Description
Technical Field
The invention belongs to the technical field of automatic transmissions, and particularly relates to a cooling system for an automatic transmission.
Background
Automatic transmissions are typically equipped with a cooling system for cooling various portions of the overall transmission. The common cooling system consists of three parts, a valve plate pressure starting point, a transmission oil circuit system and an oil cooler.
As shown in fig. 1 and 2, in a conventional cooling system, when a transmission is in a working state, high-temperature ATF oil enters a rubber oil inlet pipe 5 from a transmission main housing 6 through an oil pipe joint 4 at a pressure of up to 3bar, then enters an oil cooler 1, is cooled by the oil cooler 1, and then enters the transmission main housing 6 from a rubber oil outlet pipe 2 through the oil pipe joint 4, so as to enter a transmission complete machine cooling system.
In the process of implementing the invention, the inventor finds that the prior art has at least the following defects: current cooling system is connected to oil cooler and derailleur through outside rubber oil pipe, and along with the increase of time, rubber can be because of external environment (high temperature, high and cold, dust) produces fatigue aging, and 3 clamping parts of kneck clamp are cracked easily, can further increase the oil leak risk.
High-temperature and low-pressure ATF oil circulates in an oil circuit of a cooling system for a long time, and the oil circuit is corroded, so that the oil pipe is aged and cracked. Although the external rubber oil pipe can be replaced by a metal pipe, the metal can expand with heat and contract with cold at different temperatures, so that potential safety hazards exist; meanwhile, the oil pipe arranged outside occupies the space of other parts, and becomes complicated when spatial arrangement is carried out.
Because the whole vehicle arrangement requires that the clearance between the heat radiation fan and the speed changer is more than 80mm, when the whole vehicle is arranged, the heat radiation fan is close to the side of the power assembly, and other parts with larger external dimensions are not allowed to be attached to the power assembly, so that the attached parts are prevented from colliding and interfering with the heat radiation fan when the power assembly is turned over.
In addition, the position of the oil cooler is also an important aspect, the traditional oil cooler 1 is arranged on an oil pan 9 on the side face of the transmission, the position of a whole vehicle fan is arranged right in front (on the left side) of the oil cooler 1, the middle gap is about 60mm generally, the position is small, and the position is not favorable for arrangement requirements.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a cooling system for an automatic transmission, which overcomes the defects of the existing cooling system, and the cooling system of the invention realizes the following purposes:
in the long-term use process of the transmission, the cooling pipeline can not be leaked due to the influence of the external environment or the internal work circulation.
The external oil cooler of the transmission is connected with an oil line of an internal oil pipe of the transmission, so that the cooling of the whole machine is realized; and arrange the oil cooler in the whole quick-witted size range of derailleur, need not occupy the space beyond the derailleur alone, reduced the overall dimension of derailleur, do benefit to the arrangement design of derailleur in whole car more.
In order to solve the technical problems, the technical scheme of the invention is as follows: a cooling system for an automatic transmission, the automatic transmission includes a transmission main casing body, an oil cooler, the transmission main casing body includes an output shaft casing and a transmission shaft casing, its characterized in that: the oil cooler is arranged above the rear side of the output shaft shell and close to the position of the transmission shaft shell.
Further, a metal oil inlet pipe is arranged in the main shell of the transmission;
the oil inlet end of the metal oil inlet pipe is communicated with the valve plate, and the oil outlet of the metal oil inlet pipe is communicated with the oil cooler.
Furthermore, a metal oil outlet pipe is also arranged in the transmission main shell;
an oil inlet of the metal oil outlet pipe is communicated with the oil cooler, and an oil outlet of the metal oil outlet pipe is communicated with a main lubricating oil inlet of the intermediate partition plate.
Furthermore, a water pipe connected with a cooling system of the whole vehicle is arranged on the oil cooler.
By adopting the technical scheme, compared with the prior art, the invention has the following advantages: the oil cooler is arranged in the concave part between the output shaft shell and the transmission shaft shell, so that the thickness of the oil cooler and the size of a speed changer are reduced, the distance between an oil pan and a fan of the whole vehicle is increased, the arrangement of parts of an engine cabin of the whole vehicle is convenient, and the heat dissipation of the whole vehicle is facilitated; the oil pipe sets up in the derailleur main casing, has avoided the derailleur to lead to the oil leak because of the oil circuit is external, has taken other part spaces and the problem of external tubular metal resonator expend with heat and contract with cold, has solved simultaneously in the aspect of the whole car arranges that oil cooler and whole car fan space are not enough, has reduced the overall dimension of whole derailleur, and convenient matching is arranged. In the packing transportation process of derailleur, the transportation of derailleur also can more be do benefit to the new scheme design of arranging, the deformation that leads to the oil cooler of colliding with that prevents to produce on the way of transporting, perhaps the deformation of oil pipe.
The clamp and the oil pipe joint are completely eliminated, the production cost is reduced, and the assembly process is simplified.
