Narrative:

During a flaps 3 reduced power takeoff on ord runway 22L at approximately 500 AGL; we hit suspected wake turbulence from the preceding airbus. We had been cleared for takeoff immediately after the airbus had taken off. First officer flew the aircraft through the turbulence with noticeable wing rock and chop. At approximately 700-900 ft; we reencountered a second wake turbulence event. ATC directed a turn towards a westerly heading. PF lowered aircraft nose due to turbulence at which time we exceeded flap 3 limiting speed. The overspeed bell came on and speed tape indicated an overspeed condition. I called out overspeed and advised PF to increase pitch. Due to the wake turbulence he was busy flying the aircraft. I raised the flap handle to flaps 1 and the warnings went away. Rest of flight was uneventful. A maintenance report was sent to maintenance for the overspeed.we debriefed our actions. Emphasis on threat awareness of taking off immediately after another aircraft with strong and turbulent headwinds winds that were present. I should have reviewed and discussed that threat prior to takeoff. We were late for our expected departure clearance time delay to ZZZ and aircraft traffic for takeoff was backed up. In the future I will ensure I include this threat in my departure briefs.

Title: A320 flight crew reported a wake turbulence encounter with an Airbus on departure from ORD Runway 22L resulting in a flap overspeed.

Narrative: During a flaps 3 reduced power takeoff on ORD Runway 22L at approximately 500 AGL; we hit suspected wake turbulence from the preceding Airbus. We had been cleared for takeoff immediately after the Airbus had taken off. FO flew the aircraft through the turbulence with noticeable wing rock and chop. At approximately 700-900 ft; we reencountered a second wake turbulence event. ATC directed a turn towards a westerly heading. PF lowered aircraft nose due to turbulence at which time we exceeded Flap 3 limiting speed. The overspeed bell came on and speed tape indicated an overspeed condition. I called out overspeed and advised PF to increase pitch. Due to the wake turbulence he was busy flying the aircraft. I raised the flap handle to Flaps 1 and the warnings went away. Rest of flight was uneventful. A Maintenance Report was sent to Maintenance for the overspeed.We debriefed our actions.
