Tested product
Bicycle disc brake
The disc brake is a braking system for vehicles with wheels in contact with the ground. The system uses a disc attached to the wheel hub and pads. The hydraulic control compresses the brake pads, which are rubbed on each side of the disc.
Objective
Automatic pressure control of a hydraulic disc brake as part of a vibro-acoustic research test bench.
Problematic issues
The proposed equipment must be :
- compatible with the mineral fluid used
- compatible with small volumes of displaced fluids
- silent.
Solution and result
The proposed equipment is designed to generate a static pressure, on a hydraulic fluid, from an analog set point delivered by the customer, in order to control the pressure of a disc brake system on a test bench.
The equipment consists of:
- 1 static pressure generator
- 1 central strand to connect the generator and equipped with pressure measurement
- 1 output strand
- 1 steering unit.
The pressure generator consists of a plunger piston driven by an electric servo cylinder associated with a pressure sensor. The pressure is regulated by the movement of the plunger which compresses the fluid in a chamber.
The control unit is located on a control panel. The control interface, developed to measure by our programmers, offers a real-time display of the actual pressure and the set pressure.
