摘要:
A multi-point hydraulic suspension system (1) for a land vehicle has at least three individual hydraulic actuators (3, 5, 7). These three actuators (3, 5, 7) are each operatively arranged between a suspended structure and a wheeled base of the land vehicle for relative positioning one another. A common supply of pressurized fluid has a given pressure and a selectively operable pump (21) with an inlet and an outlet, for increasing the given pressure of the common supply of pressurized fluid. A fluid reservoir (35) is in selective fluid communication with the inlet of the pump. Controllable valve means (31, 33) are interposed between each of the at least three actuators and the common supply of pressurized fluid for selectively bringing each of the at least three actuators into fluid communication with the common supply of pressurized fluid in response to a control unit (41) for controlling the valve means (31, 33) and the pump (21).
摘要:
Die Erfindung betrifft ein Federungssystem, insbesondere eine Kabinenfederung mit mindestens einem Hydraulikzylinder (3). Der Hydraulikzylinder (3) weist einen Kolbenraum (12) und einen Stangenraum (11) auf. Der Hydraulikzylinder (3) steht mit mindestens einem Hydrospeicher (4) zum Einfedern und Ausfedern in Verbindung. Das Federungssystem weist eine Verzweigung (15) auf zur Aufteilung eines Fluidstroms (13). Der Fluidstrom (13) aus dem Kolbenraum (12) teilt sich beim Einfedern in einen Teilstrom (16) auf, der zu einem Stangenraum (11) fließt, und einen Teilstrom (17), der durch ein Drosselventil (19) zu einem Hydrospeicher (4) fließt.
摘要:
A suspension system having a piston platform that supports an air spring. The piston platform may be pivotally mounted to an upper control arm. The upper control arm may be pivotally mounted to a subframe. The piston platform may rotate with respect to the upper control arm when the upper control arm rotates with respect to the subframe.

A hydraulic shock absorbing apparatus for a vehicle includes a body left-side front wheel (7) (first traveling member) and a body right-side front wheel (8) (second traveling member), a left-side arm (11) (first connecting member) and a right-side arm (12) (second connecting member), and hydraulic shock absorbers (4, 5) provided between a vehicle body (3) and the left- and right-arms (11, 12). One end portion of each hydraulic shock absorber (4, 5) is formed by a cylinder main body (15) partitioned into a first oil chamber (21) and a second oil chamber (22) by a piston (23). The other end portion of the hydraulic shock absorber (4, 5) is formed by a piston rod (16) having the piston (23). The apparatus also includes a reserve tank (6) connected to one hydraulic shock absorber (4) via a first hydraulic oil passage (61) and connected to the other hydraulic shock absorber (5) via a second hydraulic oil passage (62). The first hydraulic oil passage (61) and the second hydraulic oil passage (62) are individually connected to a third oil chamber (57) of the reserve tank (6). It is possible to provide the hydraulic shock absorbing apparatus for the vehicle which can suppress a change in attitude of a vehicle body without increasing inclination of the vehicle body when the pair of hydraulic shock absorbers operate in the opposite directions while adopting an arrangement that can be readily manufactured.

The hydraulic stop member comprises: a cup-shaped body mounted in a compression chamber of the shock-absorber. A piston is mounted at an end of a rod of the shock-absorber so as to slide in the cup-shaped body when the shock-absorber is close to an end-of-travel position of the compression stroke. The cup-shaped body includes a side wall and a bottom wall which define, along with the piston, a working chamber where a damping fluid of the shock-absorber is compressed by the piston. A bypass conduit connects a working chamber with the portion of the compression chamber placed above a seal ring. A pressure relief valve keeps the bypass conduit closed as long as the pressure in the working chamber remains below a given threshold value and to open the bypass conduit, thereby allowing the discharge of the damping fluid from the working chamber to the compression chamber through the bypass conduit, when the pressure in the working chamber exceeds the threshold value.

Provided is a damper control device that exerts appropriate damping force to improve ride quality in a vehicle even when the vehicle gets over a projection on a road surface. In order to achieve the above object, the damper control device E1 according to the solutions to the problems of the present invention includes a correction unit 3 that corrects the damping force of a damper D based on information from which a temporal variation amount εv of a damper velocity Vd of the damper D can be grasped and level information I** from which a damping force characteristic level that is the magnitude of a damping force characteristic of the damper D can be grasped. The damper control device E1 can suppress occurrence of distortion in a characteristic of transmission damping force regardless of the magnitude of the damping force characteristic level, and does not cause a lack of the damping force by reducing the damping force more than necessary when the damping force characteristic level is small. Therefore, the damper control device E1 exerts the appropriate damping force to improve the ride quality in the vehicle even when the vehicle gets over the projection on the road surface.
