Operation principle of the present utility model：The plate spring assembly is manufactured into arch girder construction from steel spring plate, and by list
Piece or multi-disc leaf spring is to plus lap and links together, the two ends of plate spring assembly are connected by swing arm bulb with knuckle assembly lower end
Connect.This kind of bulb type connected mode compared with grasswort formula connected mode, can be obviously reduced traveling in noise and wheel can be realized
Freely turn to, leaf spring plays the connection function of front axle by the connection with knuckle assembly, the characteristics of due to material itself, also
The cushioning effect of spring is played, leaf spring is pressed on the gum cover structure below longeron so that plate spring assembly has had excellent longitudinal direction just
Degree, instead of lower yoke.In vehicle travel process, when the road surface of wheels travel is uneven, horizontal plate spring assembly, upper fork
Arm assembly will be swung up and down, and certain guide effect has been moved to wheel, meanwhile, preceding shock absorber constantly compresses, upholds, and rises
To damping effect, when steering gear rack acts on drag link, the left and right turn of wheel is can be achieved with, for further loss of weight, plate
Spring also can be using fiberglass reinforced plastics (GFRP) manufacture of required specification.
Due to using transverse leaf spring scheme, horizontal leaf spring instead of left and right lower swing arm to the utility model, and have transverse direction concurrently
The effect of stabiliser bar, eliminates brace structure, and serves the effect of guiding, and a parts have multiple function, make knot
Structure is simpler, greatly reduces the weight of front overhang, it is preferred that when leaf spring is also adopted by the glass fiber reinforcement modeling of required specification
When material (GFRP) is manufactured, further loss of weight is realized.
The utility model safeguards simple due to causing its simple structure using above-mentioned technical scheme, lightweight, is manufactured into
This is low, and safe and reliable, comfortableness is good, and the utility model especially reduces size of the front overhang structure in short transverse in addition, makes whole
Car exterior design has a bigger performance space, and vehicle frame is appropriate increase by meet the installation requirement of front overhang, vehicle body can be designed
It is Non-carrying type structure, significantly reduces the weight of vehicle, compared to traditional leaf spring grasswort connected mode, the utility model is used
Bulb connected mode, especially reduces the noise of leaf spring in traveling and can realize freely turning to for wheel, when leaf spring is also adopted by institute
When needing the fiberglass reinforced plastics (GFRP) of specification to manufacture, further loss of weight is realized, and coordinate making for preceding shock absorber
With so that effectiveness in vibration suppression is remarkably reinforced, it is adaptable to cyclecar and small-sized electric car.

Specific embodiment
With reference to Fig. 1-Fig. 6, the utility model provides a kind of transversal leaf spring type independent suspension structure, including knuckle assembly 1/
7th, upper yoke assembly 3/5, steering assembly 4, tie rod assembly 2/6, bracket of shock absorber 8/10, transverse leaf spring assembly 9.
The transverse leaf spring assembly is manufactured into arch girder construction from steel spring plate, and aligns weight by monolithic or multi-disc leaf spring
Fold and link together, the two ends of plate spring assembly are connected by swing arm bulb with knuckle assembly lower end, leaf spring is used with bulb
Rivet or be spirally connected, it is preferred that for further loss of weight, leaf spring also can be using the fiberglass reinforced plastics (GFRP) of required specification
Manufacture.The two ends of leaf spring are connected by swing arm bulb with knuckle assembly lower end, if multi-disc plate spring structure, also comprising a groove
Type sheet metal component, it is connected with subframe, and leaf spring is coated in groove, prevents leaf spring from producing front-back staggered, leaf spring is pressed on vertical
Gum cover structure below beam causes that plate spring assembly has more excellent longitudinal rigidity, instead of lower yoke.
There is good rigidity reply from the positive shock of automobile using the leaf spring of said structure form and reed is kept
Front-back staggered is less prone to after impact.
Due to using transverse leaf spring scheme, horizontal plate spring assembly instead of left and right lower swing arm to the utility model, and have concurrently
The effect of QS, eliminates brace structure, and serves the effect of guiding, and a parts have multiple function,
Make structure simpler, greatly reduce the weight of front overhang.
In addition, being improved as a kind of, the two ends of leaf spring are connected by swing arm bulb with knuckle assembly lower end, this kind of structure
The advantage of form is：The gap of leaf spring two ends junction is reduced, when driving, compared to traditional leaf spring connection side
Formula, the utility model especially reduces the noise of leaf spring in traveling and can realize freely turning to for wheel.
Bracket of shock absorber upper end is connected by front overhang upper end mounting bracket with vehicle frame front end, it is preferred that current shock absorber
Assembly lower end is packed in when in plate spring assembly, also comprising shock absorber lower end mounting bracket, when bracket of shock absorber lower end is packed in
When in knuckle assembly, not comprising shock absorber lower end mounting bracket, bracket of shock absorber is cylinder type damper, symmetrical cloth
Put.Due to arranging preceding shock absorber so that effectiveness in vibration suppression is remarkably reinforced.
Mount point of the steering assembly body comprising casting, and be connected on fore sub frame assembly by this mount point.With
Not cast mounting means is compared, and it is not smart that this kind of mounting means eliminates the steering caused by the deformation of rubber parts at mount point
Really, improve control stability.
The upper yoke assembly main body is formed by steel plate punched or casting, is connected by ball head structure with knuckle assembly upper end
Connect, front overhang upper end mounting bracket is shared using gum cover structure when being connected with vehicle frame and with bracket of shock absorber, can bear certain
