Description

Non-pneumatic tire with high torque performance

Technical Field

The present invention relates to a non-pneumatic tire, and in particular, to a non-pneumatic tire having high torque performance.

Background

The airless tire is a tire which does not rely on air to realize supporting force, does not need inflation and is not afraid of puncture, thereby fundamentally solving the problem of tire burst and saving a large amount of rubber materials. For example, patent application publication No. CN 110091669A: a kind of good non-pneumatic tire of shock attenuation characteristic of buffering, there are wheel webs distributed circumferentially between inner and outer rim in this non-pneumatic tire, the both ends of wheel web connect with the hook structure, this kind of non-pneumatic tire finds in the use test and still has the following disadvantages: after the tire is pressed to deform, the recovery capability is insufficient, and when the tire is impacted by a road surface, the buffering capability is poor, so that the running smoothness of a vehicle is poor; furthermore, when the vehicle is braking or accelerating, the ability to resist the torque of the hub is small, retarding braking and acceleration, and not suitable for high torque vehicles.

Accordingly, there is a need for improvements and optimizations to existing non-pneumatic tires.

The utility model provides a technical scheme that above-mentioned problem adopted is: an airless tire having high torque performance comprising a tire tread vulcanized onto an outer rim, an inner hub connected to the outer rim by circumferentially distributed spokes; the method is characterized in that: the spoke plate comprises a spoke plate main body made of rubber materials, hook structures made of metal sheets are connected to the two ends of the spoke plate main body respectively, and the spoke plate is connected with an inner hub and an outer rim through the hook structures respectively.

Preferably, the hook structure is made of a metal sheet through bending and rubber vulcanization, and one end of the hook structure is connected with the spoke plate main body.

Preferably, the inner hub and the outer rim are both made of engineering plastics, and mounting grooves for mounting the hook structures are formed in the outer side of the inner hub and the inner side of the outer rim.

Preferably, the inner hub is fitted with a rigid support ring for increasing its radial load capacity.

Compared with the prior art, the utility model, have following advantage and effect: the elastic complex body that the wheel radials adopted sheetmetal and rubber combination to make, the radials main part that adopts the rubber material to make can increase buffer capacity, improves the ride comfort and the travelling comfort that the vehicle went, and the crotch structure that adopts the sheetmetal to make has guaranteed the joint strength of wheel radials and interior hub and outer rim, has the fine ability of resisting the wheel hub moment of torsion, makes the braking with accelerate not lags behind.

Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Examples are given.

See fig. 1-3.

The present embodiment discloses an airless tire with high torque performance comprising a tire tread 1, an inner hub 2, a wheel disc 3 and an outer rim 4. The tire tread 1 is a rubber tread that is vulcanized onto the outer rim 4. The inner hub 2 and the outer rim 4 are both made of engineering plastics.

In the embodiment, the inner hub 2 is connected with the outer rim 4 through the spoke plates 3 distributed along the circumferential direction, specifically, the spoke plates 3 comprise spoke plate main bodies 31 made of rubber materials, and hook structures 32 are respectively connected to two ends of the spoke plate main bodies 31; the hook structure 32 is made of a metal sheet (for example, a steel sheet) through bending, one end of the hook structure is connected with the spoke plate main body 31, the end is detachably connected with the spoke plate main body 31 in consideration of subsequent maintenance, the other end of the hook structure 32 is a hook, rubber is vulcanized at the hook, the strength of the hook is improved, and the deformation of the hook can be reduced; the outside of interior wheel hub 2 and the inboard of outer rim 4 all are provided with the mounting groove that is used for installing crotch structure 32, and the cross sectional shape of mounting groove is circular or oval, and spoke plate 3 is connected with interior wheel hub 2 and outer rim 4 respectively through crotch structure 32.
