| The hybrid vehicle kit comprises a vehicle body capable of being interchangeably coupled to either one of a wheel kit thus forming a hybrid vehicle in a wheel mode, the wheel kit having a number of ground-engaging wheels; and a track kit, thus forming the hybrid vehicle in a track mode, the track kit having a pair of ground-engaging tracks carried by track wheels. The vehicle has a pair of powered driving hydraulic pumps and a number of wheel drives powered by a corresponding one of the driving hydraulic pumps. In the wheel mode the ground-engaging wheels are operatively mounted to corresponding wheel drives and an electronic circuit calculates hydraulic rate data on the basis of speed data to control the first and second driving hydraulic pumps so that they will administer a hydraulic rate to the wheel drives which is representative of the hydraulic rate data to control the rotational speed of the ground-engaging wheels which will propel the hybrid vehicle. In the track mode at least some of the track wheels are operatively mounted to corresponding wheel drives and the electronic circuit calculates hydraulic rate data on the basis of the speed data and of the steering data to control the first and second driving hydraulic pumps so that they will administer a respective hydraulic rate to the wheel drives which is representative of the hydraulic rate data to control the rotational speed of the at least some of the track wheels that are operatively mounted to corresponding wheel drives, to both propel and steer the hybrid vehicle. | ||||||

A traveling device for crawler type heavy equipment is provided, which can improve the manipulability by preventing an abrupt decrease/increase of a traveling speed of the equipment when a combined operation, in which a left/right traveling device and a working device are simultaneously driven, is performed. The traveling device for crawler type heavy equipment includes first and second variable displacement hydraulic pumps (1,2), switching valves (5,6,7,8)(10,11,12) for left and right traveling motors and working devices, a straight traveling valve (13) shifted to supply hydraulic fluid to the switching valves for the left and right traveling motors and to the switching valves for the working devices in response to a signal pressure in a combined working mode, a variable orifice shifted to intercept the supply of the hydraulic fluid toward the traveling device in response to the signal pressure in the combined working mode if a load pressure of the working device is relatively higher than that of the traveling device, a mode selection device for selecting a working mode, and a controller for outputting control signals to electro proportional valves and to electric control valves so as to control discharged flow rates of the first and second hydraulic pumps in accordance with the selected working mode.

| A propulsion system is for a road milling machine with a rotatable cutter drum (3). The system includes four crawler assemblies (12) movably coupled with the mainframe so as to define front and rear, and left and right, pairs of crawler assemblies. Four steering actuators (14) are each coupled with a separate crawler assembly and each angularly displaces the crawler about a vertical axis (12a). A first pump (16A) is fluidly coupled with the left pair of crawlers and a second pump (16B) is fluidly coupled with the right pair of crawlers. A control (20) is configured to selectively operate the four actuators in a plurality of different steering modes, one steering mode being a circle steer mode, and to operate the two pumps such that one of the left and right pairs of crawlers are drivable by the first pump in one direction while the other pair of crawlers are drivable in an opposing direction. | ||||||

| The powered hybrid vehicle is capable of being operative in either one of first and second distinct driving modes each comprising corresponding first and second directional systems. The hybrid vehicle has a control shaft operatively coupled to a steering device, a first steering member operatively coupled to the first directional system, a second steering member operatively coupled to the second directional system and a shaft coupler capable of selectively coupling the control shaft to either one of the first and second steering members. The hybrid vehicle may be steered by controlling the steering device notwithstanding which one of the first and second driving mode it is in. | ||||||
