Avant has developed the Optidrive to improve the performance of the drive circuit in the company’s loaders.
The drive system consists of a variable displacement hydraulic pump, four hydraulic drive motors and valves that are connected by hydraulic hoses and fittings.
Such a system – where the drive power is conveyed from engine (electric motor on Avant e-series) to the wheels using hydraulic oil – is often referred to as a drive circuit. Instead of mechanical axles, Avant uses four separate hydraulic drive motors, one on each wheel of the loader.
Avant has now improved this system. When hydraulic oil flows at high flow rate in the drive circuit – in hydraulic hoses, fittings, motors and valves – the resistance in these components heats up the hydraulic oil. The more hoses and fittings there are, the quicker the oil heats up.
In the redesigned system, the number of hydraulic hoses and fittings has been radically reduced and optimised. Benefits include: 10% better performance, 60% fewer hydraulic connections and 20% fewer hoses, parking brake in rear wheels and an improved hydraulic connector system.
