Definitions

• Anti - rotation pedestal for hydraulic fluid conveying pipe and hydraulic pump with such pedestal
• the present invention relates, in general, to hydraulic transmission systems for a motor vehicle.
• Such a hydraulic transmission system conventionally comprises a high pressure pump connected to a pump supply device, comprising one or more supply pipes.
• the present invention is obj and a base for maintaining an oil supply device of a hydraulic pump.
• the transmission system comprises a coupling device between a drive shaft driven by the powertrain and a motorized axle.
• the latter comprises two half shafts bearing wheels, the hydraulic pump, and a shaft adapted to drive said pump.
• the hydraulic pump is fed with pressurized oil, conventionally, by an oil inlet hose, or hose.
• a flexible oil outlet hose is used to route the pressurized oil to the transmission system.
• the oil inlet and outlet hoses are attached to the pump by a suitable connector including a hex nut that must be tightened during assembly.
• the hydraulic hoses have a flexible part, which has the disadvantage of having their position evolve during assembly or during maintenance.
• the object of this invention is to overcome the problems of faulty positioning or misalignment of the hydraulic hoses of the pumps.
• the invention thus relates to a base for maintaining a feed device for a hydraulic pump, such as a pipe feeding. It comprises means for fixing and centering the base on a hydraulic pump casing, and means for guiding the feed device of the hydraulic pump.
• the base thus makes it possible to guide and maintain the transport pipes in a position that respects their initial orientation, a desired radius of curvature and guarding, and avoids contact between the pipes, during assembly and / or permanently.
• said means for fixing and centering the base on the hydraulic pump casing comprise a centering groove adapted to cooperate with a tongue formed on the surface of the hydraulic pump casing, and at least one fixing screw provided for traversing a portion of the casing. base and tighten into a threaded hole in the hydraulic pump housing.
• said guiding means comprise at least two substantially parallel arms and spaced so as to allow the embedding of at least one feeder device of the hydraulic pump between said arms.
• said guide means are further adapted to prevent at least one pipe embedded in said arms, to pivot.
• said guide means are placed vis-à-vis the fastening means.
• Said guide means can also maintain said feeder in an orientation that favors oil flow and minimizes bulk.
• the invention also relates to a hydraulic pump comprising a base as defined above.
• This hydraulic pump is connected to a feed device and is intended to supply hydraulic fluid, such as oil, the transmission system of a vehicle.
• FIG. 2 represents a side view of a portion of the pump of FIG. 1;
• FIG. 3 shows another schematic side view of the pump of Figure 1 comprising the holding base fixed on the housing of the hydraulic pump;
• FIG. 4 shows a schematic side view of the holding base
• FIG. 5 shows a bottom view of the base and the housing of the hydraulic pump according to another embodiment of the invention.
• the pump is intended to supply hydraulic fluid, such as oil, to a transmission system of a vehicle.
• the pump is associated with a feed device which comprises one or more feed pipes 5, provided to cooperate with at least one orifice made in the pump casing.
• a supply pipe is adapted to convey the hydraulic fluid to the pump, and a second supply pipe is adapted to convey the hydraulic fluid under pressure from the pump to the vehicle transmission system.
• the pump comprises a holding base 1 of the supply device.
• the base comprises arms 10, 11 and 12 for holding and guiding, by embedding, the supply pipe 5.
• FIG. 2 which shows the pump of FIG. 1 in a supposed vertical position
• the base 1 is fixedly fixed under the casing 2 of the hydraulic pump. It comprises an upper portion 3 and a lower portion 4 integrally fixed together, or are molded or machined together in a single piece.
• the upper part 3 of the base is further adapted to lidarise the base with the casing 2 of the hydraulic pump by means of fastening and centering means not shown in Figure 2.
• the lower portion 4 is adapted to ensure the maintaining functions in the position of a pressurized oil supply pipe 5, in particular thanks to its two arms 10 and 11.
• the pressurized oil supply pipe 5 comprises a flexible part 6 and a hydraulic connector 7. It is connected to the casing of the hydraulic pump 2 by means of a male / female end of the connector which comprises a nut 8 designed to cooperate with one of the orifices 01, made at the lower end of a protuberance 9 formed under the casing 2 of the hydraulic pump.
• the lower part 4 of the base 1 comprises three arms delimiting two U-shaped cavities, facing downwards, in which two supply pipes 5 are housed.
• the cavities by their geometric shape, are able to partially cover two feed pipes, and thus maintain them, and guide them, when embedded in these cavities, in an orientation substantially parallel to the arms that surround them.
• the housing 2 comprises a tongue 13 extending longitudinally under said housing.
• This tongue is adapted to cooperate with a centering groove 14 formed in the upper part 3 of the base.
• the base is thus advantageously fixed in a single position, and is held there by means of a fastening screw 16 which is screwed into a threaded hole of the housing, passing through a portion of the base.
• the arm 1 1 ensures the non-contact holding of two arms 5 and 15.
• This arm constitutes a spacer which ensures a separation of the two pipes 5, 15 respectively connected to the orifices 01, 02 visible in FIG.
• the guide means formed by the parallel arms and spaced, are positioned vis-à-vis, that is to say under the fixing means of the base on the housing.
