Technical field
The present invention relates to a kind of pilot system of testing automobile performance, relate in particular to a kind of wind-tunnel fast braking pilot system.
Background technology
Referring to Fig. 1; Fig. 2; Wind-tunnel fast braking pilot system of the prior art comprises air door control system, air quantity control system, blower fan 1, plenum chamber 2, main air duct 3 and movable air door 4, and said air door control system is connected with plenum chamber 2 with air quantity control system respectively, and said air quantity control system also is connected with blower fan 1; Blower fan 1, plenum chamber 2 and main air duct 3 set gradually and form a gas channel, and movable air door 4 is arranged on the air outlet of main air duct 3.When carrying out the test of automobile fast braking; Be placed on automobile in the place ahead in movable air channel 4; The air-flow measured that is produced by blower fan 1 directly acts on test vehicle; When simulation test reaches automobile quick closedown activity air door 4 behind state under the high-speed cruising, the influence that is brought with simulating vehicle brake hard when running at high speed.Referring to Fig. 3; Because in the process that movable air door 4 is closed; Movable air door 4 will bear the blast (direction of arrow is airflow direction) of huge horizontal direction, is prone to cause the accident, and makes the safety coefficient of whole wind-tunnel fast braking pilot system low; All need the position of adjusting activity air door again, complex operation when changing the vehicle of testing at every turn.
Summary of the invention
The present invention is intended to overcome the deficiency of above prior art, and a kind of safe wind-tunnel fast braking pilot system is provided.
Technical solution problem of the present invention adopts following technical scheme:
A kind of wind-tunnel fast braking pilot system; Said wind-tunnel fast braking system places in the lab space; Said wind-tunnel fast braking system comprises air door control system, air quantity control system, blower fan, plenum chamber, main air duct and movable air door; Said air door control system is connected with plenum chamber with air quantity control system respectively, the aperture of the pressure control wind blocking door through control air quantity control system and plenum chamber, and said air quantity control system also is connected with blower fan; To regulate the airshed of blower fan; Said blower fan, plenum chamber and main air duct set gradually and form a gas channel, and be characterized in: said wind-tunnel fast braking pilot system also comprises the inferior air channel that is communicated with plenum chamber, and the air outlet in said air channel is provided with the wind deflector that is communicated with time air channel and lab space; So that import the air-flow in time air channel in the main air duct; Normal air flow in the simulated air, said movable air door is arranged in the plenum chamber, in plenum chamber, also is provided with the support governor motion of support and adjusting activity damper positions; The air outlet of said main air duct is provided with blast regulator, to regulate the airshed in movable air channel.
Further, said support governor motion is a piston cylinder.
Further, bump against in order to prevent movable air door and plenum chamber floor, the joint, floor of movable air door and plenum chamber is provided with anti-collision block in said plenum chamber.
Beneficial effect of the present invention is following:
Movable air door is arranged in the plenum chamber, and the cylinder of adjusting activity damper positions is set in plenum chamber, this wind-tunnel fast braking pilot system also is provided with the inferior air channel that communicates with plenum chamber.When simulated automotive high-speed cruising pattern, cylinder withstands movable air door and blocks time air channel, and air communication crosses plenum chamber and movable air channel acts on the automobile that is placed in the test space of opposite, movable air channel; When the simulated automotive braking mode; Block the passage that plenum chamber leads to main air duct through the tenesmus of cylinder drive activity air door, air-flow gets into time air channel, has reduced the suffered pressure of movable air door; Security improves greatly; And the air communication that imports time air channel is crossed wind deflector and is imported in the test space, so that normal air-flow to be arranged in the warranty test space, has simulated normal air flow in the car running process.In addition,, also need not to regulate the position of deep bead even change when testing vehicle, simple to operation.
