Background technology
Vibrating wheels is as the groundwork device of road roller, and at operation and walking process, system is connected with vehicle frame by vibration reduction support, and directly contacts with manipulating object, and vibrational energy is passed to manipulating object.The technical contradiction of vibrating wheels vibration reduction support system, be to increase vibrational energy to improve the consolidation effect of road roller, reduction is passed to the vibration of vehicle frame with raising driver's operation comfort again, and avoids the machine sudden change of acceleration to the destruction on manipulating object surface.
At present, vibrating wheels is self-driven road roller, and the vibration reduction support system of its walking end is normally by one group of uniform vibrating wheels one side that is arranged on of damping block, and its installed surface is parallel with minute cloth cover, and namely installed surface is perpendicular to vibrating wheel shaft; Shock absorber in this type of vibration insulating system mainly is subjected to two kinds of stress, the shear stress that the gravity of namely getting on the bus produces, and the shear stress that produces of the driving moment during the machine walking; Separately in steering procedure, the end of walking divides shock absorber also to be subject to tensile stress; Vibration wheel of road roller damping block used uses rubber shock absorber usually.But according to the characteristic of elastomeric material, shearing and draw ratio compression more easily make defective shock absorber, and shear stress can be optimized by the suitable precompressed mode of vertical direction, therefore mainly should avoid making the rubber damping piece be in tension state; But conventional vibration insulating system stress when walking is for being turned round state, and the stress when turning to is tension state, thereby its service property (quality), application life have been subject to serious threat.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of good damping result is provided and helps to improve the vibration damping support device in vibration insulating system application life and use vibrating wheels and the road roller of this device.
The purpose of this utility model is achieved in that a kind of vibration damping support device, described device includes the welding bearing that is uniformly distributed on the vibrating wheels inner ring, and the welding bearing is positioned on same periphery, radial direction along vibrating wheels on described welding bearing is provided with installing plate, installing plate inserts in " U " shape opening of a U-shaped support that is made of biside plate and a base plate, and be plugged with respectively damping block between the biside plate of installing plate and U-shaped support, the base plate of described U-shaped support is connected with the drive plate of vibrating wheels.
A kind of vibration damping support device of the utility model, described damping block and installing plate and the contacted installed surface of U-shaped support are parallel to the wheel axis of vibrating wheels.
A kind of vibration damping support device of the utility model, the center of described drive plate is provided with connecting hole, and on the wheel axis that is centered close to vibrating wheels of this connecting hole, and described vibrating wheels realizes and being connected of drive unit by the connecting hole on drive plate.
A kind of road roller vibrating wheels, described vibrating wheels adopts above-mentioned vibration damping support device.
A kind of road roller, described road roller adopts above-mentioned vibrating wheels.
Compared with prior art, the beneficial effects of the utility model are:
The utility model passes through damping block perpendicular to the distribution plane, namely being parallel to the vibrating wheels wheel shaft installs, improved widely the stressed reasonability of damping block, make damping block be in compressive state in the most of the time, not only can take full advantage of the characteristic of damping block, extended again its application life, improved simultaneously the effectiveness in vibration suppression of damping block, further improved the consolidation effect of road roller and driver's handling comfort, the function of damping block has been maximized, optimization.
