Oct 1, 2002

Appl. No.:

10/262730

Inventors:

Suat Ali Ozsoylu - Saginaw MI
William F Feriend - Freeland MI
Michael R. Pyrett - Flint MI

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B62D 504

US Classification:

180443

Abstract:

A steering system for a vehicle, the steering system includes a rack-independent actuator. The rack-independent actuator has component parts isolates from undesirable loads by two universal joints that isolate mechanical components of the actuator from transient loads that may be encountered by the rack or rack housing.

International Classification:

B62D 5/04

US Classification:

180444, 64 8923, 64 8936

Abstract:

A steering system for a vehicle may include a load displacement system allowing transient loads of the steering mechanism to be displaced. The steering system may also include a first coupling mechanism coupling an electric motor to a rack housing, and a second coupling mechanism coupling a ball nut to a rack. A method for providing an actuation force to a rack of a vehicle includes isolating non-axial loads from an electric motor of a steering system and isolating non-axial loads from a linearly actuatable member of a rotary-to-linear conversion device in the steering system. An actuator for a steering system may include a rotary to linear actuator, a movable linear section, and an interface between the rotary to linear actuator and the linear section. The interface may include one or more cylindrical joints, revolute joints, compliant members, or a block on a plane wherein the total degrees of freedom for the system including the rotary to linear actuator, rack, and interface may be one, while the interface may be limited to three degrees of freedom.

International Classification:

F16H 57/12

US Classification:

74409, 74440, 74443

Abstract:

A gear arrangement includes a first section having a first plurality of teeth and at least a portion of the first section is made of a compliant material. There is also a second section having a second plurality of teeth. The second section is made of a stiff material. The first section is arranged axially adjacent to the second section and each of the first plurality of teeth has a tooth flank that changes axially across the tooth flank. A method for manufacturing a gear arrangement includes fabricating a first gear, which includes a first plurality of teeth, and a bearing from a compliant material. The method also includes mounting a second gear, which includes a second plurality of teeth, to the bearing, aligning the first plurality of teeth with the second plurality of teeth, and coupling the first gear with the second gear.

International Classification:

B62D 1/184
B62D 1/187
B62D 1/189

US Classification:

74493, 280775

Abstract:

A steering column assembly includes a mounting bracket and a column jacket moveable relative to the mounting bracket to adjust a position of the column jacket. A rake plate is pivotably coupled to the mounting bracket and defines a rake slot having rake slot teeth. A telescope plate is pivotably coupled to the column jacket and defines a telescope slot having telescope slot teeth. A rake lock having rake lock teeth is disposed within the rake slot and a telescope lock having telescope lock teeth is disposed within the telescope slot. The rake plate and the telescope plate pivot as the rake lock and the telescope lock move into interlocking toothed engagement to avoid peak-to-peak contact between the lock teeth and the slot teeth, thereby permitting full meshing engagement between the lock teeth and the slot teeth.
