Abstract

PURPOSE: A pneumatic snow tire for heavy load is provided to improve the snow performance of a tire by promptly discharging snow which is inserted into a tread block after touching the ground. CONSTITUTION: A pneumatic snow tire for heavy load comprises grooves(1), a block(2), and thread(3). The grooves are formed in the columnar direction of a tire. The block is arranged between the grooves and relatively protrudes based on the groove. The block is equipped with snow discharging grooves(4) at a regular interval in the columnar direction of the tire. A compressed air passage slopingly penetrates near the bottom of the snow discharging grooves. The compressed air passage is symmetrically formed in a convex surface(2a) in respect to the center of a snow discharging groove. The tread touches the surface of a road.

Description

중하중용 공기입 스노우 타이어{Pneumatic snow tire for heavy duty}Pneumatic snow tire for heavy duty

본 발명은 중하중용 공기입 스노우 타이어에 관한 것으로, 특히 눈의 배출효과의 개선으로 눈길에서 주행성능이 향상되는 중하중용 공기입 스노우 타이어에 관한 것이다.The present invention relates to a heavy-load pneumatic snow tire, and more particularly to a heavy-load pneumatic snow tire to improve the running performance on the snow road by improving the snow discharge effect.

중하중용 차량에 장착되는 타이어의 트레드에는 노면과 직접 접촉하는 관계로 상품으로의 외관보다 제동력과 구동력 향상, 미끄럼 방지, 승차감 개선 등의 목적으로 그루브(Groove)와 블록(Block)을 설계하고 있는바, 이러한 목적으로 설계되는 중하중용 타이어의 트레드 패턴 형상을 대략 2가지 패턴 형상을 주로 사용하고 있는데, 그 중 한 가지는 타이어의 트레드에 원주방향으로 요철의 홈을 새겨 놓은 리브(Rib)형과, 다른 하나는 블록(Block)들을 배열하여 생기는 러그(Lug)형으로 이루어져 있다.Grooves and blocks are designed for tire treads mounted on heavy-duty vehicles in order to improve braking and driving force, prevent slippage, and improve ride comfort, as they are in direct contact with the road surface. The tread pattern shape of the heavy-duty tires designed for this purpose is mainly used as two types of patterns, one of which is different from the rib type in which the grooves of the unevenness are engraved in the circumferential direction on the tread of the tire. One is composed of lugs formed by arranging blocks.

또한 상기 리브형과 러그형 조합도 개발되고 있으나, 패턴과 러그형 트레드 패턴 양자 모두는 스노우 성능에서 별반 차이를 보이고 있지 않는 것이 사실이다.In addition, although the rib and lug combinations have been developed, it is true that both the pattern and the lug tread pattern show no difference in snow performance.

즉, 눈길 운행시 눈이 상기 트레드의 홈과 블록 사이에 삽입되어서 패턴의 성능을 무력화 시키기 때문이다.In other words, the snow is inserted between the groove and the block of the tread when driving on the snow road to disable the performance of the pattern.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 눈길 운행시 노면의 눈에 접지하는 트레드의 블록 내의 삽입된 눈을 접지 후 배출기능으로 신속하게 배출하여 타이어의 스노우 성능을 향상시킨 중하중용 공기입 스노우 타이어를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the above-mentioned conventional problems, and the snow inserted in the block of the tread to be grounded to the snow of the road surface during the snow road quickly discharged by the discharge function after the ground to improve the snow performance of the tire Its purpose is to provide heavy-duty pneumatic snow tires.

상기와 같은 목적을 달성하기 위한 본 발명은 타이어 원주방향을 따라 여러 개 형성된 그루브와, 상기 그루브들 사이에 배치된 블록들이 형성되어 상기 블록들이 노면에 접지하는 트레드를 구비한 중하중용 공기입 타이어에 있어서, 상기 블록에는 타이어의 원주방향을 따라 등간격으로 눈 배출용 홈이 형성되되, 상기 눈 배출용 홈의 바닥부 부근에는 블록면에 형성된 압축공기통로가 경사진 방향으로 관통되어 있으며, 이 압축공기통로는 블록면에서 눈 배출용 홈을 기준으로 사방으로 여러 개 형성되어 있다.The present invention for achieving the above object is a heavy-duty pneumatic tire having a plurality of grooves formed along the circumferential direction of the tire, and blocks disposed between the grooves are formed to ground the blocks to the road surface In the block, the snow discharge grooves are formed at equal intervals along the circumferential direction of the tire, and the compressed air passage formed on the block surface penetrates in the inclined direction near the bottom of the snow discharge groove. The air passages are formed in various directions from the block surface on the basis of the snow discharge grooves.

이러한 본 발명에 따른 중하중용 공기압 스노우 타이어는 눈길 운행시 블록 내에 형성된 눈 배출용 홈에 쌓인 눈을 압축공기통로들을 통해서 주입된 공기의 유동에 의해 눈을 접지 후에 외부로 신속하게 배출하여 타이어의 스노우 성능을 향상시킨다.The heavy-loaded pneumatic snow tire according to the present invention quickly discharges snow accumulated in the snow discharge groove formed in the block during snow road driving and quickly discharges the snow to the outside by the flow of air injected through the compressed air passages to snow the tire.

이하, 본 발명의 바람직한 실시예를 도면을 참고로 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

도 1은 본 발명이 적용된 중하중용 공기압 스노우 타이어의 트레드 부분을 보여주는 부분 확대 평면도이고, 도 2는 본 발명에 따른 스노우 타이어의 부분 단면도이다.1 is a partially enlarged plan view showing a tread portion of a heavy load pneumatic snow tire to which the present invention is applied, and FIG. 2 is a partial cross-sectional view of a snow tire according to the present invention.

본 발명은 타이어의 원주방향을 따라 여러 개 형성된 오목하게 들어간 그루브(1)와 상기 그루브(1)들 사이에 배치되어 그루브(1)를 기준으로 상대적으로 돌출된 블록(2)들이 형성되고, 상기 블록(2)들이 노면에 접지하는 트레드(3)를 구비한 중하중용 공기입 스노우 타이어에 있어서, 상기 블록(2)에는 타이어의 원주방향을 따라 등간격으로 눈 배출용 홈(4)이 형성되되, 이 눈 배출용 홈(4)의 바닥부(4a) 부근에는 블록면(2a)에 형성된 압축공기통로(5)가 경사진 방향으로 관통되어 있으며, 이 압축공기통로(5)가 블록면(2a)에서 눈 배출용 홈(4)을 센터기준으로 하여 주변에 여러 개 형성되어 있다.The present invention provides a plurality of concave grooves (1) formed along the circumferential direction of the tire and the blocks (2) which are disposed between the grooves (1) and protrude relative to the groove (1), In the heavy-loaded pneumatic snow tire having a tread (3) where the blocks (2) are grounded on the road surface, the block (2) is provided with snow discharge grooves (4) at equal intervals along the circumferential direction of the tire, In the vicinity of the bottom 4a of the snow discharge groove 4, the compressed air passage 5 formed in the block surface 2a penetrates in the inclined direction, and the compressed air passage 5 is the block surface ( In 2a), a plurality of grooves 4 for discharging snow are formed around the center.

상기 블록(2)에 형성된 눈 배출용 홈(4)의 직경(a) 대비 압축공기통로(5)의 직경(b)은 (0.3 ~ 0.5)/a로 되어 있으며, 상기 압축공기통로(5)는 눈 배출용 홈(4)을 센터기준으로 등간격으로 2 ~ 8개가 형성되어 있다.The diameter (b) of the compressed air passage (5) is (0.3 ~ 0.5) / a compared to the diameter (a) of the snow discharge groove (4) formed in the block (2), the compressed air passage (5) The snow discharge grooves (4) are formed at 2 to 8 at equal intervals based on the center.

또한, 상기 압축공기통로(5)의 깊이(h)는 눈 배출용 홈(4)의 깊이(H) 대비 0.8H의 깊이를 갖도록 되어 있다.In addition, the depth h of the compressed air passage 5 is to have a depth of 0.8H compared to the depth H of the snow discharge groove (4).

이 같은 본 발명에 따른 스노우 타이어는 타이어가 노면 접촉시 타이어는 일정 형상의 접지형상을 가지게 되고, 접지 후 노면과 분리되면서 원형상태로 복귀하게 되는데, 이때 타이어의 접지면이 직선에서 곡선으로 하중의 감소로 변하게 된다.In the snow tire according to the present invention, when the tire is in contact with the road surface, the tire has a predetermined shape of grounding, and after grounding, the tire is separated from the road surface and returned to a circular state. It turns into a decrease.

이에 따라 눈이 있는 노면에 타이어의 트레드(3) 접지시 눈이 블록(2)의 눈 배출용 홈(4)에 삽입되어진 후, 블록(2)의 노면 접지가 끝나면 상기 압축공기통로(5)들을 통하여 유입된 공기가 타이어 진행방향으로 탄성에 의해 흐르게 되어 눈 배출용 홈(4)에 끼인 눈을 신속하게 화살표 (B)방향으로 배출하게 된다.Accordingly, when the tread 3 of the tire is grounded on the snowed road, the snow is inserted into the snow discharge groove 4 of the block 2, and when the grounding of the block 2 is finished, the compressed air passage 5 is completed. The air introduced through them flows by the elasticity in the tire traveling direction, so that the snow caught in the eye discharge groove 4 is quickly discharged in the direction of the arrow (B).

따라서 본 발명의 스노우 타이어는 설상에서 신속한 눈 배출기능을 갖는 트레드 구조에 의해 타이어의 스노우 성능이 향상되는 효과를 지닌다.Therefore, the snow tire of the present invention has the effect of improving the snow performance of the tire by the tread structure having a quick snow discharge function on snow.
