Abstract

An automobile engine suspension structure comprises an upper framework, a bolt riveted on the upper framework, a lower framework and a connection rubber body. A horizontal-limit downwards-bent structure is arranged on one side of the upper framework, a rubber body is wrapped at the bent position, the center of the lower framework upwards protrudes, the rubber body at the bent position of the upper framework can be blocked by the protruded portion, and a reinforced rib is arranged at the bent position of the upper framework. The automobile engine suspension structure is simple in structure, changes an original engine rear suspension structure, changes an original limit method, can bend the rear suspension upper framework to limit horizontally, reduces the weight of an engine suspension, avoids adding left-right suspension cover to limit, shortens production flow, greatly reduces noise vibration and harshness (NVH) match difficulty of the whole automobile, saves raw materials, reduces production cost of the engine suspension and improves production efficiency.

Description

A kind of car engine suspension structure

Technical field

The utility model relates to a kind of car engine suspension structure.

Background technique

Car engine suspension is the damping device of installing for motor car engine, mainly is to put the back suspension device of engine of vehicle for motor is vertical, because therefore this suspend connecting engine and vehicle body more can play the effect of vibration and noise reducing.In traditional rear-suspending design, mainly be that the left and right outstanding increase cover cap that adopts comes the cross spacing effect, so both can increase the quality of engine mounting, also can increase cost simultaneously.

In sum, need to improve engine mounting, to alleviate its weight, reduce cost.

The model utility content

The purpose of this utility model is to propose a kind of car engine and suspends, and it is larger to have solved the engine mounting quality, the problem that cost of production is higher.

For reaching this purpose, the utility model by the following technical solutions:

A kind of car engine suspension structure, comprise upper skeleton and on riveted joint bolt, lower skeleton and connect colloid, described upper skeleton one side has the downward bending structure for cross spacing, and wrap rubber body at bending part, described lower skeleton core raises up, and blocks the rubber body of upper skeleton bending part with convex portion.

Preferably, the bending part of described upper skeleton is provided with stiffening rib.

Preferably, described upper skeleton bending part material selection SAPH440 steel plate, thickness is 5mm.

The utility model is simple in structure, changed the structure of original back suspension device of engine, change original limit method, carry out cross spacing by the bending that utilizes the rear overhang upper skeleton, not only alleviated the weight of engine mounting, and outstanding cover cap carries out spacing about not needing to increase again, shorten production procedure, greatly reduced the difficulty of car load NVH coupling, saved raw material, reduce the cost of production of engine mounting, improved manufacturing efficiency.

Fig. 2 is Figure 1A-A place half sectional view;

Fig. 3 is Figure 1B-B place partial sectional view;

Fig. 4 is the utility model overall structure three-dimensional view.

Among the figure:

Embodiment

Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.

As shown in Figures 1 to 4, comprise upper skeleton 2 and on riveted joint bolt 1, lower skeleton 4 and connect colloid, described upper skeleton 2 one sides have the downward bending structure for cross spacing, i.e. Fig. 1, Fig. 3, upper skeleton bending 21 shown in Figure 4, and wrap upper skeleton dogleg section colloid 22 at bending part;

As shown in Figure 2, the core of lower skeleton 4 has lower skeleton projection 41,, and block the rubber body at upper skeleton bending 21 places with convex portion;

For gaining in strength, be provided with stiffening rib at the bending part of described upper skeleton 2.

Upper skeleton bending material selection SAPH440 steel plate materials of the present utility model, thickness of slab adopts 5mm, through experimental examination, can satisfy the requirement of limited conditions.

It is spacing that the utility model adopts the upper skeleton bending structure to come laterally carrying out, and do not need left and right outstanding increase cover cap to be come laterally carrying out spacing again, alleviated the weight of engine mounting, saved the means of production, reduced production and processing process, improved manufacturing efficiency.

Claims
