Abstract
A bumper cap assembly for an electrically adjustable hydraulic shock absorber. The bumper cap assembly includes a printed circuit board assembly and a bumper cap. The printed circuit board assembly includes power drive electronics and is electrically coupled to the shock absorber. The bumper cap defined a gap, wherein the printed circuit board assembly is housed within the gap.
Claims8
A bumper cap assembly for an electrically adjustable hydraulic shock absorber, the bumper cap assembly comprising:
- an electronic isolator assembly including a printed circuit board assembly, a gasket, and an isolator, the printed circuit board assembly is arranged between the gasket and the isolator;
- and
- a bumper cap having a cylindrical body, an annular cover defining an aperture, and including an inner column extending inward from the aperture, wherein the cylindrical body, the annular cover, and the inner column define a gap, and the electronic isolator assembly is housed within the gap, wherein the bumper cap includes:
- an outer shoulder that extends along an interior surface of the cylindrical body and abuts with an end of the shock absorber, and
- an inner shoulder that is formed at an end of the column, the inner shoulder abuts with the end of the shock absorber during a loaded state of the bumper cap and defines a clearance gap with the end of the shock absorber during an unloaded state of the bumper cap.
A bumper cap assembly for an electrically adjustable hydraulic shock absorber, the bumper cap assembly comprising:
- an electronic isolator assembly including a printed circuit board assembly, a gasket, and an isolator, the printed circuit board assembly is arranged between the gasket and the isolator;
- and
- a bumper cap having a cylindrical body, an annular cover defining an aperture, and including an inner column extending inward from the aperture, wherein the cylindrical body, the annular cover, and the inner column define a gap, and the electronic isolator assembly is housed within the gap, wherein the bumper cap includes a plurality of ribs that radially extend from the column to the cylindrical body along an inner surface of the annular cover.
A bumper cap assembly for an electrically adjustable hydraulic shock absorber, the bumper cap assembly comprising:
- an electronic isolator assembly including a printed circuit board assembly, a gasket, and an isolator, the printed circuit board assembly is arranged between the gasket and the isolator;
- and
- a bumper cap having a cylindrical body, an annular cover defining an aperture, and including an inner column extending inward from the aperture, wherein the cylindrical body, the annular cover, and the inner column define a gap, and the electronic isolator assembly is housed within the gap, wherein the bumper cap defines a plurality of grooves that extend radially from the aperture along an outer surface of the annular cover.
A bumper cap assembly for an electrically adjustable hydraulic shock absorber, the bumper cap assembly comprising:
- an electronic isolator assembly including a printed circuit board assembly, a gasket, and an isolator, the printed circuit board assembly is arranged between the gasket and the isolator;
- and
- a bumper cap having a cylindrical body, an annular cover defining an aperture, and including an inner column extending inward from the aperture, wherein the cylindrical body, the annular cover, and the inner column define a gap, and the electronic isolator assembly is housed within the gap, wherein the bumper cap includes a plurality of ribs that extend longitudinally along an outer surface of the cylindrical body, such that a thickness of the cylindrical body between two adjacent ribs is less than a thickness of the cylindrical body at the rib.
A bumper cap assembly for an electrically adjustable hydraulic shock absorber, the bumper cap assembly comprising:
- an electronic isolator assembly including a printed circuit board assembly, a gasket, and an isolator, the printed circuit board assembly is arranged between the gasket and the isolator;
- and
- a bumper cap having a cylindrical body, an annular cover defining an aperture, and including an inner column extending inward from the aperture, wherein the cylindrical body, the annular cover, and the inner column define a gap, and the electronic isolator assembly is housed within the gap, wherein the bumper cap includes a rim that attaches to a groove defined around an outer surface of the shock absorber.
A bumper cap assembly for an electrically adjustable hydraulic shock absorber, the bumper cap assembly comprising:
- an electronic isolator assembly including a printed circuit board assembly, a gasket, and an isolator, the printed circuit board assembly is arranged between the gasket and the isolator;
- a bumper cap having a cylindrical body, an annular cover defining an aperture, and including an inner column extending inward from the aperture, wherein the cylindrical body, the annular cover, and the inner column define a gap, and the electronic isolator assembly is housed within the gap;
- a dirt wiper concentrically disposed with the aperture, wherein the dirt wiper seals between a piston rod extending through the aperture;
- and
- a seal disposed at an end of the cylindrical body opposite of the annular cover.
A damper system for a vehicle comprising:
- an electrically adjustable hydraulic shock absorber;
- and
- a bumper cap assembly coupled to an end of the shock absorber, and including an electronic isolator assembly and a bumper cap, wherein the electronic isolator assembly is electrically coupled to the shock absorber and is disposed between the shock absorber and the bumper cap, wherein the bumper cap includes:
- a cylindrical body, an annular cover defining an aperture, and an inner column extending inward from the aperture,
- an outer shoulder that extends along an inner surface of the cylindrical body and abuts with an end of the shock absorber, and
- an inner shoulder that is formed at an end of the column, the inner shoulder abuts with the end of the shock absorber during a loaded state of the bumper cap and defines a clearance gap with the end of the shock absorber during an unloaded state of the bumper cap.
