Elastic connection tool for suspension and vehicle body mount structure for suspension
The elastic connection tool ( 1 A) comprises a first mounting member ( 22 ) that is provided with a first mounting portion ( 21 a ) and a rotating shaft ( 21 b ), wherein the rotating shaft ( 21 b ) attached to a tip of the first mounting portion ( 21 a ); a second mounting member that is provided with a second mounting portion ( 22 a ) and a bracket ( 22 b ), wherein the bracket ( 22 b ) comprises a recess (C 2 ) that accommodates the rotating shaft ( 21 b ) and an opening (A 2 ) that allows the first mounting portion ( 21 a ) to pass through therein in a swingable manner; a first elastic member ( 23 ) that connects the rotating shaft ( 21 b ) and the bracket ( 22 b ); and a second elastic member ( 25 ) that covers a tip-side portion of the rotating shaft ( 21 b ).
1 . An elastic connection tool for a suspension, comprising:
a first mounting member that is provided with a first mounting portion that is configured to be attached to either a vehicle body or wheel-side member and a suspension-side member, and a rotating shaft that extends in a direction intersecting the first mounting portion, wherein the rotating shaft is attached to a tip of the first mounting portion;
a second mounting member that is provided with a second mounting portion that is configured to be attached to the other of the vehicle body or wheel-side member and the suspension-side member, and a bracket that is continuous to the second mounting portion, wherein the bracket comprises a recess that accommodates the rotating shaft of the first mounting member and an opening that allows the first mounting portion of the first mounting member to pass through therein in a swingable manner;
a first elastic member that connects the rotating shaft of the first mounting member and the bracket of the second mounting member; and
a second elastic member that covers a tip-side portion of the rotating shaft on the side opposite to the first mounting portion,
wherein the first mounting member is composed of the first mounting portion and the rotating shaft as a single unit and
wherein the second elastic member is arranged in a compressed state between the rotating shaft and a mounting surface of the second mounting member and comprises a bore between the rotating shaft and the mounting surface of the second mounting member and
wherein the bore is opened directed to the mounting surface of the second mounting member.
2 . The elastic connection tool for a suspension as described in claim 1 , further comprising a pressing member that presses the second elastic member against the rotating shaft.
3 . A vehicle body mount structure for a suspension, comprising the elastic connection tool for a suspension as described in claim 1 , and the other of the vehicle body or wheel-side member and the suspension-side member that is attached to the second mounting portion of the elastic connection tool for a suspension.
4 . The vehicle body mount structure for a suspension as described in claim 3 , wherein
the second elastic member has a curved surface that extends in a circumferential direction around a center axis line of the rotating shaft, and
the other of the vehicle body or wheel-side member and the suspension-side member comprises a curved surface that matches the curved surface of the second elastic member.
5 . A vehicle body mount structure for a suspension, comprising the elastic connection tool for a suspension as described in claim 2 , and the other of the vehicle body or wheel-side member and the suspension-side member that is attached to the second mounting portion of the elastic connection tool for a suspension.
6 . The vehicle body mount structure for a suspension as described in claim 5 , wherein
the second elastic member has a curved surface that extends in a circumferential direction around a center axis line of the rotating shaft, and
the other of the vehicle body or wheel-side member and the suspension-side member comprises a curved surface that matches the curved surface of the second elastic member.
