Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in further detail.
Fig. 1, Fig. 2, shown in Fig. 7 and Figure 10 is a detailed description of the invention of bicycle hydraulic rear chiain-moving device, have employed hydraulic way to transmit the manipulation force of finger, when hydraulic oil enters oil cylinder seat 3 by tubing interface 18, pressure promotion piston 19 being overcome to extension spring 21 is extrapolated, piston 19 withstands on sleeve base 5 all the time, sleeve base 5 is just promoted to advance, the column part of sleeve base 5 is pressed against with conversion head 6 by angle screw 9 and angle nut 10, so conversion head 6 just drives wheel bracket 7 and guide wheel 8 to march forward, just complete one and dial chain action, namely complete one by cone pulley smallest pieces 15 to group chain action in the most large stretch of 16 directions of cone pulley；When hydraulic oil flows out oil cylinder seat 3 by tubing interface 18, under the pressure of extension spring 21 and the synergy of atmospheric pressure, piston 19 will return in the oil cylinder of oil cylinder seat 3, so sleeve base 5, conversion head 6, wheel bracket 7 and guide wheel 8 all can return a corresponding distance, namely complete one and moved back gear action by cone pulley the most large stretch of 16 to cone pulley smallest pieces 15 direction.
Fig. 1, Fig. 5 and Fig. 6 illustrate that fixing seat 1 one end is fixed in Rear frame 17, and the other end is by adjusting scope screw 13 and adjusting scope nut 14 to be pressed against with slide block 2；Fix and be tightly pressed together by screw between seat 1 and slide block 2, tighten tune scope screw 13 by unscrewing and adjust scope nut 14, artificial can change is fixed between seat 1 and slide block 2 around the angle adjusting scope screw 13 axis, change the fixing angle around tune scope screw 13 axis between seat 1 and slide block 2, namely changing piston 19 movement locus and the angle of cone pulley axis, namely change rear chiain-moving device dials chain scope.
Fig. 2, Fig. 3, Fig. 8 and Fig. 9 illustrate that slide block 2 is formed by shape stretching, it is installed in the sliding rail of oil cylinder seat 3, and it has a screw hole, is provided with adjusted position screw 11 in screw hole, stopper 12 is fixed on oil cylinder seat 3, and stopper 12 blocks the position of adjusted position nut 11；Slide block 2 under the turning effort of adjusted position screw 11, its slip of retreating in the sliding rail of oil cylinder seat 3, change the guide wheel 8 position relative to cone pulley of rear chiain-moving device.
Fig. 2 and Fig. 3 illustrates that the inwall of sliding sleeve 4 is slidably matched with column 20 on oil cylinder seat 3, it is impossible to relatively rotating, the lower end of sliding sleeve 4 is fixed together with sleeve base 5；Sliding sleeve 4 has support and positioning action.
Fig. 4 illustrates that the column part of sleeve base 5 is pressed against with conversion head 6 by angle screw 9 and angle nut 10；Angle screw 9 and angle nut 10 is tightened by unscrewing, artificially can change the angle of axis around angle screw 9 between sleeve base 5 and conversion head 6, namely by the adjustment of the angle around angle screw 9 axis, can ensure that guide wheel 8 and cone pulley are parallel to each other accurately.
Figure 10 is the position description of the relevant extension spring of this detailed description of the invention, and oil cylinder seat 3 is caught in one end of extension spring 21, and the other end catches on sleeve base 5, remains the pressure to piston 19.
In a word, this utility model bicycle hydraulic rear chiain-moving device by adjusting 3 screws and can realize the chain scope of dialling of rear chiain-moving device, the guide wheel 8 of rear chiain-moving device relative to the position of cone pulley and ensures that guide wheel 8 and cone pulley are parallel to each other the adjustment in terms of these three accurately.This is a simplified compared with the adjustment of the steel wire pull line formula rear chiain-moving device of tradition quadric chain, and this utility model have employed the method for the steel wire pull line formula being totally different from tradition quadric chain, alleviates feel, convenient manipulation.
