Abstract
The utility model relates to an automobile choke device, which can effectively improve aerodynamic performance of an automobile choke plate. The technical scheme includes that a front choke plate is installed at the front end on the bottom portion of an automobile body. The automobile choke device is characterized in that the front choke plate tilts backwards.
Description
Technical field
The utility model relates to a kind of automobile choke device.
Background technology
The effect of automobile choke plate mainly is friction force and the air turbulence that reduces bottom air-flow and chassis, to reduce the car load air resistance coefficient; Reduce front-wheel lift, improve road-holding property.When car was run at high speed, road-holding property and oil consumption were two and need most top-priority performance.For car, front-wheel lift is crossed senior general and is caused that pitching moment increases, and causes wafing at the situation of the running at high speed hair of getting off, and it is very big to drive danger.During high speed, it is a lot of that bigger air resistance coefficient can make the high speed oil consumption increase.The height parameter of choke plate is very crucial, hangs down the effect that do not have excessively, and the too high aeroperformance that then can make on the contrary worsens.
In the prior art, domestic car seldom has and installs this annex of choke plate additional, and external choke plate that vehicle adds generally all is vertical setting, and vertical choke plate will make the body structure malleation sharply increase, very easily additionally increase the machinery space suction quantity, air resistance coefficient is increased.
The utility model content
Goal of the invention of the present utility model is to provide a kind of automobile choke device, can effectively improve the aerodynamic performance of automobile choke plate.
Realize the technical scheme of the present utility model purpose:
A kind of automobile choke device is equipped with air dam skirt at the front end of body bottom, and it is characterized in that: air dam skirt recedes.
The angle of air dam skirt dip plane and vertical direction is the 15-25 degree.
The angle of air dam skirt dip plane and vertical direction can be 18 degree.
Air dam skirt is by being bolted to the bottom of vehicle body water tank cross sill, and is provided with reinforced rib on air dam skirt.
In car cover bottom, the front of corresponding tire is provided with the tire choke plate.
The height of tire choke plate is 47-52mm.
The height of tire choke plate can be 50mm.
The beneficial effect that the utlity model has:
Air dam skirt of the present invention is designed to the certain angle that recedes, when guaranteeing to reduce bottom air-flow and the friction of body bottom spare and reducing front-wheel lift, and the big risk of air resistance coefficient change that can also effectively reduce even avoid too much causing because of the front end air inlet.The tire choke plate can effectively reduce near turbulent flow and the disturbance the tire, and air dam skirt and tire choke plate are used in combination, and can further effectively reduce air resistance coefficient, reduces front-wheel lift, thereby obtains better aerodynamic performance.
Description of drawings
Fig. 1 is the perspective view of the utility model air dam skirt;
Fig. 2 is the front view of the utility model air dam skirt;
Fig. 3 is the birds-eye view of the utility model air dam skirt;
Fig. 4 is the installation site scheme drawing of the utility model on car load.
The specific embodiment
As shown in Figure 4, at the front end of body bottom air dam skirt 1 is housed, air dam skirt recedes, and the angle of air dam skirt dip plane and vertical direction is the 15-25 degree, and in the present embodiment, preferred angle is 18 degree, and the vertical direction height of air dam skirt is 80 to 100mm.
As Figure 1-3, for the consideration of installing, air dam skirt left side 1/4th places bending is stepped, air dam skirt is provided with bolt hole 3, air dam skirt is by being bolted to the bottom of vehicle body water tank cross sill, and on air dam skirt, be provided with reinforced rib 4, to improve the intensity of air dam skirt, avoid its chatter even come off under the impact of height air-flow.
As shown in Figure 4, in car cover bottom, the front of corresponding tire is provided with tire choke plate 2, and four-wheel tire choke plate is the rectangular plate shell-like structure, and the front-wheel choke plate can be made of one structure with the plastics front bumper, and the trailing wheel choke plate is captiveed joint with the wheel cover lower end.The height of tire choke plate is 47-52mm, and in the present embodiment, preferred heights is 50mm, and the length of tire choke plate is 200mm, and the outermost distance of tire choke plate outer face and wheel cover remains on about 45mm.
Sweptback air dam skirt cooperates the four-wheel tire choke plate of preferred heights, both rectifiable bottom air-flows, reduce the friction of bottom air-flow and bottom parts, improve the tail wind fluidised form, also can reduce front-wheel lift, reduce pitching moment and obtain better road-holding property, simultaneously, also can avoid the front end air inlet excessive, when guaranteeing capacity cooling air inlet, further reduce air resistance in the cabin.Emulation and test results show: after the air dam skirt of hypsokinesis 18 degree being installed and highly being the tire choke plate of 50mm, pneumatic drag coefficient, pitching moment coefficient all are significantly improved, and lift coefficient also is controlled at preferably in the scope.
Another preferred embodiment of the present utility model: the angle of air dam skirt dip plane and vertical direction is 20 degree, and the height of tire choke plate is 51mm.
