본 고안은 단층트레드 공기압 타이어, 더욱 상세히는 버스, 트럭과 같은 중하중용 타이어의 트레드부(tread부)그루브(groove)의 깊이가 단면상의 중앙부에서 양측방향으로 감소되며 단층을 이루도록 하여서된 단층트레드 공기압 타이어에 관한 것이다.The present invention is designed to reduce the depth of tread grooves of single-tread pneumatic tires, and more specifically, heavy-duty tires such as buses and trucks, to reduce the width of the tread grooves in both directions at the center of the cross-section. It's about tires.

종래의 일반적인 중하중용 타이어(T1)는 제1a도에서와 같이 트레드부(1')에서 깊이 14.0㎜-17.5㎜의 그루브(2)를 형성시킨 것이 사용되고 있다.The conventional general heavy-duty tire T 1 is formed by forming a groove 2 having a depth of 14.0 mm to 17.5 mm in the tread portion 1 ′ as shown in FIG. 1A.

이러한 일반타이어(T1)의 주행거리를 증가시킬수 있도록 근래에 제안된 딥트레드 타이어(deep tread tire : T2)는 제1b도에서와 같이 트레드부(1")에 깊이 21.0㎜정도의 그루브(2")를 형성시킨 것이 주로 구동축용으로 사용되고 있다.In order to increase the mileage of the general tire (T 1 ), a deep tread tire (T 2 ) recently proposed has a groove having a depth of about 21.0 mm on the tread portion 1 ″ as shown in FIG. 2 ") is mainly used for a drive shaft.

도면중 미설명부호(3)은 보강벨트이고, t1, t2는 숄더부(shoulder)두께이다.In the figure, reference numeral 3 is a reinforcing belt, and t 1 , t 2 are shoulder thicknesses.

딥트레드타이어(T2)는 그루브(2")의 깊이가 증가함에 따라 고무량의 증가를 초래하여 숄더부에 두께 t2가 일반 타이어(T1)의 숄더부두게 t1보다 그루브(2")의 깊이증가에 해당하는 값만큼 두꺼워지게 된다.Deep-tread tires (T 2) has a groove (2 ") of the depth is increased and that the results in an increase in Flat thickness t 2 to the shoulder portion than the shoulder pier to t 1 of the general Thai (T 1) grooves (2, as" ) Will be thickened by the value corresponding to the depth increase.

그러나 숄더부의 두께증가는 결국 발열증가와 방열감소를 초래하게 되어 벨트(3")가장자리부에서의 세퍼레이션(separation)유발우려가 현저히 높아지므로 고속주행용으로 사용하기에는 부적합한 문제점이 있다.However, an increase in the thickness of the shoulder part causes heat generation and heat dissipation decrease, resulting in an increase in separation incidence at the edge of the belt 3 ″, which is not suitable for use for high-speed driving.

본 고안은 이러한 문제점을 감안하여 딥트레드라이어에서의 세퍼레이션 현상을 배제시키고 차량선회시의 복원토오크를 향상시켜 주행시의 안정감을 얻을수 있으면서도 딥트레드타이어의 주행거리 향상 효과를 유지할수 있게된 단층트레드 공기압 타이어를 제공하기 위한 목적을 갖는다.In consideration of these problems, the present invention eliminates the separation phenomenon in the deep-treat dryer and improves the restoration torque during the turning of the vehicle to obtain a sense of stability while driving, while maintaining the effect of improving the mileage of the deep tread tire. Has a purpose to provide a tire.

이하에서 본 고안의 바람직한 실시예를 첨부된 도면에 의해 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail by the accompanying drawings.

본 고안은 단층트레드 공기압타이어(T)는 제2도에서와 같이 회전측과 래디알 방향의 대칭축이 이루는 평단면의 트레드부(1)상에서 1개 이상의 리부(rib : 1A)가 1.0㎜이상의 단을 이루되, 그루브(2)의 깊이가 20㎜-26㎜이며, 중앙부에서 양측방향으로 갈수록 감소되게 형성하여서 된 것이다.The single layer tread pneumatic tire (T) is one or more ribs (1A) of 1.0 mm or more on the tread portion (1) of the flat cross section formed by the axis of symmetry of the rotational side and the radial direction as shown in FIG. The groove 2 has a depth of 20 mm to 26 mm, and is formed to decrease in both directions from the center portion.

이와같이 구성된 본 고안 타이어(T)는 그루브(2)의 깊이가 증가함에 따라 두께가 증가된 r만큼 증가된 주행거리를 나타내게 되고, 반면에 숄더부의 두께 t는 딥트레드타이어(T2)보다 얇은 보통 타이어(T1)의 수준을 유지하게 됨으로써 세퍼레이션 현상배제에 의한 고속주행성의 향상을 도모하게 된다.The tire T of the present invention configured as described above exhibits a mileage increased by r whose thickness increases as the depth of the groove 2 increases, whereas the thickness t of the shoulder part is thinner than that of the deep tread tire T 2 . By maintaining the level of the tire T 1 , it is possible to improve the high-speed running performance by the separation developer removal.

또한, 본고안 타이어(T)의 선회시 복원토오크는 일반 타이어(T1) 또는 딥트레드타이어(T2)의 복원토오크보다 월등히 큰값으로 발생되어 특히 전륜타이어로서의 요구특성을 최대한 충족시키게 된다.In addition, the recovery torque at the time of turning the tire T is generated to be much larger than the recovery torque of the general tire T 1 or the deep tread tire T 2 , so as to meet the required characteristics as a front wheel tire to the maximum.

제3도는 이러한 복원토오크 발생을 역학적으로 설명한 것으로 제3a도, 제3b도에서는 차량이 선회할때 타이어에 작용하는 힘(cornering force)과, 그에 따른 타이어의 변형상태를 도시하였다.FIG. 3 is a dynamic explanation of the restoration torque generation. FIGS. 3a and 3b illustrate a force acting on the tire when the vehicle turns and a deformation state of the tire.

제3c도에서는 동일한 하중과 동일한 코너 선회력이 작용할 경우 나타나는 측력(lateral force)분포를 도시한 것으로 L1은 보통 타이어(T1) 또는 딥트레드타이어(T2)의 접지길이이고 L2는 본 고안 단층트레드 타이어(T)의 접지길이를 나타내며, F는 코너선회력과 측력의 합력을 나타낸다.Figure 3c shows the lateral force distribution that occurs when the same load and the same corner turning force is applied, L 1 is usually the ground length of the tire (T 1 ) or deep tread tire (T 2 ) and L 2 is the present invention The grounding length of the single-layer tread tire T is shown, and F represents the combined force of the corner turning force and the side force.

여기에서 알수 있듯이 본 고안 타이어(T)는 접지길이 차이에 의한 합력의 작용점이 종래 타이어(T1, T2)보다 ΔT만큼의 차이가 발생하여 결국 ΔT·F만큼 증가된 복원토오크를 나타내게 되는 것이다.As can be seen from the tire T of the present invention, the point of action of the force due to the difference in the ground length is different from the conventional tires T 1 and T 2 by ΔT, and thus the restoration torque is increased by ΔT · F. .

제4도에서는 본 고안의 변형실시예들을 도시한 것으로, 본 고안의 구성요구 조건을 벗어나지 않는 범위 내에서 도시된 이외의 다양한 변형이 실시되어도 무방하며, 이때에도 본 고안 단층트레드타이어(T)가 목적한 바와 같은 동일한 효과를 얻을 수 있음은 물론이다.Figure 4 shows the modified embodiments of the present invention, various modifications other than those shown in the range without departing from the configuration requirements of the present invention may be carried out, and in this case the single-layered tread tire (T) It is a matter of course that the same effects as desired can be obtained.

이와같이 본 고안 단층트레드타이어(T)는 트레드부(1)의 그루브(2)깊이가 증가함에 따라 종래의 타이어에 비해 35-44%정도의 증가된 주행거리를 나타내게 되고, 숄더부의 두께 t가 얇아 효과적인 발열, 방열효과를 얻게 되므로 세퍼레이션 현상을 적극적으로 방지하며, 접지길이 L2의 증가에 따라 종래 타이어에 비해 10-20%정도 향상된 복원토오크를 얻을수 있는 등의 여러 가지 잇점이 있다.As such, the present invention single-layer tread tire (T) shows an increased mileage of about 35-44% compared to a conventional tire as the depth of the groove 2 of the tread portion 1 increases, and the thickness t of the shoulder portion is thin. Effective heat generation and heat dissipation effect can be effectively prevented the separation phenomenon, and the increase in the ground length L 2 has several advantages, such as 10-20% improved recovery torque can be obtained compared to the conventional tire.
