Problems solved by technology

[0002] For road rollers, the exciting force of the rollers in the working state is large, and the exciting force from the rollers is transmitted to the cab through the frame, causing the cab to shake and vibrate easily. The comfort level is low, and the driver is prone to fatigue, which reduces the safety of driving

Embodiment 1

[0071] Such as Figure 6 As shown, this embodiment provides a vibration damping device. Such as Figure 7 and Figure 8 As shown, the vibration damping device is disposed between the cab 100 and the vehicle frame 200 of the road roller 10 , including a first vibration damping assembly 300 and a second vibration damping assembly 600 . Wherein the first end of the first damping assembly 300 is connected with the vehicle frame 200 or the cab 100, of course, it can also be connected with the vehicle frame 200 or the cab 100 at the same time, and the vehicle frame 200 and the cab 100 can be tensioned to improve the height of the cab. Rigidity between 100 and frame 200. The second damping assembly 600 includes a damping and damping structure 602 , and the two ends of the damping and damping structure 602 are respectively connected with the cab 100 and the vehicle frame 200 .

[0072]The road roller in this embodiment is used for compacting construction materials for paving roads...

Embodiment 2

[0080] Such as Figure 7 and Figure 8 As shown, this embodiment provides a vibration damping device. In addition to the technical features of Embodiment 1 above, this embodiment also includes the following technical features.

[0081] The first damping assembly 300 has a first working state and a second working state. In the first working state, the first damping assembly 300 is rigidly connected or elastically connected between the frame 200 and the cab 100 to tension the frame 200 and the cab 100 . In the second working state, the second end of the first damping assembly 300 is disengaged from the cab 100 or the vehicle frame 200 relative to the first end (it can be understood that when the first end of the first vibration damping assembly 300 is positioned on the vehicle frame 200 When the first end of the first damping assembly 300 is on the cab 100, the second end of the first damping assembly 300 is separated from the cab 100; The vehicle frame 200 is disengaged), or...

Embodiment 3

[0086] Such as Figure 9 As shown, this embodiment provides a vibration damping device. In addition to the technical features of any of the above embodiments, this embodiment also includes the following technical features.

[0087] The first damping assembly 300 includes one or more support assemblies connected to the vehicle frame 200 . When the first vibration damping assembly 300 is in the first working state, the support assembly abuts against the cab 100 , and when the first vibration damping assembly 300 is in the second working state, the support assembly is separated from the cab 100 .

[0088] The supporting assembly includes a first driving assembly, a first supporting part 402 and a second supporting part 406 . Wherein, the first supporting portion 402 protrudes from the surface of the vehicle frame 200 toward the cab 100 and is provided with a supporting shaft 404 . The second support part 406 is movably connected with the first support part 402 . The first driv...

Abstract

The invention provides a damping device, a road roller and a control method of the road roller. The damping device is arranged between a cab and a frame of the road roller and comprises a first damping assembly and a second damping assembly, wherein the first end of the first damping assembly is connected with the frame and the cab, the frame and the cab can be tensioned so as to improve the rigidity between the cab and the frame, the second damping assembly comprises a damping vibration attenuation structure, and the two ends of the damping vibration attenuation structure are connected with the cab and the frame. According to the technical scheme, the vibration reduction effect can be achieved in the normal working state of the road roller, and the resonance degree of the cab can be reduced when the road roller starts vibration and stops vibration, therefore, according to the technical scheme, the driving comfort and the driving safety degree of the road roller are improved, and the maintenance cost of the road roller is reduced.

Description

technical field [0001] The invention relates to the technical field of road rollers, in particular to a vibration damping device, a road roller and a control method for the road roller. Background technique [0002] For road rollers, the exciting force of the rollers in the working state is large, and the exciting force from the rollers is transmitted to the cab through the frame, causing the cab to shake and vibrate easily. The level of comfort is low, and the driver is prone to fatigue, reducing the safety of driving.
