The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail.
Referring to Fig. 1～Fig. 5, the utility model embodiment comprises wheel hub motor output shaft 1, attaching parts 2, catch gear, anti-return nut 6, and catch gear comprises latch segment 3 and locking bed 4.Wheel hub motor output shaft 1 is arranged on the wheel hub motor 15 of self-balancing wheelbarrow.
The end of wheel hub motor output shaft 1 has up and down for fixing upper plane 5 and lower plane 11.
On attaching parts 2, have mounting groove 7.Locking bed 4 is arranged in mounting groove 7, and locking bed 4 outsides are provided with the attaching parts locking face 14 of catch gear, and attaching parts locking face 14 makes catch gear circumferentially fixing with the wall close contact of mounting groove 7 with limiting locking mechanism.The wall of mounting groove 7 is inclined-plane, matches, and attaching parts locking face 14 is inclined-plane, and locking effect is good like this.
On locking bed 4, have locking hole 8 and upper locking inclined-plane 9.The end of wheel hub motor output shaft 1 installs and is fixed in locking hole 8, and the hole shape of locking hole 8 coordinates with the end profiles of wheel hub motor output shaft 1, is provided with lower output shaft locking face 10 in locking hole 8, and lower output shaft locking face 10 contacts with lower plane 11.
Latch segment 3 is between attaching parts 2 and locking bed 4, specifically between the bottom land and locking bed 4 of mounting groove 7.Latch segment 3 has lower locking inclined-plane 12 and upper output shaft locking face 13, lower locking inclined-plane 12 contacts and makes latch segment 3 have downtrend with upper locking inclined-plane 9, upper output shaft locking face 13 contacts with upper plane 5, and latch segment 3 and locking bed 4 by upper output shaft locking face 13 and lower output shaft locking face 10, push down upper plane 5 respectively and lower plane 11 is fixed on attaching parts 2 wheel hub motor output shaft 1.
Anti-return nut 6 is connected with the end of wheel hub motor output shaft 1 and is fixed inward locking bed 4 makes catch gear axial restraint, can adopt nut body to be provided with the nut of retaining or the profile by nut coordinates formation with attaching parts 2 or latch segment 3, while making motor positive and inverse, nut can not exit wheel hub motor output shaft 1.
Twist inward anti-return nut 6, anti-return nut 6 compresses locking bed 4 inward, locking bed 4 pushes latch segment 3 inward, by lower locking inclined-plane 12 and 9 effects of upper locking inclined-plane, latch segment 3 and locking bed 4 by upper output shaft locking face 13 and lower output shaft locking face 10, push down upper plane 5 respectively and lower plane 11 is fixed on attaching parts 2 wheel hub motor output shaft 1, and produces the more tighter effect of lock.
The material hardness of locking bed 4 and latch segment 3 is higher than the hardness of attaching parts 2 and lower than the hardness of wheel hub motor output shaft 1.The area of attaching parts locking face 14 is greater than the area sum of output shaft locking face 10 and lower output shaft locking face 13.So all make wheel hub motor output shaft 1 and attaching parts 2 form not consumable accessory.
Latch segment 3 is changeable types, in the poorest loss situation, also can keep in repair car body by the latch segment 3 of changing.
Although the utility model with embodiment openly as above; but it is not in order to limit protection domain of the present utility model; any technical personnel of being familiar with this technology, the change of doing within not departing from design of the present utility model and scope and retouching, all should belong to protection domain of the present utility model.
