The invention discloses a pneumatically-driven emergency auxiliary deceleration system, and relates to the field of aircraft brake equipment, and the technical scheme of the invention is as follows: the pneumatically-driven emergency auxiliary deceleration system comprises a driving bin, a guide piece, a steel block and a pneumatically-driven piece; the driving bin is vertically arranged at the upper top of the undercarriage, a sliding cavity is vertically formed in the driving bin, and the guiding piece is axially arranged in the sliding cavity; the steel block is in sliding fit with the guide piece, and is in sliding fit with the inner wall of the sliding cavity at the same time; air holes are formed in the upper end and the lower end of the driving bin correspondingly and communicate with the air pressure driving piece correspondingly. Pressure can be provided for the undercarriage, so that the friction force between an aircraft tire and the ground is increased, and the auxiliary braking effect is achieved.

    本发明公开了一种气压驱动紧急辅助减速系统,涉及飞机制动设备领域,本发明的技术方案,包括驱动仓、导向件、钢块和气压驱动件;所述驱动仓竖向设置于起落架上顶部,所述驱动仓内竖向设置有滑动腔,所述滑动腔的内部轴向设置有所述导向件;所述导向件上滑动配合有所述钢块,所述钢块同时与所述滑动腔的内壁滑动配合;所述驱动仓的上下端部分别设置气孔,所述气孔分别与所述气压驱动件连通。能够实现对起落架提供压力,进而加大飞机轮胎与地面的摩擦力,达到辅助制动的效果。
