Problems solved by technology

[0003] Rail vehicles hold the wheel tread tightly when braking. The braking method is to use the friction between the wheel and the track to achieve braking. Since the contact area between the wheel and the track is relatively small, under the action of vehicle inertia, the vehicle still needs to Sliding for hundreds of meters to stop, the braking effect is not ideal, sometimes even can not achieve the braking effect, and it is easy to wear the wheels and tracks, so it is necessary to design a braking device that uses friction to achieve braking

Abstract

The invention relates to the field of rail brake, in particular to a brake device for rail traffic. The device comprises a bullet train and a rail, and further comprises a supporting assembly, a movable assembly and a friction assembly; the movable assembly comprises two symmetrically-arranged dual-connecting-rod mechanisms, each dual-connecting-rod mechanism comprises two symmetrically-arranged single-connecting-rod mechanism, each single-connecting-rod mechanism is composed of two short connecting rods and two long connecting rods, one ends of the short connecting rods are oppositely hingedto the middle of the outer side of the supporting assembly, one ends of the long connecting rods are oppositely hinged to the free ends of the two short connecting rods respectively, and the free endsof the long connecting rods are oppositely hinged to the lower half part of the supporting assembly separately. The problem that when the brake device brakes the bullet train, abrasion to wheels andrails are serious is solved, abrasion severity is lowered, and safety and stability are improved.

Description

technical field [0001] The invention relates to the field of rail braking, in particular to a braking device for rail transportation. Background technique [0002] Railway cars are used to pull trailers or other objects along the track. Rail transit has gradually become an important means of transportation between cities, carrying a large number of citizens' daily travel. Rail transit safety has naturally become the most important issue. Now Some railway moving car brake devices all use wheel brakes. The most common brake method used by rail vehicles is brake shoe brakes, which are tile-shaped brake blocks made of cast iron or other materials. [0003] Rail vehicles hold the wheel tread tightly when braking. The braking method is to use the friction between the wheel and the track to achieve braking. Since the contact area between the wheel and the track is relatively small, under the action of vehicle inertia, the vehicle still needs to Sliding hundreds of meters to stop, ...
