Integrated window regulator assembly

摘要

A rattle mitigation assembly for a window regulator installed in a vehicle door includes drive unit housing having a port with a mouth of a cylindrical cavity adapted to receive a connector of a sheathed cable; a profiled end face extending around the mouth; and a slot extending radially outward from the cylindrical cavity, along the cylindrical cavity and through the end face. The end face forms a radially sloped ramp profile configured to exert a radial bias on a compression spring surrounding the connector and abutting the end face. An optimal slope angle of the ramp for urging the spring in the radial direction lies in the range of 45° through 80° with respect to a plane extending radially relative to the cylindrical cavity. An optional wedge profile with an increasing elevation along a direction away from the radially sloped ramp profile may be arranged opposite the ramp profile to exert an axial bias on the compression spring.

1. A rattle mitigation assembly for window regulator installed in a vehicle door, comprising
a spring cap having a connector having a cylindrical portion and a radial collar, and a compression spring surrounding the cylindrical portion and abutting the radial collar; and a drive unit housing having a port for the spring cap, the port including
a mouth of a cylindrical cavity adapted to receive a section of the cylindrical portion; anda profiled end face extending around the mouth, the end face forming a radially sloped ramp along only a portion of the mouth and exerting a radial bias on a portion of the compression spring that abuts the radially sloped ramp.
