Heavy-duty tire

InactiveUS20050016656A1High level of equalizationInhibits uneven wearPneumatic tyre reinforcementsTyre beadsGround contactEngineering

In a ground-contact surface shape of a tire, when a tangent angle formed between an axial direction of the tire and a tangent X at each point P on a profile line of the tire is defined as θ, a tangent angle θ₁in a ground-contact end point Pd is 25° or smaller. When a minimum value of the tangent angle θ in a region Y which is separated away from a tire equator C by a distance in a range of not less than 0.4 times but not more than 0.7 times a half of the ground-contact width of the tread is defined as θ₂, and a tangent angle at a 0.9 times point Pq which is separated away from the tire equator C by a distance of 0.9 times the half of the ground-contact width of the tread is defined as θ₃, a difference (θ₃−θ₂) is set in a range of not less than −10° but not more than +10°.

A tread portion of a pneumatic ti re includes inner land portions between outer circumferential main grooves disposed most on tread ground-contact end sides and at least one inner circumferential main groove on the inner side thereof. The inner land portions are divided into inner blocks by inner lateral grooves inclined at an angle α of 10 to 40°. The inner lateral grooves consist of first inner lateral grooves and second inner lateral grooves which are alternately arranged in a circumferential direction. The first inner lateral grooves include a wide-width part connecting to the outer circumferential main groove and a narrow-width part connecting to the inner circumferential main groove.

Belt for continuously variable transmission

InactiveUS6599212B2Decreasing V-face heightInhibits uneven wearV-beltsDriving beltsEngineeringPulley

A V-face of a metal element is prevented from being inclined due to a load from a pulley by increasing the height Hs of an upper non-contact portion of the V-face of the metal element. For example, when the height of the V-face is represented by Hv (mm), and the height of the upper non-contact portion of the V-face is represented by Hs (mm), the height Hv of the V-face and the height Hs of the upper non-contact portion are set so that a relationshipis established.

The present invention is to stabilize behavior of brake pads at the time of braking of a disc brake so as to suppress generation of brake noise, and also to reduce the roll moment of the brake pads generated at the time of braking so as to suppress uneven abrasion of linings. A back plate (41) of a brake pad (40) is biased inward in the rotor radial direction by a plate spring (80). The back plate (41) is engaged at two points with an inner periphery support shaft (61) provided integrally with a caliper (20) on a V-shape inner peripheral abutment (41a) (provided in the back plate (41) on the inner side of a lining (42) in the rotor radial direction and on the center in the rotor circumferential direction), and engaged at one point with an outer periphery support shaft (62) provided integrally with the caliper (20) on an outer peripheral abutment (41b) (provided in the back plate (41) on the outer side of the lining (42) in the rotor radial direction and on the center in the rotor circumferential direction).

A heavy duty tire comprising: a shoulder rib (A1) (shoulder rib (A5)) which is provided to a tread shoulder unit; a second rib (A2) (second rib (A4)) which is adjacent to the shoulder rib (A1) with a circumferential groove (110) (circumferential groove (116)) interposed therebetween and is provided further toward the tire equator side than the shoulder rib (A1); and an uneven wear absorbing rib (B1) (uneven wear absorbing rib (B2)) provided within the circumferential groove (110) and located further toward the inside in the tire radial direction than the tread surfaces of the shoulder rib (A1) and of the second rib (A2). Circumferential narrow grooves (10, 12) having a smaller width than the circumferential grooves (110, 116) are formed in the second ribs (A2, A4). Each circumferential narrow groove (10, 12) is formed in such a manner that, when the tire is mounted on the vehicle, the circumferential groove (10, 12) is located on the outer side of the tire with reference to the center of the second rib (A2, A4) in the tread width direction.

Pneumatic Tire

InactiveUS20070204947A1Degraded drivabilityReduced wear resistance requirementsPneumatic tyre reinforcementsWheelsGround contactInternal pressure

The ground contact pressure on land portions 44 is uniformed so that drivability is improved and uneven wear is suppressed to improve wear resistance. The parts of the carcass layer 28 and belt layer 33 overlapping with the main grooves 42 are convexly curved toward the outside in the radial direction due to the internal pressure. The reinforcing layer 49 is arranged at the position spaced from the neutral axis of deformation in the compressed side in a certain distance, i.e. radially inside of the radially outermost carcass ply 30, and the steel cords 47 which extend in the direction including the tire width direction and its approximate direction and which act as supports for resisting against the compression force are embedded in the reinforcing layer. As a result, the above-mentioned curved deformation can be effectively suppressed.

Tire

ActiveCN104275989AInhibits uneven wearInhibit wearTyre tread bands/patternsEngineeringMechanical engineering

Provided is a tire which is configured so that driving stability and water discharge properties on a wet road surface can be maintained and so that the uneven wear of the treading surface of the tread can be minimized. A tire is configured in such a manner that the treading surface of the tread has lands defined by circumferential grooves extending in the circumferential direction of the tire, each of the lands having arranged therein lateral grooves extending across the land. The lateral grooves are arranged so that, when the lateral grooves are projected on the equatorial plane of the tire, lateral grooves adjacent to each other in the circumferential direction of the tire do not overlap each other. Each of the lateral grooves is composed of: a center region extending tilted relative to the width direction of the tread; and side regions extending from both ends of the center region toward circumferential grooves at a tilt angle relative to the width direction of the tread, the tilt angle being less than the tilt angle of the center region. Each of the side regions has a groove width expanding toward a circumferential groove. The lateral grooves have sipes extending inward in the radial direction of the tire from the bottoms of the lateral grooves, each of the sipes having a shallow bottom only in the center region, the shallow bottom being disposed near the boundary between at least the center region and a side region in such a manner that the start point of the shallow bottom is located at a distance from the boundary.
