What is the name of a childhood anime/cartoon i once favored when i was 7 years of age?

I do not know whether is is an anime or cartoon because the channel i watched on only shows dubbed cartoons.
Here are the details

-Its a robot-based show
-The only robots i could remember are three of them - One was a police themed robot , Another one is an ambulance themed robot and the last one i could remember is a firetruck themed robot.

-Each robot is made up of 1 main robot and 4 smaller ones( all of which could turn into vehicles ( police car , ambulance and firetruck respectively))

-these 5 robots would combine into one awesome , cool-looking robots. The main bot will be the torso and the head while the 4 smaller ones would be the limbs.

- All the robots are piloted by kids and together(with the help of the robots) , they became are the firefighters , policeman and the paramedics of the country

These are all the details that lingered in my mind. Sorry for the limited information . Please help me:(
