Boss bolt is the high-strength bolt of vehicle connection wheel.Link position is the hub unit bearing of wheel, generally In minicar is 10.9 grades, and large and medium-sized vehicle uses 12.9 grades, and the structure of boss bolt is usually annular knurl key shelves, screw thread shelves With a cap head, T connector portion boss bolt is mostly 8.8 grades of ratings above, and the big torsion undertaken between automotive hub and axle connects It connects, double head type boss bolt is mostly 4.8 grades of ratings above, undertakes the company of lighter torsion between automobile foreign steamer hub shell and tire It connects, the hub bearing of car goes over most to be to use single-row tapered roller or ball bearing in pairs.With the development of technology, car Widely use car hub unit.
The axle hub wheel bolt of present heavy-duty car, structure is mostly the shaft between the head of bolt and thread segment It is processed as polished rod, this wheel bolt is pressed into the bolt hole on hub for vehicle wheel in interference fit when installation, and wheel bolt Head is fabricated to the round seam allowance cooperation rotation stop on milling flat and wheel hub, but the wheel bolt rotation stop effect of this structure is not It is good, wheel bolt rotation is will appear after nut fastening, or even occur after wheel bolt rotates that the plane seam allowance on wheel hub is serious The phenomenon that abrasion deformation, makes Joint failure.And in the operating process of fastening, if it cannot be guaranteed that the vertical strength of bolt and threaded hole It lacks experience so as to cause oblique loading or operating personnel or firmly excessive, fragile threaded hole stripped thread can be caused.
In addition it after boss bolt is mounted on automotive wheel, exposes for a long time in air, the rainy season of especially moist moistening Normal damage of getting rusty, influences bolt service life, increases maintenance replacement cost.
【Invention content】
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of rotation stop formula boss bolt is provided, ensure that Bolt vertical stress in fastener cycle reduces the probability of screw thread stripped thread, easy for assemble or unload, simple in structure, fastening stability Wheel hub cambered surface will not be cut when good and assembly, the stability of connection is improved by changing the shape of existing cylindrical bolt head, Will not rotate and loosen after bolt fastening, at the same on bolt head rotation prevention portion stabilizers globoidal structure, enable bolt head preferably and Wheel hub cambered surface is coincide, and bolt is not easy rotation damage wheel bore, will not cut wheel hub contacting surface.Good water resistance avoids Bolt gets rusty damage due to by rain erosion, extends bolt service life.
To achieve the above object, the present invention proposes a kind of rotation stop formula boss bolt, including bolt head mechanism, link block and The link block of screw mechanism, the bolt head mechanism and lower section passes through press bed stamping riveting, the link block and lower section Screw mechanism by press bed stamping riveting, the bolt head mechanism includes bolt head base portion and bolt head rotation prevention portion, institute The left and right ends for the bolt head base portion stated are equipped with bolt head rotation prevention portion, and the bolt head base portion and bolt head rotation prevention portion are integrated Formula structure, the bolt head rotation prevention portion are equipped with stabilizers, and the stabilizers are cambered surface and the radian of stabilizers and connect Tactile wheel hub cambered surface matches.
Preferably, the front and rear sides face of the bolt head mechanism is plane, the left and right two of the bolt head mechanism Side is cambered surface, and the bolt head base portion is rectangular parallelepiped structure, longer sides and the screw mechanism phase of the bolt head base portion Mutually vertical, the link block is connected with the longer sides of bolt head base portion, the shorter edge and bolt head of the bolt head base portion Rotation prevention portion is connected.
Preferably, link block minimum point in the horizontal direction is in the horizontal direction most higher than bolt head rotation prevention portion Low spot.
Preferably, the screw mechanism includes upper linkage section, thread segment and guiding light bar segment, the upper connection Section, thread segment and guiding light bar segment are sequentially connected from top to bottom, and the upper linkage section, thread segment and guiding light bar segment are integrated Formula structure, with link block by press bed stamping riveting, the thread segment is equipped with outer spiral shell for the top of the upper linkage section The size of line, the guiding light bar segment is less than externally threaded interior tolerance diametral, and the lower end of the guiding light bar segment is equipped with six The bottom surface of side shape boss, the hexagon boss is equipped with screw-driver slot.
Preferably, the screw-driver slot is flat recess or cross recess.
Preferably, the bolt head base portion and bolt head rotation prevention portion cooperate and form one in the top of link block Umbrella blocked area, the umbrella blocked area block link block and screw mechanism in lower section.
Preferably, the surface layer of the bolt head mechanism is equipped with waterproof layer.
Beneficial effects of the present invention:Compared with prior art, a kind of rotation stop formula boss bolt provided by the invention, by changing Become the shape of existing cylindrical bolt head to improve the stability of connection, will not rotate and loosen after bolt fastening, while bolt head The globoidal structure of stabilizers on rotation prevention portion enables bolt head preferably to coincide with wheel hub cambered surface, and bolt is not easy rotation damage wheel hub Hole will not cut wheel hub contacting surface;By the way that the guiding polished rod less than bolt external thread diameter is arranged below screw mechanism Section is oriented to polished rod and carries out vertically-guided before bolt and threaded hole occlusion, ensure that the vertical stress of bolt, reduce screw thread and slide The probability of silk;It is cooperated by bolt head base portion and bolt head rotation prevention portion and is blocked in the top of link block one umbrella of formation Link block and screw mechanism are blocked in area, and rainwater is flowed down along the epitaxial surface of bolt head mechanism, prevents rainwater from penetrating into, and is kept away Exempt from bolt to get rusty due to by rain erosion damage, extends bolt service life, and the surface layer of bolt head mechanism is equipped with waterproof layer, into One step improves the waterproof rustless property of bolt;By the way that screw-driver slot is arranged in hexagon boss bottom surface, convenient disassembly, use is cleverer It is living.
