Abstract: A mounting eye (21) is fastened to a rod by pushing, partially or over an entire periphery, an outer periphery of a joint portion of a mounting eye into an annular groove of the rod. Accordingly, an axial length of a fastening portion can be set shorter than that of a related-art structure (screw fastening), thereby being capable of securing a stroke of the rod of a shock absorber in which the mounting eye is fastened to the rod.

Abstract: A method of optimizing a suspension system to avoid pitch resonance may include determining pitch characteristics of a vehicle for a terrain profile and speed range via a model associated with the vehicle, decoupling front and rear axles by removing pitch inertia from the model, and determining optimized damping for a main damper of a position sensitive damper over a linear range of wheel travel in a bounce control zone based on the pitch characteristics. The method may further include recoupling the front and rear axles by adding the pitch inertia back into the model, and selecting a secondary damper associated with a compression zone or a secondary damper associated with a rebound zone as a selected damper for adjustment based on which of the front and rear axles is limiting. The method may also include performing a damping adjustment to the selected damper and cyclically repeating selecting the secondary damper and performing the damping adjustment until pitch resonance is suppressed.

Abstract: Provided is a solenoid comprising a molded coil, an anchor, and an armature. In the anchor, an outer peripheral convex portion and an inner peripheral convex portion are formed. When no current is being applied, axial distance between the outer peripheral convex portion of the anchor and an outer peripheral portion of the armature which is radially closest to the outer peripheral convex portion is smaller than axial distance between the inner peripheral convex portion of the anchor and an inner peripheral portion of the armature which is radially closest to the inner peripheral convex portion. In other words, timing at which the outer peripheral convex portion of the anchor and the outer peripheral portion of the armature face each other in a radial direction is shifted from timing at which the inner peripheral convex portion of the anchor and the inner peripheral portion of the armature face each other in the radial direction.

Abstract: This control system comprises: a control device which, while a vehicle is driven, receives power to control the operation of a moving part and which, while the vehicle is stopped, does not receive power; and a system which is capable of communicating with the control device, and which, when the vehicle is stopped, receives power so as to be capable of ascertaining first information pertaining to time or which is capable of acquiring, during the driving, second information pertaining to times before and after when the vehicle was stopped. When the vehicle is restarted after being stopped, the control device uses at least one of the first information and the second information received from the system to ascertain the time elapsed while the vehicle was stopped, and uses the elapsed time to control the operation of the moving part.

Abstract: To provide a solenoid, a solenoid valve, and a damper in which when the amount of current supplied to the solenoid is small, the thrust of the solenoid to bias an object in one direction can be made small, and at the same time, even when the solenoid is not energized, the object can be biased in the same direction as that of the thrust. The solenoid includes a coil, a first movable iron core and a second movable iron core that are attracted in a direction away from each other by energizing the coil, a coil spring that biases the first movable iron core toward the second movable iron core, and a leaf spring that restricts the approach of the first movable iron core and the second movable iron core.

Abstract: A shock absorber includes a cylinder sealed with a working oil liquid, a piston slidably fitted in the cylinder, a piston rod connected to the piston and extended to the outside of the cylinder, and a plurality of passages through which the working oil liquid flows due to the sliding of pistons therein, and a damping force generating mechanism that is provided in a part of the passages and suppresses the flow of the working oil liquid to generate a damping force. The damping force generating mechanism includes a valve body through which the passage penetrates, an annular seat that projects from the valve body and surrounds the passage, and a disc that can be seated on the seat. A contact width at which the disc and the seat come into contact with each other is different depending on a position in the circumferential direction. As a result, it is possible to obtain a shock absorber capable of suppressing a sudden change in damping force before and after the opening of the disc valve without having a complicated structure.

Abstract: 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.

Abstract: A shock absorber system can includes a shock tube and a piston slidably mated to an end of the shock tube. The system can include a first mount on the piston for attaching to a first point on a motor vehicle. A second mount can be positioned on the shock tube near an end of the shock tube opposite the piston. The second mount can be positioned offset from an axial centerline of the shock tube. In some cases, the system can include a stabilizing device connected to the second mount. The system can include a heat sink reservoir. The heat sink reservoir can be connected to the shock tube via a valved fluid connection.

Abstract: A fluid damper assembly for use in a vehicle includes a piston subassembly which includes a plurality of inflow passages and at least one rebound disk for restricting flow of hydraulic fluid through the inflow passages. A rod extends through the piston subassembly to actuate the piston subassembly between a rebound stroke and a compression stroke. An actuator supported by and within the rod includes a piezoelectric device and an amplifier for adjusting the damping force during the rebound stroke, thereby adjusting the suspension of the vehicle. A shaft within the rod is connected to a retainer to transmit motion from the amplifier to compress a spring and disengage the retainer from the rebound disk to allow the rebound disk to flex solely in response to hydraulic fluid pressure from the rebound stroke to open the inflow passages and reduce the damping force during the rebound stroke.

Abstract: The hydraulic shock-absorber comprises a hydraulic stop member having a cup-shaped body, which is adapted to be mounted in a compression chamber, and a plunger, mounted at an end of a rod of the shock-absorber so as to slide in the cup-shaped body when the shock-absorber moves towards the compression end-of-travel position. The cup-shaped body comprises a side wall and a bottom wall which define, along with the plunger, a working chamber in which a damping fluid of the shock-absorber is compressed by the plunger when the latter slides in the working chamber towards the bottom wall of the body. Axial channels are formed on the inner surface of the side wall of the body and allow the damping fluid to flow axially out of the working chamber when the plunger slides in the working chamber towards the bottom wall of the cup-shaped body. The axial channels extend parallel to a longitudinal axis (z) of the cup-shaped body and have a cross-section whose area decreases continuously along this axis (z) towards the bottom wall of the cup-shaped body.
