A revolutionary introduction to the heavy vehicle industry is expected to happen very soon when power split transmission comes into play. This kind of final drive mechanism is to be used as standard for a new series of large wheel loaders. Reputed construction machine manufacturers are in the final stages of testing this transmission at customer sites and test sites to check for effectiveness and compatibility and the good news is that this transmission is gradually proving to be durable and highly efficient.

After hours of testing and trying this new mechanism, manufacturers have a lot of positive reports to offer. The success of this transmission in wheel loaders will be the next big thing as per industry standards.

What are the reported advantages of using this transmission?

The construction industry is demanding equipment that boost fuel efficiency to be able to compensate for rising costs. The power split drive train will boost fuel efficiency by a whopping 30% as compared to traditional drive loaders. This will be an incredible find and is bound to take the construction industry by storm.

What more is in store for wheel loaders? The power split drive train brings together hydrostatic as well as mechanical drive and makes use of a constantly variable transmission gear box to ensure automatic adjustment between the two drives, thus helping the final drive to match the job at hand.

Here, the hydrostatic and mechanical drives serve two different purposes respectively: the hydrostatic transmission is perfect for short loading cycles. The mechanical transmission, on the other hand, is mostly used for long distances and while driving uphill.

The reason why most manufacturers are looking forward to the power-split transmission is the fact that this mechanism combines the advantages of both hydrostatic and mechanical drives. It is not for nothing that the transmission is being labelled as ‘futuristic’.

On being tested, this transmission has also proven to reduce internal stress, thus increasing component life. Manufacturers are of the opinion that a customer wants an enhanced lifespan of the loaders and this is exactly what the power split transmission mechanism will do.

New entries are accompanied by additional costs but what do we have here?

Construction companies are already dealing with additional costs to help maintain pollution standards and tons of other regulations. A new mechanism would only add to the costs but that is not always true. With the power split transmission being standard, it would not lead to additional costs for the company. There might just be a 1% hike in inflation adjusted pricing when the mass production of these power loaders start.

Has this been tested to meet safety standards?

The new large wheel loaders with the power-split transmission have been tested for efficiency and durability at customer sites, sawmills and recycling companies. Manufacturers can have a sigh of relief to know that there has been no reported component failure and both the power-split transmission and its larger axles have surpassed durability expectations.

The Bottomline

Power-split transmission is being heralded as the future of final drives and the proof is in the pudding. Its cost effectiveness, fuel enhancing feature and automatic switching of transmissions as per the job on board makes it a phenomenon to look forward to.
