Abstract: Disclosed is a wheel outer rim fillet dressing device, including a rough wheel positioning system, a precision wheel positioning system, a wheel rotating system and a cutter dressing system. After a wheel is roughly positioned, an electric cylinder drives a moving plate to descend to an appropriate position, an adjusting cylinder drives a right sliding table to move right, a left sliding table moves synchronously with right sliding table under the action of a second gear rack, thus the distance between a precision positioning post on left sliding table and a precision positioning post on right sliding table is adjusted, and precision positioning posts contact vertical surface of cap seam allowance of wheel and hold the wheel tightly. The adjusting cylinder is restarted, and outer rim fillets can be dressed when the distance between two dressing cutters is adjusted to an appropriate position and under the cooperation of rotating wheel.

Abstract: A wheel and a rim with weight reduction sockets are provided. The rim includes an inner flange, a middle portion and an outer flange, the inner flange, middle portion and outer flange are all annular and are connected end to end to form a cylindrical rim, in which the middle portion of the rim includes weight reduction sockets; and the weight reduction sockets are of regular hexagons, and are arranged adjacently on the outer side of the middle portion of the rim in the shape of a honeycomb. The weight of the hub is reduced by designing the weight reduction sockets in a specific shape for the outer rim of the hub and selecting the size of the weight reduction sockets.

Abstract: A wheel bolt hole chamfer device is composed of a base, a support frame, a lower servo motor, a turntable, stop blocks, guide rails, strong springs, a driving friction wheel, driven shafts, driven friction wheels, chamfer cutters and the like. The device can be put into a production line as a fourth-procedure machining device, and bolt hole chamfers are no longer machined in three procedures, so that the three-procedure machining time is reduced; and after the fourth procedure for machining the bolt hole chamfers is supplemented, the machining time of a single wheel is shortened, and the efficiency is improved. The device integrates pitch diameter adjustment and rotating drive of the chamfer cutters, so that a drive system and a power system are greatly simplified, i.e., the manufacturing cost of the device is reduced, all bolt hole chamfers can be machined at the same time.

Abstract: An automobile hub with a hollow rim includes a wheel disc and the rim with at least one hollow cavity, in which the rim includes at least two mutually nested rings and an axial end cap at the same ends of the at least two rings, and the hollow cavity consists of the rings and the axial end cap. The outer side of one end of the wheel disc includes axial rim mounting grooves, and the rim is inserted into the rim mounting grooves and fixed to the wheel disc through the end without the axial end cap. By employing the automobile hub with the hollow rim, the hub assembling method, and the automobile having the hub, the weight of the hub can be further reduced, and the hub has sufficient strength.
