Abstract
The invention relates to an installation structure for an engine assembly and a car body. The installation structure comprises a first supporting component which is arranged on the right of a supporting plate and in contact with the bottom surface of an oil pan arranged on the engine assembly. The installation structure is characterized in that a first installing hole is formed in the bottom surface of the oil pan and is matched and connected with an elastic component on the first supporting component, a rear supporting component and a front supporting component are arranged on the left of the supporting plate and are in contact fit with the bottom surface of a transmission arranged on the engine assembly, and a second positioning component arranged on the rear supporting component extends into and fit a second mounting hole formed in the bottom surface of the transmission. With the positioning structure, positioning precision of the engine assembly relative to the supporting plate can be improved, the assembling precision of the engine assembly and the car body can be increased, and then NVH (noise, vibration and harshness) performance of the whole car is guaranteed.
Description
Technical field
The present invention relates to a kind of location structure of automobile body part, be specifically related to the mounting structure of a kind of engine assembly and vehicle body.
Background technology
Engine assembly 1 is installed fixing with vehicle body by bracket 8 and pallet 9 at present.As shown in Fig. 2, Fig. 4 and Fig. 5, the middle part of right hand edge above of described pallet 9 is provided with the first locating dowel pin 9-1, and the left hand edge middle part on pallet 9 is provided with the second locating dowel pin 9-2; The bottom surface of described bracket 8 is provided with the first mounting hole 8-1 matching with the first locating dowel pin 9-1, the the second mounting hole 8-2 matching with the second locating dowel pin 9-2, the front end of described bracket 8 is provided with the first knock hole 8-4, rear end is provided with the second knock hole 8-3, described the first knock hole 8-4 is connected with the front suspending cushion 5 on engine assembly 1, and the second knock hole 8-3 is connected with the rear-suspending cushion 4 on engine assembly 1; By the backward rising of engine assembly 1 reversing, bracket 8 is fixed by bolt and vehicle body afterwards, and on engine assembly 1, set left suspending cushion 3 and the set right suspending cushion 2 of right part of left part is also bolted with vehicle body.
Although above-mentioned engine assembly location structure can be fixed on engine assembly on vehicle body, but, in front suspending cushion 5 and rear-suspending cushion 4, be equipped with Rubber Parts, after stressed, be out of shape uncontrollable, therefore, front suspending cushion 5 and rear-suspending cushion 4 are larger with the assembly clearance of bracket 8, cause the location consistency in relative bracket 8 short transverses of engine assembly 1 poor, again because between the bottom surface of engine assembly 1 and the upper surface of pallet 9 without location measure, thereby engine assembly 1 easy swing with vehicle body on horizontal surface swings, therefore the bottom surface contrast locating of engine assembly 1 is poor, thereby cause front suspending cushion 5 and rear-suspending cushion 4 and bracket 8 mounting hole decentraction, when running car, easily produce abnormal sound, have a strong impact on car load NVH(vehicle ride comfort) quality.
Therefore, current auto trade need find the method for solution.
Summary of the invention
The object of the present invention is to provide the mounting structure of a kind of engine assembly and vehicle body, this location structure can strengthen the positioning precision of the relative pallet of engine assembly, improves the assembly precision of engine assembly and car body, thereby guarantees the NVH quality of car load.
The mounting structure of a kind of engine assembly of the present invention and vehicle body, comprise the first load-carrying element that pallet right part is set, the cooperation that contacts with the bottom surface of set oil pan on engine assembly of this first load-carrying element, it is characterized in that: described oil pan is also provided with the first mounting hole on bottom surface, elastic component on this first mounting hole and the first load-carrying element is in mating connection, left part at pallet is provided with rear support member and front support member, before described, the cooperation that contacts with the bottom surface of set change-speed box on engine assembly of rear support member, described rear support member is provided with the second align member, this second align member stretches in the second set mounting hole of change-speed box bottom surface and with it and coordinates.
Described the first load-carrying element is provided with assembly opening, the spheroid that is provided with spring in this assembly opening and matches with assembly opening, and this spring and spheroid form elastic component.
Described the second align member is columniform locating dowel pin.
The present invention has the following advantages:
(1) two load-carrying element positioning heights that available engine assembly and pallet adopt are relatively thought about it the mode of displacement, obviously more stable by the structure of three load-carrying elements.
(2) set up after columniform locating dowel pin, can limit the displacement of the relative pallet of engine assembly left and right, fore-and-aft direction, strengthen the positioning precision of the relative pallet of engine assembly, improve the assembly precision of engine assembly and car body, thereby guarantee the NVH quality of car load.
(3) set elastic component can be alleviated the impact that the deformation in forward and backward suspending cushion short transverse causes the inconvenience of engine assembly fit on.
