I want enable|disable child radio group with his parent checkbox. Pls help me.

Providing your HTML wouldn't hurt...

Let's say it looks like this:

<div>
  <input type="checkbox" value="1" name="c1" />
  <input type="radio" name="r1" value="1" />
  <input type="radio" name="r2" value="1" />
</div>
<div>
  <input type="checkbox" value="1" name="c1" />
  <input type="radio" name="r1" value="1" />
  <input type="radio" name="r2" value="1" />
</div>

With jQuery you can do something like this:

$(function(){
  $("input:checkbox").click(function(){
    if ( $(this).is(":checked") ){
      $(this).nextAll("input:radio").attr("disabled",true);
    }
    else{
      $(this).nextAll("input:radio").attr("disabled",null);
    }
  });
});

EDIT

I'd suggest first you divide your table into TBODYs:

    <table>
        <tbody>
            <tr>
                <td colspan=3><input type=checkbox class="filter-checkbox" name=serv1 value=1>ВъездАвто</td>
            </tr> 
            <tr>
                <td><input type=radio id=servch1 name=servch1 value=6000><a>г/п 10Т</a></td>
                <td><a>Сумма:&nbsp;6000</a></td>
                <td><a>НДС:&nbsp;1200</a></td>
            </tr> 
            <tr>
                <td><input type=radio id=servch1 name=servch1 value=4200><a>г/п 7Т</a></td>
                <td><a>Сумма:&nbsp;4200</a></td>
                <td><a>НДС:&nbsp;840</a></td>
            </tr> 
            <tr>
                <td><input type=radio id=servch1 name=servch1 value=3000><a>г/п 5Т</a></td>
                <td><a>Сумма:&nbsp;3000</a></td>
                <td><a>НДС:&nbsp;600</a></td>
            </tr> 
            <tr>
                <td><input type=radio id=servch1 name=servch1 value=1800><a>г/п 3Т</a></td>
                <td><a>Сумма:&nbsp;1800</a></td>
                <td><a>НДС:&nbsp;360</a></td>
            </tr> 
        </tbody>
        <tbody>
            <tr>
                <td colspan=3><input type=checkbox class="filter-checkbox" name=serv2 value=2>ХранСутки40фут</td>
            </tr> 
            <tr>
                <td><input type=radio id=servch2 name=servch2 value=5300><a>гружен.</a></td>
                <td><a>Сумма:&nbsp;5300</a></td>
                <td><a>НДС:&nbsp;1060</a></td>
            </tr> 
            <tr>
                <td><input type=radio id=servch2 name=servch2 value=3000><a>порожн.</a></td>
                <td><a>Сумма:&nbsp;3000</a></td>
                <td><a>НДС:&nbsp;600</a></td>
            </tr>
            .... 

Then you can do this:

$(function(){
  $("table input:checkbox").click(function(){
    if ( $(this).is(":checked") ){
      $(this).parents("tbody").find("input:radio").attr("disabled",true);
    }
    else{
      $(this).parents("tbody").find("input:radio").attr("disabled",null);
    }
});

});
