Abstract

A transmission assembly structure includes an engine-side joining surface, a transmission-side joining surface, which is joined to the engine-side joining surface, an engine component which is provided on an outside of the engine-side joining surface in a radial direction in the flywheel housing and protrudes toward the transmission side, a guide member which is provided on the engine-side joining surface or in the vicinity of the engine-side joining surface of the flywheel housing and in a vicinity of the engine component and which protrudes toward the transmission side further than the engine component, and a guide hole, which is provided on the transmission-side joining surface of the transmission housing or in the vicinity of the transmission-side joining surface and into which the guide member is inserted.

Dependent claims

A transmission assembly structure comprising:

an engine-side joining surface, which is formed on a flywheel housing of an internal combustion engine;
a transmission-side joining surface, which is formed on a transmission housing of a transmission and is joined to the engine-side joining surface;
a power steering pump, which is provided on a position farther away from a rotation axis of a flywheel than the engine-side joining surface in a radial direction and which protrudes toward a transmission side with respect to the engine-side joining surface;
a concave portion formed in an outer peripheral portion of the engine-side joining surface and recessed inward in a radial direction perpendicular to the rotation axis of the flywheel, the power steering pump disposed in the concave portion;
two bolt holes, which are provided on the engine-side joining surface closer to the rotation axis of a flywheel than the power steering pump and immediately approximated to the power steering pump;
a guide member, which is provided on the engine-side joining surface or in a vicinity of the engine-side joining surface of the flywheel housing and also in a vicinity of the power steering pump between the two bolt holes and which protrudes toward the transmission side further than the power steering pump with respect to the engine-side joining surface;
and
a guide hole, which is provided on the transmission-side joining surface or in a vicinity of the transmission-side joining surface of the transmission housing and into which the guide member is inserted.
