Abstract
The utility model discloses a four-wheel hydraulic braking system of an electric platform truck. The four-wheel hydraulic braking system comprises a brake master cylinder which supplies high-pressure hydraulic oil, a left front wheel hydraulic brake, a right front wheel hydraulic brake, a left back wheel hydraulic brake, a right back wheel hydraulic brake, a first hydraulic oil way and a second hydraulic oil way, wherein the left front wheel hydraulic brake, the right front wheel hydraulic brake, the left back wheel hydraulic brake and the right back wheel hydraulic brake receive the high-pressure hydraulic oil from the brake master cylinder and generate braking force, and the first hydraulic oil way and the second hydraulic oil way control the high-pressure hydraulic oil to be delivered. In the four-wheel hydraulic braking system, after a driver has the consciousness of braking and steps on a brake pedal, the hydraulic oil of the brake master cylinder is conveyed to each brake through the first hydraulic oil way and the second hydraulic oil way. The hydraulic oil can convert the strength of a muscle body of the driver into hydraulic pressure force, so that the braking force on a truck and a tractor-truck is produced, the truck and the tractor-truck can keep synchronous brake, and the phenomenon that when an existing electric platform truck brakes, the truck and the tractor-truck are prone to colliding each other because of lack of back wheel hydraulic brakes is avoided.
