Floating stator motor and hybrid drive system and hybrid tractor

Abstract

The invention relates to a floating stator motor, a hybrid power driving system and a hybrid power tractor. The floating stator motor comprises a motor shell, wherein an inner rotor and an outer rotor of which rotating axes extend along a front-back direction are rotationally arranged on the motor shell; a locking device is arranged between the outer rotor and the motor shell and is provided with a fixed end which is fixedly connected with the motor shell and a moving end which is capable of radially expanding and contracting towards the outer rotor; the moving end is provided with a locking position which is matched with the outer rotor in a blocking manner so as to enable the outer rotor and the motor shell to be relatively fixed, and an unlocking position which leaves the outer rotor so as to enable the outer rotor and the motor shell to relatively rotate; and a power output end of the floating stator motor is arranged on the inner rotor, and power input ends of the floating stator motor are arranged on the inner rotor and the outer rotor. The invention provides the floating stator motor which can realize two power coupling modes, namely torque coupling and rotating speed coupling, and meanwhile provides the hybrid power driving system and the hybrid power tractor which can output high torque and high rotating speeds.

Description

technical field [0001] The invention relates to the technical field of hybrid power, in particular to a floating stator motor, a hybrid tractor and a hybrid drive system using the motor. Background technique [0002] With the rapid development of science and technology, problems such as energy depletion and environmental pollution have become more and more prominent. For the tractor, its main function is reflected in: in agriculture, it is used for field cultivation, pulling and driving farm tools for farming; in industry and life, it is used for pulling and transporting heavy equipment. At present, traditional tractors mostly use diesel engines as power sources, which not only emit bad emissions and consume oil resources, but also require complex power conversion devices due to their high traction requirements, especially to meet the multi-speed gearbox structure under high-power traction. It greatly increases the research and development cost of the tractor and the diffic...

Problems solved by technology

However, the problem with the existing hybrid power system is that the ISG motor can only be coupled with the torque of the engine power unit, but cannot perform other coupling modes, and cannot be used in loaded engineering vehicles such as tractors and drilling rigs.
