Description
Technical field
The utility model belongs to the technical field that unpowered vehicle is vehicles such as bicycle, three-wheel vehicle, further is the lever-type force-saving driving rod for bicycle of a kind 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.Chinese patent ZL01121438.2 discloses a kind of bicycle power-saving devices, but its concrete unreasonable structure can not reach the labor-saving effect.
The utility model content
In order to address the above problem, the utility model provides a kind of force-saving driving rod for bicycle, and it can increase the length of the transmission arm of force, thereby reaches the labour-saving purpose.
The technical solution of the utility model is to constitute like this, it is characterized in that: comprise drive link, one end of drive link is connected with pedal or handle apparatus, the other end is rotationally connected with two " Z " font connecting rods respectively apart from the different length position of drive link termination, the axis of three interconnect function points is parallel to each other on the drive link, and the interconnect function point of pedal or handle apparatus and drive link arrive from its immediate " Z " font connecting rod and drive link be rotationally connected a little distance of shaft centers greater than two " Z " font connecting rods and drive link be rotationally connected a little between distance of shaft centers; 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 first cross bar and drive link are rotationally connected, second cross bar is used for being rotationally connected with cycle frame, and the distance of shaft centers between the corresponding cross bar of two " Z " font connecting rods all equates; With also be fixedly connected with the transmission chain drum on second cross bar of pedal or handle apparatus immediate " Z " font connecting rod and be used to drive bicycle freewheel or drive 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 (the bicycle shift chain drum is formed by fixedly connecting for the multi-disc chain drum, and another sheet chain drum in the speed-changing chain guard is connected with bicycle freewheel by another driving chain again) by driving chain and bicycle freewheel or with a slice chain drum in the bicycle shift chain drum.When stepping on the rotation of device with pedal (or shaking handle apparatus) drive drive link, because second cross bar and the cycle frame of two " Z " font connecting rods are rotationally connected, and the distance of shaft centers between the corresponding cross bar of two " Z " font connecting rods all equates, therefore two " Z " font connecting rods all can only move in a circle around the axis of its second cross bar, thereby rotation by the affixed transmission chain drum of drive and second cross bar of one of them " Z " font connecting rod, then driving bicycle freewheel rotates, perhaps drive the bicycle shift chain drum and rotate, drive bicycle freewheel by speed-changing chain guard again and rotate.
Than prior art, the utility model is rotationally connected owing to " Z " font connecting rod and drive link are set, therefore can prolong pedal or handle apparatus greatly and be connected a little the length of being rotationally connected of " Z " the font connecting rod of transmission chain drum and drive link with the interconnect function point arrival of drive link, promptly increased the length of the transmission arm of force, make its length, therefore can reach the labour-saving purpose much larger than existing bicycle chain drum to pedal (or handle).
