Combined type rubber metal joint bearing and method

Abstract

The invention provides a combined type rubber metal joint bearing and method. The metal joint bearing comprises a joint inner ring and a joint outer ring. A core shaft is embedded into the joint inner ring. The joint outer ring is sleeved with a rubber bushing. The joint outer ring abuts against an inner sleeve of the rubber bushing. A rubber check ring is embedded between the core shaft and the inner sleeve in a sleeved manner. An inner check ring of the rubber check ring abuts against the core shaft. An outer check ring of the rubber check ring abuts against the inner sleeve of the rubber bushing. According to the joint bearing, the joint outer ring is sleeved with the rubber bushing, and with the rubber bushing, the radial bearing ability and the radial buffering performance of the metal joint bearing are improved. The rubber check ring is embedded between the core shaft and the rubber bushing, the rubber check ring can generate damping force to stop deflection of the core shaft when the core shaft deflects, and thus vibration and noise generated in the deflection process of the core shaft can be reduced substantially.

Description

technical field [0001] The invention relates to a metal joint bearing, in particular to a metal joint bearing capable of improving radial bearing capacity and vibration and noise reduction performance. Background technique [0002] Dedicated passenger lines, heavy-haul freight, and urban rail transport have developed rapidly in China in recent years. The bogie is an important part of the rail vehicle. The rubber joints and rubber damping elements in the rail vehicle have good vibration damping characteristics, ease various interactions between the vehicle and the line, reduce vibration and impact, and improve vehicle operation. stability, safety and reliability. Current rubber and metal joints have the following limitations: [0003] 1) The current rubber joint is vulcanized by a rubber layer and a metal inner jacket. Due to the rubber layer, the joint has a certain bearing capacity and vibration and noise reduction capacity in the radial direction, but it limits the defle...

AI Technical Summary

Problems solved by technology

[0012] The technical problem to be solved by the present invention is: in view of the fact that the current joint bearings are difficult to achieve deflection buffering and large carrying capacity at the same time, and it is difficult to meet the needs of rapidly developing rail vehicles, a new type of joint bearing with deflection buffering and large carrying capacity is proposed, which can improve the speed reduction. Metal joint bearings with high vibration and noise reduction capabilities
