View page
US Patent:
40649679, Dec 27, 1977
Filed:
Jul 23, 1976
Appl. No.:
5/707961
Inventors:
Mac R. Doolittle - Charlotte MI
Assignee:
Clark Equipment Company - Buchanan MI
International Classification:
B62D 510
B62D 710
US Classification:
180155
Abstract:
A steering mechanism for use in a vehicle, such as an industrial truck or the like, in which a two-way power steering actuator cylinder having a piston rod extending from both ends is supported from and above a steering axle by pivot tube and pivot shaft members which enable universal movement of the steering cylinder, the piston rod functioning also as a tie rod which is connected at each opposite end to a modified four-bar steering linkage which is in turn connected to a dirigible wheel. King post assemblies are secured to opposite ends of the steer axle which connect the four-bar linkages to the wheels. Each such linkage includes a steering link extended in length to connect the adjacent end of the actuator piston rod. One end of a guide link of the four-bar linkage is connected to the steering link intermediate the ends thereof.
