A method for reshaping an electric drive signal of a real-time damper in a sprung mass system includes detecting a periodic frequency and magnitude of a target periodic vibration of a sprung mass. The periodic vibration has velocity and elasticity components that are 90 degrees out-of-phase. An electric drive signal to the real-time damper is reshaped by a controller depending on polarity of the velocity component to thereby generate a composite drive signal. The damper is energized using the composite drive signal to modify a damper force. Reshaping the electric drive signal includes injecting a force and/or an intermittent drive suppression component onto the electric drive signal based on the frequency and magnitude. The sprung mass system may have a frame and body, motion and wheel speed sensors, the real-time dampers, road wheels, and a controller programmed to perform the method.

A shock absorber includes: a damper tube accommodating a piston in a reciprocally movable manner; a suspension spring for urging the damper tube and a piston rod in opposite directions; a first male screw provided on an outer peripheral surface of the damper tube; a first nut screwed into the first male screw so as to enable a spring load of the suspension spring to be adjusted; a second nut screwed into the first male screw so as to enable a position of the first nut in an axial direction of the damper tube to be fixed; a second male screw having a reverse screw configuration to the first male screw and provided on the outer peripheral surface of the damper tube; and a damper head screwed into the second male screw so as to enable the damper head to cover one end portion of the damper tube.

A mounting system for the elastic mounting of a strut or a vibration damper on a vehicle body includes a unit insertable into a receiving cup and a fixing device. The unit includes a mounting unit and a piston rod of a strut or vibration damper. In embodiments, the mounting unit has an elastomer mount for mounting the piston rod; the elastomer mount has a core for receiving the piston rod and an elastomer body, and a ring element that is a separate part or is non-positively, positively and/or materially connected to the body; the unit and fixing device may be inserted into the receiving cup from a side facing away from the body; the fixing device engages behind an undercut formed on the receiving cup; the ring element is supported on the fixing device; and/or the elastomer body is prestressed and presses the ring element against the fixing device.

A vehicle weight measurement device includes a diaphragm which covers an opening area of a groove portion of a mounting part to form an oil chamber of a predetermined space together with the groove portion; a pressure sensor which detects a change in pressure of measurement fluid in the oil chamber; a first piston which presses the diaphragm; a second piston which presses the first piston; and a bearing unit interposed between the second piston and a spring bush which receives one end of a spring of a suspension device and is relatively rotatable. The bearing unit includes a thrust needle bearing which swingably supports a load in a longitudinal direction of the suspension device, and a slide bush which does not receive a load in the longitudinal direction and receives a load in a radial direction while causing constant damping to swinging.

An exemplary system for aligning a relative position between two components includes a locating member and an alignment insert member configured to couple with the locating member. The alignment insert member includes a radially-extending tab. The radially-extending tab has a plurality of identifying markers to identify a radial position of the locating member. The locating member is rotatable within the alignment insert member to adjust a radial position of the locating member.

A RevoKnuckle-type suspension for a wheeled vehicle has a hub mounted to a bearing carrier for rotation relative thereto about a steering axis, and a shock absorber connected non-rotatably to the bearing carrier. The shock absorber has an outer cylinder having an axially-extending guide hole defined therein, and a piston and attached piston rod retained for axial reciprocation in the guide hole. The guide hole and at least one of the piston and the piston rod retained therein have respective complementary-shaped, non-circular cross-sectional shapes which engage one another to resist axial rotation of the piston and/or the piston rod within the guide hole. The carrier is therefore restrained against rotation relative to the vehicle sprung structure without the need for any additional component(s) such as a control arm or stabilizer, as required in a traditional RevoKnuckle-type suspension.

A shock absorber for a vehicle may include a flow path provided in a rod valve to allow an oil film to be formed between a cylinder and the rod valve during relative movements of a strut rod and the cylinder, and the oil film is used to prevent friction from occurring between the cylinder and the rod valve during steering.

A suspension structure of a utility vehicle includes: a shock absorber; a knuckle; and an upper arm and a lower arm which connects the knuckle to a vehicle body frame of the utility vehicle, wherein a recessed portion which is recessed downward is formed on the upper arm, and a lower end of the shock absorber is supported by the recessed portion.

An assembly includes a leadscrew, a strut, and a motor. The strut is movable along the leadscrew upon rotation of the leadscrew. A camber angle of a wheel is changeable according to movement of the strut along the leadscrew. The motor is drivably connected to a rotating shaft that is mounted to the leadscrew.

Provided is a slide bearing capable of sustaining sliding performance over long period.

A slide bearing has an upper case (2) configured to be attached to an upper support for attachment of a suspension to a vehicle body, a lower case (3) rotatably combined with the upper case (2) to form an annular space (7); and an annular center plate (4) and an annular sliding sheet (5) both placed within the annular space (7). The center plate (4) includes a bearing surface (40) slidable with the sliding sheet (5) and an annular groove (42) formed on the bearing surface (40) so as to hold lubricant. The annular groove (42) has an inner circumferential surface (43a) inclining down from the opening section toward the groove bottom section as it goes outwardly in the radial direction and an outer circumferential surface (43b) inclining down from the opening section toward the groove bottom section as it goes inwardly in the radial direction. A line P of intersection between the inner circumferential surface (43a) and the outer circumferential surface (43b) is located closer to the bearing surface (40) than to a back face (41) of the center plate (4).
