Abstract
The utility model relates to a motor wheel set unit flexibly supported on a motor and provided with gearless drive. The conventional motor wheel set unit adopts gear drive for transmitting force moment, so that the contradiction between the high rotating speed and small torque of the motor and the low rotating speed and large torque of the wheel set can be overcome, however with an additional gear drive system. According to the novel motor wheel set unit, the center line of the motor coincides with the center line of an axle; a motor enclosure services as a motor stator, and is supported on a motor rotor via bearings; the motor rotor is supported on a hollow axle via elastic joints; electromagnetic torque produced by the motor directly drives the hollow axle via one of the elastic joints in a gearless drive manner; the hollow axle drives the axle via another elastic joint; counter torque produced by the motor enclosure is balanced by a motor pull rod on the motor enclosure; and rubber joints at the two ends of the motor pull rod are connected with the motor enclosure and a frame beam respectively. The motor wheel set unit can realize functions of the conventional motor wheel set unit, improves curve negotiating and high-speed running performances of a motor car, and has the characteristics of safety and reliability in structure and high transmission efficiency.
Description
Affiliated technical field
The utility model relates to the motor wheel of a kind of motor resilient mounting and gearless driving to the unit.
Background technology
Wheel is one of indispensable most important parts of motor car bogie to electric motor units, and the moment drive wheel that motor produces is to axletree, and this is the source that motor-car produces traction power; Because it need satisfy different requirements, thereby has been born various versions.At present, be subjected to the restriction of structure space and the weight of motor own, motor speed is higher, and the moment of generation is less, and wheel is lower to rotating speed, needs bigger drive torque, and this contradiction is solved by gear train assembly; Gearbox pinion links to each other with motor output shaft, and big gear wheel is installed in wheel on the axletree, and the little moment of torsion that motor produces amplifies the back to moment of torsion through the reducing gear train system, and directly drive wheel is right; Owing to increased a gear train assembly, infrastructure cost and life-cycle maintenance intervals cost are increased, reduce driving efficiency, increased noise, wheel-base bogie is strengthened, influence the curving performance of motor-car.Also has a kind of way simple in structure, motor case passes through the direct rigid support of bearing on axletree, axletree is exactly rotor, motor case is motor stator, the electromagnetic torque that motor produces directly drives axletree, the gearless driving system, simple in structure, the efficient height, noise is little, easy to maintenance, but the motor case rigid support is on axletree, and rail is to taking turns right various excitations and impacting all to have no to decay and directly pass to motor, and motor quality is bigger, thereby the action between the increasing wheel track firmly, worsen the performance of motor-car high-speed cruising, but little to the influence of motor-car low cruise, be suitable for low cruise.
Summary of the invention
In order to play the tradition wheel to the effect of electric motor units, reduce bogie structure cost and life-cycle maintenance intervals cost again, improve driving efficiency, reduce noise and wheel-base bogie, improve the curving performance of motor-car, especially will promote motor-car high-speed cruising performance, the utility model patent provides the new structure unit of a kind of reliable in structure, operation and application safety.
The utility model patent solves the technical scheme that its technical matters adopts: 1. motor center line and wheel are to central lines, and rotor is supported on the tubular axle by elastic joint, and motor case is exactly motor stator; 2. motor stator directly is supported on the rotor by bearing; 3. gearless driving, the electromagnetic torque that motor produces drives tubular axle by elastic joint, and tubular axle passes through the elastic joint drive wheel again to axletree; 4. motor stator and rotor all are supported on wheel on the axletree by elastic joint; 5. the counter torque of motor case generation is come balance by the motor pull bar on the casing, and the rubber arthrosis at motor pull bar two ends links to each other with truck transom with motor case respectively.
The beneficial effect of the utility model patent is: 1, reduced bogie structure cost and life-cycle maintenance intervals cost; 2, easy to use: this structural safety, reliable; 3, improve driving efficiency, reduced noise; 4, can reduce wheel-base bogie, improve curving performance; 5, promote motor-car high-speed cruising performance, reduced the wheel track action firmly.
Description of drawings
Accompanying drawing is the generalized section of the utility model patent.
In the accompanying drawing: 1. it is right to take turns, and 2. connecting bar disk one, and 3. elastic joint one, and 4. connecting bar disk two, 5. rotor, and 6. motor stator, 7. elastic joint two, and 8. connecting bar disk three, and 9. bearing one, 10. tubular axle, 11. bearings, two, 12. connecting bar disks four.
The specific embodiment
As shown in drawings, structure has efficient height, safety, reliable, the low characteristics of life-cycle maintenance intervals cost.
The specific embodiment is: the motor center line is overlapped 1 axle centerline with wheel, and motor case is exactly motor stator 6, motor stator by the direct rigid support of bearing bearing one, two (being piece number 9,11) on rotor 5; Gearless driving, the electromagnetic torque that rotor produces drives tubular axle 10 by elastic joint two (piece number 7), and elastic joint two links to each other with the connecting bar disk three (piece number 8) of rotor axle head and the connecting bar disk four (piece number 12) of tubular axle end respectively; Tubular axle 10 again by elastic joint one (piece number 3) drive wheel to axletree, elastic joint one links to each other with connecting bar disk one (piece number 2) on the axletree with the connecting bar disk two (piece number 4) of the rotor axis of electric other end respectively; The counter torque that motor case produces is come balance by the motor pull bar on the casing, and the rubber arthrosis at motor pull bar two ends links to each other with truck transom with motor case respectively.
Claims (1)
1. the motor of a motor resilient mounting and gearless driving wheel is to the unit, it is characterized in that: adopt this motor wheel to unit structural form, motor stator and rotor are supported on the right tubular axle of wheel by elastic joint, the electromagnetic torque that motor produces drives tubular axle by elastic joint, tubular axle again the elastic joint drive wheel by opposite side to axletree, the gearless driving system; The counter torque that motor stator produces is come balance by the motor pull bar on the casing, and the rubber arthrosis at motor pull bar two ends links to each other with truck transom with motor case respectively.
