Hi Fluence,
I accept that you speak English,
better than i speak Portugese.
But it is not good enough to describe with brief sentences.
To understand what you say, please say it more ways.
Use more descriptions of your problem, to be understood.
Ok.

(still trying to display pictures, i feel such a twit)
Your description of the motor is inadequate,
so based on the circuit you have given,
i have presumed it is like the one shown below.
Live.jpg (shown below, cos i cant figure out how to show it here)
If it is arranged like this,
then it can not be reversed while in motion.
While its going, it can not be driven the other way.
It cant be driven into reverse when its running.
------------
This type of motor has to be stopped before going the other way.
Before reversing direction, this type has to be stopped.
To go the other way, this type of motor has to stop first.
------------
If you want to direct this motor from two locations,
you will need the relays to have a little sequence of actions.
To control the motor rotation from two different places,
the relays will have to do a small series of events.
------------
First,
to cut motor power,
to switch motor off,
to remove motor supply.
------------
Maybe also short to assist stopping.
Might connect loading to motor to help stop motion.
Shorting or loading may be desired to help stop motor.
------------
Then,
short period allowed to ensure stopped.
No action for small time for motion to cease.
Allow time to stop.
------------
Then,
apply drive in new direction.
connect supply for other way.
replace motor power in reverse.

In circuits i have made to do this in the past,
i have used capacitors to hold relays for short intervals,
to allow the motor to stop.
In the past i have used capactors with relays to do this job.
------------
A modern way would probably use press buttons and a PIC to set
the intervals and operate the relays to suit the buttons.
You might choose to use a PIC with press buttons
to drive relays for timing and controlling the motor.
------------
To do this with simple relays and switches might not be possible,
and you would need to have DC to use capacitors for timing.
I think you would have to use press buttons for control switching.
If you want to use simple relays and press buttons,
you will have to include a DC supply for the timing capacitors.
Such a circuit would be quite involved.
------------
See what others say, as there are many ways to get to Rome.
Someone may know a way that suits you.
