Transport plays a vital role in the proper functioning of every economic system. The success of a company specializing in timber haulage depends not only on the transportation system, but also on the cooperation of all entities associated with its supply chain.
The Axle provisioned under the Drivetrain requirements of the trucks is one of the major factors of importance to have the weight distribution to be accurate and pinpoint as per the requirements. It also aims at providing the required wheel distribution characteristics to the truck at all times of operations.
In individual countries, institutions responsible for public transport and public roads have the power to limit the total weight of a truck unit (gross vehicle weight) with the simultaneous possibility of limiting permissible axle weights or increasing them in relation to those specified in EU regulations, as well as indicating the roads to be used by such vehicles.
Front shaft carries the burden of the front part of the car likewise as it facilitates steering and absorbs shocks because of paved surface variations. The front axles square measure typically dead axles, however square measure live axles in little cars of compact styles and conjointly just in case of machine drive.
Front axles can be live axles and dead axles. A live front axle contains the differential mechanism through which the engine power flows towards the front wheels. Thereby the front and Rear Axle and Shaft arrangement are of major importance to the truck operators at all times.
There is a strong correlation between pavement design standards and carrying capacity of the vehicles due to static and dynamic forces generated in the course of the movement of the vehicles. It is because of this correlation that countries prescribe maximum permissible gross vehicle weight and maximum allowable axle loads. While such norms have been laid down in India also, these are quite liberal in relation to the road pavement strength.
The currently permissible axle load is 10.2 tonnes although most of the roads have been designed for an axle load of 8.16 tonnes. It is, however, a rare trucker who adheres to the prescribed norms. Carrying one-and-a-half times the permissible load is commonplace. The rampant overloading results in extensive damage to the road network which is already under stress.
There is rare adherence to the preferred axle requirements as per the government rules of various nations of safe operations at all times. There are several possible basic vehicle wheel and axle arrangements: single wheel, dual wheel; single axle, tandem axle and tridem axle.
Their number and configuration greatly influence the dynamic loads transmitted to the road surface. It is for this reason that multiple axles can carry much greater payloads for given strength of road pavement. The Indian standards do not differentiate between a driven and non-driven or steered axle. The European standards, however, make such a distinction.
It is important to note that the equivalency relationship may vary from country to country on account of specific local conditions. Deviations from the fourth power law would significantly modify the vehicle damage factors.
The Global truck axle market can be segmented into following categories for further analysis.
It is well recognized that the use of improved vehicle technology offers great potential for reducing pavement costs related to heavy vehicle use. This brings out the need for research in various aspects of interaction between vehicle design and road surface, an area that has so far been neglected. It is well known that Indian trucks are a product of an outdated technology – two-axle rigid trucks fitted with steel leaf spring suspension.
The key issue is the interface between regulatory stability and technological change. It is often the case in India, not just in trucking but in a swathe of other areas as well, that standards have a tendency to be set in stone. The result is a sort of technological freeze. Recent trends in vehicle technology underscore the need for legislation aimed at promoting the road-friendliness of heavy vehicles.
There has been the recent integration of the Axle Lubrication management System ,which features a ring gear cover with a valve that actively regulates the oil level. This reduces the churning associated with the ring gear moving through the oil. Combined with advanced pinion bearing design reduces parasitic loss for up to a total 1.5% fuel economy improvement compared with classic Detroit axles.
Bosch showcased several future-focused powertrain concepts, including the eCity Truck diesel hybrid system for light commercial vehicles that uses an electric axle. The eAxle is a scalable, modular platform with the motor, power electronics, and transmission forming a single compact unit.
The eAxle is a compact, cost-attractive electric drive solution for battery-electric vehicles and hybrid applications. The electric motor, power electronics and transmission are combined in a compact unit directly powering the vehicle’s axle. This aids in making electric drives less complex but simpler.
Jindal Steel and Power Limited (JSPL) is the first and only Indian company to develop 60E1 1175 Heat Treated(HT) Rails for high-speed, high-axle-load applications. The Indian Railways have forecast a need for 1.8 million metric tonnes (MT) of these high-grade 60E1 1175 Heat Treated (HT) Rails per year.
Indian Railways has begun updating its track system to accommodate a 25-tonne axle weight and travel at a speed of up to 200 kilometres per hour. JSPL is devoted to producing specialty rails to meet the needs of Indian Railways and metro rail corporations, making India Atmanirbhar in rail procurement for various uses.
These rails will be utilised in dedicated freight corridors with high axel loads, such as bullet trains. Jindal Steel and Power Limited’s newly developed 60E1 1175 Heat Treated (HT) Rails have been authorised by the Research Designs and Standards Organisation (RDSO).
The Railway Board/RDSO had previously given permission for JSPL manufactured 60E1 1080 HH Rails based on inspection and testing done by the RDSO team. Metro Rail Corporations, High-Speed Corridors, and Bullet Trains are the primary users of these rails.
In terms of rail profile and chemistry, these rails are equal to European R350HT grade, however they must pass more severe Quality tests.
