20090057969 | Strut for a Wheel Suspension of Motor Vehicles - The invention relates to a strut for a wheel suspension of motor vehicles, comprising a telescoping shock absorber and a support spring which surrounds it, as well as with a vertical adjustment means with a driven driving spindle which is pivoted by way of a body-mounted bearing on the engine housing side, which interacts with a vertically adjustable lifting element which is arranged to be non-rotatable and which bears the spring plate of the support spring. According to the invention, the driving spindle, in addition to the body-mounted bearing, is supported directly or indirectly on the cylinder tube of the shock absorber to be able to pivot and move axially relative to it. | 03-05-2009 |
20100181709 | ADJUSTABLE BLOW-OFF SUSPENSION - Altering the damping rate of a vehicle suspension damper. A pressure of a damping fluid is exerted against a second valve mechanism connected to the vehicle suspension damper. The pressure of the damping fluid is increased beyond a threshold of the second valve mechanism that is adjustable by an adjustment member. The adjustment member is exposed through a high pressure side of the vehicle suspension damper. The second valve mechanism is then opened. | 07-22-2010 |
20100252972 | METHODS AND APPARATUS FOR SELECTIVE SPRING PRE-LOAD ADJUSTMENT - A method and apparatus for a suspension comprising a spring having a threaded member at a first end for providing axial movement to the spring as the spring is rotated and the threaded member moves relative to a second component. In one embodiment, the system includes a damper for metering fluid through a piston and a rotatable spring member coaxially disposed around the damper and rotatable relative to the damper. | 10-07-2010 |
20100308518 | Spring Strut Arrangement for Wheel Suspension of Motor Vehicles - The invention relates a spring strut arrangement for wheel suspensions of motor vehicles, which is formed from a telescoping shock absorber, a suspension spring element which is preferably made as a helical compression spring, and a preloaded spring element which is preferably made as a helical compression spring, the spring elements being supported by way of spring caps on the body of the motor vehicle and on a wheel suspension element and a third spring cap located in between being movably guided along the longitudinal axis of the shock absorber relative to the body by way of an electrically driven positioning drive which is located within the spring elements, the positioning drive having a positioning spindle which is pivoted around the shock absorber and an adjusting nut which is connected to the movable spring cap. According to the invention, the shock absorber with the shock absorber tube is located at the top on the body of the motor vehicle and the positioning spindle is pivoted on the shock absorber tube. | 12-09-2010 |
20140197586 | DAMPING DEVICE WITH ADJUSTABLE SPRING RATE - A spring and damping device for a wheel suspension in motor vehicles includes an upper region, a lower region, and a damping element arranged between the upper region and the lower region. The device further includes a coil spring element and a rubber spring element. The coil spring element and the rubber spring element are arranged one behind the other along a center axis of the damping element such that the coil spring element is positioned to exert a force on the rubber spring element. The device allows a spring rate to be adjusted based either on sensed conditions, or by driver input. The spring rate may be adjustable between discrete settings or continuously variable. | 07-17-2014 |
20140265080 | SUSPENSION WITH HYDRAULIC PRELOAD ADJUST - A shock absorber for a vehicle having a damper and a first and second springs mounted coaxially around the damper and a preload adjuster for partially compressing at least one of the springs independently of the compression stroke. In one embodiment the preload adjuster is remotely controllable. In another embodiment the shock absorber includes an additional mechanism for preloading at least one of the springs. | 09-18-2014 |
20150097323 | PRESSURE SHOCK ABSORBER AND VEHICLE SUSPENSION INCLUDING THE SAME - A pressure shock absorber includes: a spring portion used for a vehicle suspension; a hydraulic jack portion which can adjust a preload of the spring portion; and a connecting portion through which a hydraulic pressure source supplying hydraulic pressure to the hydraulic jack portion is connected to the hydraulic jack portion, in which the connecting portion can be connected to and separated from the hydraulic pressure source. | 04-09-2015 |
20160129750 | SUSPENSION WITH HYDRAULIC PRELOAD ADJUST - A shock absorber for a vehicle having a damper and a first and second springs mounted coaxially around the damper and a preload adjuster for partially compressing at least one of the springs independently of the compression stroke. In one embodiment the preload adjuster is remotely controllable. In another embodiment the shock absorber includes an additional mechanism for preloading at least one of the springs. | 05-12-2016 |
20160159191 | LINEAR ACTUATOR TO ADJUST THE VERTICAL POSITION OF A SPRING OF A DAMPING UNIT AND VEHICLE SUSPENSION SPRING AND DAMPER UNIT AND VEHICLE COMPRISING SUCH A SUSPENSION SPRING ACTUATOR - A damper with a cylinder and a rod, a spring arranged around the damper and a linear actuator arranged to change in a controlled manner the axial position of a bottom end of the spring relative to the cylinder of the damper. The actuator comprises an inner cylindrical element arranged to be mounted around the cylinder of the damper, an outer cylindrical element, which is mounted so as to be axially slidable relative to the inner cylindrical element and is arranged to support the bottom end of the spring, and a working chamber arranged to be filled with a fluid under pressure to adjust the axial position of the outer cylindrical element relative to the inner cylindrical element. The working chamber is delimited, both radially and axially, only by the inner cylindrical element and by the outer cylindrical element. The outer cylindrical element is provided with a support flange arranged to support the bottom end of the spring. | 06-09-2016 |
