Abstract

The utility model provides a rear suspension component of an automobile engine, which is characterized by comprising a large rubber bush and a small rubber bush. The large rubber bush and the small rubber bush are connected through a welded bracket, wherein the large rubber bush comprises a metal outer tube, damping rubber is arranged in the metal outer tube, and a metal inner tube is arranged in the middle of the damping rubber; the small rubber bush comprises the metal inner tube, and the damping rubber is sleeved outside the metal inner tube; and the welded bracket comprises a large welded outer tube and a small welded outer tube, and the large welded outer tube and the small welded outer tube are respectively sleeved outside the metal outer tube and the damping rubber and are connected through a connecting bracket. The utility model has the advantages that: the design cost of the whole automobile is reduced; the comfortableness of the whole automobile is improved; the vibration acceleration values of the steering wheel and seats are less than 0.3G and less vibration of the power assembly is transferred to the compartment; and the dynamic and static stiffness values of the product in the radial direction, the axial direction and the torsion direction are all within design standards.

Description

Part suspends after the motor car engine

Technical field

The utility model relates to the part that suspends after a kind of motor car engine.

Background technique

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 travelling 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 manufacture cost is higher like this.

Summary of the invention

It is lower and have a part that suspends after the motor car engine of good NVH value that the purpose of this utility model provides a kind of manufacture cost.

In order to achieve the above object, the technical solution of the utility model has provided the part that suspends after a kind of motor car engine, it is characterized in that: comprise big rubber bushing and small rubber lining, link to each other by welding support between big rubber bushing and the small rubber lining, wherein:

Big rubber bushing 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 after the motor car engine that the utility model provides can realize former four-point arrange in before suspend part and after the suspend function of part, suspend after adopting promptly that the utility model provides behind the part, 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.

The utility model has the advantages that: 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 travelling comfort; 3, the every vibration acceleration value of steering wheel and seat has reduced the vibration of power 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

The part structural representation suspends after a kind of motor car engine that Fig. 1 provides for the utility model.

Embodiment

Specify the utility model below in conjunction with embodiment.

Embodiment

As shown in Figure 1, the part that suspends after a kind of motor car engine that provides for the utility model comprises big rubber bushing and small rubber lining, link to each other by welding support between big rubber bushing and the small rubber lining, wherein:

Big rubber bushing 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 vulcanization 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 vulcanization 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.

Working principle of the present utility model is: the part that suspends after the motor car 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 bushing 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 bushing supports see that the support 4 that is connected in the welding support links together.Assemble the part that suspends after the qualified motor car engine and be installed between vehicle body and the power assembly, the metal inner pipe 1 of small rubber lining is connected with the vehicle body of automobile, the metal inner pipe 8 of big rubber bushing is connected with automobile power assembly.At automobile starting or when jolting road conditions, the part that suspends after the motor car engine is by vibration isolation rubber 7 twisting actions in the big rubber bushing 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 automotive body.
