  • Patent number: 11345431
    Abstract: A front fork for a vehicle comprises a telescopic fork leg having an outer tube and an inner tube telescopically arranged relative each other. A main piston arrangement in the inner tube regulates a damping fluid for damping movements between two parts of the vehicle. The telescopic fork leg comprises a pressurizing piston arranged in the inner tube and configured to pressurize the damping fluid. The pressurizing piston comprises an axial first end portion facing the main piston arrangement an axial opposite second end portion facing a pressurized volume. A fluid reservoir for holding a pressurized fluid is fluidly coupled to the pressurized volume. The pressurizing piston is coaxially arranged with the main piston arrangement, inside the inner tube. The fluid reservoir is at least partly arranged on an outside of the inner tube. Also, a front fork and a vehicle having fork legs according to above are described.

  • Publication number: 20200094913
    Abstract: The invention relates to a telescopic fork leg for a front fork of a vehicle, comprising an outer tube and an inner tube being telescopically arranged relative each other, and a main piston arrangement arranged in the inner tube configured to regulate a damping fluid for damping movements between two 5 parts of the vehicle when in use. Further, the telescopic fork leg comprises a pressurizing piston arranged in the inner tube and configured to pressurize the damping fluid, the pressurizing piston comprising an axial first end portion facing the main piston arrangement, and further comprising an axial opposite second end portion facing a pressurized volume. Further, the telescopic fork 10 leg comprises a fluid reservoir for holding a pressurized fluid, the fluid reservoir being fluidly coupled to the pressurized volume.

  • Patent number: 9409588
    Abstract: A device adjusts the rotational damping of a steering device such that the rotational damping varies depending on whether the rotational motion about a steering axis is caused by a force acting on the steering device of the vehicle or a force acting on the part(s) of the vehicle contacting the ground. The flow of hydraulic fluid in the steering damper partly or wholly is adjusted by a main valve unit that is coupled together with both an attaching part and a steering device. The opening area of the main valve unit is determined by a relative motion between the attaching part and the steering device such that the flow of the hydraulic fluid in a direction from and to the respective damping chambers of the steering damper is controlled depending on the cause of the rotational movement.
