The utility model solves the technical problems by adopting the technical scheme that: the utility model provides an electric handcart's in-wheel motor fast-assembling structure, is including being located a pair of output shaft of in-wheel motor left and right sides, still including being equipped with the supporting part of arranging in on the output shaft, the supporting part lower extreme is equipped with the spacing groove of going into the output shaft from the side card, and the inner department of spacing groove is equipped with the spacing subassembly that limits the output shaft in the spacing inslot.

Preferably, the support member is welded to the frame.

Preferably, one side of the hub motor is provided with a disc brake screw mounting hole, and the supporting part on the same side is provided with a disc brake screw mounting hole.

Preferably, the limiting assembly comprises a fixing piece fixed on the supporting component, and a through hole for the output shaft to pass through is formed in the fixing piece.

Preferably, the outer end of the output shaft is provided with threads and is provided with a nut in a threaded manner, and the nut is positioned on the outer side of the fixing piece.

Preferably, the fixing member is mounted on the support member by a screw.

Preferably, the cross section of the output shaft is rectangular, and the shape of the output shaft is matched with that of the limiting groove.

The beneficial effects of the utility model are as follows: when the hub motor is installed, the quick assembly structure is adopted, quick and convenient installation can be realized through the cooperation of the limiting groove and the limiting component, meanwhile, the distance between the disc brake sheet and the disc brake device can be finely adjusted, and the assembly problem caused by manufacturing dimensional errors caused by bent pipe and welding is effectively solved.

Detailed Description

The utility model is further described below with reference to the accompanying drawings:

referring to fig. 1, 2 and 3 and 4: the wheel hub motor fast-assembling structure of electric handcart in this embodiment, including being located wheel hub motor 1 left and right sides's a pair of output shaft 2, still including being equipped with the supporting part 3 of arranging on output shaft 2, be equipped with on the supporting part 3 about two fixed part 33 that are used for providing the supporting role to frame 9, open the one side that supporting part 3 was kept away from to fixed part 33 upper end has recess 34, the welding has welded plate 32 between the recess 34 about, supporting part 3 passes through welded plate 32 and welds on frame 9, the supporting part 3 lower extreme is equipped with spacing groove 4, output shaft 2 can go into spacing groove 4 from the side card, the inner department of spacing groove 4 is equipped with the spacing subassembly that is spacing output shaft 2 in spacing groove 4, spacing subassembly is including fixing the mounting 5 on supporting part 3, it is used for the mounting screw to fix mounting 5 on supporting part 3 to open on the mounting 5, the through-hole 52 that the output shaft 2 passed still has been opened at the mounting 5 center, the through-hole 52 diameter is slightly greater than the diameter of output shaft 2 for output shaft 2 can be in axial displacement, the outer end of output shaft 2 is equipped with the screw thread, the output shaft 2 outside, the output shaft 2 passes through the screw thread 6, the inner end department of spacing nut 6 is equipped with the nut 6, nut 6 is located the diameter of the nut 2 is fixed by the nut 2 in the diameter of the nut of the outside nut 2.

Specifically, six evenly distributed disc brake piece screw mounting holes 11 are formed in one side of the hub motor 1, the disc brake pieces 7 are mounted on the side through screws, two disc brake piece screw mounting holes 31 are formed in the supporting part 3 on the same side, and the disc brake pieces 8 are mounted on the supporting part 3 through screws.

Further, the cross section of the output shaft 2 is rectangular matched with the limit groove 4, so that the output shaft 2 can be conveniently clamped into the limit groove 4 to be limited.
