Abstract
The utility model relates to a rim bolt, including the body of rod (1), body of rod both ends are equipped with respectively soon to opposite external screw thread (1a), and body of rod middle part is equipped with polished rod (1b), is equipped with the 1st annular table rank (3) on its characterized in that polished rod. The utility model discloses beneficial effect lies in simple structure, when increase rim bolt takes the bearing surface of brake drum with wheel hub, has prevented further that rim bolt from taking the brake drum to rotate and the translation for rim, wheel hub to adopt one -shot casting, strengthened its bearing capacity greatly.
Description
Technical field
This utility model relates to a kind of securing member, particularly relates to a kind of rim bolt.
Background technology
Rim bolt, as wheel hub band brake drum assembly and the connector of rim for automobile wheel, needs the big torsion undertaking between automotive hub with axletree to be connected, so having higher requirement the bearing capacity between screw rod and assembly precision.The bearing-surface of the rim bolt under prior art is less, once assemble not in place, in actual use rim bolt will relative to wheel hub band brake drum rotate, thus cause whole rim bolt to fracture, wheel comes off, and causes the serious accident of automobilism.
Goal of the invention
The technical problem that rim bolt bearing-surface that the purpose of this utility model is to solve under prior art is little, and a kind of rim bolt is provided.
The purpose of this utility model is achieved by the following technical programs:
A kind of rim bolt, including the body of rod, the body of rod is respectively arranged at two ends with oppositely oriented external screw thread, is provided with polished rod in the middle part of the body of rod, it is characterised in that polished rod is provided with first annular step.
During use, the rim bolt hole of the first annular step of the body of rod and wheel hub band brake drum excessively coordinates, by setting up first annular step in the middle part of the body of rod, with and increase in the middle part of the body of rod contact area with rim bolt hole, increase bearing-surface.
The cross section of described first annular boss is rectangle, and this cross section is mutually perpendicular to the axis place plane of first annular boss, prevents the body of rod from rotating relative to wheel rim, wheel hub band brake drum further with this.
The cross section of described first annular boss is circular, and this cross section is mutually perpendicular to the axis place plane of first annular boss.
Described first annular step is provided with the second ring-shaped step, increases the contact area of the body of rod and the rim bolt hole of wheel hub band brake drum with this further, expands bearing-surface, prevents the body of rod to move along its axis in the rim bolt hole of wheel hub band brake drum.
The cross section of described second annular boss is rectangle, and this cross section is mutually perpendicular to the axis place plane of the second annular boss, prevents the body of rod from rotating relative to wheel rim, wheel hub band brake drum further with this.
The cross section of described second annular boss is circular, and this cross section is mutually perpendicular to the axis place plane of the second annular boss.
This utility model has the beneficial effects that simple in construction, while increasing rim bolt and the bearing-surface of wheel hub band brake drum, prevent rim bolt to rotate and translation relative to wheel rim, wheel hub band brake drum, and use one-step casting molding further, greatly strengthen its bearing capacity.
The most just the utility model is described in further detail for accompanying drawings and embodiment.

Detailed description of the invention
Embodiment 1
As shown in Figures 1 and 2, a kind of rim bolt provided for this utility model, including the body of rod 1, the body of rod is respectively arranged at two ends with oppositely oriented external screw thread 1a, polished rod 1b it is provided with in the middle part of the body of rod, polished rod is provided with the first annular step 3 being coaxial therewith coordinating, the cross section of first annular boss 3 is rectangle, this cross section is mutually perpendicular to the axis place plane of first annular boss, described first annular step 3 is provided with the second ring-shaped step 2 being coaxial therewith coordinating, the cross section of the second annular boss 2 is rectangle, and this cross section is mutually perpendicular to the axis place plane of the second annular boss.
Embodiment 2
As shown in Figures 3 and 4, a kind of rim bolt provided for this utility model, including the body of rod 1, the body of rod is respectively arranged at two ends with oppositely oriented external screw thread 1a, polished rod 1b it is provided with in the middle part of screw rod, polished rod is provided with the first annular step 3 being coaxial therewith coordinating, the cross section of first annular boss 3 is circular, this cross section is mutually perpendicular to the axis place plane of first annular boss, described first annular step 3 is provided with the second ring-shaped step 2 being coaxial therewith coordinating, the cross section of the second annular boss 2 is circular, and this cross section is mutually perpendicular to the axis place plane of the second annular boss.
Use assembling
When wheel hub band brake drum assembly is assembled with wheel rim, as shown in Figure 5, after the body of rod 1 one end of the present utility model is passed wheel hub 7, being fastenedly connected with locking nut 4, the most first annular boss 3 one sections and the second annular boss 2 all excessively coordinate with the first wheel rim bolt hole 7a；The body of rod other end sequentially passes through brake drum 6 and wheel rim 5 again, and now first another section of boss 3 excessively coordinates with the second rim bolt hole 6a of brake drum 6, and the described body of rod other end, after the third round rim bolt hole 5a of wheel rim 5 passes, is fastenedly connected by locking nut 4.
