Problems solved by technology

However, since the spring constant in the rotational direction of the elastic vibration isolator also increases with the increase of the horizontal sectional area of ​​the elastic vibration isolator, it is no longer possible for the mounting element 107 to effectively reduce the vibration and displacement in the rotational direction
Thus, it is difficult to obtain a good combination of vertical and rotational spring constants

Embodiment Construction

[0020] see now in particular figure 1 , figure 1 Shown is a top view of the interior of an engine compartment in which a power unit 13 is mounted using a mounting system including a gearbox mounting structure of the present invention. The vehicle power unit 13 includes a transversely installed engine 10 and a gearbox 11 connected to the output end of the engine 10 or integrally assembled. Although not shown, engine 10 has a crankshaft extending in the lateral direction of the vehicle. The engine 10 and gearbox 11 assembled above are supported by the subframe 12 and the left and right front side frames (only the left front side frame is shown and indicated by reference number 15 ).

[0021] The subframe 12 is formed by connecting the following members: left and right longitudinal subframe elements 21, 22 extending in the longitudinal or front-to-rear direction of the vehicle, respectively connected to the longitudinal subframe elements 21, 22 at their front and rear ends The...

Abstract

A transmission mount structure for mounting a transmission connected to an end of a transverse-mounted engine to a vehicle body includes an elastic main vibration-damping member for reducing both vibrations in a vertical direction and vibrations in a roll direction, and an elastic auxiliary vibration-damping member smaller in diameter or thickness than the main vibration-damping member and extending in a direction substantially perpendicular to the roll direction. The auxiliary vibration-damping member has a constricted portion formed at a longitudinal central portion thereof and having a smaller cross-section than any other part of the auxiliary vibration-damping member.

Description

technical field [0001] The present invention relates to an improvement of a vehicle transmission mount structure. Background technique [0002] Various vehicle transmission mounting structures are known in which the transmission is supported at a single point and the engine constituting the power unit of the vehicle together with the transmission is supported at two points. An example of such a known gearbox mounting structure is disclosed in Japanese Patent Application Laid-Open No. Hei-10-309945. [0003] As shown in Figure 7, the disclosed gearbox mounting structure includes: a mounting element 107, one end of the mounting element 107 is connected to a mounting bracket 103 connected to one end of the gearbox 101, and the other end is connected to a mounting bracket 104 connected to the vehicle chassis frame 104. Attached mounting bracket 108 . The gearbox 101 is connected to the output of a transversely mounted engine 100 . A mounting element 105 is connected to the fr...
