Description
Technical Field
The utility model relates to a braking system technical field, concretely relates to green skin train brake block forked tail piece.
Background
In a braking system, a brake pad is the most critical safety part, and the quality of all braking effects plays a decisive role. At present, the existing brake pad generally comprises a steel backing, a dovetail block fixed on one side face of the steel backing and a friction plate bonded on the dovetail block, and the effect of vehicle deceleration braking is achieved by the contact friction between the brake pad and a brake disc or a drum in the use process. It is known that a great deal of heat is generated in the friction process, if the heat is not effectively eliminated, the service life of the brake pad is affected, especially for a brake system used by a train, the inertia of the train during running is large, so that the braking force required during braking is large, the heat and noise generated in the friction process are also large, the heat dissipation effect of the brake pad in the prior art is poor, the service life of the brake pad used for the train is short, and the noise generated by friction is large, the use effect of the brake pad is affected, and therefore the requirements of people cannot be met.
SUMMERY OF THE UTILITY MODEL
