I have been working on the development of a manual transmission simulation model, in the physical system modeling tool (Simscape and Simdriveline), by implementing a synchromesh unit consisting of a cone clutch and a dog clutch.
An important parameter which needs to be configured for the Dog Clutch model is the number of teeth. While the usual practice is to simply count them on the transmission unit being modeled and use the same number.
However, there may be a scenario when we don't have a physical unit for reference and the parameter needs to be estimated. In order to achieve close to actual results, this estimate must be as close as possible to the the actual parameter.
Therefore, if there is any way in which this parameter can be "designed", it would be best way to estimate the same.
Please drop your answers on how to decide or design "number of teeth" for a dog clutch..
The number of teeths in a dog clutch is mainly influenced by two factors:
- effort for production: the higher the number of teeths, the higher the costs
- Shifting quality / time: the higher the number of teeths, the better shifting quality, because of reduced angular position requirements.
Due to centric running of the system, minimum 3 teeths should be provided. In general, teeth numbers between 4 and 8 occur. Teeth numbers with significantly higher numbers are appliet in the so-called Hirth-Clutch (for non-shiftable, or static-shiftable applications):
