Abstract

"SISTEMA DE RESFRIAMENTO E APERFEIçOAMENTO PARA UMA MáQUINA". é comum na operação de uma máquina de construção utilizar diversos modos funcionais diferentes. Alguns modos podem utilizar predominantemente os sistemas de freagem da máquina, enquanto outros modos podem predominantemente utilizar o motor para operar os vários implementos. Em cada caso, um resfriamento suplementar desses sistemas é freq³entemente desejável. A presente invenção provê um sistema de resfriamento em que cada conjunto de eixo tem um sistema de resfriamento adicionalmente ao sistema de resfriamento convencional do motor. Todos os sistemas de resfriamento comunicam com um trocador de calor comum. Uma bomba é provida para circular óleo dos conjuntos de eixo, bem como resfriador do motor através do trocador de calor para reduzir a temperatura de um dos fluidos. Um par de sensores é engatado com o motor e os eixos para seletivamente atuar um membro de embreagem para prover engate de acionamento entre o motor e a bomba em resposta a qualquer um dos componentes atingir uma temperatura pré-selecionada."COOLING AND IMPROVING SYSTEM FOR A MACHINE". it is common in the operation of a construction machine to use several different functional modes. Some modes can predominantly use the machine's braking systems, while other modes can predominantly use the engine to operate the various implements. In each case, additional cooling of these systems is often desirable. The present invention provides a cooling system in which each axle assembly has a cooling system in addition to the conventional engine cooling system. All cooling systems communicate with a common heat exchanger. A pump is provided to circulate oil from the shaft assemblies, as well as the engine cooler through the heat exchanger to reduce the temperature of one of the fluids. A pair of sensors is engaged with the motor and the shafts to selectively actuate a clutch member to provide drive engagement between the motor and the pump in response to any of the components reaching a pre-selected temperature.
