TECHNICAL FIELD

The present disclosure relates to an oil filter arrangement for filtering oil of a vehicle, an oil pump and oil filter arrangement for pumping and filtering oil of a vehicle, and a vehicle with such an arrangement.

BACKGROUND

Oil filter arrangements, filter arrangements, oil filter units, or filter units are configured to be attached to a housing of an engine, transmission, and/or, in particular, an electrical drive axle, whereby the oil filter arrangements, filter arrangements, oil filer units, or filter units are connected to the respective housing from the outside of the housing. The oil filter arrangement, filter arrangement, oil filter units, or filter unit is thereby connected to the respective housing by means of fixture features, fastening elements and/or threaded joints. Further, some oil filter units or filter units are integrated in the respective housing, whereby these oil filter units or filter units are not considered to be replaced, for example during a service.

SUMMARY

It is found that a further need exists to provide an improved oil filter arrangement for filtering oil of a vehicle.

In the view of the above, it is an object of the present disclosure to provide an improved oil filter arrangement for filtering oil of a vehicle.

The problem is at least partially solved or alleviated by the subject matter of the independent claims of the present disclosure, wherein further examples are incorporated in the dependent claims.

According to a first aspect, an oil filter arrangement for filtering oil of a vehicle is disclosed, comprising:

• • at least one filter unit for filtering the oil; and
  • at least one connection unit comprising at least one inlet tube configured to be connected with an outlet tube of a separate oil pump unit;
  • whereby the oil filter arrangement is configured to be housed in an oil filter arrangement housing of the vehicle.

The at least one filter unit may be configured an oil filter unit which may for example be configured as a spin-on oil filter type or a cartridge oil filter type.

In other words, the oil filter arrangement may be housed in an existing housing and/or a special housing of the vehicle. Thereby, it may no longer be necessary to provide a special housing for a filter unit or to use a filter unit with an extra housing. This means that, for example, replacement of a housing for a filter unit may be avoided or saved, so that the disclosed oil filter arrangement may save consumption materials in the use and/or replacement of an oil filter arrangement.

In an implementation, the at least one connection unit may comprise at least one contact element configured to get in contact with at least one contact element of the separate oil pump unit.

In other words, the at least one connection unit may have dedicated contact pads, similarly to an oil pump may have dedicated contact pads, which may be configured to mate together during assembly to prevent the filter from moving out of position.

In an implementation, the at least one connection unit may comprise at least one guiding element configured to be housed in a recess of the vehicle corresponding to the at least one guiding element.

In other words, the at least one filter unit may be guided with a cylindrical portion, which may be arrangement at the bottom of the at least one filter unit and may be inserted into a corresponding hole of the oil filter arrangement housing.

Further, the guiding element may also be described as a notch that may be mated with a slot in the oil filter arrangement housing.

Furthermore, the guiding element may also be described as a protruding feature that may be located at the bottom of the at least one filter unit and center the at least one filter unit to a corresponding small hole at the bottom of the oil filter arrangement housing.

In an implementation, the at least one connection unit may comprise at least one rotational orientation element configured to be connected to at least one rotational orientation element of the vehicle to restrict a rotation of the oil filter arrangement about a longitudinal axis thereof.

In an implementation, the at least one connection unit may comprise at least one radial groove and at least one radial hole configured to transfer the oil from the at least one filter unit to the vehicle.

In other words, the at least one radial groove and the at least one radial hole may be configured to provide for outlet of oil from the at least one filter unit in a radial direction rather than an axial direction.

For example, one radial groove and two radial holes, preferably four radial holes, may be used to transmit the oil.

In an implementation, the at least one connection unit may comprise at least two or more sealing elements configured to seal a connection between the at least one connection unit and the oil filter arrangement housing of the vehicle.

In other words, the oil filter arrangement may be sealed against the oil filter arrangement housing by two sealing elements, and the oil filter arrangement may be located inside a wet environment and therefore leakage would not be critical.

Furthermore, at least two sealing elements may be utilized on the at least one connector assembly to seal the at least one connector assembly against the housing of the filter assembly to ensure a desired and/or optimal oil flow between the oil filter arrangement and the vehicle.

Further, the oil filter arrangement may be centered with the at least two sealing units inside the oil filter arrangement housing.

The sealing element may be an annular sealing element, for example, the annular sealing element may be an O-ring or a similar annular sealing element.

In an implementation, the oil of the vehicle may be pumped and/or pressed by the separate oil pump unit from the outlet pipe into the inlet pipe so that it may be transferred from the outside of the at least one filter unit to the inside of the at least one filter unit and from the inside of the at least one filter unit via the at least one radial hole sideways out of the at least one connection unit into the at least one radial groove and the oil filter arrangement housing.

In other words, the oil may be led out of a center tube of the at least one filter unit towards the oil filter arrangement housing.

In an implementation, the oil filter arrangement may be configured to be fixed in the oil filter arrangement housing by means of a force-locking connection with the separate oil pump.

In other words, the at least one oil filter may be held without any joints, such as screw joints.

In an implementation, the connection unit and the filter unit may be detachably connected with each other.

In addition, the oil filter arrangement may be configured to separately replace the at least one connection unit and/or the at least one filter unit with respect to each other.

A further aspect of the present disclosure relates to an oil pump and oil filter arrangement for pumping and filtering oil of a vehicle, comprising:

• • a disclosed oil filter arrangement for filtering the oil; and
  • an oil pump unit for pumping the oil comprising an outlet tube;
  • whereby the oil filter arrangement and the oil pump unit are connected to each other to transfer the oil between the oil pump unit and the oil filter arrangement at least from the outlet tube to the inlet tube;
  • whereby the oil filter arrangement is configured to be housed in an oil filter arrangement housing of the vehicle.

Therefore, the advantage may be that the oil pump and oil filter arrangement may be configured to be housed in the oil filter arrangement housing of the vehicle which may improve the installation of the oil pump and the oil filter arrangement, especially the installation of the oil filter arrangement in such a way that it may be installed without fasteners and without a sealing interface to the outside environment. In this case, the oil pump unit may provide the sealing to the outer environment, while the oil filter arrangement is sealed with at least two sealing elements against the oil filter arrangement housing, so that even a leak from the oil filter arrangement may not be critical since it is in the oil filter arrangement housing, where a wet or humid environment may be.

In an implementation, the oil pump and oil filter arrangement may comprise an oil strainer unit be configured to filter the oil transferred between the vehicle and the oil pump unit.

In an implementation, the oil filter arrangement and the oil pump unit may be arranged coaxially to each other.

In other words, the oil filter arrangement and the oil pump unit may be positioned coaxially to each other.

In an implementation, the oil pump unit may comprise at least one contact element which may be configured to be in contact with at least one contact element of the at least one connection unit.

In other words, to lock the oil filter arrangement, the oil pump unit will get in touch with the oil filter arrangement when the oil pump unit being assembled. The oil filter arrangement and the oil pump may be contacted with each other by means of respective contact pads.

Further, after insertion into the oil filter arrangement housing, the oil filter arrangement may have only one degree of freedom of movement in the axial direction, and the degree of freedom of movement may be restricted by the oil pump unit.

A further aspect of the present disclosure relates to a vehicle with an oil pump and/or an oil filter arrangement, whereby at least the oil filter of the arrangement is housed in an oil filter arrangement housing of the vehicle. The oil pump and oil filter arrangement may be housed in a housing of the vehicle.

This may provide the advantage that the oil filter arrangement does not have to be held in place by a fixing feature, but rather by the oil pump unit. This also allows that some oil channels in the housing of the vehicle may be skipped.

Therefore, the oil pump unit may be installed after the oil filter arrangement. Thereby, the oil filter arrangement may be in a centered and/or in a fixed rotational position in the oil filter arrangement housing. In this case, the position of the oil filter arrangement may be correctly held in position by, for example, holes and projections.

In an implementation, the oil filter arrangement housing may be provided in at least one axle, at least one engine housing and/or at least one transmission housing of the vehicle.

The at least one axle may be an electric axle of the vehicle, preferably the at least one axle may be an electric drive axle of the vehicle. The electric axle and/or the electric drive axle of the vehicle may comprise at least some components for electrically driving the vehicle, whereby the electric drive axle may comprise all components for electrically driving the vehicle.

Further, the at least one engine housing and/or the at least one transmission housing may comprise a flange for connecting the oil pump to the at least one engine housing, the at least one transmission housing and/or the at least one axle of the vehicle.

The oil filter arrangement housing may be in an oil sump.
