How to use has one through in laravel?

I want to ask, there are three tables I’ve created, the following tables is bellow

brands

• brand_id
• brand_name

motorcycles

• motorcycle_id
• brand_id
• motorcycle_name

purchases

• purchase_id
• motorcycle_id
• purchase_price
• purchase_location

How to get data purchase_id, motorcycle_name and brand_name ?
I tried to use hasOneThrough() with model like this :

class Purchase extends Model
{
    protected $primaryKey = 'purchase_id';

    public function motorcycleBrand(){
        return $this->hasOneThrough(Brand::class,Motorcycle::class,'brand_id','brand_id');
    }
}

And this is code inside controller :

$data = Purchase::->with(['motorcycleBrand', 'motorcycle'])->get();
return response()->json($data);

But it’s not working, motorcycle data is showing but brand data is not showing (null).
Is it possible if I want to get data as I want ? If possible how to get it ?
Thank you..
