摘要:
The invention relates to a wheel (1) with a driven wheel body (2), comprising two support elements (21, 22), between which a number of roller bodies (3) with a spherical surface are arrange to rotate, which at least partly extend beyond the circumference of the support elements (21, 22) the rotational axes of which are arranged at an angle to the rotational axis (23) of the wheel body (2). The ratio of the outer diameter (Du) of the wheel (1) to the maximum radius (Ra) of the roller body (3) is between 1.08 and 1.13, in particular, between 1.09 and 1.12.

An obstacle traversing wheel assembly includes a primary wheel (121) having an even number, at least four and preferably six or eight, of secondary wheels (33) mounted at equal-spaced, fixed locations thereon. The diameter of each secondary wheel is greater than is the distance between locations, and adjacent secondary wheels (33a, 33b) are arranged to roll in separate, parallel paths. The primary wheel (121) is mounted on a yoke (127) that supports a load-bearing frame (125).

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.

La roulette selon l'invention est essentiellement caractérisée par le fait qu'elle comporte un carter 10, un pivot 20 comprenant deux parties 21, 22, la partie 22 comportant deux portions 22-1 et 22-2, la portion 22-1 étant comprise entre la portion 22-2 et la partie 21, et des moyens pour monter la partie 22 en rotation par rapport au carter 10 qui comportent un orifice 30 réalisé dans le carter comprenant une zone 30-1 ayant un diamètre supérieur à la portion 22-1 et une zone 30-2 comprise entre le fond 33 de l'orifice 30 et la zone 30-1, le diamètre de la portion 22-2 étant égal au diamètre de la zone 30-2, une gorge circulaire 25 réalisée dans la portion 22-1, une bague 40 située dans la gorge 25 et ayant un diamètre extérieur égal à celui de la zone 30-1, et un tampon amortisseur 50 disposé entre le fond 33 de l'orifice 30 et la partie 22, le diamètre extérieur de ce tampon amortisseur étant égal au diamètre de la zone 30-2.
摘要:
A vertically-adjustable caster wheel apparatus for use on a forklift truck, material handling cart, and the like. The caster wheel apparatus of the present invention provides a yolk frame having a pivot pin connected to and extending through the yolk frame. A wheel frame has one end pivotally connected to the yolk frame and a second end rotatably connected to a wheel. An elastic member has a first retainer connected to one end of the elastic member and a second retainer connected to an opposite end of the elastic member, wherein the first retainer is connected to the pivot pin in the yolk frame to allow the elastic member to pivot with respect to the yolk frame. Means for adjusting the vertical height of the wheel is provided by adjusting the angle of the wheel frame relative to the yolk frame.

The present invention relates to a wheel to be incorporated preferably in movable automatized equipment, for example, a vehicle remotely controlled. It specifically relates to a rubber body wheel with flexible flaps (4) intended to increase the total contact surface area due to its shape which semi- involves the surface against which it spins. This wheel may be used in vehicles, in small or medium robot vehicles basically used in spy tasks in rough terrain.
摘要:
A wheel (9) having rotating bodies (10) is disclosed wherein a plurality of rotating bodies (10) are disposed around the wheel (9) and are rotatable in a direction orthogonal to the straight-forward direction of the wheel (9). Each of the rotating bodies (10) is rotatably supported around the axis of rotation across the radial direction around an axle (1). Each of the rotating bodies (10) is formed in a shape forming an arc of an outer circumferential circle of the wheel (9) by a circumferential surface (19) with the diameter of a tip portion (12) of the rotating body (10) being smaller than the diameter of a base end portion (11).

An omni-direction wheel (3) for an omni-directional vehicle (1) that exhibits constant ride height, low vibration, and reduced maximum ground contact pressure is disclosed. The invention consists of a wheel assembly rotatably connected to the omni-directional vehicle chassis (2). The wheel assembly comprises a hub on which free spinning rollers are rotatably mounted at an angle to the wheel axis. Constant ride height and low vibration operation are accomplished by configuring the rollers (6) with an exterior profile, thickness, material properties and surface grooving to achieve constant deflection of the roller contact surface at all wheel rotation angles.
