摘要:
A volumetric pump for paste-like material, for example, unvulcanized rubber, in which a screw 21 feeds a cylinder 11 through ports 12 and in which a delivery piston 10 within the cylinder displaces the material through a non-return valve 15. A process for volumetric pumping of the material utilizing such volumetric pump.
摘要:
The continuous mixing apparatus for preparing a rubber composition has a mixing chamber accommodating at least one rotor rotating in a stator and extending between an upstream end and a downstream end between which the material progressively passes. The base elastomers are introduced at the upstream end of the mixing chamber by means of volumetric pumps capable of delivering the said base polymers under pressure. It has members for the dosaging and forced introduction of the other components, to arranged along the mixing chamber at at least two longitudinally separated positions between the upstream end and the downstream end.

摘要:
A tire comprising an airtight rubber cover (2) and a reinforcing structure essentially formed of a plurality of fibers (30, 40) embedded in the rubber and arranged in layers, this reinforcing structure comprising at least one carcass layer (3) and one crown layer (4). The fibers (30) and (40) of these layers (3, 4) are connected together and oriented, with respect to the median plane (P) of the tire, at respective angles of the order of 90 degrees and 0 degrees, each of these fibers (30, 40) also having a connected cross section of flattened shape.
摘要:
A tire comprising an envelope made at least partly of rubber, defining an internal annular volume and having a crown (1), which defines a tread, two sidewalls (2) joined to the crown (1), and a supporting structure (4). The supporting structure (4) is pressurized and divides the annular volume of the tire into a plurality of compartments (400) or cells, and the sidewalls (2) are connected to or integral with the supporting structure (4).
摘要:
The invention relates in particular to a passenger vehicle tire, the crown reinforcement of which consists of: a radial carcass reinforcement, a working reinforcement consisting of a single layer of reinforcers inclined by an angle “α” with respect to the circumferential direction (DC) of the tire, the angle α being between 4 and 7 degrees, a flat circumferential polymer reinforcer positioned in a central portion of the crown.
摘要:
A wheel support system (3, 5, 6) designed to connect a wheel to suspension elements (4) of a vehicle. The wheel support system includes a curved slide (6) or two levers (54, 55) which confer upon the wheel carrier (3) a degree of camber freedom relative to the suspension elements (4), and a triple hinge (5, 51) that operates along three essentially longitudinal axes. The triple hinge (5, 51) is connected on the one hand to the wheel carrier (3) and on the other hand to the suspension elements (4).

A wheel support system (3, 5, 6) designed to connect a wheel to suspension elements (4) of a vehicle. The wheel support system includes cambering means which confer upon the wheel support (3) a degree of camber freedom relative to the suspension elements (4) and a triple hinge (5) that operates along three essentially longitudinal axes, which is connected on the one hand to the wheel support (3) and on the other hand to the suspension elements (4).
摘要:
The invention relates to a suspension device (1; 11) intended to connect a wheel carrier (3) to a body (5) of a vehicle, the device having means (4, 8, 9) conferring to the wheel carrier, with respect to the body, a degree of camber freedom and a degree of suspension deflection freedom substantially independent of one another. The said means comprises an intermediate support (4) linking the wheel carrier to the body, the intermediate support being, on the one hand, articulated with respect to the body along a substantially vertical first axis (ASI) and, on the other hand, articulated to the wheel carrier along a second axis (R1R2), so that a rotation of the intermediate support about the first axis permits the degree of camber freedom.
摘要:
A rotary plug 1 has recesses 5 debouching on its side face 12 which are in communication with the inlet 6 and recesses 5 debouching on its side face 13 which are in communication with the outlet 7. These recesses 5 pass across a port 4 which permits passage to and from a unit consisting of cylinder 2 and piston 3.
