Oerlikon to Exhibit Faster Shifter for Offroad Equipment at Bauma | Construction News

Oerlikon’s Drive Systems Segment, with its brand Oerlikon Graziano, will display its latest innovative shifting solutions for commercial vehicles and
construction equipment at Bauma 2016 in Munich, Germany, April 11-17.

In commercial vehicles, loader backhoes, and telehandlers, many OEMs choose Oerlikon Graziano high-torque strut synchronizers, which reduce shifting effort and shift faster, giving drivers better vehicle control and improved productivity.

Modular by design and available in single-cone 153 or single-double
cone 168-162/170 designation, the synchronizer can be specified with a range of friction material options for optimum performance in specific applications.

The heavy-duty strut-type synchronizers can also provide an upgrade from traditional, less-efficient, pin-type units.

“Bauma 2016 is a key opportunity to showcase our technology capability to the commercial vehicle and construction industries, where our expanding range of strut-type synchronizers are already established as a popular choice for high-torque, on-highway and off-highway applications,” said Gunnar Stein,
chief technology officer of Oerlikon’s drive systems segment. “The breadth of proven benefits delivered by Oerlikon Graziano strut-type synchronizers is synonymous with our drive to improve power train durability, efficiency, and performance, and is supported by a bespoke design, validation and test service
that can reduce costs and shorten development time.”

The full design, validation and test service that the company offers to complement its heavy-duty synchronizer range has been developed to help vehicle and transmission manufacturers overcome the limited availability of resources and engineering time traditionally associated with advanced
synchronizer development. Customers using the service are able to reduce the cost of synchronizer upgrades, making a premium technology like the strut-type Oerlikon Graziano synchronizer more accessible.

A recent premium customer test program on a backhoe loader vehicle resulted in downshift synchronization four times faster from third to second gear, and more than five times faster from second to first, when compared to a previous, pin-type set-up. Gear engagement effort was also reduced by 50%, helped by a larger functioning tooth diameter (increased to Ø108mm from Ø74mm) and optimized chamfering angles. The same proportional reduction in effort was found during stationary engagement of first gear in cold conditions.

Technical highlights from Oerlikon Graziano include also the company’s patented long-life synchronizer with increased durability, a wide range of powershift clutch solutions and the servo-synchronizer concept.

Aimed at the truck and off-highway sectors, the servo-synchronizer uses self-energizing principles to deliver higher performance and lower drag torque than an equally sized double-cone system of conventional design.

Oerlikon's Bauma exhibit will be in Hall A5, Booth 149.
