Structure of motor-mount for electric vehicle

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.

Description

technical field [0001] The present invention relates to a structure of a motor bracket of an electric vehicle, and more particularly to a structure of a motor bracket of an electric vehicle that supports the lower part of a motor of an electric vehicle, wherein the outer peripheral surface of the stopper is in contact with the inner surface of the casing. The peripheral surfaces are in contact with each other, and a circular pressure ring engaged with the outer peripheral surface of the upper end of the stopper is also provided, and the stopper is pre-pressed by the pressure ring in the horizontal direction before being forcibly inserted into the housing. Background technique [0002] Vehicles equipped with gasoline engines and diesel engines using fossil fuels have many problems such as environmental pollution due to exhaust gas, global warming due to carbon dioxide, and respiratory diseases due to ozone. In addition, since the total amount of fossil fuels on the earth is l...

Problems solved by technology

[0013] However, in an electric vehicle where there is no reciprocating motion of the piston, such clearance is not conducive to shocks and jolts, and when the stopper moves back and forth causing vibration of the vehicle's firing crossbar, there is a large shock to the housing

[0014] Unlike ordinary gasoline vehicles with concentrated mass, electric vehicles may also be subject to shocks or jolts due to their structure in which the mass of the vehicle body is distributed over a large area and thus have a moment of inertia 5 to 7 times larger than ordinary gasoline vehicles Adverse effects of (jerk)
