What is claimed is:
1. Quick connection for the removable join of two pipes, said connection comprising a first and a second elements adapted to fit in each other along a principal axis of the connection, the first element comprising at least one ramp for receiving a radially projecting part of the second element, with a view to locking these elements when the connection is in configuration of passage, wherein said ramp is formed in or fast with a ring, mounted on one of these elements, being free to rotate and fixed in translation along the said axis, wherein the ramp forms at least one seat for locking the projecting part when the connection is in configuration of passage and wherein said ramp forms a second seat, offset axially with respect to said first seat in a sense of opening the connection, for locking said projecting part in configuration of decompression of the downstream pipe of the connection.
2. The connection of claim 1, wherein said ramp is delimited by surfaces inclined with respect to said axis and disposed axially opposite hollows forming seats or stops for receiving andor reorienting said projecting part.
3. The connection of claim 1, wherein said ramp is provided with an opening for entrance of said projecting part and with an opening for exit of said part, said openings being oriented () with respect to said axis in two distinct radial directions.
4. The connection of claim 3, wherein it comprises two ramps and two projecting parts, said projecting parts being substantially diametrally opposite, while the inlet opening of a ramp is superposed with the outlet opening of the other ramp.
5. The connection of claim 1, wherein the entrance and exit of said ramp are constituted by a single zone for passage of said projecting part.
6. The connection of claim 1, wherein said ramp comprises an inlet zone converging in the direction of a first passage oriented in the direction of a stop zone corresponding to a configuration of fit of said elements, said stop zone being disposed opposite a surface for guiding said projecting part in the direction of said locking seat when the connection is in configuration of passage.
7. The connection of claim 6, wherein said ramp comprises a second stop zone disposed axially opposite a surface for guiding said projecting part in the direction of said second locking seat.
8. The connection of claim 1, wherein said ramp is equipped with a non-return device compatible with the advance of said projecting part from an inlet zone towards an outlet zone of said ramp in one direction.
9. The connection of claim 1, wherein said ramp is delimited, near its exit, by a nose opposing a direct axial introduction of said projecting part towards a hollow forming stop for said projecting part in said ramp.
10. The connection according to claim 1, wherein said ramp is formed on the internal radial surface of a ring which is mounted free to rotate and fixed in translation within the female element of the connection, and said projecting part is fixed to the male element.
11. The connection according to claim 1, wherein said ramp is formed on the internal radial surface of a body of the female element of the connection and said projecting part is fixed with a ring mounted free to rotate and fixed in translation around the male element.
12. The connection according to claim 1, wherein said ramp is formed on the external radial surface of a ring mounted free to rotate and fixed in translation around the male element of the connection and said projecting part is fixed with respect to the female element and protrudes radially towards the internal volume of this element.
13. The connection according to claim 1, wherein said ramp is formed on the external radial surface of the male element of the connection and said projecting part is fixed with a ring which is mounted free to rotate and fixed in translation within the female element, said projecting part protruding radially towards the internal volume of this element.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A hybrid drive system for integrated stability control, comprising:
a multi-wheeled vehicle originally configured for propulsion using an internal combustion engine, said internal combustion engine capable of driving at least one wheel of said multi-wheeled vehicle, wherein said multi-wheeled vehicle comprises remaining wheels not driven by said internal combustion engine;
a drop-in electric drive motor adapted to independently drive at least one remaining wheel on said multi-wheeled vehicle, wherein said drop-in electric drive motor is adapted to drive a first remaining wheel and a second remaining wheel on the same axle but in opposite rotating directions; and
a master controller coupled to said drop-in electric drive motor for controlling speeds of remaining wheels driven by said drop-in electric drive motor to provide propulsion and overall stability management for said multi-wheeled vehicle.
2.
