Abstract
At least two cooling air inlet apertures(6, 8), one(8)of which is exposed by means of a flap(9)utilising the pressure ratio in the cooling air duct(5)and in the airstream flow only at low speeds, are assigned to an engine radiator(3)with fan(4).
Description
The present invention relates to a kind of cooling mechanism that is used for the drive motor of power actuated vehicle, the cooling mechanism that this class is only just opened the coolant air sucking hole when needed is open with various quoting method by No. the 2322661st, US Patent and No. 4429666.Under any circumstance, sucking hole to open or close be that the temperature that is decided by cooling water expansion tank realizes by valve.The temperature of cooling water expansion tank is surveyed with a kind of sensor, and signal of sensor is converted to an appropriate motion of valve by pull bar.Belong to the technical merit aspect and also have ventilator, the temperature of cooling water expansion tank when low speed driving or driving motor stop to be depended in its connection.
From reducing the vehicle airflow resistance also is the Cw value, the sucking hole of closing coolant air by valve has special significance as mentioned above, car body the is suffered relative wind " smoothly " that travels, that is the quantity of coolant air sucking hole is few more, then the air resistance of automobile is also more little, particularly fuel consumes in a large number when the higher speed of a motor vehicle, therefore finally also aggravates the pollution to environment.
In this respect, the aluminium cooling vessel of closs packing soldering is particularly advantageous.Because the automobile of this cooling vessel of equipment is when running at high speed, the efficient that reaches enough coolings is very high, and this cooling vessel can be done quite for a short time, and the cross section of air suctiton inlet is also very little, and the Cw value that is caused by coolant air also only improves little by little.Yet, as pointing out already, when adopting this novel cooling vessel, especially then too little as the suction cross section of the vehicle coolant air of running at high speed, if when low speed driving, high load capacity appears in electrical motor, for example last be exactly this situation when travelling.When such low speed, the air resistance of automobile does not have noticeable disadvantage.
Task of the present invention is to provide a kind of cooling mechanism that is used for the drive motor of power actuated vehicle, under the situation of avoiding serviceability temperature sensor and valve control operating rod, handles valve energy and makes the Automobile air flow resistance that is caused by cooling mechanism reduce to minimum degree.
The present invention includes a coller for motor, ventilator that cooperates with cooling vessel and one sustainable that open with one utilize automatic guidance to be arranged in partly closable coolant air sucking hole of coller for motor and ventilator fwd car body; When it is characterized in that galloping, for enough cooling air deliverys are provided, sucking hole is continuable to be opened, than the top load low speed driving time, connect ventilator, the rarefied air of the coolant air that produces when valve will be settled to such an extent that work by ventilator can move in its sucking hole.Feature of the present invention, is regulated the low pressure of car body part, but is made valve be tending towards closing direction when running at high speed being that also the body portions branch is equipped with valve; Valve in the valve off position is supported on the retainer by action of gravity; Its sucking hole support spring is housed on the valve.
The present invention regulates different rate of supercharginges in an advantageous manner and handles valve.In two kinds of situation, when galloping, close ventilator and stream by the air of automobile and cause low pressure or rarefaction of air, and when the automobile low speed driving, the shell of vehicle makes by the ventilator of connecting and cause rarefaction of air in cooling air channels near barometric pressure.Therefore, any control operating rod or the similar mechanism that promotes valve just become unnecessary.
Described in claim 3 and 4, make full use of valve weight and (or) spring that adds controls the motion of valve.
Below in conjunction with accompanying drawing narration embodiments of the invention.
Description of drawings:
State when Fig. 1 is galloping;
Fig. 2 is the position longitudinal profile scheme drawing of automobile low speed (for example going up to travelling) valve and air current flow during by crooked location.
The electrical motor cabinet 2 of automobile is arranged in the air flow direction of the back of general cooling vessel grille 1; Except that cooling vessel 3, this electrical motor does not mark on accompanying drawing.As everyone knows, ventilator 4 is in the back of cooling vessel, so further do not provide structure on the figure, can connect when needs.
Coolant air guiding device 5 with sucking hole 6 of opening constantly is arranged in cooling vessel 3 fwd air flow lines, and the arrow indication is a coolant air.In its lower section, another cooling air channels 7 is arranged, above the sucking hole 8, the direction on moving traffic lane can communicate with extraneous air substantially at another for it, and valve 9 is arranged side by side with sucking hole 8, and by transverse axis 10 supportings and can be around transverse axis 10 rotations.Sucking hole 8 and valve 9 exist together in the zone, when galloping, can regulate low pressure in this zone.
If at first consider the situation of galloping shown in Figure 1, then ventilator 4 is closed, valve 9 is in closed condition, valve keeps closing with the low pressure of its deadweight and outside in this state, valve 9 is on the retainer 11, during low speed driving (Fig. 2), ventilator 4 is switched on, because the dynamic head that cooling vessel 3 is ventilated is not enough.The air of automobile streams in valve 9 zones.It is not enough so that the valve that is under the closed condition keeps low pressure to the rarefied air that is produced by ventilator 4.As shown in Figure 2, thus valve 9 be transferred to open position 9 '.Spring is placed on the valve so that fixing.
Therefore, guaranteed that automobile the air resistance of adverse effect only occurs owing to only opening the value that quite little coolant air sucking hole 6 has minimum when needed when running at high speed, when needs, be that automobile is during with low speed driving, automatically utilize rate of supercharging, that is, another air suctiton inlet 8 is opened avoiding pull bar to handle under the similar operating condition with other.
In fact, when galloping, promptly be in the work of barrier effect, it is quite little that air sucks the cross section, on the contrary when connecting ventilator, promptly be in the suction work, it is quite big that air sucks the cross section, in both cases, the above-mentioned fact is all given the best ratio that flows into: in the work of barrier effect, be between sucking hole and the cold wind device buffering to be arranged, and in another case, coolant air quickened.
Claims (4)
1, a kind of cooling mechanism that is used for the driving motor of power actuated vehicle, it comprises a coller for motor, ventilator that cooperates with cooling vessel and one sustainable that open with one utilize automatic guidance to be arranged in coller for motor and the closable coolant air sucking hole of ventilator fwd car body part, when it is characterized in that galloping, for enough cooling air deliverys are provided, sucking hole 6 is opened sustainably, than the top load low speed driving time, connect ventilator 4, the rarefied air of the coolant air that valve 9 is produced in the time of will settling to such an extent that work by means of ventilator can move in its sucking hole 9.
