SYSTEMS FOR A HYDRAULIC UNIT
Methods and systems for a hydraulic unit. In one example, a hydraulic unit includes a torque sensor external mounted to a housing of the hydraulic unit, wherein a torque sensor mount is physically coupled to a planar portion of the housing near a flange through which a drive shaft extends.
1 . A hydraulic unit, comprising:
a torque sensor externally mounted to a housing of the hydraulic unit, wherein a torque sensor mount is physically coupled to a planar portion of the housing near a flange through which a drive shaft extends.
2 . The hydraulic unit of claim 1 , wherein the torque sensor extends along an axis misaligned with each a plurality of fasteners that extend through the flange.
3 . The hydraulic unit of claim 1 , wherein the planar portion of the housing is integral with a cylindrical portion of the housing.
4 . The hydraulic unit of claim 1 , wherein the torque sensor is closer to a first end of the housing through which the drive shaft protrudes than a second end of the housing opposite the first end.
5 . The hydraulic unit of claim 1 , wherein the torque sensor is configured to sense a deformation of a surface of the housing.
6 . The hydraulic unit of claim 1 , wherein the planar portion is static.
7 . The hydraulic unit of claim 1 , wherein the torque sensor extends in a direction normal to the drive shaft.
8 . A system, comprising:
a hydraulic unit comprising a housing; and
a torque sensor comprising a mount, the mount physically coupled to a planar portion of the housing adjacent to a flange, wherein the torque sensor is misaligned with fasteners that extend through the flange.
9 . The system of claim 8 , wherein the hydraulic unit is a bent axis unit.
10 . The system of claim 8 , wherein the hydraulic unit is an axial unit.
11 . The system of claim 8 , wherein the hydraulic unit is an internal gear hydraulic unit.
12 . The system of claim 8 , wherein the hydraulic unit is an orbital hydraulic unit.
13 . The system of claim 8 , wherein the torque sensor is external mounted to the planar portion of the housing at a location proximal to a splined portion of a drive shaft.
14 . The system of claim 13 , wherein the drive shaft extends through the flange and into the housing, wherein the splined portion is arranged outside of the housing and the flange.
15 . The system of claim 8 , wherein the planar portion comprises ports configured to admit fluids into the housing.
16 . A hydraulic unit, comprising:
a torque sensor externally mounted to a housing of the hydraulic unit, wherein a torque sensor mount is physically coupled to a static element of the housing near a flange through which a drive shaft extends.
17 . The hydraulic unit of claim 16 , wherein the torque sensor mount is parallel to the static element.
18 . The hydraulic unit of claim 16 , wherein the torque sensor is physically coupled to the static element via a plurality of fasteners.
19 . The hydraulic unit of claim 16 , wherein the static element comprises a linear shape parallel to the torque sensor mount and arranged on a cylindrical portion of the housing.
20 . The hydraulic unit of claim 16 , wherein the torque sensor is positioned between a splined portion of the drive shaft and a hydraulic port of the housing.
