Embodiment Construction

[0016] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0017] As shown in the figure, a tire with controllable friction force in this embodiment includes a tire body 1, and is characterized in that: it also includes an anti-skid structure fixed on the tire body 1, which includes an anti-skid layer 2 and a variable magnetic field, and the anti-skid layer 2 is the magnetorheological rubber fixed on the tire tread in a full circle. In order to ensure the properties of the tire itself, along the width of the tire, the width of the magnetorheological rubber is consistent with the tread width and is closely attached to the tire tread. At the same time, To adapt to the fit with the tread, on the circumference, the anti-skid layer...

Abstract

The invention discloses a frictional-force-controllable tyre, and belongs to the technical field of tyres. The frictional-force-controllable tyre comprises a tyre body and further comprises an anti-slipping structure fixed to the tyre body. The anti-slipping structure comprises an anti-slipping layer and a variable magnetic field capable of generating magnetic action on the anti-slipping layer. The anti-slipping layer is magneto-rheological rubber which is fixed on the tread of the tyre in a whole-circle mode or spaced-arc mode. The magneto-rheological rubber is arranged on the tread of the tyre, under the action of the magnetic field, the magneto-rheological effect is generated by the magneto-rheological rubber, then the friction coefficient of the surface of the tyre is changed, and the frictional force between the tyre and a contact object is adjustable; therefore, the adhesive force level is improved, and the slipping problem of the tyre can be solved in the true sense.

Description

technical field [0001] The invention belongs to the technical field of tires and relates to a tire with controllable frictional force. Background technique [0002] When an airplane takes off and lands, a car starts, or accelerates on a slippery or icy road, skidding is prone to occur, which may cause increased fuel consumption in the slightest and cause serious traffic accidents in the severest case. The tire slips because the car engine transmits the driving force to the wheel, and the friction between the tire and the road surface cannot provide enough reaction force for the driving wheel. Simply put, the friction coefficient between the road surface and the tire is not enough. When the driving force transmitted to the wheel exceeds the maximum static friction force, the wheel will slip and spin. There are many ways to prevent the driving wheel from skidding, such as installing anti-skid chains, using anti-skid snow tires and anti-skid tires with anti-skid studs, and ado...
