Abstract
The utility model discloses a cooling fan assembly for a chassis dynamometer. The cooling fan assembly solves the problems that existing cooling fans are poor in stability and inconvenient to move. The cooling fan assembly comprises a cooling fan, two pairs of flat plate type universal wheels are fixedly connected below the cooling fan, and jacking devices for jacking up the universal wheels are arranged below support flat plates in the flat plate type universal wheels. Each jacking device comprises a scissor jack and a jacking flat plate, the jacking flat plate is fixedly connected with the upper surface of a jacking contact in the scissor jack, the top surface of the jacking flat plate is contacted with the bottom surfaces of the support flat plates positioned on the flat plate type universal wheels, and the jacking flat plate is fixedly connected with the upper surface of the jacking contact in the scissor jack through a bolt. The cooling fan assembly has the advantages of being good in stability, capable of sliding in any direction, time-saving and labor-saving during movement, extremely convenient, capable of adapting to heights of different vehicle types and simple in structure and the like.
Description
Technical field
The utility model relates to the car performance test system field, especially relates to a kind of cooling blower assembly of chassis dynamometer.
Background technology
Chassis dynamometer can detect by the method for the simulated roadway driving cycle of getting on the car at indoor stand the various performances of automobile, can also measure multi-state discharge index and oil consumption etc.At present when using chassis dynamometer to test, but the cooling blower on the chassis dynamometer system comes spacing by the locking universal wheel that is positioned at the cooling blower lower end, being about to cooling blower is pushed into after the correct position, by self lockable mechanism on the universal wheel with the universal wheel locking, thereby reach the purpose that prevents that cooling blower is subjected to displacement.But but the surface of contact of locking universal wheel and bottom surface is less, friction force between the two is less, poor stability, if the wind-force that cooling blower produces is excessive, can cause cooling blower mobile backward, can break the facility of blower fan back when serious, there is potential safety hazard, but the lockable mechanism of locking universal wheel self is firm not, and less stable is damaged in the situation of long-time locking easily.
In addition, Chinese patent Granted publication number: CN201532311U, July 21 2010 Granted publication day, a kind of air duct telescoping mechanism for the chassis dynamometer vehicle cooling is disclosed, comprise underframe, drive motor and be installed in cooling blower on the underframe, described underframe upside is provided with support, on this support drive motor is installed, described drive motor power output shaft is connected with the cooling blower main shaft, described cooling blower air outlet is connected with fixing air duct one end, and the described fixedly air duct other end is connected with telescopic movable air duct.Its weak point is that this cooling blower is to place on the ground by underframe, and is mobile very inconvenient.
The utility model content
The utility model is in order to solve existing cooling blower poor stability, to move the problem of inconvenience, providing a kind of conveniently moving and good stability, the cooling blower assembly of chassis dynamometer simple in structure.
To achieve these goals, the utility model is by the following technical solutions:
A kind of cooling blower assembly of chassis dynamometer comprises cooling blower, and described cooling blower below is fixedly connected with two pairs of flat universal wheels, and the support plate below in the described flat universal wheel is equipped with the jacking apparatus for the jack-up universal wheel.Cooling blower below in the utility model is fixedly connected with two pairs of flat universal wheels, adopt two pairs of flat universal wheels to support cooling blower, not only so that in the past any direction slip of cooling blower, and mobile time saving and energy saving, good stability during support, after blower fan to be cooled moves to correct position, can also guarantee simultaneously with jacking apparatus reposefully with flat universal wheel jack-up, make universal wheel built on stilts, cooling blower just can not move like this, stability also is greatly enhanced during use, and jacking apparatus can make cooling blower be in differing heights by lifting, thereby makes cooling blower can adapt to the height of different automobile types.
As preferably, described jacking apparatus comprises that scissor-like jack and jacking are dull and stereotyped, and the contact upper surface is lifted on the top that described jacking flat board is fixedly connected in the scissor-like jack, and the dull and stereotyped end face of jacking contacts with support plate bottom surface on the flat universal wheel.The jacking flat board can increase and flat universal wheel in contact area between the support plate, so not only so that support plate is stressed more even, the jacking process is more steady, but also can improve friction force between jacking flat board and the support plate, so that be difficult between support plate and the jacking flat board relative sliding occurs, greatly improve the stability of cooling blower.
As preferably, described jacking dull and stereotyped with scissor-like jack in the top lift contact and be bolted to connection.
Be bolted, strength of joint is good, and dismounting is also very convenient.
Therefore, the utlity model has following beneficial effect:
(1) good stability;
(2) any direction is slided in the past, and is mobile time saving and energy saving, very convenient;
(3) can adapt to the height of different automobile types;
(4) simple in structure.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Among the figure: cooling blower 1, flat universal wheel 2, support plate 3, scissor-like jack 4, contact 5, jacking flat board 6 are lifted in the top.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Among the embodiment as shown in Figure 1 and Figure 2, a kind of cooling blower assembly of chassis dynamometer, comprise cooling blower 1, scissor-like jack 4 and two pairs of flat universal wheels 2, support plate 3 in the flat universal wheel 2 is bolted on the bottom of cooling blower 1, and the two pairs of flat universal wheels 2 are fixed on the bottom of cooling blower 1 before and after respectively, contact 5 upper surfaces are lifted on the top that jacking flat board 6 is bolted in the scissor-like jack 4, and dull and stereotyped 6 end faces of jacking contact with support plate 3 bottom surfaces in the flat universal wheel 2.
During use, promote cooling blower 1, by flat universal wheel 2 cooling blower 1 is moved to suitable working position, then respectively place a scissor-like jack 4 in flat universal wheel 2 one sides, the top that raises is lifted contact 5 jacking dull and stereotyped 6 is contacted with support plate 3 bottom surfaces in the flat universal wheel 2, the then working depth required according to cooling blower 1, raise the simultaneously top of each scissor-like jack 4 is lifted contact 5 and is made simultaneously jack-up slowly of two pairs of flat universal wheels 2, until cooling blower 1 rise to required working depth, cooling blower 1 was not maked somebody a mere figurehead and can arbitrarily be moved this moment; After the use, contact 5 is lifted on the top that descends simultaneously, flat universal wheel 2 is landed after, take scissor-like jack 4 away, cooling blower 1 is just removable again.
