Spring- and damping arrangement for a motorcycle
A spring and damping arrangement for adjusting the spring rate and the driving position of a motorcycle includes a series circuit having at least one helical spring, an air spring unit, and a hydraulic actuating element. The spring rate of the air spring unit is changeable as a function of a force acting from the outside on the spring and damping arrangement, such that the driving position change resulting from the applied force is compensated by the hydraulic loading of the hydraulic actuating element, such that a defined driving position can be adjusted or maintained.
1. A spring and damping arrangement for setting a spring rate and a riding position of a motorcycle, comprising:
at least one coil spring;
an air spring unit; and
a hydraulic actuator,
wherein
the at least one coil spring, the air spring unit and the hydraulic actuator are arranged in a serial connection with the at least one coil spring at a first end of the serial connection,
a spring rate of the air spring unit is changeable based on a force which acts on the spring and damping arrangement,
the hydraulic actuator is configured to compensate a riding position change resulting from a change in the spring rate of the air spring unit by changing a hydraulic loading of the hydraulic actuator, such that the riding position is maintained or changed to a predetermined riding position.
2. The spring and damping arrangement as claimed in claim 1 , wherein
the hydraulic actuator includes a hydraulic loading changing device.
3. The spring and damping arrangement as claimed in claim 2 , wherein
the hydraulic loading hydraulic loading changing device is a mechanical or electromechanical setting apparatus.
4. The spring and damping arrangement as claimed in claim 3 , further comprising:
a movable separating piston arranged between the air spring unit and the hydraulic actuator, the movable separating piston being configured to set an air volume of the air spring unit.
5. The spring and damping arrangement as claimed in claim 4 , wherein
the air spring unit includes a connector stub configured for passage of air or a non-air gaseous medium capable of changing the spring rate of the air spring unit by changing a filling pressure of the air spring unit.
6. A motorcycle or engine-operated bicycle comprising:
a spring and damping arrangement as claimed in claim 5 .
7. The motorcycle or engine-operated bicycle as claimed in claim 6 , further comprising:
a user-operable ride level regulator of a chassis, the ride level regulator being configured to change the hydraulic loading of the of the hydraulic actuator to maintain or to change to the predetermined riding position based on one or more of a loading state of the motorcycle and a dynamic driving situation of the motorcycle.
8. The motorcycle or engine-operated bicycle as claimed in claim 7 , further comprising:
a pressure sensor system; and
a pressure display,
wherein
the pressure display is connected to the pressure sensor system such that the pressure display is capable of displaying one or more of the hydraulic loading and the filling pressure in the air spring unit.
9. The motorcycle or engine-operated bicycle as claimed in claim 8 , further comprising:
an electrically adjustable damper configured to set an oscillation behavior of the spring and damping arrangement.
10. The motorcycle or engine-operated bicycle as claimed in claim 9 , further comprising:
a stop or a rebound buffer spring connected to the air spring unit, the stop or rebound spring being configured to limit one or more of spring travel and extension force of the air spring unit during braking.
11. The motorcycle or engine-operated bicycle as claimed in claim 8 , further comprising:
a stop or a rebound buffer spring connected to the air spring unit, the stop or rebound spring being configured to limit one or more of spring travel and extension force of the air spring unit during braking.
12. The motorcycle or engine-operated bicycle as claimed in claim 7 , further comprising:
an electrically adjustable damper configured to set an oscillation behavior of the spring and damping arrangement.
13. The motorcycle or engine-operated bicycle as claimed in claim 12 , further comprising:
a stop or a rebound buffer spring connected to the air spring unit, the stop or rebound spring being configured to limit one or more of spring travel and extension force of the air spring unit during braking.
14. The motorcycle or engine-operated bicycle as claimed in claim 7 , further comprising:
a stop or a rebound buffer spring connected to the air spring unit, the stop or rebound spring being configured to limit one or more of spring travel and extension force of the air spring unit during braking.
15. The motorcycle or engine-operated bicycle as claimed in claim 6 , further comprising:
a pressure sensor system; and
a pressure display,
wherein
the pressure display is connected to the pressure sensor system such that the pressure display is capable of displaying one or more of the hydraulic loading and the filling pressure in the air spring unit.
16. The motorcycle or engine-operated bicycle as claimed in claim 15 , further comprising:
an electrically adjustable damper configured to set an oscillation behavior of the spring and damping arrangement.
17. The motorcycle or engine-operated bicycle as claimed in claim 16 , further comprising:
a stop or a rebound buffer spring connected to the air spring unit, the stop or rebound spring being configured to limit one or more of spring travel and extension force of the air spring unit during braking.
