Holding element for connecting a rod to the body of a vehicle using an elastic bearing
The invention relates to a holding element for connecting a rod ( 1 ) to the body or the chassis of a vehicle using an elastic bearing ( 2 ). Said bearing consists of at least one outer sleeve and one inner sleeve ( 3, 4 ) provided with an elastic material ( 5 ), especially a rubber material, in the annular region ( 6 ) between the two sleeves. The outer sleeve ( 3 ) is fixed to the body or the chassis, and the inner sleeve ( 4 ) is connected to the rod ( 1 ) by means of a pin ( 7 ). Said pin extends through the inner sleeve ( 4 ) and carries a securing disk ( 9 ) on its free end, which secures the elastic bearing ( 2 ) against damaging offset in the event of defective adhesion of its individual parts in the axial direction. Furthermore, the securing disk extends in the radial direction at least to the outer sleeve ( 3 ) and at least part of its outer circumference is embodied in such a way that it is oriented in an essentially concave manner away from the elastic bearing ( 2 ). Said adaptation of the securing disk ( 9 ) significantly increases the section modulus of the same, enabling a relatively thin securing disk ( 9 ) to be used.
1 . Holding element for connecting a rod ( 1 ) to the body or the chassis of a vehicle by means of an elastic bearing ( 2 ) consisting at least of one outer and one inner sleeve ( 3 , 4 ) provided with an elastic material ( 5 ), especially a rubber material, in the annular region ( 6 ) remaining there-between, wherein the outer sleeve ( 3 ) is fixed to the body or the chassis and the inner sleeve ( 4 ) is connected with the rod ( 1 ) by means of a pin ( 7 ) which is extending through the inner sleeve ( 4 ) and is carrying a securing disk ( 9 ) on its free end which secures the elastic bearing ( 2 ) against damaging offset in the event of defective adhesion of its individual parts in the axial direction by extending in the radial direction at least to the outer sleeve ( 3 ), characterized in that the securing disk ( 9 ) at least over a part of its outer circumference ( 10 ) is shaped basically concave away from the elastic bearing ( 2 ).
2 . Holding element according to claim 1 , characterized in that the securing disk ( 9 ) at least over a part of its outer circumference ( 10 ) is bent away from the elastic bearing ( 2 ) in such a way that thereby a nut screwed onto the free end ( 8 ) of the pin ( 7 ) or the head of a machine screw ( 11 ) is held securely against rotation.
3 . Holding element according to claim 2 , characterized in that the securing disk ( 9 ) is bent several times, at least three times, over a part of its outer circumference ( 10 ) away from the elastic bearing ( 2 ).
