Abstract

PURPOSE:To reduce the vibration due to engine revolution and widen the car interior space and simplify a power transmission mechanism by setting a crankshaft to be tilted in a horizontal plane with respect to right and left output shafts and arranging said crankshaft so that the both shaft lines are crossed each other. CONSTITUTION:An engine E is arranged in tilted form in a horizontal plane, and the axis line l1-l1 of a crankshaft 3 is crossed with the axis line l2-l2 of right and left output shafts 9r-9l at the cross angle alpha of 15-45 deg.. With such a constitution, the direction of variation of an engine driving torque is accorded with the direction of variation of the driving counter-torque which is applied onto right and left axles 2r and 2l by right and left front wheels Wr and Wl. Thus, amplification of the vibration of a chassis B can be prevented, and the fraught noise in a car interior can be reduced in a low-speed range including idling of the engine E. Further, an axle power transmission mechanism can be used in case the engine is arranged sideways, and thus constitution can be simplified, and the car interior space can be widened.

Generally, in a car, the engine is placed horizontally in the engine compartment of the car body (with the engine crankshaft perpendicular to the longitudinal direction of the car body), or vertically (the engine's crankshaft is placed perpendicular to the longitudinal direction of the car body). In the former case, a large effective space can be occupied within the vehicle interior, and a power transmission mechanism that connects the engine and the driving wheels is known. On the other hand, since the engine crankshaft and axle are approximately parallel to each other, the direction of engine torque variation and the direction of variation of the drive torque applied to the axle via the drive wheels match, and the engine This has the disadvantage of emphasizing vehicle body vibration due to rotation, and in the latter case, the engine crankshaft and axle are approximately orthogonal to each other, so the direction of engine torque fluctuation and the direction of the axle's driving reaction torque do not match. Although this can reduce the vibration of the vehicle body due to engine rotation, there are disadvantages in that the effective space within the vehicle interior becomes narrow and the structure of the power transmission mechanism connecting the engine and the drive wheels becomes complicated.
