Abstract
The utility model discloses a fan driving device, and particularly relates to a cooling fan driving device of a hydraulic excavator. The cooling fan driving device of the hydraulic excavator comprises a flange and a silicone oil clutch which is provided with a temperature sensor. The temperature sensor is electrically connected with an engine ECU. One end of the flange is connected with an engine fan pulley, and the other end of the flange is in matching connection with the silicone oil clutch. A fan is fixedly arranged on the silicone oil clutch through bolts. The cooling fan driving device of the hydraulic excavator has the advantages that the silicone oil clutch, the temperature sensor and the engine ECU are matched, under the premise that mounting space is not changed, the fan rotating speed can be adjusted, and heat balance of the entire machine is maintained.
Description
Technical field
The utility model relates to a kind of fan drive device, relates in particular to a kind of hydraulic shovel radiating fan driving device.
Background technique
Conventional hydraulic excavator radiation fan is directly installed on the engine blower driving wheel by transition block, rotation speed of the fan and engine speed keep constant ratio, heat dissipating capacity can't be regulated in the excavator warming-up process, especially extended at cold snap time that machine reaches optimum working temperature, cause great energy loss, also be accompanied by simultaneously noise pollution.Although independent radiation system preferably resolves this problem, be limited by the restriction of installing space and cost, generally only be used in the large excavator more than 40 tonnes, middle-size and small-size hydraulic shovel rarely has use.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of hydraulic excavator radiating fan driving device, has realized the controllability of rotation speed of the fan under existing installing space.
To achieve these goals, the technical solution adopted in the utility model is: a kind of hydraulic shovel fan drive device, the silicon oil clutch that comprises flange and temperature transducer is installed, temperature transducer is electrically connected to the Engine ECU control unit, one end connecting engine fan pulley of flange, the other end and silicon oil clutch are connected, and fan is bolted on silicon oil clutch.
Described flange is connected with internal thread on silicon oil clutch by outside thread.
The beneficial effects of the utility model are: by the cooperation between silicon oil clutch, temperature transducer and Engine ECU control unit, under the prerequisite that does not change installing space, realize the adjusting of rotation speed of the fan, keep the thermal equilibrium of complete machine.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structure enlarged diagram of flange shaft in the utility model;
Fig. 3 is the structure enlarged diagram of silicon oil clutch in the utility model.
In figure: 1, silicon oil clutch, 2, flange, 3, fan, 4, outside thread, 5, internal thread.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3: the silicon oil clutch 1 that the utility model comprises flange 2 and temperature transducer is installed, temperature transducer is electrically connected to the Engine ECU control unit, one end connecting engine fan pulley of flange 2, the other end and silicon oil clutch 1 are connected, and fan 3 is bolted on silicon oil clutch 1.
Described flange 2 is connected with internal thread 5 on silicon oil clutch 1 by outside thread 4.
In the utility model, increase the silicon oil clutch with temperature transducer between the fan 3 that is used for heat radiation and fan pulley, temperature transducer detects the temperature by the air after the fan 3 that is used for heat radiation, signal is passed to the Engine ECU control unit, result by the calculating of ECU control unit, regulate silicon oil clutch 1 engagement, thereby automatically adjust fan 3 rotating speeds.
The characteristic of silicon oil clutch 1 has realized that under low temperature environment, silicon oil clutch 1 separates, and fan 3 rotating speeds are low, make as early as possible complete machine reach optimum working temperature; After temperature rose, silicon oil clutch 1 was closed gradually, and fan 3 rotating speeds progressively improve; After reaching uniform temperature, silicon oil clutch 1 is fully closed, has realized the constant ratio of fan 3 rotating speeds with engine speed, thereby keeps the thermal equilibrium of complete machine.
