Problems solved by technology

However, the rolling performance of existing nuts is average. After the wheel bearing is used for a long time, the rolling performance is weakened due to the large internal wear of the bearing, which affects the normal driving of the car, and the life of the wheel bearing is short.

Abstract

The invention discloses an automobile hub bearing with good rolling performance. The automobile hub bearing comprises a shaft, a hub bearing center ring, a hub bearing outer ring, a hub flange, a first inner bearing, a second inner bearing, a first outer bearing and a second outer bearing, and one end of the shaft is provided with the hub flange. The hub bearing is internally provided with a double-layer bearing structure, the first inner bearing and the second inner bearing form a first layer rolling structure, the first outer bearing and the second outer bearing form a second layer rolling structure, so that the rolling performance can be improved, the pressure and friction force during long-time use and high-speed rotation of the bearing are reduced, the service life of the bearing is prolonged, the wheel hub bearing still keeps a good rolling performance after being used for a long time, the safety is improved, the other wheel hub bearing can still support normal rotation of the wheel even if one layer of rolling structure is damaged in the driving process, and accidents caused by the fact that the wheel is not rotated are avoided.

Description

【Technical field】 [0001] The invention relates to the technical field of bearings, in particular to the technical field of automobile hub bearings with good rolling performance. 【Background technique】 [0002] Wheel hub bearing is one of the key components of the automobile. Its main function is to carry weight and provide precise guidance for the rotation of the hub. This requires it to bear not only the axial load but also the radial load. At present, the existing hub The bearing structure generally includes a coaxial bearing outer ring, bearing inner ring and flange inner ring, etc., steel balls are set between the flange inner ring and the bearing outer ring, steel balls are set between the bearing inner ring and the bearing outer ring, and the bearing inner ring The axial direction with the inner ring of the flange is usually fixed by means of nut locking. However, the rolling performance of existing nuts is average. After the wheel hub bearing is used for a long time,...
