摘要:
A sealant rubber composition which forms a spongy tacky sealant layer having moderate viscosity properties; and a pneumatic tire having in the tire main body a tacky sealant layer obtained by heating the rubber composition. The rubber composition comprises 0.2 to 20 parts by weight of a peroxide per 100 parts by weight of polymers comprising 95 to 50 parts by weight of a polymer decomposable with the peroxide and 5 to 50 parts by weight of a polymer crosslinkable with the peroxide.
摘要:
A pneumatic tire of which self-seal function can be improved while the increase in weight of the tire is minimized. The pneumatic tire contains a rubber component decomposed by peroxide and 0.2 to 20 parts by weight of peroxide per 100 parts by weight of the rubber component. An adhesive sealant layer constituted from a rubber composition where fibrillated short fibers with an average length of 100 to 5000 μm are mixed and scattered are arranged in the region corresponding to at least a tread portion at the inner side of the tire.
摘要:
A self-seal tire having a puncture seal layer applied to the entire inner wall face of the tire from one shoulder part to the other shoulder part of a pneumatic tire. The puncture seal layer comprises an adhesive layer of a material bonding to the inner wall face of the tire provided on the outer circumferential surface of an annular sponge layer impregnated with an adhesive material such that it is exposed to the outer circumferential surface side. The puncture seal layer is pressure bonded to the inner wall face of the tire by the restoring force of the sponge layer applied while being compressed.
摘要:
A pneumatic tire which makes it possible to effectively prevents puncture during running without involving a large increase in weight or degradation of riding comfortability. This pneumatic tire has a plurality of films disposed in the manner of fish scales in at least a region corresponding to the tread portion of the inner surface of the tire, some of the films being fixed on the inner surface of the tire, the fixed portions of the films being covered by the non-fixed portions of the other films.
摘要:
A control input for drive/brake force operation of one or more specific wheels, i.e. a k-th wheel, out of a plurality of wheels of a vehicle is determined to satisfy the requirements for the relation between a road surface reaction acting on the k-th wheel from the road surface depending on the detection values or estimated values of the road surface reaction and the frictional characteristics of the k-th wheel, a feedback control input concerning the drive/brake force of the k-th wheel for bringing the difference between the quantity of state and a model quantity of state of the vehicle close to 0, a feed forward control input of drive/brake force dependent on a drive controlled variable by the driver of the vehicle, and a control input for drive/brake force operation of the k-th wheel. Consequently, actual motion of the vehicle can be controlled to a desired motion while taking account of the characteristics of road surface reaction acting to the wheel from the road surface appropriately.
摘要:
An actual vehicle actuator operation control input and a model operation control input are decided by the FB division rule (20) so that a difference (state amount deviation) between a normal state amount decided by a vehicle model (16) and an actual state amount of an actual vehicle (1) approaches 0. The control inputs are used to operate an actuator device (3) of the actual vehicle (1) and the vehicle model (16). The parameter value of the vehicle model (16) is variably set in accordance with a motion state of the actual vehicle (1) so that the attenuation of the normal state amount when the driving operation amount (steering angle) is stepwise changed is higher than the attenuation of the actual state amount. Thus, it is possible to control the actuator device (3) of the actual vehicle (1) so that the state amount (actual state amount) concerning the motion of the actual vehicle approaches the vehicle state amount (normal state amount) on a dynamic model (vehicle model (16)) without depending on the motion state of the actual vehicle (1).
