Hydraulic Power Regeneration System (HPRS)

While using the hydraulic regeneration system the mechanical or exhaust brakes can be added to the braking force to quicken deceleration. In power regeneration programs they work together. Tail shaft drop box regeneration systems, such as EATON HLA, have one advantage as they are an analogue system – i.e. It is infinitely variable to adjust the braking power and is smooth.

However:

There is the step-up gearbox, clutch and expensive heavy piston pump giving high cost and weight.

  • It cannot work over 40 KPH.
  • Has poor performance below 10 KPH as the piston pump shaft speed is low.
  • They work to 420 bar/6,000 PSI to try to accommodate these limitations.
  • The pump can not be used for any other function.
  • They have to carry separate oil reservoirs, as they need super clean oil – No steering, tipper etc, type hydraulic systems can share the special oil.

Our system is on the engine side of the gearbox and the pump/motors are running at close to optimum speeds regardless of road speed.

  • The pumps can work to 100+ KPH and still act as brakes and regenerators.
  • Our pumps can be used for tipper, steering, waste collection etc
  • Three pumps give seven steps, and gearbox changes occur simultaneously for smooth operation
  • Adding the on/off power steering pump gives four pumps and up to 25 steps in a digital mode, and at the same time the gearbox is changing gears again.

Thus we can save and reuse more energy; save cost and save weight. On tippers/concrete agitators and the like, we already have an oil reservoir of considerable capacity.

 

 

 

 

 

 

 

 

 

Our proposal is to use 3 FSV pumps on the Rear Engine Power Take Off prior to the gearbox.

  • Typical Analysis:•Pump A + B + C.
  • Accumulator charged to 70 bar/1,000 PSI nitrogen
  • Initial braking power:•Equals - A + B + C x 70 bar
  • i.e. Volume x Pressure

Assume in 3 pumps the volume was 600 litres per minute – the braking power starts at 120 HP. If we let the pressure rise to 210 bar or 3,000 PSI the braking is 360 HP. Braking occurs from 7 to 10 seconds in general. The captured energy helps re-acceleration to save fuel.

Mathers designed vane pump/motor (MUMP) for the REPTO-REGEN system offers very high power density and value. This design is used to capture and re-use stored braking energy. This assembly is mounted on to the rear engine. Regeneration has digital variable braking control with 3 pumping sections available for regeneration. This provides seven combinations of braking.
