Abstract

A laterally tiltable, multitrack vehicle is disclosed. The vehicle includes a vehicle body and at least three wheels, with two of the wheels being assigned to a common axle to form a first wheel pair. A first wheel control part suspends the first wheel of the wheel pair from the vehicle body and a second wheel control part suspends the second wheel of the wheel pair from the vehicle body. The first wheel control part is configured to be coupled to the second wheel control part via a first gearwheel mechanism, and the second wheel control part is configured to be coupled to the first wheel control part via a second gearwheel mechanism. The first and second gearwheel mechanisms each have a negative transmission ratio between a drive shaft and an output shaft. The laterally tiltable, multitrack vehicle may be a motor vehicle.

Claims

1. A laterally tiltable, multitrack vehicle, comprising:

a vehicle body;

three wheels;

first and second wheels of the three wheels assigned to a common axle to form a first wheel pair;

a first wheel control part suspending the first wheel of the wheel pair from the vehicle body and a second wheel control part suspending the second wheel of the wheel pair from the vehicle body;

wherein the first wheel control part is configured to be coupled to the second wheel control part via a first gearwheel mechanism, and wherein the second wheel control part is configured to be coupled to the first wheel control part via a second gearwheel mechanism, each of the first and second gearwheel mechanisms having a negative transmission ratio between a drive shaft and an output shaft.

2. The vehicle as claimed in claim 1, wherein the transmission ratio is less than −

1.

3. The vehicle as claimed in claim 1, wherein the first and second gearwheel mechanisms are planetary gear mechanisms or differential gear mechanisms.

4. The vehicle as claimed in claim 1, wherein each wheel of the wheel pair is mounted on a respective one of the first and second wheel control parts in a manner which is resilient and damped in terms of oscillations.

5. The vehicle as claimed in claim 1, wherein the first and second wheel control parts are longitudinal links.

6. The vehicle as claimed in claim 5, wherein a first end of each longitudinal link is pivotably mounted on the vehicle body and a second end of each longitudinal link is rotatably mounted on a respective wheel of the wheel pair.

7. The vehicle as claimed in claim 1, further comprising a fourth wheel, the third and fourth wheels forming a second wheel pair.

8. The vehicle of claim 7, wherein one wheel pair forms steerable front wheels and the second wheel pair forms rear wheels of the vehicle.

9. The vehicle of claim 1, wherein the vehicle is a motor vehicle.
