The invention discloses a shaft end hydraulic band-type brake. The shaft end hydraulic band-type brake comprises a base, supporting frames, a guide mechanism, pressing rods, a pressing shaft, a pushing sleeve, an oil cylinder, braking mechanisms, a shell, a first liquid separation block, a first one-way valve, a temporary storage mechanism, an extrusion mechanism, a second one-way valve, a long-stroke electromagnet and a second liquid separation block; and during braking, annular electromagnets arranged in the braking mechanisms are energized and attract attraction sleeves, the long-stroke electromagnet pushes the extrusion mechanism to press non-Newtonian fluid into arc-shaped grooves, transient solid is formed due to the fact that the viscosity of the non-Newtonian fluid in the arc-shaped grooves is extremely high at the moment when brake pads make contact with a high-speed working shaft to brake and buffer vibration of the working shaft, and the non-Newtonian fluid cools the workingshaft until the working shaft is completely stopped along with reduction of the speed of the working shaft. The device is simple in structure, and the functions of braking, vibration buffering and cooling are achieved through the change of the viscosity of the non-Newtonian fluid, so that the service life of the brake pads is prolonged, working vibration is reduced, and high practicability is achieved.

    本发明公开了一种轴端液压抱闸,包括底座、支撑架、导向机构、压杆、压轴、推套、油缸、刹车机构、壳体、第一分液块、第一单向阀、缓存机构、压出机构、第二单向阀、长行程电磁铁、第二分液块,制动时,刹车机构内设的环形电磁铁得电与吸合套吸合,长行程电磁铁推动压出机构将非牛顿流体压入弧形槽,由于刹车片与高速工作轴接触的瞬间,弧形槽内的非牛顿流体粘度极高而形成短暂的固体对工作轴进行刹车以及缓冲振动,随着工作轴速度的降低,非牛顿流体对工作轴进行冷却直到工作轴完全停止。该装置结构简单,利用非牛顿流体粘度的变化实现刹车、缓冲振动及冷却功能,提高了刹车片的使用寿命及降低了工作振动,具有很强的实用性。
