Definitions
- Pneumatic wheel fitted with inflation means which can be actuated by rotation of the wheel.
- the present invention relates to a tire wheel fitted with inflation means which can be actuated in rotation of the wheel.
- a tire comprising two sidewall portions and a portion of tread delimiting an annular inflation chamber, the tire comprising a single deformable element extending between the portions of sidewall of the tire to limit the circumferential flow of a gas in the annular chamber.
- a device is of complex structure, requiring a special arrangement of the tire.
- the effectiveness of this device is doubtful, in particular in the case of a puncture with a flat tire.
- DE-A-2 746 757 also discloses a self-inflating wheel having an air pump mounted on the rim, inside or outside the tire, with a pump rod projecting from the inside the tire and actuated, directly or by a lever, by the bends of the deflated tire when it rolls.
- the pressure in the tire is maintained by an overpressure control valve.
- Such a device is extremely vulnerable and fragile and, again, its effectiveness is zero when the tire is flat.
- the present invention aims to provide a new device for inflating a wheel tire which does not have the drawbacks of known devices, in particular which does not have a mechanism inside the tire and does not require special fitting of the tire. , while allowing the inflation of a completely flat tire.
- the subject of the present invention is a pneumatic wheel fitted with inflation means which can be actuated in rotation of the wheel, characterized in that said means comprise at least one pump or a mechanical compressor mounted on the wheel hub or at in the vicinity of the latter, outside the tire, said pump or said compressor having a compressed air outlet connected to the tire or to the air chamber of the tire by means of a non-return valve, the pump or the compressor being subject to a control member, such as a cam, mounted fixed in rotation relative to the wheel and capable of occupying, under the action of remote control means, an active position in which the control actuates the pump or the compressor during the rotation of the wheel and at least one erased inactive position in which said control member does not act on the pump or the compressor.
- a control member such as a cam
- the remote control means make it possible to trigger the actuation of the pump or of the compressor if necessary then to stop this actuation when the tire has been sufficiently inflated.
- the pressure obtained in the tire is sufficient to allow the vehicle to roll to a place where the tire can be repaired.
- the wheel comprises two pumps or compressors arranged diametrically opposite on the wheel hub, said compressors or pumps being subject to a control member, such as a cam, mounted fixed in rotation on the hub.
- a control member such as a cam
- the cam has a substantially diamond-shaped profile.
- the latter acts in compression simultaneously on the head of the pumps or compressors by its longest ends when these ends pass opposite the heads at each wheel revolution, either the case of two pumps or compressors and a cam with two active ends, twice per wheel revolution.
- FIG. 1 represents a schematic side elevation view, partially in section, of the rim of a wheel according to an exemplary embodiment of the invention, with the inflation control means in the active position,
- FIG. 2 represents a view in axial section of the rim of FIG. 1, with the inflation control means in the inactive position and,
- FIG. 3 represents a schematic plan view of part of the remote control means.
- the example shown and described relates to a rear spoke wheel for a motorcycle, but the invention can be used for any type of wheel. 5
- the tire wheel according to the invention comprises inflation means which can be actuated remotely and which are active in rotation of the wheel.
- H These means comprise two mechanical pumps or compressors mounted on the hub 1 of the wheel and diametrically opposite.
- Each of the pumps or compressors comprises a tubular body 14 closed at its outer end by a cylinder head 16 fixed by screws 15.
- a piston 19 secured to a rod 11 slides in the body 14 against the action of a spring 12.
- the rod 11, provided with a guide lining 13, carries, opposite the piston 19, a head 4.
- the cylinder head 16 has an air intake opening 17 and an air outlet opening 18 compressed.
- the axis 2 of the wheel hollow over part of its length and open at its end close to the brake drum 22, is
- the pusher 9 carries a diamond-shaped cam 3,
- the assembly is held by the bolts (not shown) for mounting the wheel screwed onto the threaded ends 20, 20 ' of the axis 2.
- the axis 2 carries holes 7 for mounting the chain sprocket.
- each pump is connected to a distributor D, itself connected by a tube T to the valve (not shown) of the tire.
- Distributor D has a valve V set for venting, open when the pressure in the tire is greater than a predetermined value.
- the head of the pusher 9 is actuated by a lever 23 pivotally mounted on a support 26 integral with the fork 24.
- the lever 23 is controlled by a cable 29 sliding in a sheath 28 stopped by a seat 27 with the interposition of a tensioning nut 25
- the cable 29 is conventionally secured to a control member, such as a handle (not shown), mounted on the handlebars of the motorcycle.
- each tip of the cam 3 pushes back the head 4 of a pump which is therefore actuated twice per revolution.
- the outside air sucked in through the suction opening 17 is discharged under pressure at each operation through the outlet opening 18 and arrives at the distributor D, from where it reaches the tire valve. If the pressure in the tire is sufficient, the valve V is open.
- the invention can be used when the vehicle is stopped by lifting a driving wheel and turning it by means of the vehicle engine. It is thus possible to re-inflate a flat tire.
