Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
157 words
An auxiliary mechanism mounting structure for mounting an auxiliary mechanism on an engine comprising an auxiliary mechanism mounting portion whose bearing rigidity is high in a direction substantially parallel to an axis of a crankshaft of the engine and is low in a substantially transverse direction to that of the axis of the crankshaft of the engine so that the auxiliary mechanism is easy to vibrate in a direction which is substantially transverse to the direction of the axis of the crankshaft of the engine; and a damping means for damping vibration of said auxiliary mechanism; wherein said auxiliary mechanism is driven by a driving belt which is passed around a crank pulley connected to the crankshaft of the engine and a pulley connected to said auxiliary mechanism, and said damping means comprises at least another driving belt which is passed around a pulley connected to said auxiliary mechanism and a pulley connected to another auxiliary mechanism.
Claim 2
Dependent Claim
157 words
An auxiliary mechanism mounting structure for mounting an auxiliary mechanism on an engine comprising an auxiliary mechanism mounting portion whose bearing rigidity is high in a direction substantially parallel to an axis of a crankshaft of the engine and is low in a substantially transverse direction to that of the axis of the crankshaft of the engine so that the auxiliary mechanism is easy to vibrate in a direction which is substantially transverse to the direction of the axis of the crankshaft of the engine; and a damping means for damping vibration of said auxiliary mechanism; wherein said auxiliary mechanism is driven by a driving belt which is passed around a crank pulley connected to the crankshaft of the engine and a pulley connected to said auxiliary mechanism, and said damping means comprises at least another driving belt which is passed around a pulley connected to said auxiliary mechanism and a pulley connected to another auxiliary mechanism.
Claim 3
Dependent Claim
21 words
An auxiliary mechanism mounting structure as defined in claim 1, wherein said another auxiliary mechanism is disposed above said auxiliary mechanism.
Claim 4
Dependent Claim
21 words
An auxiliary mechanism mounting structure as defined in claim 1, wherein said another auxiliary mechanism is disposed below said auxiliary mechanism.
Claim 5
Dependent Claim
31 words
An auxiliary mechanism mounting structure as defined in claim 1, wherein said another auxiliary mechanism includes at least two auxiliary mechanisms which are respectively disposed above and below said auxiliary mechanism.
Claim 6
Dependent Claim
22 words
An auxiliary mechanism mounting structure as defined in claim 1, in which said auxiliary mechanism is a compressor for an air conditioner.
Claim 7
Dependent Claim
145 words
An auxiliary mechanism mounting structure for mounting an auxiliary mechanism on an engine comprising an auxiliary mechanism mounting portion whose bearing rigidity is high in a direction substantially parallel to an axis of a crankshaft of the engine and is low in a substantially transverse direction to that of the axis of the crankshaft of the engine so that the auxiliary mechanism is easy to vibrate in a direction substantially transverse to the direction of the axis of the crankshaft of the engine; damping means for damping vibration of said auxiliary mechanism; and a mounting bracket which is fixed to the engine and to which said auxiliary mechanism is fixed, wherein said damping means comprises a vibration damper which includes a pair of metal plates and an elastic plate positioned between the metal plates and is connected between the mounting bracket and said auxiliary mechanism.
Claim 8
Dependent Claim
145 words
An auxiliary mechanism mounting structure for mounting an auxiliary mechanism on an engine comprising an auxiliary mechanism mounting portion whose bearing rigidity is high in a direction substantially parallel to an axis of a crankshaft of the engine and is low in a substantially transverse direction to that of the axis of the crankshaft of the engine so that the auxiliary mechanism is easy to vibrate in a direction substantially transverse to the direction of the axis of the crankshaft of the engine; damping means for damping vibration of said auxiliary mechanism; and a mounting bracket which is fixed to the engine and to which said auxiliary mechanism is fixed, wherein said damping means comprises a vibration damper which includes a pair of metal plates and an elastic plate positioned between the metal plates and is connected between the mounting bracket and said auxiliary mechanism.
Claim 9
Dependent Claim
42 words
An auxiliary mechanism mounting structure as defined in claim 6 in which said auxiliary mechanism is fixed to the auxiliary mechanism mounting portion in a plane which is near the vertical line passing through the center of gravity of the auxiliary mechanism.
Claim 10
Dependent Claim
71 words
An auxiliary mechanism mounting structure as defined in claim 6 in which said auxiliary mechanism mounting portion comprises a mounting bracket which is fixed to the engine and to which said auxiliary mechanism is fixed, and said damping means comprises a pair of elastic members which are interposed between an upper portion of the mounting bracket and the engine and between a lower portion of the mounting bracket and the engine.
Claim 11
Dependent Claim
22 words
An auxiliary mechanism mounting structure as defined in claim 6 in which said auxiliary mechanism is a compressor for an air conditioner.
