Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5 and Fig. 6, a kind of bicycle transmission mechanism described in the utility model, comprise rectangular spline universal joint (1), backing pin (2), spring (10), catch (8), cross axle (3), involute-type spline universal joint (5), opening cartridge type pin (7), outer involute-type splined shaft (9), interior involute-type splined shaft (6), also comprise the spacing jump ring (5) of fixed cross axle, described rectangular spline universal joint (1), on have backing pin groove, be used for limit cross axle (3) position, described cross axle (3) is inserted in rectangular spline universal joint (1) axis hole, adopts transition fit to meet the requirement of stable drive, described cross axle (3) the other end is inserted in involute-type spline universal joint (5) axis hole, and moment of torsion passes to involute-type spline universal joint (5) by cross axle (3), described involute-type spline universal joint (5) one end is provided with pin-and-hole (601), opening cartridge type pin (7) is installed in described pin-and-hole (601), described cartridge type pin (7) connects involute-type universal joint (5) and outer involute splined shaft (9), cartridge type cotter pin (7) has elasticity and is convenient to dismounting and connects stable, and such moment of torsion passes to outer involute splined shaft (9) by involute-type universal joint (5), described outer involute splined shaft (9) and interior involute splined shaft (6) pass through splined, moment of torsion passes to interior involute splined shaft (6), and interior involute splined shaft (6) passes through splined with the involute splines universal joint (5) of the other end, described splined is by the position of involute splined shaft (6) and involute splines universal joint (5) in cartridge type cotter pin (7) restriction.
Described backing pin hole is built with backing pin (2), spring (10) and catch (8), large one end, backing pin bore dia one end is little, the large end of pin-and-hole is provided with catch groove, backing pin (2) small end stretches out outside pin-and-hole, large end contacts with spring (10), and spring (10) is limited in pin-and-hole by catch (8).
