Abstract

The invention discloses an integrated oil pump for a transmission. The integrated oil pump is installed in the transmission, and an oil inlet, an oil inlet cavity, an oil suction cavity, an oil outlet cavity and a functional cavity are provided on the oil pump housing. All chambers of the oil pump are integrated on the oil pump assembly. The oil pump assembly is designed as a complete functional module. In addition, the functional cavity of the present invention is also designed with a channel leading to the outside of the oil pump casing, and the switch between forced lubrication and forced cooling can be realized by installing an oil plug or an oil pipe joint on the channel. Finally, the present invention does not need to design complex structures such as cavities on other related parts of the transmission, which saves space for the overall design of the transmission and reduces obstacles for the design and improvement of other parts.

Description

technical field [0001] The invention belongs to the field of transmission devices, and in particular relates to a transmission integrated oil pump. Background technique [0002] Installing an oil pump in the transmission of a heavy-duty commercial vehicle can perform forced lubrication and cooling of the transmission, which has become a development trend of transmissions at home and abroad. However, the internal structure of the transmission is compact, and the available space is very narrow. In order to realize the forced lubrication and forced cooling of the oil pump at the same time, in addition to the more complicated oil pump assembly, the design at home and abroad usually requires the design of auxiliary chambers on other housing parts of the transmission, which has a complex structure and involves many parts. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and to provide a tra...
