Description

It is a kind of normally with wave variable tricycle

Technical field

The present invention relates to a kind of tricycle, more particularly to it is a kind of normally with wave variable tricycle.

Background technique

Normal tricycle can support oneself, and advantage is in stopping, when starting and going slowly, and car body is steadily safe, therefore especially suitable Cooperation is mobility scooter for old people or special cycle for disabled people.The disadvantage is that when especially suddenly turning round, lack anti-centrifugation ability in fast row, Turning radius overturns with easy greatly.Owner of the tricycle will pass through three measures and improve driving safeties: widen rear wheel away from；Reduce vehicle Speed, speed when especially turning round；Reduce body gravity.

Extension rim is increased away from making the occupy-place of vehicle；Driving benefit can be reduced by lowering speed；Body gravity is reduced by the structure of vehicle With function restriction, the center of gravity range of decrease is limited.

Bicycle is not then just on the contrary, the disadvantage is that be able to support oneself, so lacking stabilization, uncomfortable occlusal equilibration energy when starting and going slowly The elderly, the disabled person of power difference use.But in fast row and quickly turn, human body can be waved with motor vehicles bodies, generated It inside goes all out that centrifugal force can be offset, turning when quickly riding and turning round, flexible, radius is small, high efficiency smooth safety.

For many years, many experts and scholars once or are seeking to design a kind of tricycle in the world, it would be desirable to gram Respectively disadvantage can but have both the two advantage: stable and bicycle the highly effective and safe of supporting oneself of tricycle to both clothes.

The design for waving tricycle in the prior art is numerous, but has the following characteristics that car body can control substantially and shake Pendulum inclination.

For the structure for waving tricycle, can be classified as two classes: 1. full vehicles are waved, i.e., three wheels all wave, only Using chassis as stabilizers, car body is mostly made of link mechanism, and full vehicle can tilt to centrifugal force resistant, to guarantee that car body is steady It is fixed, it needs the strength of materials high, is unlikely to deform, and joint is more, precise structure, processing technology is fine, therefore cost is relatively high.2. Half vehicle waves, i.e., forms front truck rocking section by components such as handlebar, front fork assembly, front-wheel, vehicle seat, vehicle seat column and front frames, by The components such as two rear-wheels and Rear frame form rear car stabilizers, and rocking section front frame axis frame is in stabilizers Rear frame, structure Simply, cheap.

No matter which kind of Rocking cycle type, require to select positive car spring or other elastic components to carry out rigid branch to rocking section Support, strength will arrive by force just to support car body not fall, and vehicle is made integrally to play the steady function of tricycle；When car body is turned When, human body rolls, and requires the strength of spring weak to the rocking section of vehicle can be made to be depressed into inclination by human bady gravitational, and confrontation car body turns Generated centrifugal force when curved makes vehicle integrally play turning of bicycle fast and safely advantage.

No matter which kind of rocker type, have improvement in turning flexibility compared with normal tricycle, but effect is all limited, To find out its cause, the rigid of mainly positive car spring or other elastic components is difficult to appropriately select.When rigidity is too strong, car body is not Be also easy to produce it is enough wave, cannot as normal bicycle complete free inclination, operating difficulties when turn；When rigidity is too weak, If bicyclist's balance is not skilled flexible enough, car body has the danger toppled over, when especially going slowly, need high degree of skill at any time Maintain left-right balance, the case where control is not easy, and varying in weight due to human body, the speed of vehicle and road surface or even wind direction It is changeable, it is all more difficult to determine suitable rigid.

Some inventors are inadequate in order to overcome the problems, such as the positive vehicle dynamics of positive car spring, propose to install additional in rocking section and stabilizers The structure of closing component structure, dual positive vehicle is unavoidably extra, and unlocks rocking section, when playing function of bicycle, but or by positive vehicle bullet The yoke of spring force, freedom degree are inadequate.
