Problems solved by technology

[0002] At present, the EPSc steering column has received many noise complaints and claims from customers. It has been confirmed through test and analysis that most of the mechanical noise comes from the matching gap between the wedge-shaped support plate of the sensing unit and the servo housing, and the support plate of the sensing unit and the servo housing are both Metal parts, the two will make a lot of noise during the collision process, which will have a great impact on the service life and comfort of the entire EPSc

Abstract

The invention relates to the technical field of automobile part manufacturing, and in particular to a structure for improving noise of EPSc driving units and an inclination angle calculation method. Through matching a 15-degree wedge-shaped mechanism with a rubber spring with a certain rigidity, mechanical noise complaints generated in fit clearance between a sensing unit and servo shell can be solved, the product quality can be enhanced, the after-sale claims for compensation can be decreased, and favorable economy can be provided; and meanwhile, the wedge-shaped mechanism is made of a non-metal part, so that the manufacturing is convenient and the part cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of auto parts production and manufacturing, in particular to a structure for improving the noise of an EPSc drive unit and a calculation method for an inclination angle. Background technique [0002] At present, the EPSc steering column has received many noise complaints and claims from customers. It has been confirmed through test and analysis that most of the mechanical noise comes from the matching gap between the wedge-shaped support plate of the sensing unit and the servo housing, and the support plate of the sensing unit and the servo housing are both Metal parts, the two will make a lot of noise during the collision, which will have a great impact on the service life and comfort of the entire EPSc. [0003] Therefore, it is very necessary to design a structure to improve the noise of the EPSc drive unit and a calculation method for the inclination angle. Contents of the invention [0004] The inven...
