Limit object rotation on drag it

Hi!

My code allows click and drag on an object to rotate it applying a torque force (I use torque to obtain momentum/inertia).

Now I want to limit maximum and minimum degrees of the rotation, but I don't find the way.

Here is the code (js):

function Update () {

 if(mouseDown==true){        
             
     //Get how far the mouse has moved by using the Input.GetAxis().
     rotationX = Input.GetAxis("Mouse X") * sensitivityX;
     rotationY = Input.GetAxis("Mouse Y") * sensitivityY;
     
     //applying force
     rigidbody.AddTorque(Vector3.up * rotationX * -1 * 10);
     rigidbody.AddTorque(Vector3.right * rotationY * 10);
     
 }

}

function OnMouseDown(){

     mouseDown=true;        

}

function OnMouseUp(){

     mouseDown=false;        

}

I tried to Clamp X, this works, but no how I expect:

public var Min_X_Clamp:float = 30; 
 public var Max_X_Clamp:float = 150;
function LateUpdate() {
        transform.rotation.eulerAngles = new Vector3( Mathf.Clamp(transform.rotation.eulerAngles.x, Min_X_Clamp, Max_X_Clamp), transform.rotation.eulerAngles.y, transform.rotation.eulerAngles.z ); 
    }

Also I tried getting "transform.eulerAngles.x" directly, but I don't obtain a correct solution.

Somebody know how to limit rotation in this case?

A lot of thanks!
