Abstract
The utility model relates to an automobile power assembly supporting, limiting and vibration isolating device, in particular to an automobile power assembly rubber suspension cushion which comprises a main spring, an outer sleeve and an inner sleeve. The automobile power assembly rubber suspension cushion is characterized in that a protruding block is arranged on an axial end face of the suspension cushion, and the protruding block and the suspension cushion are in an integrated structure; and an n-shaped framework limit structure is arranged on the inner side of the lower end of the outer sleeve. According to the automobile power assembly rubber suspension cushion, the protruding block is arranged on the axial end face of the cushion, the n-shaped framework limit structure is arranged at the outer sleeve, and therefore effective limiting for the main spring when the main spring of the cushion moves downwards is achieved, deformation of the main spring is reduced, and durability is improved.
Description
Technical field
The utility model relates to a kind of automobile power assembly support, spacing, isolation mounting, particularly a kind of automobile power assembly rubber suspension cushion.
Background technology
Industry is NVH(Noise, Vibration, Harshness with the english abbreviation of noise, vibration and traveling comfort), be referred to as the NVH problem of vehicle, it is one of international automobile each large car load manufacturing enterprise of industry and parts enterprises problems of concern.The research of NVH characteristic not only is applicable to the development process of whole automobile new product, and is applicable to improve the research of existing vehicle travelling comfort.This is that some systems or an assembly for automobile carries out modeling analysis, find out the factor that travelling comfort is had the greatest impact, by improving driving source vibration state (range of decrease or shift frequency) or controlling the driving source vibration noise and improve travelling comfort to the indoor transmission of car.The vibration isolation research of automobile power assembly suspension system and the research of engine breathing noise are the important contents that improves the car load traveling comfort, and the development and perfection of power assembly hydraulic suspension system are solved this problem preferably.
On traditional car engine suspension structure design, often when guaranteeing NVH, can't guarantee the durable of product, produce contradiction.Common design process is to carry out first the design calculation in early stage, can select the scheme that a cover relatively adapts to NVH according to result of calculation afterwards, but often because the rigidity that suspends is lower, can cause durable not all right.On the basis of experiment and analysis, according to rigidity before, with the main spring lengthening of cushion, with the cross-sectional area overstriking of main spring, in theory, main spring lengthens simultaneously, stiffness degradation, and cross-sectional area strengthens (namely main spring chap), and rigidity increases.Like this, will produce a neutralization, can realize that the rigidity of two kinds of cushions is identical.We know, and are identical during the distortion of rubber generation under identical power effect if rigidity is the same, but a main spring is long, and a main spring is short, and the stretch ratio of rubber bodies distortion generation is just different so.Like this, the long rubber bodies of main spring is durable all right.According to the durability of product, very large a part of power all is to act on non-linear section simultaneously, and according to cushion before, cushion master spring can continue to move downward when touching limiting stopper, affects the durability degree of main spring.
The utility model content
The purpose of this utility model is to propose a kind of automobile power assembly rubber suspension cushion, has solved the low problem of main spring durability degree.
For reaching this purpose, the utility model by the following technical solutions:
A kind of automobile power assembly rubber suspension cushion comprises main spring, jacket and inner sleeve, it is characterized in that, is provided with a projection on the described suspending cushion axial end, and described projection and suspending cushion are the integral type structure.
Preferably, inside, described overcoat lower end has an a few font skeleton position limiting structure.
The utility model arranges a projection at the cushion axial end, and the overcoat place is provided with an a few font skeleton position limiting structure, guarantees that cushion master spring carries out main spring effectively spacing when moving downward, and reduces the distortion of main spring, thereby has promoted durability degree.
Description of drawings
Fig. 1 is original soft cushion structure schematic diagram;
Fig. 2 is soft cushion structure schematic diagram described in the utility model;
Fig. 3 is the jacket structure schematic diagram.
Among the figure:
1, inner sleeve; 2, main spring; 3, overcoat; 4, projection; 5, position limiting structure.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Figure 1 shows that original suspending cushion structural representation, among the figure as seen because main spring 2 is shorter, its cross-sectional plane is also less, and the overcoat 3 of cushion do not have position limiting structure, can not obtain effectively spacing when main spring 2 moves downward, easily cause the durability degree of main spring 2 low, cause fracture by fatigue.
As shown in Figure 2, the main spring 2 of suspending cushion is lengthened, simultaneously with the cross-sectional area overstriking of main spring 2, axial end at suspending cushion arranges a projection 4, described projection 4 is the integral type structure with suspending cushion, simultaneously arrange one to a few font skeleton position limiting structures 5 of inner sleeve 1 projection in overcoat 3 lower ends, guarantee that cushion master spring 2 carries out main spring 2 effectively spacing when moving downward, reduce the distortion of main spring.
The utility model arranges a projection at the cushion axial end, and overcoat 3 places are provided with an a few font skeleton position limiting structure 5, guarantees that cushion master spring 2 carries out main spring 2 effectively spacing when moving downward, and reduces the distortion of main spring 2, thereby has promoted durability degree.
Claims (2)
