Abstract
The utility model relates to a double-crank power saving mechanism of a bicycle, which is arranged on a bicycle and is in a left and right symmetrical structure. The structure of each surface is totally composed of a transverse beam, a suspension rod, a horizontal rod, an additionally arranged crank, a crank of an original bicycle and a crank shaft. The front end of the transverse beam is fixed onto a bicycle frame; the back end of the transverse beam is fixed onto a clothes rack of the bicycle; the upper end of the suspension rod is hinged with the transverse beam, and the lower end of the horizontal rod is hinged with the back end of the horizontal rod. The front end of the horizontal rod and the back part of the additionally arranged crank are fixed to be integration; the front end of the additionally arranged crank is provided with pedals; the back end of the additionally arranged crank is connected with the lower end of the crank of an original bicycle by the crank shaft, and the crank of the original vehicle is connected with a center shaft. When the pedals are stepped in the process of riding the bicycle and the crank of an original bicycle makes circumferential movement, according to a positive rotation rule, the additionally arranged crank increases on the crank of an original vehicle when n is from (0 degree to 180 degrees), and the additionally arranged crank shortens when n is from (180 degrees to 360 degrees). The utility model obtains the goals that when the bicycle is ridden, the crank is lengthened and the labor is saved. When the pedals are not stepped, the crank can shorten and can not touch the ground. The utility model can make riders increase riding speed or save physical strength about one third.
Description
Technical field
A kind of driving device of the vehicle, particularly a kind of bicycle double crank effort-saving mechanism.
Technical background
For reaching labour-saving purpose by bike, patent documentation has provided several movable cranks and can slide on fixed crank, and in order to increase the technical scheme of crank length, this kind scheme is easy to contact to earth and poor effect when extending owing to movable crank.
Summary of the invention
Task of the present utility model is to provide a kind of bicycle double crank effort-saving mechanism.This bicycle double crank effort-saving mechanism scrunches pedal by bike, and former car crank is being pressed circular path when action, and it adds and cranks increasing when n (0 °～180 °) by the dextrorotation curve law on the former car crank, shortens when n (180 °～360 °).Laborsaving in order to reach when scrunching pedal by bike the crank lengthening; Crank shortens the purpose of not contacting to earth when not scrunching pedal.
Task of the present utility model can realize that its implementation is that bicycle double crank effort-saving mechanism is installed on the bicycle, and is connected with bicycle middle shaft.Bicycle double crank effort-saving mechanism is characterised in that bicycle double crank effort-saving mechanism is the left-right symmetric structure, every structure by crossbeam, suspension rod, horizon bar, add crank, former car crank and crank shaft form.The front end of crossbeam is fixed on the vehicle frame of bicycle, and the rear end is fixed on the clothes hanger of bicycle.The upper end and the crossbeam of suspension rod are hinged, and the rear end of lower end and horizon bar is hinged.The front end of horizon bar with add the rear portion that cranks and be fixed into one.Add the front end that cranks pedal is housed, the rear end is rotated with former car crank lower end by crank shaft and is connected.Former car crank is connected with axis.The length of suspension rod is greater than the length of former car crank.During work, the reverse each other action of left and right sides structure.
Bicycle double crank effort-saving mechanism of the present utility model, simple in structure, reasonable in design.The bicycle of this bicycle double crank effort-saving mechanism is housed, under same speed by bike, can makes the rider save about 1/3rd muscle power.Otherwise, then can make the speed of a motor vehicle improve about 1/3rd if by bike with same strength.
Description of drawings
Provide the embodiment of the utility model bicycle double crank effort-saving mechanism below by accompanying drawing.
Fig. 1 is the main scheme drawing that the bicycle of bicycle double crank effort-saving mechanism is housed.
Fig. 2 is that A among Fig. 1 is to view.
Fig. 3 is the principle schematic of bicycle double crank effort-saving mechanism.
Among the figure, 1 left crossbeam, 2 right suspension rods, 3 left suspension rods, 4 left horizon bars, 5 left sides add crank, 6 left pedals, 7 left former car cranks, 8 right horizon bars, 9 right former car cranks, 10 right sides add crank, 11 right pedal, 12 vehicle frames, 13 clothes hangers, 14 axis, 15 right crossbeams, a bolt, b crank shaft.
The specific embodiment
Referring to Fig. 1, Fig. 2.Bicycle double crank effort-saving mechanism is installed on the bicycle, becomes one with bicycle.Bicycle double crank effort-saving mechanism is made up of symmetrical two-part structure, the left side by left crossbeam 1, left suspension rod 3, left horizon bar 4, a left side add crank 5, left former car crank 7, crank shaft b and left pedal 6 form.The front end of left side crossbeam 1 is fixed on the vehicle frame 12 of bicycle, and the rear end is fixed on the clothes hanger 13 of bicycle.The upper end and the left crossbeam 1 of left side suspension rod 3 are hinged, and the rear end of lower end and left horizon bar 4 is hinged.The front end of left side horizon bar 4 adds 5 the rear portion of cranking with a left side and is fixed into one by bolt of rear end plate a.A left side adds 5 front ends that crank left pedal 6 is housed, and the rear end is rotated through bearing with left former car crank 7 lower ends by crank shaft b and connected.The former car crank 7 in a left side is connected with bicycle middle shaft 14.The right side by right crossbeam 15, right suspension rod 2, right horizon bar 8, the right side add crank 10, right former car crank 9, crank shaft b and right pedal 11 form.The front end of right crossbeam 15 is fixed on the vehicle frame 12 of bicycle, and the rear end is fixed on the clothes hanger 13 of bicycle.The upper end and the right crossbeam 15 of right suspension rod 2 are hinged, and the rear end of lower end and right horizon bar 8 is hinged.The front end of right horizon bar 8 is fixed into one with right 10 the rear portion of cranking that adds by bolt of rear end plate a.The right side adds 10 front ends that crank right pedal 11 is housed, and the rear end is rotated by bearing with right former car crank 9 lower ends by crank shaft b and connected.Right former car crank 9 is connected with bicycle middle shaft 14.Rotate the dead angle for preventing, the length of two suspension rods 2,3 must be greater than the length of former car crank 7,9.During work, the reverse each other action of structure on two sides.
Referring to Fig. 3.End position after left suspension rod 3 is flapped toward, when left horizon bar 4 was horizontal substantially, a left side added to crank and 5 is in overlap condition with the former car crank 7 in a left side backward.A left side can being added this moment cranks 5 regards as and is in 0 ° of position.From this position, in the rotating process, a left side adds 5 elongations on the former car crank 7 in a left side constantly that crank to left former car crank 7 conter clockwises forward, and when left former car crank 7 turned to 180 ° of positions, a left side added to crank and 5 is elongated to end position.The former car crank 7 in a left side is rotated further 360 ° the process from 180 °, and a left side adds to crank 5 constantly shortens on the former car crank 7 in a left side, and when left former car crank 7 forwarded 360 ° of positions to, a left side added to crank 5 to shorten to once more with left former car crank 7 and is in overlap condition.The moving circle of revolution like this, a left side add to crank 5 to finish once and elongate or shorten, thereby have reached the lengthening crank, and be laborsaving by bike; Shorten crank, the purpose that crank does not contact to earth in the time of by bike.
