Abstract
The invention relates to a double-swing linkage suspension support, which comprises support, muffle support mounted with steering joint upright axle, upper swing arm, lower swing arm, and connecting rod, wherein one end of upper and lower swing arms are hinged to the muffle support, while another end is hinged to the support to form four-bar device; one end of connecting rod is hinged to the upper and lower swing arms of four-bar device, while another end is hinged to the upper and lower swing arms; the hinge end of support of lower swing arm extends downwards in right angle; the connecting rod is hinged to the extending end of lower swing arm. The invention has the advantages that: it has little position parameter change, and stable operation. When it is used in the bridge suspension system with wide wheel distance and long vehicle, the support and suspension device will obtain better force function and low weight.
Description
Technical field
The suspension fork mechanism of the present invention and a kind of power actuated vehicle relates to a kind of double oscillating arms linked suspension that is used for the four-wheel motor vehicles rigid suspension specifically.
Background technology
Bridge suspension system before and after existing four-wheel powered industrial truck rigid suspension generally all adopts, one of them bridge and vehicle frame are rigidly connected, the middle part and the vehicle frame of another bridge be hinged, and vehicle frame has formed the form that three fulcrums support, and vehicle guarantees that four-wheel lands simultaneously during by uneven road surface.The major defect of this suspension is: in wheel bob process, the positional parameter of wheel changes greatly, and road-holding property is poor.When using in the left and right sides bridge suspension system in the front and back of wheelspan broad bridge suspension system or car body than length, the structure heaviness of bridge, intensity is low.
Summary of the invention
At above-mentioned situation, the object of the present invention is to provide a kind of double oscillating arms linked suspension that is used for four-wheel motor vehicles, adopt the wheel alignment parameter variation of this double oscillating arms linked suspension little, road-holding property is good.When using in the left and right sides bridge suspension system than length in the front and back of wheelspan broad bridge suspension system or car body, vehicle frame and suspension fork mechanism are stressed good, in light weight.
In order to achieve the above object, the present invention is achieved by the following technical solutions: a kind of double oscillating arms linked suspension, the bush support that comprises vehicle frame, installation steering swivel vertical shaft, also comprise top link, following swing arm and connecting rod, described top link, following swing arm one end are articulated in described bush support, the other end is articulated in vehicle frame and constitutes four-bar mechanism, and the top link of described connecting rod one end and this four-bar mechanism or following swing arm are hinged, and the other end and opposite side four-bar mechanism top link or following swing arm are hinged.
The described vehicle frame pin jointed end of swing arm down extends rectangular shape downwards, and described connecting rod is hinged with the right angle elongated end of following swing arm.
The pin jointed end reverse extending of described top link or following swing arm and vehicle frame, described connecting rod two ends are articulated in the reverse extending end of top link or following swing arm, are articulated in vehicle frame in the middle of the connecting rod.
Described four-bar mechanism is parallelogram four-bar mechanism or the not isometric four-bar mechanism of opposite side.
This double oscillating arms linked suspension can be arranged between the front and back wheel of car body, also can be arranged between the left and right wheels of car body, and promptly this double oscillating arms linked suspension both can be used as the left and right sides bridge suspension system of car body, also can be used as the front and back bridge suspension system of car body.
Major advantage of the present invention is: the positional parameter of wheel changes little, and road-holding property is good.When using in the left and right sides bridge suspension system than length in the front and back of wheelspan broad bridge suspension system or car body, vehicle frame and suspension fork mechanism are stressed good, in light weight.

Fig. 2 is the assembling scheme drawing of double oscillating arms linked suspension shown in Figure 1.
Fig. 3 is the structural representation of the another kind of double oscillating arms linked suspension of the present invention.
Among the figure
1. descend the reverse elongated end of 3. times swing arm jointed shafts of swing arm 2. wheels, 4. steering swivel vertical shaft 5. bush supports, 6. top link jointed shaft 7. top links, 8. vehicle frames 9. times swing arm right angles elongated end 10. connecting rods, 11. top links
The specific embodiment
Further narrate the present invention below in conjunction with left and right sides bridge suspension system (being that double oscillating arms linked suspension is arranged between the car body front and back wheel) embodiment and accompanying drawing thereof:
As shown in Figure 1 and Figure 2, double oscillating arms linked suspension of the present invention, the bush support 5 that comprises vehicle frame 8, installation steering swivel vertical shaft 4, also comprise top link 7, following swing arm 1 and connecting rod 10, described top link 7, following swing arm 1 one ends are articulated in described bush support 5, the other end is articulated in vehicle frame 8 and constitutes four-bar mechanism, and the top link 7 of described connecting rod 10 1 ends and this four-bar mechanism or following swing arm 1 are hinged, and the top link of the other end and opposite side four-bar mechanism or following swing arm are hinged.
In Fig. 2, the described vehicle frame pin jointed end of swing arm 1 down extends rectangular shape downwards, and described connecting rod 10 is hinged with the right angle elongated end 9 of following swing arm.
In Fig. 3, the vehicle frame pin jointed end of described top link 7 (or swing arm down) is to reverse extending, and described connecting rod 10 two ends are articulated in top link reverse extending end 11 (or following swing arm reverse extending end), are articulated in vehicle frame 8 in the middle of the connecting rod.
Described four-bar mechanism can be parallelogram four-bar mechanism or the not isometric four-bar mechanism of opposite side.
This double oscillating arms linked suspension can be arranged between the front and back wheel of car body, also can be arranged between the left and right wheels of car body.
The principle of work of the present invention's suspension shown in Figure 2 is as follows:
In double oscillating arms linked suspension, swing arm 1 under the square, top link 7, bush support 5 and vehicle frame 8 are formed four-bar mechanism, when Uneven road, if wheel 2 upward movements in the end suspension, wheel 2 drives bush support 5 upward movements, bush support 5 rotates around the vehicle frame jointed shaft by swing arm 1 under the following swing arm hinging pin shaft 3 drive squares, the right angle elongated end 9 of swing arm 1 under the square is by rod hinge connection axle drivening rod 10 parallel motions, connecting rod 10 rotates by swing arm 1 under the square in the rod hinge connection axle drive other end suspension, the wheel 2 of this end is moved downward, because the symmetry of two suspension rod members, the distance of jumping on the wheel of two ends and jumping is down equated, thereby four wheels land simultaneously when guaranteeing to travel on uneven road surface, to guarantee vehicle run stability and tractive property preferably.Form four-bar mechanism with swing arm under the square 1, top link 7, bush support 5 and vehicle frame 8, the variation and the motion characteristics of positional parameter when guaranteeing the wheel bob.
The principle of work of suspension shown in Figure 3 and suspension principle of work shown in Figure 2 are basic identical, and different just does the swing of lever drives four-bar mechanism with connecting rod 10, replace connecting rod 10 and make stayed pole and drive four-bar mechanism and swing.
Describe the present invention with way of example above, but the invention is not restricted to above-mentioned specific embodiment, all protection domains that any improvement that the present invention did or modification are all belonged to claim of the present invention.
