Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • This invention relates generally to apparatus for regulating the temperature of transmission fluid and engine coolant in a motor vehicle.
  • 2. Description of the Prior Art
  • A transmission cooling system may include an oil-to-water cooler or an oil-to-air cooler, or both of these, which remove heat contained in the transmission oil and are sized to accommodate a heat load produced when the transmission is operating under severe duty conditions. To reduce transmission friction, it is desirable to run the transmission at a relatively high temperature. The higher temperature reduces oil viscosity, which is one of the larger contributors to internal friction.
  • A cooler bypass valve may be used to reduce heat transfer from the transmission oil when cooling is not desired, so that internal friction can warm the transmission oil to the desired operating temperature. But cooler bypass valves have limited effect on warm up rates after a cold start.
  • An oil-to-water cooler located in the heater loop uses engine coolant to heat the transmission, especially after cold starts. This cooler has an advantage over an oil-to-water cooler installed in the radiator, in which no coolant flows until the engine reaches its desired operating temperature due to a closed thermostat. Although the oil-to-water cooler located in the engine coolant loop provides a solution for light duty vehicles, it is not capable of cooling heavier duty applications, such heavy duty trucks and other towing vehicles, due to their high coolant temperatures and a need for the transmission to run at temperatures close to the maximum engine coolant temperature.
  • Furthermore, performance of the passenger compartment heater is compromised when engine coolant is used to heat the transmission. Warming the transmission causes a lower coolant temperature, which reduces heater performance and slows delivery of heat to the passenger compartment.
  • SUMMARY OF THE INVENTION
  • A system for controlling the temperature of a transmission fluid includes a first heat exchanger communicating with a source of engine coolant for transferring heat between the engine coolant and the transmission fluid (sometimes called oil or ATF) and including a first outlet through which transmission fluid exits the first heat exchanger, a second heat exchanger through which air may flow for transferring heat between the transmission fluid and the air and including a second inlet through which transmission fluid enters the second heat exchanger, and second outlet through which transmission fluid exits the second heat exchanger, and a first bypass valve for alternately opening and closing the second inlet and the second outlet when a temperature of transmission fluid exiting the first outlet is greater than a first reference temperature, and for bypassing the second heat exchanger when the temperature of transmission fluid exiting the first outlet is less than the second reference temperature.
  • The engine coolant side bypass valve bypasses the ATF heat exchanger whenever the heat core discharge temperature is below a desired threshold. Then the first heat exchanger can be nearly any size without compromising the rate at which temperature of the heater core increases below that threshold. Above that temperature threshold, the bypass valve will open, thereby admitting coolant into the first heat exchanger.
  • ATF always flows through the heat exchanger. The second bypass valve senses the return oil temperature and, that temperature is below a reference temperature, e.g. 200° F., it will return to the transmission, which is a bypass to any auxiliary cooler in the ATF cooling loop. If the oil temperature is greater than the reference temperature, the ATF bypass valve opens, thereby admitting oil to flow to the auxiliary cooler, then return to the transmission.
  • The system provides additional packaging advantages when including both the water-side bypass, ATF-bypass and first heat exchanger as one assembly.
  • The scope of applicability of the preferred embodiment will become apparent from the following detailed description, claims and drawings. It should be understood, that the description and specific examples, although indicating preferred embodiments of the invention, are given by way of illustration only. Various changes and modifications to the described embodiments and examples will become apparent to those skilled in the art.
  • DESCRIPTION OF THE DRAWINGS
  • The invention will be more readily understood by reference to the following description, taken with the accompanying drawing, in which:
  • The FIGURE is a schematic diagram of a system for controlling the temperature of automatic transmission fluid.
  • DESCRIPTION OF THE PREFERRED EMBODIMENT
  • A automatic transmission 10 includes a oil sump 12, which is a source of transmission fluid, from which transmission fluid is supplied to the intake side of a transmission pump (not shown) and into which fluid is delivered from the hydraulic circuit of the transmission after the fluid lubricates and carries heat from the clutches, bearings, shafts, gears and other components of the transmission.
  • A first heat exchanger 14, which communicates with the source of transmission fluid 12 through an oil line 16, is adapted to carry engine coolant and to transfer heat between the engine coolant and the transmission fluid. Heat exchanger 14 includes a first inlet 18 through which transmission fluid enters heat exchanger 14 from line 16, and a first outlet 20 through which transmission fluid exits the heat exchanger and enters a line 22.
  • A second heat exchanger 24 includes a passageway through which ambient air may flow, transfers heat between the transmission fluid and the air. Heat exchanger 24 includes a second inlet 26, through which transmission fluid enters the second heat exchanger through an oil line 28, and second outlet 30, through which transmission fluid exits the second heat exchanger through an oil line 32.
  • A first bypass valve 34 is supplied through line 22 with transmission fluid exiting heat exchanger 14 at outlet 20 and includes an outlet 36, through which transmission fluid is carried in oil line 38 to the fluid source 12. Oil lines 28, 32 communicated bypass valve 34 and heat exchanger 24.
  • Bypass valve 34 opens communication through the second inlet 26 and second outlet 30 when the temperature of transmission fluid exiting the first outlet 20 is greater than a first reference temperature. Bypass valve 34 causes transmission fluid to bypass second heat exchanger 24 and to flow directly into fluid source 12 when the temperature of transmission fluid exiting the first outlet 20 is lower than the second reference temperature. This bypass valve 34 closes communication through the second inlet 26 and second outlet 30 when the temperature of transmission fluid exiting the first outlet 20 is greater than a first reference temperature.
  • Preferably the first reference temperature is about 200° F., and the second reference temperature is about 190° F. Preferably bypass valve 34 is a bypass valve of the wax motor type that is used in automatic transmission cooler loops by various automotive manufacturers.
  • As engine 40 includes a chamber 42, i.e., a source of engine coolant, in which engine coolant circulates around the combustion chambers of the engine and from which engine coolant is supplied to a third heat exchanger, which may include a radiator 44, or a heater core 46, or both the radiator and heater core. An engine coolant circuit includes coolant line 48, which carries coolant from the coolant source 42 to heater core 46; a coolant line 50, which carries coolant from the heater core 46; and coolant line 52, which carries coolant to the engine 42.
  • Coolant lines 50, 52 carry coolant to and from a second bypass valve 54. The second bypass valve 54 opens and closes communication between heater core 46 and engine 42 when the temperature of engine coolant entering bypass valve 54 is less than a third reference temperature, which results in the coolant bypassing heat exchanger 14. Bypass valve 54 closes communication between heater core 46 and engine 42 when the temperature of the engine coolant entering valve 54 is greater than the third reference temperature.
  • Preferably the third reference temperature is about 30° F. Preferably bypass valve 34 is a bimetal bypass valve used frequently to bypass the radiator.
  • Preferably heater core 46 is located in a passenger compartment 60, engine 40 and radiator 44 are located in an engine compartment 62, and coolant bypass valve 34, ATF bypass valve 54 and heat exchanger 14 are incorporated in a subassembly 64, which is attached to the transmission 10 and located in the engine compartment. Alternatively, coolant bypass valve 54 and heat exchanger 14 are incorporated in a subassembly, which is attached to the transmission 10 and located in the engine compartment, but the ATF bypass valve 34 is located in either heat exchanger 24, i.e., the auxiliary cooler, or in lines 28, 32.
  • In accordance with the provisions of the patent statutes, the preferred embodiment has been described. However, it should be noted that the alternate embodiments can be practiced otherwise than as specifically illustrated and described.
