The left double-inclined-surface anti-heel-turn structure 8 comprises a left anti-heel-turn structure and a right anti-heel-turn structure, wherein the left anti-heel-turn structure 8-1 and the right anti-heel-turn structure 8-2 are of inclined-surface structures, the left anti-heel-turn structure 8-1 and the right anti-heel-turn structure 8-2 are connected with the steering engine shell 1 at the bottom, the left anti-heel-turn structure 8-1 and the right anti-heel-turn structure 8-2 are obliquely arranged at the inner side of the left threaded rubber mounting bushing 4, and a middle hollowing area 8-3 is arranged between the left anti-heel-turn structure 8-1 and the right anti-heel-turn structure 8-2.
The left anti-heel-turn structure 8-1 and the right anti-heel-turn structure 8-2 are arranged in a V-shaped direction, and the inclination angles of the left anti-heel-turn structure 8-1 and the right anti-heel-turn structure 8-2 and the horizontal plane are 2.7 degrees.
The structure of the left side mounting bracket 2 is identical to that of the right side mounting bracket 3.
The left side installing support 2 is a metal framework, and a threaded hole 2-1 connected with a left side threaded rubber installing bushing 4 is longitudinally formed in the middle of the left side installing support 2.
The structure of the left-hand thread rubber mounting bush 4 corresponds to the structure of the right-hand thread rubber mounting bush 6.
The structure of the left rubber mount bushing 5 is identical to that of the right rubber mount bushing 7.

The left double-inclined-surface heel-turning preventing structure 8 is divided into three parts, namely a left heel-turning preventing structure 8-1, a middle hollowed-out area 8-3 and a right heel-turning preventing structure 8-2. The left side anti-follow-up structure 8-1 and the right side anti-follow-up structure 8-2 are both inclined structures, because the left side thread rubber installation bushing 4 and the right side thread rubber installation bushing 6 are in the process of assembling and bolting, as the bolt tightening torque is increased, the interference magnitude of the threaded holes 2-1 of the left side thread rubber installation bushing 4 and the left side installation bracket 2 is insufficient to overcome the bolt tightening torque, at the moment, the left side thread rubber installation bushing 4 can rotate around the bolt as the center along with the bolt tightening direction, because the outermost part of the left side thread rubber installation bushing 4 is firstly contacted with the left side double-inclined-surface anti-follow-up structure 8 when the left side thread rubber installation bushing 4 rotates, as the tightening torque is increased, the outermost part rubber of the left side thread rubber installation bushing 4 can be compressed and deformed, so that the left side thread rubber installation bushing 4 continues to rotate, until the outermost part of the left-hand thread rubber mounting bush 4 is completely compressed, the metal skeleton of the left-hand mounting bracket 2 is in contact with the left-hand double-inclined-surface anti-follow-rotation structure 8, at this time, the left-hand thread rubber mounting bush 4 is already limited by the left-hand double-inclined-surface anti-follow-rotation structure 8, this position is the maximum rotation angle of the left-hand thread rubber mounting bush 4, the thicker the thickness of the outer vulcanized rubber layer 4-1 of the left-hand thread rubber mounting bush 4 is, the greater the rotation angle of the left-hand thread rubber mounting bush 4 is, the more unfavorable the anti-follow-rotation structure is, the left-hand thread rubber mounting bush 4 is in line contact with the anti-follow-rotation plane of the left-hand double-inclined-surface anti-follow-rotation structure 8, because the left-hand thread rubber mounting bush 4 is deflected by a large angle, the outermost part of the left-hand thread rubber mounting bush 4 is in line contact with the anti-follow-rotation boss of the left-hand double-inclined-surface anti-rotation structure 8, the middle part of the left side thread rubber mounting bushing 4 is not contacted with the anti-follow-rotation boss, so that the anti-follow-rotation boss is only subjected to a small part of contact stress, and the anti-follow-rotation boss cannot bear along with the increase of the tightening torque, so that the anti-follow-rotation boss is damaged and fails.
Therefore, the left side anti-follow-up structure 8-1 and the right side anti-follow-up structure 8-2 are designed into inclined structures, in order to combine the left side thread rubber mounting bush 4 to be easy to generate extrusion deformation in the disassembling and screwing process, in order to compensate for larger angle deflection of the left side thread rubber mounting bush 4 caused by the rubber deformation, so that the contact area of the left side double inclined surface anti-follow-up structure 8 and the left side thread rubber mounting bush 4 is reduced, the contact area of the left side thread rubber mounting bush 4 and the left side double inclined surface anti-follow-up structure 8 is increased from the design optimization of the left side double inclined surface anti-follow-up structure 8, the left side anti-follow-up structure 8-1 and the right side anti-follow-up structure 8-2 are designed into inclined angles of 2.7 degrees, the angles are calculated through the thickness of 0.6mm of the outer ring vulcanized rubber layer 4-1 of the left side thread rubber mounting bush 4, the outer ring vulcanized rubber layer 4-1 of the left side thread rubber mounting bush 4 is completely extruded and deformed with the screw thread as a center, and the screwing torque is increased. The left double-inclined-surface anti-heel-turn structure 8 is an inclined surface from top to bottom when seen from the side surface of the left anti-heel-turn structure 8-1, and meanwhile, the inclined surface of the rib extends all the time to be connected with the steering gear shell 1, so that the rigidity of the steering gear shell 1 is increased, and the bending resistance and the torsion resistance of the whole rib are very strong.
The design principle of the right side thread rubber mounting bush 6 and the right side double-inclined-surface anti-heel-turning structure 9 is consistent with the design principle and the structure of the left side thread rubber mounting bush 4 and the left side double-inclined-surface anti-heel-turning structure 8.
Example 1: in the process of screwing and disassembling a bolt, the interference fit of the left threaded rubber mounting bush 4 and the threaded hole 2-1 of the left mounting bracket 2 is insufficient to overcome the screwing torque in the screwing process of the bolt, when the screwing torque of the bolt reaches 100Nm, the left threaded rubber mounting bush 4 rotates around the bolt, the outermost part of the left threaded rubber mounting bush 4 is in contact with the anti-rotation structure, the outer ring vulcanized rubber layer 4-1 of the left threaded rubber mounting bush 4 is extruded and deformed along with the increase of the screwing torque, the left threaded rubber mounting bush 4 can continue to rotate until the outer ring vulcanized rubber layer 4-1 is extruded and deformed, the outermost metal framework of the left threaded rubber mounting bush 4 is in contact with the left double-inclined-surface anti-rotation structure 8, the position is the maximum deflection angle of the left threaded rubber mounting bush 4, and in the screwing and disassembling the bolt process, the left threaded rubber mounting bush 4 and the left double-inclined-surface anti-rotation structure 8 are in contact with one half of the left threaded rubber in the screwing and disassembling the bolt. Considering that the middle hollowed-out area 8-3 and the left threaded rubber mounting bushing 4 are not contacted in the disassembling and screwing processes, and simultaneously, in combination with the casting requirements of parts of suppliers, excessive and excessively thick materials are piled up, bubbles and sand holes can be generated in the left double-inclined-surface anti-heel-turn structure 8, so that defects exist in the left double-inclined-surface anti-heel-turn structure 8, the middle hollowed-out area 8-3 is formed between the left anti-heel-turn structure 8-1 and the right anti-heel-turn structure 8-2, the realization of the casting process of suppliers is facilitated, and the defect that the strength of the anti-heel-turn structure is insufficient due to casting defects is reduced. Meanwhile, the product requirement is met, the casting defect that shrinkage cavity or looseness is caused by too thick part is avoided, and the strength of the left anti-follow-up rotation structure 8-1 and the right anti-follow-up rotation structure 8-2 can meet the requirement of 250 Nm+/-38 Nm of a customer after CAE analysis.
Example 2: because the thickness of the outer ring vulcanized rubber layer 4-1 of the left threaded rubber mounting bush 4 is thicker and more unfavorable for the left double-inclined-surface anti-follow-up structure 8, the interference fit amount of the threaded holes 2-1 of the left threaded rubber mounting bush 4 and the left mounting bracket 2 is insufficient to overcome the screwing torque of the bolt in the screwing process of the bolt, when the screwing torque of the bolt reaches 100Nm, the left threaded rubber mounting bush 4 rotates around the bolt, the outermost part of the left threaded rubber mounting bush 4 is firstly contacted with the left double-inclined-surface anti-follow-up structure 8, the outer ring vulcanized rubber layer 4-1 at the outermost side of the left threaded rubber mounting bush 4 is extruded and deformed along with the increasing screwing torque, the left threaded rubber mounting bush 4 continues to rotate until the extrusion deformation of the outer ring vulcanized rubber layer 4-1 at the outermost side is completed, the position of the left threaded rubber mounting bush 4 is the left double-inclined-surface anti-follow-up structure 8, the left threaded rubber mounting bush 4 generates the largest deflection angle in the actual assembly process, the left threaded rubber mounting bush 4 is deflected by a large angle beyond the left threaded rubber mounting bush 4, the left threaded rubber mounting bush is not contacted with the left double-inclined-surface anti-follow-up structure 8, the left threaded rubber mounting bush 4 is stressed by the same plane as the left threaded rubber mounting bush 4 is compressed and deformed by the left threaded rubber mounting bush 4, the left threaded rubber mounting bush is compressed and deformed by the left threaded rubber mounting bush 4 is deformed by the left rubber mounting structure, the left threaded rubber mounting bush 4 is deformed by the left threaded rubber mounting 4, and the left threaded rubber mounting bush is deformed by the left threaded rubber mounting 4, and left threaded rubber mounting bush is deformed by the left threaded rubber mounting nut, and left threaded rubber mounting nut is screwed by the left threaded rubber mounting nut. Because the contact area is reduced, the left double-inclined-surface anti-follow-up structure 8 bears the sharp rise of pressure, and therefore, the local position of the left double-inclined-surface anti-follow-up structure 8 starts to generate cracks and finally breaks, because the thickness of the outer vulcanized rubber layer 4-1 of the left threaded rubber mounting bush 4 does not influence the axial rigidity and the radial rigidity of customers, but the thickness of the outer vulcanized rubber layer 4-1 of the left threaded rubber mounting bush 4 is the technological requirement of suppliers, certain rubber is required to be reserved for meeting the technological requirement of the suppliers, and therefore, the thickness of the outer vulcanized rubber layer 4-1 of the left threaded rubber mounting bush 4 is designed to be 0.6mm under the calculation of CAE, the technological requirement of the suppliers is not influenced, and the large angle deflection of the left threaded rubber mounting bush 4 due to the rubber extrusion deformation in the screwing process can be reduced, so that the left threaded rubber mounting bush 4 and the left double-inclined-surface anti-follow-up structure 8 have enough contact area for better assurance.
According to the utility model, in combination with the assembly process of the client steering engine assembly, the outer ring rubber of the rubber mounting bushing can be extruded and deformed, and the rubber mounting bushing is subjected to large-angle deflection. The original scheme integrated parallel anti-follow-up structure is changed into a separate inclined anti-follow-up structure by optimizing the anti-follow-up structure of the steering engine shell and the thickness of the rubber of the outer ring of the threaded rubber mounting bushing; meanwhile, the thickness of the rubber of the outer ring of the threaded rubber mounting bushing is changed from 3mm to 0.6mm, and the rubber thickness is reduced, because the thicker the rubber thickness is, the larger the extrusion deformation of the threaded rubber bushing is in the assembly process, and the larger the deflection angle is. The anti-follow-up structure is more unfavorable, so that the problem of anti-follow-up failure caused by large-angle slip of the threaded rubber mounting bushing can be limited.
