The anti-eccentric-wear device for the locomotive brake shoe comprises a brake shoe bracket and a brake shoe body installed on the right side of the brake shoe bracket through a guide mechanism, and the end, away from the brake shoe bracket, of an elastic adjusting mechanism is attached to the left side face of the brake shoe body. Automatic gap adjusting mechanisms used for adjusting the position of the brake shoe body are symmetrically installed on the front side face and the rear side face of the upper end and the lower end of the brake shoe bracket. According to the anti-eccentric-wear device for the locomotive brake shoe, guide blocks in the guide mechanisms slide in guide grooves, eccentric wear caused by deviation is avoided, it is guaranteed that the brake shoe body can accurately make contact with a wheel tread in the later period, and the brake shoe body can be adjusted through multiple sets of elastic adjusting mechanisms installed between the brake shoe bracket and the brake shoe body; therefore, each position of the brake shoe body can be stressed more uniformly, the abrasion of each part of the brake shoe body is relatively balanced, the whole friction surface of the brake shoe body can be fully utilized, the braking efficiency is improved, and the service life of the brake shoe is prolonged.
本发明公开了一种机车制动机闸瓦用抗偏磨装置,包括闸瓦托架,以及通过导向机构安装在闸瓦托架右侧的闸瓦本体,弹性调节机构远离闸瓦托架的一端与闸瓦本体的左侧面贴合设置,所述闸瓦托架上下两端的前后两侧面均对称安装有用于对闸瓦本体的位置进行调整的间隙自动调整机构。该机车制动机闸瓦用抗偏磨装置,通过导向机构中的导向块在导向槽内的滑动,避免因偏移而产生偏磨,保证后期闸瓦本体能准确的与车轮踏面接触,通过安装在闸瓦托架和闸瓦本体之间的多组弹性调节机构,从而可使得闸瓦本体的各个位置受力更加均匀,保证闸瓦本体各部位的磨损相对均衡,这样可以充分利用闸瓦本体的整个摩擦面,提高制动效率,延长闸瓦使用寿命。
