Problems solved by technology
[0003] Therefore, in the above situation, the displacement output by the quantitative pump is related to the rotational speed of the engine, but it is also subject to the high-speed operation of the engine. Output oil, which will inevitably lead to the need to use the safety valve in the circuit to unload the output oil, resulting in higher power loss
[0004] In view of the above problems, in the existing teachings, a variable displacement pump that adjusts the output oil displacement according to the engine speed is designed, such as an internal meshing variable displacement rotor pump, but such an internal meshing variable displacement rotor pump is in order to realize Variable displacement, insufficient reliability, and the structure is too complicated, and the manufacturing cost is also increased, which is not conducive to practical application

The invention provides a variable displacement pump and a vehicle, and relates to the technical field of pumps. The variable displacement pump comprises a containing part, an inner rotor and an outer rotor, wherein the inner rotor and the outer rotor are arranged in the containing part and form internal meshing; and the variable displacement pump further comprises an adjusting component arranged on the outer rotor, and the adjusting component is arranged in the manner that when the adjusting component moves, the outer rotor is driven in the manner that the distance between the axis of the outer rotor and the axis of the inner rotor is not changed. According to the variable displacement pump, the outer rotor is driven in the manner that the distance between the axis of the outer rotor and the axis of the inner rotor is not changed, so that a maximum containing cavity formed by meshing of the inner rotor and the outer rotor is adjusted, and variable displacement is achieved; and in the using process, the distance between the axis of the inner rotor and the axis of the outer rotor is not changed, the situation that the inner rotor and the outer rotor are stuck is avoided, and the reliability of the product is greatly improved.
Description
technical field [0001] The present application relates to the technical field of pumps, in particular to a variable displacement pump and a vehicle. Background technique [0002] Existing metering pumps have many applications, such as being used as an oil pump in a vehicle, driven by the engine to provide the engine with oil for lubrication. [0003] Therefore, in the above situation, the displacement output by the quantitative pump is related to the rotational speed of the engine, but it is also subject to the high-speed operation of the engine. Oil output, which will inevitably lead to the need to utilize the safety valve in the circuit to unload the output oil, thus resulting in higher power loss. [0004] In view of the above problems, in the existing teachings, a variable displacement pump that adjusts the output oil displacement according to the engine speed is designed, such as an internal meshing variable displacement rotor pump, but such an internal meshing variabl...
