Description

Double-drive quadricycle

The utility model be a kind of by two ordinary bicycles with two sedan-type cycles that drive that the manipulation adaptor union is formed in parallel, the interlock braking mechanism is housed simultaneously, rainproof compartment or wanigan.This pair drives sedan-type cycle, except that relying on manpower to be stepped on the driving with pedal, also can adorn spark ignition engine or storage battery and drive.For lovers or general family provide a kind of vehicle that replace existing bicycle and serve many purposes.

Disclosing a kind of bicycle among the patent documentation CN86108099, is to be composed in series by two bicycles, this car weight heart instability, and it is dumb to turn, and driving safety is poor, and the bicyclist gets anteroposterior position, the inconvenience talk, being obstructed in a bicyclist visual field, position, back, lacks temperament and interest.

The purpose of this utility model provide a kind of by simple parts with two sedan-type cycles that drive that two ordinary bicycles compose in parallel, solve the brake problem that turns to synchronously and link when parallel connection is ridden, improve stability and safety, increase bicyclist's interest.

Technical solution of the present utility model is, by coupling mechanism with two bicycles and join together, this mechanism comprises the link span combination that connects two bicycle front fork sleeve pipes, the pipe link and the pipe link that is connected two bicycle rear axles and vehicle seat axle that connect two back fork of bicycle connect back two car longitudinal axis keeping parallelisms; Between two bicycle handle bar's axles, there is an interlock effector that two bicycle front-wheels are turned to synchronously that nose wheel steering is kept synchronously; The interlock braking mechanism that has control two bicycle rear brake rubbers to be synchronized with the movement is realized the synchro control of rear wheel brake.

The utility model is handled and the synchronous brake problem after having solved two car parallel connections synchronously, compares with tandem type, has steadily of centre of gravity, riding safety, and the visual field is broad, broad-spectrum advantage, easy accessibility still recovers the ordinary bicycle function after the decomposition simultaneously.

The embodiment that draws below in conjunction with accompanying drawing describes structure of the present utility model and using method in detail.

Fig. 1 is this utility model scheme drawing.Fig. 2 is that Figure 1A is to view.Fig. 3 is that the B of Fig. 1 is to view.Fig. 4 is interlock braking mechanism scheme drawing.

Front fork sleeve referring to Fig. 1,2,3, two bicycles (1), (2) is connected by link span.The link span combination is made up of connection support (10), clamping plate (26), (27), screw (25), connecting support (10) is platy structure, its width has the dead slot of expendable weight than the little And of length of front fork sleeve, support (10) one ends have a recessed arc groove, and inside radius and front fork sleeve external diameter adapt, and the other end has two recessed arc grooves, one of them groove inside radius and front fork sleeve external diameter adapt to, and another and handlebar axis external diameter adapt.A corresponding groove is arranged on the clamping plate (27), two corresponding grooves are arranged on the clamping plate (26), when mounted, earlier the handlebar of right car is unloaded, load onto in situ one not with handlebar axis, groove on support (10), clamping plate (26), (27) is clamped two front fork sleeves and the right car handlebar axis that unloaded respectively, with 8 screws (25) support (10) and clamping plate (26), (27) is tightened up, and two car front ends are coupled together.Right handlebar was fixed on and connected on the support (10) and can not rotate this moment, only played the handrail effect.Pipe link (3) can be lath or socket, and its two ends are fixed by a screw side relative with two bicycle back forks.The member that pipe link (4) is made up of rod member, two vertical rods, two horizon bars and a cross bar are arranged, the lower end of vertical rod is fixed on the car rear axle, and the front end of horizon bar and vehicle seat axle are fixed, and the cross bar two ends are fixed with vertical rod and horizon bar respectively.

The linked effector control of sedan-type cycle two front-wheels realizes rotating synchronously.Referring to Fig. 3, the interlock effector by the interlock joystick (7), with handlebar axis (9), beat bar (12), movable pin (11) and clamp-screw (13) do not form, beat bar (12) one ends have inner hole sleeve and tighten up by screw (13) and handlebar axis on handlebar axis, and the other end is connected with interlock joystick (7) sliding fit by pin (11).As seen from the figure, two handlebar axis centers and two pins (11) are centered close to four summits of a parallelogram, when rotating left handlebar, drive the beat bar (12) that is attached thereto and rotate, promptly drive right wheel by interlock joystick (7) and another beat bar (12) and rotate synchronously.

The interlock braking mechanism is seen Fig. 4, this mechanism is braked (6) by interlock, pin (24), synchronous brake bar (22), clamp-screw (23), the brake rubber (17) of pin (21) and former bicycle, (19), brake connecting rod (15), (20) form, the interlock brake is (6) bar that band circular arc is turned round, at the position of turning round pin-and-hole is arranged, pin (24) passes the brake that will link of this hole (6) is installed in two brakes installing between the clamping plate (14), clamping plate (14) are fixed on the middle part that connects support (10), can weld also available screw and connect.Synchronous brake bar (22) is heel piece shape or tubulose stock, and two ends are fixing by clamp-screw (23) and brake connecting rod (20), and the middle part is connected the termination that (6) are positioned at the below with the interlock brake by pin (21).When pushing the brake handle termination of (6) that is positioned at the top downwards, brake is rotated (6) around pin (24), tractive synchronous brake bar (22) travels forward brake rubber (17), (19) by brake connecting rod (20) forward, checks two trailing wheels (16), (18).

The utility model makes two from row car And connection, when riding by left position cyclist's controlling party to, two people drive simultaneously, good stability when static can install rainproof compartment or wanigan easily additional, to enlarge the scope of application.
