Description

A kind of preceding sprung shock-strut seat assembly

Technical field

The utility model relates to chassis technology fields, more particularly to a kind of preceding sprung shock-strut seat assembly.

Background technique

With the rapid development of the automotive industry, people to automobile environmental protection, comfort, in terms of requirement it is more next It is higher.With spring parallel arrangement damper can reduce Uneven road or driving status variation excitation on vehicle body caused by rise Vibration and rear vibration, the caused vibration on wheel of rapid decay road excitation.The primary structure of McPherson strut is by helical spring It is formed with damper, when vehicle passes through uneven road surface, spring, buffer stopper and damper are compressed, and pass through vibration damping branch Column base assembly is transmitted to vehicle body.Preceding sprung shock-strut seat assembly as damper and vehicle body connecting medium, need to have use intensity and Performance requirement, at present there are two types of used structure types: single channel form, binary channels form, such preceding sprung shock-strut seat are total It is had the following problems at structure:

1. single pass preceding sprung shock-strut seat assembly: as depicted in figs. 1 and 2,06 main structure of rubber bushing is simultaneously by piston The effect of the buffer stopper power on absorber damping force, buffer stopper 02 on bar 01 and the spring force on spring 03, eventually by branch Column base assembly 04 is transmitted to vehicle body 05.Rubber bushing 06 preloads big, durable reliability requirement height, it is difficult to guarantee that performance adjustment is wanted It asks.

2. twin-channel preceding sprung shock-strut seat assembly: as shown in Figure 3 and Figure 4,006 main structure of rubber bushing is by piston rod The effect of the buffer stopper power on absorber damping force and buffer stopper 002 on 001,006 auxiliary structure of rubber bushing is by spring 003 Spring-force driven dual is transmitted to vehicle body 005 eventually by pillar seat assembly 004.It is compared with single channel form, rubber bushing 006 is pre- Load is smaller, and durable reliability requires lower.But since rubber bushing 006 and pillar seat assembly 004 are vulcanization integral structure, whole Vehicle performance adjustment stage, the change of 006 structure of rubber bushing may cause the variation of pillar seat assembly 004, and part fabrication cycle is long, difficult To meet project process, the optional range of performance adjustment is small.

3. as shown in Figure 2 and Figure 4, the material of the preceding sprung shock-strut seat assembly horizontal wall in single, double channel is punching press steel, matter Amount is big, it is difficult to realize the lightweight target of vehicle.

4. as shown in Figure 2 and Figure 4, the preceding sprung shock-strut seat assembly in single, double channel passes sequentially through punching press, welding, vulcanization, rotation Riveter skill is realized, needs to reduce the influence of Pressing Deformation, welding deformation, vulcanization deformation and rotation riveting deformation to horizontal wall flatness.

5. as shown in figures 1 and 3, single pass preceding sprung shock-strut seat assembly is difficult to solve in pillar seat assembly 04 and vehicle body The wall abnormal sound problem adjoint due to face contact unbalance stress, twin-channel preceding sprung shock-strut seat assembly are difficult to solve pillar seat assembly 004 with the vehicle body inner wall abnormal sound problem adjoint due to face contact unbalance stress.

6. as shown in Figure 2 and Figure 4, the performance curve of single pass preceding sprung shock-strut seat assembly once it is determined that, in short cycle It is inside difficult to individually change 06 structure of rubber bushing realization performance curve linear section, the adjustment target of changeover portion, subtract before twin-channel Shake pillar seat assembly performance curve once it is determined that, be difficult to individually to change 006 structure of rubber bushing realization performance in short cycle Curve linear section, the adjustment target of changeover portion.
