Abstract

The utility model relates to a rear-steering tricycle, which is steered through a rear wheel and driven through front wheels. The rear-steering tricycle comprises a tricycle with two front wheels. One of the front wheels is a driving wheel. A flywheel is fixed on a driving wheel shaft, is driven through a chain by a sprocket, and drives the driving wheel of the front wheels to rotate. The tricycle comprises a single rear wheel with a guide handlebar. A saddle is arranged on a frame, and is matched with the handlebar. The rear-steering tricycle has the advantages that 1, goods can be conveniently looked after in a driving process to be prevented from being lost, so that economic loss is avoided; 2, the tricycle is more flexible when steered at low speed, and is more stable when turning at high speed; 3, the tricycle advances in a pulled way rather than a pushed way, so that the steering shortcomings of drift and the like are overcome, and the phenomena of excessive steering and the like are avoided; and 4, the movement direction of a direction wheel is consistent with the movement direction of center of gravity of the tricycle during the turning of the tricycle, so that the rear-steering tricycle can be more stably driven compared with a front-steering tricycle.

Description

The rear-axle steering three-wheel vehicle
Technical field
The utility model relates to a kind of rear-axle steering three-wheel vehicle that adopts rear-axle steering, f-w-d, belongs to three-wheel vehicle and makes the field.
Background technology
CN101695948A, title " three-wheel vehicle ", comprise vehicle frame and Power Drive Unit, the front portion of vehicle frame is provided with handlebar and front-wheel, and the vehicle frame rear portion is provided with two trailing wheels, be provided with vehicle seat between two trailing wheels, Power Drive Unit comprises Manpower driver and electric powerplant.Its weak point is: container is easily missing package in the back; And wheel flutter is front-wheel, causes turn radius large, and alerting ability is low, and during high speed steering, steering control effort is low.
The utility model content
Design goal: avoid the weak point in the background technology, design a kind of employing rear-axle steering, the rear-axle steering three-wheel vehicle of f-w-d.
Design plan: in order to realize above-mentioned design goal, the utility model is on structure design, the front-wheel of described three-wheel vehicle is Double-wheel structure, front-wheel wherein one is taken turns and is drive wheel, flywheel is fixed on the live axle, and chain drum drives the rotation of front wheel driving driving wheel by the chain drive flywheel and by flywheel, and the trailing wheel of three-wheel vehicle is that single wheel and trailing wheel are equipped with the Guide vehicle handle, vehicle seat is located on the vehicle frame and with handlebar and is complementary, the front-wheel top configuration container of described tricycle frame.It is technical characteristics of the present utility model.The purpose of doing like this is: the wheel flutter of three-wheel vehicle is made as the three-wheel vehicle trailing wheel, when turning to, rotate the Guide vehicle handle on the three-wheel vehicle trailing wheel, can turn to three-wheel vehicle and turn radius little, alerting ability is high, again because the front-wheel of three-wheel vehicle is Double-wheel structure, front-wheel wherein one is taken turns and is drive wheel, so even if turn to, the understeers such as three-wheel vehicle " whipping " also can not occur in the slightly fast situation of speed, the phenomenons such as ovdersteering have increased the control effort that turns to; Container is preposition, can avoid in the three-wheel vehicle driving process, and loss of goods and the driver does not know causes economic loss; The goods on the car front-wheel can be conveniently looked after in simultaneously single driving.
Technical scheme: a kind of rear-axle steering three-wheel vehicle, comprise three-wheel vehicle, the front-wheel of described three-wheel vehicle is Double-wheel structure, front-wheel wherein one is taken turns and is drive wheel, flywheel is fixed on the live axle, chain drum drives the rotation of front wheel driving driving wheel by the chain drive flywheel and by flywheel, and the trailing wheel of three-wheel vehicle is that single wheel and trailing wheel are equipped with the Guide vehicle handle, and vehicle seat is located on the vehicle frame and with handlebar and is complementary.
The utility model is compared with background technology, and the one, conveniently in the process of travelling, look after goods, avoid loss of goods, economic loss; The 2nd, three-wheel vehicle low speed rotation to the time more flexible, cross at a high speed when curved more stable; The 3rd, advance rather than pushed away and advance because vehicle is tension, so the understeer such as whipping, the phenomenons such as ovdersteering can not occur; The 4th, when car turned round, the gravity motion direction of the sense of motion of steering wheel and three-wheel vehicle was consistent, thus than the three-wheel vehicle of front-wheel steering compare travel more steady.
Description of drawings
Fig. 1 is the structural representation of rear-axle steering three-wheel vehicle.
Fig. 2 is handle bar structure one birds-eye view.
Fig. 3 is handle bar structure two birds-eye vieies.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1-3.A kind of rear-axle steering three-wheel vehicle, comprise three-wheel vehicle, the front-wheel 3 of described three-wheel vehicle is Double-wheel structure, front-wheel 3 wherein one is taken turns and is drive wheel, flywheel is fixed on the live axle, chain drum 5 drives flywheel and drives front-wheel 3 drive wheels by flywheel by chain 6 and rotates, and the trailing wheel 4 of three-wheel vehicle is for single wheel and trailing wheel 4 are equipped with Guide vehicle 7, and vehicle seat 8 is located on the vehicle frame 1 and with handlebar 7 and is complementary.Described handlebar 7 lays respectively at vehicle seat 8 both sides for two handles of the symmetrical handlebar of U-shaped and U-shaped handlebar, or handlebar 7 is monolateral handlebar and is positioned at vehicle seat 8 one sides.The front-wheel 3 tops configuration container 2 of described tricycle frame 1.Its manufacture craft is prior art, is not described herein at this.
What need to understand is: although above-described embodiment is to the mentality of designing of the present utility model simple text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
