Abstract
The invention provides a rear suspending member of an automobile engine. The rear suspending member is characterized by comprising a big rubber bushing and a small rubber bushing, wherein the big rubber bushing is connected with the small rubber bushing through a welding bracket; the big rubber bushing comprises an outer metal tube in which vibration isolating rubber is arranged; an inner metal tube is arranged on the middle part of the vibration isolating rubber; the small rubber bushing comprises an inner metal tube outside which vibration isolating rubber is sleeved; the welding bracket comprises a big outer welding tube and a small outer welding tube which are sleeved outside the outer metal tube and the vibration isolating rubber respectively; and the big outer welding tube is connected with the small outer welding tube through a connecting bracket. The rear suspending member has the advantages that: the design cost of the entire automobile is reduced; the comfort of the entire automobile is improved; each vibration acceleration value of a steering wheel and seats is less than 0.3G, and the transfer of the vibration of a power assembly into a carriage is reduced; and the dynamic stiffness value and the static stiffness value of the product in the radial direction, the axial direction and the torsion direction are within a design standard.
Description
Technical field
The present invention relates to the part that suspends behind a kind of automotive engine.
Background technology
Along with automobile quantity constantly increases with market competition more and more fiercely, the design cost budgetary request of car load is also more and more lower, but that people require the traveling comfort of car load is also more and more higher, thus the low-cost and high-performance car develop into a kind of inevitable trend.
In order to reach good NVH value (being Noise noise, Vibration vibration and Harshness sound vibration roughness), what the layout of engine mounting spare often adopted is that four-point is arranged, suspend before promptly adopting part, after part, left side part and the right side part that suspends that suspends that suspends, its manufacturing cost is higher like this.
Summary of the invention
It is lower and have a part that suspends behind the automotive engine of good NVH value to the purpose of this invention is to provide a kind of manufacturing cost.
In order to achieve the above object, technical scheme of the present invention has provided the part that suspends behind a kind of automotive engine, it is characterized in that: comprise big rubber bush and small rubber lining, link to each other by welding support between big rubber bush and the small rubber lining, wherein:
Big rubber bush comprises metal outer pipe, is provided with vibration isolation rubber in metal outer pipe, and metal inner pipe is located at the middle part of vibration isolation rubber;
The small rubber lining comprises metal inner pipe, is with vibration isolation rubber outside metal inner pipe;
Welding support comprises big welding outer tube and little welding outer tube, welds outer tube greatly and little welding outer tube is enclosed within respectively outside metal outer pipe and the vibration isolation rubber, and is continuous by being connected support between big welding outer tube and little welding outer tube.
The part that suspends behind the automotive engine provided by the invention can realize former four-point arrange in before suspend part and after the suspend function of part, after promptly adopting the part that suspends after provided by the invention, the layout of engine mounting spare can adopt bikini to arrange, thereby in the part that before saving, suspends, do not influence the NVH value again.
Advantage of the present invention is: the design cost that 1, has reduced car load; 2, simulate the compliance steer and the two-way function that turns in human limb joint, improved the car load traveling comfort; 3, the every vibration acceleration value of bearing circle and seat has reduced the vibration of dynamic assembly and has transmitted in the compartment less than 0.3G; 4, product radially, axially, the dynamic and static rigidity value on the torsional direction is all in design standard.
Description of drawings
Fig. 1 is the part structural representation that suspends behind a kind of automotive engine provided by the invention.
The specific embodiment
Specify the present invention below in conjunction with embodiment.
Embodiment
As shown in Figure 1,, comprise big rubber bush and small rubber lining, link to each other by welding support between big rubber bush and the small rubber lining for the part that suspends behind a kind of automotive engine provided by the invention, wherein:
Big rubber bush comprises metal outer pipe 6, is provided with vibration isolation rubber 7 in metal outer pipe 6, and metal inner pipe 8 is located at the middle part of vibration isolation rubber 7; Metal outer pipe 6, vibration isolation rubber 7 and metal inner pipe 8 make it to link together through the sulphurization of annotating the rubber machine.
The small rubber lining comprises metal inner pipe 1, is with vibration isolation rubber 2 outside metal inner pipe 1; Metal inner pipe 1 and vibration isolation rubber 2 make it to link together through the sulphurization of annotating the rubber machine.
Welding support comprises big welding outer tube 5 and little welding outer tube 3, welds outer tube 5 and little welding outer tube 3 greatly and is enclosed within respectively outside metal outer pipe 6 and the vibration isolation rubber 2, and is continuous by being connected support 4 between big welding outer tube 5 and little welding outer tube 3.Be welded to each other between big welding outer tube 5, little welding outer tube 3 and the connection support 4.
Principle of work of the present invention is: the part that suspends behind the automotive engine is through assembling big rubber bushing press-mounting in welding support, this process is to be installed together, the small rubber lining also to be fitted in the welding support afterwards again by the interference fit between the big welding outer tube 5 of the metal outer pipe 6 of big rubber bush and welding support, and this process is that the vibration isolation rubber 2 by the small rubber lining is installed together with little welding outer tube 3 interference fit, two rubber bush supports see that the support 4 that is connected in the welding support links together.Assemble the part that suspends behind the up-to-standard automotive engine and be installed between vehicle body and the dynamic assembly, the metal inner pipe 1 of small rubber lining is connected with automobile power assembly with the metal inner pipe 8 of the body contact of automobile, big rubber bush.At automobile starting or when jolting road conditions, the part that suspends behind the automotive engine is by vibration isolation rubber 7 twisting actions in the big rubber bush and vibration isolation rubber 2 twisting actions in the small rubber lining, alleviate the vibration that is produced by automobile power assembly well, this vibration can be delivered in the auto body.
