brake chamber , Iran

A single-circuit brake booster consists of a drawn steel main housing with a thickness of 1.5 mm. The diaphragm diameter typically ranges from 200 to 250 mm in passenger vehicles. This system provides a force multiplication ratio boost ratio between 3:1 and 5:1. The vacuum pressure generated by the engine exceeds 0.8 bar absolute. The control valve is made from engineering polymers with heat resistance up to 120°C. The output pushrod uses carbon steel with an anti-corrosion coating. The main valve seat is machined with a dimensional tolerance of ±0.05 mm. The assembly is tested for over 500,000 operational cycles.

The internal structure features a synthetic rubber diaphragm resistant to oil and ozone. This diaphragm separates the chamber into vacuum and atmospheric sections. The piston rods linear travel is a maximum of 40 mm. The system includes a non-return one-way valve with a leakage tolerance below 1 cm³ per minute. System response time to driver input is less than 100 milliseconds. A fail-safe mechanical linkage directly transfers pedal force in case of failure. The total assembly weight typically ranges from 2.5 to 4.5 kg. This design complies with FMVSS 135 and ECE R13 safety standards.You can order and buy brake chamber from Iran by contacting us through whatsaap and email.
