Description of the invention: [Technical field to which the invention pertains] The present invention relates to a ratchet-like structure (2), and more particularly to a transmission mechanism for a light rear wheel of a vehicle, the limit member of which keeps the ratchet In the normally closed state, the studs of the ratchet teeth and the damper member are in a displacement relationship, that is, the pedals are not driven when the wheels are reversed, and no noise is generated. [Prior Art] I know the number of ratchet structures as shown in Figures 8 and 9, which include: a ratchet disk (60), a flower hub (70) and a mandrel (8 inch), one The ratchet disk (60) is a tubular body, and a toothed disc (61) and a ratchet seat (62) are arranged on the circumferential surface, and a plurality of ratchet teeth are arranged on the circumferential surface of the ratchet seat (62). The hole (621)' is provided with a plurality of ratchet teeth (63), and an elastic member (64) is disposed between the ratchet tooth (63) and the ratchet hole (62), and a flower hub (70) is a The tubular body has a ratchet disc chamber (71) on one side and a helical tooth surface (711) in the ratchet disc chamber (71). A mandrel (80) is a cylinder, and the front and rear ends are An external thread is provided, and a stop ring (81) is protruded from a suitable portion of the segment, and a plurality of bearings (82) can be disposed between the ratchet disk (60), the flower hub (70) and the spindle (80). And a positioning member (83), the mandrel (80) is fixed in the flower (70) by a bearing (82), and the ratchet seat (62) is placed in the ratchet disk chamber of the flower (70) ( 71) Medium. In the actual operation, the ratchet (63) is pushed outward by the elastic member (64), and the normal state remains open and interferes with the helical tooth surface (711) of the flower hub (7〇) when rotating When the ratchet disk (60) is rotated forward, the ratchet (63) is against the oblique tooth surface (711), and the ratchet disk (60) is transmitted through the ratchet (63) to drive the flower hub (7〇). When the ratchet (61) is reversed, the ratchet (63) 5 is actuated by the helical tooth surface (711) and the miscellaneous member (64) to produce a pendulum motion effect, and the flower hub (70) When the ratchet (63) is rotated, the ratchet (63) is not driven by the flower (10), and when the flower (10) is reversed, the spine (10) is It will be pushed in the opposite direction by the helical tooth surface (711), causing the ratchet disk (6〇) to reverse. Looking at the above-mentioned conventional structure, it is not difficult to find that there are still some shortcomings. The main reasons are as follows: / (I) When the flower hub (70) is reversed, the ratchet (63) is subjected to helical teeth. The surface (711) and the elastic member (64) act to generate a reverse swing effect, and the ratchet disc (6〇) is not interlocked with the flower (7〇), when the vehicle is moved backward or the pedal is stepped. When the plate is reversed, the friction and noise of the ratchet and the helical tooth surface will be generated. (1) When the flower is compared with (70), the ratchet (63) is reversely urged by the inclined tooth surface (711), causing the ratchet disk (60) to drive the pedal to reverse. When the bicycle is used to retreat, the pedal is applied to rotate when the bicycle is retracted, and the rotation of the pedal is easy to accidentally injure the user. When applied to the electric bicycle, the driving motor is connected to the ratchet disc (60). ), will make the process of moving the electric bicycle back is quite laborious. In view of this, the present inventors have been engaged in the manufacturing development and design experience of related products for many years, and have made the present invention a practical and practical result after detailed design and careful evaluation.

Threaded into the inner threaded section (42) of the toothed disc member (40), a mandrel (50) is threaded with a bearing (52), and passes through the sprocket member (40), the damper member (30), and the helical tooth The center of the ring (43) and the connecting section (134) is connected by a thread to a connecting rod (12) located in the hub (1), and the bearing (52) is connected to the connecting rod (12). The inner side of the segment (134) and the fixing member (45). The actual operation situation is continued as shown in Figures 3, 4, and 5. Figure 1. A ratchet ratchet structure (2) is installed at the rear wheel of an electric bicycle or bicycle, and its flower hub (1〇) is attached. The wheel (11) is connected to the wheel and the connecting rod (12) and the mandrel (50) are fixedly fastened to the frame 1351357. The toothed disc member (40) is sleeved and driven by a chain. And the ratchet (15) on the ratchet seat (a) is elastically held by the restricted position member (14) to maintain an inwardly closed shape, and when the toothed disc member (40) is driven to rotate forward by the key strip, the damping member ( 30) The damping hole (32) is provided with an elastic piece (33), and the convex piece (331) of the elastic piece (33) is in contact with the inner edge of the toothed plate member (4〇), so that the toothed plate member (40) ) driving the damper member (30) to rotate 'the damper member (31) is slidably connected to the boss (153) of the ratchet (15), and the damper member (30) is rotated forward The push rod (丨53) is moved outward, that is, the ratchet (15) is deployed outward, and the unfolded ratchet (15) is clamped on the oblique tooth surface (44) of the helical ring (43), that is, Can drive the flower hub (1〇) and the wheel rotates forward synchronously The member (30) and the toothed disc member (40) have a certain degree of frictional resistance. When the damper member (30) pushes the ratchet (13), it is blocked by the stud (153) and the ratchet The seat (13) rotates synchronously. On the contrary, when the toothed disc member (40) is reversed, the ratchet teeth (15) are closed, so that the helical ring (43) cannot drive the ratchet seat (13), that is, The noise of the ratchet (15) and the helical tooth surface (44) is generated. Please see from the 3rd, 6th, and 7th diagrams. When the gear unit (4〇) has no power output, when the electric bicycle and the bicycle move backward, the wheel drives a flower hub (10), and The flower hub (10) interlocks the ratchet seat (13), and the ratchet (15) is fixed on the ratchet seat (13) by a ratchet pivot point (152) fixed to the ratchet shaft hole (135) 'the ratchet (15) The protruding post (153) is slid to the inner end of the damper (31) of the damper member (30), and the elastic piece (33) of the damper member (32) is resisted by the sprocket member (40). Damping even if the ratchet (15) is closed in the ratchet seat (13) and the flower is idling by itself (10) and the thrust of the stud (153) is greater than the resistance of the toothed disc member (40) The piece (30) rotates synchronously with the flower hub (10). Since the ratchet (15) is used for the restricted position member (14) for the 1351357, the ratchet (15) remains attached to the ratchet seat (13). In this state, by the structure, when the electric bicycle or the bicycle is pushed, the flower hub (10) cannot drive the rotation of the toothed disc member (4〇), so that the front and rear rotations of the flower hub (ίο) will not drive the toothed disc. Piece (4〇), when applied to a bicycle, its pedals will not Rotating and accidentally injuring the user, and when applied to an electric bicycle, will drive the motor hub (1 〇), and the process of the 俾崎 axis electric bicycle is more labor-saving. In summary, the present invention has achieved a breakthrough structural design, and has an improved invention content. At the same time, it can achieve the bribe and progress of the production and the invention is not found in any publication, and also has _ sex When it comes to the provisions of the shameful law, Sharp Law proposes that the invention patent application review committee grants legal patent rights, and is praying. Only those mentioned above are only for the purpose of this (4) - Touching the implementation of the invention can not be limited to the scope of the implementation of the present invention; that is, the average change and modification of the special bicycles according to the invention should still belong to this Within the scope of the invention patent. 12 1351357 [Simplified description of the drawings] Fig. 1 is a perspective view of the present invention.
