, adjustment steel disc, axle sleeve, axle sleeve is relative vehicle body, the material that more matter is hard is prepared from, by the mode of die casting vehicle body die casting on axle sleeve, axle sleeve is connected with vehicle body formula, and axle is arranged in axle sleeve, because axle sleeve is that hard material is formed, the power can not born with axle and produce deformation, for making axle more firmly be connected with vehicle body, shaft tail end passes throughcrescent moon part
, adjustment steel disc and flange nut be fixed on further on vehicle body.
a kind of Double-wheel self-balancing Electricmotor car wheel described in the utility model and vehicle body fixed connection structure, in the fixed parts of anchor shaft and vehicle body, crescent moon part is as the buffering between axle sleeve and flange nut, effectively improves the fastening dynamics of flange nut.The general choice for use rigid material of flange nut, preferably through the process of quenching stiffened.
a kind of Double-wheel self-balancing Electricmotor car wheel described in the utility model and vehicle body fixed connection structure, in the fixed parts of anchor shaft and vehicle body, crescent moon part is two, crescent moon part depressed area to being buckled on axle, and is arranged between flange nut and axle sleeve, is lined with adjustment steel disc between crescent moon part and vehicle body.On the one hand rough because of bodywork surface, adopt steel disc, steel disc can be utilized as medium, reduce friction force between crescent moon part and vehicle body, the effect of lubrication part got by steel disc, be convenient to flange nut screw in, reduce gap according to the steel disc of the Interval selecting suitable depth between crescent moon part and vehicle body on the other hand, improve overall tightness with this.
crescent moon part depressed area opposite in axletree in a kind of Double-wheel self-balancing Electricmotor car wheel described in the utility model and vehicle body fixed connection structure and the fixed parts of vehicle body is inclined-plane, nearly wheel place tilts to axle, the face of the screw hole on corresponding vehicle body is also a dip plane, flange nut heads on crescent moon part and makes toward nearly wheel place screw-in, face due to screw hole is inclined-plane, hole is more and more less, adjustment steel disc is padded between crescent moon part and vehicle body, corresponding vehicle body cover inclination corresponding with crescent moon part, nearly wheel place tilts to axle, so in continuous screw-in process between flange nut and crescent moon part, between crescent moon part and axle, between crescent moon part and adjustment steel disc, the Contact of adjustment steel disc and vehicle body is more and more tightr.
on flange nut in axletree in a kind of Double-wheel self-balancing Electricmotor car wheel described in the utility model and vehicle body fixed connection structure and the fixed parts of vehicle body axle below, adjacent flange nut place band is porose, fixed parts comprises spring cotter further, and spring cotter is arranged in the hole on axle.Spring cotter screws out for limiting flange nut.Add spring cotter further on axle, for fastening to flange nut, prevent flange nut from having loosening, can effectively stop flange nut outward turning.
axle sleeve in axletree in a kind of Double-wheel self-balancing Electricmotor car wheel described in the utility model and vehicle body fixed connection structure and the fixed parts of vehicle body, that vehicle body is fixed on axle sleeve by die casting, select axle sleeve that material is more harder than vehicle body as the medium between axle and vehicle body, improve the load-bearing dynamics of car body entirety.
axle sleeve in the anchor shaft of a kind of external motor type self-balancing two-wheeled electrocar described in the utility model and the fixed parts of vehicle body, axle sleeve is pressed in vehicle body by interference mode.
axle sleeve in axletree in a kind of Double-wheel self-balancing Electricmotor car wheel described in the utility model and vehicle body fixed connection structure and the fixed parts of vehicle body, be connected with vehicle body by the mode of die casting, vehicle body is fixed on axle sleeve by die casting, sleeve outer surface and body sticker splice grafting touch, the outside face of axle sleeve is coarse or be provided with depressed area on surface, effectively can improve the binding force between vehicle body, if by or depression treatment such die casting in its surface vehicle body in the horizontal direction between the two stripping coarse to boss surfaces, its peeling force needed is larger, what axle sleeve and vehicle body were fixed is more firm, effectively prevent axle sleeve and vehicle body from coming off.
axle sleeve in axletree in a kind of Double-wheel self-balancing Electricmotor car wheel described in the utility model and vehicle body fixed connection structure and the fixed parts of vehicle body, inner hole of shaft sleeve two ends diameter is not etc., the diameter of nearly road wheel end is greater than road wheel end far away, and the line on two ends and the angle between horizontal surface are preferably between 1 °-3 °.
