Title:
TRANSMISSION MOUNT STRUCTURE OF VEHICLE
Document Type and Number:
Japanese Patent JP3949549
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To attain both a reduction in vibration in a vertical direction of a power source comprising an engine and a transmission and a reduction in vibration in a rolling direction of the power source.
SOLUTION: A transmission lower mount 37 fixed to a transmission is constructed such that the end part of the transmission is provided with a main mount rubber 56 and a sub-mount rubber 57 smaller than the main mount rubber 56 and extending in a roll direction to be substantially orthogonal, and a middle part of the sub-mount rubber 57 in its longitudinal direction is provided with a small sectional part 75 having a small sectional area. A spring constant of the power source in its rolling direction is made small by the small sectional apart of the sub-mount rubber to enable a rolling vibration of the power source to be prevented from being trnasmitted to a vehicle body at the time of idling or acceleration or deceleration. Since the spring constnat in a vertical direction is kept in its high value by the main mount rubber and the sub-mount rubber, so that a vibration of the power source in a low frequency range is restricted from being transmitted to the vehicle body to enable a reduction in comfortable feeling in riding on a vehicle to be prevented.
