The specific embodiment

The utility model is further described below with reference to embodiment (accompanying drawing):

Embodiment described in the utility model is provided with four drive motor 1, four drive wheels 5, four two yokes to hang assembly 3, four planetary reduction gears 4, four angle transmission mechanisms 6 and generator set or lithium celies 2 on the car body chassis.The arrangement of four drive motor 1 on the chassis has preposition or rearmounted two kinds: as shown in Figure 1, during preposition layout, two drive motor in car load front 1 adopt longitudinal (promptly with the equidirectional placement of generator set), by angle transmission mechanism 6 commutations; Two motors in car load rear portion adopt pressure-bearing type, with the posterior axis coaxial direction.As shown in Figure 2, during rearmounted the layout, two drive motor in car load front adopt pressure-bearing type, and two motors in car load rear portion adopt longitudinal (promptly with the equidirectional placement of generator set), by angle transmission mechanism 6 commutations.As shown in Figure 3, be provided with planetary reduction gear 4 and drg 9 in the wheel rim 8 of each drive wheel 5 tire 7, the braking principle of drg 9 is identical with conventional butterfly braking.The ways of deceleration that planetary reduction gear 4 adopts is the sun wheel input, and external toothing is fixed, pinion carrier output.The external toothing of planetary reduction gear 4, is connected with bolt or for integral type with track arm apart from the chassis is inner with wheel rim 8 usefulness bolt or for integral type is connected apart from the outer end, chassis.Each drive wheel 5 all the two yokes by separately to hang assemblies 3 fixing with chassis 1, the end that promptly two yokes hang assemblies 3 and drive wheel 5 by bulb be connected, the other end is connected with The One On The Chassis vehicle frame.The input end of each planetary reduction gear 4 all angle transmission mechanism 6 (or constant-velocity universal joint) by separately is connected with the mouth of drive motor 1 separately.The car load propulsion source adopts the generator set generating to each drive motor power supply, or by the high-energy-density lithium battery power supply, generator set and lithium cell can be provided with simultaneously.

What four drive motor 1 adopted all is efficient rare-earth brushless, permanently synchronous dynamos, is inner rotor core.As shown in Figure 4, each drive motor is formed by front bearing cap 10, front bearing 11, front end cover 12, p-m rotor 13, stator 14 and rear bearing 15, rear side housing 16, rear bearing cover 17, p-m rotor 13 is the built-in structure of permanent magnet, be " V " type shape, mechanical strength is higher, be fit to high-speed operation, have higher specific power, be easy to realize weak magnetism speed expansion.Permanent magnet rare-earth Nd-Fe-B material, anti-irreversible demagnetization ability is strong, is not easy loss of excitation.Employing is carried out every magnetic every magnetic bridge, and is simple in structure, reliable.By inverter supply, photoelectric encoder is housed on rotor, constitute the rotor-position closed loop control system, can realize High Accuracy Control and high reliability, wide range input voltage makes the speed adjustable range of drive motor wider.Employing reduces measures such as stator 14 trough aperture dimension, skewed stator slot and reduces stray loss, reduces location torque, increases low-speed stability.Stator 14 and p-m rotor 13 are sealed on the axle by front bearing cap 10, front bearing 11, front end cover 12 and rear bearing 15, rear side housing 16, rear bearing cover 17, between axle front bearing 11 on one side and front bearing cap 10, on one side rear bearing 15 and rear bearing cover 17 all adopts labyrinth seal in addition; Other local O shape rubber seal and liquid sealant of adopting seals, and degree of protection is IP57.Dipping lacquer adopts the H class B insulation lacquer of high adhesion force, outlet epoxy resin embedding, and structure design is firm, has vibration resistance.Whole motor is a hermetically-sealed construction, and can bear immersion and unlikely motor is caused deleterious effect.That this drive motor has is simple in structure, reliable, volume is little, light weight, little, the efficient advantages of higher of loss.Do not need idle exciting current, power factor improves greatly, and has reduced stator current and loss, and rotor does not have iron loss, no aluminium consumption, so efficient improves greatly.In 25%～120% rated load, nominal load scope, all can guarantee higher efficient and higher power factor; Efficient and power factor are all greater than 0.95 during rated load, nominal load, and energy-saving effect is more remarkable.

" difference power differential " problem of wheel is controlled it by the controller that is provided with inside and outside during for the turning that occurs in travelling, realizes down permanent torque control of base speed and down weak at a high speed magnetic control system, the reliability height.What control circuit adopted is conventional control circuit.
