Description

A kind of tubular pull-down hydraulic mount
Technical field
The invention belongs to automobile power assembly suspension system technical field, it is more particularly related to can be effective Improve NVH performance and the mounting structure of fatigue behaviour.
Background technology
Along with the development of auto industry, the NVH performance of automobile is gradually paid close attention to by main engine plants and client, and NVH also becomes One of key factor that client considers when buying automobile.Power assembly suspension system is the bullet between power assembly and vehicle body Property connector, act primarily as and support power assembly weight, limit power assembly displacement under various operating modes, ensure that power assembly exists Relatively stable state, decay power assembly excitation it is in the vibration of vehicle body transmission, therefore suspension system under various operating modes Reliability and the comfortableness of automobile are had a direct impact by design quality, and mounting structure becomes the most also with increasing of vehicle Sample.
Summary of the invention
The purpose of the present invention is to propose to a kind of tubular pull-down hydraulic mount, to meet the various operating mode property to suspension system Can requirement.
The tubular pull-down hydraulic mount of the present invention is by lower limit panel beating, panel beating support, lower welding bottle, bottle, inertia Passage body, leather cup, decoupling film, rubber spring, core cannon born frame, connecting bolt, trailing arm are constituted;Described lower limit panel beating, lower welding Bottle, bottle be above and below the cup-like structure of opening, bottle, lower welding bottle, lower limit panel beating are nested the most solid successively Fixed connection, the lateral wall of lower limit panel beating is fixing with panel beating support to be connected;Rubber spring by sulfuration process by core cannon born frame with Bottle is connected as a single entity, and cup packing is passed through on the top of bottle;One end of trailing arm is through the sidewall of lower limit panel beating, and passes through to connect Bolt is fixing with the bottom of core cannon born frame to be connected;Described decoupling film is fixed in bottle by inertia channel body.
Suspending cushion realizes enough intensity and mode by lower limit panel beating, lower welding bottle, panel beating support, has foot Enough fatigue properties, it is ensured that skeleton does not ruptures under various operating modes;It addition, above-mentioned position limiting structure is to dynamic three total sides To displacement all have control, it is to avoid dynamic always excessive in the displacement of front deck, and its periphery member occurrence dynamics interference, occur other can not The risk of precognition.
Further, described inertia channel body is pressed together by interference fit by upper and lower two parts and forms inertia Passage;The lower part of inertia channel body is fixed in decoupling film sulfuration;Inertia channel body is provided with for connecting above inertia channel body With the compensation hole of lower section, described compensation hole together form decoupling passage with decoupling film;Decoupling film is spacing interior with inertia channel Mechanical clearance it is provided with between surface.When decoupling film displacement up or down is less than mechanical clearance, the rigidity of decoupling film is the least. The compensation hole that inertia channel body top is provided with is for reducing low frequency cavitation.Under the excitation of the big amplitude of low frequency, as rubber master When spring moves upward, due to viscosity and the inertia of liquid, have little time that epicoele is made flowing and compensate, then produce vacuum at epicoele Degree, produces cavitation, and using and compensating hole is the effective measures eliminating cavitation, but to sacrifice vibration isolation during the big amplitude of low frequency Ability is cost.
Further, described core cannon born frame is made up of the umbrella skeleton of the core pipe of lower section with top, described umbrella skeleton Sidewall is the bell mouth shape of opening upwards, and the top of umbrella skeleton is annular horizontal limit;The upper end sulfuration of described rubber spring is even Being connected to core tube side wall and the sidewall of umbrella skeleton, top end, the lower end sulfuration of rubber spring is connected at the medial wall of bottle.On State the core cannon born frame of structure to be preferably integrally machined and make, the core pipe made compared to traditional slab construction and core sealing of tube 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.
