Abstract
Description
Technical Field
[0001] The utility model relates to the field of engines, in particular to a fan structure of an electric drive clutch engine. Background Art
[0002] In existing hybrid vehicles, the engine serves as a direct power output to drive the wheels. The excess energy is used to drive the generator to generate electricity or directly serve as the generator power source to generate electricity and store energy to power the drive motor. During the operation of the vehicle, the power battery pack will continuously charge and discharge. In particular, when a tractor is running for a long time, the temperature of the power battery pack will rise and it needs to be cooled. The existing power battery pack condenser is arranged in front of the engine condenser and dissipates heat through the engine fan. When the car is parked and turned off, the engine stops running and the fan stops moving. The power battery pack cannot continue to cool down. The power battery pack rises and cannot be maintained in the appropriate temperature range of the battery. Frequently causing the power battery pack temperature to be too high will affect its performance and service life.
[0003] The disclosure of the above background technology content is only used to assist in understanding the utility model concept and technical solution of the utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of this application. Utility Model Content
[0004] The purpose of the utility model is to provide an electric drive clutch engine fan structure to solve the problem that after the existing hybrid vehicle is parked and turned off, the engine stops running and the fan stops rotating, the power battery pack cannot continue to cool down, and the power battery pack temperature is too high, affecting its performance and service life.
[0005] In order to achieve the above objectives, the technical solutions adopted by this utility model are as follows:
[0006] An electric drive clutch engine fan structure is characterized in that it includes an engine, a fan shaft seat, an intermediate shaft, an electromagnetic clutch, a fan and a motor, the fan shaft seat is installed on the cylinder block of the engine, the intermediate shaft is connected to the fan shaft seat, the electromagnetic clutch is installed on the right part of the intermediate shaft, the crankshaft of the engine is cooperatively connected to the electromagnetic clutch, the fan is installed on the left end of the intermediate shaft, and the motor is installed in the vehicle and connected to the left part of the intermediate shaft.
[0007] Furthermore, an additional pulley is provided on the crankshaft of the engine, and a first pulley is provided on the electromagnetic clutch; the crankshaft of the engine and the electromagnetic clutch are connected via a belt drive.
[0008] Furthermore, the motor is provided with a second pulley, and the left portion of the intermediate shaft is provided with a second pulley; the motor and the intermediate shaft are connected by belt transmission.
[0009] Furthermore, the motor and the electromagnetic clutch are controlled by an ECU of the engine.
[0010] Compared with the prior art, the advantages and beneficial effects of the present invention are:
[0011] The utility model arranges an electromagnetic clutch and a motor drive on an intermediate shaft. When the electromagnetic clutch is engaged, an additional pulley on the crankshaft drives the intermediate shaft via a belt to drive the first pulley, thereby driving the fan to suck air and continuously cool the engine and the power battery pack. When the vehicle stops and the engine is shut down, the electromagnetic clutch is disengaged, and the motor drives the second pulley to drive the intermediate shaft, thereby driving the fan to suck air and continuously cool the power battery pack, so that the battery pack is kept within a suitable temperature range, thereby improving the performance and service life of the power battery pack. The utility model solves the problem that when the engine of the existing hybrid vehicle stops running and the fan stops rotating, the power battery pack cannot continue to cool down, resulting in excessively high temperature of the power battery pack, which affects the performance and service life of the power battery pack. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION
[0013] The present invention will be further described in detail below in conjunction with specific embodiments. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.
[0014] like Figure 1 As shown, an electric drive clutch engine fan structure is characterized in that it includes an engine 1, a fan shaft seat 2, an intermediate shaft 3, an electromagnetic clutch 4, a fan 5 and a motor 6, the fan shaft seat 2 is installed on the cylinder body of the engine 1, and plays a role in supporting the intermediate shaft 3, the intermediate shaft 3 is connected to the fan shaft seat 2, the electromagnetic clutch is installed on the right part of the intermediate shaft, the crankshaft of the engine is matched with the electromagnetic clutch, the crankshaft 7 of the engine 1 is provided with an additional pulley 8, the electromagnetic clutch 4 is provided with a first pulley 9, and the crankshaft 7 of the engine 1 is connected to the electromagnetic clutch 4 by a belt drive; the fan 5 is installed on the left end of the intermediate shaft 3, the motor 6 is installed in the vehicle and connected to the left part of the intermediate shaft 3, the motor 6 is provided with a second pulley 10, and the left part of the intermediate shaft 3 is provided with a second pulley 10; the motor 6 is connected to the intermediate shaft 3 by a belt drive; the motor 6 and the electromagnetic clutch 4 are controlled by the engine ECU.
[0015] The principle of this utility model is:
[0016] When the engine is running, the additional pulley 8 on the crankshaft 7 drives the first pulley 9 via a belt. The electromagnetic clutch 4 engages, rotating the intermediate shaft 3 and driving the fan 5 to draw air to continuously cool the engine and battery pack. In this operating condition, the motor 6 is driven to idle.
[0017] When the vehicle is stopped and engine 1 is shut down, the battery pack still needs cooling. Motor 6 drives second pulley 10, which in turn rotates intermediate shaft 3. This drives fan 5 to draw air and continuously cool the battery pack, keeping it within a suitable temperature range and improving its performance and lifespan. In this operating condition, electromagnetic clutch 4 is disengaged and does not rotate crankshaft 7.
