Abstract
The utility model relates to exercise and fitness equipment, particularly to a novel sport bicycle. The novel sport bicycle comprises a driving device which comprises pedals, a chain, a combined driving gear and a connecting rod, wherein the combined driving gear comprises a small flywheel of a rear wheel, inertial wheels on the two sides of the combined driving gear and a big flywheel welded on the bicycle frame; the big flywheel and the inertial wheel are connected through the chain; the connecting rod is welded on the central shaft of the big flywheel; the other end of the connecting rod isconnected on a moving point hook on a pedal big arm; and the tail ends on the pedal big arms on two sides are connected through a movable bearing. The novel sport bicycle has the advantages that thetransmission distance is shortened through the vertical movement of pedals, going forward and backward can be realized, the bicycle can go faster and faster relying on inertia, and the purposes of exercise and entertainment are achieved for a user, and meanwhile, fast and labor-saving bicycle riding is achieved.
Description
One, technical field
The utility model relates to exercise and fitness equipment, particularly a kind of novel sporting car.
Two, background technology
At present, the children's sport car with become person bicycle all to use chain drive, general driving device is made up of pedal, crank, hinge wheel, chain, flywheel, bicyclist's both feet are pedaled the pedal on a pair of reverse crank alternately, make crank make circular movement, through hinge wheel, chain, flywheel transmission, drive trailing wheel and rotate, drive bicycle and advance, its shortcoming is the transmission distance, trample effort, complex structure, and make that the volume of perambulator and bicycle is bigger, also heavy; Simultaneously, traditional chain gearing can only make sporting car advance, if when wanting backward the drawback movement car, can only get off and carry out backward, makes troubles to the drivers, and lacks recreational and gymnastics.Therefore, provide a kind of small volume and less weight, be easy to drive and can be fast and the sporting car that travels flexibly, to satisfy the needs of people's body-building and amusement to people.
Three, summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and a kind of novel sporting car is provided, and this novel sporting car small volume and less weight, is easy to drive, and can advance and also can fall back, and can satisfy the needs of people's body-building and amusement.
The technical solution of the utility model is: a kind of novel sporting car, comprise actuating device, actuating device is made up of pedal, chain, combination moving gear, connecting rod, it is characterized in that: described combination moving gear comprises the small flywheel of rear wheel and the inertia wheel of both sides thereof, and form by the big flywheel that the chain bonded assembly is welded on the vehicle frame with the right side inertia wheel, the center shaft of big flywheel is welded with connecting rod, the moving point that the other end of connecting rod is connected on the big arm of pedal is colluded, and the end of the big arm of pedal of both sides connects by free bearing.
The position of above-mentioned big flywheel apart from the angle of back wheels of vehicle width between centers between 45 °-70 °.
Above-mentioned connecting rod is made up of the two-section small rod, connects by free bearing between the two.
The beneficial effects of the utility model: by the pedal up-and-down movement, shorten the transmission distance, can realize advancing and fall back, rely on the inertia can be more and more faster, increased people's gymnastics and recreational.Reach simultaneously ride laborsaving, the fast speed purpose.
Four, description of drawings
Fig. 1 the utility model structural representation
Five, the specific embodiment
As shown in Figure 1, actuating device is made up of pedal (9), chain (3), combination moving gear, connecting rod (2), described combination moving gear comprises the small flywheel (6) of rear wheel and the inertia wheel (5) of both sides thereof, and form by the big flywheel (1) that chain (3) bonded assembly is welded on the vehicle frame (8) with right side inertia wheel (5), the center shaft (7) of big flywheel (1) is welded with connecting rod (2), the moving point that the other end of connecting rod (2) is connected on the big arm of pedal (10) is colluded on (12), and the end of the big arm of the pedal of both sides (11) connects by free bearing (4).Between 45 °-70 °, the connecting rod (2) that is welded on big flywheel (1) center shaft (7) is made up of the two-section small rod apart from the angle of back wheels of vehicle width between centers in the position of big flywheel (1), between the two by free bearing (11) connection.
When trampling the pedal motion up and down, the combination moving gear that drives rear wheel by connecting rod (2) moves, and makes sporting car realize advancing or retreating.
The big arm of pedal (10) has the bending of certain angle, and angle can realize the most laborsaving at 90 degree-155 degree when trampling pedal.
The above only is an embodiment of the present utility model, and unrestricted protection domain of the present utility model.
Claims (3)
1, a kind of novel sporting car, comprise actuating device, actuating device is made up of pedal, chain, combination moving gear, connecting rod, it is characterized in that: described combination moving gear comprises the small flywheel of rear wheel and the inertia wheel of both sides thereof, and form by the big flywheel that the chain bonded assembly is welded on the vehicle frame with the right side inertia wheel, the center shaft of big flywheel is welded with connecting rod, and the moving point that the other end of connecting rod is connected on the big arm of pedal is colluded, and the end of the big arm of pedal of both sides connects by free bearing.
