Abstract
The invention provides an oil-gas suspension device for a trailer/semitrailer. The oil-gas suspension device for the trailer/semitrailer comprises a plate spring support and a plate spring, wherein a middle segment of the plate spring is fixed on a car shaft through a fixed device, a packing ear which is arranged on one end of the plate spring is hinged on the plate spring support, the plate spring support is fixed on a car frame, the other end of the plate spring is connected with one end of an oil-gas spring cylinder through a lower support and a spherical hinge, the other end of the oil-gas spring cylinder is connected onto an upper support through a spherical hinge, and the upper support is fixed on the car frame. The oil-gas suspension device for the trailer/semitrailer buffers through compressibility of the oil-gas spring cylinder, damps by controlling flow speed of oil liquid through a damping hole, replaces a steel plate spring or an air spring, and is applied on the trailer or the semitrailer, thereby achieving riding comfort and damping of cars, and prolonging life.
Description
Technical field
The present invention relates to the suspension system of trailer and semi-mounted carrier, especially a kind of trailer/superimposed trailer hydro pneumatic suspension device.
Background technology
At present, the suspension system of trailer and semi-mounted carrier is conventional steel spring traditional suspension, rigidity because of elastic element is mostly linear, and its rigidity is remained unchanged substantially, even if the measure such as Varying-thickness, major-minor steel plate of employing is also remarkable to the improvement effect of performance, and air suspension has unit energy storage 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
In order to improve the ride comfort of trailer or semi-mounted carrier traveling, improving effectiveness in vibration suppression, reducing dynamic factor, the present invention proposes a kind of trailer/semi-mounted Vehicle Pneumatic Suspension System device.
For this reason, technical scheme of the present invention 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 by lower bracket one end with hydro-pneumatic spring cylinder, 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 present invention is cushioned by the compressibility of hydro-pneumatic spring cylinder, damping hole carries out vibration damping to the control of oil flow, substitute steel spring or air bellow, apply on trailer or semi-mounted carrier, realize the raising in vehicle riding comfort, damping and life-span.

Fig. 2 is the lateral plan of the present invention's 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.
detailed description of the invention
(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 interlude has two by clevis bolt 8 and pressing plate 9(pressing plate 9, arrange up and down, clevis bolt 8 passes pressing plate 9 from lower, 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 by lower bracket 3 one end with hydro-pneumatic spring cylinder 2, 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 present invention 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 interlude.
Characteristic of the present invention: stiffness characteristics is nonlinear, when the change in displacement of suspension less (from static balance), its rigidity value is less, and change is less, is provided with good ride comfort when vehicle is travelled on good road surface; When suspension displacement changes greatly, its rigidity also increases sharply, and makes vehicle have good impact resistance when poor road traveling; That is this vehicle of the present invention is adopted when the road traveling that above-mentioned two kinds of difference are very large, can to keep higher moving velocity.Damping force characteristics of the present invention is also nonlinear, and when hydro-pneumatic spring is in compressive state, the dumping force of spring cylinder is lower, and its pooling feature has come primarily of air compressing change; When hydro-pneumatic spring is in reset condition, the closed check valve in hydro-pneumatic spring cylinder, fluid can only be flow through by damping hole, makes oil flow strengthen like this, and hydro-pneumatic spring cylinder produces larger dumping force, inhibits restoring movement, and damped vibration rapidly.This device object is exactly utilize the variation rigidity of hydro-pneumatic spring cylinder and mutative damp characteristic to reach good buffering and effectiveness in vibration suppression.
As shown in Figure 2, six-wheel vehicle there are the first axletree 10, second axletree 11, the 3rd axletree 12, first axletree 10, second axletree 11 and the 3rd axletree 12 place that a present invention (a kind of trailer/superimposed trailer) hydro pneumatic suspension device is all installed.
