Claims (4)

1. A subframe for a vehicle that will be attached to the body. It is a subframe for vehicles which is unique in that it consists of one side beam. Has been arranged to lie in the front and rear of the body with the front body installed. one on the front side in that rear line and one rear body mount on the rear side in Such front lines are fixed with fragile and The long side beams were arranged to extend in the front and rear of the hull facing in. Find such first side beam across the width of the said body with the front body mounting section Two of the aforementioned front-side and two rear-side body mounts have been defined with fragile parts and Arranged cross beams extend along this width together with the joints. such first crossbar and such second crossbar Such fragile portions of the first crossbeam are subjected to bent deformation with corrected sections. The compaction of such a fragile part of the first beam is the origin of the collision load which is received from the aforementioned front side to the aforementioned rear side during a frontal collision of the said vehicle, and such vulnerable parts of the said second side beam are deformed with the The crushing of the said vulnerable part of the second girder is the origin of the collision load. 2. A subframe for a motor vehicle specified in claim 1, which is characterized by Such first crossbeam shall have such a fragile part on such rear edge. At the slope, which slopes downward towards the bottom in the upper and lower line of the hull along the way to the back side The second beam will have such a fragile part on the rear edge. At the slope, which slopes downward towards the bottom in the upper and lower line of the hull along the way to the back side 3. A subframe for a motor vehicle mentioned in claim 1 or 2, which is characterized by The subframe for such vehicles consists of a first body mounting element in which the One center body mount is fixed between that first front body mount and the The first rear hull mount on the aforementioned front line has been made to the shore. Above in the upper and lower line of the said hull against the first side beam and the crossbar above is on the side. one of the aforementioned widths and the second body mount where the second center body mount is fixed between that second front body mount and the rear body mount that Two such front lines, behind the aforementioned, have been made projecting to the aforementioned upper side beams. Two such crossbars and such crossbars are on the other side of such width. The aforementioned vulnerable part of the first crossbar is fixed between the mounting sections. such first front hull and such first central hull mounting in such front and rear lines and there is one front hinge that will be bent towards that top side and one rear hinge that one which will be bent towards the bottom in such an upward direction with such compacted portions of The first crossbar was the starting point on that rear side than the first front crook. As mentioned when taking on the burden of such collisions The aforementioned vulnerable part of the second crossbar is fixed between the mounting sections. such second front hull and such second intermediate hull installation in such front and rear and there is a second front hinge that will be bent towards that top side and the rear hinge at two which shall be bent towards the lower side in such upper and lower lines with such compacted portions of The second crossbeam is the starting point on that rear side than the second front bend. As mentioned when taking on the burden of such collisions 4. A subframe for a motor vehicle specified in any one of the claims 1-3, which is characterized by The first crossbar has a vertical line which extends in such a sloping front and back. Tilt down to the lower side in such an upward direction along the way to that rear side. Such vulnerable parts of the first beam have compacted sections which are compacted in Such extends of such first beams from such collision loads such compaction sections shall It is assembled from the recess in which the upper wall portion of the first beam is collapsed towards the wall side. the bottom of such first beams to the concave in which such lower wall sections are sunk to the section side The upper wall is in a line at right angles to the line extending. Such second crossbar shall have a sloping line which extends in such anterior and posterior lines. Tilt down to the lower side in such an upward direction along the way to that rear side. Such vulnerable parts of the second girder will have compacted sections which will be compacted in The aforementioned extend of the aforementioned second girder from the aforementioned collision load in which the compaction section will It is formed from a recess in which the upper wall of the second beam is collapsed towards the wall side. the bottom of such second beam with the recess in which the lower wall section is reduced to the side of the wall on such a line perpendicular to the aforementioned line;
