A kind of light-duty linkwork of full landform endless-track vehicle
Technical field
The invention belongs to a kind of linkwork of full landform endless-track vehicle.
Background technology
Full landform endless-track vehicle is generally made up of front vehicle body, aftercarriage and the part of linkwork three, can be in snowfield, sand Travelled in the various landform such as unconcerned, marsh and muddy jungle, additionally it is possible to carry out amphibious operation.Its handling capacity master to complicated landform Two linkworks for saving car bodies are designed before and after depending on connection.At present, divided from mechanism's number of degrees of freedom, full landform creeper truck Linkwork be broadly divided into three kinds:Single-degree-of-freedom linkwork, i.e., front and rear two sections car body is merely capable of realizing divertical motion; Two degrees of freedom linkwork, i.e., front and rear two sections car body can realize divertical motion and elevating movement;Joint with three degress of freedom mechanism, i.e., Front and rear two sections car body can not only realize divertical motion and elevating movement, moreover it is possible to realize relative twisting movement.
The full landform creeper trucks of Sweden BV206 use a kind of two degrees of freedom linkwork.This linkwork can be real Be horizontally diverted and the low-angle pitching of existing vehicle, but relative torsion is unable between front and rear two sections car body, and such linkwork is not Only to bear bending load, it is necessary to bear the relative torsion load between two section car bodies.Therefore, the linkwork is main by forging The solid parts composition made, to meet the intensity, rigidity, the stability requirement that bend and reverse under various operating modes.Therefore, should The shortcoming of linkwork be exactly conduct oneself with dignity it is larger, and its number of degrees of freedom, purpose lack cause using the type linkwork entirely The handling capacity of shape creeper truck is restricted.
The full landform creeper trucks of Finland NA-140 use a kind of two degrees of freedom linkwork.This linkwork can be real Existing vehicle is horizontally diverted and larger angle pitching, is that the linkwork devises two the reason for realize larger angle pitching Pitching oil cylinder, controls front truck pitching and rear car pitching respectively.But the linkwork can not equally realize it is front and rear two section car body it Between relative torsion, it is also necessary to while bearing bending load and torsional load.Therefore, in order to meet its intensity under various operating modes, Rigidity, stability requirement, the linkwork are mainly made up of the solid parts for forging.Obviously, the shortcoming of the linkwork is same Sample is that deadweight is larger, and handling capacity using the full landform endless-track vehicle of the type linkwork is still restricted.
Russian " knight " full landform creeper truck uses a kind of joint with three degress of freedom mechanism.This linkwork is not only Can realize vehicle be horizontally diverted with larger angle pitching, and the relative rotation between front and rear car body can be realized.But The linkwork is mainly used in heavy full landform endless-track vehicle, general more than load-carrying 30t.Therefore, deadweight is larger to a certain degree On limit its use.
The full landform creeper truck of " the boa formula " of Harbin First Machinery Group Corporation Limited uses a kind of Three Degree Of Freedom hinge Connection mechanism.This linkwork can not only realize vehicle be horizontally diverted with larger angle pitching, and before and after can realizing The relative rotation of car body.The linkwork has been successfully applied on the full landform creeper truck product of " boa formula " 30t, 5t, 3t series. But the linkwork structure determines that its quality is larger in itself, the lightweight demand of engineering machinery field is unsatisfactory for, also no longer Suitable for the full landform endless-track vehicles of 2t and 1.5t.
