Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model
Fig. 2 is the structural schematic diagram of vehicle frame in the utility model.
Specific embodiment
Combined with specific embodiments below and attached drawing is further described the utility model.
A kind of engine suspension structure as shown in the figure, including vehicle frame 1 and engine 2, wherein 1 front of the vehicle frame is set
Set standpipe 11.The main-beam pipe 12 oliquely downward extended is connected on the standpipe 11, in an embodiment of the present invention
Vehicle frame 1 uses tubular type vehicle frame, and wherein main-beam pipe 12 has four, upper and lower, left and right beam Guan Zucheng, and symmetrical structure, up and down
Beam pipe is oppositely arranged, and is provided with reinforced pipe between upper lower beam pipe.12 front of main-beam pipe is provided with suspension supporting frame
13；12 rear portion of main-beam pipe is bent downward, as Fig. 1 an embodiment of the present invention middle girder pipe 12 structure be it is upper,
Lower rear portion is bent downward simultaneously, and rear portion intersects and is welded as a whole.In conjunction with the suspension supporting frame 13, main-beam pipe 12 is to described
Engine 2 forms half package structure.Connecting tube 3 is hinged on the suspension supporting frame 13, and 3 other end of connecting tube is articulated with
The front of the engine 2；12 rear portion of main-beam pipe is equipped with chain stay hole 10, and above and below the chain stay hole 10
It is provided with mounting bracket 14,2 rear portion of engine is detachably connected with mounting bracket 14, and mounting bracket 14 at upper and lower two
Center of extension line intersection point be located at the crankshaft center on the engine and output axis center between.It is hung after being arranged so,
The support effect to engine 2 can be effectively improved, so that vehicle frame 1 has preferable rigidity and strong in the support to engine 2
Degree.
The suspension supporting frame 13 includes main suspension strut pipe 4, secondary suspension strut pipe 5, and main suspension strut pipe 4, pair are outstanding
It hangs support tube 5 and the main-beam pipe 12 forms triangular structure, wherein the main suspension strut pipe 4 and 2 middle cylinder of engine
The axis of body is in perpendicular at 10 ° -15 ° of acute angle.The main suspension strut pipe 4, secondary suspension strut pipe 5 junction set
Have a supporting sleeve 6,3 upper end of connecting tube has a connecting sleeve, and the connecting sleeve both ends are equipped with thread bush, and with institute
It states and is threadedly coupled between supporting sleeve 6.Stiffening plate is provided between the connecting sleeve and connecting tube 3.Vehicle frame 1 in this way is to starting
