembly 13 through a hinge. The vehicle frame assembly 13 includes a front vehicle frame and a rear vehicle frame, and the front and rear vehicle frames are fixed as one. The front frame is used to install the electric control box 2, the instrument panel 3, the steering wheel 4, the front battery pack 12 and the front axle assembly 14, and the rear frame is used to install...

Abstract

The invention belongs to the technical field of electric tractors, and particularly relates to a control method of a wheel edge driving electric tractor which comprises an electric cabinet (2), a rear battery pack (6), a driving assembly (8), a driving wheel (10), a wheel edge speed reducer (11), a front battery pack (12), a frame assembly (13), a front axle assembly (14) and a steering wheel (15). The form of wheel-side motor driving is adopted, a complex transmission mechanical structure of a traditional tractor is omitted, the driving motor directly transmits driving force to the driving wheels through the wheel-side speed reducer, the structure is simple and compact, and the transmission efficiency of the whole tractor is improved. In addition, different from traditional rear axle differential transfer, double-motor driving is adopted, torque distribution of the motors has a larger space, and the adaptive capacity of the electric tractor under various extreme working conditions is improved.

Description

technical field [0001] The invention belongs to the technical field of electric tractors, and in particular relates to a control method of an electric tractor driven by wheels. Background technique [0002] Traditional tractors are prone to lateral deviation when working in the field, that is, the wheels are attached to one side. Usually, the slip rate is too high, and the power of the tractor is poor. Even if some tractors are equipped with limited-slip differentials, electronic clutches and other components, it can achieve Torque and power adjustment, but still can not reach the full range, and the adjustment process will consume a lot of extra energy. At present, the chassis of agricultural electric tractors mostly use centralized drive or dual-motor coupling drive schemes, and the application of wheel-side drive configurations is very limited. [0003] As one of the unique distributed drive structures of electric tractors, the wheel-side drive power configuration adopts...
