2010 Vauxhall Astra에서 1단, 2단 기어에 진입할 때 물리적으로 막히는 느낌이 남. 기어 스틱의 트리거(보통 후진에 사용)를 들어올리면 1단, 2단에는 진입 가능하지만 후진 기어를 찾을 수 없음.

2003 올즈모빌 알레로가 55mph에서 약 4000rpm, 70mph에서 거의 5000rpm으로 회전합니다. 정상이 아닌 것 같습니다. 트랜스미션이 제대로 시프트되지 않는 건가요? 트랜스미션에 특별한 문제는 느껴지지 않습니다. 이것이 간단히 해결할 수 있는 문제인지, 아니면 더 심각한 문제인지 모르겠습니다.

My 2018 Subaru Legacy 3.6R has a CVT, and I have wondered why it is programmed to change ratios in discrete steps (like a conventional automatic transmission would) rather than varying continuously. I see a couple possibilities in the comments and answers to this prior question: CVT on 6 cylinder cars If the ratio varies continuously, it feels and sounds odd to a driver used to conventional transmissions ("like a car with a slipping clutch"). There's greater wear on the transmission during ratio changes, so limiting the frequency of changes improves reliability. Is it likely one of t

I need to make some gears/pinions myself. I have access to a high quality 4-axis CNC mill, but not to a lathe. I'd like to cut these gears out of flat stock (facing), rather than round (edgewise) using narrow end mills. Being able to prototype this in plastic sheets is important to me. I've found a bunch of sites that explain hobbing and that have formulas for pitch etc, but no sites that actually generate the splines for the gear teeth to turn into Gcode. Before I sit down with Mathematica and derive it from first principles, does anyone know of a good resource for this?
