Description

Tire with mud and stone discharging structure

Technical Field

The utility model discloses the design has the strengthening rib structure that attaches in the tread groove to sawtooth portion separation and discharge stone, mud piece through its top belong to tire manufacturing technical field.

Background

The existing widely used pneumatic rubber tire can form friction and rolling with the road surface in the rolling running process. Such as through rubble, muddy, or when abominable road conditions such as sand ground, in can the tread pattern piece form the tread pattern groove of clip-in such as little stone, mud piece, especially if can not discharge in time in the earth clip-in tread groove, can block up the tread groove completely, reduce tire grip. For tires with large carrying capacity or off-road vehicles, foreign matters clamped in the pattern blocks generate noise, the braking distance is prolonged at the same time, safe driving is affected, and even the pattern blocks are directly damaged and torn to cause block dropping.

In the prior art, grooves between pattern blocks are connected by reinforcing ribs to improve the rigidity of the pattern blocks and prevent eccentric wear and block falling; also, the bottom of the groove is provided with a plurality of protruding mud discharging strips parallel to the groove, and larger stones are prevented from entering the groove by the elasticity of rubber. However, the existing general reinforcing ribs are usually smooth and convex, only have a reinforcing effect and do not have the functions of removing stones and mud. The traditional mud discharging strips can not effectively discharge stones with the volume similar to that of a groove and mud blocks with the smaller hardness and larger viscosity, and the use defects and the potential safety hazards stated above still exist.

In view of this, the present patent application is specifically proposed.

SUMMERY OF THE UTILITY MODEL

Tire with arrange mud and arrange stone structure lies in solving the problem that above-mentioned prior art exists and pertinence ground has sawtooth portion's strengthening rib in the tread groove design of tire shoulder department, strengthen the tread block rigidity on the basis of tearing resistance ability in order to improve, utilize tire rolling deformation to drive the strengthening rib swing, the sawtooth portion friction through the strengthening rib top surface smashes the foreign matter pine that makes the tread groove mix with and takes off, the centrifugal force that produces is discharged along with the tire rotation at last, thereby reach and get rid of the tread groove foreign matter, protect the tread block, reduce tire operation noise and unbalance, improve the design purpose of braking security performance.

In order to achieve the design purpose, the tire with the mud and stone discharging structure comprises a plurality of groups of pattern blocks arranged on the tread of a body, and concave pattern grooves are formed between the adjacent pattern blocks.

The novel tread pattern block is characterized in that at least a reinforcing rib is arranged in a pattern groove between the same group of pattern blocks, the base part of the reinforcing rib is connected with two adjacent pattern blocks, and a protruded sawtooth part is arranged on the top part of the reinforcing rib.

In the running process of the vehicle, the tire serving as an elastic body is continuously rotated and pressed, and the reinforcing ribs in the grooves are continuously deformed and swing to a certain extent along with the continuous compression deformation of the tire. At this moment, under the effect of rolling of strengthening rib top sawtooth portion, easily appear the crack and break away from each other between mud piece in the insertion tread groove and the strengthening rib, increase friction between the two, then play the effect of the mud piece and the stone of not hard up insertion along with the swing of strengthening rib, finally make mud piece and/or mud piece drop away along with the centrifugal force of the rotatory production of tire.

To further enhance the rolling action and the resultant centrifugal force, the ribs may be arranged in the circumferential direction of the tread.

In order to project and intensively increase the acting force of the sawtooth parts, a refinement and improvement scheme can be adopted, wherein the projecting direction of the sawtooth parts is arranged along the radial direction of the tread.

Further, the preferred design dimensions are (3-30) mm width and (3-20) mm height of the ribs, and correspondingly (0.3-5) mm vertical height of the serrations.

The tire is easy to clamp stones or mud blocks at the tire shoulder from the contact part of the tire and the road surface, in order to improve the capability of removing foreign matters, a plurality of groups of pattern blocks can be symmetrically arranged along the circumferential central line of the tire surface, and the reinforcing ribs are arranged in the pattern grooves between the same group of pattern blocks at the tire shoulder.

In summary, the tire with the mud and stone discharging structure has the following advantages:

1. the rigidity of the pattern block can be effectively improved through the reinforcing ribs, and the tear resistance of the pattern block is improved.

2. Aiming at smaller stones and mud blocks, the reinforcing ribs can be extruded out through deformation and rolling, so that the effect of protecting pattern blocks can be achieved, the braking distance can be shortened, and the driving safety performance of the vehicle can be improved.

3. Foreign matters mixed in can be removed in time, noise and unbalance performance generated when the tire rotates in operation can be reduced, and fuel saving of vehicles and improvement of driving comfort are facilitated.

Detailed Description

Example 1, as shown in fig. 1 to 2, the tire having a mud and stone removing structure described herein is an off-road tire applied to an off-road vehicle, and includes an elastic body and a plurality of sets of blocks 1 on a tread of the body.

For promoting the vehicle in the through performance under the condition of non-pavement road surface or even no way, need deal with promptly such as rubble, mire or sand and so on abominable road conditions, for preventing that the tread decorative block easily leads to tearing, falling the piece phenomenon because of the centre-in of foreign matter such as stone, this application proposes following structural improvement:

along the circumferential central line of the tread, a plurality of groups of pattern blocks 1 are symmetrically arranged, and concave pattern grooves 2 are formed between the adjacent pattern blocks 1;

a rib 3 is arranged in a pattern groove 2 between the same group of pattern blocks 1 at the tire shoulder, the base part of the rib 3 is connected with two adjacent pattern blocks 1, and the top of the rib 3 is provided with a protruded sawtooth part 4;

the reinforcing ribs 3 are arranged along the circumferential direction of the tire tread, the width of each reinforcing rib 3 is 20mm, and the height of each reinforcing rib 3 is 10 mm;

the serrations 4 protrude in the radial direction of the tread and have a vertical height of 1 mm.

As designed above, the reinforcing ribs 3 between two adjacent pattern blocks 1 can enhance the self strength of the pattern blocks, and foreign matters mixed by the reinforcing ribs 3 can be removed in time.

As shown in fig. 3, the dotted line portion in the figure indicates a case where the shoulder portion of the tire does not contact the ground in the no-load state; the solid line portion in the figure shows a state where the tire shoulder is compressively deformed to contact the ground in a loaded state.

In the running process of the vehicle, the tire rotates continuously to contact the ground and generates compression deformation, and the reinforcing ribs 3 synchronously and continuously deform and swing. Due to the swing of the reinforcing ribs 3, cracks are generated between the sandwiched mud or stone blocks and the grooves 2 to be separated. And, the serration 4 on the surface of the reinforcing rib 3 further rolls and rubs to enlarge the gap, thereby playing a role of digging to loosen the foreign matter to be inserted, and finally making the foreign matter fall off with the centrifugal force generated by the rotation of the tire, thereby achieving the purpose of removing the foreign matter in time.

In summary, the embodiments shown in the drawings are only preferred embodiments for achieving the objects of the present invention. Those skilled in the art can now appreciate that other alternative configurations consistent with the present invention may be readily devised. Other structural features thus obtained are also intended to be within the scope of the present invention.
