Provided is a non-pneumatic tire having excellent durability performance. This non-pneumatic tire is provided with an annular tread portion which contacts the road surface, an annular inner peripheral portion which is positioned radially inward of the tread portion, and multiple linking units which join the tread portion and the inner peripheral portion. The tread portion includes a first portion which contacts the road surface, and a second portion which includes an inner peripheral surface facing the inner peripheral portion. The thermal conductivity of the second portion is greater than that of the first portion.

A caster wheel assembly includes a wheel mounted for rotation about a horizontal axis within a wheel carriage such that the wheel rotates about the horizontal axis with respect to the wheel carriage. The wheel carriage is positioned within a retention ring such that the wheel carriage can rotate about the vertical axis with respect to the retention ring. The wheel carriage also has an opening on the bottom surface such that the wheel can make contact with the ground. The horizontal axis about which the wheel rotates is offset from the vertical axis about which the wheel carriage rotates. An outer carriage may be included such that the outer carriage is positioned within the retention ring and the wheel carriage is positioned within the outer carriage. The outer carriage would be able to rotate about the vertical axis with respect to both the retention ring and the wheel carriage.

The invention relates to an adapter for a rolling assembly having an axis of rotation comprising a tyre having two beads, a rim having a well (13) positioned between two rim seats (12) each having an axially outer end, said rim having a total width W between each axially outer end of said two rim seats, said adapter making the connection between each bead and each rim seat, said adapter having two axially outer ends (2) each comprising an adapter seat (3) and an adapter bearing face (4) substantially comprised in a plane perpendicular to the axis of rotation, a body (5) connecting said two axially outer ends (2) so as to form a one-piece component and comprising at least one main reinforcement, a face (16) intended to be in contact with each rim seat (12) and with the well (13) and arranged radially on the inside said adapter having a total axial width L comprised between each adapter seat (3). The invention is characterized in that the ratio W/L is greater than or equal to 20 and less than or equal to 60% and in that said body comprises an immobilizing element (8) intended to immobilize said adapter in the well (13).

A wheel assembly (200) includes a wheel (202) and a hub assembly (400). The hub assembly (400) includes a retainer housing (600), retaining member (700), biasing element (800), and restraining element (900). The retainer housing (600) includes a wheel mounting sleeve (602) and pin sleeve (604). The wheel mounting sleeve (602) includes an axle bore configured to receive an axle (150) and configured to be inserted within a sleeve bore (210) of the wheel. The pin sleeve (604) includes a first end fluidly communicating with the sleeve bore (210), a second end, and a conduit therebetween. The retaining member (700), disposed within the conduit, is configured to operatively engage an axle groove (152) and includes a lip (704) wider than a first end shoulder to prevent the retaining member (700) from exiting the first end. The biasing element (800), disposed within the conduit, is configured to bias the retaining member (700) towards the axle bore. The restraining element (900) is configured to prevent the retaining member (700) from exiting the second end.
摘要:
Une roue pouvant absorber les vibrations de hautes fréquences et faibles amplitudes, ainsi que les vibrations de basses fréquences et fortes amplitudes ou les vibrations de moyennes fréquences et moyennes amplitudes, comporte une bande de roulement (1) en matériau tendre portée par une jante (2) creuse, déformable élastiquement, l'ensemble bande de roulement (1)-jante creuse (2) étant relié à son support en un point décentré par rapport au centre de rotation (0) dudit ensemble (1-2).
摘要:
Improved vehicle wheel construction with a peripheral rim, a central wheel hub and a plurality of spokes extending between the rim and hub, wherein the spokes have a first peripheral portion connected to the rim and a second central portion opposed to the first portion. The hub includes at least two opposed outer flanges, with the central portions of the spokes secured to at least one of the outer flanges by hardened molding material.
