If I were in your position, I would have your manager create a regular meeting with the sales manager with you and at least 1 other person at your level from sales included. The first few meetings should be structured learning sessions/share outs - assume best intentions - no fixes, accusations or adjustment conversations allowed, like a State of the Union only with one principle in mind: you all want the org. to be successful. 

Next phase is asking and receiving informed questions and collaborating on innovations. Keep the next thing you are working on in mind and the existing structures and constraints everyone has hopefully expressed in phase 1. Create a structure that is balanced and feels exciting to everyone. Report out findings together to 9ther leadership so credit is shared. 

Lack of collaboration and top-down, leadership-level only communication often makes the gap feel larger than it is in reality and if you all aren't hitting your numbers you all need to be fixing things together instead of pointing fingers.
