Abstract
The present invention proposes a kind of trailer/semi-mounted Vehicle Pneumatic Suspension System device, including flat spring bracket, leaf spring, leaf spring interlude is fixed on axle by fixing device, one end bag ear of leaf spring is hinged on flat spring bracket, flat spring bracket is fixed on vehicle frame, the other end of leaf spring is connected by lower carriage with one end of hydro-pneumatic spring cylinder by flexural pivot, and the other end of hydro-pneumatic spring cylinder is connected on upper bracket by flexural pivot again, and upper bracket is fixed on vehicle frame.For the present invention by the compressibility of hydro-pneumatic spring cylinder into row buffering, control of the damping hole to oil flow carries out vibration damping, substitutes leaf spring or air spring, applies on trailer or semi-mounted carrier, realize vehicle ride performance, damping and the service life raising.
Description
Technical field
The present invention relates to the suspension system of trailer and semi-mounted carrier, especially a kind of trailer/semitrailer oil gas hanging
Rack device.
Background technology
At present, the suspension system of trailer and semi-mounted carrier is common leaf spring traditional suspension, because of elastic member
The rigidity of part is mostly linear, and is held essentially constant its rigidity, even if using measures such as Varying-thickness, major-minor steel plates to property
Can improvement also not significantly, and air suspension have unit energy storage compared with it is small, structure size is big, complicated, parts kind
The deficiencies such as class is more, roll angular rigidity is low.
The content of the invention
In order to improve the ride comfort of trailer or semi-mounted carrier traveling, effectiveness in vibration suppression is improved, reduces dynamic load factor, this hair
It is bright to propose a kind of trailer/semi-mounted Vehicle Pneumatic Suspension System device.
For this reason, technical scheme is as follows：A kind of trailer/semi-mounted Vehicle Pneumatic Suspension System device, including flat spring bracket,
Leaf spring, it is characterised in that：Leaf spring interlude is fixed on axle by fixing device, and one end bag ear of leaf spring is hinged on leaf spring branch
On frame, flat spring bracket is fixed on vehicle frame, and the other end of leaf spring is connected by one end of lower carriage and hydro-pneumatic spring cylinder by flexural pivot
Connect, the other end of hydro-pneumatic spring cylinder is connected on upper bracket by flexural pivot again, and upper bracket is fixed on vehicle frame.
Beneficial effect：The present invention is by the compressibility of hydro-pneumatic spring cylinder into row buffering, control of the damping hole to oil flow
System carries out vibration damping, substitutes leaf spring or air spring, applies on trailer or semi-mounted carrier, realizes vehicle traveling smooth-going
Property, damping and the service life raising.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Fig. 2 is the side view of present invention installment state on six-wheel vehicle.
Shown in figure：1st, upper bracket 2, hydro-pneumatic spring cylinder 3, lower carriage 4, axle 5, leaf spring 6, flat spring bracket 7, car
Frame, 8, U bolt, 9, pressing plate, the 10, first axle, the 11, second axle, the 12, the 3rd axle.
Embodiment
As shown in Figure 1（A kind of trailer/semitrailer）Hydro pneumatic suspension device, including upper bracket 1, hydro-pneumatic spring cylinder 2, lower branch
Frame 3, leaf spring 5（Can be it is single can also as shown in the figure band auxiliary spring）, flat spring bracket 6,5 interlude of leaf spring by U bolt 8 and
Pressing plate 9（Pressing plate 9 has two, and arrangement, U bolt 8 pass through nut check from below through pressing plate 9 up and down）It is fixed on axle 4,
One end bag ear of leaf spring 5 is hinged on flat spring bracket 6, and flat spring bracket is fixed on vehicle frame 7, and the other end of leaf spring 5 passes through lower branch
Frame 3 is connected with one end of hydro-pneumatic spring cylinder 2 by flexural pivot, and the other end of hydro-pneumatic spring cylinder 2 is connected to upper bracket 1 by flexural pivot again
On, upper bracket 1 is fixed on vehicle frame 7.
As shown in Figure 1, flat spring bracket 6 and upper bracket 1 are fixed by welding or bolt connecting mode with vehicle frame.
As shown in Figure 1, U bolt 8 and pressing plate 9 form fixing device, not limited to this, fixing device of the invention
Can also be other structure type, as long as fixing device can be fixed on 5 interlude of leaf spring on axle.
The characteristic of the present invention：Stiffness characteristics are nonlinear, when the change in displacement of suspension is smaller（Since static balance）When,
Its rigidity value is smaller, and change is smaller, vehicle is provided with preferable ride comfort when driving on preferable road surface；When suspension position
When shifting changes greatly, its rigidity also increases sharply, and vehicle is had preferable impact resistance in poor road traveling；Also
It is to say that higher traveling speed can be kept in the very big road traveling of above two difference using the vehicle of the invention
Degree.The damping characteristic of the present invention is also nonlinear, and when hydro-pneumatic spring is in compressive state, the damping force of spring cylinder compares
Low, its pooling feature is mainly completed by air compression variation；When hydro-pneumatic spring is in reset condition, in hydro-pneumatic spring cylinder
Closed check valve, fluid can only be flowed through by damping hole, so increase oil flow, and hydro-pneumatic spring cylinder produces larger damping
Power, it is suppressed that restoring movement, and rapidly decay vibration.The purpose of present apparatus is exactly the variation rigidity and variable resistance using hydro-pneumatic spring cylinder
Damping characteristics reach good buffering and effectiveness in vibration suppression.
As shown in Fig. 2, have the first axle 10, the second axle 11, the 3rd axle 12 on six-wheel vehicle, the first axle 10,
A present invention is fitted with two axles 11 and the 3rd axle 12（A kind of trailer/semitrailer）Hydro pneumatic suspension device.
Claims (3)
