Abstract
The invention discloses a passive side bracket of an engine, which comprises an upper bracket and a lower bracket, wherein the upper bracket and the lower bracket are welded to form a hollow cavity; longitudinally-extending reinforcement plates are welded between the upper bracket and the lower bracket; the hollow cavity is divided into a plurality of hollow cavities by the reinforcement plates; the outer surface of the upper bracket is provided with a suspended mounting reinforcement plate; and the upper bracket, the lower bracket and the suspended mounting reinforcement plate are all metal plate stamping parts. In the passive side bracket of the engine, because a sealed cavity is formed by welding thin steel plates and the cavity body is divided into a plurality of small cavity bodies by the reinforcement plates, the internal structure of the part is enhanced, the static rigidness of the part is improved, and the inherent frequency of the part is improved, so that the integral vibration mode frequency of the whole bracket is improved, and the target value of engine bracket mode design is satisfied; and lightweight is realized, and cost is lowered.
Description
Technical field
The present invention relates to the automotive engine mounting structure, be specifically related to the passive side stand of a kind of driving engine.
Background technology
Along with auto trade develops towards energy saving direction, the design of auto parts and components requires also increasingly high to high strength, weight-saving.During the engine bed design, in order to satisfy car load NVH performance, parts progressively adopt the punching press soldering part to substitute mo(u)lded piece.The mode of punching press soldering part generally has two kinds at present: a kind of is between passive side stand of driving engine and body contact, to be provided with rubber pad; The passive side stand vibration modal frequency of driving engine value requires lower like this; But this structure is because number of spare parts is many, and relative cost is higher; Another kind is the direct and body contact of the passive side stand of driving engine, but must improve mount vibration model frequency value, the sympathetic body oscillation of avoiding the engine vibration excitation to cause.In order to improve the vibration modal frequency value, one adopts foundry goods or the thicker sheet metal component of thickness passive side stand, and weight is heavier, can not satisfy the requirement of car load light-weight design.
For example, in the patent documentation of State Intellectual Property Office of the People's Republic of China's issue, put down in writing " the passive side stand of a kind of driving engine ", publication number is CN101983874A.The passive side stand of driving engine adopts cavity structure shown in this patent; And in the support cavity, be welded with the lining pipe that is used for body contact; And increase the point of connection of support and vehicle body through lining pipe, thereby improve the rigidity of support, though directly and body contact can satisfy the requirement of part vibration modal frequency; But the structure more complicated is not easy to processing and installation.
Summary of the invention
The purpose of this invention is to provide the passive side stand of a kind of driving engine, it is simple in structure, intensity is high, in light weight, directly and body contact, can satisfy the requirement of vibration modal frequency value, and can cost-cutting.
The passive side stand of a kind of driving engine of the present invention; Comprise upper bracket and lower bracket; Upper bracket and lower bracket welding form cavity, are welded with the brace panel of longitudinal extension between said upper bracket and the lower bracket, through this brace panel cavity are divided into a plurality of areolas; Be provided with the installation brace panel that suspends in the outside of upper bracket, upper bracket, lower bracket and the installation brace panel that suspends are metal plate punching spare.
As preferably, said brace panel is divided into three areolas in left, center, right with the cavity that upper bracket and lower bracket surround.Make the passive side stand of driving engine have better rigidity, also satisfy the weight-saving requirement simultaneously.
Said upper bracket is provided with the reinforced rib of longitudinal extension, further increases the rigidity of upper bracket.
The said installation brace panel that suspends is located on the anterior dip plane of upper bracket.
The present invention compared with prior art has the following advantages: simple in structure, be convenient to processing and installation; Adopt the sheet steel welding to form an osed top cavity, through brace panel cavity is divided into a plurality of little cavitys, this structure is strengthened the inner structure of part, has improved the quiet rigidity of part; Improve the natural frequency of parts, thereby entire bracket body vibration model frequency is improved, satisfied engine bed mode design-calculated expected value; Realize lightweight, reduced cost.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view;
Fig. 3 is the B-B cutaway view;
Fig. 4 is a block diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Like Fig. 1, Fig. 2, Fig. 3 and the passive side stand of driving engine shown in Figure 4; Comprise upper bracket 1 and lower bracket 4; Lower bracket 4 forms an osed top cavity with upper bracket 1 welding; Between lower bracket 4 and upper bracket 1, be welded with brace panel 5, cavity from left to right be divided into a plurality of areolas successively, on upper bracket 1, be provided with the reinforced rib 2 of two longitudinal extensions through brace panel 5.On the dip plane of upper bracket 1 front portion, being connected with suspends installs brace panel 3, and upper bracket 1, lower bracket 4 and the installation brace panel 3 that suspends are metal plate punching spare.
As preferably, in the cavity that lower bracket 4 and upper bracket 1 surround, be welded with two brace panels 5, through two brace panels 5 cavity is divided into three areolas in left, center, right.
Brace panel 5 is welded on the lower bracket 4 through plug welding technology; Brace panel 5 is connected with upper bracket 1 through the mode that carbon-dioxide arc welding connects; Lower bracket 4 through carbon-dioxide arc welding and adopt the segmentation welding and upper bracket 1 to be welded to connect be an osed top cavity body structure, two brace panels 5 are divided into three the little cavitys in left, center, right with cavity.This structure is strengthened the inner structure of part, has improved the quiet rigidity of part.This structure has improved the natural frequency of parts, thereby has improved vibration modal frequency.After the cae analysis test, the vibration modal frequency value can satisfy the requirement of design objective value fully.
