Embodiment Construction

[0015] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0016] Such as figure 1 as well as figure 2 The shown automatic transmission with a cooling system includes a case body, a speed change mechanism 40 and a cooling mechanism, and the speed change mechanism 40 is installed in the case body. Specifically, a cooling cavity and an installation cavity 10 are formed in the box; the above-mentioned speed change mechanism 40 is installed in the installation cavity 10 . The cooling cavity includes a first cavity 20 and a second cavity 30, both of which are used to store cooling liquid. The cooling mechanism includes a first cooling pipeline and a second cooling pipeline, and the first cooling pipeline can communicate with the first cavity 20 through a first pump body 23 . Likewise, the second cooling pipeline communicates with the first cavity 20 through a second pump body 24 . In addition, the first cavity ...

Abstract

The invention discloses an automatic transmission with a cooling system. The automatic transmission comprises a transmission body, a speed change mechanism and a cooing mechanism, wherein the speed change mechanism is mounted in the transmission body; a cooling cavity and a mounting cavity are formed in the transmission body; the speed change mechanism is mounted in the mounting cavity; the cooling cavity comprises a first cavity and a second cavity; both the first cavity and the second cavity are used for storing cooling fluid; the cooling mechanism comprises a first cooling pipeline and a second cooling pipeline; the first cooling pipeline communicates with the first cavity through a first pump body; the second cooling pipeline communicates with the first cavity through a second pump body; the first cavity is located on one side of the mounting cavity; and the second cavity is located at the bottom of the mounting cavity and communicates with the bottom of the mounting cavity. The automatic transmission realizes separate cooling of the speed change mechanism, avoids local overheating of the speed change mechanism and enhances the cooling effect. Used cooling fluid can be concentrated at the bottom of the mounting cavity and flows back into the second cavity.

Description

technical field [0001] The invention relates to the technical field of automatic transmissions, in particular to an automatic transmission with a cooling system. Background technique [0002] With the continuous improvement of people's demand for driving comfort, more and more car manufacturers are equipped with automatic transmissions for high-end models to meet different customer needs. During the transmission process of the automatic transmission, due to the continuous switching of the gear positions of the car, the transmission mechanism in the automatic transmission will generate high temperature, which will affect the operation of the transmission mechanism. Therefore, a cooling system is generally provided in the automatic transmission for cooling the transmission mechanism. However, the cooling system of the existing automatic transmission usually concentrates on cooling the transmission mechanism, and the cooling effect is relatively poor. Contents of the inventi...
