The functions of the existing hub bearings for the off-road vehicles and the pick-up trucks are single, and the off-road vehicles and the pick-up trucks need more complicated field adaptability, so that the tapered roller bearing hub unit with the auxiliary climbing function comes up at the right moment.

When the traditional conical bearing roller hub unit is designed and produced, because the shaft diameter of a mandrel and the inner diameter of an inner ring are in interference fit, large interference can ensure excellent assembling force and firmness, but the large interference can cause overlarge deformation of a bearing raceway and a sealing straight gear, irregular abrasion is generated between a rolling body and the raceway, and the sealing performance fails in advance, so that the early failure of the bearing is caused; the deformation that bearing raceway and sealed straight keep off can be guaranteed very little to little magnitude of interference, but can lead to the reduction of assembly force and fastness, and under working conditions such as climbing, high load, the bearing inner race produces relative rotation with dabber shaft diameter, also leads to the bearing early failure.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a wheel hub bearing of supplementary climbing in area and function of getting rid of poverty is provided, through addding the gear assembly, can promote the supplementary climbing function and the function of getting rid of poverty of vehicle. Under the working condition of large-angle climbing, the bearing inner ring and the mandrel can be ensured not to rotate relatively, and the defects of early failure, breakage, slipping and the like of the hub are prevented.

The utility model provides a technical scheme that technical problem adopted is: the utility model provides a wheel hub bearing of supplementary climbing in area and function of getting rid of poverty, includes outer lane, inner circle, dabber, holder, roller, sealing member and bolt the dabber tip is equipped with the gear assembly, the gear assembly includes gear and gasket, the outer terminal surface of gear is connected with the transmission shaft, and interior terminal surface is connected with the dabber.

Preferably, splines are arranged on the outer end face and the inner end face of the gear, a spline I matched with the spline on the inner end face of the gear is arranged on the mandrel, and a spline II matched with the spline on the outer end face of the gear is arranged on the transmission shaft.

As a further improvement, a gear ring and a sensor are also provided.

Preferably, the inner ring includes an inner ring a and an inner ring B.

Preferably, the seal comprises a sealing ring, an O-ring and a sealing ring assembly.

Preferably, the material of the retainer is nylon and glass fiber.

The utility model discloses can be applied to the automobile drive wheel of taking real-time four-wheel drive function, provide the torque transmission mode beyond the internal spline under abominable operating mode, reduce the trouble incidence of product (such as fracture, race ring), promote user experience and vehicle performance; the system can also be used for automobile non-driving wheels with a timely four-wheel drive function, and when the torque of the driving wheels is transmitted within a set value of the system, the non-driving wheels do not participate in the work, so that the fuel consumption can be reduced, and the emission of atmospheric pollutants can be reduced; after the torque transmission of the driving wheel exceeds the set value of the system, the gear assembly on the non-driving wheel is meshed with the transmission gear to provide extra torque, so that the climbing function, the escaping function and the like of the vehicle are improved.

The utility model has the advantages that the auxiliary climbing function and the escaping function of the vehicle can be improved by additionally arranging the gear assembly. Under the working condition of large-angle climbing, the bearing inner ring and the mandrel can be ensured not to rotate relatively, and the defects of early failure, breakage, slipping and the like of the hub are prevented. The bearing has strong market adaptability, can prolong the service life of the bearing, improve the ultimate working condition performance of the product, reduce the after-sale problem of the product and create more value for enterprises.
