US Patent:
40434222, Aug 23, 1977
Filed:
Nov 19, 1976
Appl. No.:
5/743394
Inventors:
John C. Barrett - Rogers MN
Gerald T. Gfroerer - New Hope MN
Assignee:
Raygo, Inc. - Minneapolis MN
International Classification:
B62D 508
US Classification:
180140
Abstract:
An electro-hydraulic steering system for vehicles such as roller type surface compacting machines which have a steerable ground-engaging unit at each end of the chassis. The system combines a conventional orbital type steering valve, two conventional solenoid actuated hydraulic valves and two conventional lock valves with an electric control circuit that includes simple console-mounted selector switches, a foot pedal-controlled switch and a simple cam-actuated switch that is automatically actuated in consequence of shifting the control lever of the vehicle's transmission from "forward" to "reverse" and vice versa, in a manner which gives the operator unprecedented flexibility in his choice of steering mode.
