transport: Continuous track

Evidence: 100 • authority: 72

Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called…

The Coefficients of Friction between Rubber and Other Materials. Frictional Grip of Rubber-Tired Wheels. Abstract (i) The coefficients of friction ( ƒ I and ƒ n I ) of rubber tires on dry non-dusty surfaces are practically independent of the load on the wheel, and (with pneumatics) of the inflation pressure; on muddy surfaces the coefficients (especially ƒ n I tend to decrease with increasing load. (ii) Dust, mud, or water reduces the friction with rubber tires, but not with iron tires. (iii) The tread pattern reduces the friction on dry surfaces, but increases it on muddy surfaces. (iv) There is no systematic difference between pneumatic, semi-pneumatic (cushion) and solid tires as regarda…

In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls, cylinders, or cones) between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding. One of the earliest and best-known rolling-element bearings is a set of logs laid on the ground with a large stone block on top. As the stone is pulled, the logs roll along the ground with little sliding friction. As each log comes out the back, it is moved to the front where the block then rolls onto it. It is possible to imitat…

The Chemistry of Soft Rubber Vulcanization. IV Vulcanizing Agents Other than Sulfur. Abstract The vulcanizing action of sulfur chloride, m-dinitrobenzene, selenium, tetramethylthiuram disulfide, and benzoyl peroxide has been investigated by the use of a set of tests developed for measuring the degree of vulcanization with sulfur-cured compounds. These tests show that all of these materials are true vulcanizing agents. Comparison of the various vulcanizates with different types of unvulcanized rubber shows that the outstanding characteristic of the vulcanized structure is its resistance to flow under a wide variety of conditions. The vulcanized structure appears to be a composite one which v…

In rail transport, a derailment is a type of railway accident that occurs when a moving rail vehicle such as a train comes off its rails. Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are a potentially serious hazard. A derailment of a train can be caused by a collision with another object, operator error (such as excessive speed through a curve), mechanical failure of tracks (such as broken rails) or wheels, among other causes. In emergency situations, deliberate derailment with derails or catch points is sometimes used to prevent a more serious accident.

Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. The suspension is crucial for maintaining consistent contact between the road wheel and the road surface, as all forces exerted on the vehicle by the road or ground are transmitted through the tires' contact patches. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a…

A crane is a machine used to move materials both vertically and horizontally, utilizing a system of a boom, hoist, wire ropes or chains, and sheaves for lifting and relocating heavy objects within the swing of its boom. The device uses one or more simple machines, such as the lever and pulley, to create mechanical advantage to do its work. Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment. The first known crane machine was the shaduf, a water-lifting device that was invented in ancient Mesopotamia (modern Iraq) and then appeared in ancient Egyptian…

The effect of too stiff rail to base fastening on damage mechanism in RC ballastless track structure. Abstract This paper presents the influence of overly stiff rail fasteners, which are used to stabilize rails on a ballastless track structure, on the mechanism of the occurrence of defects in concrete baseplates. During the analysis, there was a series of field tests performed on a real track, the purpose of which was the assessment of the technical condition of the ballastless track, the assessment of concrete baseplate strength and the verification of the correctness of the rail attachment by means of a fastener. In addition, there was a series of supplementary laboratory tests performed…
