The invention relates to the technical field of mechanical helicopter rotor braking, in particular to a mechanical rotor braking device capable of preventing brake pads from tilting, brake control force acts on an upper brake pad assembly through a T-shaped pressing plate, and meanwhile, the brake control force is transmitted to a screw plug and a guide column through a rocker arm B, a rocker arm C, a rocker arm A and a rocker arm D to act on the upper brake pad assembly; meanwhile, pressure is applied to the upper brake pad assembly through three stress points, tilting of the upper brake pad assembly is eliminated, the upper brake pad assembly is pushed to move downwards to make contact with the brake disc and the lower brake pad assembly, friction torque is generated, the friction torque is increased along with increase of operating force, the effect of preventing the brake pad from tilting is achieved, and the brake efficiency is improved; local contact between the brake pad and the brake disc in the braking process is prevented, the problems of serious abrasion of local points of the brake pad caused by eccentric abrasion and the like are solved, and the braking frequency and the service life of the brake pad are improved. And use and maintenance of maintenance personnel are facilitated, popularization and application are easy, and high practicability is achieved.

    本发明涉及机械式直升机旋翼刹车技术领域,特别涉及一种防刹车片倾转的机械式旋翼刹车装置,刹车操纵力通过T型压板作用到上刹车片组件,同时通过摇臂B、摇臂C、摇臂A、摇臂D传递到螺塞和导柱作用到上刹车片组件,同时通过三个受力点对上刹车片组件施加压力,消除上刹车片组件的倾转,推动上刹车片组件下移与刹车盘和下刹车片组件接触,产生摩擦力矩,摩擦力矩随操纵力的增大而增大,具备防止刹车片倾转的作用,提高刹车效率,防止刹车过程中刹车片局部与刹车盘接触,消除偏磨导致的刹车片局部点的严重磨损等问题,提高刹车片刹车次数和使用寿命;且便于机务的使用维护,易于推广应用,具有很高的实用性。
