Abstract

A modular non-linear spring system capable of simulating traditional brake pedal feel when incorporated into a hydraulic and/or electro-hydraulic vehicle braking system. The system can include a first spacer having a top surface and a bottom surface and an optional second spacer having a top surface and a bottom surface. In one arrangement, a first mechanical spring is in abutting engagement with the top surface of said first spacer, a second mechanical spring is in abutting engagement with the bottom surface of said first spacer and the top surface of said second spacer, and an optional third mechanical spring is in abutting engagement with the bottom surface of said second spacer. The springs are arranged to be progressively compressed using a brake pedal of the braking system.

Abstract

A method for residual stress enhancement for a coil spring includes radially expanding at least a select axial portion of the coil spring to remove residual tensile stress from the spring inner diameter and induce residual compressive stress in the spring inner diameter. The spring is expanded by radial force on the inner diameter and/or by a helical unwinding force induced by rotating at least one end of the spring relative to the other end of the spring. A tool includes a spring expansion portion and, optionally, a diameter control portion. Cylindrical, conical and/or beehive springs are processed to enhance residual stress.

Abstract

A device for creating an angular biasing force for the roller tube of a security shade, which roller tube is mounted to a fixed structure of a vehicle. The device comprises an element attached to the fixed structure of the vehicle and a plurality of force units, each including a torsion spring exerting a biasing force between the structure and the roller tube, wherein the torsion springs each have a first inner end associated with the fixed structure and a second outer end associated with the roller tube so the torsion biasing force of each spring is in a direction from the fixed structure to the roller tube. The total angular force of the device is the sum of the biasing forces of all of the torsion spring force units when the units are connected in parallel. When connected in series, the magnitude of angular rotation is the sum of the angle of rotation of all units.
