Abstract

An axle support for a motor vehicle includes at least one first support and at least one second support fitted onto the first support. A cavity between the first and second supports that is defined by the surfaces of the supports and circumferential sealing rings is filled with adhesive to adhere the supports to one another. One of the supports is preferably made of metal, preferably cast aluminum, and the other support is preferably made of fiber-reinforced plastic.

First claim

What is claimed is:

1. An axle support for a motor vehicle, comprising:
at least one first support;
at least one second support;
an adhesive; and
two circumferential sealing rings,
wherein
each of the at least one second support is fitted onto a corresponding one of the at least one first support,
one of the at least one first support and the at least one second support is made of metal and the other of the at least one first support and the at least one second support is made of fiber-reinforced plastic,
the adhesive fills a cavity delimited by an outer surface of the at least one first support, an inner surface of the at least one second support and the two circumferential sealing rings.

2. The axle support according to claim 1 , wherein the metal is cast aluminum.

3. The axle support according to claim 1 , wherein the two circumferential sealing rings are configured to keep the at least one first support and the at least one second support spaced apart.

4. The axle support according to claim 3 , wherein a channel for injection of the adhesive into the cavity is formed in at least one of the first and second supports.

5. The axle support according to claim 4 , wherein the channel extends beyond the cavity in a longitudinal direction of the support containing the channel.

6. The axle support according to claim 5 , wherein
the at least one first support is two first supports disposed as longitudinal supports of the axle support,
the at least one second support is two second supports disposed as transverse supports of the axle support, and
the two longitudinal supports are made of metal and the two transverse supports are made of fiber-reinforced plastic.

7. A method for producing an axle support for a motor vehicle, comprising the acts of:
providing a first support and a second support, wherein one of the first and second supports is made of metal and the other one of the first and second supports is made of fiber-reinforced plastic;
fitting a first circumferential sealing ring onto one end of the first support, and fitting a second circumferential sealing ring onto one end of the second support;
inserting the first support into the second support such that a cavity is formed between an outer surface of the first support, an inner surface of the second support and the two circumferential sealing rings; and
filling the cavity with an adhesive.

8. The method according to claim 7 , wherein the metal is cast aluminum.

9. The method according to claim 7 , further comprising the acts of:
inserting a place-holder element configured to conduct the adhesive to the cavity into an aligned recess formed in the first and second supports prior to the act of filling the cavity with the adhesive; and
removing the place-holder element from the aligned recess after the act of filling the cavity with the adhesive.
