Abstract
The utility model relates to novel aluminum riveting fabricated suspension. The suspension comprises an upper housing, an elastic main spring and a lower base, wherein, the elastic main spring is positioned between the upper housing and the lower base; the upper housing and the lower base restrict the space position of the elastic main spring; the upper housing is fixedly connected to the lower base; and a flow channel is arranged in the lower base. The suspension can solve the product quality problem caused by an ordinary riveting manner, improve the product quality and the production efficiency, and simultaneously improve the NVH (noise, vibration and harshness) performance of parts.
Description
Technical field
The utility model relates to automobile power assembly and supports the vibration damping field that suspends, and particularly relates to a kind of novel aluminum riveted joint assembling type suspending apparatus.
Background technique
The main effect of automobile power assembly suspension system comprises: reduce vibration and the displacement of control power assembly that power assembly passes to vehicle body.The power assembly suspension system vibration is the part of vehicle complete vehicle vibration, it all has bigger influence to body vibrations and car room noise level, the quality of design on Mounting System will directly have influence on the vibration noise level of car load, be the key factor that influences riding comfort.Car load NVH Performance Influence Factor comprises a lot of aspects, and wherein the vibration from automobile power assembly suspension system is a key factor.The vibration source of automobile power assembly suspension system is reciprocal unbalance inertia force and the torque fluctuations that himself produces in the working procedure, automobile travels on various road surfaces in addition, because the vibrational excitation that road roughness causes also can exert an influence with power assembly suspension system.Therefore, the NVH characteristic of improving automobile power assembly suspension system self is an important channel, and good assembly relation influences the key factor of dynamic assembly suspension overall permanence especially.
At present, dynamic assembly suspension commonly used to the riveted joint mode cause easily riveting that head cracks, Root Stress is concentrated defectives such as serious, influence suspend life-span and even car load safety.In order to address the above problem, just need improve riveted joint design commonly used, reaching the purpose of improving the part riveting quality, and then improve the NVH characteristic of dynamic assembly suspension.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of novel aluminum riveted joint assembling type and suspends, and improves riveting quality, enhances productivity and product percent of pass.
The technological scheme that its technical problem that solves the utility model adopts is: provide a kind of novel aluminum riveted joint assembling type to suspend, comprise upper shell, elasticity master's spring and lower bottom base, described elasticity master's spring is between described upper shell and lower bottom base: described upper shell and lower bottom base limit the spatial position of described elasticity master's spring; Be fixedly connected with described upper shell on the described lower bottom base; Be provided with runner in the described lower bottom base.
The upper shell that described novel aluminum riveted joint assembling type suspends adopts the riveted joint mode to be connected with lower bottom base.
Chamfered is carried out in the hole of lower bottom base riveted joint place that described novel aluminum riveted joint assembling type suspends; Described upper shell riveted joint head is a blind hole.
Upper shell and lower bottom base that described novel aluminum riveted joint assembling type suspends are made by die casting aluminium.
Elasticity master's spring that described novel aluminum riveted joint assembling type suspends is made by natural rubber.
Beneficial effect
Owing to adopted above-mentioned technological scheme, the utility model compared with prior art, have following advantage and good effect: the utility model carries out chamfered in the hole of lower bottom base riveted joint place, upper shell riveted joint head is designed to blind hole, effectively improved riveting quality, improve manufacturing efficiency and product percent of pass, prolonged working life.

Fig. 2 is along the sectional view of A-A line among Fig. 1;
Fig. 3 is the partial enlarged drawing of B among Fig. 2.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Mode of execution of the present utility model relates to a kind of novel aluminum riveted joint assembling type and suspends, and as depicted in figs. 1 and 2, is made up of upper shell 1, elasticity master's spring 2 and lower bottom base 3.Described elasticity master's spring 2 is between described upper shell 1 and lower bottom base 3; The spatial position of described upper shell 1 and the described elasticity master's spring 2 of lower bottom base 3 restrictions; Be fixedly connected with described upper shell 1 on the described lower bottom base 3; Be provided with runner in the described lower bottom base 3, make liquid that elasticity master spring 2 contains in runner, flow, Free up Memory, thus play vibration-damping function.Wherein, upper shell 1 and lower bottom base 3 are made by die casting aluminium, and elasticity master's spring 2 is made by natural rubber.
Described upper shell adopts the riveted joint mode to be connected with lower bottom base, as shown in Figure 1, has 4 places riveting point.Assembling assembling of the present utility model is as follows: at first, elasticity master spring 2 is pressed in the lower bottom base 3.Then, upper shell 1 is placed on lower bottom base 3 tops.At last, 4 riveting points are pressed, be linked and packed with realization.As shown in Figure 3, chamfered is carried out in the hole of lower bottom base 3 riveted joints place, and wherein, a place chamfering is 1 * 45 °, and b place chamfering is 1 * 75 °, and riveting post and interporal lacuna are 0.1mm～0.15mm.Upper shell 1 riveted joint head need design blind hole, thereby guarantees riveted joint head wall thickness.This shows that the utility model has effectively improved riveting quality, improved manufacturing efficiency and product percent of pass, prolonged working life.
The utility model in use, lower bottom base 3 is connected with vehicle body, elasticity master's spring 2 is connected with motor by external support.When vehicle is in different operating mode, power assembly is because self gravitation reaches the various excitations from the road surface, form vibration source, at this moment the vibration of power assembly will pass to the utility model by the external support that suspends, the utility model reaches vibration-damping function by elasticity master spring self or by regulating liquid volume absorbing in the elasticity master spring confined space, vibration damping.
