Description
Technical field
The present invention is a kind of vehicle running device, belongs to vehicle to run technical field, the present invention is proposed based on retainer
Deformation, the rotation of crawler belt ring, can be achieved wheeled state and the Athey wheel of crawler type State Transferring, which not only has
The wheeled efficient feature run at high speed, and possess the characteristics of crawler travel cross-country traveling ability, thus be conducive to have given play to it is wheeled or
Caterpillar advantage, enables the traveling high speed of vehicle to be taken into account with cross-country traveling ability.
Background technology
In the history that vehicle to run component continues to develop, wheel becomes two kinds of main sides of vehicle to run with crawler belt
Formula, i.e., wheeled and crawler type.But both walking manners respectively have advantage and disadvantage.
The use of wheel is away from the history for having 6,000 years today, although the invention time neither one of wheel is clearly recorded,
But it can see the wheel on battlebus in the ancient times picture of B.C. 3200.Can certainly be before more than 3,000 years
The use of visible wheel in the pictograph of " car ".The development of wheel technology accelerates the paces of human society advance.From automobile
To armored vehicle, wheel becomes the main ground-engaging element of ground vehicle.
The major advantage of wheel is：Since wheel and ground are contacted in point type or wire type, its steering moment and friction
Coefficient is smaller；Due to being rolling friction between circular wheel and ground, its traveling power consumption is smaller.
The major defect of wheel is：Since wheel and ground are contacted in point type or wire type, the earth-catching property of wheel is poor,
Do not possess anti-depression ability；Since the mistake vertical wall ability of circular wheel is directly proportional to wheel footpath size, its cross-country power by
To the limitation of wheel body limit height.Though wheel diameter can be expanded to two meter five or so with regard to existing process technology, its is huge
The problem of wheel body has but tied up excessive vehicle body space, bigger is that the wheel of two meter five of a diameter, the car body shared by it has
It is huge to imitate space, and the steering space needed for it even more detracts the useful space of car body significantly, with the increasing of wheel footpath, car
The weight of wheel itself can also increase, and the several shortcomings of the above, directly limit the practicality of large diameter wheel.

Scraping phenomenon is produced, steering moment is increased suddenly.Caterpillar in the process of moving, the rough muscle of crawler belt itself
Bar, and the shoe mutually scraped admittedly with effect with rotating tape guide are perverse, all inevitably because sliding friction adds crawler belt
In-fighting power；The second is travel speed is low.When crawler unit in hard flat road surface at a relatively high speed when driving, for anti-depression
And the area that contacts to earth increased, the even more main source into running resistance, into the work(for restricting crawler unit raising speed
Consumption burden；The third is component wear is big, noise is big, and use cost is high, and supply ensures that difficulty is big.
It is wheeled with caterpillar advantage in order to balance, carry out numerous studies both at home and abroad in recent years, it was also proposed that various sides
Case, the Athey wheel announced are not suitable for heavily loaded operating mode often appropriate only to the operating mode of underloading.Athey wheel proposed by the present invention
Light duty is applicable not only to, and is suitable for severe duty.One kind proposed by the present invention can realize wheeled or crawler type two
