Background
With the rapid development of the automobile industry, people have increasingly high requirements on the aspects of environmental protection, comfort, reliability and the like of automobiles. The vibration damper arranged in parallel with the springs can reduce the starting vibration and the rear vibration caused by the excitation of uneven road surface or running state change on the vehicle body, and quickly attenuate the vibration caused by the excitation of the road surface on the wheels. The main structure of the macpherson suspension consists of a coil spring and a shock absorber, and when a vehicle passes through an uneven road surface, the spring, the buffer block and the shock absorber are compressed and transferred to the vehicle body through a shock absorption strut seat assembly. The front vibration reduction strut seat assembly is used as a medium for connecting a vibration damper with a vehicle body, and is required to have the requirements of use strength and performance, and the currently used structural forms have two types: the front vibration reduction strut seat assembly structure has the following problems in a single-channel mode and a double-channel mode:
1. Front vibration reduction strut seat assembly of single channel: as shown in fig. 1 and 2, the main structure of the rubber bushing 06 is simultaneously subjected to the damper damping force on the piston rod 01, the damper force on the damper block 02 and the spring force on the spring 03, and finally transmitted to the vehicle body 05 through the strut seat assembly 04. The rubber bushing 06 has large preload and high durability and reliability requirements, and is difficult to ensure the performance debugging requirements.
2. Double-channel front vibration reduction strut seat assembly: as shown in fig. 3 and 4, the main structure of the rubber bushing 006 is acted by the damping force of the damper on the piston rod 001 and the buffer block force on the buffer block 002, and the auxiliary structure of the rubber bushing 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. The rubber bushing 006 has less preload and lower endurance reliability requirements than 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 progress 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 vibration reduction strut seat is made of punched steel, has large mass, and is difficult to achieve the aim of light weight of the whole vehicle.
4. As shown in fig. 2 and fig. 4, the single-channel and double-channel front vibration reduction strut seat assembly is realized through stamping, welding, vulcanizing and spin riveting processes in sequence, and the influence of stamping deformation, welding deformation, vulcanizing deformation and spin riveting deformation on the flatness of the horizontal wall is required to be reduced.
5. As shown in fig. 1 and 3, the single-channel front vibration reduction strut seat assembly is difficult to solve the problem of abnormal sound caused by uneven surface contact stress between the strut seat assembly 04 and the inner wall of the vehicle body, and the dual-channel front vibration reduction strut seat assembly is difficult to solve the problem of abnormal sound caused by 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 vibration reduction strut seat assembly is determined, it is difficult to independently change the rubber bushing 06 structure to achieve the adjustment targets of the performance curve linear section and the transition section in a short period, and once the performance curve of the double-channel front vibration reduction strut seat assembly is determined, it is difficult to independently change the rubber bushing 006 structure to achieve the adjustment targets of the performance curve linear section and the transition section in a short period.
