Abstract

The invention provides a water pump and a vehicle. The water pump comprises a main shaft, a joining piece, a middle shaft, an auxiliary shaft and an impeller, the joining piece is arranged on the mainshaft, is fixed relative to the circumferential direction of the main shaft and is movable in the axial direction, the middle shaft and the main shaft are fixed, the joining piece is located on the axial side of the middle shaft, the auxiliary shaft is located at the other axial side of the middle shaft and is separated from the main shaft, the impeller and the auxiliary shaft synchronously rotate, and one part of the joining piece is suitable for penetrating the middle shaft to be joined with the auxiliary shaft so as to enable the main shaft to drive the auxiliary shaft to synchronously rotate. When the joining piece is far away from the auxiliary shaft, the main shaft drives the joining piece to idle, the auxiliary shaft and the impeller stop rotation, at the time, the engine cold starting or machine heating working condition requirements can be met, the machine heating time can be shortened, and the machine heating efficiency can be improved. In addition, mechanical losses of an engine and a water pump can be reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a water pump and a vehicle with the water pump. Background technique [0002] Generally, the engine uses a conventional mechanical water pump, that is, the water pump impeller is driven to rotate under the drive of the water pump pulley to realize the water pump function. The speed of this mechanical water pump increases with the increase of the engine speed, so the supply of coolant also increases with the increase of the engine speed. improve. The maximum pumping water volume of the mechanical water pump is designed according to the cooling demand of the engine under full load conditions, but in the cold start, warm up and light load conditions of the engine, the pumping water volume of the mechanical water pump is greater than the cooling demand of the engine, which will prolong the engine warm up time , resulting in insufficient combustion, resulting in adverse consequences...
