Simker’s rubber diaphragms for automotive brake chambers are engineered to address key performance and durability challenges through advanced material design and structural optimization:

• The corrugated groove design allows the inner and outer rubber layers to deform more evenly during operation, reducing direct wrinkling and stress concentration. This improves flexibility, minimizes damage to the diaphragm body, and enhances overall toughness.
• The embedded reinforcement layer increases the structural strength and resilience of the diaphragm, providing additional support to reduce the risk of tearing and extend service life.
• The inclusion of a metal insert prevents the push rod from acting directly on the outer rubber surface, avoiding puncture damage. An added wear-resistant layer reduces friction between the inner rubber layer and the spring, further prolonging the diaphragm’s operational lifespan.
