Look at how the three generations of car wheel hub bearing installation? 2020 - 03 - 27 car wheel hub bearing is important part of vehicle system, the effect is a bearing body and provide accurate guide to the rotation of the wheel hub. At present, the mature of wheel hub bearing has developed to the third generation, one of the highest technical requirements for maintenance personnel is the first generation. This is due to the bearing inner ring and outer ring are connected by interference fit and related parts, when installation will need to use special tools or press the pressure into the corresponding parts. The first generation of car wheel hub bearing a generation of car wheel hub bearing's outer ring and inner ring back-to-back combination of double row angular contact ball bearings and double row circular cone roller bearings. In order to ensure the pre-tightening load after installation within the prescribed scope, initial bearing clearance, preset on the assembly line without using the pre-tightening load adjustment baffle. In addition, the wheel hub bearings with seals, eliminating the steps of artificial external installation sealing ring. Installation using the adaptation of the generation of wheel hub bearing pressure with the inner ring, remove the positioning circlip, slow pressure out of the outer ring, check the hole. New bearing in the bearing hole, using adaptation pressure with pressure on the outer face of the bearing pressure slowly sit down hole, flange installation, slowly pressed bearing to limit position. Note: in strict accordance with the vehicle maintenance manual half-and-half axle bolt fastening, being connected to ensure clean and sufficient lubrication bearing, don't forget spring. Otherwise it will have serious accident maintenance. The second generation compared with the first generation of car wheel hub bearing outer ring flange of the second generation of wheel hub bearing is characterized by assembling parts number is less, light in weight and easy installation. The second generation of wheel hub bearing outer ring with flange, through the self-contained bolt connection directly to the suspension, Inner ring rotation type) , or mounted to the brake disc and rims ( Outer ring rotation type) 。 The second generation of car wheel hub bearing bearing sealing cover installation using adapter calipers removal, demolition of holding down bolt and gaskets, remove the brake. Pressure after installed, pull out bearing flange, raceway clean flanges and pull it out, clean axle before you install the new bearing. Note: in strict accordance with the vehicle maintenance manuals for bearing bolts, ensure clean install shaft during installation. Don't forget to adjust gasket ( If there is one) , otherwise it will produce other joint failure. The third generation of car wheel hub bearing by the third generation wheel hub bearing is connected to the suspension of the flange on the outer ring and connected to the brake disc and rims flange of the inner ring phase composition. Unlike the second generation, the third generation wheel hub bearing integrates ABS sensor. Three generations of car wheel hub bearing installation using adapter calipers removal bearing sealing cover, clean and half shaft screw, remove loosening device. Pressure after installed, the ball cage outside half shaft, demolition of brake parts and bearings, thoroughly clean the seat hole after installation, install the new bearing. Note: in strict accordance with the vehicle maintenance manuals for bearing and axle shaft bolt fastening, when installation to ensure that the bearing hole cleaning. Don't touch the magnetic code ring. Hk united bearing focus bearing industry informationization service nearly 20 years, with many excellent bearing enterprise grows together, also witnessed China's bearing production technology from low to high development process. We will adhere to continue, the steadfast work, don't, don't give up, for the benign development of Chinese bearing industry do render some. Hk united bearing network bearing engineers, 2019. 09. 27
