Description Type PDF Literature ID


The Series 10 steering unit is a robust design with balanced architecture that is based on proven technology. Eaton’s new Series 10 steering units are a blend of all the capabilities of the previous Standard and Metric Steering units with some new, exciting features. The Series 10 is the only steering unit on the market capable of 275 bar [4000 psi] continuous pressure rating. This product line also has a square mounting pattern for interchangeability with both Eaton standard and metric units as well as competitive units from Danfoss, Ognibene, and M&S

Char-Lynn® Steering Control Unit Series 10 Dual Displacement

Steering

Dual Displacement SCU Description Type PDF Literature ID

The dual displacement steering control unit allows manufacturers of off road vehicles to retain manual steering capabilities while reducing the number of components in their system. By using two displacements in one unit we offer a better solution to manually steer a vehicle in an unpowered mode without the need of a back-up power system - resulting in a more economical machine. The dual displacement steering unit uses two gerotors and a pressure controlled logic valve. The logic valve switches between two displacements, one displacement for manual steering and the total of both displacements for powered operation. The logic valve is spring returned to the smaller manual displacement when inlet pressure falls below 8 bar [120 psi]. Above 8 bar [120 psi] the logic valve connects both gerotors to provide full powered displacement.

 Manual Steering in unpowered mode

  • Eliminates the need of a back-up emergency system.
  • Engages the small displacement in an unpowered mode and allows manual steering.
  • Allows vehicles to meet ISO/TUV road regulations without the need of the currently used emergency system.

 Performance in powered Mode

  • Both gerotors are engaged to steer the vehicle.
  • Same performance as other Char Lynn steering units.

 Additional Features

  • Steering circuit: Load Sensing Dynamic Signal
    Max. system pressure: 240 bar [3500 psi]
    Valve options and other features: same as available on Series 230 units

Char-Lynn® Steering Control Unit Series 20

Steering

Series 20 Description Type PDF Literature ID


The Series 20 - steering control unit continues Eaton's tradition of innovative design and high quality that began with the first fluid linked power steering system. You can count on this steering unit to provide the same smooth, predictable steering as the Char-Lynn® steering units that provide dependable, trouble-free steering on applications around the world.

Features
  • Provides much smoother steering function by minimizing jerky motion on articulated vehicles.
  • Jerk-reducing valves and accumulators can be eliminated on most vehicles, providing customer savings through fewer components required and reduced system cost.
  • Symmetrical valving provides passageways and valving that are equally placed, and pressure areas that are staged for minimum internal leakage. This results in balance, precise servo response and uniform left or right steering action.
  • Eaton's high capacity gerotor provides ample fluid displacement from an even more compact unit than was previously offered.
  • A thicker sleeve design provides stability, especially during pressure and thermal transient conditions.
  • The seal and centering spring designs provide positive, low-effort steering feel to ensure excellent vehicle control, an important feature for the vehicles for which these steering control units were designed.
  • Load Sensing
  • Integral Valves
  • Q-Amp
  • Wide Angle

Char-Lynn® Steering Control Unit Series 25

Steering

Description Type PDF Literature ID

The Series 25 - steering control unit includes two patented designs that make it even more responsive, reliable and cost effective.

  • Articulated Vehicles
  • Loaders
  • Scrapers Frame Vehicles
  • Large Front End Loaders
  • Large Graders
  • Mining Trucks
  • Articluated Haulers
  • Transporters
  • Symmetrical valving provides passageways and valving that are equal in both directions and pressure areas that are staged for minimum leakage. This gives balance, precise servo response and uniform steering action in both directions.
  • Progressive valving makes it possible to produce the spool/sleeve valve in a way that assures reliability and reduces costs.
  • Eaton's high capacity gerotor assembly provides a lot of capacity in a small package.
  • Heavier valve components-housing, spool and sleeve-provides stability, especially during pressure and thermal transient conditions.
  • The seal and centering spring designs provides positive, low-effort steering feel assuring excellent vehicle control, an important feature on large vehicles for which this steering control was designed.
  • Cylinder port relief/check valves are needed on any machine that is subject to high steering cylinder pressures caused by external loads. For example, when one edge of an articulated front end loader bucket encounters an obstruction (external load), the full force of the load and the momentum of the machine causes the machine to buckle at the articulation point and raise pressure in the steering cylinders far in excess of system pressure. This pressure must be relieved to absorb the impact load and prevent damage to the hydraulic system and to the machine itself.
  • The traditional method of relieving system pressure involves interruption of cylinder port lines with a variety of fittings and plumbing. By designing cylinder port relief valve integral to the steering control unit housing, Series 25 steering control units equipped with cylinder port relief valves eliminate the additional hardware used to relieve pressure and return oil to the tank.
