Description
Technical field: the utility model relates to bicycle, particularly turn to bicycle behind the before driving.
Background technology: in life at present, bicycle remains a kind of basic walking-replacing tool that can not lack, though bicycle is of a great variety, wherein: the bicycle of before driving is a kind of improvement to existing bicycle, a kind of wushu before driving bicycle is disclosed as Chinese patent 98240861.7, this car is provided with anodontia flywheel on front-wheel, and at handlebar, be provided with driver train between standpipe and the anodontia flywheel, bearing fit swing handlebar acting by control axle sleeve of the handle in the drive part and dead axle, and, drive function before and after having by the rotation of the anodontia flywheel driving of connections such as the cable wire in running part front-wheel.Chinese patent ZL02207513.5 discloses an a kind of parallel before driving bicycle that moves, above-mentioned two kinds of before driving bicycles, and the car body overall appearance does not have big change than standard bicycle, but actuating device hangs the outward appearance that influences the car body brevity and lucidity outward.Chinese patent ZL90224399.3 provides a kind of portable before driving bicycle, driver train is arranged on the front-wheel, trailing wheel is a wheel flutter, seat board drops on " V " type vehicle frame, turn to transmission mechanism to be arranged in the steel pipe of " V " type vehicle frame, drop center wheel by wherein and transmit parts such as rope can make the rotation of handlebar control to turning to of trailing wheel.
Summary of the invention: the purpose of this utility model turns to bicycle after providing a kind of novel before driving.
The technical solution of the utility model turns to bicycle to comprise vehicle frame, drive system, steering swivel system after being achieved in that before driving.Vehicle frame constitutes " △ " shape by preceding cant beam, back cant beam, crossbeam, and vehicle seat is in " △ " shape vehicle frame upper end, and the crossbeam connection turns to standpipe, turns to the standpipe upper end to connect handlebar.Drive system is arranged between front-wheel axle center and the front vehicle frame, and front-wheel is a bull wheel, and trailing wheel is a steamboat; Steering swivel system is made up of handlebar, connecting rod, universal-joint, quadrant gear, trailing wheel, plus-minus screw, and steering swivel system is contained in and turns in standpipe and the crossbeam, is connected by connecting rod between handlebar, universal-joint, quadrant gear, the trailing wheel.Connect handlebar and universal-joint by connecting rod, universal-joint connects quadrant gear by connecting rod, by another sector crop rotation opposite sense rotation, pass to trailing wheel by connecting rod again, turn to after the realization, on the connecting rod at steering swivel system two ends plus-minus screw is arranged, be used to adjust the length of steering swivel system two end links.
Beneficial effect:
The utility model has changed the styling design of standard bicycle, the design of " △ " shape vehicle frame makes this car omit the space of front fork and handlebar junction, drive system is arranged between front-wheel axle center and the front vehicle frame, the car weight heart is moved forward, direction is close to the drive wheel axle center, strengthen front-wheel and ground-surface pressure, the front-wheel enlarged diameter prolongs its autobiography girth.Because of this car is a before driving, front-wheel need not turn to, and steering swivel system is hidden in and turns in standpipe and the crossbeam, does not influence the car body outward appearance, and big steamboat reasonable combination makes the vehicle overall appearance succinct, and speed is fast, turns to flexibly good stability; Car body is light, volume is little, saving in material.
Description of drawings:
Fig. 1 is the utility model integral structure scheme drawing;
Fig. 2 turns to the system architecture scheme drawing in the utility model.
1 handlebar, 2 turns to standpipe, 3 preceding cant beams, 4 vehicle seats, 5 back cant beams, 6 inspection sockets, 7 back vents, 8 front-wheels, 9 trailing wheels, 10 flywheels, 11 chains, 12 cranks, 13 wheel discs, 14 steering swivel systems, 15 crossbeams, 16 universal-joints, 17,18,19 connecting rods, 20,21 quadrant gears, 22,23,24 plus-minus screws among the figure
The specific embodiment:
Shown in Fig. 1 structure, vehicle frame is made up of handlebar 1, preceding cant beam 3, vehicle seat 4, back cant beam 5, crossbeam 15, and front-wheel 8 is designed to bull wheel, and trailing wheel 9 is designed to steamboat, the preceding cant beam 3 of vehicle frame, back cant beam 5, crossbeam 15 constitute " △ " shape vehicle frame, and vehicle seat 4 is in " △ " shape vehicle frame upper end.Crossbeam 15 front ends are the car fork, turn to standpipe 2 upper ends to connect handlebar 1, and the lower end is connected with crossbeam front vehicle fork junction at crossbeam 15, the front vehicle fork of cant beam 3 is middle in the past passes.Drive system is made up of front-wheel 8, flywheel 10, chain 11, crank 12, wheel disc 13, is arranged between front-wheel 8 axle center and the front vehicle frame.Steering swivel system 14 is by handlebar 1, connecting rod 17,18,19, and universal-joint 16, quadrant gear 20,21, trailing wheel 9, plus-minus screw 22,23 is formed, and is contained in to turn in standpipe 2 and the crossbeam 15.Handlebar 1 connects universal-joint 16 by connecting rod 17, and universal-joint 16 connects quadrant gear 20, quadrant gear 20 interlock quadrant gears 21 by connecting rod 18, quadrant gear 21 connects trailing wheel 9 by connecting rod 19, quadrant gear 21 is done opposite spin, and quadrant gear 21 connects trailing wheel 9 by connecting rod 19, consults Fig. 2.For making things convenient for the inspection and maintenance steering swivel system, turning to standpipe 2 and crossbeam 15, crossbeam 15 inspection socket 6 to be arranged, be used for the inspection and maintenance of steering swivel system 14 with the junction of back cant beam 5, the lid sealing is arranged on the inspection socket 2.Plus-minus screw 22 is used for adjusting the length of connecting rod 17, and plus-minus screw 23 is the length that is used for adjusting connecting rod 19.
