The utility model compared with prior art has the following advantages:
The utility model owing to being provided with the friction shoe of locomotive control on locomotive, made locomotive produce braking force by friction shoe and plummer friction, and plummer is locomotive wheel track or the special friction plate be arranged in parallel with described wheel rail or special rail, in other words, locomotive brake also arranges a set of independently system in addition, the contact being not only locomotive wheel and rail realizes emergency braking, therefore when emergency braking, by implementing the system of locomotive brake of the present utility model, substantially increase braking effect.The basis of particularly braking between existing locomotive wheel and rail increases between friction shoe described in the utility model and plummer and produce cliding friction, and make locomotive produce synthetical restraint, thus locomotive is promptly stopped, solve existing locomotive to rely on and single the defect of emergency brake and locomotive under the effect of inertia, also can not can produce the defect slided to after wheel shaft braking, thus avoid the grave accident that knocks into the back, therefore the reliability of the utility model to the technical scheme of the emergency braking of locomotive obtains qualitative leap.
The utility model between existing wheel rail, arrange special friction plate or special rail produces braking force to make locomotive emergency braking to realize cliding friction to locomotive as with friction shoe friction: 1) can protect wheel rail, avoid friction shoe direct friction and bring the infringement to wheel rail, being conducive to the service life extending wheel rail; 2) special friction plate or special rail are set separately, be convenient to flexible arrangement and friction shoe is set, particularly can carry out clamping from the both sides of described special friction plate or special rail and make locomotive snap catch, further increase the emergency braking effect that cliding friction brings, namely can promptly locomotive be stopped, solve existing locomotive to slide also producing under the effect of inertia after wheel shaft braking, thus avoid the generation of the grave accident knocked into the back; 3) special friction plate or special rail are set separately, design condition is provided for how improving force of sliding friction, in enforcement, do not need to carry out any change to the structure of original wheel rail with laying, do not carry out destroying to the safety performance parameter of original design of wheel rail and disturb, under the prerequisite keeping original safety performance, the safety performance of whole locomotive operation system is further improved, cost is also controlled effectively simultaneously; Otherwise, just need again to design and Performance Evaluation wheel rail, safety performance and the design parameters of original wheel rail certainly will be changed, greatly increase cost, but also the life-span of wheel rail can be reduced.
In a word, the utility model is except can utilizing as auxiliary brake system when existing brake system coexists, also can as main brake system: because existing locomotive slides also producing under the effect of inertia after wheel shaft braking, this sliding can affect emergency braking effect and cause a serious accident, and can rail level be damaged, particularly after wheel shaft braking, it is no longer friction of rolling between wheel and track, and become cliding friction, like this, both wheel and track had been produced and slided scratch, also can produce a large amount of heats, cause the material property changing wheel and track, greatly reduce the life-span of wheel and track, and have employed the utility model, except producing large friction force and can completely locomotive being stopped, key this before stopping of existing locomotive is slided the breaking-up produced wheel rail to transfer to special friction plate or between special rail and friction plate, instead of between original wheel and track, therefore substantially prolongs the life-span of wheel and track.
