On the micro car wheel bearing project

Number of car wheel angular contact ball bearing used is a single bearing paired installation, as shown in figure 1. 25. After loaded on the wheel must be adjusted to eliminate the axial clearance. Truck wheel with taper roller bearings are the same. To prevent pollutants from entering the bearing, and sealing ring. This type of bearings need to grease lubrication, and due to the failure, under the condition of the grease will need to be replaced regularly new grease. If not careful protection, bearing inevitably affected by pollution and bearing life. In order to overcome these problems, most of the bearing unit have been preset adjustment before the date of delivery, greasing and sealed for life, as shown in figure 1. 62 a. These units need to be pressed into the wheel hub. To simplify the automobile assembly process, at the same time, also in order to reduce the volume, as shown in figure 1. 62 b, add a flange on the outer ring, so that the bearing can be mounted on the wheel with screw. Later on each ring has been applied with flange bearing unit, as shown in figure 1. 62 c, it would be very refers to a single fixed and the wheels on the car body structure. Type of overloading vehicles such as vans, can use tapered roller bearings, Figure 1. 63). Instead of ball bearing. Bearing unit can also add some functionality, as shown in figure 1. 64 tapered roller bearing units. This tight adjusted in advance of the whole bearing unit installed a speed sensor for anti-lock brake system ( ABS) Provide signals can also be installed on the rolling bearing measuring load sensor.
