AI Technical Summary

Benefits of technology

[0028]Since the inclined angle of the upper end surface of the stopper with respect to the horizontal axis of the stopper after being forcibly inserted into the housing is relatively smaller than the inclined angle of the upper end surface of the stopper with respect to the horizontal axis of the stopper before being forcibly inserted into the housing, the stopper is pressed by the pressing ring before being forcibly inserted into the housing so as to receive force in the vertical direction, and when the stopper is forcibly inserted into the housing, the stopper receives force in the horizontal direction. Accordingly, stiffness in the horizontal direction is remarkably more increased than stiffness in the vertical direction, so that shock vibration of the vehicle can be improved.

Problems solved by technology

Vehicles equipped with a gasoline engine and a diesel engine that use fossil fuel have many problems such as environment pollution caused by an exhaust gas, global warming caused by carbon dioxide, and a respiratory disease caused by ozone production.
Further, since there is a limited amount of fossil fuel on earth, the fossil fuel is in the danger of being exhausted.
Particularly, in the vehicle using the gasoline engine, a piston is operated in an order of suction, compression, explosion and exhaust through four stroke cycles to cause rotational torque of a crank shaft, and in this process, considerable vibration is generated.
However, in the hydro-mount structure, a high-frequency dynamic characteristic i

Abstract

A structure of a motor-mount for an electric vehicle that supports a lower part of a motor of an electric vehicle includes a core into which a bolt fastened to the motor is inserted in a center, a stopper that is coupled to surround an outer circumferential surface of the core, and is made of rubber, an insulator that is connected to a lower end of the stopper, is coupled to a lower part of the core, and has a concave lower surface, and a housing into which the core, the stopper and the insulator are forcibly inserted, where the housing has a cylindrical shape in which a bottom is opened, and an outer circumferential surface of the stopper comes in contact with an inner circumferential surface of the housing.
