Abstract

The present invention provides a transmission system (102) for transmitting power in a cold milling machine from an engine (104) to a milling rotor (106). The transmission system (102) includes a first circuit (110), a second circuit (112), and a shaft (114). A first circuit (110) is disposed within a first plane (116) and is configured to be operatively driven by the engine (104). The second circuit (112) is disposed in a second plane (120) substantially parallel to the first plane (116) and configured to operatively drive the milling rotor (106). A shaft (114) joins the first circuit (110) to the second circuit (112), wherein the motor (104) and milling rotor (106) are axially offset.

Description

technical field [0001] The present invention relates to a transmission system, and more particularly to a transmission system for transmitting power from an engine to a milling rotor in a cold milling machine. Background technique [0002] A cold planer is a machine that uses its milling rotor to remove a layer of material (such as asphalt) from the road surface during paving operations. Cold milling machines typically have a drive train coupling the motor to the milling rotor. [0003] In some cases, cold planers can provide limited space for drive train installation. During the installation of the transmission system, the limited space creates tight space constraints, making it difficult to connect the transmission system at the position of the engine and the milling rotor. For example, space constraint issues may require that the transmissions for the motor and milling rotor be arranged non-coaxial and non-coplanar with each other. As a result, manufacturers of large c...
