Abstract
A friction clutch for a draft gear assembly includes two outer stationary plates having outer surfaces engageable with the inner surfaces of a gear housing. A slot formed in each outer stationary plate receives a lubricating insert to provide lubrication and prevent clutch sticking after closure and during a release of such gear. A pair of movable plates have outer surfaces fractionally engaged with the inner surfaces of such outer stationary plates. A pair of inner stationary plates have outer surfaces fractionally engaged with the inner surfaces of such pair of movable plates. An inner surface of each inner stationary plate is tapered. Another slot formed in each tapered stationary plate adjacent it's outer surface receives another lubricating insert. A center wedge having correspondingly tapered surfaces fractionally engages an upper surface of a respective one of such pair of wedge shoes for absorbing energy during closure.
Description
The present invention relates in general to the friction-type traction component, particularly, the present invention relates to a kind of friction axis coupling, and it can be used for improving and improving the quality of traction component, makes the traction component after the improvement improve the rated load ability; It also can be used in the later-model friction-type traction component, this traction component has higher rated load ability, at least can absorb a part of vibrations or drawbar load, they act on normally in the train marshalling with when normally moving on the line on the center sill of train.
As everyone knows, in railway technology, before the present invention, the friction-type traction component is widely used in having for many years in the railway industry.These traction components are contained in the slotted hole, and along its longitudinal axis, and it is promptly inner to be positioned at vehicle unitor rear portion in the train center sill for this slotted hole.In this case, these traction components most of absorbing vibration and tractive force at least.Vibrations that train is suffered and tractive force when normally train normally moves on the line, act on the center sill in the mode of alternation.
In the prior art of friction-type traction component, representative can for example see US Patent 2916163; 3178036; 3447693; 4576295; 4645187 and 4735328.The traction component of these prior arts even be not all also to be wherein most of, once or still was used for railway industry in the past in the present invention.In addition, except that US Patent 4576295 and 4735328, above-mentioned remaining all kinds of patents all belongs to cessionary of the present invention to be owned.By the above-mentioned all kinds of patents of reference comprehensively in this article with related content.
Those people that are familiar with friction-type traction component designing technique generally believe, must be able to maintain certain minimum cushioning ability at least when these traction components are served on the line.This minimum ability has been made regulation by U.S. railway association (AAR), and describes in detail in the AAR standard.For example, the minimum absolute magnitude of friction-type traction component with regulation is at least 36000 pounds.Rated quantity is lower than 36000 pounds traction component, presses the not granted use aboard of regulation of AAR.
In addition, must be pointed out that the work of friction axis coupling can reach this minimum rated quantity being no more than under the situation that is 500000 pounds of antagonistic forces (or pressure) to the maximum of regulation, antagonistic force acts on the train center sill when train marshalling and operation.This maximum effect pressure needs, so that can and/or not damage other crucial train parts and/or not destroy train under the situation about being conveyed goods at jumping-up coupler axle head not, absorbs high-octane vibration rapidly.
