Abstract

The invention relates to a hybrid electric motor controlled silicon oil fan clutch. The clutch includes a front cover, a driving disc, a rear cover, a flange shaft, a solenoid and a brushless motor. The rear cover is fixedly connected to the fan, and the front cover is connected to the The back cover is fixedly connected, the driving disc is set between the front cover and the back cover, the flange shaft passes through the back cover and is threadedly connected with the driving disc, the flange shaft is connected with the engine crankshaft or pulley, the solenoid is arranged on the flange shaft, and ECU connection, the brushless motor includes a stator part and a rotor part, the rotor part is fixedly connected with the rear cover, and the stator part is fixed with the engine block. The invention optimizes the structure of the traditional electronically controlled silicon oil fan, introduces a brushless motor, combines the brushless motor and the traditional silicon oil fan, realizes the comprehensive utilization of electric energy, diesel oil, natural gas and other new energy sources by the electronically controlled silicon oil fan, and improves the energy efficiency.

Description

technical field [0001] The invention relates to a silicon oil fan in a commercial vehicle engine cooling system, in particular to a hybrid electric motor electronically controlled silicon oil fan clutch. Background technique [0002] At present, in the cooling system of the commercial vehicle platform, the engine cooling fan is mainly controlled by the electronically controlled silicon oil clutch. The torque of the engine is transmitted to drive the cooling fan to work, to dissipate heat for the radiator, intercooler, condenser, etc. of the engine thermal system parts, and to ensure the normal operation of the engine system. [0003] With the increasingly stringent emission requirements of China VI and VII, electronically controlled silicone oil fans have gradually replaced traditional temperature-controlled silicone oil fans because of their precise control, fast response, low fuel consumption, and low emissions. They are favored by commercial vehicle manufacturers and are ...

AI Technical Summary

Problems solved by technology

The traditional electronically controlled silicon oil fan is driven by engine torque, which consumes diesel and natural gas energy, and cannot use other new energy sources, resulting in a low overall energy utilization rate. At the same time, the hybrid vehicle will have ample electric energy that cannot be consumed and will be wasted; in addition, The idle speed of the traditional electronically controlled silicon oil fan is around 500rpm, and the speed is relatively high, so the power consumption is relatively high; when the vehicle is parked and the engine is idling, the air conditioning system cannot be turned on normally, and the driver feels bad when using it; currently, the electronically controlled silicon oil fan is cold-started The characteristics are not good, which means that when the vehicle starts to drive at low speed, the fan will be fully meshed, and only after the vehicle has been running at high speed for a period of time, it will gradually start to separate, which will cause the engine water temperature to be too low and cause engine damage; traditional electronic control The silicone oil fan only adjusts the speed through the torque transmitted by the silicone oil, so it cannot achieve precise speed regulation. Generally, the speed will change around the set speed ±100rpm; when the traditional silicon oil fan is working, when the speed control is unstable, there will be noise. The comfort of the driving environment is poor, while the engine life is low and the cost of maintenance is high
