Abstract
An electric vortex magnetic drag arresting gear of a high-speed train relates to an arresting gear of a high-speed train and is arranged between the train body and a wheel shaft. The arresting gear comprises an electric vortex retarder and an axle cooling plant. The electric vortex retarder is fixedly connected between the train body and the wheel shaft, and the axle cooling plant is fixedly connected to the train body and comprises a wind inlet facing the train running direction, and a wind outlet facing the axle. An electromagnetic retarder is added to an axle of the arresting gear, and is used in coordination with a direct-touch friction braking mechanical braking system to realize the slowdown from the high-speed section to the low-speed section; then, the mechanical friction braking system is started to achieve complete braking; and besides, huge heat energy is generated in the braking process. An axle cooling plant is further arranged in the arresting gear, thereby further improving the cooling effect.
Description
Technical field
The utility model relates to a kind of brake equipment of high speed train, relates in particular to current vortex magnetic resistance braking device for high speed train.
Background technology
High speed train needs the fleet-footed while, also want and can in time stop, so high speed train relies on brake shoe and wheel friction force to brake unlike ordinary train, and will adopt advanced person's synthetical restraint means.Square being directly proportional of the kinergety of train operation and speed, as 700 tons of train deadweights, with 300 kilometers speed operations of speed per hour, its kinetic energy that has is 2,430 million Jiao's [ear].The high-speed train braking system must be that heat dissipates with these Conversion of energy within a certain period of time, or traction motor is become electrical generator mechanical energy is converted into electric energy feeds back to electrical network (rheostatic brake that also useful resistance consumption falls).The brake system of utilizing friction directly kinetic energy to be changed into heat is called mechanical braking sytem.The mechanical braking sytem of high speed train mostly is disc braking greatly, is that friction generates heat comes dissipation energy for brake lining and brake disc.Owing to be the direct friction contact, make that the wearing and tearing of brake component are very big, service life is very short, the requirement of braking when being difficult to adapt to high speed.
The utility model content
The utility model provides a kind of by noncontact friction braking means at above problem, in short time train is fit to the low speed that mechanical braking sytem starts by reducing at a high speed, simultaneously, the heat energy that train momentum is converted into can distribute fast, can not influence the current vortex magnetic resistance braking device for high speed train of axletree rigidity.
The technical solution of the utility model is: it is arranged between car body and the axletree, comprises current vortex retarder, axletree cooling mechanism, and current vortex retarder is fixedly connected between car body and the axletree; The axletree cooling mechanism is fixedly connected on the car body, comprises ventilation inlet, air outlet, and ventilation inlet is towards the vehicle operating direction, and air outlet is to axletree.
Described current vortex retarder comprises fixed mount, rotor, magnetic patch, flange, and flange is connected with axletree, and fixed mount is captiveed joint with car body by a suspension rod.
Described axletree cooling mechanism is one flat horn-like, captives joint with car body by pipe link.
Train needs glancing impact in high-speed cruising, as adopting direct contact type friction braking mechanical braking sytem, because it is difficult to the B.P. that reaches required, therefore can't use on high speed train.The utility model has added electromagnetic retarder on axletree, be used with direct contact type friction braking mechanical braking sytem, and the realization high regime is slowed down to low speed segment; Then, the mechanical friction brake system starts, and realizes braking fully.In addition, can produce great heat energy on axletree in the braking procedure, the utility model also is provided with the axletree cooling mechanism, because vehicle moves with hypervelocity, wind surface has cooling performance to axletree, pretended axletree cooling mechanism of the present utility model after, further improved the effect of cooling; Consider the way traffic of vehicle, the axletree cooling mechanism is provided with ventilation inlet with respect to axletree respectively towards the positive and negative direction of operation.
