Abstract
The utility model proposes a kind of trailer/semi-mounted Vehicle Pneumatic Suspension System device, comprise flat spring bracket, leaf spring, leaf spring interlude is fixed on axletree by anchor fitting, 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 ball pivot with one end of hydro-pneumatic spring cylinder by lower bracket, and the other end of hydro-pneumatic spring cylinder is connected on upper bracket by ball pivot again, and upper bracket is fixed on vehicle frame.The utility model cushions by the compressibility of hydro-pneumatic spring cylinder, damping hole carries out vibration damping to the control of oil flow, instead of steel laminated spring or air bellow, apply to, on trailer or semi-mounted carrier, realize the raising in Vehicle Driving Cycle ride comfort, vibration damping and life-span.
Description
Technical field
The utility model relates to the suspension system that trailer and semi-mounted carrier are used, especially a kind of trailer/superimposed trailer hydro pneumatic suspension device.
Background technology
At present, the suspension system that trailer and semi-mounted carrier are used is conventional steel spring traditional suspension, because the rigidity of elastic element is mostly linear, and its rigidity is remained unchanged substantially, even adopt the measures such as Varying-thickness, major-minor steel plate to performance to improve effect not remarkable yet, and the energy storage of air suspension You You unit is compared with deficiencies such as little, scantling of structure large, complex structure, parts kind are many, roll angular rigidity is low.
Summary of the invention
The ride comfort travelling in order to improve trailer or semi-mounted carrier, improves effectiveness in vibration suppression, reduces dynamic factor, the utility model proposes a kind of trailer/semi-mounted Vehicle Pneumatic Suspension System device.
For this reason, the technical solution of the utility model is as follows: a kind of trailer/semi-mounted Vehicle Pneumatic Suspension System device, comprise flat spring bracket, leaf spring, it is characterized in that: leaf spring interlude is fixed on axletree by anchor fitting, one end bag ear of leaf spring is hinged on flat spring bracket, and flat spring bracket is fixed on vehicle frame, and the other end of leaf spring is connected by ball pivot with one end of hydro-pneumatic spring cylinder by lower bracket, the other end of hydro-pneumatic spring cylinder is connected on upper bracket by ball pivot again, and upper bracket is fixed on vehicle frame.
Beneficial effect: the utility model cushions by the compressibility of hydro-pneumatic spring cylinder, damping hole carries out vibration damping to the control of oil flow, instead of steel laminated spring or air bellow, apply to, on trailer or semi-mounted carrier, realize the raising in Vehicle Driving Cycle ride comfort, vibration damping and life-span.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the lateral plan of the utility model installing condition on six-wheel vehicle.
Shown in figure: 1, upper bracket 2, hydro-pneumatic spring cylinder 3, lower bracket 4, axletree 5, leaf spring 6, flat spring bracket 7, vehicle frame, 8, clevis bolt, 9, pressing plate, the 10, first axletree, the 11, second axletree, 12, the 3rd axletree.
The specific embodiment
(a kind of trailer/superimposed trailer) hydro pneumatic suspension device as shown in Figure 1, comprise upper bracket 1, hydro-pneumatic spring cylinder 2, lower bracket 3, leaf spring 5(singlely also can be with auxiliary spring as shown in the figure), flat spring bracket 6, leaf spring 5 interludes have two by clevis bolt 8 and pressing plate 9(pressing plate 9, arrange up and down, clevis bolt 8 is from the lower pressing plate 9 that passes, pass through nut locking) be fixed on axletree 4, one end bag ear of leaf spring 5 is hinged on flat spring bracket 6, flat spring bracket is fixed on vehicle frame 7, the other end of leaf spring 5 is connected by ball pivot with one end of hydro-pneumatic spring cylinder 2 by lower bracket 3, the other end of hydro-pneumatic spring cylinder 2 is connected on upper bracket 1 by ball pivot again, 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 and vehicle frame.
As shown in Figure 1, clevis bolt 8 and pressing plate 9 form anchor fitting, and the utility model is not limited to this, anchor fitting
Also can be other version, as long as anchor fitting can be fixed on axletree just passable leaf spring 5 interludes.
Characteristic of the present utility model: stiffness characteristics is nonlinear, when the change in displacement less (from static balance) of suspension, its rigidity value is less, and changes littlely, has had good ride comfort when vehicle is travelled on road surface preferably; When suspension displacement changes greatly, its rigidity also increases sharply, and makes vehicle when poor road traveling, have good impact resistance; That is to say and adopt this vehicle of the present utility model when the very large road traveling of above-mentioned two kinds of difference, can keep higher moving velocity.Damping force characteristics of the present utility model is also nonlinear, and when hydro-pneumatic spring is during in compressive state, the dumping force of spring cylinder is lower, and its pooling feature has mainly been changed by air compressing; When hydro-pneumatic spring is during in reset condition, the closed check valve in hydro-pneumatic spring cylinder, fluid can only flow through by damping hole, makes like this oil flow strengthen, and hydro-pneumatic spring cylinder produces larger dumping force, suppressed to restore motion, and damped vibration rapidly.This device object is exactly to utilize the change rigidity of hydro-pneumatic spring cylinder and become damping force characteristics to reach good buffering and effectiveness in vibration suppression.
As shown in Figure 2, on six-wheel vehicle, there are the first axletree 10, the second axletree 11, the 3rd axletree 12, the first axletrees 10, the second axletree 11 and the 3rd axletree 12 places that the utility model (a kind of trailer/superimposed trailer) hydro pneumatic suspension device is all installed.
