TH135054B - Rubber bellows bellows - Google Patents

Abstract

Improved wear resistance of the shoulder section. Whereby the efficiency of Prevents sounding without deterioration The contour shape of the tread will be created. With Only one arc In the condition where The thinning rate of the tires is more than 55% and less than 70%, and the internal pressure is 5%. Main groove along the circle That includes Main groove along the circle around the shoulder. And a number of grooves across the shoulder Resting in the area of the rubber shoulder The transverse grooves on the rubber shoulder travel at an angle (formula) 80 to 90 ํ from the side to the outside. Along the axis of the edge in contact with the road surface of the tread With the inner side along the axis of the tire And the inner end along the axis of the tire The axial distance of the tire Ds between the axial inner end of the tire and the main groove along the circle at the tire shoulder ranges from 3.5 to 5.5 mm. Along the roadside, the tire shoulder has the deepest part, where the groove depth is greatest. And the depth of the groove of the deepest part will be 70 to 90% of the depth of the groove. Of the main groove along the circle around the shoulder

Claims (1)

1. A tire bellows with a tire thinner rate of more than 55% and less than 70%, where on the cross-section along the tire meridians. It is mounted on a standard rim and is in condition where the internal pressure is 5%, which is 5% of the internal air pressure. Standards applied There will be contour lines of the surface of the front of the tire. That creates an arc with a radius of With a single curvature, this bellows tire has a main groove along the circle. Located in the front of the tires of it by this groove is included Main groove along the track
