Safety and lightweighting lead Gates’ priority list

The automotive industry in India is driving ahead basically with three mantras viz safety, lightweight and go-green. Gates products are underlined with all three attributes striding in parallel with the industry. The company supplies belts, tensioners, idlers, pulleys, hoses and coupling to automotive and off-road applications. It supplies these products separately or as a system based on the demand from the OEMs. These systems reduce friction, noise and improve the life. Gates caters to two-wheeler, passenger cars, CVs and offroad vehicles.

Belt systems reduce noise pollution – an indirect measure of safety for your ears, maintaining the audible limits. The transition from chain to belt allows lightweighting, reduces friction, and increases life of the vehicles. Lightweight in the Indian and global automotive segment leads to reduced CO2 emissions, facilitating the go-green initiative. This CO2 reduction gets translated to fuel economy addressing the pain point of the automotive sector. The CAFÉ norms are expected in India by the middle of 2018 which calls for fuel economy standards to be maintained based on the fleet average weight.

Gates products are basically divided into two segments: power transmission and fluid power. In power transmission, the timing belt system contributes to weight reduction by replacing the chains and metal components by belts. The average savings per vehicle could be quantified as between 400 to 600 grams. They also significantly contribute to reducing the drivetrain friction which in turn results in lower fuel consumption. Based on the specific power and torque, the same could be between three to eight per cent. Its fluid conveyance products, which can be applied in the offroad segment are designed to work at tightbend radius even at high pressures, helping designers to optimise the total length of the hoses. These hoses also contribute to safety with Gates-patented Quick-Lok couplings.

The industry is leap-frogging to BS VI underlining the deadline as 2020. Cost-optimisation should be drawn in concurrence with quality, reliability and safety. The platform design and platform-sharing facilitate the use of common parts from one engine of the vehicle family to another leading to a lot of reduction in material movement and reduced product value stream cost. The usage of timing belt, accessory belt and tensioners leads to lightweighting of the engine system. Hose products which are the prima facie required in heavy duty applications also contribute to light weight to a major extent. Significant new technology products such as hot oil belt, alternator isolator decoupler (AID) reduce parasitic losses and contribute to improved fuel efficiency leading to reduced power consumption.

Extrapolating the Paris agreement and climate change, the company’s end-customers in automotive, agriculture, heavy duty truck and off highway are actively participating to reduce the carbon foot print. Regarding the material usage Gates highlights that as a company, it is involved in using lightweight aluminium for the past 10 years in its front end accessory drive (FEAD) tensioners. For automotive applications like pulley bearing assembly, it uses extensive plastics. The plastics are highly engineered and have 70 per cent market share in India. The company is working on innovative manufacturing and design methodologies to reduce its aluminium content with lightweight thin-walled magnesium alloy castings. The reduction in weight is expected to be of 15 to 20 per cent based on the product.

Gates patented Stretch-Fit belt solutions removes the tensioner and idler from automotive applications yet provides efficient power transmission solutions with an average of 900 grams savings per FEAD system. Typically trucks would have two plane drives which cumulate to 1.8 kg of weight savings. Gates has successfully replaced the cast iron pulleys with aluminium and composite (carbon fibre) pulleys with patented technologies leading to 35 per cent weight removal. This significantly improves the drivability and they are part of the prestigious Harley and other street bikes.

Gates successfully holds the technology of hot oil belt for engine systems as a part of light weight solutions. They are already in production in the global arena. Gates plans to bring the same to Indian passenger cars, and heavy duty products as they have high strength and potential to replace gears and chains thereby reducing the weight by about 20 kg in a 400 nm torque engine. Interestingly, the hot oil belt can replace the chain system in the motor cycle segment with little to no modifications. It is a fit- and- forget type and improves the life of the engine which in turn contributes to save the environment by avoiding filling land-fills with chain scraps, discounting recycling needs.
