Powertrain

Caterpillar has earned a reputation for building some the world's most reliable engines and transmissions.  But that's not the whole story.  We leveraged decades of experience in a variety of markets to develop Cat powertrain systems that are performance-matched to meet OEMs application requirements.

When optimized for OEMs application, Cat powertrain systems integrate and communicate with other powertrain components to provide the power, shifiting options and ease of operaton your customers require.  This complete powertrain solution delivers increased fuel effciency and smooth operation, thus enhancing lifecycle value.  The toughness and durability of every Cat powertrain begins with innovative engineering.  We work with OEMs in a wide variety of industries around the globe and stand ready to offer the same proven capabilities.

Axles

Caterpillar offers a broad line of inboard and outboard planetary drive axles for heavy duty applications.

Cat® axles provide high durability, low sound levels, and traction control on uneven or poor terrain. Caterpillar offers a wide variety of models and load capacities. Caterpillar's heavy-duty design withstands the type of shock loading that occurs during all-terrain operation.

  • Heavy-duty design features stronger gears and bearings for durable performance.
  • Duo-cone metal face seals between the axle shafts and housing keep oil in and contaminants out.
  • Oil-disc brakes are adjustment free and fully enclosed.
  • Optional front and rear limited-slip differentials provide maximum traction in poor underfoot or uneven floor conditions.
  • A No-SPIN differential is available to deliver maximum traction in low-traction or inconsistent ground conditions.

Transmissions

We develop each transmission to integrate with other powertrain systems and components.

OEMs in industries as varied as forestry, locomotive, material handling, agriculture and mining rely on Caterpillar to design and manufacture their transmissions. We develop each transmission to integrate with other powertrain systems and components - including the engine, axle, electronics, hydraulics, and operator interface - to deliver maximum power while optimizing the performance of the complete powertrain system.

Leveraging decades of service to the agricultural and related industries, Caterpillar has developed solutions to the challenges facing many of today's original equipment manufacturers. Working with OEMs that service the agricultural industry, Caterpillar produced a new line of high capacity, high efficiency direct-drive transmissions.
