Rocker type suspension track for spreading machine

Abstract

The invention discloses a rocker type suspension track for a spreading machine, comprising a rubber track (12) as well as a guide wheel (1), a guide wheel support system (2), a driving wheel system (14), a tension spring system (4), a track girder (9) and a thrust wheel rocker system (13) which are positioned in the rubber track (12), wherein the thrust wheel rocker system (13) is positioned below the track girder (9). The thrust wheel rocker system (13) is capable of realizing longitudinal oscillation so as to realize the functions of shock absorption and load bearing of a machine body; the driving wheel system (14) is capable of realizing the function of supplying power; and the guide wheel (1), the guide wheel support system (2) and the tension spring system (4) are capable of realizing the functions of transferring the power, tensioning the rubber track (12) and playing a partial buffer effect.

Description

technical field [0001] The invention relates to a swing-type suspension crawler belt, which is especially suitable for a paver. Background technique [0002] The fuselage, track beam and rollers of traditional paver are rigidly connected together by bolts. In conventional paving, due to the slow paving speed, the impact frequency of the road on the rollers is low, and the momentum of the impact force is also low. Smaller, less impact on the stability of the vehicle body, enough response time for leveling, little impact on the paved road surface, when the paver wants to achieve fast paving, the impact frequency and impact of the road on the rollers The force momentum will increase with the acceleration of the paving speed, and the vibration frequency and amplitude of the body will also increase. When the vibration frequency and amplitude reach a certain value, the leveling system will not have enough response time to adjust the screed The attitude of the pavement will be gre...

Problems solved by technology

[0002] The fuselage, track beam and rollers of traditional paver are rigidly connected together by bolts. In conventional paving, due to the slow paving speed, the impact frequency of the road on the rollers is low, and the momentum of the impact force is also low. Smaller, less impact on the stability of the vehicle body, enough response time for leveling, little impact on the paved road surface, when the paver wants to achieve fast paving, the impact frequency and impact of the road on the rollers The force momentum will increase with the acceleration of the paving speed, and the vibration frequency and amplitude of the body will also increase. When the vibration frequency and amplitude reach a certain value, the leveling system will not have enough response time to adjust the screed attitude, the pavement quality will be greatly affected

[0003] It can be seen that the existing rigid connection between the track beam and the rollers cannot play a good role in shock absorption and buffering, so it is urgent to develop a new connection method
