Abstract:
The present invention relates to a method for more efficient boarding and alighting at stops for road-based vehicles of public transport type, comprising the step of activating lowering of the vehicle for said boarding and alighting at stops, which step of activating (S1) said lowering takes place before arrival at the respective stop, on the basis of the vehicle's location and those of stops along its itinerary, so that said lowering is substantially completed for boarding and alighting there. The present invention relates also to a system (I) for more efficient boarding and alighting at stops for road-based vehicles of public transport type. The present invention relates also to a motor vehicle (1). The present invention relates also to a computer programme and a computer programme product.
Abstract:
A variable stiffness mechanism (301, 801, 1301, 1801) includes a cantilever arm (310) having a first end (313) rotatably attachable to a sprung mass (304), and having a second end (314) attachable to an unsprung mass (303); a variable strut (320) having a top (321) slidably attached to a bracket (330) and having a bottom (322) slidably attached the cantilever arm, wherein the bracket is attachable to the sprung mass; and at least one device (340) for relocating orientation of the variable strut. The variable stiffness mechanism has an effective spring constant between the sprung mass and the unsprung mass, and wherein the effective spring constant depends on a frequency of excitation of the unsprung mass. A suspension system (300, 800, 1300, 1800) includes the variable stiffness mechanism in a cooperative arrangement with a conventional spring (302).
Abstract:
An integrated manifold system 10 maximizes space for the circuit board 16 while enabling efficient control of one or more pneumatic devices. The manifold system includes a manifold block 12, a solenoid valve 8, 9 attached to the manifold block, and a circuit board for controlling the solenoid 14 and other components of an air suspension system. The manifold block includes at least one service port 22 for connecting to a pneumatic device such as an air spring, and a supply port 20 for connecting to a compressor. The solenoid valve is mounted to the manifold block with its longitudinal length being generally parallel to the service port. The circuit board is mounted adjacent to the solenoid valve and oriented generally parallel to the solenoid and service port. A cover 18 encloses the solenoid valve and the circuit board. In one embodiment, the solenoid valve is in fluid communication with the supply port. The solenoid valve is uniquely associated with the service port.
Abstract:
A connector for use in as a third point connector for a tractor has a hydraulic and pneumatic chamber for providing an easy method to adjust the length of the third point connector to thereby change the angle between the tractor and an attached implement. When a release valve is opened, the two sides of the connector can be moved towards or away from each other as air enters from the environment or exits as needed to balance the pressure inside the connector. An induced air pocket in the hydraulic chamber allows for a slight cushion against the forces as the incompressible hydraulic fluid prevents larger swings in the length of the connector. One or more of the opposing ends may have threaded connectors to allow for general size changes to the connector.

Abstract:
A method and system for adjusting a relative leveled height of a sprung mass (4) of a vehicle (2) to an unsprung mass (11, 12) of the vehicle. The method (160- 174) also includes receiving an input from an operator for incrementally/decrementally changing the height of the sprung mass. A system (1) for performing the method is also disclosed.
Abstract:
Während im Stand der Technik aktive Federsysteme mit passiven Dämpfern kombiniert werden und regelbare Dämpfer lediglich zusammen mit passiven Federsystemen eingesetzt werden, wird erfindungsgemäß ein aktives Federungssystem (18, 20, 22) mit einem zwischen zumindest zwei Einstellzuständen schaltbaren und bevorzugt vollständig regelbaren Dämpfer (24) kombiniert. Die Dämpferkennlinie kann dann passend zu einem Kraftfahrzeugzustand eingestellt werden: Im Normalfall soll das aktive Federungssystem Schwingungen eines Kraftfahrzeugsaufbaus (10) beeinflussen, bei unebener Fahrbahn (14) soll hingegen der Dämpfer (24) Radschwingungen beeinflussen.
