The AB pedal linkage device double-brake trundle support comprises a support body, a bottom plate and a linkage brake assembly, the bottom plate is arranged on one side of the top end of the support body, and an axial rotating assembly is arranged between the bottom plate and the support body; the linkage braking assembly comprises a pedal A, a pedal B and a spring piece. The design of the linkage braking assembly is utilized, the pedal A, the pedal B and the spring piece are matched with one another, only different pedals in the same direction are continuously and interchangeably lifted downwards, downward pressure is applied to the pedal A during braking to achieve the braking effect, and meanwhile the pedal B moves upwards under the action of the pedal A; during unlocking, downward pressure is applied to the pedal B to achieve the unlocking effect, and meanwhile, the pedal A moves upwards under the action of the pedal B. By means of the device, braking can be effectively guaranteed; pressure is applied to a pedal A and a pedal B, so that a rotary brake point presses a wheel tread to achieve a good brake effect, and meanwhile, the front end of a spring piece is matched with a chain wheel to achieve a double-brake effect.
本发明公开了AB踏板联动装置双刹脚轮支架,包括支架、底板和联动制动组件,底板设置于支架顶端的一侧,底板与支架之间设置有轴向旋转组件;联动制动组件包括A踏板、B踏板和弹簧片。本发明利用联动制动组件的设计,通过A踏板、B踏板和弹簧片相互配合组成,只作同一方向不同踏板连续向下互换掀动,制刹时向A踏板施加向下压力达到刹车效果的同时B踏板在A踏板的作用下向上动动,解锁时向B踏板施加向下压力达到解锁效果的同时A踏板在B踏板的作用下向上动动,此装置能有效地保证刹车,是通过向AB踏板施加压力使其旋转刹车点向轮子胎面压迫达到良好刹车制动效果的同时弹簧片前端与牙盘相互契合、达到双刹效果。
