Description
Technical field
The utility model relates to a kind of brake cooling device, refers to use in a kind of air extractor vent of directly cold air directly being sent into the brake disc or the Brake drum a kind of brake cooling device of the better cooling performance of acquisition especially.
Background of invention
Along with growth in the living standard, the steam turbine car quantity that people had constantly increases, because the vehicle that use are very quick on speed, therefore, in the consideration of safety, just need braking system is done the design of an overall property, no matter to guarantee the being safety that locomotive, automobile and popular transportation means are expert at and are reached.And at present in the braking system of vehicle, between brake shoe and brake disc or the Brake drum since in brake continuously when underspeeding, make brake shoe and brake disc or the Brake drum resistance that produces that reciprocally rubs, so that car retardation or to stopping; Yet, under high vehicle speeds, to in a short time, promptly speed be fallen, therefore inevitably with this brake shoe, with the sizable friction force of generation between disc or Brake drum of braking, and produce quite hi-heat heat thereupon, under this high temperature, the friction coefficient that extremely should make brake shoe reduces and causes the phenomenon of defective brake.On the other hand, the problem of finding Brake fluid in the process that reality is used may be ignored for a long time, because the high temperature that brake is produced can make the oily temperature rise of the Brake fluid of being responsible for reception and registration power equally, when the warm height of the oil of Brake fluid promptly can produce the gasification phenomenon after to a certain degree, because the density ratio liquid of gas is low, in case therefore Brake fluid produces gasification, the efficient of Brake fluid transferring power is significantly reduced, cause the consequence of gas lock defective brake easily, quality owing to Brake fluid differs in addition, the lasting time also not necessarily, very easily make moisture produce gasification in case there is the moisture intrusion after braking, to produce high temperature, can be flexible during brake, cause the problem of brake insufficient pressure simultaneously.So, the probability that the traffic accident accident make to take place greatly improves, and leads to the tragedy of major traffic accidents, can't obtain to ensure for the life security of steerman.In addition, truck can carry large water tank and constantly blindly spray water when brake, cause brake wheel steel ring to cool off suddenly by high temperature, the danger that causes Brake drum to break easily, and if Brake shoe blocks or damage of the bearing causes high temperature, because the tonnage power of car own is big, drives extremely difficulty and discover up to defective brake or send smell of scorching and just know defective brake, but cause serious traffic accident accident owing to late.
Present traditional braking system, when in transportation means, using, the heat of the friction force that produces between brake shoe and brake disc or Brake drum is not done the consideration of an overall property, so this can must be designed the consideration that braking system causes the frictional heat energy that has a strong impact on to be managed to do on the safety, the more necessary action how this brake shoe and brake disc are done to lower the temperature designs, but braking system will be avoided the too high problem that becomes friction coefficient to reduce of Yin Wendu fully, be very difficult, thereby, the factor that must consider, not merely be that temperature is done alarm, also will be suitably cooled off.For making in the vehicle ', can obtain vehicle single-piece situation and being controlled fully, therefore, braking system situation is wherein also needed be monitored by design.
Because traditional braking system is to utilize a brake disc or brake wheel hub and brake shoe bestowing by strength, produce a friction force, the wheel of high speed rotating underspeeds even stops and making originally by this friction force, and desire in a short time, to reach this purpose, just need have a great friction force to realize, what come with this friction force is a hi-heat heat.In same brake power, under the different temperature, needed brake distance is had nothing in common with each other, owing to can't estimate required brake distance, has improved the probability that the traffic accident accident takes place.Owing to avoiding this hi-heat heat to cause the friction coefficient of brake shoe to reduce, make braking system malfunctioning.
Summary of the invention
Therefore, main purpose of the present utility model is to provide a kind of brake cooling device, make caution of its temperature that can monitor each parts of braking system at any time and start-up temperature and cooling mechanism, too high and cause friction coefficient to reduce to avoid Yin Wendu, and then guarantee traffic safety and smooth traffic.
