Abstract
The utility model discloses a novel wheel hub bolt, which comprises a head and a rod body. The length of the rod body is matched with the depth of a bolt insulation hole in a wheel hub. The part of the rod body, matched with the bolt insulation hole, is provided with an external thread. The outside of the rod body, between the external thread and the head, is provided with at least one circle of straight knurling. The outer diameter of the straight knurling and the outer diameter of the external thread are larger than the diameter of the rod body. At least one circle of rod body, without any external thread, is reserved between the straight knurling and the external thread so as to form a groove. A sealing ring matched with the groove is sleeved onto the groove. The tail end of the rod body is extended to be provided with a section of rod body without any external thread, wherein the section of rod body functions as a limiting rod. According to the technical scheme of the utility model, the sealing ring is arranged between the straight knurling and the external thread, and the combination part of the bolt with a nut is provided with sealant. Therefore, the bolt is effectively prevented from being corroded and oxidized, and the service life of the wheel hub bolt is prolonged. Meanwhile, the tail end of the rod body is extended and provided with the limiting rod, and the nut can be quickly sleeved onto the limiting rod. In addition, the nut is ensured to be screwed onto the bolt coaxially, and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of bolt, is specially a kind ofly for the boss bolt on wheel hub, belongs to hardware technical field.
Background technique
Bolt, is one of modal mechanical parts, the cylindrical threaded fastening piece of adapted nut.Bolt: by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, need coordinate with nut, for being fastenedly connected two parts with through hole.This Connecting format claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, be to belong to removably connect therefore bolt connects.
Boss bolt is called again tire bolt, in order to parts such as fixing brake drum and wheel hub and wheel disc and wheel hubs, coordinates in use with nut (comprising inner nut, cover nut and outer nut etc.), on fittings supply, is therefore and nut supply in full sets.
Boss bolt generally has stud bolt and two kinds of patterns of bolt:
(1) stud bolt formula boss bolt: stud bolt formula boss bolt is a double-screw bolt, and there is locating flange centre, and two ends have screw thread, in use, its inner is fixed on wheel hub, and outer end is connected with wheel disc with outer nut; During for trailing wheel twin tyre, need to add with cover nut and first fix when wheel disc interior, then will also fix with outer nut wheel disc when wheel disc is enclosed within on nut outward.
(2) bolt type boss bolt: one end is head, general all making cut the circle of and used as location is installed, the following shaft of head has rolled straight knurling, on its length and wheel hub, the degree of depth in construction bolt hole adapts, when installing, this bolt packs in the tapped hole of wheel hub with patting to coordinate, so save internal thread; The threaded part of bolt the other end tool, for the fixing wheel disc of outer nut.In the time that twins fills, also need to add encapsulation nut.
Nut used on boss bolt, except inner nut is identical with general nut.Ball (cone) face is all made in one end of cover nut and outer nut, makes to coordinate with the conical bolt hole on wheel disc.The screw thread of boss bolt and nut, except minority be left and right wheels general, great majority separate, the screw thread of wheel hub one end is installed, and right to take turns used be right-handed thread (along tooth), and what revolver was used is left-handed thread (anti-tooth), its screw thread (stud bolt formula) that is connected one end with wheel hub left and right wheels is right-handed thread, can avoid like this vehicle to advance time, nut has loosening possibility, and safety is guaranteed.
Also there is following problem in this bolt type boss bolt:
1, because automobile running is on the road of varying environment, therefore, wheel hub unavoidably will relate to rainwater, acid mist, dust etc., can, by the corrosion of wheel hub screw thread, cause boss bolt to get rusty for a long time.
2, outside thread starts up to straight knurling from the tail end of shaft, and because the pitch of screw thread is larger, such structure nut easily tilts while screw-in, loses time.
Model utility content
The purpose of this utility model is for a kind of novel boss bolt is provided, to solve the problems referred to above of prior art.
The purpose of this utility model is achieved through the following technical solutions.
A novel boss bolt, comprises head, and the degree of depth in the construction bolt hole shaft that adapts on length and wheel hub, on shaft, is provided with outside thread with cooperation place, construction bolt hole; Shaft arranged outside between outside thread and head has at least one circle straight knurling; The external diameter of straight knurling and externally threaded external diameter are greater than the diameter of shaft; Between straight knurling and outside thread, at least leaving a circle does not have externally threaded shaft, forms groove; On groove, be arranged with the seal ring of coupling; The tail end of described shaft is also extended with one section, and there is no externally threaded shaft be position-limited lever.
When described straight knurling is multiple, its external diameter size is different, and from head toward caudal directions, external diameter reduces gradually.With facilitate bolt install time with pat coordinate pack in the tapped hole of wheel hub.And the magnitude of interference that the external diameter of ladder-type can make mounting hole coordinate with boss bolt annular knurl place reduces amplitude and reduces, and extends the working life of boss bolt.
Described outside thread outside is coated with sealant layer.Can not get rusty in the junction that can ensure like this bolts and nuts.
The end face edge place of described position-limited lever is set to chamfering.
The utlity model has following beneficial effect:
1, between straight knurling and screw thread, seal ring is set, and is being provided with sealer with the junction of nut, can effectively prevent that bolt is corroded, is oxidized, increase the working life of boss bolt.
2, extend one section of position-limited lever at the tail end of shaft, can be rapidly by spiro cap, and ensure coaxial screw-in, can not tilt to cause the problem of again twisting; Improve working efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side-looking structural representation of the present utility model;
In figure: 1, head 2, shaft 3, outside thread 4, straight knurling 5, groove 6, position-limited lever.
Embodiment
Further set forth structural feature of the present utility model below in conjunction with specific embodiment.
A kind of novel boss bolt as depicted in figs. 1 and 2, comprises head 1, and the degree of depth in the construction bolt hole shaft 2 that adapts on length and wheel hub, on shaft 2, is provided with outside thread 3 with cooperation place, construction bolt hole; Shaft arranged outside between outside thread 3 and head 1 has at least one circle straight knurling 4; The external diameter of the external diameter of straight knurling 4 and outside thread 3 is greater than the diameter of shaft 2; Between straight knurling 4 and outside thread 3, at least leaving a circle does not have externally threaded shaft 2, forms groove 5; On groove 5, be arranged with the seal ring of coupling; The tail end of described shaft 2 is also extended with one section does not have externally threaded shaft 2 for position-limited lever 6.
When described straight knurling 4 is multi-turn, its external diameter size is different, and from head 1 toward caudal directions, external diameter reduces gradually.Such design, packs in the tapped hole of wheel hub with patting to coordinate can facilitate bolt to install time.And the magnitude of interference that the external diameter of ladder-type can make mounting hole coordinate with boss bolt annular knurl place reduces amplitude and reduces, and extends the working life of boss bolt.
Described outside thread 3 outsides are coated with sealant layer.Can not get rusty in the junction that can ensure like this bolts and nuts.
The end face edge place of described position-limited lever 6 is set to chamfering.
