Skeleton, can promote the fatigue strength of suspending soft cushion assembly, reduces stress and concentrates and evaded core pipe cracking leakage of oil risk, improves
Security performance；The anti-vibration performance of suspension can be promoted again, car load NVH performance is had obvious benefit.
Further, being provided with the bumper of cage or case structure in described lower limit panel beating, described bumper is by trailing arm
The end encirclement the interference fit that are positioned at lower limit panel beating collide generation metal abnormal sound with prevention trailing arm and panel beating support.
Further, in described lower limit panel beating, it is fixed with the spacing panel beating of Y-direction of slab construction in the lower section of bumper,
The middle part of the spacing panel beating of described Y-direction is provided with through hole, for limiting the trailing arm movement in Y-direction, thus controls the displacement of electromotor,
Above-mentioned through hole is the space passed through for the used tool that tights a bolt.
Further, described lower limit panel beating, panel beating support, lower welding bottle and the spacing panel beating of Y-direction are by the side of welding
Formula links together, to provide enough intensity and mode.
Further, described bottle is connected by riveting method or interference fit are fixing with lower welding bottle, with convenient
Assembling.
The tubular pull-down hydraulic suspension structure of the present invention is compact simply, and overall structure uniform force is reasonable, has preferably
Fatigue properties, all directions have well vibration decay and position-limiting action, can be carried out three-way rigidity well designing,
Regulation, has a good vibration damping capacity reaching three-dimensional, promotes car load NVH performance；Each direction has the most spacing
Form, it is possible to well limit the over-large displacement of power assembly, reduces the impact to power assembly of the passenger compartment enteroception, improves outstanding
Put the service life of cushion.
