Electric drive system of multi-wheel drive tracked vehicle and control method thereof

Abstract

The invention discloses an electric drive system of a multi-wheel drive tracked vehicle and a control method of the electric drive system, a hub electric drive device is arranged in a hub of a drivewheel to form an electric drive wheel, the electric drive wheel is arranged outside a vehicle body, and a large amount of space in the vehicle is saved; the electric driving system is provided with four same electric driving wheels, an optimization model is solved under the condition that the sum of power is minimum, the output torque of hub motors on the left side and the right side is obtained,it can be guaranteed that the output torque of the hub motors is reasonably distributed, the efficiency of the electric driving system is the highest, and energy utilization maximization of the electric driving system is achieved.

Description

technical field [0001] The invention belongs to the technical field of hybrid vehicles, and in particular relates to an electric drive system of a multi-wheel drive crawler vehicle and a control method thereof. Background technique [0002] In order to achieve optimal power matching, improve transmission efficiency, maximize energy utilization, and improve vehicle battlefield survivability, the drive scheme of multi-wheel drive tracked vehicles has been studied by many scholars. There are two main schemes for the current drive system: one is to replace the induction wheel with a driving wheel, and one motor drives one driving wheel to realize four-wheel drive. The motor is arranged in the car body, but it takes up too much space in the car body; the other is It is to install the motor in the road wheel, turn it into a power output point, and then drive the driving wheels on both sides respectively by two motors installed in the car body to realize multi-wheel drive, but the ...

There are two main solutions for the current drive system: one is to replace the induction wheel with a driving wheel, and one motor drives one driving wheel to realize four-wheel drive. The motor is arranged in the car body, but it takes up too much space in the car body; the other is It is to install the motor in the road wheel, turn it into a power output point, and then drive the driving wheels on both sides by two motors installed in the car body to realize multi-wheel drive, but the electric road wheel relies on the friction between the track and the track. Power transmission, large loss, complex control, low energy utilization
