Abstract
The utility model relates to a balancer lever assisted horizontal bicycle, belonging to the class of bicycles. The utility model is composed of a bent arced bicycle frame, a front and a back wheels, a fork and a handle bar which are arranged at the back part of the bicycle frame, a saddle beneath the back part of the bicycle frame, a front and a back wheel brakes, a gear box at the front part of the bicycle frame, pedal levers at both sides of the gear box, and a driving mechanism driving the front wheel via connecting rods hinged at the side face of each pedal lever, crankshafts hinged at the lower ends of the connecting rods, a change gear set, umbrella teeth, a drive shaft and end umbrella teeth. The bicycle has the advantages that the saddle low and stable center of gravity; the utility model has labor saving and comfort for treading and driving.
Description
The utility model belongs to Bicycle.
Existing bicycle is made up of vehicle frame, front and back wheel, handlebar and car fork, vehicle seat, front and back hub brake, transmission device.Handlebar is in the place ahead of vehicle frame, and vehicle seat is positioned at the top of vehicle frame and wheel, and transmission device is by rotating crank and sprocket wheel and link chain mechanism.This bicycle has the too high crank in seat, and bipod steps pedal gyroscopic movement effort.
The purpose of this utility model is: provide a kind of seat low center of gravity steady, scrunch the laborsaving comfortable bicycle of transmission.
Technical measures of the present utility model are: based on the bicycle of being made up of vehicle frame, front and back wheel, handlebar and car fork, vehicle seat, front and back hub brake, transmission device; Vehicle frame is a curved arc shape, and vehicle seat is in the lower rear of vehicle frame, and car is pitched the rear end in vehicle frame, and handlebar is the upper end that is fixed on the car fork of tommy bar shape; Transmission device is: by the gear case of vehicle frame front upper, the treadle that be equipped with respectively the gear case both sides, each treadle upper side is the pivotally attached connecting rod respectively, the lower end of each connecting rod is hinged on crankshaft two end respectively, the change-gear set of the gear mesh at bent axle middle part, change-gear set is by the transmission device of umbrella tooth and transmission shaft and the rotation of terminal umbrella tooth driving front vehicle wheel.
Bicycle of the present utility model has the vehicle seat low center of gravity surely, back and forth to scrunch laborsaving and comfortable good effect.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a local transmission scheme drawing of the present utility model.
Drawing explanation and embodiment are described below: 13 is vehicle frames among the figure, and vehicle frame 13 is curved arc shapes, and vehicle frame can be single-piece, also can be divided into front vehicle frame and back vehicle frame and peg graft mutually and form, and forms the vehicle frame that stretches.The 14th, vehicle seat is fixed on the lower rear of vehicle frame 13.Car fork 15 is in the rear end of vehicle frame 13, and handlebar 3 is upper ends that are fixed on car fork 15 of tommy bar shape.The transmission device of bicycle of the present utility model is the transmission device of treadle formula, transmission device is by the gear case 5 that is fixed on vehicle frame 13 front upper, gear case 5 both sides are equipped with treadle 8 and 12 respectively, each treadle upper side is hinged with connecting rod 9 respectively, the lower end of each connecting rod 9 is hinged on bent axle 10 two ends respectively, the gear mesh change-gear set at bent axle 10 middle parts, change-gear set drives front vehicle wheel 19 and rotates by umbrella tooth and transmission shaft 7, terminal umbrella tooth 18.Existing bicycle is that front vehicle wheel turns to, rear wheel is by chain wheel drive, and bicycle of the present utility model is opposite, and handlebar 3 and rear wheel 16 turn to, front vehicle wheel 19 is driven by the umbrella tooth.2 is brake levers of rear wheel 16 among the figure.For comfortable, on the vehicle frame 13 at vehicle seat 14 rear portions, backrest 1 is housed.The 17th, front vehicle wheel 19 step on flashboard.For attractive in appearance and safety, windshield 6 is housed in the front portion of vehicle frame.Ride and use this bicycle, bipod alternately scrunches left and right sides treadle 8 and 12 forward, when a treadle 8 travels forward, drivening rod 9 travels forward, the bottom of connecting rod 9 drives bent axle 10 again and rotates, and the gear at bent axle 10 middle parts advances front-wheel 19 rotations by the umbrella tooth 18 of variable gear, umbrella tooth and transmission shaft 7, front vehicle wheel 19.When a treadle 8 was stepped forward, 12 of another treadles are motion backward, and what two treadles 8 and 12 replaced before and after being is swinging, and this alternating movement can be adopted the lead connection structure; Also can adopt the rack-and-gear serial verb construction of Fig. 2; Treadle 8 and 12 upper ends by transverse axis 22 and 21 and gear case 5 be hinged, each transverse axis 22 and 21 inner ends have a miniature gears respectively, two miniature gearss are meshed with the interior up and down tooth bar 20 of square shape respectively, and when a treadle 8 was swung forward, the miniature gears of front end promoted tooth bar 20 to front slide.At this moment balancing device tooth bar 20 promotes another treadle 12 again and miniature gears moves in the opposite direction from the below.Two treadles 8 and 12 have only to be pedaled forward and are only main motion, and drivening rod 9 rotates bent axle 10, by gear umbrella tooth, turning cylinder 7, terminal umbrella tooth 18 front vehicle wheel 19 is rotated.4 is control lever of variable gear among the figure.The 11st, the case lid of gear case.
