ALLISON TRANSMISSION
New Products

Allison has introduced a new twin-countershaft automatic transmission for heavy-duty tractors used in over-the-road applications. More information on the TC10 transmission can be found elsewhere in this issue.

New Technology

Allison said it has added a new optional provision for a ground-driven pump to its 4000 Series transmission to ease the installation of emergency steering systems that are a requirement for most European 8x4 dump trucks. Allison now also offers a second “deep reverse” gear in addition to the standard reverse gear, exclusively available on 4700 and 4800 Series seven-speed models. The additional gear provides greater control and engine braking during operation on steep grades and for increased maneuverability when operating in confined spaces, Allison said.

The 5620 and 6620 commercial transmissions have been recently introduced to respond to changes in engine characteristics that are increasingly prevalent in the construction sector. Greater use of digital control for engines delivers sharper torque response through the driveline, necessitating upgrades to protect the drivetrain. The lock-up clutch, turbine shaft, turbine hub and flywheel benefit from design, manufacturing and material upgrades to further improve maintenance costs and reduce downtime, Allison said. The transmissions have also received software updates.

Company News

In mid-2010, Allison dedicated a new hybrid manufacturing plant in Indianapolis, Ind. Once fully operational, the facility will be capable of produc-ing more than 20,000 commercial-duty hybrid propulsion systems each year. The new plant represents a $130 million investment, the company said.

Allison also announced plans to build a new advanced manufacturing plant in Szentgotthard, Hungary. The new facility is expected to produce 3000, 4000 and Torqmatic Series fully automatic transmissions for Europe.

AUBURN GEAR

planetary drive that can accept several
types of plug-in hydraulic motors.
New Products
Auburn Gear introduced two new
products for mobile off-highway applica-
tions at ConExpo-Con/Agg. The Model
70CD is a new compact planetary
drive that incorporates a new geartrain
design and is available with a fully
integrated parking brake. It is designed
to accept several different cartridge-
style (plug-in) hydraulic motors and is
available with a maximum intermittent
output torque rating of 70,000 lb.in. and
a broad range of ratios.

CARLISLE
Company News

At the beginning of the year, Carlisle Brake & Friction began operations from its new global headquarters in Solon, Ohio, at the site of the former Wellman Products Group. In late 2010, Carlisle completed its purchase of Wellman from the Hawk Corp.

With that acquisition, Carlisle now offers a range of friction products, including friction materials for clutches, dry and wet brake systems, transmissions, motion control systems and structural components. Products for off-highway applications are sold under the Wellman Products, Carlisle, Hawk Performance, Japan Power Brake, Velve Touch and Field Pro brands.
