The invention provides a brake head, a brake beam and a bogie, a sliding block part is arranged on the outer side of the brake head, clamping grooves are formed in the front side and the rear side of the sliding block part, pulley mechanisms are installed in the two clamping grooves, each pulley mechanism comprises a pulley, and at least part of each pulley is arranged in the corresponding clamping groove in a protruding mode. By the adoption of the structure, the sliding block part of the brake head can be clamped in the sliding groove of the side frame of the bogie, when the brake head does not make contact with wheels for braking, the brake head mainly bears the gravity of the brake head, the brake head makes contact with the sliding groove through the pulley protruding out of the clamping groove, sliding friction is changed into rolling friction, and friction resistance between the brake head and the bogie is reduced; when the brake head is in contact with a wheel for braking, the angle of the brake head is changed due to the fact that the brake head bears pressure in the wheel direction, the brake head makes contact with the sliding groove through the sliding block part, the sliding block part bears main braking tangential force, and a pulley mechanism is prevented from being damaged due to the fact that the sliding block part bears too large pressure.

    本发明提供一种闸瓦托、制动梁和转向架,所述闸瓦托外侧设置有滑块部,所述滑块部前后两侧设置有卡槽,两所述卡槽内安装有滑轮机构,所述滑轮机构包括滑轮,所述滑轮至少部分突出设置于所述卡槽。采用如上结构,闸瓦托的滑块部能够卡装于转向架侧架滑槽内,在闸瓦托未与车轮接触制动时,其主要承受自身重力,闸瓦托通过突出于卡槽的滑轮与滑槽接触,将滑动摩擦变为滚动摩擦,减小闸瓦托与转向架之间的摩擦阻力;在闸瓦托与车轮接触制动时,闸瓦托受车轮方向的压力,导致闸瓦托角度发生变化,此时闸瓦托通过滑块部与滑槽接触,并使滑块部承受主要制动切向力,防止滑轮机构承受过大压力而损坏。
