Power is exported by motor, be passed on the small pulley with its coaxial line, small pulley through synchronous cog belt with transmission of power to big belt wheel; Playing slows down increases the effect of turning round; Big belt wheel is affixed with semiaxis one end, and its other end of said semiaxis passes through spline and is connected with wheel hub, thus with transmission of power to wheel hub; And then driving and the affixed wheel rim of wheel hub, with drive wheels.Said motor center axis and small pulley central axes, said wheel center axis and big belt wheel and semiaxis central axes, said motor center parallel axes is in said wheel center axis.
Adopt Synchronous Belt Drives, can increase motor center axial location and wheel center axial location distance, thus make motor centroid position and simple pendulum arm center of suspension axis try one's best near, reduce equivalent nonspring carried mass.
Synchronous Belt Drives has and operates steadily noiseless, the advantage that transmitting ratio is constant.The efficient of Synchronous Belt Drives also is higher than gear transmission, and its transmission width between centers does not receive the restriction of belt wheel size yet.Synchronous Belt Drives need not grease lubrication, has saved lubricating system, has reduced the seal request of deceleration box, thereby has reduced the sole mass of wheel limit drive system, makes nonspring carried mass reduce.
The superior effect of the utility model:
1) adopts Synchronous Belt Drives, reduced the noise that driving system produces, improved the efficient of driving system; 2) save lubricating system, reduced the seal request of deceleration box, thereby reduced the nonspring carried mass of system;
3) ride comfort of lifting automobile, the ground connection property of wheel.
