Motor vehicle body or supporting frame comprising a vibration damping device
View Patent ↗A motor vehicle with a vehicle body, which comprises at least a pair of struts, at least one vibration-selective detection unit for detecting longitudinal stresses on the struts during operation of the vehicle, and at least one actuator for producing a force that counteracts the longitudinal stress, wherein the at least two struts are connected by a holding device, which is movably supported relative to the body, wherein a common actuator is configured for simultaneously adjusting the struts connected by the actuator.
1. Motor vehicle ( 1 ) with a vehicle body, which comprises at least a pair ( 3 ; 6 ) of struts ( 4 , 5 ; 7 , 8 ), at least one vibration-selective detection unit for detecting longitudinal stresses on the struts ( 4 , 5 ; 7 , 8 ) during operation of the vehicle, and at least one actuator ( 14 ) for producing a force that counteracts the longitudinal stress, wherein the at least two struts ( 4 , 5 and 7 , 8 ) are connected by a holding device ( 10 ), which is movably supported relative to the body, wherein a common actuator ( 14 ) is configured for simultaneously adjusting the struts ( 4 , 5 and 7 , 8 ) connected by the actuator ( 14 ).
2. Motor vehicle in accordance with claim 1 , wherein the holding device ( 10 ) is rotatably ( 12 ) supported on the automobile body.
3. Motor vehicle in accordance with claim 2 , wherein the holding device ( 10 ) comprises at least one link ( 11 ), which rotates in a middle region thereof about an axis ( 12 ) that is at least almost vertical and which is connected at end regions thereof with the struts ( 4 , 5 ; 7 , 8 ).
4. Motor vehicle in accordance with claim 1 , wherein the struts ( 4 , 5 ; 7 , 8 ) are components that are separate from the body and brace the body.
5. Motor vehicle in accordance with claim 1 , wherein struts ( 4 , 5 ; 7 , 8 ) extend from outer peripheral areas of the body to a central region of an underbody ( 2 ).
6. Motor vehicle ( 1 ) with a supporting frame, which comprises at least one pair ( 3 ; 6 ) of struts ( 4 , 5 ; 7 , 8 ) and to which are assigned at least one vibration-selective detection unit for detecting longitudinal stresses of the struts ( 4 , 5 ; 7 , 8 ) during operation of the vehicle and at least one actuator ( 14 ) for producing a force that counteracts the longitudinal stress, wherein the at least two struts ( 4 , 5 ; 7 , 8 ) are connected by a holding device ( 10 ), which is movably supported relative to the supporting frame, wherein a common actuator ( 14 ) is configured for simultaneously adjusting the struts ( 4 , 5 ; 7 , 8 ) connected by the actuator ( 14 ).
7. Motor vehicle in accordance with claim 1 , wherein a common vibration-selective detection unit is assigned to the holding device ( 10 ) for each pair ( 3 ; 6 ) of struts ( 4 , 5 ; 7 , 8 ).
8. Motor vehicle in accordance with claim 1 , wherein the common actuator ( 14 ) is designed with several parts and has partial parts thereof ( 14 a ; 14 b ) that can move relative to each other.
9. Motor vehicle in accordance with claim 1 , wherein the detection unit includes a tension/pressure converter.
10. Motor vehicle in accordance with claim 1 , wherein the actuator ( 14 ) includes a pressure/tension converter ( 15 ).
