Description

Hub unit structure for improving safety Technical Field The utility model relates to the technical field of hub bearing units, in particular to a hub unit structure for improving safety. Background The hub bearing unit is one of the key components of the vehicle, its main function being to carry the weight and to provide accurate guidance for the rotation of the hub, which requires it to be able to carry not only axial loads but also radial loads. However, the existing vehicle is fixedly connected with the hub unit through the chassis and the suspension through flanges, and the adjustment of the center distances of hubs at two ends of the vehicle body cannot be realized. The weight ratio of the left and right of the vehicle often has a difference, and when the vehicle is over-bent, the vehicle can deviate outwards or inwards, so that a driver is required to adjust the direction according to the situation. Disclosure of Invention The utility model mainly solves the defects existing in the prior art, and provides a hub unit structure for improving safety, which has the characteristics of compact structure, adjustable left-right spacing of hubs, high structural strength and good running stability. Through fine setting the size of the left-right spacing of the hub units, the problem of vehicle over-bending safety is solved. The safety and reliability of the vehicle over-bending running are improved, and scraping caused by overlarge deviation during over-bending is avoided. The technical problems of the utility model are mainly solved by the following technical proposal: the utility model provides a promote hub unit structure of security, includes the hub unit, hub unit upper end be equipped with the guide rail pole, guide rail pole and hub unit between be equipped with hub unit looks fixed and with the guide block of guide rail pole looks slidingtype grafting, hub unit lower extreme be equipped with sideslip adjustment cylinder, sideslip adjustment cylinder and hub unit between be equipped with the slide. The guide rail rod is internally provided with the guide groove which is in limit insertion connection with the guide block, and the guide block and the outer ring are in an integrated welding or casting structure, so that the structural integrity and stability are ensured. The guide block is fixed with the hub unit and is in sliding connection with the guide rail rod, and the design realizes that accurate guide is kept in the sliding process, and friction and abrasion are reduced. Preferably, the hub unit comprises a flange plate, an outer ring sleeved with the flange plate in a sliding mode is arranged on the flange plate, a pair of inner rings distributed in a mirror symmetry mode are arranged between the outer ring and the flange plate, a retainer is arranged between the inner ring and the outer ring, and a plurality of steel balls distributed in a ring shape and clamped with the retainer in a rolling mode are arranged in the retainer. Preferably, a dustproof framework sealing ring is arranged between the inner side end of the outer ring and the inner ring, and a magnetic framework sealing ring is arranged between the outer side end of the outer ring and the inner ring. Preferably, an arc support block which is fixedly connected with the outer ring and the sliding plate by a screw is arranged between the sliding plate and the outer ring. The arc supporting blocks are arranged between the sliding plate and the outer ring and are fixedly connected through the screws, so that the tightness of the structure is enhanced, and external impurities are prevented from entering. Preferably, the guide block and the outer ring are in an integrated welding structure or an integrated casting structure.
