Abstract

1394936 Endless track vehicles CMI CORP 30 Jan 1973 [14 Feb 1972] 4514/73 Heading B7H [Also in Division E1] Road construction apparatus 10 comprises a main frame 12, rear drive means 22 for moving the apparatus and a front track assembly 24 for steering the apparatus, and a steering assembly 30, Fig. 4, including an arm 88 connected to the front track assembly, a cylinder 90 connected to the frame 12 and the arm 88 for moving the arm, and means 96 for confining the movement of a portion of the arm near its connection with the cylinder to a generally horizontal plane. The front track assembly 24 is mounted on a forward extension 80 of the main frame and the cylinder 90 is actuated to steer the apparatus in response to signals from a track steering sensor 52, Fig. 5, which follows a reference such as a string line and is carried by an arm slidable in a housing 160 on the main frame. A rod 116 carried by the front track assembly is movable in an arcuate guide 118 to provide feedback to the sensor 52 by means of push-pull cable 124. The main frame may be raised or lowered relative to the front track assembly by a front positioning assembly 76, which is controlled in response to signals from an elevation sensor 54 carried by an arm 183 which is slidably movable by means of a handwheel 178 in a housing 166 secured to the arm 158. The arm 88 is pivotally connected to the front track assembly about a horizontal axis 94 so that the steering and elevation controls are independent. Pointers 138, 150 indicate the steering and elevation positions respectively of the front track assembly. The rear drive means comprises left and right endless tracks 62, (64) whose elevations with respect to the main frame 12 are controlled by positioning assemblies 72, (74) each of which may be controlled by a switch (422) or (423), Fig. 15 (not shown) or may be connected to a positioning switch (420) which produces a signal indicative of the deviation of the cross slope of the apparatus from a selected level. The road construction apparatus includes an auger 36 with a double helical flight of cutter blades shaped to excavate earth and move it towards the centre where it is guided by a baffle (212), Fig. 13 (not shown) through an opening (210) in a mouldboard 38 on to a base conveyer 42 mounted beneath the frame 12 and thence through a funnel 280 on to an elevated conveyer 44 which is pivotally mounted on the rear of the main frame at supports 228, 230 and may be swung through 180 degrees by hydraulic actuators (252), (254), Fig. 7 (not shown). The mouldboard may have side extension wings (302), (304) raised and lowered by actuators (320).
