Definitions
- the invention relates to a bearing bush for a motor vehicle, comprising a sleeve and a bolt disposed within the sleeve and at least one radially disposed between the sleeve and the bolt elastomer element for damping mounting of the bolt in the sleeve, wherein the bearing bushing switchable between at least two stiffness ig keitskinn is.
- the structure and resulting operational data of bushings used in a chassis of a motor vehicle greatly affect the driving and steering characteristics of the motor vehicle. Relatively minor changes in the spring rate or stiffness of the bushings can have significant effects on vehicle characteristics such as understeer or oversteer, chassis noise, vibration, and running stiffness. Depending on the setting of the bearing bush, the motor vehicle has a relatively "soft” or a relatively “hard” running behavior.
- DE 696 22 141 T2 discloses a method of making and using a variable stiffness suspension bushing for controlling the relative movement between a suspension arm in a motor vehicle and a frame member of the motor vehicle.
- the suspension sleeve has a variable rigidity which is realized by including a magnetorheological elastomer or gel whose stiffness is variably adjustable over a wide range by a controllable magnetic field.
- the variable controllable magnetic field is generated by means of an electromagnet structure, which as part of the structure is completely integrated in a suspension bushing structure.
- the object of the invention is to provide a bearing bush for a motor vehicle whose rigidity is mechanically adjustable and thus is not based on a hydraulic or magnetorheological action principle.
- the bolt has a ball element axially between two distal ends, the ball element interacting with at least two movable ball socket elements to change the stiffness of the bearing bush.
- a ball element is formed on the bolt.
- the bearing bush is mounted in the sleeve via the at least one elastomer element.
- the bolt is connected via the at least two ball socket elements with the sleeve in a second switching position of the bearing bush. Consequently, the at least one elastomer element is bridged over the at least two ball socket elements.
- the at least two ball socket elements for increasing the rigidity of the bearing bush on the ball element come to rest.
- a load on the bearing bush guides the force into the sleeve via the bolt and the at least two ball socket elements.
- a ball joint is realized by the connection between the ball element and the at least two ball socket elements.
- the at least two ball socket elements for the stiffness change of the bearing bush are axially movable to the ball element.
- the second switching position of the bearing bush is realized by an axial approximation of the at least two ball socket elements.
- the at least two ball socket elements for the change in stiffness of the bearing bush are movable radially to the ball element.
- the second switching position of the bearing bush is realized by a radial approximation of the at least two ball socket elements.
- the at least two ball socket elements are mounted movably at least on the sleeve.
- a recess is preferably arranged on the sleeve, which is provided to guide at least the respective ball socket element.
- the at least two Kugelpfannenele- elements are stored outside the sleeve and are passed only through the sleeve to act on the ball element.
- the at least two ball socket elements are formed substantially complementary to the ball element and enclose the ball element.
- the at least two ball socket elements are adapted to the geometry of the ball element, wherein recesses are provided for the pin axis.
- a plurality of ball socket elements receive the ball element in a second switching position of the bearing bush.
- an actuator is preferably provided for moving the at least two ball socket elements. Consequently, the at least two ball socket elements are moved axially or radially via the actuator, whereby the respective stiffness level of the bearing bush is introduced.
- the actuator comprises an electric motor and a control element for controlling and regulating the rigidity of the bearing bush.
- the invention includes the technical teaching that the ball element is arranged axially between two elastomer elements.
- the two elastomeric elements are preferably annular, wherein the bolt axially through the two Elastomer elements is passed and is thus mounted radially on the two elastomeric elements on the sleeve. Axial between the two
- Elastomer elements are arranged at least two ball socket elements.
- Figure 1 is a perspective view of a suspension arm for a motor vehicle, wherein the suspension arm has a bearing bush according to the invention, a schematic sectional view illustrating the construction of the bearing bush according to the invention according to a first embodiment, a further schematic sectional view illustrating the construction of the bearing bush according to the invention according to Figure 2a, a schematic sectional view illustrating the construction of the bearing bush according to the invention according to a second embodiment, and
- FIG. 3b shows a further schematic sectional illustration for illustrating the
- a bearing bush 1 according to the invention is arranged in a designated hole 9 on a suspension arm 8.
- the suspension control arm 8 is installed in a - not shown here - chassis of a - not shown here - motor vehicle.
- On a bolt 3 of the bearing bush 1 is a - not shown here Attached - axle carrier of the motor vehicle attached.
- the suspension arm 8 has a further bore 9a, in which a mechanical, non-switchable bearing bush 1 a is arranged.
- the bearing bush 1 a is designed as a conventional rubber bearing.
- At a bolt 3a of the bearing bush 1 a is a - not shown here - arranged wheel carrier.
- the bearing bush 1 has a sleeve 2 and a bolt 3 arranged inside the sleeve 2. Furthermore, two elastomer elements 4a, 4b are arranged radially between the sleeve 2 and the bolt 3 for damping mounting of the bolt 3 in the sleeve 2.
- the bolt 3 has axially between two distal ends of a ball element 5, wherein the ball member 5 cooperates to the stiffness change of the bearing bush 1 with three radially movable ball socket elements 6a-6c. Consequently, the ball element 5 is arranged axially between two elastomer elements 4a, 4b.
- the bearing bush 1 In the first switching position shown here, the bearing bush 1 according to the invention has a minimal rigidity. Because the bolt 3 is over the two
- Elastomer elements 4a, 4b connected to the sleeve 2 damping.
- a radial merging of the ball socket elements 6a-6c leads in a second - not shown here - switching position to a rigidity increase of the bearing bush. 1
- the bearing bush 1 is switchable between two levels of rigidity.
- the ball socket elements 6a-6c are movably mounted on the sleeve 2 for radial displacement.
- the bearing bush 1 comprises a sleeve 2 and a bolt 3 arranged inside the sleeve 2. Furthermore, two elastomer elements 4a, 4b are arranged radially between the sleeve 2 and the bolt 3 for damping mounting of the bolt 3 in the sleeve 2.
- the bolt 3 has axially between two distal ends of a ball element 5, wherein the ball member 5 for Stiffness change of the bearing bush 1 with two axially movable ball socket elements 6a, 6b cooperates.
- the two ball socket elements 6a, 6b are divided substantially in half and have for the homogeneous distribution of force on three radial elements 10a-10c, which are formed star-shaped.
- an actuator 7 is connected to the two ball socket elements 6a, 6b.
- the two ball socket elements 6a, 6b are complementary to the ball element 5 and enclose the ball element fifth
