The invention relates to the technical field of environment-friendly travel, and discloses a bicycle front and rear wheel cooperative brake device which comprises a wheel carrier. A wheel shaft movably sleeves the bottom of the wheel carrier, an auxiliary brake wheel fixedly sleeves the outer surface of the wheel shaft, a contact turntable is fixedly mounted at one end of the wheel shaft, and fourfixed connecting blocks are fixedly mounted at one side of the wheel carrier; and a trigger device is fixedly mounted at one end of each of the four fixed connecting blocks, a stroke pipe, a hydraulic pipe and a brake sleeve are filled with hydraulic oil, and the pipe diameter of the stroke pipe is larger than that of the hydraulic pipe. Therefore, the hydraulic oil in the stroke pipe encountershuge resistance in the process of flowing into the hydraulic pipe, and the resistance acts on the contact turntable through a sliding device and enables the auxiliary brake wheel to decelerate, so that forward toppling caused by overlarge center-of-gravity shift of a driver due to the fact that wheels are directly locked by an original brake device in the braking process is avoided, and the safetyperformance of the device in the braking process is improved.

    本发明涉及环保出行技术领域,且公开了一种自行车前后轮协同刹车装置,包括轮架,轮架的底部活动套接有轮轴,轮轴的外表面固定套接有副刹车轮,轮轴的一端固定安装有接触转盘,轮架的一侧固定安装有固定连接块,固定连接块的数量为四个且固定连接块的一端固定安装有触发装置,通过行程管,液压管和刹车套筒的内部充满液压油并且行程管的管径大于液压管的管径。从而使得行程管中的液压油流入到液压管中的过程中会遇到巨大的阻力,在该阻力会通过滑动装置作用于接触转盘并使得副刹车轮进行减速,从而避免了原有刹车装置在刹车过程中直接将车轮抱死而导致驾驶者重心偏移过大而导致向前倾倒,提高了该装置在刹车时的安全性能。
