End member assemblies and travel-restraint assemblies as well as gas spring assemblies including same

An end member assembly (EMI) includes an end member body (400) and a support column (500). The end member body (400) includes an outer side wall and an inner side wall that together at least partially define an end member reservoir. The inner side wall at least partially defines a passage through the end member body. The support column (500) extends into the passage and is accessible from along opposing ends of the passage. A sealing element can be disposed in fluid communication between the end member body and the support column. An elongated gas damping passage can extend through the end member assembly in fluid communication with the end member reservoir. A gas spring assembly can include a flexible spring member (200) that at least partially defines a spring chamber with an end member (900) and the end member assembly (EMI) on opposing ends thereof. A restraining assembly (1000) can be secured within the spring chamber.

An aircraft landing gear assembly includes a mechanical structural linkage having a shock absorber and a linkage abutment which are biased apart by a mechanical spring. The force required to deform the spring sufficiently to place the linkage abutment at a predefined distance with respect to the shock absorber abutment is less than the breakout force of the shock absorber.

Pneumatically tuned vehicle powertrain mounts

A system for securing a powertrain component to a body structure of a vehicle may include first and second mounts each having a base and a first elastomeric barrier secured to and extending from the base defining an air filled chamber, and a connector coupling the air filled chambers, the connector sized to provide an associated air volume that reduces stiffness of the first elastomeric barrier at an excitation frequency corresponding to a target engine speed. The air filled chambers may be hermetically sealed and pressurized above atmospheric pressure. The system may include a fluid-filled switchable mount having a decoupler air pocket selectively coupled to a vacuum source or atmosphere with an expander integrated with the mount or as a separate component coupled between the decoupler air pocket and the vacuum source. The expander may be implemented as a Helmholtz resonator or may include an in-line expansion chamber.

HYDRAULIC SUSPENSION DAMPER WITH HYDRO-MECHANICAL STROKE STOP

A hydraulic suspension damper includes a tube having an opened end and a closed end defining a compartment. A main piston is disposed in the compartment dividing the compartment into a compression chamber and a rebound chamber. A piston rod is attached to the main piston. A rod guide is disposed at said opened end. A stroke stop arrangement includes an insert and an additional piston attached to the piston rod. The insert has a narrowed section including an inner surface defining at least one recess between the distal end and the rod guide and extends axially along the insert in fluid communication with the compression chamber for allowing working liquid flow from the rebound chamber to the compression chamber during the rebound stroke. The at least one recess includes three recesses disposed equidistantly and spaced from one another.

VEHICLE SUSPENSION SYSTEM
20180156303 · 2018-06-07 ·

A vehicle suspension system (3) includes an electromagnetic damper (7) provided with a sprung member (8) and an unsprung member (9) to apply a drive force and a damping force between the sprung member and the unsprung member, and a control unit (10) for controlling the electromagnetic damper. A target load for the electromagnetic damper is determined based on the unsprung member demand load that attenuates a vertical vibration of the unsprung member, and the sprung member demand load that restrains a vertical displacement of the sprung member. An absolute value of the sprung member demand load is reduced when a sprung member frequency is in an unsprung member resonance frequency range.

Four brakes system for the doors of excavator buckets

A brake system for the doors of excavator buckets which increases the braking force of the doors, allowing the use of heavier caps with more shield, increasing the durability and reliability, cushioning the blows of the door against the frame of the bucket and decreasing the likelihood that the whole system is deregulated at the same time.

Bearing Assembly for the Bearing of a Steering Shaft

A bearing assembly for bearing a steering shaft includes a bearing housing, a bearing, and a damping disk. The housing has two housing sections. The bearing is integrated into the damping disk. The damping disk is positioned so that an inner wall of a first housing section radially supports a circumferential side of the damping disk, and such that a second housing section is axially supported by the damping disk.

Variable load control system in a hydraulic device

A hydraulic device includes a tubular housing, inside of which a rod is jointly attached to a piston separating upper and lower areas which hold hydraulic fluid so that, as the piston and rod move, the piston and the rod move together relatively and axially inside the tubular housing, displacing the hydraulic fluid inside the tubular housing, flowing from one of the upper and lower areas to the other of the upper and lower areas, and thus changing the respective volumes inside the upper and lower areas. The hydraulic device further includes a modular mechanism located inside the lower area that regulates shock absorption at a maximum level of compression of the hydraulic device, as well as in other relative positions.

Cab suspension system for a work vehicle

A cab suspension system for a work vehicle includes a front suspension assembly having a bracket configured to fixedly couple to a frame of a cab of the work vehicle. In addition, the front suspension assembly includes a support element having a torsion bar and a pair of longitudinal supports. Each of the pair of longitudinal supports is configured to rotatably couple to a chassis of the work vehicle. The front suspension assembly also includes a damping assembly coupled to the support element and configured to couple to the chassis. The bracket is rotatably coupled to the support element at a pivot joint assembly, and the bracket is configured to position the pivot joint assembly forward of the cab relative to a direction of travel of the work vehicle while the bracket is coupled to the frame of the cab.
