The drive system adopting in the market has conventionally:
1. traditional approach, hybrid vehicle is direct motor of serial or parallel connection on former combustion engine, motor is directly connected with drive system by power-transfer clutch, adopt the closure of electronic control system control clutch to control with unlatching the through and off that motor power transmits, the method makes originally complicated driving system become more complicated, cause the miniaturization of the oversize restricting vehicle of driving system, share driving system with traditional combustion engine, make the speed torque characteristic of motor fail to give full play of, reduced the tractive performance of automobile.
2. adopt hub reduction tank shell and suspension swing arm and the wheel motor housing structure that is admittedly integrated mutually, this structure by elastic hinge joint in vehicle frame, be arranged on the semiaxis that connects wheel, engine output torque is at the synthetic wheel that outputs to of this and motor torque, this structural electromotor is arranged on the place that links of vehicle frame and suspension, excessive motor decelerating mechanism is installed complicated, and easy and suspension produces movement interference and is not suitable for pure electric automobile.
3. transmission device and the motor power assembly that connected to form by motor and gear reduction, be fixed on vehicle frame, motor torque connects gear reduction deceleration by torsional vibration damper and passes on wheel again, the method is that the diff in traditional vehicle bridge is removed with two motors and replaced, but output axle shaft and universal joint mechanism have still been retained, transmission device too much causes complex structure, and driving efficiency is low.
4. In-wheel motor driving, motor and wheel are made with integral body or directly motor be arranged in wheel, such structure suspension is arranged on stator, rotor direct drive of wheel, the torque characteristics of motor is, rotating speed high torque (HT) is low, and direct drive of wheel makes the speed torque characteristic of motor fail to give full play to, and motor easily damages for a long time in top load slow speed of revolution situation.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of low cost of manufacture, system dimension is little, handling is excellent wheel limit drive system, better to solve the contradiction of the flexibility transmission of electric car electric energy between transmitting with the energy rigidity of orthodox car.
The technical scheme of technical solution problem of the present invention is as follows:
A limit drive system, is characterized in that, comprises the motor module, slowdown module and the transfer panel that are mutually connected in series; Described slowdown module is NGW type satellite gear speed reduction gearing, and it comprises external toothing speed reducer housing, sun wheel, satellite gear, pinion carrier and retarder lid; Motor module is fixedly connected with external toothing speed reducer housing, motor output shaft adopts key to be connected with sun wheel, satellite gear is installed in pinion carrier, sun wheel, satellite gear, external toothing speed reducer housing are intermeshing, described planet carrier output shaft and transfer panel spline joint, the whole limit drive system of taking turns is fixedly connected on automotive hub by transfer panel.
From above disclosed technical scheme, the present invention is by adopting motor module to be installed in series into an integral body with slowdown module, utilize NGW satellite gear speed reduction gearing to slow down, there is the advantages such as transmitting ratio is large, axial dimension is short, load-carrying capacity is strong, stable, motor direct-drive sun wheel, after satellite gear slows down by pinion carrier transfer panel by power transmission to wheel.Its beneficial effect is as follows: arrangement is flexible, before and after can arranging respectively according to the driving of vehicle, drives or 4 wheel drive, can utilize space to increase; Driving efficiency improves, and power control becomes and flexibly connects by being rigidly connected, and by electron steering, 4 wheels independently are controlled, and more easily realizes 4 and takes turns and turn to and pivot stud, raising driving performance; By planetary gear reducing mechanism, slow down to increase and turn round, make full use of the torque characteristics of motor, wheel limit drives and adopts motor is propulsion source, conveniently carries out braking energy recovery, improves the dynamic property economy of automobile.
