The embodiment of the invention provides a linkage hydraulic valve and a braking hydraulic system, and relates to the technical field of hydraulic braking. The linkage hydraulic valve comprises a valve body, a first valve element assembly and a second valve element assembly. The valve body is provided with a first hydraulic cavity and a second hydraulic cavity, meanwhile, the valve body is furtherprovided with a first hand brake inlet, a first foot brake inlet and a front brake outlet which are all communicated with the first hydraulic cavity, the first hand brake inlet and the first foot brake inlet are respectively used for outputting brake fluid from the front brake outlet, and therefore the front brake braking is achieved. The valve body is further provided with a second hand brake inlet, a second foot brake inlet and a rear brake outlet which are communicated with the second hydraulic cavity, and the second hand brake inlet and the second foot brake inlet are used for enabling brake fluid to be output from the rear brake outlet, so that rear brake braking is achieved. A foot brake is communicated with the first foot brake inlet and the second foot brake inlet at the same time, when the foot brake is stepped, front-back braking can be achieved at the same time, the front-back braking linkage effect is achieved, and therefore the braking effect is improved.
本发明的实施例提供了一种联动液压阀及制动液压系统,涉及液压制动技术领域。本发明的实施例提供的联动液压阀包括阀体、第一阀芯组件和第二阀芯组件。阀体具有第一液压腔和第二液压腔,同时阀体上还设置有均与第一液压腔连通的第一手刹入口、第一脚刹入口和前刹出口,第一手刹入口和第一脚刹入口分别用于使制动液从前刹出口输出,从而实现前刹制动。阀体上还设置有与第二液压腔连通的第二手刹入口、第二脚刹入口和后刹出口,且第二手刹入口和第二脚刹入口分别用于使制动液从后刹出口输出,实现后刹制动。将脚刹同时与第一脚刹入口和第二脚刹入口连通,当踩动脚刹时即可同时实现前后刹制动,达到前后刹联动的效果,从而提高制动效果。
