The present invention relates to an oil cooling apparatus for hydrostatic transmissions that includes a cooling main body coupled to a transmission case in which a hydrostatic transmission is installed; an accommodating groove formed in the cooling main body to accommodate oil; a cover unit coupled to the cooling main body to cover the accommodating groove; a supply port configured to supply the oil to the accommodating groove; a discharge port configured to discharge the oil from the accommodating groove; a plurality of guide ribs installed at positions spaced apart from each other to guide a flow direction of oil flowing along a flow path formed in the accommodating groove; a first hurdle unit coupled to at least one of the guide ribs to form a first flow region through which the oil passes; and a second hurdle unit coupled to at least one of the guide ribs to form a second flow region through which the oil passes.

Oil cooling apparatus for hydrostatic transmissions

A cooling apparatus for a hydrostatic transmission includes a cooling body to be coupled with a hydrostatic transmission, a sidewall member protruding from the cooling body to surround a cooling flow path which cools a working fluid supplied from the hydrostatic transmission and discharges the working fluid into the hydrostatic transmission or a storage tank, an installing member protruding from the cooling body at a position spaced apart from the sidewall member to be disposed inside the sidewall member, a detour member connected to the installing member and protruding from the cooling body to extend in a first axial direction to allow the working fluid, which flows along the cooling flow path, to make a detour, and a plurality of protruding members protruding from the cooling body to be spaced apart from each of the sidewall member, the installing member, and the detour member in the cooling flow path.
