Quick adjusting nut, especially for attaching a vehicle wheel to the mounting shaft of a balancing machine

摘要

A quick adjusting nut (1) made especially for attaching a vehicle wheel to the mounting shaft of a balancing machine, with a housing part (2) and with at least two radially movable thread segments (3) arranged in the housing part (2) and with an actuator (4) for radial movement of the thread segments (3), each thread segment (3) having an inside thread section (3a) and the thread segments (3) being radially movable along guide surfaces (7) of the housing part (2) from an engagement position outward into a disengagement position. The guide surfaces (7) for the thread segments (3) slant upward in the radial outward direction and interact with complementary slanted guide surfaces of the thread segments (3) during movement in the radial direction.

1. Quick adjusting nut for attaching a vehicle wheel to the mounting shaft of a balancing machine, comprising:
a housing part, at least two thread segments arranged to move radially in the housing part along guide surfaces of the housing part radially outward from an engagement position into a disengagement position, each thread segment having an inside thread section, and an actuating means for radially moving the thread segments, wherein the guide surfaces are slanted so as to rise in a radially outward direction and interact with complementary slanted face surfaces of the thread segments during radial movement of the thread segments, and wherein the guide surfaces have a pitch angle that is between 1° to 5° larger than half of a flank angle of a thread of the inside thread sections.
