Bicycle brake static pressure bench
Generation of static pressure on a hydraulic fluid to control the pressure of a bicycle disc brake system;
THE SOLUTION PROVIDED BY LF TECHNOLOGIES
Our client, Ecole Centrale de Lyon, offers training courses in line with research in the field of engineering.
Main functions
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 the low volumes of fluids moved
- silent.
Solution and Result
The proposed equipment is designed to generate a static pressure on a hydraulic fluid from an analogue setpoint supplied 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 cable for connecting the generator and fitted with a pressure gauge
- 1 output strand
- 1 control unit.
The pressure generator consists of a plunger piston driven by an electric servo cylinder linked to a pressure sensor. The pressure is regulated by the movement of the plunger piston, which compresses the fluid in a chamber.
The control unit is remote on a console; The control interface, custom-developed by our programmers, displays actual and set pressure in real time.
Products tested
Bike 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 brake pads. The hydraulic control compresses the pads, which rub against each side of the disc.
