Agricultural vehicle chassis frame - narrows in centre to allow front wheels to turn further to provide smaller turning circle while using four equal sized wheels

摘要

The agricultural vehicle consists of an engine (1) connected by a pair of lateral girders (2) to a gear box which is driven by a drive shaft (6). The lateral girders (2) are bent inwards so that when the front wheels (5) are turned the extra angle allowed enables a tighter turning circle. The wheels (5,12) are held below the frame members (15) so that the ground clearance is about 60 to 80 per cent of the wheel depth, while the wheel dia. is about 60 to 40 per cent of the track width. This method provides a vehicle which has a narrow track width yet small turning circle required for use in fields.
