Description
Technical field
The present invention relates to off highway vehicle chair art, particularly relate to a kind of off highway vehicle seat two dimension
Nonlinear isolation suspension.
Background technology
Off highway vehicle work under bad environment, driver bears multidimensional whole body vibration, works long hours continuously
Driver often perplexed by pain in the lumbar region, the disease such as have a back ache, have a strong impact on work efficiency and cause with regard to ancient Chinese medical classics
Ji loss is huge.Show according to epidemiological study, this pain in the lumbar region of off highway vehicle driver, have a back ache and ask
Inscribe and bear whole body vibration environment and have much relations.Therefore, off highway vehicle vibration control problem is always
One by the study hotspot of extensive concern.Seat is as last in off highway vehicle vibration transfer path
Ring, due to bump contact direct with driver, for slowing down whole body vibration effect that driver bears extremely
Close important.
Current off highway vehicle seat vibration isolation mainly uses the one-dimensional vertical side designed based on linear vibration isolation principle
To vibration isolation suspension, and vibration isolation area research personnel known linear vibration isolation principle anti-vibration performance in theory is limited,
Have that anti-vibration performance is good but contradiction that static displacement is big.For improving this contradiction of linear vibration isolation principle, research
Personnel, by non-linear introducing vibration isolation, develop nonlinear isolation device, as Yan Zhenhua etc. design based on positive and negative
The ultralow frequency vibration isolator of rigid spring parallel connection is i.e. based on nonlinear isolation principle design.It addition, there is research
Active, semi-active control technology are applied to seat suspension, external world's energy that the loss of this kind of suspension is certain by personnel
Source, and relatively costly.In general, for improving off highway vehicle seat anti-vibration performance, and consider economy
Sex chromosome mosaicism, the technology being presently most suitable for is that nonlinear isolation principle is introduced off highway vehicle seat suspension.
It addition, current off highway vehicle seat suspension is mainly one-dimensional vertical direction vibration isolation, and highway
There is multi-dimensional vibration during vehicle operation, multi-dimensional vibration causes driver's pain in the lumbar region, problem of having a back ache jointly, because of
This multidimensional anti-vibration performance being necessary to extend seat suspension.
Summary of the invention
It is an object of the invention to the deficiency for overcoming above-mentioned technology, i.e. limited by linear theory of vibration isolation, when
Front chair suspension is unsuitable for low-frequency vibration environment, and actual application seat suspension is only one-dimensional vertical direction
Vibration isolation suspension, is unsuitable for multi-dimensional vibration environment.The present invention provides a kind of based on nonlinear isolation principle non-
Road vehicle seat two-dimension non linearity vibration isolation suspension.The present invention has vertical direction, fore-and-aft direction vibration isolation is made
With, and all use nonlinear isolation principle, there is low frequency vibration isolation effect, it is adaptable to multiple highway car
, it is particularly suited for the off highway vehicle that this kind of porpoise of excavator is the biggest.
The present invention is made up of vertical vibration isolation part and vibration isolation part front and back, vertical vibration isolation part and front and back every
