The invention belongs to the aviation technology. A hydraulic braking system comprises double control of helicopter undercarriage wheel braking. The control device for wheel braking of the helicopterundercarriage comprises two operating levers (1, 1') of control buttons (2, 2') connected through operating steel cables (3, 4), and the operating steel cables are connected with wheels of the undercarriage. The control cable (3, 4) is equipped with a tension device (15) consisting of a body (16) closed by a plug (17), in which a sleeve (18) of a piston (19) and a cable (5) with a fixed joint (20)are inserted. The steel cable (3, 4) is further equipped with a reinforcing device (25) comprising a body (31) of the load reducing cylinder, inside which a rod (33) is arranged, isolated from the body (31) by a spring (34). In addition, the steel cable (3, 4) comprises a unit (8) fixed on the cab floor, consisting of an internal core (10) and a body (9), the steel cable (5) passing through the core of the body, the steel cable being fixed by stops on both sides of the body (9).

    本发明属于航空技术,其中液压制动系统包括直升机起落架轮子制动的双控制。直升机起落架轮子制动的控制装置包括通过操纵钢索(3,4)连接的控制按钮(2,2')的两个操纵杆(1,1'),操纵钢索与起落架的轮子连接。操纵钢索(3,4)配备张力装置(15,其由通过塞子(17)封闭的主体(16)组成,主体内插入有活塞(19)的套管(18)和带有固定接头(20)的钢索(5)。钢索(3,4)还配备加强装置(25),加强装置包括减荷缸的主体(31),主体内设有杆(33),通过弹簧(34)与主体(31)隔离。此外钢索(3,4)包括固定在驾驶舱板上的单元(8),由内部绳心(10)和主体(9)组成,钢索(5)穿过主体的绳心,钢索通过主体(9)两侧止动件固定。
