FIELD: transportation.
SUBSTANCE: invention relates to hybrid automobiles. Automobile with a hybrid drive comprises a wheel, driven by an electric machine, a device of braking energy recuperation, a braking system with a pedal, the main braking cylinder and the wheel brake, a reduction valve unit, which lowers braking pressure at the recuperation stage, and a compensator of hydraulic effect of the reduction valve device. Also there is an additional main braking cylinder comprising pistons paired to each other by means of the first connecting element, and the main braking cylinder is divided into three chambers. The first and second chambers are hydraulic, and the third one comprises a compensating element and is made in the form of a compensator with the discharge function. The first piston comprises a through hole for hydraulic connection of the first chamber with the second chamber. The first piston in the direction opposite to the braking direction, is paired by means of the second connecting element with the piston of the reduction valve device hydraulic drive and is made with the possibility of closing. There is a stop for the first or second piston. The main braking cylinder also performs the function of the pressure regulation unit. The braking system is regulated at the recuperation stage.
EFFECT: invention improvement.
