Steering damper with active adjustment of damping characteristics

A device intended for a vehicle comprising:

• a steering device rotatable about a steering axis for adjusting a direction of one or more part(s) of the vehicle that are arranged for ground contacting;
• an attaching part that couples together the steering device and the one or more part(s) that are arranged for ground contact;
• and
• a steering damper comprising a delimiting part that partitions a main damping chamber that is adapted to contain hydraulic fluid and that is partitioned into a first damping chamber and a second damping chamber, wherein the attaching part rotates with the steering device and with the delimiting part, wherein a main valve unit is configured to adjust a flow of hydraulic fluid between the first damping chamber and the second damping chamber of the steering damper, the main valve unit is mechanically coupled together with both the attaching part and the steering device in order to adjust the rotational damping of the steering device, and wherein an amount of hydraulic fluid flowing through the main valve unit is determined by a relative movement between the attaching part and the steering device.

A steering damper configured to be arranged in a vehicle comprising a steering device rotatable about a steering axis for adjusting the direction of the part(s) of the vehicle configured for contacting the ground and an attaching part that couples together the part(s) arranged for contacting ground with the steering device, the steering damper comprising:

• a damping housing;
• and
• a main damping chamber defined by the damping housing, the main damping chamber comprising hydraulic fluid and being partitioned into a first and a second damping chamber;
• wherein the steering device is mechanically connectable to the attaching part to enable rotation of the attaching part with the steering device and with the damping housing, and wherein a main valve unit is configured to adjust a flow of hydraulic fluid between the first and second damping chambers in order to adjust the rotational damping of the steering device, wherein the main valve unit can be mechanically coupled with both the attaching part and the steering device, and wherein a relative movement between the attaching part and the steering device determines an amount of hydraulic fluid flowing through the main valve unit.

• wherein the steering device is mechanically connectable to the attaching part to enable rotation of the attaching part with the steering device and with the delimiting part, and wherein a main valve unit is configured to adjust a flow of hydraulic fluid between the damping chambers in order to adjust the rotational damping of the steering device, wherein the main valve unit can be mechanically coupled together with both the attaching part and the steering device, and wherein a relative movement between the attaching part and the steering device when the steering damper is arranged in a vehicle determines an amount of hydraulic fluid flowing through the main valve unit.

A crown device configured to be arranged in a vehicle comprising a steering device rotatable about a steering axis for adjusting the direction of the part(s) of the vehicle configured for contacting the ground, the device comprising:

• a steering damper having a damping housing that encloses a main damping chamber which comprises hydraulic fluid and is partitioned into a first damping chamber and a second damping chamber by a delimiting part that is disposed in the main damping chamber and moveable with respect to the damping housing;
• an attaching part configured to couple together the part(s) configured for contacting the ground with the steering device when the crown device is arranged in the vehicle, wherein the attaching part is configured to rotate with the steering device when the crown device is arranged in the vehicle;
• and
• a main valve unit configured to adjust a flow of hydraulic fluid between the damping chambers of the steering damper when the crown device is arranged in the vehicle, the main valve unit being coupled together with both the attaching part and the steering device in order to adjust the rotational damping of the steering device, and wherein the amount of hydraulic fluid flowing through the main valve unit is determined by a relative movement between the attaching part and the steering device.
