Description
Technical Field
The utility model belongs to the technical field of the vehicle spare part, concretely relates to hang swing arm and suspension.
Background
The suspension is a general name of all force transmission connecting devices between an axle and the axle or wheels of a vehicle, and most vehicle deflection stabilizing systems comprise elastic elements, shock absorbers, guide mechanisms and the like, wherein the three parts respectively play roles in buffering, damping and force transmission. The suspension system can be divided into a non-independent suspension system and an independent suspension system according to different structures: the non-independent suspension system is characterized in that a rod piece is directly and rigidly connected to wheels on two sides, and the impact and vibration of the wheel on one side inevitably affect the wheel on the other side, so that the steering stability and the comfort are lower, and simultaneously, the stability of a vehicle body is easily affected due to the mutual influence of the wheels on the left side and the right side, and the vehicle body is easy to roll over when steering. The independent suspension system is characterized in that the wheels on the two sides of the vehicle are independently connected with the vehicle body, so that the wheels on one side can absorb impact force through the elastic elements after being impacted and vibrated, the impact force cannot affect the wheels on the other side, and the riding comfort, the stability and the operation stability of the vehicle are improved.
The existing functional vehicles such as a scooter, a beach vehicle and a kart have higher requirements on driving experience, most of the functional vehicles use an independent suspension system, and the MacPherson type independent suspension is widely used due to the fact that the MacPherson type independent suspension has the advantages of simple structure, small occupied space, fast response and low manufacturing cost, however, the MacPherson type independent suspension has the advantages of small transverse rigidity, poor stability and large turning heeling, and the defects reduce the safety of steering operation of the vehicle in the high-speed driving process to a certain extent. In general, when the axle deflects by about 5 degrees, the wheel lift-off phenomenon occurs, and a large potential safety hazard exists.
In the prior art, when the axle deflects at a large angle, the deflection states of wheels at two sides can be respectively controlled through the double-wishbone type suspension, and the wheels at the outer side are fixed on the ground as far as possible. The technology that the deflection of the wheels on two sides is connected together through a specific structure on an independent suspension and the deflection state of the wheel on one side is conducted to the wheel on the other side through the specific structure is not available.
SUMMERY OF THE UTILITY MODEL

the utility model provides a hang swing arm, includes fixed axle and swing arm body, the swing arm body is connected with the fixed axle is articulated, the swing arm body includes limit structure and sways the structure, limit structure and swaying the structure and rotate around the fixed axle, limit structure can inject the swing arm body around the rotation angle of fixed axle, it is equipped with first shock attenuation connection structure and second shock attenuation connection structure to sway the structure both sides.
Optionally, the swing arm body rotates around the fixed shaft and deviates from the two sides of the vertical direction by a rotation angle of less than or equal to 30 degrees. If the deflection is too large, the gravity center offset angle of the vehicle is too large, and the stability of the vehicle body is influenced. Such as some stunt vehicles, may employ larger yaw angles.
Optionally, the swing arm body rotates around the fixed shaft and deviates from the two sides of the vertical direction by a rotation angle of less than or equal to 20 degrees.

Through the interval of wing section structure with first shock attenuation connection structure and second shock attenuation connection structure, the distance is more far away, then the ratio of first shock attenuation connection structure and second shock attenuation connection structure movement distance and the movement distance of swing arm body and fixed axle junction is big more, consequently locate first shock attenuation connection structure and second shock attenuation connection structure both sides tip can be when the great angle of both sides wheel deflection, with the motion state transmission of each other between both sides wheel, and reduce whole swing arm size that hangs as far as possible.
Optionally, the two sides of the wing-shaped structure of the swing structure form an acute angle with the horizontal direction, the width direction of the wing-shaped structure forms an acute angle with the horizontal direction, and the opening direction of the acute angle faces to one side of the shock absorber connected with the wing-shaped structure. Because the bumper shock absorber is connected and is passed through the rocking arm and connect the wheel, under the general condition, the bumper shock absorber has certain contained angle with vertical direction in its axial, and the bumper shock absorber top is inclined to frame or axle, and the bumper shock absorber bottom is inclined to the wheel, consequently, the angle that sways the structure both sides and set up more is favorable to being connected with the bumper shock absorber, reduces the resistance that the bumper shock absorber during operation was brought by the structure that sways.
Optionally, the first and second shock absorbing attachment structures are axially symmetric in a vertical direction about the fixed axis position. The casting of the swing arm body is convenient.
Optionally, the distance between the first damping connecting structure or the second damping connecting structure and the fixed shaft is greater than the distance between the limiting structure and the fixed shaft, so that the movement distance of the limiting structure is smaller under the condition that the rotation angles are the same, and the movement range of the limiting structure is convenient to reduce.
Optionally, the first shock absorption connecting structure and the second shock absorption connecting structure are respectively a first shock absorption connecting hole and a second shock absorption connecting hole. The first shock absorption connecting hole and the second shock absorption connecting hole are respectively connected with the first shock absorber and the second shock absorber through cap-shaped nuts.
