Abstract:
Provided in the embodiments of the present application are an oil pump device and a vehicle. The oil pump device comprises an electric motor structure, which comprises a drive shaft; and a pump structure, which comprises a pump housing, and a pump rotor arranged on the pump housing, wherein the pump housing comprises a pump body, and a pump cover arranged at an axial end of the pump body; the pump rotor specifically comprises a first rotor structure and a second rotor structure, which are engaged with each other; the first rotor structure is connected to the drive shaft; the first rotor structure is provided with a first protruding portion extending to the electric motor structure; a friction pair is formed by the first protruding portion and the pump body; and a friction pair is formed by the pump cover and at least one of the drive shaft and the first rotor structure. In the technical solution of the present application, one friction pair is formed between the first protruding portion and the pump body, and the other friction pair is formed by the pump cover and the drive shaft or the first rotor structure, such that under the action of the two friction pairs, the effect of supporting the first rotor structure and the drive shaft can be greatly enhanced, and the overall external axial size can be reduced.
