Embodiment 1

[0029] Such as figure 1 As shown in , the sliding gear variable speed electric hub includes a hub ring 1, the hub ring 1 is connected with an end face 2, the end face 2 is connected with the hollow output shaft 5, and a shaft hole 15 of the hollow output shaft 5 is provided with a Root integral solid supporting shaft 20. An integral solid support shaft 20 is not only convenient for manufacturing and processing, but also convenient for assembly. Compared with the hollow support shaft provided with a power line hole, it has good rigidity and supporting strength.

[0030] The motor 3 is fixed on the support shaft 20, and the power cord 59 of the motor 3 directly stretches out from the casing of the motor. The motor 3 is fixed on the support shaft 20, and the motor shaft gear 47 is arranged on the outer end of the motor shaft 46. The motor 3 is fixed with a gearbox body 21, and the gearbox body 21 can be fixed on the shell of the motor 3, or can be made into an integral structur...

Embodiment 2

[0037] The axial end of the retainer 13 is in contact with a clip 66, and the adjustment rod 30 is connected to the clip 66. The other end of the adjustment rod 30 is provided with a screw 4, and the screw 4 is connected to the threaded hole 26 on the internally threaded gear 24. Cooperate, when the stepper motor 31 fixed on the support shaft 20 rotates, it drives the inner screw gear 24 to rotate, and when the inner screw gear 24 rotates, the adjustment rod 30 is pushed or pulled to move in the shaft hole 15, and the stopper 13 is driven to move in the shaft hole 15. middle movement, the other end of the stopper 13 is provided with a return spring 68 that can return it to its position and snap into the inner groove 11. The return spring 68 is sleeved on the support shaft 20. When the adjustment rod 30 moves outward, the return spring 68 will push the stopper 13 is pushed back in the internal groove 11 of the driven gear 9 of low gear, this moment is first gear.

[0038] Descr...

Embodiment 3

[0042] Such as image 3 Shown in, it is different from embodiment 1,2 except that: stepper motor 31 or lever bracket 41 are not established on the fulcrum 20, and electromagnetic suction 39 is established.

[0043] In the initial state, such as image 3 , Figure 5 As shown in , the stopper 13, the adjustment rod 30 and the suction plate 40 are pushed outward under the action of the elastic force of the return spring 68 on the support shaft 20, at this time the stopper 13 leaves the annular neutral gear 28 and blocks the slave of the low gear. In the driven gear inner groove 11, the stopper 13 is combined with the driven gear 9 hollow output shaft 5 of the low gear to rotate. The driven gear 9 of the low gear drives the hollow output shaft 5 to rotate, and the hollow output shaft 5 connects the end face 2 and the hub ring 1 to rotate around the fulcrum 20, which is now the first gear.

[0044] When the electromagnetic suction 39 is energized, the electromagnetic suction 39 ...

Abstract

The invention belongs to the technical field of wheels, and discloses an electric shifting wheel hub with a sliding stopper, which is used for solving the problem of easiness in breaking a support shaft and influence on the driving safety due to reduction in the strength of the support shaft caused by the formation of a power wire hole on an original support shaft and the problem of failure in effectively dissipating heat of a motor wrapped inside a hub ring. The electric shifting wheel hub with the sliding stopper comprises a hub ring, an end face, a support shaft hole, a support shaft and a motor, wherein an adjusting rod is connected with the stopper; the stopper arranged in a shaft hole of a hollow output shaft can be moved by rotating a stepper motor shaft; during movement, the stopper can be clamped in an inner groove and connected with a driven gear and can rotate together with the hollow output shaft; the hollow output shaft and an input shaft are arranged in a transmission case; the support shaft is inserted into the shaft hole of the hollow output shaft; the input shaft is in transmission connection with the motor shaft; the hollow output shaft is in transmission connection with the hub ring; the hollow output shaft is provided with a stopper moving groove and at least two rotatable driven gears; a driving gear is correspondingly fixed on the input shaft; an inner groove is formed on the shaft hole wall of the driven gear; the support shaft is provided with the stopper; and the stopper can be clamped into the inner groove.

Description

technical field [0001] The invention belongs to the technical field of wheels. Background technique [0002] The notification number CN201501246 discloses a sliding gear variable speed hub, which mainly includes a hub ring, a motor and a gearbox body are wrapped inside the hub ring, and a hollow support shaft protruding from the two end faces of the hub ring is fixed on the motor. Has a power cord hole. The hollow fulcrum of the wheel hub of this structure increases the difficulty of processing and assembly because of the power cord hole, and also greatly weakens the rigidity and strength of the fulcrum. During use, the fulcrum will be easily deformed and broken, which will threaten the safety of driving. In addition, because the motor is wrapped by the hub ring, the heat emitted by the motor during operation cannot be effectively dissipated and cooled, and the motor and components will be easily burned due to overheating. Contents of the invention [0003] In order to s...
