The invention discloses a light truck rear axle hub bearing unit. Belongs to the technical field of light truck hub bearing units. The hub bearing unit is mainly provided for a 600P rear axle of a Qingbell KV 100 light truck, and the quality guarantee mileage of the hub bearing unit reaches 500,000 kilometers. The wheel hub is mainly characterized by comprising a wheel hub, an outer bearing and an inner bearing, a middle spacer sleeve is arranged between the outer bearing and the inner bearing and is made of 45 # steel; the axial clearance of the light truck rear axle hub bearing unit ranges from-0.05 mm to 0.10 mm, and the spare tightening torque is 800 Nm. In the using process, the middle spacer sleeve made of the 45 # steel can compensate a gap caused by bearing abrasion, the stability of the bearing clearance is kept, and therefore the reliability and the long service life of the hub bearing and a unit are guaranteed. The 600P rear axle has the characteristics of improved bearing performance, no maintenance, long service life and improved transmission efficiency, and is mainly used for a 600P rear axle of a Qingbell KV100 light truck.
本发明的名称一种轻卡后桥轮毂轴承单元。属于轻卡轮毂轴承单元技术领域。它主要是为庆铃KV100轻卡600P后桥提供一种质保里程达50万公里的轮毂轴承单元。它的主要特征是:包括轮毂、外轴承和内轴承;所述外轴承与内轴承之间设有中间隔套,中间隔套的材料为45#钢;轻卡后桥轮毂轴承单元的轴向游隙为‑0.05~0.10mm,备紧力矩是800Nm;在使用过程中45#钢材质的中间隔套可以补偿轴承磨损带来的间隙,保持轴承游隙的稳定,从而确保了轮毂轴承及单元的可靠性和长寿命。本发明提高承载性能、免维护、使用寿命长和提高传动效率的特点,主要用于庆铃KV100轻卡600P后桥。
