Abstract
The present invention relates to the lining of a kind of car engine suspension cushion assembly, including outer tube, the inner sleeve being located at outer tube center and sulfuration vibration isolation rubber layer between inner sleeve and outer tube, it is characterized in that: described outer tube is composite construction, rigidity outer tube and flexible inner tube welding of fitting is constituted；Described rigidity outer tube is provided with two symmetrical rectangular openings, the height of this rectangular opening more than the height of described flexible inner tube, and the upper and lower side of described flexible inner tube respectively with the upper following seamed gap of described rectangular opening.The present invention can either realize good vibration isolation effect, improves car load NVH performance, ensure that again reliability.
Description
Technical field
The present invention relates to the component of car engine suspension cushion assembly, be specifically related to the lining of a kind of car engine suspension cushion assembly.
Background technology
Car engine suspension rubber bushing many employings single-stage vibration insulation structure at present, as shown in Figure 1, existing lining is made up of former outer tube 1, former inner tube 2, the sulfuration former partiting polarization rubber pad 3 between former outer tube and former inner sleeve, when the vibration of automobile power assembly or vehicle body is transferred on lining, lining inner sleeve and outer tube itself do not deform, but are deformed by the vibration isolation rubber between inner sleeve and outer tube and play flexible support and vibration isolation effect.The rubber bushing of the single-stage vibration insulation structure of this quasi-tradition is due to simple in construction, easily manufactured, with low cost, thus be widely used on automobile, it is the softest that the vibration isolation rubber of this tradition rubber bushing designs, then car load NVH performance is the best, but its fatigue reliability is the poorest；Otherwise, it is the hardest that vibration isolation rubber designs, then car load NVH performance is the poorest, but its fatigue reliability is the best, then in the design process of rubber bushing, needs be balanced between car load NVH performance and product reliability two indices and accept or reject.But, along with the individual demand of the development of auto industry, consumer is growing, car load NVH performance, product reliability are required all to become more and more higher by people, need badly and solve car load NVH performance and the problem that cannot simultaneously take into account of product reliability that the rubber bushing of traditional single stage vibration insulation structure exists.
Summary of the invention
It is an object of the invention to provide the lining of a kind of car engine suspension cushion assembly, it can either realize good vibration isolation effect, improves car load NVH performance, ensure that again reliability.
The lining of a kind of car engine suspension cushion assembly of the present invention, including outer tube, the inner sleeve being located at outer tube center and sulfuration vibration isolation rubber layer between inner sleeve and outer tube.Described outer tube is composite construction, rigidity outer tube and flexible inner tube welding of fitting is constituted；Described rigidity outer tube is provided with two symmetrical rectangular openings, the height of this rectangular opening more than the height of described flexible inner tube, and the upper and lower side of described flexible inner tube respectively with the upper following seamed gap of described rectangular opening.
Described vibration isolation rubber layer is divided into a variant part and two limiting sections vertically, has space between each limiting section and variant part；Said two limiting section staggers with two rectangular openings respectively.
The invention have the advantages that when the vehicle body of little amplitude or the vibration of power assembly are delivered on lining, the variant part of vibration isolation rubber layer plays one-level vibration isolation and vibrational energy of decaying by elastic deformation；And owing to rigidity outer tube is respectively equipped with rectangular opening at the position corresponding with the variant part two ends of described vibration isolation rubber layer, the position making described flexible inner tube corresponding with rectangular opening does not has the fixing restriction of rigidity outer tube, when vibration isolation rubber layer do not decay completely vibration be further transferred to flexible inner tube time, two grades of vibration isolation can be played and vibrational energy of decaying by metallic elastic deformation in flexible inner tube position at rectangular opening, improves overall NVH performance.Simultaneously as the rigidity of rigidity outer tube, intensity are higher so that the fatigue reliability of whole lining is higher.
When the vehicle body of big amplitude or the vibration of power assembly are delivered on lining, the deformation extent of the variant part of vibration isolation rubber layer is bigger, the limiting section of vibration isolation rubber layer can be extruded and produce elastic spacing effect, now, the deformation extent of the variant part of vibration isolation rubber layer can be reduced by the elastic deformation at the flexible inner tube position at rectangular opening, improve fatigue reliability.
In sum, present configuration is simple, and it had both had good vibration isolation effect, in turn ensure that product reliability, and it can take into account car load NVH performance and product reliability simultaneously.

Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Fig. 2 ~ Fig. 5, the lining of described a kind of car engine suspension cushion assembly, including outer tube, the inner sleeve 7 being located at outer tube center and sulfuration vibration isolation rubber layer 6 between inner sleeve and outer tube.Described outer tube is composite construction, rigidity outer tube 4 and flexible inner tube 5 welding of fitting is constituted；Described rigidity outer tube is provided with two symmetrical rectangular openings 41, the height of this rectangular opening more than the height of described flexible inner tube, and the upper and lower side of described flexible inner tube respectively with the upper following seamed gap 8 of described rectangular opening.
Described vibration isolation rubber layer 6 is divided into a variant part 61 and two limiting sections 62 vertically, has space 9 between each limiting section and variant part；Said two limiting section 62 staggers with two rectangular openings 41 respectively.
When the vehicle body of little amplitude or the vibration of power assembly are delivered on lining, the variant part 61 of vibration isolation rubber layer 6 plays one-level vibration isolation and vibrational energy of decaying by elastic deformation；And owing to described rigidity outer tube 4 is respectively equipped with rectangular opening 41 at the position corresponding with the variant part two ends of described vibration isolation rubber layer, the position making described flexible inner tube 5 corresponding with rectangular opening does not has the fixing restriction of rigidity outer tube, when vibration isolation rubber layer do not decay completely vibration be further transferred to flexible inner tube time, two grades of vibration isolation can be played and vibrational energy of decaying by metallic elastic deformation in flexible inner tube position at rectangular opening, improves overall NVH performance.Simultaneously as the rigidity of rigidity outer tube, intensity are higher so that the fatigue reliability of whole lining is higher.
When the vehicle body of big amplitude or the vibration of power assembly are delivered on lining, the deformation extent of the variant part 61 of vibration isolation rubber layer is bigger, the limiting section 62 of vibration isolation rubber layer 6 can be extruded and produce elastic spacing effect, now, the deformation extent of the variant part of vibration isolation rubber layer can be reduced by the elastic deformation at the flexible inner tube position at rectangular opening, improve fatigue reliability.
