Abstract
A steering wheel rear wheel turning tricycle is provided, which comprises a front wheel and two real wheels, with wide chair at the middle. The front wheel is the driving wheel, aided by human foot pedal or electric force, and the pedal chain wheel is close to the front wheel; the two real wheels control the steering through the steering mechanism pulled by a steering wheel steel wire; the steering mechanism is steered by the steel wire pulled by the steering wheel and umbrella gear wheel.
Description
1. affiliated technical field
The utility model relates to a kind of steering wheel type rear-axle steering tricycle, belongs to the light-duty vehicle.
2. background technology
Though present known two-wheeled cycle has light labour-saving advantage, being limited to is two wheel constructions, and the poor stability of riding, the inconvenience of getting on or off the bus have to servant's Parkings, especially is not suitable for the elderly and uses; The crowded bicycle recoverable amount of China's urban highway ranks first in the world in addition, thereby the two-wheel car poor stability is conspicuous on crowded urban highway.Seeing that more present visitor uses tricycle, is to improve from box goods three-wheel basically.Obvious shortcoming is that seat height, vehicle body are long, center of gravity higher partially before, the vehicle body volume is big.In addition, above-mentioned two class vehicles still have common shortcoming to be owing to adopt all that cross handle formula front-wheel steering design, the preceding formula of bowing are ridden, too small cushion in addition, very easily cause the fatigue of the person's of riding wrist, waist and buttocks.
3. summary of the invention
The defective the technical solution adopted in the utility model that exists at prior art is: one, on overall structure, still adopt positive three-wheel layout, front-wheel with manpower foot-operated or motor power-assist, (it is long that the seat height is lower than general adult's leg to establish wide chair type seat, and the adjustment before and after can doing up and down), back two-wheeled turns to, and controls with bearing circle to turn to (bearing circle can also be done the adjustment of front and back up and down); They are two years old, adopt steering wheel type steel wire traction steering hardware, its principle of work is: steering wheel shaft connects a bevel gear to be paid, and wherein fixes a drag-line disk on the large bevel gear, one wire digging line twines on it, and wire digging line is connected on the rear-axle steering joint by the vehicle frame tube cavity with bifilar.Thereby driving the wire digging line pulling trailing wheel that moves reciprocatingly when the positive and negative rotation of drag-line disk realizes turning to; Its three because front-wheel do not do and turn to, so drive sprocket can be close to the front-wheel setting or be set directly on the front wheel spindle, thereby shortens body dimensions greatly.The beneficial effect of this utility model is: the compact conformation HOP ON; Good stability, the servant is not stopped; Convenient for control, need not possess the technology of riding two-wheel car; Sitting posture is driven, and comfortablely (is similar to and drives a car) safely; The turning of rear-axle steering half makes turning more flexible through less; Available manpower is ridden, also available electric boosted (its advantage is more obvious when as battery-driven car).
4. description of drawings
Fig. 1 is the overall structure front view, and Fig. 2 is a direction machine constructional drawing, and Fig. 3 is a rear-axle steering mechanism birds-eye view.Among the figure: (1) direction machine, (2) front-wheel, (3) foot-operated sprocket wheel, (4) vehicle frame, (5) rear-axle steering joint (6) trailing wheel, (7) seat assembly, (1.1) axis of orientation, (1.2) guy anchor, (1.3) large bevel gear, (1.4) driving gear, (8), front fork tube (9) wire digging line, (10) front fork gusset plate guide wheel, (11) vehicle frame bottom girder pipe, (12) back axle drag-line guide wheel, (13) steering swivel transverse arm, (14) trailing wheel disc brake.
5. the specific embodiment
Front-wheel (2) is fixed in vehicle frame (4) front end, drives (sprocket wheel is near the front-wheel setting) by foot-operated sprocket wheel (3); Two trailing wheels (6) are positioned at vehicle frame (1) rear portion, are installed on the steering swivel (5); Axis of orientation (1.1) is gone up fixed installation driving gear (1.4) in direction machine (1), fix a guy anchor (1.2) on the large bevel gear (1.3), wire digging line (8) is fixed with any on guy anchor and in the lower end of dish, then from middle bifilar the passing of front fork tube (9), be connected on the steering swivel transverse arm (13) after vehicle frame bottom girder pipe (11) passes through back axle drag-line guide wheel (12) commutation again through passing again after front fork gusset plate guide wheel (10) commutation, when wire digging line is realized rear-axle steering during forward and reverse rotation under the drive of bevel gear pair.
Claims (2)
1. steering wheel type rear-axle steering tricycle is characterized in that: preposition one takes turns, rearmounted two-wheeled, and the foot-operated or driven by power with manpower, front-wheel is a drive wheel, and foot-operated sprocket wheel is near the front-wheel setting, and trailing wheel is that wheel flutter is realized turning to by steel wire traction with bearing circle.
2. according to the described steering wheel type rear-axle steering of claim 1. tricycle, it is characterized in that: steering wheel shaft connects a bevel gear pair, wherein fix a guy anchor on the large bevel gear, twine a wire digging line on the dish, be fixed in the guy anchor bottom with a bit, wire digging line is connected to the rear-axle steering joint after inner bifilar the passing in direction machine front fork tube inside, vehicle frame bottom girder pipe and turns on the transverse arm, realizes rear-axle steering.
