There is more pressure than ever on heavy-truck engineers to find and create significant improvements in fuel economy and reduce tailpipe greenhouse gas emissions. Aerodynamic opportunities exist with technologies such as active grille shutters and truck platooning—and simulation will help to optimize these designs.
Semi-solid casting is a near-net shape casting process that is capable of producing extremely high-quality castings. It differs from all other casting processes as it does not use fully liquid metal to produce the castings, instead using a feed material that is preferably about 50% solid and 50% liquid.
The challenges for the off-highway industrial engine supplier goes beyond simply meeting ever more stringent emissions regulations in Europe. Their engine designs also need to minimize total cost of ownership while delivering power and fuel efficiency in a worldwide market.
New PL72, PL83, and PL87 pipelayers feature differential steering and an electronically controlled hydraulic system that places total control of lifting functions into a single joystick. A dash-mounted LCD display provides onboard diagnostic information for the operator.
The PD400 has a common electronic control architecture that supports the full suite of JDES advanced motor control software to optimize performance of permanent magnet or induction motors in hybrid electric applications.
The company is looking at adjacent markets for its large video screens and sees the truck industry as a potential opportunity. The Safety Truck prototype was developed with the aim of improving road safety.
Off-highway machine mounting systems, especially the cab mounting system, significantly affect the operator comfort in the cab by providing enough damping for a good ride and isolating the structure-borne forces from traveling into the cab.
Benefiting from Poclain Hydraulics’ know-how in turret rotation solutions, the new range of MZ motors are more “concentrated” for integration into machines like mini and medium-sized excavators, where space for hydraulic features is limited.
