Definitions
- the invention relates to a suspension strut bearing having a cap and a guide ring rotatably mounted about a rotation axis relative to the cap, wherein a thrust bearing is disposed between the cap and the guide ring, the cap comprising a soft component and a hard component, and further the soft component has at least two circumferential sealing lips, which abut the sealing ring of the axial bearing for sealing the axial bearing.
- Strut bearings are part of the suspension for independent suspension.
- the suspension supports a desired driving safety and driving comfort, as well as easy and precise steering of the wheels.
- the suspension should keep road noise from the structure and be as light as possible.
- the suspension strut bearing guides the shock absorber spring and forms a support surface for the shock absorber end stop.
- the strut bearing absorbs the transmitted via the shock absorber spring and the shock absorber radial and axial forces and ensures that the shock absorber spring during steering and compression twisted friction and tension-free and thus operates without restoring moment.
- Strut bearings are often part of the so-called McPherson struts.
- the strut consists essentially of spring, shock absorbers and steering knuckle.
- the strut bearing is provided with a cap which is fixed to the chassis-side strut tower, and with a guide ring on which the shock absorber spring is supported and guided by this.
- the guide ring is rotatably mounted relative to the cap.
- the bearing allows steering of the spring relative to the body during steering, as the entire strut rotates during steering movements. From DE 10 2006 057 559 A1 a suspension strut bearing is known which has a cap consisting of a soft component and a hard component and a guide ring rotatable relative to the cap.
- the soft component is formed as a sealing element which extends from an inner periphery to an outer periphery of the cap.
- the soft component has two sealing lips. The sealing lips are rubbing against the guide ring. Since the soft component is arranged on an end face of the hard component directed toward a dome bearing, ie between the hard component and the dome bearing, no matching of the profile of the hard component to the profile of the dome bearing can take place, whereby an optimal contact of the strut bearing with the dome bearing would be feasible. Rather, the profile of the Domlagers penetrates into the soft component and can even damage it under unfavorable circumstances.
- the soft component is formed on an end face of the hard component facing the guide ring, and an end face of the hard component directed opposite thereto has a profile.
- the soft component extends between the hard component and the guide ring, whereby the end face of the cap coming into contact with the dome bearing is formed exclusively by the hard component.
- this also allows a simple and cost-effective production of strut bearing, in particular the cap.
- the hard component is produced by injection molding and, in a subsequent second production step, the soft component is produced by injection molding on the end face of the hard component facing the guide ring.
- the profile of the dome bearing to the plant coming face can be designed almost arbitrarily.
- the profile of the end face of the hard component is designed to be complementary to a profile of a adjacent thereto Domlagers. That means a Increasing the profile on the end face of the Domlagers engages in a recess in the profile at the end face of the hard component.
- the profile preferably has at least one recess for a screw element on the end face of the hard component.
- the screw elements, in particular the screw heads are received by the at least one recess in the hard component.
- a first circumferential sealing lip abuts against an outer peripheral surface of the guide ring, and a second circumferential sealing lip abuts against an inner peripheral surface of the guide ring.
- the soft component encloses the thrust bearing and sealing seals on the two sealing lips on the guide ring.
- the second circumferential sealing lip is hook-shaped and arranged in a circumferential groove on the guide ring.
- the cap can be hacked on the guide ring and secured axially by this snap connection.
- a third circumferential sealing lip abuts against the outer peripheral surface of the guide ring.
- the third circumferential sealing lip is used in particular for sealing against rough contamination to the outside, so that the sealing effect is increased overall.
- the invention includes the technical teaching that the first circumferential sealing lip is connected via at least two webs to the second circumferential sealing lip. Due to the at least two webs between the first circumferential sealing lip and the second circumferential sealing lip, the soft component can be produced in one production step. Furthermore, the at least two webs provide improved hold between soft component and hard component.
- the soft component has at least two axial fuses, which completely fill at least two recesses provided in the hard component.
- the hard component has at least two recesses which are filled with the soft component during the injection molding of the soft component.
- the at least two recesses have a shape deviating from the flow channels, in particular a larger diameter to allow axial securing of the soft component in the hard component.
- the soft component is made of a Elastolanwerkstoff and the hard component made of a Poyamidwerkstoff.
- the Poyamidwerkstoff is due to its rigidity particularly well suited to absorb forces and the Elastolanwerkstoff is particularly well suited for sealing due to its elasticity.
- Figure 1 is a perspective sectional view of an inventive
- Figure 2 is a perspective sectional view of the invention
- FIGS. 1 and 2 shows a perspective sectional view of the cap according to the invention from FIGS. 1 and 2.
- FIGS. 1 and 2 show a suspension strut bearing according to the invention with a cap 1, as well as a guide ring 2 made of a glass-fiber reinforced plastic, which is rotatably mounted relative to the cap 1 about an axis of rotation D.
- the cap 1 is arranged on a - not shown here - Domlager a chassis of a motor vehicle and comes with an end face to the plant.
- the guide ring 2 takes an axial end of a - not shown here - shock absorber spring. Spring forces of the shock absorber spring are passed over the guide ring 2 in the cap 1 and from there into the cathedral camp.
- the guide ring 2 is mounted axially on the cap 1 via a thrust bearing 3 in the direction of the axis of rotation D.
- the thrust bearing 3 is used for the transmission of forces acting along the axis of rotation D of the guide ring 2 on the cap 1.
- the thrust bearing 3 has a plurality between two bearing rings 13a, 13b mounted rolling elements 14.
- the cap 1 is formed as an annular two-component component and comprises a soft component 4 made of a Elastolanwerkstoff and a hard component 5 of a Poyamidwerkstoff.
- the cap 1 is preferably produced in a two-component injection molding process, in which first the hard component 5 is pre-sprayed and the soft components 4 are injected by injection to form a material bond.
- the soft component 4 is formed on an end face of the hard component 5 directed towards the guide ring 2.
- the end face of the hard component 5 coming to the abutment has a profile 7, which is characterized by elevations and depressions.
- the profile 7 of the end face of the hard component 5 is designed to be complementary to a profile of the adjacent thereto Domlagers.
- the profile 7 on the end face of the hard component 5 has two recesses 10a, 10b for each screw element.
- the soft component 4 forms the seal of the suspension strut bearing and comprises three circumferential sealing lips 6a, 6b, 6c.
- a first circumferential sealing lip 6a abuts against an outer peripheral surface of the guide ring 2
- a second circumferential sealing lip 6b abuts an inner circumferential surface of the guide ring 2.
- the second circumferential sealing lip 6b is hook-shaped and comes in a circumferential groove 1 1 on the guide ring 2 to the plant.
- the cap 1 is connected by means of a snap connection with the guide ring 2.
- the third circumferential sealing lip 6 c is formed directly adjacent to the first circumferential sealing lip 6 a and also comes to rest on the outer peripheral surface of the guide ring 2.
- the soft component 4 has five axial securing devices 9a-9e, which completely fill five recesses 12a-12e provided in the hard component 5 for this purpose. As a result, an axial release of the soft component 4 is prevented.
