Among all the countless parts that come together to form the new 2013 Ram 1500, there are a select few that help make this our most fuel-efficient truck to date. Two of those—the aluminum gear retainer and vane pump, both components of the TorqueFlite 8 Transmission—combine to become our next item up for bid in the Engineering A Giant auction for charity. Here’s more information on each of these important parts, courtesy of the Ram engineers.
- Vane Pump: Unlike more traditional, less efficient, larger-than-necessary pumps, the compact design of this off-centerline, chain-driven vane pump allows it to be optimally sized for the proper flow of oil to the TorqueFlite 8 Transmission. This makes it one of the major contributors to the new 2013 Ram 1500’s efficient fuel economy.
- Aluminum Retainer: The efficient architecture of the TorqueFlite 8 Transmission is enabled by parts such as this aluminum gear retainer. Transmission architecture dictates the need for a very long part rotating at high speeds. This drove a new high-tech aluminum casting process, which in turn allowed for very thin durable walls, keeping the rotating mass low and allowing for smooth operation in all conditions.
If that’s not enough tech talk for you, then tune in to the Engineering A Giant Facebook tab on Thursday, August 30, from 4 p.m. to 5 p.m., for a live chat with Ram engineers. They’ll be answering questions about Ram fuel efficiency as well as any you might have about Ram engineering in general.
