(2) background technology
Therefore advantages such as everyone knows, wheel limit type of drive is compared with the type of drive of hub-type motor with middle shaft type motor, has the reduction ratio height, and the high and dynam controllability of transmission usefulness is good, are paid attention to by industry always.But, because it is low that wheel limit type of drive exists center-of-gravity position, and the active flank that mutual rotation is arranged, existing electric machine structure is restricted in addition, therefore can't form mechanical seal and actv. power lubrication, when this vehicle that just makes travels, very easily cause fatal infringement to wheel limit drive system on muddy water and sandy soil road surface.So wheel limit type of drive is still showed on the notion vehicle mostly, also is not generalizable on vehicle design so far.
(3) summary of the invention
Technical assignment of the present invention is at the deficiencies in the prior art, provides a kind of and can effectively solve the centering type sealing wheel limit driving electric drive wheel that the wheel limit drives sealing problem.
The technical solution adopted for the present invention to solve the technical problems is:
Centering type sealing wheel limit drives electric drive wheel, comprise the external gear wheel hub motor, wheel nave, tire, tire is arranged on the wheel nave, thereby the bilateral symmetry of wheel nave is provided with left side end cap and right side end cap and surrounds an annular seal space that holds the external gear wheel hub motor, axis passes from the center of left side end cap and right side end cap and is fixed by bearing, the external gear wheel hub motor is fixed on the axis by electric machine support and the motor shaft of external gear wheel hub motor is positioned at a side of axis, and the inboard of above-mentioned wheel nave is provided with the internally toothed annulus that is meshed with the external gear of external gear wheel hub motor.
Above-mentioned centering type sealing wheel limit drives electric drive wheel, its axis is according to the diameter of external gear wheel hub motor, adopt the settings of axis setting or left and right sides two-semiaxle, when adopting left and right sides two-semiaxle to be provided with, in order to guarantee the installation fastness of external gear wheel hub motor, its electric machine support can adopt U type supporting structure.
Above-mentioned centering type sealing wheel limit drives electric drive wheel, for increasing the sealing property of annular seal space, prevent that impurity such as dust from entering the normal operation that annular seal space influences the external gear wheel hub motor, can between its left side end cap and axis, be provided with the left side seal ring, between its right side end cap and axis, be provided with the right side seal ring.
Aforementioned external teeth wheel wheel hub motor, comprise motor shaft and stator fixed thereon, stator is arranged with rotor case outward, left side rotor endcap, right side rotor endcap and bearing rotatable be fixed on motor shaft on of rotor case by being positioned at its left and right sides, external gear can be set on rotor case, also can between left side rotor endcap and right side rotor endcap, select one external gear is set, can also on left side rotor endcap and right side rotor endcap, external gear be set respectively.
Centering type sealing wheel of the present invention limit drives electric drive wheel, and its principle of work is as follows:
During the work of external gear wheel hub motor, the external gear that its rotor case drives on it rotates, and the internally toothed annulus that external gear drives again on the wheel nave rotates, thereby drives whole wheel nave and tyre rotation.
Centering type sealing wheel of the present invention limit drives electric drive wheel compared with prior art, and the beneficial effect that is produced is:
The present invention has realized that the wheel limit drives on vehicle design hermetically sealed to mutual rotation active flank, so eliminated the safety hazard when vehicle travels on muddy water and sandy soil road surface.And the active flank of mutual rotation can be turned round under lubricating status.
