Abstract: An accumulator for a vehicle suspension damper, which includes an outer shell with an open end that connects to an accumulator port on the damper and a distal end, opposite the open end, which includes an end wall that extends radially inward to a gas charging port. A bellows assembly, which includes an annular bellows wall extending between proximal and distal plates, is positioned inside the outer shell to define a pressurized gas chamber inside the accumulator that is arranged in fluid communication with the gas charging port. The gas charging port includes a stem that extends inwardly from the end wall of the outer shell and the distal plate of the bellows assembly has an inner diameter that is received on the stem. The inner diameter of the distal plate is coupled to the stem of the gas charging port by a fixation component.

Abstract: A wheel assembly bushing for in-wheel electric motors where the bushing includes a hydraulic chamber positioned within a resilient sleeve of the bushing and a helical fluid channel that extends helically about an inner bushing member between first and second fluid channel ends, which are arranged in fluid communication with the hydraulic chamber. An outer body extends annularly about the resilient sleeve, which permits relative movement between the inner bushing member and the outer body. The fluid channel is configured to produce inertance. This inertance, when combined with other damping and stiffness effects of the wheel assembly bushing, provides phase and magnitude shifts between force and velocity, which ultimately reduce magnetic gap deformation in the in-wheel electric motor.

Abstract: A suspension system including four dampers each having a compression chamber and a rebound chamber. First and second hydraulic circuits interconnect the compression and rebound chambers of the front dampers, while third and fourth hydraulic circuits interconnect the compression and rebound chambers of the back dampers. A first longitudinal hydraulic line extends between and connects the first and third hydraulic circuits and a second longitudinal hydraulic line extends between and connects the second and fourth hydraulic circuits. A first bi-directional pump is connected in-line with a fluid distribution line that extends between and connects the first and second longitudinal hydraulic lines a can pump fluid in opposite directions through the fluid distribution line to provide active roll stiffness.

Abstract: A shock absorber for a vehicle including a pressure tube defining a fluid chamber, a piston disposed within the fluid chamber and including a fluid passage, and a valve assembly. The valve assembly includes a restriction disc, an orifice disc, a fulcrum disc, and a check disc. The restriction disc includes a first ring, a first finger, and a first orifice. The first finger covers the fluid passage. The orifice disc includes a second ring, a second finger, and a second orifice. The second finger overlaps the first finger, and the second orifice is aligned with the first orifice. The check disc includes a third ring and a third finger above the second finger. The fulcrum disc has a fourth ring. Modifying the outer diameter of the third ring and the outer diameter of the fourth ring alters a damping response of the shock absorber.

Abstract: A shock absorber for a vehicle including a pressure tube, a piston rod, and a piston assembly. The piston assembly includes a first disc, a second disc, and a piston body. The piston body includes first and second surfaces and first and second fluid passages. The piston body further includes a first circumferential land surrounding the first fluid passage and a second circumferential land surrounding the second fluid passage. The first circumferential land is located a first distance from the first surface. The first disc is selectively driven into engagement with the first circumferential land. The second circumferential land is located a second distance from the first surface. The second circumferential land is between the first surface and the first circumferential land. The second disc includes a first portion in sealing engagement with the second circumferential land and a second portion spaced apart from the piston body.

Abstract: A method for assembling a damper assembly includes securing a damper interface to an external surface of a pressure tube. The method includes securing an accumulator interface to an external surface of an accumulator tube. The method includes, after the damper interface is secured to the pressure tube and the accumulator interface is secured to the accumulator tube, securing the pressure tube to the accumulator tube by press fitting the damper interface to the accumulator interface.
