Description
Technical field
The utility model belongs to field of automobile suspension, specifically refers to a kind of hydraulic mount.
Background technique
For engine side suspension, in order to improve its anti-vibration performance in high frequency, be generally all designed to hydraulic mount, its Specifeca tion speeification of hydraulic mount to have under dynamic stiffness under the output ratio of Q-switching to free running and high frequency, low frequency large damping etc.In general, what affect the output ratio of Q-switching to free running is decoupling zero mambrane tension, and what affect the dynamic stiffness under high frequency is flow-disturbing dish.Therefore, select Low rigidity decoupling zero diaphragm to be conducive to obtaining the less output ratio of Q-switching to free running, be beneficial to isolation high frequency small amplitude motion.But general its endurance quality of Low rigidity decoupling zero diaphragm is lower, especially for cross-country type vehicle, road conditions are severe, hydraulic mount inner decoupling zero diaphragm breakage phenomenon can occur more.After breakage, though the output ratio of Q-switching to free running is lower, low frequency damping and gum close, lose hydraulic mount function.Therefore, restrict by endurance quality, Low rigidity decoupling zero diaphragm SUV, MPV vehicle use and inapplicable.
Dynamic stiffness: relative to the definition of Static stiffness, Static stiffness refers to the deformation quantity that object produces under certain External Force Acting, and dynamic stiffness is then the deformation quantity that object produces under the External Force Acting under certain frequency.
The output ratio of Q-switching to free running: the ratio of dynamic stiffness and Static stiffness.
As depicted in figs. 1 and 2, for the suspending soft cushion assembly on SUV power assembly, comprise the suspending cushion be made up of rubber spring 1, suspension purchasing ore 5, runner 4, platen 3, decoupling zero diaphragm 7, flow-disturbing dish 2, bed die 6, isolated by decoupling zero diaphragm 7 between upper liquid chamber 8 and lower liquid chamber, the circulation between liquid chamber is realized by runner 4, when low frequency large amplitude, liquid directly circulates at upper liquid chamber 8 and lower liquid chamber via runner 4, the fluid resistance now produced through small channel by liquid stream is comparatively large, is the main contributions element producing low frequency damping; Under engine idle and high-speed working condition, because amplitude is less, frequency is very fast, liquid almost effectively cannot flow in runner, only has the volume-variation being realized upper and lower liquid chamber by the distortion of decoupling zero diaphragm, therefore the rigidity of decoupling zero diaphragm has just become impact now to suspend the key factor of dynamic stiffness, and the thickness of decoupling zero diaphragm, size and structure and rubber material are the principal element places affecting its performance, decoupling zero mambrane tension is low, and dynamic stiffness is little.Therefore thin, that hardness is low decoupling zero diaphragm, can obtain lower dynamic stiffness, but its endurance quality is poor, easily occurs disrepair phenomenon.
The shortcoming of this technological scheme is:
1) general this kind of structure decoupling diaphragm, for being pressed between platen and runner, generally its inner metal-containing skeleton, decoupling zero mambrane tension is comparatively large, and therefore, the output ratio of Q-switching to free running is comparatively large, is unfavorable for isolation high frequency small amplitude motion.Such as: time 25Hz (for four-cylinder, during idling 750rpm, the second order energizing frequency of motor), the output ratio of Q-switching to free running under certain amplitude is comparatively large, and be unfavorable for vibration when isolating engine idle, other higher frequencies are also like this.
2) though this kind of decoupling zero mambrane tension is larger, its endurance quality is good, but increases along with vehicle travels the severe degree of road conditions, and service time is longer, decoupling zero diaphragm still occurs Some vehicles damages, the vibration of power assembly when being unfavorable for isolating low frequency (especially 10-13Hz).
For overcoming the shortcoming of existing technology, technology has now been had to propose improvement opportunity scheme, namely the suspending soft cushion assembly on existing MPV power assembly is divided into two classes, one class uses gum suspension, another kind of is close with the suspending soft cushion assembly on existing SUV power assembly, is only be provided with cross recess on decoupling zero diaphragm.
And such improvement still Shortcomings part:
For gum suspension, there is dynamic hardening phenomenon in (1) high frequency, is unfavorable for the vibration of isolation high frequency small amplitude; (2) during low frequency, damping is little, is unfavorable for isolation low frequency Large Amplitude Vibration.
For hydraulic mount (decoupling zero diaphragm exists otch), due to otch, when can cause low frequency, damping is less, is unfavorable for isolation low frequency Large Amplitude Vibration.
