Abstract
The utility model relates to a special convenient dismountable screw bolt for a wheel of a vehicle, belonging to the technical field of the special screw bolt for the wheel of the vehicle. The special screw bolt is composed of a screw bolt, a large screw nut, a small screw nut and a shim, wherein both ends of a step can be directly connected with two bolt heads having different diameters to form the screw bolt, and the end parts of the bolt heads can be provided with screw threads. One end of the screw bolt step can be a plane surface and can be directly connected with one end of the blot head having a smaller diameter, and positioning through holes can be arranged on the bolt heads. The other end of the step can be a conical surface and can be connected with one end of the bolt head having a larger diameter. The external end head of the large screw nut can be provided with a tilting angle, the interior is provided with a ring groove, and one end of the small screw nut can be provided with a plurality of notches. The utility model has the advantages of simple production processes, reasonable design, high screw bolt intensity, high durability, convenient assembly and disassembly, etc., and is the ideal special convenient dismountable screw bolt for the wheel of the vehicle.
Description
The utility model relates to a kind of quick and convenient dismounting automotive wheel special bolt that is exclusively used in, and belongs to automotive wheel special bolt field.
Development along with society, vehicular transport had entered a new development phase already, the replacing of automotive wheel has been the technical matters that everybody pays close attention to, concerning chaufeur, more and more wants a kind of method of simple, quick, firm conveniently assemble and disassemble wheel to send out a developing of automobile industry to adapt to.The automobile specified bolt in past is to be made of two bolts, and this bolt ubiquity the processing technology complexity, and the dismounting operation is many during use, and bolt strength is not enough, fracture easily, and automobile change of wheels spended time on road is long, and is all dangerous to chaufeur and goods.
The purpose of this utility model provides and a kind ofly is made of automotive wheel special bolt for convenience detach jointly bolt, big nut, primary nut and pad.
The two ends that the purpose of this utility model provides a kind of pad have the conical surface of certain angle; The high-strength vehicle wheel special bolt that screw thread on the bolt head of bolt two ends and step have certain distance.
There is the Dou chamfering outer end, termination that the purpose of this utility model provides a kind of big nut, and internal heads has a ring recess, automotive wheel special bolt for convenience detach.
The purpose of this utility model provides and a kind ofly has anti-skidding positioning through hole at the little bolt cephalic par of special bolt diameter, and an end of stove bolt has the automotive wheel special bolt for convenience detach of several notches.
The purpose of this utility model realizes by following array structure: a kind of just automotive wheel special bolt of dismounting that is made of jointly bolt, big nut, primary nut and pad, it is characterized in that special bolt is directly to be connected with two bolt heads that diameter is different at step two ends, there is screw thread end at the bolt head, one end of bolt step is the plane, directly be connected with the little first end of bolt of diameter, the step other end is the conical surface, directly is connected with the big first end of bolt of diameter; The two ends of pad are the conical surface with certain angle; Screw thread and step on the bolt head of bolt two ends have certain distance; There is oblique chamfering the outer end, termination of big nut, and internal heads has a ring recess; The bolt cephalic par little at the special bolt diameter has anti-skidding positioning through hole, and an end of stove bolt has several notches.
During use, diameter is little in the automotive wheel special bolt bolt head (13) is inserted perforate on the wheel hub, again special washer (4) is inserted in the big bolt head (12) of diameter, make pad be in the centre of two wheel hubs, big primary nut (2,3) is tightened get final product again.Because of the two ends of special washer have the conical surface (16) of certain angle, can effectively prevent loosening between two automotive hubs during use; Screw thread (14) on the bolt head of bolt member two ends preferably has certain distance with bolt step (L), the intensity when levying special bolt and use with the guarantor and rupturing when preventing that special bolt from using; The oblique chamfering (21) of the outer end, termination of big nut (2) be for wheel nave on oblique chamfering surely close, prevent wheel loose on axle, it is can directly insert effectively in the wheel hub inclination angle for the Dou chamfering that makes the big nut front end that the big nut internal heads has a ring recess (22); Notch on the primary nut (31) is mainly used in and allows the locating dowel pin that inserts on the stove bolt through hole (17) pass, and prevents when special bolt from using loosening.
It is simple that the utility model automotive wheel special bolt has production technology, reasonable in design, bolt strength height, durable, advantages such as mounting or dismounting are convenient, can be according to the requirement of various different vehicle, producing the special bolt of different sizes and model, is a kind of automotive wheel special bolt desirable, for convenience detach.
