Cleaning vehicle e.g. small sized commercial motor vehicle, for urban environment, has hydrocuring unit including transmission chain to transmit power from driving engine to high pressure pump, and another chain to transmit power to wheels

摘要

The vehicle has a hydrocuring unit (10) comprising a mechanical power transmission chain (52) transmitting power from a driving engine (14) e.g. electrical engine, to a high pressure pump (12). A transmission chain (54) transmits power from the engine to wheels (56). The chains are independent from each other. The engine rotates a shaft (60) at its end (61) to which a pulley (62) is fixed, where the pulley is made of titanium alloy.
