Abstract
Disclosed herein are active hydraulic cylinders for use in active vehicle suspension systems, and methods for assembling active hydraulic cylinders for use in an active vehicle suspension system. In particular, in certain embodiments a manifold may encircle a portion of an outer tube of a twin tube assembly. The manifold may mechanically and fluidly couple a pump assembly to the twin tube assembly. In certain embodiments, the manifold may be welded onto the outer tube.

A method for assembling a component for an active hydraulic cylinder, the method comprising:
- (a) inserting a first end of an outer tube through a substantially circular opening of a manifold;
- (b) aligning a first plurality of apertures in a surface that extends from the substantially circular opening with a second plurality of apertures in a wall of the outer tube;
- (c) affixing the manifold to the outer tube;
- and
- (d) attaching a pump assembly to a first mounting section of the manifold, wherein the pump assembly includes a pump and a pump housing.
A method for assembling a component for an active hydraulic cylinder, the method comprising:
- (a) inserting a first end of a body cap through a substantially circular opening of a manifold;
- (b) aligning a first plurality of apertures through a surface that extends from the substantially circular opening with a second plurality of apertures through a wall of the body cap;
- (c) affixing the manifold to the body cap;
- and
- (d) attaching a pump assembly to a first mounting section of the manifold, wherein the pump assembly includes a pump and a pump housing.
An active hydraulic cylinder, the component comprising:
- an outer tube surrounding at least a portion of a length of a pressure tube, such that an annular volume is at least partially defined by an inner surface of the outer tube and an outer surface of the pressure tube;
- a manifold surrounding a portion of the outer tube, wherein the manifold includes a series of flow channels and a first mounting section;
- and
- a pump assembly mounted onto the first mounting section of the manifold, wherein the pump assembly includes a pump housing and a pump having a first port and a second port.
