Zugfeder für Klappe an einem Kraftfahrzeug

摘要

Tension spring (12) for a flap (11) of a motor vehicle is fixed with one spring end to a fixed hinge point on the vehicle body and at the other spring end to a hinge point on the flap. A guide cylinder and a damping element with a cylinder/piston arrangement are inserted inside the cylindrical spring body. Two guide elements (13, 14) are provided for the cylindrical body. One damping element (15) of one guide element and its corresponding counterpart (damping element (18)) on the other guide element first come into contact in the end phase of the flap opening process. Preferred Features: The thread of a threaded pin (22) has a pitch corresponding to the pitch of the tension spring.
