Automotive Chassis
Consumers want lighter-weight vehicles for better fuel economy, but they don’t want to sacrifice speed or performance. This means manufacturers need to produce more powerful assemblies and equipment in smaller spaces. In addition, tightened budgets mean they have to boost their assembly-line efficiency at the same as they find new ways to add value.
NORGLIDE® Bearings and RENCOL® Tolerance Rings are becoming the components of choice for Automotive manufacturers seeking smartly designed steering systems with fewer and lighter components in place. They offer manufacturers a compact solution that reduces vibration and harshness, enhances reliability and reduces assembly time and labour, ultimately lowering costs.
Automotive Chassis Applications
The Anti-theft Steering Column uses a RENCOL® Tolerance Ring to provide overload protection to the lock collar in the case of a vehicle theft -- meets current EU legislation.
A RENCOL® Tolerance Ring is used to Mount a Bearing to the column while adjusting the NVH properties of the column.
The Collapsible Steering Column uses a RENCOL® Tolerance Ring to allow the inner tube to slip inside the outer jacket during a vehicle collision.
Video Demonstration
Saint-Gobain's RENCOL® Tolerance Rings are fitted between the outer jacket and the inner tube to ensure safe steering under normal conditions. In case of a vehicle collision, resulting high force in anxial direction, they slip and allow the steering column to collapse.
A RENCOL® Tolerance Ring is used to control the torque of the Drive Gear (acts as a simple fuse) in a column mounted Electric Power Steering System (EPSS).
NORGLIDE® Bearings are used in an electric power steering system (EPSS) where they are located inside the rolling elements. They allow the pinion shaft to slightly move in axial direction inside the roller bearings to avoid a hard stop when changing the turning direction.
A RENCOL® Tolerance Ring is used to simply mount the drive Pulley to the shaft in a rack drive Electric Power Steering (EPS) system.
A replacement of the the rack bush with a NORGLIDE® Bearing leads to improved friction and steering feel..
A RENCOL® Tolerance Ring is used to mount the Magnet Sensor to the Electric Power Steering (EPS) motor.
The Steering Height Adjustment uses a NORGLIDE® Bearing to provide a low friction surface in which column height adjustment can occur.
A NORGLIDE® Bearing is used as a liner on the inside of the Steering Yoke to give the driver a smoother feel of the steering system.
