Bendix Spicer Foundation Brake (BSFB) continues to expand its brake chamber market presence with the Bendix EverSure spring brake with No Touch technology. The New York City Department of Sanitation (DSNY) has chosen to use the EverSure spring brake when replacing the spring brakes on its collection trucks.
The Bendix EverSure spring brake is a next-generation double-diaphragm spring brake for drum brakes that offers the lightest weight in the industry while delivering best-in-class durability and performance. It is designed to industry-standard dimensions, making it easy to install as a replacement part in the aftermarket.
DSNY is the world’s largest sanitation department, collecting more than 12,000 tons of residential and institutional refuse and recyclables a day. The department’s fleet of collection trucks, which also serve as snowplows in the winter, numbers more than 2,200.
“The New York City Department of Sanitation demands superior reliability, performance, and cost-effectiveness in the components it chooses,” says Fernando Bertero, BSFB product line director for specialty. “The department is turning to Bendix for the features and benefits of the EverSure spring brake, starting with parking force, as well as the cost savings the Bendix solution offered. We are pleased to provide DSNY with a brake chamber that delivers world-class design and quality, long life, and strong return on investment.”
A key advancement in the EverSure spring brake is the elimination of contact between compressed power spring coils, allowing the protective coating to remain intact, and resulting in a significant improvement in corrosion resistance over competitive products. The spring brake is also engineered with an increased number of active coils, which further reduces surface stresses in the power spring.
“Contact between coils leads to damage, corrosion, and, ultimately, spring brake failure,” Bertero says. “The design of the power spring in the Bendix EverSure spring brake with No Touch technology avoids contact damage. Together with the additional active coils, the elimination of coil contact enables the EverSure spring brake to set the standard for durability. Corrosion resistance is especially critical to DSNY, whose trucks operate in harsh winter conditions where road salt intensifies corrosion issues in brake chambers.”
Weight optimization is another major advancement in the EverSure spring brake, which is more than two pounds lighter than competitive spring brakes. For trucks and trailers outfitted with the EverSure spring brake, key benefits of the weight reduction include the ability to carry increased payload and improved fuel efficiency. The lighter weight design helps offset the extra weight added to commercial vehicles by engine systems designed to meet recent emissions regulations. The lighter weight also leads to the best vibration resistance in the industry. Lower vibration levels help prolong the life of the spring brake and supporting components.
The new spring brake sets the standard for torque as well. BSFB optimized the diaphragm geometry of the EverSure spring brake, resulting in superior force output at both standard and long stroke lengths.
The EverSure spring brake, introduced in 2011, has undergone extensive validation tests and exceeds all compliance requirements for performance and durability in Original Equipment, as well as aftermarket.
