The invention provides a brake head, a brake beam and a bogie. A roller shaft is arranged on the outer side of the brake head, a roller is arranged on the roller shaft in a sleeving mode and can rotate relative to the roller shaft, an end plate capable of limiting the roller to be disengaged towards the outer side is arranged on the outer side of the roller shaft, and the end plate does not protrude out of the outer edge of the roller in the radial direction. By the adoption of the structure, the roller shaft and the roller can be inserted into the sliding groove of the side frame of the bogie, and the roller can rotate around the roller shaft, so that when the brake head relieves a brake device, sliding friction is changed into rolling friction, and friction resistance between the brake head and the bogie is reduced; the end plate is fixed to the outer side of the roller shaft, the roller can be limited between the end plate and the brake head, and the roller can be prevented from transversely moving in the movement process or being separated from the roller shaft in the transportation process.

    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辊轴,辊子套设所述辊轴,并能够相对所述辊轴旋转,所述辊轴外侧设置有能够限制所述辊子向外侧脱离的端板,且所述端板沿径向方向不突出于所述辊子的外沿。采用如上结构,辊轴和辊子能够插装于转向架侧架滑槽,辊子能够绕辊轴转动,以使闸瓦托对制动装置进行缓解时,将滑动摩擦改为滚动摩擦,降低闸瓦托与转向架之间的摩擦阻力;端板固定于辊轴的外侧,并能够将辊子限位于端板与闸瓦托之间,能够防止辊子在运动过程中横向窜动或在运输中脱离辊轴。
