Definitions
- the invention relates to a transmission with a heat exchanger according to the preamble of claim 1.
- the transmission oil In modern, highly stressed vehicle transmissions, the transmission oil must be cooled to temperatures that are not critical to the system. Corresponding cooling devices in the form of a heat exchanger are provided in particular in areas with a high ambient temperature and in vehicles in which an encapsulation of the transmission is provided for reasons of noise reduction.
- the heat exchangers are usually used for additional cooling of the transmission oil, but they can also be used to heat the transmission oil during the warm-up phase of the transmission.
- the heat exchangers known today are either 01 / air or oil / water heat exchangers and are installed as additional components at a suitable point in the vehicle. Oil / water heat exchangers can also be integrated into the engine cooling circuit of the vehicle.
- the transmission cooling system comprises a transmission housing in which the transmission wheels are accommodated and which defines an oil sump for the transmission lubricant oil. At least some of the gear wheels rotate within the oil sump. In the oil sump of the gearbox, only that oil comes into contact with the heat exchanger and can transfer its heat to it, which is in the immediate vicinity of the heat exchanger. There is no forced routing of the oil present in the transmission past the heat exchanger to give off the heat to the latter. Such guidance is deliberately avoided by omitting a pump device suitable for guidance.
- the invention has for its object to make a transmission cooling system more efficient.
- a transmission has a transmission housing which comprises an area in which gearwheels rotate.
- the transmission also has a heat exchanger which receives heat generated in the transmission and transferred to a transmission lubricant and releases it to a coolant for transporting the heat away from the transmission.
- a recess is provided, through which the gear lubricant flows and in which the heat exchanger is arranged.
- the heat exchanger is advantageously a separate component that can be inserted into the recess in the gear housing.
- the gear lubricant flows through the recess in the gear housing on the suction side of a pump that pumps the gear lubricant.
- One embodiment shows that a by-pass valve is provided on the suction side of the pump delivering the gear lubricant, which enables the heat exchanger to be bypassed at temperatures of the gear lubricant below a predetermined limit value.
- the heat exchanger in the recess is advantageously accessible from outside the housing.
- One embodiment shows the heat exchanger as a tube-bundle heat exchanger.
- the coolant for removing the heat from the transmission is connected to a cooler outside the transmission.
- the embodiment is particularly advantageous when the coolant for removing the heat from the transmission is a coolant in the cooling circuit of an internal combustion engine that drives the transmission.
- the coolant is preferably a water-based liquid and the gear lubricant is an oil-based liquid.
- the gear housing forms the housing for the heat exchanger directly.
- all of the geared lubricant delivered is forced through the heat exchanger.
- This improves the efficiency of the heat exchanger and achieves a significantly smaller and more compact design.
- Short ducts and a large flow cross-section, which can be represented by the consequent integration into the gear housing, result in a very low pressure drop.
- Only simple and inexpensive adaptation parts are required for oil guidance, sealing and fastening. Simple and proven technology is also guaranteed with regard to the connection of the coolant without additional sealing elements.
- Fig. 1 is a schematic representation of a vehicle
- Fig. 3 installed the heat exchanger according to Fig. 2;
- Fig. 4 is a view of the gear housing
- Fig. 5 shows a further view of the gear housing.
- FIG. 1 shows a schematic representation of a vehicle 2 with a drive motor 4, which acts on a transmission 8 via a friction clutch 6.
- the transmission 8 is connected via an output shaft 10 to a differential 12, which drives a vehicle wheel 16 via a semi-axis 14.
- the friction clutch 6 is actuated by an actuator 18, which is connected to a controller 22 via a signal line 20.
- the transmission 8 is actuated by a transmission actuator 24 which is arranged on the housing 26 of the transmission and which is connected to the controller 22 via a line 28.
- a heat exchanger 30 is used, which is connected to the engine 4 and its coolant via two coolant lines 32 and 34. The warmed coolant is cooled down in a vehicle radiator 36.
- a cooler 38 mounted on the vehicle 2 can be connected to the heat exchanger 30 via the coolant lines 40 and 42, in which the coolant of the heat exchanger 30 is then cooled down.
- the heat exchanger 30 is connected to an oil sump 64 and an oil pump 62 which supplies oil to gear wheels 66, 68 in a region of the Gear housing 26 leads.
- the transmission oil does not flow through the heat exchanger 30, but is pumped through a by-pass valve 70, bypassing the heat exchanger 30.
- FIG. 2 shows the heat exchanger 30, which is designed here as a shell-and-tube heat exchanger.
- the inlet opening 44 is connected to the one coolant line 32 and the outlet opening 46 is connected to the other coolant line 34.
- FIG. 3 shows the heat exchanger 30 integrated in the gear housing 26.
- the heat exchanger is held only by a flange 52 sealed by sealing rings 48 and 50, which is supported by a locking ring 54. Sealing ring 50 and flange 52 can also be formed in one piece with the heat exchanger 30. Coolant enters the interior of the heat exchanger 30 via the openings 44 and 46.
- the heat exchanger 30 is arranged in a recess 56 in the transmission housing 26 in such a way that the transmission oil sucked in by the oil pump 62 from the oil sump 64 (FIG. 1) through the oil inlet opening 58 enters the recess 56 and can flow around the heat exchanger 30 there.
- the gear oil forcibly leaves the recess 56 at the oil outlet opening 60 and is sucked off in the direction of the oil pump 62.
- FIG. 4 shows a section of the transmission housing 26 with the oil inlet opening 58, the oil outlet opening 60 and a filler opening 72 for the transmission oil.
- the inlet opening 44 and outlet opening 46 for the coolant can be seen on the heat exchanger 30.
- FIG. 5 shows a view of the recess 56 with the heat exchanger removed.
- the oil inlet opening 58, the oil outlet opening 60 and the filler opening 72 for the transmission oil can be clearly seen in the recess 56.
