摘要： A track-type vehicle comprising novel means for obtaining propulsion, superior maneuverability and improved riding characteristics through four individually-driven sprocket wheels providing power for its track chain assembly. The vehicle is powered by two engines transversely mounted at either end of the vehicle. By controlling the speed and direction of each track chain assembly independently of the other, various turning radii are possible, ranging from a quick pivot to a gradual curve. Each track chain assembly is supported by a plurality of pivotal bogie wheel assemblies. The bogies move in a reciprocal manner and are pivoted at the point of attachment to the vehicle and at the wheel assembly itself. The track chain assembly is automatically adjusted to a suitable tension for a smooth ride and a long wear life of the chain assembly.

摘要： Disclosed is a heavy duty retractable traction intensifyer for adding utility and maximizing performance of agricultural tractors, harvesting combines and the like. The device has a series of aggressive and thin spades, which in fields slice into stronger subsurface layer of soil, thereby increasing drawbar pull and decreasing wheel slip and soil compaction. The series of spades is arranged in groups, each secured to a length of sturdy wire rope which is threaded through a series of tubes, whereby each group can be rotated and thus expeditiously retracted for driving on roads. The series of tubes is the outermost portion of a flexible frame, bolted to an accompanying powered tire-wheel assembly via a spacer. For obtaining a comfortable ride during heavy pulling in fields said frame includes a series of resilient semicircle-shaped loops, formed from flat stock of high-strength spring-like steel, extending radially outward from a circular band forming the innermost portion thereof. For assuring satisfactory durability and reliability of the device said frame further includes various devices for keeping magnitude of flexing within safe limits and a spade-lock. The application of wire rope is as unique as it is useful. Not only does it provide a simple way of securing and supporting the series of spades but its inherent capacity for flexing is here fully utilized, resulting in the feature of ultra-quick conversion from "rubber-drive" for roads to "steel-drive" for fields and vice versa.

摘要： There is disclosed a traction enhancing device for a wheeled agricultural tractor, in which a flexible frame comprises a circular band, to which are welded a series of spade holders. The frame is bolted to the rim of the wheel by spacers, so that the frame is in non-contacting relationship with the tire. The spade holders are fabricated from flat stock of high strength spring-like steel, formed into a semicircles, and have outer tubular anchors. These anchors encircle a plurality of wire ropes that lie in mutual end-to-end relationship and described a circle that is concentric with the wheel. A series of spade assemblies are rigidly fastened on the wire ropes. The wire ropes are preloaded, and can be rotated within the anchors so that the spades assemblies alternate between a ground-engaging position and a ground-avoiding position. The spades each include lugs that slice into the strong subsurface layers of the soil, and provide a significant degree of traction improvement as the wheel turns. The flexible frame and spades follow the tire's contour, thereby forming its own elongated footprint as the wheel turns. As there is no contact between the frame and tire, riding comfort is not adversely affected even at heavy pull on a dry soil surface. Under the influence of vertical load and drawbar pull the device deforms as the spades penetrate into the soil. The dimensions of the spade holders and their spring-like elasticity allows structural compression to repeatedly occur without permanent deformation.

摘要： A vehicle traction device for passenger cars and alike including a flexible belt-like traction mat with transverse corrugations on one side and substantially smooth on the other side. One end of the mat is pivotally secured to anchoring means including a flexible anchoring pad and ground gripping element.In use, the traction mat is first arranged to form a loop relative to the anchoring means. With its corrugations facing a tire and its smooth side facing the ground the traction mat will easily be drawn under a spinning wheel until that end of it, which is secured to the anchoring means becomes choked by the anchoring means. The tractive effort then developed causes the anchoring means to become wedged and thus assuring its fixed position, whereby the traction mat is prevented from being propelled away by the driven wheel.
