Abstract

The invention relates to a brake system of a mechanical single-drum road roller, which comprises an air storage tank (1), a brake control valve (2), a brake (3), a pressure switch (4) and a changeover governor (5) with a lock, wherein, the brake (3) comprises a cylinder (3.1) and a spring (3.2); the spring (3.2) is sheathed on a piston rod of the cylinder (3.1); the air storage tank (1) is connected with the brake control valve (2) which is connected with a rodless cavity of the cylinder (3.1) of the brake (3); the rodless cavity of the cylinder (3.1) of the brake (3) is connected with the pressure switch (4) which controls the power supply of the changeover governor (5) with a lock; and the pressure switch adopts normally open type pressure switch. The brake system of the invention utilizes an air-break brake principle to connect a pressure switch on a brake control valve or a brake cylinder, and realizes parking brake protection through controlling the changeover governor with a lock by the pressure switch. Only the parking brake is loosed, can the gear be put into gear for driving. The brake system has small operation force and safety and reliability.

Description

(1) Technical field [0001] The invention relates to a parking brake protection system of a mechanical single steel wheel road roller. It belongs to the technical field of engineering machinery. (2) Background technology [0002] The traditional mechanical single-drum roller realizes the parking brake by manipulating the brake with a flexible shaft. One of its disadvantages is that it has a large manipulation force. The most important thing is that the operator easily forgets to release the parking brake before starting the machine, which will cause the parking brake to burn out and affect the parking safety. (3) Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages, and provide a brake system of a mechanical single-drum road roller with small operating force, safety and reliability. [0004] The object of the present invention is achieved in this way: a brake system of a mechanical single drum roller, inc...
