Embodiment
As Figure 1-Figure 4: a kind of rear tyre bolt, comprise the cap section 1 connected successively, strengthening segment 2, changeover portion 3 and thread section 4, described cap section 1 is First Transition segmental arc 21 with the joint of strengthening segment 2, the radian of this First Transition arc end is π/12-π/10: if when the radian of First Transition segmental arc 21 is greater than π/12-π/10, increase the diameter of First Transition segmental arc 21, make to produce cost to improve, do not meet market, and increase the triviality of technique, if when the radian of First Transition segmental arc 21 is less than π/12-π/10, cap section 1 is caused to reduce with the join strength of strengthening segment 2, and the internal force that First Transition segmental arc 21 produces reduces, when cap section 1 rotates, First Transition segmental arc 21 easily stress deformation or crack.
Strengthening segment 2 is connected by the First stage 5 with changeover portion 3, the perisporium in described First stage 5 takes the form of inclined plane, described changeover portion 3 comprises the second transition segmental arc 31 and extension 32, two terminations of described second transition segmental arc 31 are connected with First stage 5 and extension 32 respectively, and the second transition segmental arc 31 to taper off shape from First stage to the diameter adding extension 32, the radian of this second transition segmental arc 31 is π/6-π/4: if when the radian of the second transition segmental arc 31 is greater than π/6-π/4, increase the diameter of the second transition segmental arc 31, make to produce cost to improve, do not meet market, and increase the triviality of technique, if when the radian of the second transition segmental arc 31 is less than π/6-π/4, changeover portion 3 is caused to reduce with the join strength of step section, antitorque and the anti-pressure ability of the second transition segmental arc 31 reduces greatly.
First stage 5 and strengthening segment 2 are formed strengthens angle 23, and the angle at this reinforcement angle 23 is 9 °-11 °; Described cap section 1 comprises outer section 11 and inner segment 12, and the outer wall of described outer section 11 is provided with the stress arc 10 improving outer section 11 internal force, and the radian of this stress arc 10 is π/9-π/7: if when the radian of stress arc 10 is π/9-π/7, and the impact resistant capability of outer section 11 is best.Described thread section 4 comprises interconnective linkage section 41 and second step section 42, and this second step section 42 takes the form of inclined plane, described linkage section 41 is provided with screw thread, the diameter of described strengthening segment 2 and the diameter ratio of thread section 4 are 1.1-1.3, the diameter of described thread section 4 is greater than the diameter of changeover portion 3, the ratio of the diameter of described cap section 1 and the diameter of thread section 4 is 1.3-1.5: if when the ratio of the diameter of the diameter of cap section 1 and thread section 4 is greater than 1.3-1.5, the diameter of cap section 1 increases the waste causing material, improve generation cost, do not meet the demand in market, if when the ratio of the diameter of the diameter of cap section 1 and thread section 4 is less than 1.3-1.5, the diameter minimizing of cap section 1 causes the moment of torsion of cap section 1 to reduce, gruelling when turncap section 1.
