From Off to On Road Poclain Hydraulics is one of the leaders in Hydrostatic Transmission (HST) with Millions proven drives in : Agriculture Combine harvesters / Self propelled tool carriers / Sprayers / Vineyard harvesters and tractors Construction equipment Excavators / Compactors / Graders / Pavers / Cold planers / Screening plants Handling Forklift trucks / Straddle carriers / Conveyors / Container handlers
From Off to On Road Example: Tree Harvester
From off to On Road HST is now ready to help on road Pump Motor
How it works Transmission = Power Transfer Circuit Transporter Physics Mechanical Parts Rot Speed Electrical Electrical Charges (rad/s) [rad/s] Current (A) Hydrostatic Oil Flow (m 3 /s) [in 3 /s] Torque (Nm) [Ft lbs] Charge or Potential (V) Δ Pressure (Pa=N/m 2 ) [psi]
How it works In 1652, Pascal established the hydrostatic laws Incompressibility of liquids considered as a solid component in a transmission; Pressure evenly distributed in a closed tank. Hydrostatic means: static fluid Despite flow in the circuit, these laws apply to fluid velocity below 5m/s [15 ft/s]

Trucks concerned Addidrive TM Assist
Addidrive TM Assist % time Mechanical front drive Speed
Addidrive TM Assist Features Low speed (< 40 km/h) [< 25mph] assistance drive making the truck All Wheel Drive in case of: - Slippery conditions (mud, snow, wet grass ) - Very steep slope (up and down) Disengage above 40 km/h [19mph] No change in truck chassis and cab height Very little weight increase and maximum use of existing components (axle, brakes, cab, suspension) SmartDrive Electronic control
Addidrive TM Assist Designed for: Trucks occasionnally needing extra traction: - Dump trucks - Delivery trucks - Concrete mixers - Refuse trucks - Fire trucks - Ambulances Mountain conditions, especially winter
Addidrive TM Assist Advantage Continued operation in difficult situations (mud, snow, ice ) Goes the extra mile for delivery or dumping (concrete, material ) Cab and center of gravity stays at same height as on 4x2 End User Benefits Time and cost saving Productivity maintained Saves an extra carrier to deliver on site Visibility maintained (Safety preserved with same visual and driving habits) Easy access to cab maintained Fuel economy due to low wind drag maintained
Addidrive TM Assist Advantage Steering control in very steep downhill slippery conditions Automatic engagement / disengagement on the fly Works only when needed at low speed Disengages at high speed Very compact drive Saves 400 kg/ mechanically driven axle End User Benefits Increased vehicle control Driver stays focused on the job No damage due to improper operation No drag due to back driving HST at high speed; fuel economy maintained Ground clearance maintained Truck weight nearly maintained Best suspension maintained Fuel consumption preserved

HST Braking Function Addidrive TM Hybrid
Addidrive TM Hybrid Features 2 different drives: Mechanical or Hydrostatic Drive mode change at the flick of a switch Hydrostatic drive takes over in cities when frequent stop & start is required Hydrostatic drive takes over on working site when creeping motion is required 4 quadrant function (HST braking) SmartDrive Electronic control
Addidrive TM Hybrid Designed for: Garbage trucks Stop and Go Mail delivery trucks Municipal vehicle (hanging decoration) Utility boom trucks Creeping Highway paint strippers Aircraft de-icer Railroad maintenance trucks Man lift trucks
Addidrive TM Hybrid Advantage vs Mechanical Creeping mode without slipping clutch High torque motors have low inertia and are insensitive to start and stop Braking on HST End user Benefits No wear & tear of main transmission Smoothness and speed control Very little wear of clutch and gear = maintenance cost reduction No brake wear Brake noise reduced
Addidrive TM Hybrid Advantage vs Mechanical High torque motors have very high efficiency at low speed Automatic drive style Automatic disengagement at high speed Engine revs independent of ground speed End user Benefits Fuel consumption reduced Driver stays concentrated on the job No damage due to improper operation Noise reduction Power on request for the tools
Addidrive TM Regen Parcel Delivery
Addidrive TM Regen Mechanical drive Stop and go Frequency
Addidrive TM Regen Features Regenerates kinetic energy by: - Charging an accumulator when braking - Discharging to get in motion Motors in the wheels SmartDrive Electronic control
Addidrive TM Regen Designed for: Trucks fequently stopping and starting: - Busses - Mail trucks - Refuse trucks - Special shuttle trucks
Addidrive TM Regen Advantage Braking on HST is used to fill an accumulator instead of heating brake linings High torque motors have low inertia due to direct drive High torque motors have very high efficiency at low speed Automatic disengagement at high speed Benefits Fuel cost saving Pollution reduction Brake noise reduction Kinetic Regen Smoothstart Very little wear of clutch and gear = maintenance cost reduced Fuel consumption reduced No damage due to improper operation
