The utility model content
The purpose of this utility model is that connection mode can produce radial runout between existing constant-velocity universal joint and wheel hub when working, generation is vibrated and the deficiency of noise in order to overcome, a kind of radial runout that prevents is provided, prevents to vibrate fixed end constant-velocity universal joint and wheel hub composite set with noise.Concrete technical scheme of the present utility model is: fixed end constant-velocity universal joint and wheel hub composite set, comprise constant-velocity universal joint, and wheel hub, described constant-velocity universal joint has the clutch can bar, and described clutch can bar is that clutch can and bar portion are formed by connecting; Described clutch can bar is provided with attachment face, guide section, thread segment from clutch can successively to bar portion, and described guide section diameter is greater than thread segment; Described fixed end constant-velocity universal joint and wheel hub composite set are provided with gear ring, and described gear ring is that annular arrangement is enclosed within outside the clutch can bar guide section, and contacts with attachment face, is provided with the location rotation-preventing mechanism between described gear ring and clutch can bar; Described gear ring is provided with the gear ring end face tooth along the axle center circle distribution; Described wheel hub is provided with pilot hole, described pilot hole and guide section free-running fit; Described wheel hub is provided with along the wheel hub end face tooth of axle center circle distribution and the engagement of gear ring end face tooth; Described clutch can bar passes the wheel hub pilot hole, and nut is captiveed joint with clutch can bar thread segment.Described fixed end constant-velocity universal joint and wheel hub composite set are provided with gear ring, are provided with the location rotation-preventing mechanism between gear ring and clutch can bar, and described wheel hub is provided with along the wheel hub end face tooth of axle center circle distribution and the engagement of gear ring end face tooth; Replace spline to be connected with the engagement of end face tooth between fixed end constant-velocity universal joint and wheel hub, because not relative motion between gear ring and wheel hub, so adopting, wheel hub end face tooth and gear ring end face tooth can realize self-centering dental clutch profile of tooth, play transfer torque, prevent radial runout, prevent to vibrate and the purpose of noise; Gear ring is set separately, is convenient to the gear ring manufacturing; Be provided with the location rotation-preventing mechanism between gear ring and clutch can bar, reach the purpose that transfer torque makes gear ring and clutch can bar relative positioning again.
As preferably: described gear ring end face tooth is a stepped tooth; Described wheel hub right side tooth is a stepped tooth.Gear ring and wheel hub end face tooth are stepped tooth, and the stepped tooth transfer torque is bigger.
As preferably: described wheel hub left side is provided with depression.Nut is adjacent to the depression end face, can shorten the length of fixed end constant-velocity universal joint and wheel hub composite set.
As preferably: the location rotation-preventing mechanism is a locating dowel pin between described gear ring and clutch can bar, at least two of described locating dowel pins.Locating dowel pin plays the effect of location and anti-rotation between gear ring and clutch can bar, transfer torque.
The beneficial effects of the utility model are:
Described fixed end constant-velocity universal joint and wheel hub composite set have gear ring, play the effect of location and anti-rotation between gear ring and clutch can bar, transfer torque between gear ring and clutch can bar with locating dowel pin.The engagement of described wheel hub end face tooth and gear ring end face tooth replaces spline to be connected, and employing can realize self-centering, the dental clutch stepped tooth that transfer torque is bigger, plays transfer torque, prevents radial runout, prevents to vibrate and the purpose of noise.
