Definitions
- Conveyor for conveying oil from a reservoir to a transmission of a motor vehicle
- the invention relates to a conveyor for conveying oil from a reservoir to a transmission of a motor vehicle with an optionally driven by a mechanical direct drive or by a switchable electric drive oil pump, which has two relatively movable components for conveying the oil that the mechanical direct drive with a the relatively movable components and the switchable electric drive with the other of the relatively movable components is connected, and that the relatively movable components are arranged in a pump stage housing, consisting of two control discs and egg ⁇ nem intermediate ring.
- Such conveyors are used in particular in motor vehicles with hybrid drive.
- the oil pump for supplying a transmission ⁇ di rectly from the gearbox is driven at such a ⁇ Hybridan driven. At standstill of the gear ⁇ bes whose function should be maintained and therefore the oil pump remain in operation.
- ⁇ driving device for a transmission oil pump May be the oil pump ⁇ depending on the design of the relatively movable components, a vane-cell pump, gear pump, or G-Ro torpumpe.
- the radially inner of be ⁇ movable relative to each other components is rotatably mounted on a shaft and driven by the direct drive.
- the pumping stages housing is arranged rotatably on a hollow shaft and drive by the electric ⁇ driven.
- the pumping stages housing can be arranged in a recess of the housing of the oil pump, wherein Zvi ⁇ rule housing and pump stage housing a seal is arranged.
- This seal is arranged so that oil over a Inlet in the housing and an inlet channel is sucked in a control ⁇ disc and leaves after passing through the mutually movable components and the associated pressure increase via an outlet channel in the opposite control disc and the outlet in the housing, the oil pump.
- the disadvantage here is, on the one hand, that the screw connection of the control disks with the ring is located radially outside the components which are movable relative to one another, as a result of which the rotor part has a large outside diameter.
- the pressure in the rotor part promotes the formation of a Axialspal ⁇ tes, which has a negative effect on the efficiency.
- the invention is based on the object, a winning ⁇ tion of the type mentioned in such a way that it has a smaller space with better efficiency.
- the object is achieved in that the pumping stage housing is arranged in a pot-shaped component.
- the topfformige component is the component which is to be disposed in the housing of the oil pump Anlagenpas ⁇ sen. Characterized the pump stage housing can be configured easily by the USAGE ⁇ dung conventional components. The conveyor is thereby cheaper. Next the topfformige component allows a simpler arrangement and attachment of the pump stage housing, so that the Pumpgenge ⁇ housing and thus the oil pump has smaller radial dimensions and thereby requires less space. Due to the smaller dimensions, bearings and seals with a smaller diameter can be used so that the efficiency increases as a result of lower coefficients of friction. Finally be ⁇ acts topfformige the housing such that the outer side of the outlet-side off control disc is exposed to the generated pressure, resulting in a reduction of the axial gap of the pump stage and also leads to an increase in the effect ⁇ degree.
- An additional securing element for clamping is avoided according to another embodiment in that the open side of the cup-shaped component is crimped or caulked for the axial clamping of the pump stage housing.
- the bottom of the cup-shaped component may have corresponding form elements such as shoulders or inwardly directed grooves which generate a distance between the bottom and pump stage housing.
- Such Formge ⁇ staltung of the soil is avoided when the PumpgengePSu ⁇ se is axially clamped with a sealing ring against the bottom of the cup-shaped housing.
- This embodiment also has the advantage that tolerance compensation takes place via the sealing ring.
- the supply of the oil to be sucked from the inlet of the oil pump to the pumping stage is carried out in a simple manner in that in the casing surface of the pot-shaped component openings are angeord ⁇ net, which are in communication with the inlet channels of the pumping stage.
- the torsional safety of the pump stage housing with the cup-shaped component can be further increased if tabs for engagement in the pump stage housing are arranged on the lateral surface of the cup-shaped component.
- tabs for engagement in the pump stage housing are arranged on the lateral surface of the cup-shaped component.
- Separate shots In the pump stage housing for the tabs are avoided in an advantageous ⁇ haften embodiment characterized in that the tabs engage in the channels of the pump stage housing.
- the base of the cup-shaped member merges into a hollow shaft, whose diameter is klei ⁇ ner than the lateral surface of the pot-shaped component.
- the cup-shaped component can be stored in the housing via the hollow shaft, whereby due to the small diameter, no additional installation space in the radial direction is required.
- the small dimensions also have an advantageous effect on the weight and efficiency of the oil pump.
- a particularly simple derivation of the pumped oil to the outlet in the housing is achieved in that the hollow shaft ra ⁇ dial has arranged openings.
- the oil pump has two relatively movable components, wherein the mechanical direct drive is connected to one of the relatively movable components and the switchable electric drive with the other of the relatively zuein ⁇ other movable components.
- the conveyor according to the invention also allows a parallel operation of the direct drive and the electric drive, for example, if the electric drive should be started early, before the direct drive is turned off. Just ⁇ so the capacity of the oil pump can be raised by switching the electric drive when the direct drive runs in an operating condition with too low speed.
- the oil pump is according to another advantageous development of the invention a particularly simple construction, when the topfformige component relative to a stationary housing of the oil pump is rotatably supported and sealed by a Radi ⁇ aldichtung, and when the intake and Auslassan- Conclusions for the hydraulic connection of the oil pump to the Ge ⁇ housing are arranged.
- the conveyor according to the invention is particularly compact when the housing has a common recess for an electric motor of the electric drive and the cup-shaped component. As a result, the electric motor is cooled by the extracted oil and its noise is damped. Furthermore, this eliminates the sealing of a shaft passage for the electric drive.
- a proposed drive torque during operation of the oil pump by the electric drive can be easily adjusted according to another advantageous embodiment of the invention, when the electric drive has a reduction gear.
- the cup-shaped component could, for example, have a circumferential toothed ring on the lateral surface on which the respective drive is articulated.
- the oil pump is of particularly compact according to another prior ⁇ part embodiment of the invention, when the rotor is mounted on a shaft of a drive and the cup-shaped member is in the area of the bottom being ⁇ formed hollow shaft connected to the other drive.
- the drives can also be connected to the respective other part in kinematic reversal.
- the hollow shaft is guided exclusively within the Ge ⁇ housing, so that the sealing of a shaft bushing is avoided.
- the oil pump consists of particularly few components to be mounted when the ring or the control plates have the oil supply elements.
- a mutual influence of the drives with each other can be easily avoided according to another advantageous embodiment of the invention, when the direct drive and the electric drive are designed to be self-locking.
- the oil pump can be driven particularly advantageously by two different drives when the oil pump is designed as a toothed ring pump, as a vane cell pump or as an external gear pump.
- the oil pump is designed as a toothed ring pump, as a vane cell pump or as an external gear pump.
- pumping principles of the correspondingly shaped rotor and a rotor ring surrounding cooperate such that in a particularly easy way of selectively ⁇ , the ring or the rotor for promoting the oil angetrie- ben can be.
