The rubber bushing 06 is large in preload, high in durability and reliability requirements and difficult to guarantee performance debugging requirements.
2. The preceding damping pillar seat assembly of binary channels: as shown in fig. 3 and 4, the primary structure of the rubber bush 006 is acted by the damping force of the shock absorber on the piston rod 001 and the damping force of the damping block on the damping block 002, and the secondary structure of the rubber bush 006 is acted by the spring force of the spring 003, and finally transmitted to the vehicle body 005 through the strut seat assembly 004. Rubber bushing 006 is less preloaded and less critical to endurance reliability than in the single pass version. However, since the rubber bushing 006 and the strut seat assembly 004 are of a vulcanization integrated structure, in the whole vehicle performance debugging stage, the structural change of the rubber bushing 006 may cause the change of the strut seat assembly 004, the part manufacturing period is long, the project schedule is difficult to meet, and the performance debugging selectable range is small.
3. As shown in fig. 2 and 4, the horizontal wall of the single-channel and double-channel front damping strut seat assembly is made of stamping steel, so that the weight of the whole vehicle is difficult to achieve.
4. As shown in fig. 2 and 4, the single-channel and double-channel front damping strut seat assembly is realized through processes of stamping, welding, vulcanizing and spin riveting in sequence, and the influence of stamping deformation, welding deformation, vulcanizing deformation and spin riveting deformation on the flatness of the horizontal wall needs to be reduced.
5. As shown in fig. 1 and 3, the single-channel front vibration damping strut seat assembly is difficult to solve the abnormal sound problem caused by the uneven surface contact stress between the strut seat assembly 04 and the inner wall of the vehicle body, and the double-channel front vibration damping strut seat assembly is difficult to solve the abnormal sound problem caused by the uneven surface contact stress between the strut seat assembly 004 and the inner wall of the vehicle body.
6. As shown in fig. 2 and 4, once the performance curve of the single-channel front damping strut mount assembly is determined, it is difficult to individually modify the structure of the rubber bushing 06 in a short period to achieve the adjustment target of the linear section and the transition section of the performance curve, and once the performance curve of the dual-channel front damping strut mount assembly is determined, it is difficult to individually modify the structure of the rubber bushing 006 in a short period to achieve the adjustment target of the linear section and the transition section of the performance curve.
