Abstract
An engine bracket including: an attachment portion provided in a fixing location adapted to be fixed to at least one of the vehicle body and power unit; a bolt hole being formed in the attachment portion so that the attachment portion is fixed to the vehicle body or power unit by a fixing bolt inserted into the bolt hole; and at lease one breaking groove formed at an area located spaced away from the bolt hole so as to extend away from the bolt hole and toward an outer peripheral edge of the attachment portion on at least one of opposite surfaces of the attachment portion in a direction in which the fixing bolt is inserted.
Claims11
An engine bracket that is installed between a vehicle body and a power unit for the vibration damping support of the power unit relative to the vehicle body, the engine bracket comprises:
- an attachment portion provided in a fixing location adapted to be fixed to at least one of the vehicle body and power unit;
- a bolt hole being formed in the attachment portion so that the attachment portion is fixed to the vehicle body or power unit by a fixing bolt inserted into the bolt hole;
- and
- at lease one breaking groove formed at an area located spaced away from the bolt hole so as to extend away from the bolt hole and toward an outer peripheral edge of the attachment portion on at least one of opposite surfaces of the attachment portion in a direction in which the fixing bolt is inserted.
An engine bracket for connecting a power unit to a body of an automotive vehicle via an engine mount, comprising:
- a main panel portion extending in a longitudinal direction of the vehicle, and having an attachment portion formed at a rear end of the main panel portion in the longitudinal direction of the vehicle, the attachment portion having a bolt hole extending orthogonal to the longitudinal direction of the vehicle, and being fixable to the body of the vehicle by a fixing bolt inserted into the bolt hole;
- a fixing panel portion that expands in a lateral direction of the vehicle at right angles to the main panel portion is formed integrally with a front end of the main panel portion in the longitudinal direction of the vehicle, and being fixable to the power unit;
- and
- a pair of breaking grooves formed at an area located spaced away from the bolt hole so as to extend in respective radially outward direction of the bolt hole to an outer peripheral edge of the rear end of the main panel portion in the longitudinal direction of the vehicle, the respective radially outward directions are at an angle θ of 20°≦θ≦60° with respect to the longitudinal direction of the vehicle in which a load acts on the fixing bolt during vehicle collisions.
