Embodiment Construction

[0025] Figure 1 is a schematic diagram showing the structure of the engine-transmission assembly.

[0026] The engine 1 is equipped with a cylinder head 1a, a cylinder block 1b, and an oil pan 1c. Although the engine 1 adopts a V-shaped design in this embodiment, naturally, the engine 1 may also adopt an in-line design. The cylinder head 1a is mounted on the cylinder block 1b. The oil pan 1c is connected to the cylinder block 1b. In this specification, the term "engine cylinder block" refers to a combination of a cylinder block 1b and an oil pan 1c. It is also possible to manufacture the cylinder block 1b and the oil pan 1c as a single piece.

[0027] The automatic transmission 2 is connected to the engine 1. One end of the transmission case 2a and one end of the engine 1 are connected together by, for example, bolts (at the position indicated by the reference numeral 1d in FIG. 2). A portion 100 of the transmission side end surface (110, 120) of the engine cylinder block partiall...

Abstract

A starter mounting structure for a starter for cranking an engine (1) has a transmission case (2a) surrounding the transmission (2) and having an engine side end surface (200) facing an engine side. The engine block (1b) has a transmission side end surface (110, 120) facing a transmission side and partially overlapping the engine side end surface (200) of the transmission case (2a). An outer periphery (140) of the transmission side end surface (110, 120) of the engine block is partially equipped with a recess which extends on a crankshaft (5) side with respect to an inner periphery (240) of the engine side end surface (200) of the transmission case. An opening portion (13) is formed in correspondence with the recess. The starter mounting structure has a starter mounting member (9) closing the opening portion (13) and supporting the starter (8).

Description

Technical field [0001] The invention relates to a mounting structure for an engine starter. Background technique [0002] The engine starter is usually installed near the connecting part that connects the engine and the transmission. The pinion gear arranged in the starter meshes with a ring gear arranged on the outer peripheral surface of a drive disc or flywheel, which is arranged at the end of the crankshaft. By rotating the ring gear, the starter starts the engine. [0003] In an automatic transmission, a drive disc provided at the end of the crankshaft of the engine is fastened to a torque converter provided at one end of the input shaft of the transmission by means of bolts or the like. This type of tightening operation usually requires an operating space. [0004] However, since various accessories are connected to the engine and the transmission, such operating space is subject to various restrictions. In particular, in order to achieve an effective seal between the engin...
