Abstract
The utility model belongs to the technical field of passenger car parts, and particularly discloses a passenger car steering column with a carbon brush conductive structure, which comprises a mandrel, a sleeve and a carbon brush assembly additionally arranged between the mandrel and the sleeve. The carbon brush assembly comprises a conductive part fixed on the inner wall of the sleeve or a related part, a carbon brush which is installed on the conductive part and forms sliding electric contact with the outer surface of the core shaft, and an elastic part which applies pressure to enable the carbon brush and the core shaft to keep continuous close contact. According to the utility model, a direct, low-resistance and stable conductive path between the mandrel and the sleeve is realized through the carbon brush, the reliability and the stability of conduction are obviously improved, and the normal operation and the driving safety of an electrical system of a passenger car are ensured.
