Example Embodiment

[0019] Example: Combining figure 1 As shown, the roller brake motor device provided by the present invention has a main shaft 1 like the conventional technology. The main shaft 1 is equipped with a hub shell 2 through a bearing (not shown in the figure), and a hub end is fixed on one side of the hub shell 2 Cover 3, and the hub shell 2 is provided with a stator 4, a rotor 5, a planetary gear reduction mechanism and a clutch 7. The stator 4 is fixed on the stator support 6, the stator support 6 is fixed on the main shaft 1, and the gear box cover 8 is fixed on the stator support 6.

[0020] Specific as figure 1 As shown, the stator 4 and the rotor 5 in this embodiment adopt an outer stator and inner rotor structure. The planetary gear reduction mechanism consists of a central shaft 9 fixed to the rotor 5, a central shaft gear 10 arranged on the central shaft 9, and the central shaft The three planetary gears 11 (only one visible in the figure) meshed by the gear 10 and the plan...

Abstract

The invention discloses a roller brake motor device, which comprises a main shaft, a hub shell, a hub end cover, a stator, a rotor, a planetary gear speed reducing mechanism and a clutch, wherein the hub shell is arranged on the main shaft; the hub end cover is fixed on one side of the hub shell; and the stator, the rotor, the planetary gear speed reducing mechanism and the clutch are arranged in the hub shell; and the stator is fixed on the main shaft through a stator bracket on which a gear box cover is fixed. The roller brake motor device is characterized in that the clutch is a wedge type one-way clutch, and comprises an outer circle and an inner circle, the outer circle and the hub end cover are fixed, and an inner gear ring is fixed on the inner circle; and the planetary gear speed reducing mechanism comprises a center shaft fixed together with the rotor, a center shaft gear arranged on the center shaft, and a planetary gear fixed on the gear box cover through a planetary shaft, and the planetary gear is meshed with the center shaft gear and the inner gear ring at the same time. The roller brake motor device is compact in structure, convenient to assemble and high in operation stability.

Description

Technical field [0001] The invention involves a Roga motor device. Background technique [0002] The Roga Motor Device is mainly used by a wheel motor device that is supported by the Roga Motors, which can effectively meet the assembly needs of Roga brackets for electric bicycles. At present, it has been widely used on electric bicycles, especially in the European marketLarge demand (currently one -third of the electric bicycles in the Netherlands use Roga brake parts). [0003] At present, the composition of the Roga motor device mainly includes the spindle, the hub shell installed on the main axis, the hub -end cover fixed on the side of the hub shell, and the stator and rotor set in the hub shell.The inner gear on the hub shell is transmitted. At the same time, the planetary gear deceleration mechanism is also matched with the clutch to ensure that the motor device can achieve the purpose of "improving the safety of brakes and reducing the resistance of the taxi." [0004] The...
