The Peterbilt 379 is a model line of Class 8 trucks that was produced by the Peterbilt division of PACCAR from 1987 to 2007. Serving as the successor to the 359, the 379 was a conventional-cab truck configured primarily for highway use, serving as the flagship of the Peterbilt model line.
Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering. [1]Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and considerably reduce the physical effort necessary to turn the ...
In 1994, the Unibilt sleeper debuted with air-ride suspension for the cab and sleeper with a large cab to sleeper opening. The Unibilt sleeper suspension had a one piece shock/air bag mount system from 1994 to 2006, until Peterbilt redesigned the suspension system for the 2007 model year, making the shock and air bag system on separate brackets.
1946 Peterbilt flatbed 1939 Peterbilt Model 334 (1 of 2 built 1939). In 1939, the Fageol plant in Oakland opened for business as Peterbilt Motors Company. As part of the design process, Peterman and his company engineers sought input from truck owners and drivers on how to develop trucks; [10] [11] initially planning to develop chain-drive trucks for the logging industry, the company ...
The system is fully regenerative: all of the engine's power reaches the track either through the main driveshaft or the steering system; none of the energy is being lost to brakes or clutches. Additionally, since power is fed around the transmission to the steering system, in some designs the tank can be turned or even pivoted in place even ...
Power steering helps drivers steer by augmenting the driver's steering effort. Power steering has used hydraulics to reduce a driver's steering effort. However, hydraulic steering is being replaced by electric power steering , because it eliminates the hydraulic pump, and increases fuel efficiency.

The steering pivot points [clarification needed] are joined by a rigid bar called the tie rod, which can also be part of the steering mechanism, in the form of a rack and pinion for instance. With perfect Ackermann, at any angle of steering, the centre point of all of the circles traced by all wheels will lie at a common point.
