| 20090120749 | Vibration damper and method for the production of a three-pipe system for a vibration damper - A hydraulic vibration damper has an inner pipe, a center pipe, and an outer pipe. A piston on a piston rod is guided to be displaceable in a working space that is formed by the inner pipe. Flow spaces that are hydraulically separated from one another and connected with a valve module are formed between inner pipe and center pipe. The center pipe has a radially projecting formed-out part, at which the center pipe is connected with the outer pipe or the inner pipe, via a press fit. The passage openings of the center pipe and of the outer pipe are disposed in the region of the formed-out part. Also, a separation system for hydraulic separation of the flow spaces is situated in the region of the formed-out part. Also provided is a method for the production of a three-pipe system for a vibration damper. | 05-14-2009 |
| 20120024647 | CYLINDER APPARATUS, METHOD FOR MANUFACTURING THE SAME, AND SHOCK ABSORBER - The present invention provides a cylinder apparatus processing method capable of preventing a base shell from bending which otherwise would be caused due to a residual stress generated when the base shell is processed. The cylinder apparatus processing method comprises securely holding an outer diameter of the base shell | 02-02-2012 |
| 20090145709 | SHOCK ABSORBER - Disclosed herein is a shock absorber for damping vibration transmitted to a vehicle according to a road state. The shock absorber includes a cylinder and a piston valve disposed within the cylinder and connected to a piston rod to divide the cylinder into a first chamber and a second chamber. The shock absorber further includes a hollow chamber formed within the piston rod, a floating piston disposed within the hollow chamber to move up and down and to divide the hollow chamber into upper and lower chambers, first and second orifices formed in upper and lower ends of the hollow chamber and connected to the first and second chambers, respectively, and a resistance changing mechanism configured to cooperate with the floating piston and change a fluid resistance with respect to the floating piston where the resistance changing mechanism cooperates therewith. | 06-11-2009 |
| 20110056785 | Vibration Damper - A vibration damper including a cylinder with a cylinder-side connection member. The at least one mounted component is fastened to the cylinder by a material bond. The cylinder and the mounted component are made of plastic. The mounted component and/or the cylinder are based on at least one ready-prepared semi-finished product that forms the surface of the vibration damper on at least one body side in the final state. Plastic supplemental volume fractions determine the finished body contour. | 03-10-2011 |
| 20110162928 | Super-Compressible Piston Shock Absorber - Piston-in-cylinder type shock absorbers are disclosed that are compressible to less than half of their extended length, thereby eliminating the current need for automotive suspensions to accommodate unwieldy shock absorbers that, even when fully compressed, must be longer than the amount of permitted axial suspension travel at the shock absorber's connection point. Since the disclosed shock absorbers are super-compressible, they are also super-extendable, which is extendable beyond double their compressed length. In some embodiments, this super-compressibility and super-extendibility are rendered possible by the use of a rigidly interleaved, oppositely-oriented, axially-balanced, free-floating bank of gas-charged cylinders. | 07-07-2011 |
| 20100206676 | SHOCK ABSORBER HOUSING - A shock absorber housing for a shock absorber of a vehicle comprises a tube, which has a tubular wall, and an attaching element joined onto the tubular wall, the attaching element determining a critical force introduction area of an introduction of a force into the tubular wall, the tube in a longitudinal direction being built up from a first tube section having a first tubular wall and at least a second tube section having a second tubular wall, the first tube section and the second tube section being joined together by their ends facing one another. The first tube section and the second tube section are joined together with a tubular wall overlap of the first and second tubular wall, which overlap extends in a longitudinal direction, the tubular wall overlap being situated in the critical force introduction area of the attaching element. | 08-19-2010 |

| 20080236969 | HYDRAULIC CYLINDER LIMITER - A limiter bracket, for restricting the stroke of a hydraulic cylinder, is formed from a U-shaped member having a central base portion and two opposing sidewall. The base has a semi-circular retention slot extending from an off center position centrally located detent within the base. The opening of the slot is asymmetrically located at an off center position along an edge of the base so that the rod of a cylinder is both horizontally and vertically displaced during positioning within the limiter. Once the rod is located in the detent of the limiter, a pivot pin is inserted through a connector at the end of the rod and the aligned attachment holes in the sidewalls securing the limiter to the rod. The end of the cylinder body will contact the base of the limiter during retraction of the rod thus limiting the overall stroke of the cylinder. | 10-02-2008 |

| 20100193310 | YAW DAMPER WITH PUMP - Yaw damper for damping yaw motions between two vehicle parts. This includes in the customary manner a piston part and a cylinder part, wherein that piston part is provided with a piston which divides that cylinder part into two chambers. Between these two chambers, connecting lines are present. The embodiment of these connecting lines determines the damping characteristic which governs the motion between the piston and the cylinder part. Especially for vehicle parts which move at higher speeds and/or high frequencies, such as train sets, it is desirable to provide a damper which is as stiff as possible. For this purpose, the present invention proposes the installation of pumping elements which, as far as possible, increase the pressure in the chambers which are formed by the piston in the cylinder part. Preferably, this construction is realized such that this pressure automatically decreases at lower speeds and/or low frequencies. | 08-05-2010 |
| 20120325605 | BICYCLE WITH SUSPENSION - A bicycle can include a suspension system with a shock absorber. The shock absorber can have a sag position which can be adjustable. Sag refers to the amount of movement experienced by the suspension under a static load, such as that of the weight of a rider. Methods and systems to set sag can include at least one valve in fluid communication with a gas chamber of the shock absorber. In some embodiments, the at least one valve can be used to automatically set the sag position based on an individual's weight and riding position. | 12-27-2012 |
