The invention relates to the field of vehicle braking systems, and discloses a double-linkage delay proportional valve and a braking system thereof.The double-linkage delay proportional valve comprises a proportional valve body and a pressure buildup valve element, a partition wall is arranged in the proportional valve body, and the interior of the proportional valve body is divided by the partition wall into two closed valve cavities which are arranged up and down; the pressure buildup valve element is arranged in the valve cavities in a sliding mode, one valve cavity is divided into a main cavity I and an auxiliary cavity I through the pressure buildup valve element I, and the other valve cavity is divided into a main cavity II and an auxiliary cavity II through the pressure buildup valve element II. The isolation wall is provided with an oil way channel I and an oil way channel II which penetrate through the isolation wall, the main cavity I and the auxiliary cavity II are communicated through the oil way channel I to form a front brake oil way, and the auxiliary cavity I and the main cavity II are communicated through the oil way channel II to form a rear brake oil way; according to the linkage device, when a motorcycle or an electric vehicle operates any one of a brake pedal or a brake hand brake of a front brake and a rear brake of the vehicle, the linkage device can act on the rear wheel brake and the front wheel brake at the same time, and a driver can operate the linkage device with one hand or one foot conveniently.
本发明涉及车辆制动系统领域,公开一种双联动延迟比例阀及其制动系统,包括比例阀本体、建压阀芯,比例阀本体内设置有隔离壁,隔离壁将比例阀本体内分隔形成上下分设的两个密闭的阀腔;建压阀芯滑设于阀腔内,其中一个阀腔由建压阀芯Ⅰ分隔成主腔室Ⅰ和副腔室Ⅰ,另一个阀腔由建压阀芯Ⅱ分隔成主腔室Ⅱ和副腔室Ⅱ;隔离壁上设置有贯通隔离壁的油路通道Ⅰ和油路通道Ⅱ,主腔室Ⅰ与副腔室Ⅱ通过油路通道Ⅰ连通构成前刹油路,副腔室Ⅰ与主腔室Ⅱ通过油路通道Ⅱ连通构成后刹油路;本发明提供在摩托车或者电动车无论在操作在车辆前、后刹的制动踏板或制动手刹车中的任意一个时,同时作用后轮制动也可作用于前轮制动的联动装置,方便驾驶人员单手或单脚操作。
