The invention discloses a disc and drum brake linkage structure which comprises a front wheel, a rear wheel and a frame and further comprises a front wheel brake handle, a rear wheel brake handle, a disc and drum brake connector, a disc brake oil distribution pump, a front wheel disc, a front wheel disc brake pump, a rear wheel drum brake, a front wheel oil inlet pipe, a front wheel oil outlet pipe and a rear wheel brake cable. An oil distribution cavity is formed in the disc brake oil distribution pump, an oil distribution push rod and an oil distribution spring are arranged in the oil distribution cavity, and the oil distribution cavity comprises a main cavity and a branch cavity. The rear wheel brake handle controls braking of the front wheel and braking of the rear wheel at the same time through the disc-drum brake connector, and the work needed by braking of the front wheel and provided by the rear wheel brake handle is larger than the work needed by a rear wheel drum brake through cooperation of an oil distribution push rod in a disc brake oil distribution pump and a spring. The oil distribution push rod isolates oil in the branch cavities and the main cavity, so that when a rear wheel brake handle applies pressure, the oil distribution push rod can be pushed to extrude the oil in the main cavity, the oil is converged into the front wheel oil inlet to the front wheel disc brake pump, and braking is completed.
本发明公开了一种碟鼓刹联动结构,包括前轮、后轮、车架,还包括前轮刹车把、后轮刹车把、碟鼓刹连接器、碟刹分油泵、前轮碟盘、前轮碟刹泵、后轮鼓刹、前轮进油管、前轮出油管、后轮刹车线,碟刹分油泵设置有前刹进油口、后刹进油口、前轮进油口,碟刹分油泵内置有分油腔,分油腔内置有分油推杆、分油弹簧,分油腔包括总腔和分腔。后轮刹车把借助碟鼓刹连接器同时控制前轮和后轮的制动,并且通过碟刹分油泵内的分油推杆与弹簧的配合使得前轮制动所需要的后轮刹车把所提供的功大于后轮鼓刹所需的功。分油推杆隔绝分腔与总腔内的油液,使得后轮刹车把施压时可以推动分油推杆挤压总腔内的油液使其汇入前轮进油口至前轮碟刹泵,从而完成制动。
