Abstract

Systems are disclosed for the driving of a truck during a paving operation by an operator located alongside the truck and adjacent the paving site. The truck transmission power take off powers a hydraulic pump with pump output being controlled by a pair of solenoid valves with one regulating fluid flow to a hydraulic drive motor driving the truck differential through a gear reduction drive while the other valve controls fluid flow to a hydraulic motor coupled to a steering component of the truck. Both of the solenoid valves are in electrical circuit with switches located exteriorally on the truck for access by the dismounted driver as is a truck brake control. Accordingly steering, braking and fore and aft truck movement may all be accomplished by an operator positioned adjacent the truck.

Claims

1. An auxiliary power train and an auxiliary steering system for a truck to enable positioning of the truck by an operator located adjacent the truck, said auxiliary power train and auxiliary steering system comprising,

an engine,

a transmission driven by said engine, said transmission including a power take off,

a differential including an auxiliary drive shaft,

a hydraulic pump coupled to said power take off,

a first hydraulic motor,

gear reduction means coupling said first hydraulic motor to the auxiliary drive shaft of the differential,

a second hydraulic motor,

means coupling said second hydraulic motor to a steering component of the truck,

first and second solenoid actuated valve means for controlling fluid flows from said hydraulic pump to said first and second hydraulic motors for powering the truck differential and said steering component of the truck,

electrical controls in circuit with said first and second solenoid valves, said electrical controls located at a rearward location on the vehicle and accessible to an operator stationed adjacent the vehicle, and

truck brake control means located at said rearward location.

2. The auxiliary power train and auxiliary steering system claimed in claim 1 wherein said differential is alternatively driven by a truck drive shaft and said auxiliary drive shaft.

3. The auxiliary power train and steering system claimed in claim 1 wherein said truck brake control means includes an air valve in communication with a source of air pressure to operate truck brake components.
