The invention relates to a linkage hydraulic device and a motor vehicle. The linkage hydraulic device comprises a valve body, a first spring and a second spring; a first containing cavity and a second containing cavity which are communicated through a connecting channel are formed in the valve body; a first piston is arranged in the first containing cavity, and a second piston is arranged in the second containing cavity; a first oil outlet, a first oil inlet and a second oil outlet are formed in the valve body, wherein the first oil outlet and the first oil inlet are communicated with the first containing cavity, and the second oil outlet is communicated with the second containing cavity; the first end of the first piston is provided with a first protruding shoulder, and the first piston is sleeved by the first spring; one end of the first spring is pressed on the first protruding shoulder, and the other end of the first spring is pressed on a first baffle; a second protruding shoulder is arranged at the first end of the second piston, and the second spring abuts against the second end of the second piston; and the second protruding shoulder and the wall face of the second containing cavity are in abut joint sealing or are separated. Structural hydraulic pressure can be distributed to a front brake device and a rear brake device according to a certain proportion, and a front wheel can be prevented from being clamped in advance.
