  • Drive-in bushing, motor vehicle structure and method and tool for producing the motor vehicle structure
    Patent number: 9360041
    Abstract: A drive-in bushing (14) is provided for the releasable connection of a fiber-reinforced plastic first component of a motor vehicle structure to a fiber-reinforced plastic or metal second component of the motor vehicle structure. The drive-in bushing (14) has a sleeve-like basic body (15) manufactured from a metal and having an external wall (16) formed without a thread, and an internal wall (17) formed with an internal thread (18). The drive-in bushing (14) can be driven into a recess in the fiber-reinforced plastic of the first component (11). A screw penetrates a recess in the second component and can be screwed into the internal thread (18).
