A kind of mounting support structure of engine rod-pulling type suspension
The invention belongs to body of a motor car field, a kind of mounting support structure of engine rod-pulling type suspension is specifically referred to.
In three-point suspension, rear-suspending is largely rod-pulling type suspension, and the suspension one end is connected with power assembly, and the other end is connected with vehicle body or subframe, and there is rubber bushing at pull bar suspension two ends, the twisting vibration of main decay power assembly in vehicle.
Engine mounting can not only decay the vibration of power assembly, prevent that vibration from transmitting to vehicle body, isolate because of the vibration effect engine work that Uneven road is produced, can also support power assembly, limit the moving region of power assembly, protect power assembly.
The car arranged for FF formulas, it is use three-point suspension structure more, i.e.,：The weight of left and right mount supports power assembly；Rear overhang is set to rod-pulling type, undertakes the output torque of power assembly.
However, in the case of two kinds below, it is difficult to will appear from suspension arrangement, 1, for part B grade car or C grade cars, because enging cabin interior section system causes suspension arrangement difficulty using bulky structure；2nd, for most A grades of cars and its car of following rank, relative to B, C grades car spaces of enging cabin are smaller, to arrange that the various part apparatus of quantity identical with bus just seem difficult wherein.At this moment, it is possible to reference to rod-pulling type described herein suspension, the arrangement space of increase rod-pulling type suspension, so as to solve the problems, such as difficult arrangement.
Now in the car of most of three-point suspension, the suspension of post-tensioning rod-type is arranged according to the form of figure below mostly, as depicted in figs. 1 and 2, mounting bracket is suspended the mounting hole of one end bushing by two structure composition support beams separated and rod-pulling type, hole 1, hole 2 and hole 3 are first connected with gearbox on support, a project-welding nut is welded on bracket holes 4, then the big end of suspending cushion is connected with fore sub frame, between two panels stamping parts residing for small end inserting hole 4, then it is connected with hole 4 and while brings into project-welding nut, last urgent torque.The shortcoming of the structure is that mounting structure easily loosens, and the space taken is larger.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, improved technology scheme is proposed, by the technical program, the nervous problem of enging cabin internal volume can be improved.
The present invention is achieved by the following technical solutions：
A kind of mounting support structure of engine rod-pulling type suspension, includes support beam structure and U-shaped supporting structure；The support beam structure is fixedly connected with U-shaped supporting structure；
The support beam structure includes inner support beam and outer support beam；The outer support beam side is extended outward into
Projective structure；The position that the projective structure connects with support beam is bent to inner support beam；The first mounting hole and the second mounting hole are provided with inner support beam and outer support beam, the 3rd mounting hole is provided with projective structure；
The bottom of the U-shaped support is fixedly connected with support beam structure；Two of U-shaped support are provided with the 4th relative mounting hole on picking up the ears.
One of the U-shaped support is picked up the ears, projective structure and the plane described in inner support beam are engaged with the shape of gear-box side wall.
First mounting hole, the second mounting hole, the 3rd mounting hole and the 4th mounting hole are fixedly connected by bolt with gearbox.
Two of the U-shaped support pick up the ears to be respectively arranged at the bushing both sides of rod-pulling type suspension small end, and are fixedly connected by bolt with gearbox.
The beneficial effects of the invention are as follows：
Technical scheme solves part vehicle because arrangement space not enough causes the problem of suspension of post-tensioning rod-type can not be arranged；Compared to more current existing scheme, the invention saves a project-welding nut.

Describe technical scheme in detail below by way of specific embodiment, following embodiment is exemplary only, is only capable of for explaining and illustrating technical scheme, and is not to be construed as the limitation to technical solution of the present invention.
As shown in Figures 3 to 5, a kind of mounting support structure of engine rod-pulling type suspension, includes support beam structure 5 and U-shaped supporting structure 10；The support beam structure 5 is fixedly connected with U-shaped supporting structure 10.
The support beam structure 5 includes inner support beam 12 and outer support beam 11, and inner support beam 12 and outer support beam 11 pass through stamping connection；The side of outer support beam 11 extends outward into projective structure 13；The position that the projective structure 13 connects with support beam is bent to inner support beam；The first mounting hole 6 and the second mounting hole 7 are provided with inner support beam and outer support beam, the 3rd mounting hole 9 is provided with projective structure 13；First mounting hole is suspended close to rod-pulling type, and the second mounting hole is suspended away from rod-pulling type.
The bottom of the U-shaped supporting structure 10 is fixedly connected by welding with support beam structure 5；Two of U-shaped supporting structure 10 are provided with the 4th relative mounting hole 8 on picking up the ears.
One of the U-shaped support is picked up the ears, projective structure and the face described in inner support beam are engaged with the shape of gear-box side wall；In this embodiment, one of U-shaped support picks up the ears, projective structure and the face described in inner support beam are plane.
First mounting hole 6, the second mounting hole 7, the 3rd mounting hole 9 and the 4th mounting hole 8 are fixedly connected by bolt with gearbox.Two of the U-shaped support 10 pick up the ears to be respectively arranged at the both sides of bushing 15 of rod-pulling type suspension small end, and are fixedly connected by bolt with gearbox.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, it is appreciated that without departing from the principles and spirit of the present invention these embodiments can be carried out a variety of change, modification, replacement and modification, the scope of the present invention is by appended claims and its equivalent limits.
