HYDRO ELASTIC SUSPENSION SYSTEM

The main component of the hydraulic suspension is the displacer unit, which is attached to the individual wheels of the vehicle. The displacer unit consists of two chambers. Chamber A is just above the flexible diaphragm and the other B is above the separating member and connected by the other displacers by a hose pipe. The stem is usually connected to the lower link of the double wishbone. 

The diaphragm is connected with the piston and bears the wheel load. The fluid in chamber A can all the time pass into the chamber B through the bleed holes provided in the separating member. When the pressure of liquid in B rises sufficiently above that in A, then the rubber flap valve which is loaded by the spring will open downwards thus allowing the fluid to pass from B to A through the holes. Similarly to pass the fluid from A to B the damper valve functions accordingly. The fluid in B acts on the under side of the rubber element and through the   hose pipe is transmitted to the other wheel unit. The Canister Displacer unit in Hydraulic suspension is provided at the outside of the rubber element, while the pot member at inside. The canister is fixed to the body structure of the vehicle.
