Mount Apparatus for Transmission of Vehicle

The present invention relates to a mounting apparatus for a vehicle transmission. In more detail, a separate stopper mounted outside the main pipe is formed by separating the inner core located in the main pipe into two and forming a stopper unit for limiting the longitudinal displacement of the inner core between the two separated inner cores. The present invention relates to a mounting apparatus for a vehicle transmission in which a device can be miniaturized and can be miniaturized, and an inner core does not deviate from an insulator even during offset collision of a vehicle, thereby improving vibration damping support performance of a transmission and improving durability.

In general, an engine and a transmission assembly of a vehicle have a structure in which a lower end thereof is coupled to a subframe, and the subframe is coupled to a body frame forming an engine compartment so that the engine and transmission assembly are installed in the engine compartment.

Here, when the engine and the transmission assembly are installed in the engine room via the subframe, the engine and the transmission assembly are installed in a three point mount support structure or a four point mount support structure depending on the vehicle model. That is, the engine mount and the transmission mount are mounted on the engine and the transmission mount by one point, respectively, and the roll mount is mounted on the rear side of the engine and the transmission assembly by one point or two points and forms a three- or four-point mount support structure.

In this case, the transmission mount mounted on the transmission is disposed so that the vibration damping effect is exerted along the traveling direction of the vehicle for improving engine control and accelerating transmission sound of the vehicle in both the three-point and four-point mount support structures.

However, as shown in FIG. 1 (b), the inner core 30 is separated from the insulator 20 in the case of an offset collision of the vehicle. There was a problem of being easily broken. That is, when the impact force in the direction perpendicular to the vehicle traveling direction acts on the transmission mounting device during the offset collision of the vehicle, there is no stopper device for displacement of the insulator 20 and the inner core 30, and thus the transmission having such an arrangement structure Mounting device for the use has a problem that the inner core 30 is separated from the insulator 20 and easily broken.

Therefore, the present invention has been invented to solve this problem, by separating the inner core located in the main pipe into two and by mounting a stopper unit for limiting the longitudinal displacement of the inner core between the two separated inner cores Since it does not need a separate stopper device mounted on the outside of the main pipe, it can be miniaturized, and the inner core does not deviate from the insulator even in the case of offset collision of the vehicle, and thus maintains a steady state.
