A substantially tubular sleeve is arranged in a damping space of the damper containing a damping fluid and has at least one recess at least in an inner face of the sleeve. The recess defines a flow channel for the damping fluid for adaptation of the flow impedance (F) for the damping fluid at least in a direction along a longitudinal axis (LA) of the sleeve. The sleeve is rigidly and releasably connected to the outer body by a number of contact surfaces on an outer surface of the sleeve and/or has at least one guide surface arranged on an inner surface of the sleeve for guiding the piston over the travel path (H).

Also disclosed is a system for modular assembly of a plurality of dampers, method of manufacture for a sleeve, and a method of production for a damper.

A suspension system includes a first compression chamber and a second compression chamber with a damping chamber therebetween. The compression chambers may be independently filled with a compressible fluid, and the relative pressures may govern the rebound rate of the suspension. Seals that minimize friction, an adjustment system, and a stop are also included to enhance rider joy.

A multi-mode air shock is disclosed herein. The air shock includes an air spring having a primary air chamber, and a damper having an insertion end to telescope within the primary air chamber and a coupler to couple with a portion of a vehicle. An adjuster housing is fixedly coupled to an end of the air spring opposite of the damper, the adjuster housing having a secondary air chamber in communication with the primary air chamber and a mounting structure to couple with a different portion of the vehicle. There is a bulkhead with a valve to open or close the fluid communication between the primary air chamber and the secondary air chamber. The air shock also includes a tertiary air chamber in fluid communication with the secondary air chamber but not in fluid communication with the primary air chamber except via the secondary air chamber.

A chassis system for commercial vehicles includes a trailing arm and a plunger piston which are connected or can be connected to one another via a connecting region, the connecting region having an adjusting device which includes an engagement element and a guide element, and it being possible for the engagement element to be moved relative to the guide element in such a way that a displacement, in particular a translational movement, of the plunger piston relative to the trailing arm is made possible.

Disclosed is a panel that is produced by assembling a plurality of adjacent individual absorption blocks; each block in the panel is in the shape of a polyhedral pyramid frustum, of which the base is a regular six-sided polygon; each individual block including six lateral walls surrounded by a lower peripheral lip of which each section is provided with a complementary tenon or a mortise arranged so as to allow two adjacent individual blocks to be assembled, in particular by engagement, in the vertical direction, of a tenon and a mortise belonging respectively to one and the other of the two adjacent individual blocks.

The present invention relates to a removable insert system (R) for a telescopic fork leg (1) of a bicycle, said telescopic fork leg (1) comprising outer and inner legs (1b, a), wherein said removable insert system comprises a piston and piston rod arrangement (6, 8) comprising a piston rod (8) arranged at least partly within a first tube (7), said removable insert system (R)being removably arranged within at least one of said inner legs (1a) such that, when being mounted in said inner leg, the removable insert system is adapted to form a damping system (D) with said inner leg, and wherein said inner leg and said first tube are both acted upon by a flow of medium created by compression and expansion movements of the fork legs, said damping system further comprising medium flow passages (C1, C2) that are parallel in relation to each other, and that run between the upper and lower sides of said piston (6)The invention also relates to a damping cartridge kit (DC) for upgrading a telescopic fork leg of a bicycle, said cartridge kit comprising a removable insert system (R).

A vibration damper for a chassis of a vehicle including a damper tube which is filled at least partially with damping liquid and in which a piston rod can be moved to and fro. A working piston is movable with the piston rod, by way of which working piston the interior space of the damper tube is divided into a piston rod-side working space and a working space which is remote from the piston rod. At least one additional attachment unit is connected to the damper tube in a fluid-tight manner by way of a throughflow element. The throughflow element is arranged on the damper tube in a direction which differs from the radial direction of the damper tube.

A hydraulic body mount with a combined rubber cushion and a hydraulic module may include an inner shaft, a mounting plate, a mounting bracket, a main rubber element, an inner ring, a fluid track, an upper bellows, a washer, a lower bellows, an outer can, a rate plate, a lower bushing, a crash washer, a doubler plate, and a retainer bracket. The fluid track may be configured to receive a fluid via a fluid port. The upper and/or lower bellows may be configured to interact with the fluid. The rate plate may be configured to engage the lower bushing and may be deformed when receiving the at least a portion of the inner shaft.

An air spring connecting device for mounting an air spring strut on a vehicle may include an air spring support bearing having a head bearing receiver, a head bearing having at least one cylindrical outer surface, and a piston rod that is axially guided through the head bearing and is sealed in an airtight manner relative to the head bearing. The head bearing may be positioned in the head bearing receiver of the air spring support bearing positioned coaxially relative to the piston rod. An airtight connection may be formed between the head bearing receiver and the head bearing. A press connection element may be positioned in direct contact with the head bearing receiver and the head bearing. A sealing element may be positioned in a region of the head bearing receiver between the air spring support bearing and the head bearing.

A viscous torsional vibration damper has an annular damper housing, which bounds a damper chamber; an inertia ring arranged in the damper chamber; a bearing device, which supports the inertia ring in the damper housing and which has one or more bearing elements, wherein at least one of the bearing elements is designed as a ring that is not circumferentially closed in a mounted state; a shear gap between the inertia ring and the damper housing, which shear gap is filled with a viscous fluid. The at least one bearing element designed as a ring that is not circumferentially closed is cut to length from a strip. In order to produce the bearing element, a strip is provided, on which one or more axial bearing sections and one or more radial bearing sections and preferably one or more webs are formed. Then, the bearing element is cut to length from the provided strip and the bearing element that has been cut to length is inserted into an open damper housing and laid on a bearing seat.
