Description
Technical field
The present invention relates to the macromolecular sustained die head of locomotive (or claiming train, train), be used for respectively saving hitch bonded assembly pad between the railroad car, also can be used as the pad of other powerful extruding.
Background technology
Locomotive (also claiming train, the train) more piece of ining succession mutually railway carriage, each saves between the railway carriage and is interconnected by bindiny mechanism, and the existing bindiny mechanism that uses is generally spring clay hitch.When railway carriage is connected with railway carriage, have very big impact, spring clay hitch exists the great efforts that are hit, and vehicle body is unstable; Oscillation Amplitude is big, and parts damage easily, and spring and clay are installed in the casing; Sometimes casing is squeezed broken back clay and is flow to the outside, the maintenance trouble.And the power that spring clay hitch can only bear 850KN, speed per hour are 60-70 kilometer (mainly referring to shipping load-carrying locomotive), thus this limitation of the technology the development of railway transportation.
Summary of the invention
The objective of the invention is provides a kind of and becomes pad with processing of high molecular material in order to overcome the shortcoming that prior art exists, and the steel axle is supporting with being connected; Has the intensity height, good springiness, and incompressible distortion; High-and low-temperature resistance; Anti-tanning by the sun, contact performancies such as grease resistance, fuel oil, and the macromolecular sustained die head of anti abrasive locomotive.
Another object of the present invention provides the job operation of the macromolecular sustained die head of locomotive.
The technical scheme of the macromolecular sustained die head of locomotive of the present invention is: it is characterized in that an oblate body, the center of body is shaped on axis hole, is cavity in the body, and outer wall is shaped on location lug in the body both sides.
The invention discloses the macromolecular sustained die head of a kind of locomotive, an oblate body since each pad when using through connecting the steel tandem shafts, so be shaped on axis hole at the center, axis hole be connected the steel axle and match.Each railway carriage of locomotive has very big impact when connecting, hitch is connected, and one side is pushed and the opposite side stretching when turning driving, so be cavity in the body, is suitable for elastic deformation.Cushion rubber is except by connecting the steel tandem shafts, and between each cushion rubber, steel plate is installed, and is shaped on knock hole in the steel plate; Therefore, all be shaped on location lug in the both sides of body outer wall, location lug inserted in the steel plate knock hole when assembling was used; Make each cushion rubber independent, keep an integral body again.Present technique scheme locomotive polymeric buffer spacer is flexible good, and incompressible distortion is high temperature resistant, and is low temperature resistant, sun-proof, and contact performancies such as grease resistance, fuel oil, and wear-resistant.Adopt this macromolecular sustained die head and the bindiny mechanism that is connected between each railway carriage of locomotive that steel axle etc. forms, make the holding capacity of shipping load-carrying locomotive can reach 2000KN, speed per hour improves railway transport capacity more than 180 kilometers widely.
The macromolecular sustained die head of locomotive of the present invention, described location lug is 3-6 in every side of body, the location lug of both sides staggers mutually, promptly not in same symmetric position.Knock hole in the steel plate can be a through hole, and can make the 6-12 hole, can all get in the knock hole after the both sides location lug staggers, and receives force intensity good.Said location lug is 4 in every side preferred plan of body, and the location lug of the both sides 45 that staggers mutually matches with the structure of 8 knock holees in the steel plate like this, and is stressed more reasonable.
