Next,, with reference to Fig. 2 and Fig. 3, the structure of the underframe 5 of the car frame 4 of the gross load to supporting cage 2 describes.
Underframe 5 comprises: a pair of front and back are to beam 10, and they leave preset distance at the Width of cage 2, arranges parallel to each other, and extends along depth direction; And pair of beams 13, they link up a pair of front and back between the vibrationproof portion material installation portion of the end side of beam 10, and underframe 5 is configured to rectangular frame shape.
Front and back are made up of U-steel to beam 10, described U-steel is by steel plate bending moulding being made into portion's material that cross section is コ word shape, before and after there is web portion 11 and pair of flanges portion 12 to beam 10, described pair of flanges portion 12 is bent into right angle from the two ends of the Width of web portion 11 towards same side and forms.
Crossbeam 13 has: web portion 14; Pair of flanges portion 15, its two ends from the Width of web portion 14 are bent into right angle and form towards same side; As a pair of the 1st folding portion 16 of rib, its length direction two ends from web portion 14 are bent into right angle and form towards same side, and are configured to clip along its length pair of flanges portion 15; And as a pair of the 2nd folding portion 17 of rib, its end from a pair of the 1st folding portion 16 is bent into right angle and forms towards same side, and it is opposed with web portion 14 to be configured to leave preset distance with respect to the end of pair of flanges portion 15.And crossbeam 13 carries out bending process to the end side of U-steel and forms, described U-steel is by steel plate bending moulding being made into portion's material that cross section is コ word shape.
At this, vibration-proof rubber 3, front and back are described to the size relationship of beam 10 and crossbeam 13.
Vibration-proof rubber 3 is made into cuboid, and this cuboid has with front and back to roughly consistent width, length W1 and fixed thickness of the width D 1 of the flange part 12 of beam 10.Front and back have the length roughly equal with the depth direction length of cage 2 to beam 10, and crossbeam 13 has the length slightly shorter than the Width length of cage 2.In addition, the distance H 1 between the distance between the outside face of pair of flanges portion 15 (height of crossbeam 13), i.e. the 1st folding portion 16 and the height H 2 of the 2nd folding portion 17 and the inside face of pair of flanges portion 12 is roughly consistent.Length W2 between the outside face of the outside face of web portion 14 and the 2nd folding portion 17, roughly consistent with the length W1 of vibration-proof rubber 3.The width D 2 of the 2nd folding portion 17 is slightly shorter than the width D of flange part 12 1.
In order to assemble underframe 5, first, by a pair of front and back to beam 10 so that the mode that the open side in コ word shape cross section is faced is mutually configured to leave the distance roughly equal with the width of cage 2 parallel to each other.Next, before and after the both ends of pair of beams 13 are inserted into the end side of the length direction of beam 10, and by this pair of beams 13 so that the mode that the open side in コ word shape cross section is faced is mutually configured to parallel to each other.Now, the terminal surface of the terminal surface of the 2nd folding portion 17 and pair of flanges portion 12 is roughly in same plane.Then, by welding or bolt etc., flange part 12 and flange part 15 are joined together, thereby are assembled into underframe 5.And vibration-proof rubber 3 is to be installed in the outside face of the flange part 12 of upside to beam 10 and the mode of the cross part top of crossbeam 13 before and after being positioned at.
In the underframe 5 forming like this, the load of cage 2 is applied to front and back to beam 10 via vibration-proof rubber 3, thereby produces the effect that the flange part 12 of upside is out of shape in the following manner: the end side of the flange part 12 of upside sinks downwards taking the connecting part between flange part 12 and the web portion 11 of upside as fulcrum.
At this, in the situation that there is no the 1st and the 2nd folding portion 16,17, the distortion of the flange part 12 of upside is born by the web portion 14 and the pair of flanges portion 15 that insert between pair of flanges portion 12.And, due to web portion 14 with and the orthogonal mode of the inside face of flange part 12 be inserted between the end of length direction of pair of flanges portion 12, therefore, the displacement that the end side of the flange part 12 of upside sinks is downwards born by web portion 14, thereby the distortion at the A place of the flange part of upside 12 in Fig. 2 is prevented from., because flange part 15 is single armed supporting (sheet is held Chi support), therefore, the distortion at the B place of the flange part 12 that cannot avoid upside in Fig. 2.
In this underframe 5, due to the 1st folding portion 16 with web portion 11 separation and and the parallel mode of web portion 11 be inserted between pair of flanges portion 12, therefore, make the fulcrum that the flange part 12 of upside is out of shape be transferred to the flange part 12 of upside and the cross part of the 1st folding portion 16 from the flange part 12 of upside with the connecting part of web portion 11.Thus, from fulcrum that the flange part 12 of upside is out of shape to the distance till the end of flange part 12 is shortened, thereby the opposing of the flange part of upside 12 makes the bending rigidity that the end side of the flange part 12 of upside sinks become large downwards.In addition, because the 2nd folding portion 17 is along the edge part of the inner side of the length direction region that vibration-proof rubber 3 is set between pair of flanges portion 12, forward backward beam 10, to insert with the orthogonal mode of the inside face of flange part 12, therefore, the displacement that the end side of the flange part 12 of upside sinks is downwards born by the 2nd folding portion 17, thereby the distortion at the B place of the flange part of upside 12 in Fig. 2 is prevented from.
Like this, according to this embodiment 1, the distortion at the setting area place of vibration-proof rubber 3 to the flange part 12 of the upside of beam 10 before and after can suppressing, and without increasing as front and back the thickness of slab to the steel plate of the material of beam 10 and crossbeam 13.Therefore, can suppress as front and back, to the thickening of the steel plate of the material of beam 10 and crossbeam 13, before and after making, to become easily to the bending process of beam 10 and crossbeam 13, thereby can realize cost degradation.And, can realize the lightweight of front and back to beam 10 and crossbeam 13, i.e. the lightweight of car frame 4.
The 2nd folding portion 17 of being out of shape for the flange part 12 that suppresses upside is integrally formed in crossbeam 13, and can make simply, therefore, can easily tackle the design modification of vibration-proof rubber 3.
In addition the steel plate that, crossbeam 13 can be cut into by liquidating following shape carries out bending process to be made: described shape is that web portion 14, pair of flanges portion 15, the 1st folding portion 16 and the 2nd folding portion 17 are launched to the shape forming in the plane.Therefore, can manufacture at an easy rate crossbeam 13, and without special device.In addition, owing to carrying out one-body molded to the work as rib material the 1st and the 2nd folding portion 16,17 in the manufacturing process of crossbeam 13, therefore without making separately rib material, also without the assembly process of the increase of welding rib material etc., thereby improved the assembling of underframe 5.
