Abstract:
A tire for a furrow press roller comprises a sole via which the tire is mounted on a field roller support, a tread opposite to the sole, and two sidewalls connecting the tread to the sole. The sole, the tread and the sidewalls together delimit a non-inflatable chamber. The tread comprises at least one crest and two shoulders each connecting the crest to a respective sidewall. The chamber extends partially at least laterally under the shoulders and radially into the crest.
Abstract:
A tool for working in fields includes a first flange and a second flange which mount one on the other, forming a wheel body. The first flange includes a central portion, a generally annular peripheral portion and arms which connect the central portion and the peripheral portion to each other. The second flange is homologous to the first flange. In the assembled state, the wheel body has a rim which is formed together by the peripheral portion of the first flange and the homologous peripheral portion of the second flange and a hub which is formed by the central portion of the first flange. The central portion of the second flange receives the hub which is formed by the central portion of the first flange.
Abstract:
Pneumatic tire 1 for an agricultural machine, having an axis of revolution XX and comprising a tread 7, a sole 11 situated opposite the tread 7, and two sidewalls 13, 15 connecting the tread 7 to the sole 11. The tread 7, the sole 11 and the two sidewalls 13, 15 together form a casing 17 defining a chamber 19 inside the pneumatic tire 1. At least one of the sidewalls 13, 15 comprises, in this order and in succession in a direction oriented radially from the axis of revolution XX to the outside, a proximal portion 131, an intermediate portion 133 and a distal portion 135. In the unloaded state, the intermediate portion 133 projects into the chamber 19 in a direction substantially parallel to the axis of revolution XX.
Abstract:
The semi-hollow pneumatic tire has an axis of revolution and comprises a sole mountable on the periphery of a rotary support, a tread opposite the sole, and two sidewalls each connecting the sole and the tread so as to form together a cover which defines an uninflated chamber inside the pneumatic tire. The tread has a concave profile according to a plane passing through the axis of revolution, and the pneumatic tire comprises two annular ridges which extend, respectively, the two sidewalls in the outer radial direction and which are connected to two opposite ends of the tread, the two annular ridges defining, respectively, two principal directions which intersect at an acute angle so that, when the pneumatic tire comes into contact with soil, by being subjected to a vertical load, the two annular ridges move closer together locally.

Abstract:
An agricultural roller comprises a tubular support and a series of pneumatic tyres mounted on the support. Each pneumatic tyre of the series has a respective uninflated envelope. The roller further comprises a series of tyres mounted on the support and interleaved in the series of pneumatic tyres. Each tyre has a respective envelope. The tyres are smaller than the pneumatic tyres while their envelope is narrower.
Abstract:
A press wheel comprises a rigid body and a semi-tubular tire. The tire comprises a flexible envelope with a sole portion through which the tire is mounted on the rigid body, a tread portion and a pair of sidewalls each one connecting the sole to the tread. The sidewalls extend, at least partially, along a generally concave profile, viewed from the exterior of the tire.
Abstract:
A non-inflatable tire for an agricultural implement, including a sole, a tread, and a pair of sidewalls connecting the sole to the tread is provided. A first sidewall extends from the sole to the tread, while the second includes an internal portion which extends from the sole to the tread and an external portion projecting from the tread. The first sidewall and the tread are designed so as to jointly hold the external portion of the second sidewall in line with the internal portion.
Abstract:
An agricultural tool used to form furrows includes a generally cylindrical support and a plurality of tires. Each tire includes a sole by way of which the tire is mounted on the support, a tread opposite the sole (3) and two sidewalls that connect the tread to the sole. The sole, the tread (5) and the sidewalls jointly form a deformable casing. The tread of at least one of the plurality of tires has a generally domed shape. The sidewalls of this tire are generally inclined radially. The domed shape of the tread and the inclination of the sidewalls are such that the deformation of the casing urges the sole axially outward.
