Description

A kind of normal with wave variable tricycle

Technical field

The present invention relates to a kind of tricycle, particularly relate to a kind of normal and wave variable tricycle.

Background technology

Normal tricycle can be supported oneself, and advantage is when stopping, starting and go slowly, and therefore the steady safety of car body be particularly suitable as mobility scooter for old people or special cycle for disabled people. Shortcoming is at fast row, and when particularly suddenly turning round, the anti-centrifugal ability of shortage, turning radius overturns with easy greatly. Tricycle improves driving safeties mainly through three measures: widen rear wheel from; Reduce speed, speed when particularly turning round; Reduce body gravity.

Extension rim strengthens from the occupy-place making car; Lower speed and can reduce driving benefit; Reduction body gravity is limited with function by the structure of car, and the center of gravity range of decrease is limited.

Then just on the contrary, shortcoming is not to be able to support oneself to bicycle, so lack stable when starting and going slowly, is not suitable for the old people of balanced capacity difference, people with disability's use. But at fast row with when quickly turning round, human body can wave by band motor vehicles bodies, goes all out to offset centrifugal force in produced, turn when quickly riding and turning round flexibly, radius little, high efficiency smooth safety.

For many years, a lot of experts and scholars once or seek to design a kind of tricycle in the world, it would be desirable to each shortcoming but can both's advantage to overcome the two: stable and bicycle the highly effective and safe of supporting oneself of tricycle.

The design waving tricycle in prior art is numerous, but substantially has the following characteristics that car body can be vacillated now to the left, now to the right inclination.

Just wave the structure of tricycle, it is possible to be classified as two classes: 1. full car waves, and namely three wheels all wave, only with chassis for stabilizers, car body is many to be made up of bar linkage structure, and full car can tilt to centrifugal force resistant, for ensureing that car body is stable, need the strength of materials high, it is unlikely to deform, and joint is many, precise structure, process technology is fine, and therefore cost is higher. 2. half car waves, namely being formed front truck wag by parts such as handlebar, front fork assembly, front-wheel, vehicle seat, vehicle seat column and front frame, two parts such as trailing wheel and Rear frame form rear car stabilizers, wag front frame axle frame is in stabilizers Rear frame, simple structure, cheap.

No matter which kind of Rocking cycle type, is required for selecting positive car spring or other elastic components that wag is carried out rigid support, and its strength just to arrive by force and can support car body and do not fall, and makes car entirety play the steady function of tricycle; When car body is turned, human body rolls, and requires that again the strength of spring is weak and is depressed into inclination, produced centrifugal force when antagonism car body is turned to the wag that can make car by human bady gravitational, makes car entirety play turning of bicycle advantage fast and safely.

No matter which kind of rocker type, has improvement compared with normal tricycle in turning motility, but effect is all limited, traces it to its cause, and mainly the rigid of positive car spring or other elastic components is difficult to appropriate selection. When rigidity is too strong, car body is not likely to produce enough waving, it is impossible to complete free inclination as normal bicycle, operating difficulties when turning round; When rigidity is too weak, if bicyclist's balance is skilled not flexibly, car body has the danger toppled at any time, when especially going slowly, it is necessary to high degree of skill maintains left-right balance, control not easily, and due to varying in weight of human body, the speed of car and the situation on road surface, even wind direction is changeable, is all more difficult to determine suitable rigid.

Some inventor is in order to overcome the problem that positive car spring positive car dynamics is inadequate, it is proposed to installing closing component structure additional in wag and stabilizers, the structure of dual positive car is unavoidably unnecessary, and unlock wag, when playing function of bicycle, but still by the yoke of positive car spring elastic force, degree of freedom is inadequate.
