Vehicle and equalizing suspension thereof

Abstract

Disclosed is an equalizing suspension, which comprises a crank throw (41,42), and a damping device, wherein the crank throw (41,42) is a bent structure; one end of the crank throw (41,42) is hinged with an axle (21,22), the other end thereof is connected to one end of the damping device; and the bend of the crank throw (41,42) is hinged with a support (31,32) on a frame (1). The equalizing suspension of the structure realizes the damping function of the equalizing suspension by means of the crank throw and the damping device; and the balance of the suspension is realized by means of the crank throw swings instead of being guaranteed by an oil cylinder. Compared with oil gas suspension, the design of an equalizing oil path is reduced via the equalizing suspension, and therefore it has the advantages of a simple oil path, low cost and good vibration damping effect. In addition, a vehicle with the above-mentioned equalizing suspension is also disclosed.

Description

technical field [0001] The invention relates to the technical field of suspensions, in particular to a balanced suspension with good buffering effect and simple structure. The invention also relates to a vehicle with a balanced suspension as described above. Background technique [0002] Suspension is the connecting device between the axle and the frame. Its function is to transmit the force and moment acting between the wheel and the frame, buffer the impact force transmitted to the frame from the uneven road surface, and attenuate the vibration caused by it. To ensure that the car can run smoothly. [0003] In the prior art, common suspension forms mainly include leaf spring suspension, oil-pneumatic suspension, air suspension and the like. When the vehicle crosses the uneven road surface, in order to prevent the problem of partial suspension of the axle, the suspension should have a certain balance ability. Common suspension structures include leaf spring balanced suspe...

AI Technical Summary

Problems solved by technology

[0004] like figure 1 as shown, figure 1 It is a structural schematic diagram of a leaf spring balance suspension in the prior art. The leaf spring balance suspension usually includes a balance beam 3', a leaf spring 4', two ends of the balance beam 3' and two ends of the leaf spring 4' They are respectively connected to the front axle 2' and the rear axle 1'. The leaf spring balance suspension has a simple structure and low cost, but the shock absorption effect is not good

[0005] Hydro-pneumatic suspension can usually achieve balance through electro-hydraulic control, but its oil circuit connection and control are more complicated, and the cost is higher; in addition, since the oil-pneumatic suspension cylinder of the hydro-pneumatic suspension can only be set on the side of the frame, so the hydro-pneumatic suspension Suspension is difficult to arrange on twin tire axles
