Project
- The CVT is located in car model as shown in imaeg below
- The working of CVT is as follows
A CVT module working is as follows:
A CVT works on principle of movement of pulleys in both inward and outward to control the speed.
When primary pulley moves outward and secondary pulley moves inward (Rs > Rp) speed is reduces.
When primary pulley moves inward and secondary pulley moves outward (Rp > Rs) speed is increased.
- There are two types of CVT connections:
Depending on the connecion of vehicle body with the with CVT is divided into two types
A) Open Loop B)Closed Loop
A)For open loop connection we have two models
Inside CVT model
Inside vehicle mode
CVT ratio
1) CVT Model Dashboard:
CVT primary and secondary is:
Result of the model is follows:
Velocity, Distance, Throttle Brake
CVT primary and secondary is:
2) CVT Model:
As can see in the block above instead of two separate brake and throttle inputs we are using a signal builder block for both units. And have removed dashboard from the module
The CVT primary and secondary as seen in scope:
The output changes in scope:
Velocity, Distance, Throttle, Brake
B) For Closed Loop system we have four models
CVT model inside
Vehicle Modelling
1) CVT Model Data
Inputs Brake and Throttle
CVT Ratio
CVT Primary and Secondary
The output of Scope
Vehicle Speed, Throttle, Time
Result: From the above models we studied open loop and closed loop configuration of CVT BAJA Engine for ATV
2) CVT model dashboard mapped
CVT Ratio
CVT Primary & Secondary
The Scope output
Vehicle Speed, Throttle, Time
