An accumulator defines an accumulator volume that can be placed into communication with a spring chamber of a gas spring. A working volume of the gas spring is the sum of the spring chamber volume and the accumulator volume. The accumulator can be configured so that the accumulator volume can be selectively increased or decreased as desired, thus modifying performance of the associated gas spring.

A method for manufacturing a pressure vessel for a motor vehicle comprises the steps: providing a hollow basic body as a primary stage of the pressure vessel, wherein the basic body has an initial internal volume, and wherein the basic body has a wall, which extends fully around a longitudinal axis of the basic body, wherein the wall has an opening, which has an opening rim; providing a hollow auxiliary body, which has a base wall and a peripheral wall, wherein the peripheral wall is open on a side lying opposite the base wall; joining the auxiliary body with the basic body at the opening in the wall of the basic body, such that the pressure vessel having a desired final internal volume which is larger or smaller than the initial internal volume of the basic body is obtained. In addition, such a pressure vessel in the form of an air suspension pot of a suspension is described.

The coupling unit has a first coupling part and a second coupling part, wherein the first coupling part and the second coupling part are arranged axially offset in relation to one another. The first coupling part connects the damper output side of the first damper unit to the second coupling part. The second coupling part connects the first coupling part to the damper input side of the second damper unit.

A modular suspension buffer for vehicle has customizable hardness and height to provide various combinations of initial contact softness and non-linearly increasing resistance during compression so as to improve driving stability, loading capacity, off road performance, and/or ride comfort while extending the operational lifespan of the vehicle suspension system.

A flywheel configured to couple to a manual transmission to an unrelated vehicle engine. Also disclosed is a method for retrofitting a manual transmission with an unrelated vehicle engine. Also provided is a flywheel comprising a removable friction region and/or a removable gear portion.

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.

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 dampening engine mount configured to mount an engine to a vehicle frame includes: a first bolt receiver having a first through hole configured to receive a first bolt; a second bolt receiver having a second through hole configured to receive a second bolt; and a mass damper connector integrally connecting the first bolt receiver and the second bolt receiver, wherein the vibration dampening engine mount has a predetermined mass.

Technologies are generally described for lead-lag dampers. An example lead-lag may include a single- or two-stage floating annular ring, elastomer bearings, a tension stop, a compression stop, and a plunger/spring volume compensator. The floating annular ring(s) form orifice(s) in conjunction with the remaining damper components may provide stable performance by tracking with any center shaft misalignment during operation. The lead-lag damper may also include a secondary spring system allowing or disallowing fluid flow between chambers based on slow or sudden movement of the shaft.

Provided is a rotary damper that can be easily changed in specifications and can be improved in economic efficiency by an existing rotary damper that can be continued to be used. A rotary damper 100 includes a main housing 101. The main housing 101 includes a module mounting portions 108 for detachably mounting the other functional module 200 to 500. The functional modules 200 to 500 respectively have module rotors 206, 306, 406 and 506 which are rotationally driven by receiving a rotational driving force from the outside, and module output portions 206b, 307a, 407a and 507a formed to be connectable to a main rotor 110, in module housings 201, 301, 401 and 501. Further, the functional modules 200 to 500 include input adjustment mechanisms 205, 305, 405 and 505 having a function of changing at least one of characteristics of the rotational driving force and modes of transmission of the rotational driving force, between the module rotors and the module output portions.
