Wherein, be respectively arranged with cushion block between the two ends of described ingot beam and the back suspension device of engine of its captive joint, described inboard bolt passes described cushion block.
(3) beneficial effect
The vehicle frame ingot beam installing mechanism that technique scheme provides, optimized the structure of ingot beam, reduced the structure of connection bracket and brace panel, back suspension device of engine and ingot beam are installed on the chassis side rail lower aerofoil in the hole altogether, reduce weight and reduce the parts kind, improve the parts integrated level, reduce cost, and can reserve the basifacial space of chassis side rail upper limb, be beneficial to the layout of tube bank circuit.
Description of drawings
Fig. 1 is the structural representation of vehicle frame ingot beam installing mechanism in the prior art;
Fig. 2 is the structural representation of the vehicle frame ingot beam installing mechanism of the utility model embodiment.
Wherein, 1: connection bracket; 2: longeron; 3: bolt of rear end plate; 4: brace panel; 5: ingot beam; 6: back suspension device of engine; 7: outside bolt; 8: inboard bolt; 9: cushion block.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Fig. 2 shows the structural representation of the ingot beam installing mechanism of present embodiment, with reference to diagram, this mechanism comprises the back suspension device of engine 6 that is installed in respectively on vehicle frame two side girders 2, the cross-sectional plane of described ingot beam 5 is set to U-shaped, and at the horizontal turnover board of two arranged outside of U-shaped opening, by horizontal turnover board fixed installation ingot beam.The two ends of ingot beam 5 are installed in respectively the below of vehicle frame two side girders 2 lower aerofoils, the two ends of described ingot beam 5 be bolted on respectively on chassis side rail 2 lower aerofoils and back suspension device of engine 6 on, the attachment point that is ingot beam 5 is not all to be arranged on the chassis side rail 2, but also has the partial fixing point to be positioned on the back suspension device of engine 6.
Particularly, described back suspension device of engine 6 is separately fixed on chassis side rail 2 sidewalls and chassis side rail 2 lower aerofoils by bolt, described back suspension device of engine 6 is fixed on chassis side rail 2 lower aerofoils by two outside bolts 7, and two described outside bolts 7 are near described chassis side rail 2 sidewall settings; The two ends of described ingot beam 5 also are fixed on described chassis side rail 2 lower aerofoils by two described outside bolts 7, namely two outside bolts 7 not only are fixed on an end of ingot beam 5 on chassis side rail 2 lower aerofoils, also back suspension device of engine 6 is fixed on chassis side rail 2 lower aerofoils, and ingot beam 5 is positioned at chassis side rail 2 lower aerofoils below, and with reference to Fig. 2, as can be known, two outside bolts 7 are actually an end that passes successively from the bottom to top ingot beam 5, chassis side rail 2 lower aerofoils and back suspension device of engine 6, the three is fixed together, one end of ingot beam 5 and back suspension device of engine 6 rely on one group of Kong Gongkong on chassis side rail 2 lower aerofoils to install, improved the integrated level of each parts, reduce cost, and can guarantee the stability that each parts is fixing fully.
Further, the firm intensity of fixing in order to strengthen ingot beam 5, the two ends of described ingot beam 5 also are fixed on the described back suspension device of engine 6 by two inboard bolts 8, two inboard bolts 8 and two described outside bolts 7 are arranged side by side, distance between two described inboard bolts 8 and described chassis side rail 2 sidewalls is greater than the distance between two described outside bolts 7 and described chassis side rail 2 sidewalls, namely reduce the number of openings on chassis side rail 2 lower aerofoils, guarantee the intensity of chassis side rail 2, with the support of back suspension device of engine 6 as ingot beam 5, further fixing ingot beam 5.Because the junction of back suspension device of engine 6 and ingot beam 5 does not have chassis side rail 2 lower aerofoils to support, so have the gap of certain altitude between back suspension device of engine 6 and the ingot beam 5, for the stability that guarantees to connect, between the back suspension device of engine 6 of the two ends of described ingot beam 5 and its captive joint, cushion block 9 is set respectively, fill the gap between back suspension device of engine 6 and the ingot beam 5, and make described inboard bolt 8 pass described cushion block 9, with the stable ingot beam 5 that firmly fixes.
As can be seen from the above embodiments, in the utility model ingot beam only by a blanked part assembly, simple in structure without accessory parts such as connection brackets, but expendable weight 5～6Kg; Ingot beam and back suspension device of engine are integrated, have reduced the parts kind; Because of without connection bracket and brace panel, alleviated weight, reduce one-tenth and produced cost; The chassis side rail upper half area is reserved sufficient space, and the tube bank circuit is easily arranged; Ingot beam and back suspension device of engine altogether hole are installed, and improve vehicle frame at the torque characteristic at back suspension device of engine place.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
