Abstract
Th utility model discloses a wheel bolt which comprises a screw rod and a nut. The screw rod of the wheel bolt is composed of two sections and comprises an inner screw rod and an outer screw rod, wherein a shaft shoulder separating the two sections is arranged between the inner screw rod and the outer screw rod. The inner screw rod comprises a thread part with outer threads and a connection part with a smooth surface. The outer screw rod comprises a thread part with outer screws. An inner nut is connected inside the inner screw rod. An arc surface for tightening a hub is arranged between the shaft shoulder and the outer screw rod in a transitional mode. A threaded sleeve is connected on the outer screw rod in a threaded mode and comprises a sleeve head and a sleeve rod, wherein a conical surface for tightening a hub is arranged between the sleeve head and the sleeve rod in the transitional mode, the sleeve rod is provided with outer threads, and an outer nut is connected on the sleeve rod in a threaded mode. The wheel bolt strengthens tightness of hubs, two hubs are separately tightened, relative friction is not generated, abrasion of the hubs is avoided, and service life of the hubs is prolonged.
Description
Technical field
The utility model relates to a kind of fastening piece, relates in particular to the wheel bolt of a kind of wheel place's connection wheel hub.
Background technique
Connection between two wheel hubs of existing truck one side all adopts the wheel bolt of wheel place's connection wheel hub to connect.As shown in Figure 1, existing wheel bolt comprises screw rod and nut, the screw rod of wheel bolt forms by two sections, comprise inner screw 1 and external screw rod 2, be provided with the shaft shoulder 5 of two sections of isolation between inner screw and external screw rod, inner screw and external screw rod comprise respectively with externally threaded screw section and ganoid joint, are connected with the inner nut 3 that has been threaded on inner screw, are socketed with nut collar 6 on external screw rod and are fixedly connected with outer nut 4.The inner screw of this wheel bolt is fixedly connected with the axletree steel ring by inner nut, two wheel hubs of joint socket of external screw rod, be fixedly connected with by outer nut after putting nut collar, because two wheel hubs directly are connected, when outer nut is loosening, produce relative friction slip between two wheel hubs, cause wearing and tearing mutually between wheel hub, reduce the working life of wheel hub.
The model utility content
The purpose of this utility model is to provide the wheel bolt of a kind of wheel place's connection wheel hub, having solved two wheel hubs of existing wheel bolt external screw rod socket directly fixes by outer nut, when outer nut is loosening, produce relative friction slip between two wheel hubs, cause wearing and tearing mutually between wheel hub, reduce the problem in the working life of wheel hub.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
a kind of wheel bolt, comprise screw rod and nut, the screw rod of wheel bolt forms by two sections, comprise inner screw and external screw rod, be provided with the shaft shoulder of two sections of isolation between inner screw and external screw rod, inner screw comprises with externally threaded screw section and ganoid joint, external screw rod comprises with externally threaded screw section, be connected with inner nut in inner screw, between the described shaft shoulder and external screw rod, transition is provided with the arc surface of being convenient to fastening wheel hub, swivel nut has been threaded on external screw rod, swivel nut comprises pullover and loop bar, between pullover and loop bar is interior, transition is provided with the conical surface of being convenient to fastening wheel hub, be provided with outside thread on loop bar, outer nut has been threaded on loop bar.Arc surface and swivel nut pullover of this wheel bolt by being convenient to fastening wheel hub, be convenient to conical surface and fastening two wheel hubs of outer nut difference of fastening wheel hub, strengthened fastening to wheel hub, and two wheel hubs are separately fastening, can not produce relative friction, prevent the wheel hub wearing and tearing, extended the working life of wheel hub.
As preferably, the cover boom end of described swivel nut is provided with jack, is plugged with jump ring in jack.Prevent that outer nut from coming off and cause wheel hub to fly out by jump ring is set.
The beneficial effects of the utility model are: adopt this wheel bolt to strengthen fastening to wheel hub, and two wheel hubs are separately fastening, can not produce relative friction, prevented the wheel hub wearing and tearing, extended the working life of wheel hub.
