Title:
FLOW CONTROL DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/174620
Kind Code:
A1
Abstract:
A front flow-control section (34) is formed at the front section of a main section (32) of a spats (30), and a front inclined surface (36) is, in side view, inclined towards the rear side of a vehicle while going towards the bottom of the vehicle, and front side surfaces (38) extend towards the vehicle front side from vehicle width direction end-sections (36A) of the front inclined surface (36). A travelling wind (F3) which struck the front side surface (38) flows towards the front inclined surface (36) side and then together with a travelling wind (F2) flows out from the front flow-control section (34) to the bottom of the vehicle, and therefore the flow speed of the travelling winds (F2, F3) becomes faster. Due to this configuration, the contact of travelling winds (F2, F3) with a tire (12) and the like can be suppressed, and the air resistance of the vehicle can be reduced. Further, because the flow speed of travelling winds (F2, F3) becomes faster an ascending force acts on the vehicle, and because the ascending force and gravity cancel each other, vehicle steering stability is improved. Also, because fluctuation of the vehicle in the vertical direction is suppressed due to ascending force, the riding comfort performance of the vehicle is improved.
