Engine mount for vehicle

Abstract

The invention discloses an engine mount for a vehicle. The engine mount may include an inner core having a bolt fastening portion, to which an engine connection bolt is fastened, and a stopper molding portion integrally formed on a lower end of the bolt fastening portion, and a forward-backward stopper integrally formed on a circumferential surface of the stopper molding portion, an upper insulator formed over a lower surface of the stopper molding portion, a saddle plate integrally formed on a lower surface of the upper insulator during a vulcanization molding, a lower insulator integrally formed on a lower surface of the saddle plate during the vulcanization molding, a fixing plate integrally formed on a lower surface of the lower insulator, a housing surrounding the upper and lower insulators and the forward-backward stopper, and a mounting bracket fastening a contact area between a lower end of the housing and an upper end of the fixing plate.

Description

technical field [0001] The invention relates to an engine mount for a vehicle. More particularly, the present invention relates to an engine mount for a vehicle having a novel structure in which insulators are provided on top and bottom of a saddle plate, thereby ensuring durability and three-way static / dynamic characteristics. Background technique [0002] As is well known in the art, as a means of reducing engine chatter due to vibration noise transmitted from the engine compartment through the vehicle body to the interior of the vehicle, as well as engine vibration, a Engine mount with anti-vibration function. In most cases, the engine mount is formed to have a structure in which an insulator made of a rubber material is provided and filled with a viscous liquid to provide a shock damping force. [0003] The following will refer to Figure 4 Let's describe the conventional engine mount structure in detail. [0004] A conventional engine mount includes: an inner core 10...

AI Technical Summary

Problems solved by technology

[0009] In the case where the inner core 100 is greatly deformed, if the deformation of the insulator 110 formed of rubber is small, its durability can be maintained, but the insulator 110 is prone to excessive compression deformation, thereby reducing the durability

[0010] Also, the groove 116 formed on the lower surface of the insulator 110 reduces the forward-backward stiffness in case of displacement of the insulator 110

However, in the case of a large displacement of the insulator 110, the groove 116 is easily deformed, thereby reducing the durability of the insulator 110.

[0011] Also, during acceleration and deceleration on a rough road, the forward-rearward damping force of the engine mount is too large, so the upper end of the insulator 110 (that is, integrally formed with the stopper molding portion 104 of the inner core 100 and Forming the forward-rearward stopper 114 of minute thickness) is easy to be torn, and this is very serious problem
