The specific embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
Embodiment
Shown in Fig. 1～9, Fig. 1 is structural representation of the present utility model; Fig. 2 is part sectional view of the present utility model; Fig. 3 is the assembled state scheme drawing of leaf spring and rubber locating piece; Fig. 4 is the structural representation of leaf spring; Fig. 5 is the structural representation of rubber locating piece; Fig. 6 is the right elevation of rubber locating piece; Fig. 7 is the structural representation that crossbeam is installed; Fig. 8 is the block diagram that crossbeam is installed; Fig. 9 is the front view that crossbeam is installed.
A kind of automobile double cross arm independent suspension mechanism comprises leaf spring 1, rubber locating piece 2 and crossbeam 3 is installed; In the prior art, also comprise crossbeam 3, swing arm 6 down, top link 7, shock absorber 8, vehicle frame (or vehicle body) 9 are installed.Leaf spring 1 is connected with rubber locating piece 2 by carrying the mode that compresses in advance, and rubber locating piece 2 is connected with installation crossbeam 3 bolts, and leaf spring 1 and rubber locating piece 2 reduce respectively gradually towards the thickness of both sides wheel 4 directions.
The cross-sectional plane that crossbeam 3 is installed is inverted U, avoids installing crossbeam 3 front and back and slides, and can be used with other parts preferably.
Install on the crossbeam 3 mounting hole 31 is set, mounting hole 31 be strip hole, and the long limit of strip hole is perpendicular to both sides wheel 4, can be according to different automobile types, position the applicability of raising product at the diverse location of strip hole.
In alternative of the present utility model, the installation crossbeam of rubber locating piece 2 and strap bolt 3 links together by sulfuration process.
In the timing of vehicle initial loading, can be according to the carrying size of vehicle, corresponding adjustment rubber locating piece 2 is in the position of installing on the crossbeam 3.Crossbeam 3 is installed can be connected with vehicle frame (or vehicle body) 9 welding or bolt.The medial extremity of the medial extremity of following swing arm 6 and top link 7 and shock absorber 8 upper ends and vehicle frame (or vehicle body) 9 are hinged.Shock absorber 8 lower ends are connected with following swing arm 6 bolts.The segmentum laterale of following swing arm 6 and Top Crossbeam 7 is connected with wheel 4 and member thereof.The mid-depth of non-metal leaf spring 2 is 25mm, the thickness of two side ends be 10mm to 20mm, non-metal leaf spring 2 centers are along dual-side direction thickness attenuate progressively.
When running car, to jump on the wheel, the non-metal leaf spring is jumped on 1 two ends, and progressively contacts with thickening degree rubber locating piece 2 along the wheel edge direction, thereby arm of force L is reduced, and suspension system rigidity is corresponding increase then.Thereby improve road-holding property and the ride comfort of automobile.
The utility model automobile double cross arm independent suspension system is owing to adopt non-metal leaf spring 1 horizontal structure, and non-metal leaf spring 1 adopts the design of thickening degree simultaneously, can effectively lower the weight of suspension system elastic element, reduces the suspension system number of parts.The use of non-metal leaf spring 1 can also avoid metallic elastic component to vibrate the noise that sends when vehicle travels.The rubber position fixing system of employing thickening degree can change the stressed arm of force size of suspension in the automobile use, to reach the rigidity of dynamic change suspension system, improves road holding.
