A hydraulic accumulator originally developed for the automotive industry is opening up new possibilities for agricultural machinery operating under extreme conditions. Freudenberg Sealing Technologies (FST) has successfully transferred proven passenger car technology to a demanding new application.<\/strong><\/strong><\/p>\n\n\n\n

For years, Freudenberg Sealing Technologies (FST) sold piston accumulators for automotive applications. When this chapter closed, the door opened to a new opportunity. Mauro Lasagno, Global Key Account Manager for Mobile Machinery, recognized that the technology still had strong potential – just not in its original application. Through his close ties to the agricultural machinery industry, Lasagno learned that CNH Industrial N.V. was facing challenges with the hydraulic systems used in its agricultural equipment. The tractors used for the production of sugar cane, in particular, operate under extreme conditions and place high demands on component durability and temperature resistance.<\/p>\n\n\n\n

At the time, CNH relied on diaphragm accumulators, which were failing after only about half of their intended service life. The challenge was compounded by the installation situation: the accumulators are mounted direct at the transmission and can only be accessed with significant effort. \u201cThis would require dismantling larger parts of the drive train. That costs time and money, so the requirements for service life have to be correspondingly high,\u201d explains Jens Wolfram, Global Segment Director Mobile Machinery \u2013 Agriculture.<\/p>\n\n\n\n

The operating environment made matters even more demanding. In Brazil, where many of these machines are used, high temperatures, extreme humidity, and continuous operation are the norm. Under these conditions, standard diaphragm accumulators proved unsuitable. Lasagno proposed a different approach: testing FST piston accumulators that had been used successfully for years in millions of passenger car transmissions.<\/p>\n\n\n\n

The accumulators produced at FST\u2019s Lead Center Accumulators in Remagen met the customer\u2019s expectations. A 0.75\u2011liter piston accumulator proved to be a good fit for agricultural applications and was mounted directly on the transmission. Initially, FST supplied the accumulators as spare parts, with an adapter developed by the customer. Today, that intermediate solution is no longer necessary.<\/p>\n\n\n\n

Comparative testing delivered clear results. The FST piston accumulator achieved a service life three to four times longer than the diaphragm accumulator previously in use. By building on proven passenger car technology and adapting it flexibly, FST was also able to provide test samples to CNH within a very short timeframe. \u201cWe were able to convince CNH – and now supply the accumulator in series production,\u201d Wolfram says.<\/p>\n\n\n\n

The successful transfer of technology has sent a strong signal beyond this single application. FST is now examining whether the concept can be extended to other customers and transmission systems. \u201cFor us, this is a special success story,\u201d Wolfram adds. \u201cA component originally developed for passenger cars is finding its way into agricultural machinery – with virtually no technical modifications.\u201d<\/p>\n\n\n\n
