Description
Technical field
The utility model belongs to the technical field that unpowered vehicle is vehicles such as bicycle, three-wheel vehicle, further is a kind of labor-saving transmission mechanism of bike of unpowered vehicle.
Background technology
Existing ordinary bicycle is used for the length of pedal bonded assembly single arm(ed) lever shorter, not too laborsaving owing to trample the restriction of position on the chain drum.Applicant of the present utility model is that 200620158888.2 Chinese utility model patent discloses a kind of " bicycle labor saving Transmission " in the patent No. of on November 9th, 2006 application, the connection transmission of 3 points of this device main dependence drive link drives bicycle and moves ahead: wherein the 1st point of connection of drive link and the 2nd point of connection are rotationally connected with two " Z " font connecting rods respectively, the 3rd point of connection is connected with pedal or handle apparatus, make 3 point of connection of drive link make circular movement synchronously by the application force that acts on pedal or handle apparatus, thereby bicycle is moved ahead, yet find through experiment: when application force down when the 3rd point of connection of drive link is pedal or handle apparatus (being directed downwards perpendicular to paper as shown), the 1st point of connection in drive link top can up change (as shown perpendicular to the paper direction upwards), the 2nd resistance that point of connection down rotates in below, drive link top is very big, and be used for making the 2nd thrust that point of connection down rotates very little, therefore two " Z " font connecting rods are not easy to rotate in the same way around its second cross bar axle center, drive link just looks like lever two counter-rotating and the strong point is motionless, so this structure is not easy to make 3 point of connection of drive link to make synchronous circular movement, also with regard to out of reach labour-saving effect.
The utility model content
In order to address the above problem, the utility model provides a kind of labor-saving transmission mechanism of bike, and it not only can make the rotation of Transmission drive " Z " font connecting rod freely convenient, and can further improve the labor-saving effect.
The technical solution of the utility model is to constitute like this, a kind of labor-saving transmission mechanism of bike, it comprises Transmission, be connected in the pedal or the handle apparatus of Transmission one end, be connected in a pair of " Z " font connecting rod of the Transmission other end, and pedal or handle apparatus and Transmission bonded assembly interconnect function line of centers and two " Z " font connecting rods and Transmission bonded assembly interconnect function line of centers are parallel to each other; Each " Z " font connecting rod includes a pair of cross bar that is parallel to each other and is fixed in vertical rod between two cross bars, wherein second cross bar all is used for being rotationally connected with cycle frame, and the distance of shaft centers between first cross bar of two " Z " font connecting rods equals the distance of shaft centers between second cross bar; It is characterized in that: described Transmission is made up of connecting panel and power rail, first cross bar of two " Z " font connecting rods is rotationally connected with the connecting panel two ends respectively, one end of power rail is fixedly connected on the connecting panel middle part, the other end of power rail is connected with pedal or handle apparatus, and first cross bar of two " Z " font connecting rods and the position that is rotationally connected of connecting panel lay respectively at the both sides of captiveing joint the position of power rail and connecting panel; The second cross bar axle center that one of them " Z " font connecting rod is fixedly connected with this " Z " font connecting rod is the transmission chain drum of center of turn, and described transmission chain drum is used for driving bicycle freewheel or drives bicycle freewheel by the bicycle shift chain drum.
During use, second cross bar with two " Z " font connecting rods is connected bicycle front end or rear end earlier, itself and cycle frame are rotationally connected, again the transmission chain drum is connected with bicycle freewheel by driving chain, perhaps the transmission chain drum is connected with a slice chain drum in the bicycle shift chain drum (the bicycle shift chain drum is formed by fixedly connecting for the multi-disc chain drum), then makes another sheet chain drum in the bicycle shift chain drum be connected (bicycle shift chain drum only play guide wheel effect) here with bicycle freewheel by another driving chain.When stepping on the rotation of device with pedal (or shaking handle apparatus) drive Transmission, because second cross bar and the cycle frame of two " Z " font connecting rods are rotationally connected, and the distance of shaft centers between first cross bar of two " Z " font connecting rods equals the distance of shaft centers between second cross bar, therefore two " Z " font connecting rods all can only be respectively move in a circle around the axial line of its second cross bar, thereby by driving the rotation of the transmission chain drum of captiveing joint with one of them " Z " font connecting rod, driving bicycle freewheel rotates, perhaps rotate, drive bicycle freewheel by the bicycle shift chain drum again and rotate by the moving bicycle shift chain drum of messenger chain dribbling.
Than prior art, the utility model is owing to be arranged to Transmission to be made up of connecting panel and power rail, first cross bar of two " Z " font connecting rods is rotationally connected with the connecting panel two ends respectively, one end of power rail is fixedly connected on the connecting panel middle part, the other end of power rail is connected with pedal or handle apparatus, and first cross bar of two " Z " font connecting rods and the position that is rotationally connected of connecting panel lay respectively at the both sides of captiveing joint the position of power rail and connecting panel; Therefore, when making (the vertical as shown in Figure 1 paper is directed downwards) commentaries on classics downwards of pedal or handle apparatus by application force, the downward application force that the power rail upper end applies connecting panel is transferred to the middle part (fixed connection point) of connecting panel, and make first cross bar of two " Z " font connecting rods become as a whole by connecting panel, first cross bar that makes connecting panel can drive two " Z " font connecting rods simultaneously moves downward, can make pedal or handle apparatus when rotating, drive two " Z " font connecting rods smoothly like this and make synchronous circular movement, because this structure arm of force is longer and power rail can extend as required, therefore really reached the labor-saving effect in addition.
