Summary of the invention
Problem to be solved in the utility model is to provide a kind of excessive hybrid drive with not realizing the problems such as the independent driving of driving engine of motor volume in existing combined hybrid system that solves.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of novel automobile hybrid drive, comprises driving engine, the first motor, the first axle, synchro sliding hub mechanism, the second motor, planet arrangement mechanism and the second axle;
The first motor is engine starting and power generation all-in-one machine, and its rotor shaft one end is connected with engine crankshaft, and the other end is connected with the first axle;
Synchro sliding hub mechanism comprises that fixed engagement gear ring, feather key hub, sliding hub and the second rotor engage gear ring, fixed engagement gear ring is fixed on the first electric machine casing, feather key hub is connected with the first axle, sliding hub is with feather key hub sliding block joint, and the second rotor engages gear ring and is connected on the rotor shaft of the second motor;
The rotor shaft of the second motor is hollow shaft, and described the first axle is through the rotor shaft of described the second motor;
Planet arrangement mechanism is single planetary row structure, comprises from inside to outside sun wheel, satellite gear and the gear ring of engagement successively, also comprises the pinion carrier that supports satellite gear; Sun wheel connects with the first axle, and pinion carrier connects with the second axle as power take-off shaft, and gear ring connects with the second rotor axis of electric.
The method of work of this device is:
Under pure motorized motions mode, sliding hub is with the combination of fixed engagement gear ring, and driving engine is not worked, the first motor is not worked, the first axle is fixed, and the second motor is worked in electrical motor mode, and the power of the second motor is exported by the second axle axle after planet arrangement mechanism slows down;
Under hybrid power type of drive, feather key hub is in unbound state, engine operation, and the first motor is worked in electrical generator mode, and the second motor is worked in electrical motor mode, and engine power and the second motor power are exported by the second axle after planet arrangement mechanism coupling;
Under the independent type of drive of driving engine, engine operation, sliding hub engages gear ring combination with the second rotor, the second motor is not worked, now between the each parts of planet arrangement mechanism, there is no relative motion, be equivalent to engine power directly by the first axle, more directly exported by the second axle through planet row;
Under feedback braking mode, the second motor is worked in electrical generator mode, reclaims vehicle braking kinetic-energy.
Advantage and the good effect that the utlity model has are: adopt a planet arrangement mechanism to coordinate synchro sliding hub mechanism, realize that pure motorized motions, hybrid power drive, driving engine drives separately and four kinds of mode of operation of regenerative braking, thereby effectively reduce energy consumption, simple in structure, cost.
