摘要:
The present invention generally relates to a tyre and wheel construction, and more particularly to a non-pneumatic composite integrated tyre and wheel construction, fabricated from composite layers incorporating interconnected reinforcing internal frame elements. Whilst the present invention is applicable to fabrication of motor vehicle wheels, it is to be appreciated that it is not limited to that application.

A lawn mower wheel (2) is provided. The lawn mower wheel (2) comprises a hub (3) arranged for attachment to a lawn mower wheel axle extending in an axial direction. The lawn mower wheel (2)comprises a tread (4). The tread (4)has a tread width (8) in the axial direction. The tread is a web structure of material portions (6) separated by through openings (7) to reduce the area of the tread (4) onto which grass clippings may attach. The lawn mower wheel (2) comprises a rim (5). The rim (5) extends from the hub (3) to the tread (4). The rim (5) has a rim width (9) in the axial direction. The rim width (9) corresponds to less than half of the tread width (8), to allow grass clippings to fall from one through opening (7) of the tread (4) to another.

The present invention refers to a solid tread (20) for an industrial truck wheel (10) or an industrial truck roll (10), where at least one of the side surfaces (20a, 20b) of the tread (20)has an electrically conductive coating (30a, 30b) that reduces the generation of electrostatic charge in the tread (20). The invention further refers to an industrial truck wheel (10) with such a tread (20), an industrial truck with such an industrial truck wheel (10) as well as a method of reducing generation of electrostatic charge at an industrial truck wheel (10).

A non-pneumatic tire comprising side cavities that are staggered with respect to laterally opposing side cavities, and laterally extending tread grooves that are in substantial radial alignment with the cavities. In another embodiment, the invention is to a tire comprising side cavities that are staggered with respect to laterally opposing side cavities, and laterally extending tread grooves that are substantially offset relative to the side cavities. The side cavities may be separated by ribs which are either radial oriented or are angled relative to the radial direction. The tread grooves may have walls at are straight or angled relative to the radial direction. Also provided are processes for making such tires and to off-the-road (OTR) vehicles employing such tires.

This invention relates to a tyre insert (1) comprising an inner component (30) comprising a first foam material, and an outer component (35) comprising a second foam material, wherein the second foam material has either a higher or lower density than the first foam material, and wherein the outer component comprises an inwardly facing channel (50) which is shaped to accept the inner component. This invention also relates to a wheel for a vehicle comprising a tyre insert as described above, as well as to a vehicle comprising the wheel.
摘要:
The invention relates to a method for forming a nonpneumatic tire that is constructed from a thermoplastic elastomer which is pre-tensioned during the process of its formation. The Pretention is provided by a thermal means that is naturally available in the forming process. This creates an efficient process of manufacturing by creating pretention without the complexity of adding pretention from mechanical means. The method for forming the non-pneumatic tire includes inserting a tread portion (101) and an annular beam (102) having circumferential reinforcement into a mold, the mold supporting the tread pattern only on an outer radial extent of the tread pattern, inserting a rim (104) extending radially inward from the annular beam (102), and forming an annular support (103) comprised of a thermoplastic elastomer extending radially inward from the annular beam (102)). The thermoplastic elastomer is allowed to harden and the tire is removed from the mold.
摘要:
A non-pneumatic tire (100) having an annular beam (200) and an annular support (103) comprising a plurality of thermoplastic elastomeric spokes formed by a thermoplastic injection process. When manufacturing this non-pneumatic tire via a mold, then the radial extent of a mold cavity is defined by the radially inner extent of the annular beam (200). The non-pneumatic tire's annular beam (200) includes a first elastomer and a circumferential reinforcement extended in a circumferential direction. The annular beam (200) is free of the circumferential reinforcement at an axial extent over a width of at least 8 mm the axial extent comprising the first elastomer. The plurality of thermoplastic elastomeric spokes are made of a second elastomer and extend radially inward from the annular beam (200). The present invention also refers to a process for forming such a non-pneumatic tire (100).
摘要:
A method of curing spokes (10) is provided in which first molds of a first (14) and second series (16) of molds are placed into a platen, and force and heat applied. The platen (12) is opened and the first mold (1(1)) of the first series (14) is moved relative to the platen while the position of the first mold (1(2)) of the second series (16) is kept the same relative to the platen. Force and heat are applied to the molds. The platen (12) is opened, and the first mold (1(1)) of the first series is removed while the second mold (2(1)) of the first series is kept within the platen. A cured spoke is removed from the first mold of the first series.
摘要:
A mold for manufacturing a spoke for a non-pneumatic tire that has first and second mold pieces movable relative to one another with first and second engagement surfaces. First and second end pieces (24,26) ) are present and the engagement surfaces are between them when the mold is closed. First and second flashing voids (28, 32) are present, and flashing is disposed within them during spoke molding. When the mold is opened and relative movement between the first and second mold pieces takes place, the flashing voids with disposed flashing are configured for causing the spoke to be urged off of at least one of the first and second engagement surface.
摘要:
A method for assembling an uncured spoke is provided. The method includes the assembly of a panel (14), a first foot (24), and a second foot (26) of the uncured spoke. The first foot (24) and the second foot (26) are complexed onto the panel (14), and the panel extends continuously from the first foot to the second foot.
