Abstract

PURPOSE:To improve the transmission efficiency by arranging a cylinder bank which is inclined forwardly before and behind and meshing a drive gear on each crankshaft with a driven gear on a countershaft and interposing a transmission gear mechanism onto a countershaft and a drive shaft arranged in a prescribed relation. CONSTITUTION:In an engine unit 11 consisting of the cylinder banks 17a and 17b arranged before and behind, primary drive gears 19a and 19b are fixed onto the crankshafts 18a and 18b of the cylinder banks 17a and 17b. The gears 19 and 19b are meshed with a primary driven gear 21 on a single countershaft 20. The drive gear bank 22 of a transmission gear mechanism is installed onto the countershaft 20, and meshed with the driven gear bank 24 on a contiguous drive shaft 23. The cylinder banks 17a and 17b are arranged in the forward inclination by a prescribed angle, and a flat surface Ba connecting the axis centers of the countershaft 20 and the drive shaft 23 is set so as to pass through the vicinity of a front crankshaft 18a between the front and rear crankshafts 18a and 18b.

エンジンに関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) This invention relates to a multi-cylinder engine with a mission, such as a two-wheeled motor vehicle, which is assembled with two front and rear crankshafts, such as a square 4 engine.

ライブ軸３に伝えるようになっている。In this basic layout, as shown in Fig. 3, the crankshaft 1, counter@2, and drive shaft 3 are arranged side by side, with the primary drive gear 4 near the crankshaft and the primary driven gear 5 of the counter it 2Il. A drive gear train 6 and a driven gear train 7 of a mission gear mechanism are interposed between the counter shaft 2 and the drive shaft 3, and the rotation of the crankshaft 1 is transmitted to the drive shaft 3 at the required shifted speed stage. It looks like this.

It is desirable that the axes of the two be aligned on the same plane A as much as possible.

理論的には理想的である。On the other hand, some multi-cylinder engines have a front cylinder row crankshaft and a rear cylinder row crankshaft arranged side by side, such as a square four engine in which four cylinders are arranged in a rectangular arrangement. In this case, as shown in FIG. 4, a primary drive gear 4a,
4b is fixed and injected into the primary driven gear 5, so in terms of conduction efficiency, the plane B connecting the counter shaft 2 and drive shaft 3 centers is the center line of the plane C connecting both crankshafts 1a and Ib axes. Theoretically, it would be ideal for the rails to pass through the rails.

じる。However, in such a layout, the drive shaft 3 is located low and the mission driven gear train 7 collects oil, which is a practical problem and makes the mechanical system and lubrication system unstable.To avoid this, the entire engine If the drive shaft is tilted forward and the drive shaft is raised, the front-rear length will become too long, which will impair the balance and appearance of the vehicle.

的とする。(Problems to be Solved by the Invention) As described above, multi-turbine engines with transmissions that can be installed in motorcycles, etc., and equipped with two crankshafts have good conduction efficiency and a well-balanced installation. ,
In view of the problem that it is difficult to create a conduction system that has a good appearance, this invention aims to provide a transmission system for motorcycles and other vehicles that has excellent conduction efficiency and can be mounted in a balanced and good-looking mounting position. The purpose is to provide a multi-cylinder engine.

た構成になるものである。(Means for Solving the Problems) In order to achieve the above object, in the multi-cylinder engine with a transmission for motorcycles and the like according to the present invention, the crankshaft of the moe cylinder row and the crankshaft of the rear cylinder row are arranged in front and behind each other! The primary drive gear, which has 112 stages and is fixed to both crankshafts, meshes with the primary driven gear on the countershaft.
In a multi-cylinder engine with a mission such as a VJ two-wheel vehicle in which a mission gear mechanism is interposed between the counter shaft and the drive shaft, the plane connecting the axes of the counter shaft and the drive shaft is the front crankshaft between the front and rear crankshafts. The arrangement is such that the cylinder row is mounted so as to be tilted forward.

減し、潤滑系が安定する。(Function) With this configuration, the position of the drive shaft is raised without making the cylinder part tilt forward that much, and the mission driven gear train is raised above the A-ile surface of the mission chamber, allowing oil to be scraped. This reduces mechanical loss and stabilizes the lubrication system.

することができる。Additionally, the vertical width of the transmission chamber is shortened by the length of the drive shaft, allowing the center of gravity of the engine to be lowered. At the same time, the forward inclination of the cylinder part is small and it can be easily moved, so the engine can be mounted in a well-balanced manner without increasing the front-to-back length of the engine, and in combination with the above-mentioned reduction in vertical width, the engine part is not exposed like in a motorcycle. The appearance of the mounting position can be improved if the

。In addition, since the plane connecting the axes of the countershaft and drive shaft is set to pass between both crankshafts, both primary drive gears mesh with the primary driven gear on both sides of that plane, which improves conduction efficiency. There is almost no loss.
