The function of the brake wheel cylinder is to convert the hydraulic energy input from the brake master cylinder into mechanical energy to make the brake enter the working state. There are two types of brake wheel cylinders: single piston and double piston. Single-piston brake wheel cylinders are mainly used for double-collar shoe and double-slave shoe brakes, while double-piston brake wheel cylinders are widely used, which can be used for lead-slave shoe brakes, and can be used for two-way double-collar Shoe brakes and two-way self-increasing brakes.

Basic structure

Single piston brake wheel cylinder
As shown in the figure for a car double collar shoe front brake with a single piston brake wheel cylinder. The sealing element of the liquid chamber adopts the sealing ring 4 installed in the groove of the piston guide surface. The oil inlet clearance is maintained by the boss on the end face of the piston.

Double piston brake wheel cylinder
As shown in the figure is a double piston brake wheel cylinder.
The cylinder block 1 is bolted to the brake backing plate. There are two pistons 2 in the cylinder, and the inner cavity between the two pistons is sealed by two cups 3. When braking, the brake fluid enters from the oil pipe joint and the oil inlet hole 7, the piston moves outward under the action of hydraulic pressure, and the brake shoe is pushed to open through the top block 5. The spring 4 ensures the close contact of the cup, the piston and the brake shoe, and maintains the oil inlet gap between the two pistons.
