Abstract
The utility model relates to a front two-wheel bicycle, which comprises a triangle frame, and a hand-bar rotationally connected with the front end of the triangle frame. A I-shaped balance frame is arranged on the front portion of the triangle frame, and is formed by a upper horizontal pole and a lower horizontal pole and a vertical pole which is hinged on the middle portion of the upper and the lower horizontal poles, and the vertical pole is fixedly connected with the hand-bar. The two ends of the upper and the lower horizontal poles are respectively hinged with a fixed sleeve. A left-front wheel frame is fixedly connected by the two fixed sleeves on the left sides of the upper and the lower horizontal poles, and a right-back wheel frame is fixedly connected by the two fixed sleeves on the right sides of the upper and the lower horizontal poles. A left and a right front wheels are respectively arranged on the lower portion of the left and the right front wheel frames. The utility model has good stability and flexible deflection, and the balance frame can automatically adjust the two front wheel frames according to the contact condition between the two front wheels and ground when the ground having lateral inclination angle, thereby guaranteeing the two front wheels contact with the ground simultaneously, which increases safety, and avoids slipping, and is specially applicable to older persons and children. In addition, the utility model has simple structure, convenient installment and maintenance, and higher practicability.
Description
Technical field
The utility model relates to a kind of bicycle, particularly a kind of preceding bicycle.
Background technology
Bicycle with its environmental protection, body-building, flexibly, purchase and operating costs be low, easy to maintenance etc., and characteristics are liked by masses deeply, are one of people's main walking-replacing tools of going on a journey.Existing bicycle generally has spider, the place ahead of spider is rotatably connected to handlebar, the handlebar bottom connects front wheel carrier, rotate on the front wheel carrier and be provided with front vehicle wheel, the spider posterior rotation is provided with rear wheel, and the rear wheel axial region is provided with flywheel, and the spider middle and lower part is provided with the transmission fluted disc, transmission fluted disc captive joint pedal is provided with driving chain between flywheel and the transmission fluted disc.This bicycle is owing to be that two wheels contact with the road surface, and stability is not good, particularly when the road surface has lateral inclination to spend, because wheel and road surface friction force are less, slips easily, has potential safety hazard.
The utility model content
The purpose of this utility model is to provide a kind of good stability, preceding bicycle that friction force is bigger.
The technical scheme that realizes the utility model purpose is: the utlity model has spider and the handle that is rotatably connected on the spider front end; Described spider front portion is provided with " worker " font equalizer bar, equalizer bar is made up of upper and lower cross bar and the montant that is hinged on upper and lower cross bar middle part, montant is captiveed joint with the handle lower end, the upper and lower cross bar two ends of equalizer bar respectively are hinged with a fixed cover, a left front wheel carrier of two fixed cover captive joints in upper and lower cross bar left side, a right front wheel carrier of two fixed cover captive joints on upper and lower cross bar right side, left and right front wheel carrier below respectively is provided with left and right front-wheel.
The middle part and the two ends of the upper and lower cross bar of the equalizer bar of bicycle all have shaft-jointed hole before above-mentioned, and the two ends up and down of montant are hinged by pin and upper and lower cross bar middle part respectively; Fixed cover has articulated section and fixed part, and the articulated section of each fixed cover is hinged by a wherein end of pin and cross tube or sheer pole, the fixed part of fixed cover can with the top socket of left and right front wheel carrier, and left and right front wheel carrier is fixing respectively by screw.
The utlity model has following characteristics:
(1) front-wheel of the present utility model is the two-wheel structure, good stability, handle can turn to flexibly by two-wheel synchronization action before the equalizer bar control, solve bicycle dexterously when turn sharp and the car load rollover problem that the back three-wheel brought that has angle of ground, do not influenced the normal use of bicycle.
(2) two front wheel carriers of the present utility model are connected on the equalizer bar, when the road surface has lateral inclination to spend, equalizer bar can be according to two front-wheels and ground-surface contact condition automatic compensation two front wheel carriers, thereby guarantee that two front-wheels contact with the road surface simultaneously, friction force is big, be difficult for slipping, adapt to old man and children especially and use.
(3) the utility model is simple in structure, and is scientific and reasonable, and installation, easy to maintenance has advantages of high practicability.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is an anterior schematic perspective view of the present utility model.
Fig. 2 is portion's schematic perspective view of fixed cover.
Fig. 3 is an overall schematic of the present utility model.
The specific embodiment
(embodiment 1)
See Fig. 1 to Fig. 3, the utlity model has spider 1 and the handle 2 that is rotatably connected on spider 1 front end; Spider 1 front portion is provided with " worker " font equalizer bar 3, equalizer bar 3 is made up of cross tube 31, sheer pole 32 and the montant 33 that is hinged on upper and lower cross bar 31,32 middle parts, the middle part and the two ends of upper and lower cross bar 31,32 all have shaft-jointed hole, and the two ends up and down of montant 33 are realized with upper and lower cross bar 31,32 middle parts hinged by pin respectively; Montant 33 is captiveed joint with handle 2 lower ends, drives equalizer bar 3 and rotate when handle 2 rotates; Upper and lower cross bar 31,32 two ends of equalizer bar 3 respectively are hinged with a fixed cover 4, described fixed cover 4 has articulated section 41 and fixed part 42, the articulated section 41 of each fixed cover 4 is realized with a wherein end of cross tube 31 or sheer pole 32 hinged by pin, the fixed part 42 of fixed cover 4 can with left and right front wheel carrier 6,7 top sockets; Two fixed covers 4 in upper and lower cross bar 31,32 left sides are by the left front wheel carrier 6 of fixed part 42 captive joints, and by screw that left front wheel carrier 6 is fastening; Two fixed covers 4 on upper and lower cross bar 31,32 right sides are by the right front wheel carrier 7 of fixed part 42 captive joints, and by screw that right front wheel carrier 7 is fastening, and left and right front wheel carrier 6,7 belows respectively are provided with left and right front-wheel 8,9.
Front-wheel can guarantee the bicycle three points of contact as the structure of two-wheel when using, good stability, handle can be by two-wheel synchronization action before equalizer bar 3 controls when turning to, turn to flexibly, solve bicycle dexterously when turn sharp and the car load rollover problem that the back three-wheel brought that has angle of ground, do not influenced the normal use of bicycle; Because of left and right front wheel carrier 6,7 is captiveed joint with fixed cover 4, and each fixed cover 4 is pivotallys attached with equalizer bar 3, when there is the lateral inclination degree on the road surface or is uneven, equalizer bar can be according to the high and low position of two front-wheels and the left and right front wheel carrier 6,7 of ground-surface contact condition automatic compensation, thereby guarantee that two front-wheels contact with the road surface simultaneously, increase side-friction force, guarantee cyclist's safety.
