New description: [New technical field] „This creation is related to bearings, especially an early two-way bearing used for electric bicycle driving. [Prior Art] "The electric bicycle is driven by human pedaling and/or motor drive. Electric ordering driving 'In order to realize manpower and motor can drive independently and without affecting each other' usually adopts a clutch device, that is, a single bidirectional bearing is installed on the electric bicycle center shaft. Please refer to Figure b for the conventional single bidirectional wheel bearing. Schematic diagram of the structure. Vertical ratchet and pawl structure, the ratchet wheel 1 drives the bicycle to sense the door... The circle has a pawl seat, the motor drive plate 2 is set in the second motor and the outer ring of the motor drive plate 2 is provided with a pawl seat. , the spine water setting = the middle ratchet of the outer ring of the driving disc 2 drives the middle ratchet] one-way rotation, the bicycle sprocket 4 is connected to the outer wheel, and the inner ring of the ratchet wheel 3 is provided with ratchet teeth, as shown in Fig. 1 As a matter of course, when the outer ring is rotated from the & car sprocket 4 clockwise and the ratchet wheel 3 is rotated in the same direction, the ratchet of the outer ring ratchet 3 abuts the pawl of the intermediate ratchet 1 so that the intermediate ratchet is 'rrn wheel 1 Rotate clockwise, but drive the motor drive disc 2. If the electric motor drive disc 2 rotates clockwise, "undisclosed" is activated and turned Π 1 ^ 1 λ, ® , the pawl of the motor drive disc 2 and the intermediate ratchet 1 The ratchet of the inner ring rotates against the τ, but at this time the middle ratchet i is read - the clockwise π T ratchet 1 does not carry the bicycle-driven single bidirectional ^ 2 ring ratchet 3. Therefore, the stepping and/or the motor running b can be achieved by the manual stepping and the use of the ratchet and the pawl 3 M435525 to the bearing, so that the driving drive fails, and the claw hits the outer ring ratchet to carry a large amount of noise. Structure, when the motor starts, the pawl and the ratcheting force of the ratcheting force often break or break, resulting in the sound of the thorns, cymbals, and cymbals of the outer ratchet outer ring when the manpower is not stepping on. This single bidirectional shaft sounds the ride of the bicycle. [New content] The purpose of this creation is to solve the problem that the bicycle can not be driven due to the strong force of the motor and the breakage or breakage of the pawl. The single bidirectional bearing of the present invention overcomes the defects of the conventional ratchet and pawl driving bicycle. The structure is simple, the weight is light, the volume is small, the work can be #, the sound is not squeaked, and the bicycle driving efficiency is high. The present invention provides a single bidirectional bearing for electric bicycle driving, which comprises a motor driving disc, an intermediate driving disc, an outer driving # connected to the bicycle sprocket, a plurality of inner ring lugs which are curved at opposite ends and which are opposite to each other and a plurality of outer ring lugs having curved ends and protruding toward each other, wherein the motor driving disc, the intermediate driving disc and the outer driving disc are sequentially assembled, and the plurality of inner ring lugs are respectively disposed on the motor driving disc through the cage The plurality of outer ring bumps are disposed between the intermediate driving plate and the outer driving plate through the retainer, and the plurality of inner ring bumps are opposite to the plurality of outer ring bumps Arranging, when the motor drives the motor drive disc to rotate, the plurality of inner ring protrusions upright drive the intermediate drive disc to rotate, the plurality of outer ring protrusions are inclined, and the outer drive disc has no rotation, When the sprocket wheel drives the outer drive disc to rotate in the forward direction, the plurality of outer ring protrusions uprightly drives the intermediate drive disc to rotate. The plurality of inner ring bumps are tilted, and the motor drive plate M435525 '...rotes' bicycle The chain (4) moves outside (4) and the outer ring is tilted. When it is still, the intermediate drive disk of the plurality of halls has no rotation. Because the utility model is used for the single bidirectional shaft driven by the custom soap, the above technical solution is used. Immediately after the spoon bearing picking plate is set in turn, a plurality of inner gardening and auxiliary driving inner ring bumps are respectively arranged on the motor driving plate and the intermediate driving plate through the retaining frame < ' ^ ' a plurality of outer ring bumps The cage is disposed between the intermediate drive disc and the outer drive-like disc, and the plurality of inner ring bumps are arranged opposite to the outer ring bumps, and the lightning machine·the motor ▼ moves the motor drive disc to rotate, and the plurality of The inner ring protrusions drive the intermediate driving disc to rotate. When a plurality of outer ring lugs are tilted, the outer driving disc does not rotate, and when the bicycle sprocket drives the outer driving disc to rotate in the forward direction, a plurality of outer ring lugs rise up to drive the intermediate driving disc to rotate. Multiple The inner ring cam tilts the motor drive (4) without rotation. When the bicycle sprocket drives the outer drive plate to rotate in the opposite direction, the plurality of outer ring lugs are inclined, and the middle drive plate is not rotated. The single bidirectional bearing overcomes the traditional (four) ratchet and pawl The defect of driving the bicycle is simple in structure and light in weight. I* is connected to I-JL. The dry one is small in size, reliable in operation, free from noise, and has high efficiency in bicycle driving. [Embodiment] The following is applicable to the case. The embodiments of the single-bidirectional bearing driven by the electric bicycle are described as 'Please refer to the off, but the actual configuration and the method of the adopted method do not have to completely conform to the described contents, and it is familiar with the skill and can not deviate from the actual situation of the case. In the case of spirit and scope, 2 changes and modifications are made. Please refer to FIG. 2, FIG. 3, and FIG. 4.
