Embodiment Construction

[0040] In the different figures, identical components are always given the same reference numerals, so they are usually also described only once.

[0041] figure 1 A rear view of a tilting vehicle 1 according to the invention is shown when cornering. A tilting vehicle 1 comprises an axle 2 (which may be a steered or unsteered front or rear axle), two wheels 3, 4 placed next to each other are movably arranged on a structure 5 of the vehicle. In particular, the structure 5 of the vehicle can also support the driver and further payload.

[0042] in such as figure 1 making the turn shown, the left bend is being traversed. The tilting vehicle 1 incorporates tilting technology according to which the wheels 3 , 4 can be individually deflected along the vertical axis (Z-axis) of the vehicle's structure 5 . During this time, the wheel 3 on the outside of the curve is deflected downwards and the wheel 4 on the inside of the curve is deflected upwards. Thus, it is possible to tilt t...

Abstract

The disclosure concerns a tilting vehicle(1) with at least one multi-wheel axle(2), a vehicle structure(5) and a control unit(6) that is arranged to detect a lateral acceleration(a) acting on the tilting vehicle(1) and actively adjust a tilt angle(phi) of the structure of the vehicle about the longitudinal axis(X) thereof. In order to optimize adjustment of the tilt angle in a tilting vehicle, thecontrol unit (6) is arranged to adjust the tilt angle(phi) so that in a direction of a lateral axis(Y) of the structure of the vehicle, a Y component(ay) of the lateral acceleration(a) is partially compensated by a Y component(gy) of acceleration(g) due to gravity according to a specified compensation proportion(1)K. The compensation proportion (K) increases as a function of the lateral acceleration(a) to a global maximum value(Kmax) at a first acceleration(a1), and decreases above the first acceleration(a1).

Description

technical field [0001] The invention relates to a tilting vehicle having the features of the preamble of claim 1 . Background technique [0002] When a rail vehicle turns, the lateral forces that occur cause two problems. First, the vehicle must be prevented from traveling outside the curve or from sliding out of the curve by proper friction between the wheels and the rolling surface. On the other hand, it must be ensured that there are no tilting moments that could cause the vehicle to tip over. Considering the process in the vehicle's reference system, the centrifugal force and gravity together form a resultant force directed obliquely downward. In the case of a single-track vehicle such as a motorcycle or bicycle, the rider must ensure that he tilts the vehicle through steering or weight transfer so that the common center of gravity of the driver and vehicle lies in the direction of the resultant force relative to the wheel contact line. This corresponds to a state in ...
