Abstract: A damper assembly includes an outer cylinder, an inner cylinder positioned at least partially within the outer cylinder, a cap coupled to the inner cylinder, and a plunger positioned radially inward from the inner cylinder and coupled to a rod. The plunger, the cap, and an interior of the inner cylinder at least partially define a first chamber. The suspension system further includes a passage extending through the rod and fluidly coupled with the first chamber, a piston coupled to the inner cylinder and extending radially outward toward the outer cylinder, a first port in fluid communication with the plunger through the passage, and a second port in fluid communication with the piston. The piston, an exterior surface of the inner cylinder, and the outer cylinder at least partially define a second chamber.

Abstract: A dual-mode suspension system using hydraulic dampers is disclosed. One or more dampers on each side of the four-wheel suspension system are coupled to a respective damper on the other side via a damper valve. One or more leaf springs may be arranged between the leading links coupled to some of the dampers, and trailing links coupled to other of the dampers. The suspension system may advantageously engage, lock, or partially disengage the respective dampers connected by the valve on each side of the system. Manipulating the valve to control engagement of the dampers, which may depend on the speed and related issues, provides control over whether heave motions should be separated from roll. In another embodiment, one or more single or double acting hydraulic cylinders may be used to engage dampers.

Abstract: The present invention relates to a method of controlling a variable damper in a vehicle wherein a rear-wheel variable damper can be controlled by estimating a vertical acceleration value of a rear wheel based on the fact that there is a certain time delay in a wheel motion between front and rear wheels due to the wheelbase and vehicle speed. To this end, the method of the present invention comprises the steps of (a) detecting vehicle body accelerations other than a desired vehicle body acceleration of a vehicle body; (b) calculating the desired vehicle body acceleration based on the other detected vehicle body accelerations according to a geometric rule; (c) calculating vehicle body vertical velocities by filtering the vehicle body accelerations to eliminate DC offsets therefrom and integrating the filtered accelerations; (d) detecting accelerations of front right/left vehicle wheels; (e) calculating front wheel vertical velocities by filtering the detected accelerations of the front right/left wheels to eliminate DC offsets therefrom and integrating the filtered accelerations, and then calculating accelerations of rear wheels by time delaying the accelerations of the front wheels by a time interval taken while a road input to the front wheel is delivered to the rear wheel at a vehicle speed; and (f) calculating damper velocities based on the calculated vehicle body vertical velocities and the calculated vehicle wheel vertical velocities. Accordingly, the Sky-hook determination can be more accurately made. Further, since it is not necessary to use all the four sensors, the number of parts of vehicles can be reduced when mass-producing the vehicles. Consequently, the selling prices for finished vehicles can be lowered, and thus, an unnecessary economical burden cannot be imposed on the consumers.

Abstract: Axle-chassis connecting device is particularly for a commercial vehicle having two tandem axles of the hydropneumatic suspension type. The vertical load coming from the chassis is transmitted directly to the wheels by jacks (23) without passing through the axle tanks, and is taken into account near the wheel plane by means of a multifunction part (20) which further assures, simultaneously, the connection of the axle to the chassis by a longitudinal guide rod (26) and the transmission of the braking torques coming from the braking means (35).
