When I read in the literature "constant mesh trasmission" - what is that and what is the benefit?

Thanks,
Bill

When I was interested in cars in my youth, I was came to believe that constant mesh gears referred to helically cut gears that, due to the fact that they would slide along each other's teeth, would be constantly meshed. They would therefore not make the whining noise that older cars would make in low gear, and that cars with standard transmission will still make in reverse. Maybe this is a different kind of constant mesh, or maybe I am thinking of another term altogether. Does anyone else remember the term used this way?

It's worth noting that virtually all modern transmissions are constant mesh, so it doesn't mean a lot if one brand says it has a constant mesh transmission and another doesn't.

Synchronized gears (or "synchro-mesh") is entirely another thing.

Constant mesh means that the primary driving gears are always in mesh with each other, they never move out of their respective positions. This prevents them from damage due to clashing or partial engagement. However, some way still has to be provided for the power flow to be connected or disconnected. This is done with shift collars, which mate up with "dog teeth" which are an integral part of a primary gear. So in effect, there still is tooth engagement and disengagement going on inside, it's just with much smaller length teeth as compared to the main gear. If the trans is not syncronized, there is still the possibility of "gear clash", although it's not the main gear teeth that are making the noise, but rather the dog teeth.

One thing to remember is that gears have teeth for one main reason, that is to engage with the teeth of one or more other gears. In this way things are set in motion. Constant mesh simply means that the gears teeth are continuously engaged with the teeth of the adjoining gear or gears that are it's running mate. BENEFITS: No grinding of gears as you change from one speed to another. No partial engagements under load. Sometimes this can have disasterious results. Dan Robertson
