Wheeled Loading Shovels презентация

Twin fixed displacement gear pumps (412S, 414S)
Oil is picked up on suction side of pump by the gears, oil is carried round the outer edge of the pump body by the gear teeth. When the gear teeth come into mesh – the oil is forced through the outlet port.
Both pumps provide oil for all services
Both pumps operate high flow at low pressure 412S = (131 l/min@170bar), 414S = (154 l/min@190bar) Example for: rapid loader arm lift!
One pump will cut of for the other to supply high pressure, low flow 412S = (54 l/min@220bar), 414S = (90 l/min@240bar) Example: for maximum breakout force!
DISADVANTAGES
Constantly drives oil around the circuit
Wastes engine power
Less fuel efficient
Higher running costs
Can create unwanted heat
ADVANTAGES
Simple technology
Inexpensive to repair
Gives instant supply of oil on demand

Transfers torque from the slipping wheel to the wheel with better traction
Uses clutch packs behind the side gears to provide up to 75% of the torque to the gripping wheel
Advantages
Reduced wheel spin increases tyre life
Machine performance is increased in all conditions with increased tractive effort
Despite locking action, still provides smooth distribution of torque when cornering
Limited Slip Differentials

Variable displacement piston pump – load sensing
Body contains a number of pistons arranged in a circle around a central driveshaft, Pistons are in contact with an angled plate (swashplate).
As the body is rotated, the volume in the piston bores moves from minimum to maximum - drawing oil in and pushing it out
Pump senses load requirements and varies swashplate angle accordingly
bigger angle for high flow at lower pressure
smaller angle for higher pressure at lower flow
Swash angle is minimal until a service is selected - oil is only pumped on demand
Advantages
Efficient use of engine power
Reduced fuel consumption
Lower running costs
Only delivers oil on demand
