Abstract
The utility model discloses a front suspension device of an electric automobile. The front suspension device of the electric automobile comprises a shock absorber between a vehicle frame and a steering knuckle, a spiral spring which is arranged at the outer side of the shock absorber and a lower swing arm which is connected between the vehicle frame and the steering knuckle, wherein the lower swing arm is arranged below the shock absorber. The front suspension device of the electric automobile is characterized in that the intermediate diameter of the spiral spring is 132.4 mm, the wire diameter of the spiral spring is 11.7 mm, and the number of active coils is 3.5. By means of the rear suspension device of the electric automobile, the stiffness of the spiral springs is higher, and driving comfort of the electric automobile is guaranteed in the premise that the whole vehicle posture is guaranteed.
Description
Technical field
The utility model relates to a kind of electronlmobil, is specifically related to a kind of front suspension apparatus of electronlmobil.
Background technology
Suspension is the driving force connecting device between vehicle frame and axletree, its effect be the road surface act on vertical reaction on wheel, vertically the moment that causes of counter-force and lateral reaction and these counter-forces is delivered on vehicle frame, to guarantee normally travelling of automobile.
Automotive suspension can be divided into two large classes: dependent suspension and independent suspension.The constructional feature of dependent suspension is that the wheel of both sides is connected by a rigid axle, wheel is connected with vehicle frame by resilient suspension together with vehicle bridge, when single wheel is beated because road is uneven, must cause that the opposite side wheel swings in the automobile Transverse plane.The constructional feature of independent suspension is that vehicle bridge is made disconnection, and the resilient suspension that passes through that every single wheel can be independent is connected with vehicle frame, and the both sides wheel can be beated separately, is independent of each other.
McPherson strut is one of independent front suspension of car the most widely of using of the world today.McPherson strut is made of coil spring, shock absorber and lower swing arm usually.Upper end and the vehicle frame of shock absorber are connected through the hinge, the lower end of shock absorber is connected with steering swivel, coil spring is sheathed on outside shock absorber, the inner and the vehicle frame of lower swing arm are connected through the hinge, the outer end of lower swing arm and steering swivel connect, shock absorber play the guiding role, and in the time of can avoiding coil spring stressed, to the phenomenon of front, rear, left and right skew, lower swing arm can bear from the lateral impact of wheel and longitudinal impact load.McPherson strut is simple in structure, lightweight, fast response time.
Yet due to the structure of electronlmobil self and the battery difference of selecting, existing McPherson strut can't be driven traveling comfort in order to guarantee taking advantage of of electronlmobil directly as the front suspension of electronlmobil, and the structure of front suspension awaits to improve.
Summary of the invention
The deficiency that the utility model exists in order to overcome prior art provides the more reasonably front suspension apparatus of electronlmobil of a kind of structure.
The utility model is achieved through the following technical solutions: a kind of front suspension apparatus of electronlmobil, comprise the shock absorber that is connected between vehicle frame and steering swivel, be sheathed on the coil spring in the shock absorber outside and be connected to vehicle frame and steering swivel between lower swing arm, described lower swing arm is positioned at the below of described shock absorber, and described helical spring central diameter is that 132.4mm, wire diameter are that 11.7mm, number of active coils are 3.5 circles.
The beneficial effects of the utility model are: in the utility model, helical spring rigidity is stronger, under the prerequisite that guarantees the car load attitude, has guaranteed that taking advantage of of electronlmobil drive traveling comfort.
Description of drawings
Fig. 1 is the structural representation of left one side of something of front suspension apparatus of the present utility model.
In the drawings: the 1-shock absorber; The 2-coil spring; The 3-lower swing arm.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of front suspension apparatus of electronlmobil, comprise the shock absorber 1 that is connected between vehicle frame and steering swivel, be sheathed on the coil spring 2 in shock absorber 1 outside and be connected to vehicle frame and steering swivel between lower swing arm 3, lower swing arm 3 is positioned at the below of shock absorber 1, and the central diameter of coil spring 2 is that 132.4mm, wire diameter are that 11.7mm, number of active coils are 3.5 circles.
The structure of left one side of something of front suspension apparatus is identical with the structure of right one side of something, and both have consisted of the front suspension apparatus of whole electronlmobil.
Should be noted that at last; above content is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement does not all break away from essence and the scope of technical solutions of the utility model.
