The invention discloses a method for eliminating abnormal sound of an electrically-driven rear axle, the electrically-driven rear axle and a vehicle, and relates to the technical field of vehicles, and the method comprises the steps of preparing a mixed lubricant, smearing the mixed lubricant and assembling a motor and the rear axle. In the step of preparing the mixed lubricant, the mixed lubricant comprises a lubricant and an additive, and the additive is one of graphite powder or metal powder; in the step of smearing the mixed lubricant, the mixed lubricant is uniformly smeared on the surface of an internal spline of a motor and the surface of an external spline of a rear axle; in the step of assembling the motor and the rear axle, the motor and the rear axle are in transmission connection through the internal spline and the external spline. The mixed lubricant formed by mixing the lubricant and the additive is evenly smeared on the surface of the internal spline of the motor and the surface of the external spline of the rear axle, the gap between the internal spline and the external spline in transmission connection can be filled, and therefore abnormal sound generated by the electrically-driven rear axle can be eliminated, the requirement for size precision of the internal spline and the external spline is lowered, and the service life of the motor is prolonged. And the assembling efficiency of the electrically-driven rear axle is improved.
本申请公开了一种消除电驱动后桥异响方法、电驱动后桥及车辆,涉及车辆技术领域,包括步骤制备混合润滑剂、步骤涂抹混合润滑剂和步骤装配电机和后桥;在制备混合润滑剂的步骤中,混合润滑剂包括润滑剂和添加剂,添加剂为石墨粉或金属粉中的一种;在涂抹混合润滑剂的步骤中,将混合润滑剂均匀涂抹于电机的内花键表面和后桥的外花键表面;在装配电机和后桥的步骤中,将电机和后桥通过内花键和外花键传动连接。本申请通过由润滑剂和添加剂混合而成的混合润滑剂均匀涂抹于电机的内花键表面和后桥的外花键表面,可填补内花键和外花键传动连接之间的间隙,从而可消除电驱动后桥产生的异响,降低对内外花键的尺寸精度要求,提高电驱动后桥的装配效率。
