Raceway bearing for sliding central dashboard of self driving automobile

Abstract

The invention relates of a raceway bearing for a sliding central dashboard of a self driving automobile. The bearing comprises an outer ring, rolling bodies, a retainer and an inner ring, wherein theretainer is arranged between the outer ring and the inner ring; seal rings are arranged on two sides of the retainer; a plurality of uniformly distributed rolling bodies are arranged in the retainer;the inner ring is higher than the outer ring; knurling grooves is formed in the periphery of an equidistant end surface of the outer side wall of the outer ring; and wearproof plastic is arranged outside the knurling grooves and uniformly circumferentially wraps the periphery of the outer ring. According to the raceway bearing, the inner ring is designed to be higher than the outer ring, non-wear-resistant aluminium backings are replaced, the mounting precision is high, and the reliability is high; and the two knurling grooves are formed in the periphery of the equidistant end surface of the outer ring, and the wearproof plastic uniformly and circumferentially warp the knurling grooves, stable and flexible operation is facilitated, and the noise is low.

Description

technical field [0001] The invention relates to a raceway bearing of a sliding central control panel of an automatic driving vehicle, belonging to the field of bearings. Background technique [0002] At present, the raceway bearings used for sliding center console panels of self-driving cars are mainly standard bearings composed of outer rings, inner rings, rolling elements, cages, grease, and sealing rings. Two aluminum alloy bearings need to be installed on both ends of the bearing during use. The gasket is used to fix the relative position of the bearing in the middle of the raceway, but the aluminum gasket is a non-wear-resistant material, and it will wear out after a period of use, causing the bearing to deviate from the predetermined raceway and causing the center control panel to move unsmoothly; in addition, the standard bearing There is no package of any material in the circle, and it is directly in contact with the raceway for rolling friction, resulting in high no...
