Definitions

  • Air spring struts for motor vehicles have been known for some time in various embodiments. These air spring struts essentially include a piston element which is articulately connected at one end to an inner wheel support of the wheel suspension of the motor vehicle and is supported at the other end on the chassis of the motor vehicle via an air spring.
  • the air spring itself can be formed by a one-chamber system or a multi-chamber system. So-called rolling-lobe resilient members of the air spring are supported on the outer contour (wall) of a roll-off piston.
  • One-chamber systems are, for example, disclosed in German patent publications 3,624,296 and 4,213,676.
  • a roll-off piston moves within the rolling-lobe resilient member of the air spring.
  • This rolling-lobe resilient member folds over upon itself and forms the rolling lobe which, in turn, rolls off over the outer contour of the roll-off piston.
  • Multi-chamber systems have been proven for obtaining a highest possible spring action or damping.
  • a two-chamber system is known from German patent publication 2,406,835 wherein the air space, which is available, is formed by two separate air chambers which, however, are connected via throttle elements such as valves.
  • U.S. Pat. No. 5,180,145 discloses a multi-chamber system which includes an outer rolling-lobe resilient member and an inner rolling-lobe resilient member.
  • the rolling-lobe resilient members are either directed in the same direction or are directed toward each other and roll off on roll-off pistons.
  • wheel contact transverse forces which act on air spring struts, have been shown in practice to be especially disadvantageous for the support of the air spring strut as well as for the air springs thereof and these transverse forces are countered especially by the more compact configuration of the air spring struts.
  • the air spring strut of the invention is for mounting between a chassis of a motor vehicle and a wheel support of a wheel suspension.
  • the air spring strut includes: an air spring supported on the chassis and including an outer hollow cylinder and an inner hollow cylinder disposed at least partially within the outer hollow cylinder; a piston arranged within the inner hollow cylinder and connected to the outer hollow cylinder; a first rolling-lobe resilient member arranged between the outer hollow cylinder and the inner hollow cylinder so as to seal off an outer air chamber; a second rolling-lobe resilient member arranged between the inner hollow cylinder and the piston so as to seal off an inner air chamber; the inner hollow cylinder being articulately connected to the wheel support; and, the inner air chamber and the outer air chamber being arranged eccentrically to each other.
  • an air spring strut which, in an especially advantageous manner, combines a good spring action and/or damping from the multi-chamber system with an effective transverse stiffness.
  • a further advantage is that the air spring strut is built relatively short because of the guidance of the two hollow cylinders within each other and, accordingly, less structural space is needed than would be needed for conventional air spring struts having multi-chamber systems.
  • the outer hollow cylinder has a lower section having openings through which struts of the inner hollow cylinder project so as to be axially moveable.
  • the piston element is connected to the lower section of the outer hollow cylinder in a region which is located between the above-mentioned openings viewed radially. With this configuration, the air spring is configured to be especially compact.
  • openings in the lower section of the outer hollow cylinder can be virtually aligned as desired, it is preferable when these openings are arranged axially parallel to the longitudinal extension of the air spring.
  • the two air chambers are connected to each other via bores and/or valves to permit flow therebetween in order to realize a ventilation of the air volume between the two air chambers.
  • At least one spring element is arranged on the chassis of the motor vehicle and/or on the upper end of the outer hollow cylinder and/or on the upper end of the piston element to take up impact forces or to take up the maximum force when the air spring strut bottoms. It is practical that these spring elements are made of spring-elastic material.
  • FIG. 1 shows the wheel suspension of a motor vehicle having an air spring strut according to the invention
  • FIG. 2 shows a section view of the air spring strut taken along line I-I of FIG. 1.
  • FIG. 1 shows a wheel 15 which is supported on the chassis 5 of a motor vehicle by a wheel support 3 and an air spring strut having an air spring 1 .
  • a control link 4 is articulately connected to the wheel support 3 .
  • the air spring 1 is configured as a two-chamber air spring wherein two hollow cylinders ( 8 , 9 ) are arranged so as to be axially displaceable one into the other.
  • the outer one of the two air spring chambers ( 6 , 7 ) is defined by the inner wall of the outer hollow cylinder 8 and the outer wall of the inner hollow cylinder 9 . These inner and outer walls are axially displaceably connected to each other and sealed via an elastic rolling-lobe resilient member 10 .
  • the outer hollow cylinder 8 has a lower section 16 having openings 17 through which struts 18 of the inner hollow cylinder 9 are guided so as to be displaceable in the longitudinal direction.
  • the lower section 16 is, in addition, connected to a piston element 2 which projects into the upper section of the inner hollow cylinder 9 .
  • the outer wall of this piston element 2 together with the inner wall of the upper section of the inner hollow cylinder 9 define a second, inner air chamber 7 .
  • the piston element 2 and the inner hollow cylinder 9 are connected to each other so as to be axially displaceable with respect to each other by a rolling-lobe resilient member 11 which seals the above-mentioned walls.
  • these chambers ( 6 , 7 ) are connected to each other via bores and/or valves 12 so as to permit the flow of air therebetween.
  • the inner hollow cylinder 9 is so arranged axially displaceable in the outer hollow cylinder 8 that the inner hollow cylinder 9 extends into the rolling-lobe flexible member 10 of the outer hollow cylinder 8 when the air spring 1 deflects.
  • a rolling-lobe is configured with which the rolling-lobe resilient member rolls off between the wall of the outer hollow cylinder 8 and the wall of the inner hollow cylinder 9 .
  • the piston element 2 extends into the rolling-lobe resilient member 11 of the inner hollow cylinder 9 whereby a rolling lobe is likewise formed with which the rolling-lobe flexible member 11 rolls off between the wall of the inner hollow cylinder 9 and the wall of the piston element 2 .
  • the diameter d 2 of the inner hollow cylinder 9 is selected to be less than the diameter d 1 of the outer hollow cylinder 8 in such a manner that, on the one hand, the inner hollow cylinder 9 can be axially moveable in the outer hollow cylinder 8 and, on the other hand, an unhindered roll off of the rolling lobe is ensured with a correspondingly high support thereof between the two walls.
  • the same is true between the inner hollow cylinder 9 and the piston element 2 and, for an eccentric arrangement of the two hollow cylinders ( 8 , 9 ), it is important that they can move relative to each other.
  • the countering transverse force can be adjusted within defined limits by the selection of the eccentricity E shown in FIG. 2, that is, with the selection of the offset of the longitudinal axes of the two hollow cylinders ( 8 , 9 ) to each other.
  • the piston element 2 is shown as a solid piston.
  • a known shock absorber can be used whereby a so-called spring damping unit is formed which, in turn, exhibits an especially favorable spring and damping characteristics.
  • a spring element 13 is mounted on the motor vehicle chassis 5 and a spring element 14 is mounted on the piston element 2 .
  • These spring elements ( 13 , 14 ) are preferably made of a spring-elastic material. Maximal impact forces or maximal forces which occur when the air spring strut bottoms can be taken up by the spring elements ( 13 , 14 ).
