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

Embodiment Construction
[0027] The present invention will be further described below in conjunction with accompanying drawing.
[0028] Such as figure 1 with figure 2 As shown, the present invention mainly consists of rubber track 12, and guide wheel 1 located in rubber track 12, guide wheel bracket system 2, drive wheel system 14, tension spring system 4, track beam 9, and the track beam 9 below Roller pendulum system 13 forms.
[0029] Such as Figure 8 with Figure 9 As shown, the crawler beam 9 plays the role of the overall skeleton and support, and is connected with the fuselage through the connecting frame 10 to support the fuselage.
[0030] Such as image 3 As shown, the main function of the driving wheel system 14 is to drive the rubber track 12 to provide power for the whole system by rotating itself. Its main components include a driving wheel 35 , a reducer 34 , and a hydraulic motor 32 . Wherein: the hydraulic motor 32 is connected with the speed reducer 34 through the bolt 31 to ...
