Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
The present invention provides a kind of motor front-end wheel system durability test apparatus, as depicted in figs. 1 and 2, the motor head Train durability test apparatus includes space 1, heat exchanger 2, heater 3, connecting shaft 4, fan 5 and cooling water tank 6, wherein:
Above-mentioned space 1 is closed or semi-hermetic structure, and the front end wheel train of engine is placed in the space 1, specifically, this reality The above-mentioned motor front-end wheel system durability test apparatus for applying example has further included baffle 7, and the housing of the baffle 7 and engine is (before i.e. Hold train at shell or other component housing, be not shown in figure) between form above-mentioned space 1.In the present embodiment, preferably will Space 1 is set as totally-enclosed structure, to prevent heat losses, is unfavorable for the heating to front end wheel train.It is contemplated that front end is taken turns The style characteristic of system, it is desirable to all seal in space 1, the cost needed is excessively high, therefore, can space 1 be set as semi-hermetic Structure, that is, as long as it can ensure that the temperature of front end wheel train is increased to experiment required temperature (95 ± 5 DEG C), permission space 1 There are portion voids.
In the present embodiment, Fig. 1, above-mentioned 7 U-shaped structure of baffle, in order to connect with the respective housings of engine can refer to It connects.
In the present embodiment, above-mentioned front end wheel train includes belt pulley 8 (shown in Fig. 1), and above-mentioned belt pulley 8 is arranged on above-mentioned sky Between in 1, it should be pointed out that the front end wheel train of the present embodiment is not limited only to belt pulley 8, further includes such as motor head Gear, other belt wheels etc., here, only showing belt pulley 8.
As shown in Figure 1, above-mentioned heat exchanger 2 and heater 3 are arranged in above-mentioned space 1, and positioned at belt pulley 8 and gear Between plate 7.Above-mentioned heat exchanger 2 goes out water return pipeline (not shown) with the warm wind of engine and connect, setting with this configuration It puts, the heat that engine can be utilized to generate in itself, i.e. the hot water of engine outflow can be by heat exchanger 2 and space 1 Air carry out heat exchange, and then the air themperature in room for promotion 1, the air in subsequent space 1 can be to front end wheel train It is heated.
In view of by the heat of engine itself, front end wheel train only can not be heated to experiment required temperature, this Setting heater 3, the heater 3 are connected to controller (not shown) to embodiment also in space 1, can be further to preceding End train is heated, and since space 1 is closed or semi-hermetic structure, front end wheel train can be ensured by heat exchanger 2 and heating Device 3 is heated to experiment required temperature.In the present embodiment, above-mentioned heater 3 can be heating tape or heater strip or its The structure of his such as heating tube or heating dish, can be around being located on heat exchanger 2 when for heating tape or heater strip.When When for heating tube or heating dish, the side of 2 face belt pulley 8 of heat exchanger is may be mounted at, sky can also be mounted on Between 1 other component on.In the present embodiment, heater 3 is preferably heating tape or heater strip.
Specifically, as shown in Fig. 2, the above-mentioned heat exchanger 2 of the present embodiment includes heat-exchange tube, the both ends of the heat-exchange tube The warm wind for being connected to engine goes out water return pipeline.The above-mentioned serpentine-like structure of heat-exchange tube, and the front end wheel of face engine System's setting, by the setting of serpentine configuration, enables to heat exchange of the engine warm wind return water at heat exchanger 2 more thorough, Further improve the heat utilization ratio of engine.When above-mentioned heater 3 is heating tape or heater strip, it is set around part heat exchange On pipe or whole heat-exchange tubes, positioning is supported by heat-exchange tube.
It should be noted that above-mentioned heat-exchange tube can also be the structure of other shapes, for example, the distribution shape of heat-exchange tube Shape can be identical with the distribution shape of the front end wheel train of engine, and then targetedly front end wheel train can be heated.
The above-mentioned heat-exchange tube of the present embodiment is made of brass material, to reach higher rate of heat exchange.
As shown in Figure 1, the front end wheel train that above-mentioned 4 one end of connecting shaft is connected to engine (is specifically connected to belt pulley 8 Center position), the other end passes through space 1 and is connected to said fans 5.It is sent out in view of 2 face of heat exchanger of the present embodiment The front end wheel train setting of motivation, therefore, above-mentioned connecting shaft 4 can also pass through heat exchanger 2.
Side of the said fans 5 far from the space 1 is additionally provided with cooling water tank 6, can by fan 5 and cooling water tank 6 Resistance environment when simulated engine is run so that the long duration test of motor front-end wheel system is more bonded real scene, so as to Obtain more accurately test data.It should be pointed out that the fan 5 of the present embodiment is arranged on one of baffle 7 far from heat exchanger 2 Side, and then when fan 5 is run, the wind of blowout can be blocked by baffle 7, and be flowed out from 7 both sides of baffle, can effectively avoid wind 5 pairs of 1 internal temperatures of space of fan influence too much, and cause front end wheel train temperature that happening for test temperature is not achieved.
In the present embodiment, it is preferred that the motor front-end wheel system durability test apparatus of the present embodiment is additionally provided with temperature biography Sensor (not shown), the temperature sensor can detect the temperature of the front end wheel train of engine and feed back the temperature in control Device, controller then by the heated condition of the temperature controller heater 3 received (such as heater 3 is opened and closed or Adjustment of heating power etc. is carried out to heater 3), more accurately to adjust the temperature at front end wheel train.Preferably, this implementation The above-mentioned temperature sensor of example is arranged in space 1, more accurately to detect the temperature at front end wheel train.
The above-mentioned motor front-end wheel system durability test apparatus of the present embodiment, without the mating experiment with function of temperature control Between, the manufacture cost of test bay can be reduced, and be transformed without to the test bay for not having function of temperature control.When using During motor front-end wheel system durability test apparatus, the temperature at front end wheel train need to be only detected in real time by temperature sensor, and lead to The time that controller is opened according to the temperature control heater 3 is spent, by heater 3 and heat exchanger 2 jointly to front end wheel train Heat temperature raising is carried out, the temperature at front end wheel train is enabled to reach 95 ± 5 DEG C, to meet long duration test process to front end wheel train The validity of examination, it is at low cost and easily fabricated.And the setting of the heat exchanger 2 of the present embodiment, it can efficiently use and start The heat that machine generates in itself, further reduced experimentation cost.
Obviously, the above embodiment of the present invention is just for the sake of clearly illustrating example of the present invention, and it is pair to be not The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this All any modification, equivalent and improvement made within the spirit and principle of invention etc., should be included in the claims in the present invention Protection domain within.
