Abstract

The invention discloses a vehicle energy-saving type assist steering oil pump which comprises a steering oil pump body and a belt pulley, wherein an electromagnetic clutch is arranged between the belt pulley and the steering oil pump body and comprises a transmission disc, an electromagnet core and a coil, the transmission disc is located on the inner side of a belt pulley hub, the electromagnet core is located on the inner side of the transmission disc, the coil is arranged in the electromagnet core, a friction plate is arranged on the side surface, facing the belt pulley hub, of the transmission disc, and an electrophoresis paint material layer matched with the friction plat is arranged on the surface of the belt pulley hub. According to the vehicle energy-saving type assist steering oil pump, the electromagnetic clutch is arranged, the on and off of power transmission between the belt pulley and the steering oil pump body is controlled, the power of an engine is saved, and oil consumption and discharge of the engine are reduced; the electrophoresis paint material layer is arranged on the surface of the belt pulley hub, so that the contact area of the electromagnetic clutch and the friction plate can be increased, the friction force is increased, the belt pulley can be prevented from skidding, the reliability is improved, and at the same time, the electrophoresis paint material layer has a rust-proof effect on the belt pulley.

Description

technical field [0001] The invention belongs to the technical field of vehicle power steering, in particular, the invention relates to a vehicle energy-saving power steering oil pump. Background technique [0002] The traditional power steering oil pump used on vehicles is driven by the engine through the belt pulley. The working state of the steering oil pump can only be determined by the working state of the engine, and has nothing to do with whether the steering pump needs to work. At present, the electric hydraulic power steering pump is directly driven by the motor, and the control unit controls the operation of the motor to change the working state of the steering oil pump. Although the working state of the oil pump can be adjusted according to the steering requirements, the structure is complex and the cost is high. Contents of the invention [0003] The invention provides an energy-saving power steering oil pump for vehicles, which solves the problem that the tradi...
