DRIVING SYSTEM OF CONSTRUCTION EQUIPMENT

摘要

The present invention relates to a driving system of construction equipment comprises: a first pump supplying a working fluid, which operates a driving motor, through an engine; a first change valve enabling a flow of the introduced working fluid to be changed to operate the driving motor; a second pump supplying the working fluid operating an operating device different from the driving motor; and a second change valve supplying the working fluid introduced from the second pump to the operating device or supplying the entire working fluid introduced from the first pump and the second pump to the first change valve. According to the present invention, the driving system of construction equipment reduces driving noise generated by excessive engine operation and reduces the number of revolutions of the engine required in high speed driving to reduce the fuel consumption in accordance with a flow rate supplied to the driving motor with respect to the number of revolutions of the engine is increased. Therefore, driving fuel efficiency is capable of being improved.
