Abstract
A drive transmission includes a drive system. The drive system includes a drive unit having a drive housing. The drive system also includes a flow guide element which is mechanically fixed to the outside of the drive housing and which has at least a first cavity boundary for forming at least regions of a first fluid reservoir. A first cavity is delimited at least in regions by the first cavity boundary and is or can be fluidically connected to a lubrication device. The drive system and the drive transmission provide a means which can be used to lubricate connected or integrated transmission components in a straightforward, cost-effective, and space-saving manner.
Claims20
A drive system comprising:
- a drive unit comprising:
- a drive housing;
- and
- a flow guide element mechanically fixed on an outside of the drive housing, the flow guide element comprising:
- a first cavity boundary forming at least regions of a first fluid reservoir, a first cavity is delimited at least in regions by the first cavity boundary and is fluidically connected to a lubrication device;
- a second cavity boundary forming at least regions of a second fluid reservoir, a second cavity is delimited at least in regions by the second cavity boundary and is fluidically connected to the lubrication device, the flow guide element defining a flow channel supplying fluid into the first cavity and the second cavity, the second cavity comprising an overflow device, the fluid flowing from the second cavity into the first cavity by way of the overflow device when a limit fill level in the second cavity is exceeded;
- and
- a rib defining a flow bifurcation through an opening in the rib, the flow bifurcation formed in the flow channel for supplying fluid to the first cavity and to the second cavity.
A drive unit comprising:
- a drive housing;
- and
- a flow guide element mechanically fixed to an outside of the drive housing, the flow guide element comprising:
- a first cavity boundary forming one or more regions of a first fluid reservoir, the first cavity boundary defines a first cavity, the first cavity is fluidically connectable to a lubrication device;
- a second cavity boundary forming one or more regions of a second fluid reservoir, the second cavity boundary defines a second cavity, the second cavity is fluidically connectable to the lubrication device, the flow guide element defining a flow channel supplying fluid into the first cavity and the second cavity, the second cavity comprising an overflow device, the fluid flowing from the second cavity into the first cavity by way of the overflow device when a limit fill level in the second cavity is exceeded;
- and
- a rib defining a flow bifurcation through an opening in the rib, the flow bifurcation formed in the flow channel for supplying fluid to the first cavity and to the second cavity.
A drive system comprising:
- a transmission comprising a transmission housing and at least one cavity defined in one or more regions by a cavity boundary;
- and
- a drive unit comprising:
- a drive housing;
- and
- a flow guide element mechanically fixed to an outside of the drive housing, the flow guide element comprising:
- a first cavity boundary forming one or more regions of a first fluid reservoir, the first cavity boundary defines a first cavity, the first cavity is fluidically connectable to a lubrication device;
- a second cavity boundary forming one or more regions of a second fluid reservoir, the second cavity boundary defines a second cavity, the second cavity is fluidically connectable to the lubrication device, the flow guide element defining a flow channel supplying fluid into the first cavity and the second cavity, the second cavity comprising an overflow device, the fluid flowing from the second cavity into the first cavity by way of the overflow device when a limit fill level in the second cavity is exceeded;
- and
- a rib defining a flow bifurcation through an opening in the rib, the flow bifurcation formed in the flow channel for supplying fluid to the first cavity and to the second cavity.
