Abstract
The invention relates to a double-motor direct drive rear axle, which is combined by two half bridges which have the same structure and are symmetrical. Each half bridge comprises a stator, an external rotor, magnetic steel, a stator fixed sleeve, an external rotor fixed sleeve, a bearing, a spline half axle and a bridge housing part. The structure is characterized in that, in each half bridge, the stator, the stator fixed sleeve and the bridge housing are connected into a whole through the flange plate of the stator fixed sleeve; the bearing is closely matched and connected with the stator fixed sleeve and the external rotor fixed sleeve respectively, a spline slot is arranged in the external rotor fixed sleeve and connected with the spline half axle in moving fit, and the flange plate at the other end of the spline half axle is connected with a rear wheel; the flange plate at one end of the external rotor fixed sleeve is fixedly connected with the external rotor through a bolt; and the magnetic steel is permanently fixed in an inner circle of the external rotor. The working principle is as follows: under the drive of a motor speed governor, coils in stator wire slots generate a rotating magnetic field, the magnetic steel is used for driving the external rotors to rotate under the action of the rotating magnetic field and the spline slots in the external rotor fixed sleeves are used for transferring power to the spline half axles for driving the rear wheels to rotate.
Description
Technical field
The present invention relates to electric capacity battery-driven car and double cell hybrid electric vehicle with rear-axle drive.
Background technology
At present, the battery-driven car of all rear-axle drives, electrical motor is earlier by driving trailing wheel again behind mechanical reduction, the mechanical differential.This type of drive is not only brought into play the speciality of DC motor low speed starting ability free from worldly cares and super capacitor transient large current discharge, also makes complicated in mechanical structure, and transmission efficiency descends.
Summary of the invention
The technical solution adopted for the present invention to solve the technical problems is: a kind of double-motor directly drives back axle and is combined by the identical symmetrical half-bridge again of two structures.Its half-bridge by: stator, outer rotor, magnet steel, stator fixed cover, outer rotor fixed cover, bearing, spline semiaxis, axle housing body component are formed.Its part architectural feature is: coil is arranged in the stator slot, and nonvolatil being fixed on the stator fixed cover cylindrical of circle in the stator, both are integral; Circle has the anti-bearing of seam only to run out of in the interior circle of stator fixed cover and the outer ring flush fit of two bearings, one end, and the other end has flange, and flange is fixed by bolts on the axle housing body, and with stator, stator fixed cover, axle housing sports association is integral; The cylindrical flush fit of the inner ring of two bearings and outer rotor fixed cover, the interior circle of outer rotor fixed cover has spline, the spline running-fit of spline and spline semiaxis one end, the flange of the spline semiaxis other end connects trailing wheel; The flange of outer rotor fixed cover one end is fixedly connected with bolt and outer rotor; Magnet steel is nonvolatil to be fixed in the interior circle of outer rotor.
Principle of work is: the stator slot interior loop of two half-bridge motors, and under governor driving separately, the stator cylindrical produces rotating field, and magnet steel drives outer rotor and becomes power under the effect of rotating field.Power passes to the spline semiaxis by the spline in the outer rotor fixed cover and drives the trailing wheel rotation.Work as Ackermann steer angle, under the control of vehicle-mounted computer, the rotating speed between two governors can change descends the speed of curved inside rear wheel, cooperates vehicle to turn smoothly.
Beneficial effect of the present invention:
The present invention directly drives trailing wheel with electrical motor, has taken leave of the history of motor gear's transmission, has realized battery-driven car no oiling truly, makes that the battery-driven car drive mechanism is easier, and transmission efficiency is higher, and maintenance cost is lower.
Description of drawings:
Fig. 1 is structural representation of the present invention.
The back axle structural representation that Fig. 2 combines for the present invention.
Among Fig. 1,1. stator, 2. outer rotor, 3. magnet steel, 4. stator fixed cover, 5. outer rotor fixed cover, 6. bearing, 7. spline semiaxis, 8. axle housing body.
The specific embodiment:
The big end of two symmetrical half bridges shown in Figure 1 has flange, with bolted two flanges, two half-bridges is combined into complete back axle.The back axle structural representation that Fig. 2 combines for the present invention.The motor of two half-bridges has governor separately to drive, the stator cylindrical produces rotating field, magnet steel drives outer rotor and becomes power under the effect of rotating field, power passes to the spline semiaxis by the spline in the outer rotor fixed cover and drives the trailing wheel rotation, work as Ackermann steer angle, under the control of vehicle-mounted computer, the rotating speed between two governors can change, the speed of curved inside rear wheel is descended, cooperate vehicle to turn smoothly.
