Abstract

Abstract Support devices for automobile engine comprising attaching two buffers each comprising connecting the exterior surface of a metal shaft with the interior surface of a metal hollow cylinder arranged so as to surround the shaft in spaced relation by means of an elastic rubber member to provide higher and lower directions of the rigidities between the shaft and the metal cylinder at a plane perpendicular to the coextensive axes of the shaft and the metal cylinder in horizontal relation with respect to the coextensive direction of the shaft and the metal cylinder and connecting one end of either the shaft or the metal cylinder with the car body and another end thereof with the engine so that the coextensive line of the direction having higher rigidity intersects with a vertical plane through the center of gravity of the engine at a position below the intersection of the coextensive line directed to the direction having lower rigidity with the above-mentioned vertical plane to support symmetrically the engine on the car body in a laterally spaced relation, thereby eliminating the heavy noises generated by the operation of the automobile engine and preventing the separation of the engine from the car body.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 179 words
Devices for supporting an automobile engine comprising a buffer composed of a metal shaft, a metal hollow cylinder arranged so as to surround said shaft in spaced relation and an elastic rubber member provided under compressed condition between the interior surface of said metal cylinder and the exterior surface of said shaft, said elastic rubber member having three leg portions, two of which are in opposed relationship, for forming directions having higher and lower rigidities between said shaft and said metal cylinder at a plane perpendicular to the longitudinal axis of said buffer; and means for connecting said buffers to the engine and to a car body, said means for connecting each buffer being attached so that the coextensive line to the direction having said higher rigidity extends through said two opposed leg portions and intersects the vertical plane through the center of gravity of said engine at a position below the intersection of the coextensive direction having said lower rigidity with said vertical plane, and said buffers being attached symmetrically to the car body in laterally spaced relation.
Claim 2
Dependent Claim 179 words
Devices for supporting an automobile engine comprising a buffer composed of a metal shaft, a metal hollow cylinder arranged so as to surround said shaft in spaced relation and an elastic rubber member provided under compressed condition between the interior surface of said metal cylinder and the exterior surface of said shaft, said elastic rubber member having three leg portions, two of which are in opposed relationship, for forming directions having higher and lower rigidities between said shaft and said metal cylinder at a plane perpendicular to the longitudinal axis of said buffer; and means for connecting said buffers to the engine and to a car body, said means for connecting each buffer being attached so that the coextensive line to the direction having said higher rigidity extends through said two opposed leg portions and intersects the vertical plane through the center of gravity of said engine at a position below the intersection of the coextensive direction having said lower rigidity with said vertical plane, and said buffers being attached symmetrically to the car body in laterally spaced relation.
Claim 3
Dependent Claim 32 words
The devices according to claim 1 wherein each of said connecting means comprises brackets for connecting said shaft with the engine and brackets for connecting said metal cylinder with the car body.
Claim 4
Dependent Claim 33 words
The devices according to claim 1 wherein each of said connecting means comprises brackets for connecting said shaft with the car body and brackets for connecting directly said metal cylinder with the engine.
Claim 5
Dependent Claim 25 words
The devices according to claim 1 wherein said elastic rubber member has a plurality of perforated holes parallel to the longitudinal axis of said buffer.
Claim 6
Dependent Claim 32 words
The devices according to claim 1 wherein said elastic rubber member is attached adhesively between the interior surface of said metal cylinder and the exterior surface of said shaft by the vulcanization.
Claim 7
Dependent Claim 20 words
The devices according to claim 1 further comprising a sheath fitted forcedly on the exterior surface of said metal cylinder.
