Abstract

The utility model relates to a suspension device for automobile, the especially linkage that the car held stationary moved, the device is including installing the torsion bar spring that hangs around the car homonymy, and this torsion bar spring front portion links to each other with the car front wheel, and well torsion arm passes through hinge structure and is connected with jackshaft trailing arm one end, and the jackshaft trailing arm other end is connected to the car rear wheel. The utility model discloses offset partly stress at the interact of automobilism in -process accessible torsion bar spring and jackshaft trailing arm, make the automobile body can not produce too big angular oscillation to reduce the fluctuation of automobilism, improve the comfort level of taking the people.

Description

Automobile suspension arrangement

Technical field

The utility model relates to a kind of automobile suspension arrangement, and particularly automobile front-and-back damping uses the automobile suspension arrangement of torsion bar spring.

Background technology

At present, market is got on the car in the suspended shock damper of held stationary operation, many employings torsion bar spring, and even between damping elastic element before and after automobile be independently, mutually without any contact, when automobile runs into impact, suffered application force can strengthen, the fluctuation fallen after rising before vehicle body can produce, maintains automobile balance operation and has certain limitation.Patent documentation " automobile suspension arrangement " (patent No.: CN201020598879) discloses and a kind ofly to be connected by damping spring in automobile front-and-back damping, damping spring before and after automobile is made to set up certain response relation, to reduce the automobile suspension arrangement that people's comfort level is taken in automobile vibrations in the process of moving and raising, but the technical scheme complex structure described by this patent documentation, have impact on it in real-life application.

Utility model content

For prior art Problems existing and deficiency, the utility model provides a kind of structure simple, automobile suspension arrangement easily manufactured, with low cost.

The utility model realizes in the following way:

A kind of automobile suspension arrangement, comprise torsion bar spring, jackshaft, jackshaft trailing arm and hinge arrangement, torsion bar spring front portion is connected with front-wheel, torsion bar spring rear portion is fixedly connected with bottom of car crossbeam, jackshaft is positioned in the middle part of jackshaft trailing arm, jackshaft trailing arm one end is connected with hinge arrangement, and the other end is connected with trailing wheel;

Preferably, in the middle part of described torsion bar spring, torque arm in torsion bar spring is set;

Preferably, described torsion bar spring end arranges torsion bar spring regulating arm;

Preferably, described hinge arrangement respectively with torsion bar spring, jackshaft trailing arm chain connection;

Preferably, described jackshaft trailing arm is connected by steel spring with trailing wheel.

The beneficial effects of the utility model:

1, reasonable in design, structure is simple, and the suspension be connected with automobile front and back wheel shares a torsion bar spring, cheap for manufacturing cost;

2, damping effect is obvious, when automobile is impacted, due to torsion bar effect, effectively can reduce the angular oscillation that vehicle body is subject to, vehicle body is operated steadily.

When front-wheel is pitched by uneven road surface, torsion bar spring regulating arm is attachment point, under the drive of front-wheel, do reciprocal torsion; When front-wheel is subject to an impulsive force upwards, front-wheel drives torsion bar spring to do counterclockwise movement (body forward structure moves up simultaneously), in torsion bar spring, torque arm rotates counterclockwise (reduce by half rotation) simultaneously and drives hinge jackshaft trailing arm to be rotated clockwise press down trailing wheel, jackshaft is moved up on (for ground), and namely body tail moves up; When trailing wheel is subject to an impulsive force upwards, trailing wheel drives jackshaft trailing arm to rotate counterclockwise certain angle, pulls hinge, makes torsion bar spring rotate clockwise certain angle, and torsion bar spring at front end drives front-wheel downward pressure that body forward structure is moved up.Enforcement of the present utility model can effectively ensure that automobile balance runs, and reduces the angular oscillation that auto body is subject to, and improves the comfort level taking people.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation.

In figure: torque arm, 4 torsion bar spring rear portions, 5 torsion bar spring regulating arms, 6 torsion bar springs, 7 trailing wheels, 8 jackshafts, 9 jackshaft trailing arms, 10 hinge arrangements in 1 front-wheel, 2 torsion bar springs front portions, 3 torsion bar springs.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described, makes the technical solution of the utility model and effect easy to understand.

The utility model is the suspension gear that the suspension of front and back wheel homonymy shares a torsion bar spring 6, the suspension of this device can improve vehicle at the ride comfort of road traveling that jolts, reduce at the angular oscillation on road surface that jolts, when front-wheel 1 by during uneven road surface upward movement with torsion bar spring regulating arm 5 for attachment point, front-wheel 1 drives the other end of torsion bar spring 6 to rotate up, vehicle body now above body forward structure front-wheel 1 also rises certain height simultaneously, the middle torque arm 3 of torsion bar spring is also rotate up certain angle and pull hinge arrangement 10 simultaneously, make jackshaft trailing arm 9 with jackshaft 8 for the certain angle of clickwise is done in the center of circle, cause the height that above trailing wheel 7, vehicle body is simultaneously upwards certain, no matter that front-wheel 1 or trailing wheel 7 run into uneven road surface when pitching, vibration before and after vehicle body is all overall synchronous up-down vibration.

If run into uneven road surface front and back wheel vibrate simultaneously and direction of vibration is contrary time, the impulsive force suffered by front and back wheel can be offset when synchronous motion is in the same way done in jackshaft trailing arm 9 one end that the middle torque arm 3 of torsion bar spring is connected with hinge arrangement 10.When front and back wheel is identical by uneven road surface direction of vibration, with torsion bar spring regulating arm 5 for attachment point, in torsion bar spring, torque arm 3 is done and trailing wheel 7 reversing sense up-and-down movement, the up-and-down movement that the sense of motion of front-wheel 1 is simultaneously also contrary with torque arm 3 in torsion bar spring, cause torsion bar spring anterior 2 and torsion bar spring rear portion 4 torsional deflection in various degree, reach vehicle body frames and front and back wheel does relative motion, play vibration reduction and cushioning effect.

More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
