Description of the Invention (1) [Technical Field] The present invention relates to a V-type internal combustion engine for locomotives; Arranged in the left-right direction, the crank shaft is centered, and the front and rear combination sections are opened in a V shape. The rear part of the crank case that houses the crank shaft is integrally connected with the transmission that houses the transmission. Improvement. [Advanced Technology] This V-type internal combustion engine for locomotive has been known as a motorcycle engine in the past (for example, refer to Japanese Patent Laid-Open No. 6-1 7 3 8 32). [Problems to be Solved by the Invention] In the past, the V-type internal combustion engine for the locomotive had a lubricating oil pump and a cooling water pump arranged in the up and down direction at the rear of the crank case. Therefore, it is not necessary to form the rear of the crank case too deeply. The interference of the transmission must protrude toward the rear of the crank shaft to protrude the transmission. This situation has led to an increase in the size of the internal combustion engine, making it difficult to ensure the ground height of the internal combustion engine and reduce the height of the rider's seat. The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a rear portion of a crank case and a transmission portion in a small size without interfering with a lubricating oil pump and a cooling water pump, thereby ensuring the ground height of the internal combustion engine or reducing the use for the rider. The seat height of the aforementioned V-type internal combustion engine for locomotives.

Description of the Invention (2) In order to achieve the above purpose, the present invention aims to In the state of being mounted on the body frame, the front and rear combination sections are opened in a V shape in the front and rear directions around the crank shaft arranged in the left-right direction. The rear part of the crank case that houses and holds the crank shaft is integrated. An internal combustion engine for a locomotive that is connected to a gearbox housing a speed gear, and is characterized by a lubricating oil pump that supplies lubricating oil to the lubricating part of the front and rear assembly parts, and cooling water that supplies water to the front and rear assembly parts. The set of cooling water pumps are arranged in the crank case, so that these pumps are arranged to the left and right in front and above the crank shaft. According to this first feature: since the oil pump and the water pump are arranged forward and above the crank shaft, the rear portion of the crank case and the transmission portion connected to the rear can be formed in a small size without interfering with the oil pump and the water pump, and It is possible to easily secure the ground height of the internal combustion engine and reduce the height of the rider seat. In this case, the above-mentioned arrangement of the oil pump and the water pump is used to form the shape of the front part of the crank case to some extent. The protruding part is also arranged in the dead space below the combined part, so it does not become a large internal combustion engine. Cause of change. A second feature of the present invention is that, in addition to the features described above, the lubrication oil pump and the cooling water pump are arranged coaxially, and both ends of a single pump shaft driven by the crank shaft at any time are connected to the pumps. According to this second feature: the oil pump and the water pump can be driven at any time by a crankshaft through a common drive train, and the purification of the drive train can be achieved. In addition, the drive system of the two pumps occupying a position higher than the crankshaft does not cause the oil to be impregnated into the crankcase oil collecting portion, so the oil is not stirred by the drive, and power loss can be reduced.

The heat of invention (19) affects the transmission section 95 and the transmission 8 ° housed in the transmission section of the section. [Starting system (refer to Figures 2 and 7)] On the crank A receiving recess 8 8 is formed on the front bottom surface of the box 21: The motor 11 is started there, and its axis is arranged parallel to the crank shaft 15. The casing 8 9 of the starter motor 11 has a cylindrical support portion 8 9 ′ a at one end tightly fitted into a through hole 90 formed in the end wall of the receiving recess 8 8, and is bolted 1 1 1 The mounting arm 8 9 b on the other end is coupled to the crank case 21 and thus is mounted to the crank case 21. The rotor shaft 9 1 of the starter motor 1 1 1 has its tip protruding into the crank case 21; a pinion 9 2 formed at the tip thereof drives the aforementioned starter gear through a reduction gear train 9 3. However, the starter gear 52, the overspeed clutch 53, and the reduction gear train 9 3 constitute a starter transmission device 9 4 that communicates between the starter motor 11 and the crank shaft 15. As described above, since the starter motor 11 is arranged in front of and below the crank shaft Γ5, the starter motor 11 does not prevent the rear part of the crank case 21 and the downsizing of the transmission part 95, and is absorbed into the front The front end space below the unit assembly 4 i does not hinder the miniaturization of the internal combustion engine E. In addition, with the above configuration of the starter motor 11, the reduction gear train 93 is immersed in the oil collecting section 66 of the bottom of the crank case 21, but this case is to actuate when the mechanism is started; The oil is not stirred so no power loss is caused. _ The present invention is not limited to the above embodiments, as long as the template paper dimensions that do not deviate from the main points are applicable to the Chinese national standard (CNS> A4 specification (210 X 297 cm)) — — — — — — — — — — — — — — — — — — ^ III — — — · C.
