ABSTRACT:
A vehicle headlamp has a reflector coupled to a lamp housing via a pivotal connection and two aiming mechanisms for tilting the reflector relative to the lamp housing about horizontal and vertical axes intersecting at the pivotal connection. One such aiming mechanism comprises an aiming screw rotatably mounted to the lamp housing, a socket member affixed to the back of the reflector, and a ball with a tapped hole extending therethrough to fit over the aiming screw. The socket member has a hollow extending therethrough for receiving the aiming screw with clearance. Part of the hollow in the socket member is formed into a socket for rotatably receiving the ball on the aiming screw. A lockpin on the ball is engaged in a slot in the socket member thereby locking the ball against rotation relative to the socket member about the axis of the hole therein. The bidirectional rotation of the aiming screw is therefore translated into the linear reciprocation of the ball together with the socket member, which member is additionally free to undergo angular displacement relative to the ball for smoother tilting of the reflector.
