Abstract

PURPOSE:To ensure high rigidity and high natural frequency by forming the wall thickness of the engine-side installing portion of a reinforcing member on the longer side up to an end bolt fastening portion on an engine center line which extends in the vertical direction through a crankshaft axis, larger than that on the narrower side. CONSTITUTION:A pair of engine side installing members 10a, 10b which are formed in a U-shape section while being fastened with bolts and a transmission side installing member 4 which is fastened to a transmission from a crankshaft direction with bolts are provided on an engine-transmission joining/reinforcing member 3. The wall thickness of the engine side installing member 10a on the longer side up to an end bolt fastening portion on an engine center line which extends in the vertical direction through a crankshaft axis while being within the bolt fastening range connecting bolt fastening portions around a crankshaft of a transmission side installing member 4, is formed larger than that of the installing member 10b on the narrower side. Further, a cut-off portion 7 is formed on the reinforcing member 3. By such a structure, rigidity can be improved while improving natural frequency.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an engine-transmission coupling reinforcing member suitable for use in a horizontally mounted engine mounted on a front-wheel drive vehicle or the like.

(Prior art) In a horizontally mounted engine installed in a front-wheel drive vehicle, etc.,
The transmission is connected in series to the side of the horizontally placed engine body, and the transmission side supports the differential by integrally holding the drive shaft center (crankshaft) on the engine body side and its blade side. The drive shafts (output shafts) are arranged parallel to each other and eccentric to each other. For this reason, a large bending moment is applied to the joint between the engine body and the transmission, so this joint is generally reinforced with a reinforcing member.

(Problem to be Solved by the Invention) In the above-mentioned horizontally mounted engine, the center of gravity of the transmission, which is arranged in series on the side of the engine body, is located at the center of gravity of the differential, which is arranged so as to be held on the side of the transmission. The position of the center of gravity of the transmission was determined by the installation position of the output shaft, and generally the center of gravity of the transmission did not coincide with the axis of the crankshaft, but was offset to the left or right with respect to the crankshaft. For this reason, the strain energy generated in the reinforcing member due to vibrations during engine operation has different magnitudes with respect to the cylinder axis of the engine body (on the left and right sides of the crankshaft).

In addition, under the arrangement described above, the attachment part on the transmission side of the reinforcing member that spans between the engine body and the transmission will interfere with the differential installed adjacent to the side of the transmission. In such a case, the attachment range (bolt fastening area) of the transmission side attachment part to the transmission will be different between the interfering side and the non-interfering side with respect to the cylinder axis of the engine body (left and right of the crankshaft). In addition to the distribution of strain energy based on the above-mentioned weight distribution, the required strength of the reinforcing member is asymmetrical with respect to the cylinder axis from the viewpoint of the mounting structure.

In addition, as mentioned above, reinforcing members tend to generate large vibrations due to different vibration modes between the engine body side and the transmission side due to eccentricity between the engine body side crankshaft and the transmission side output shaft, and furthermore, the power steering pump,
Coupled with the resonance phenomenon with auxiliary equipment such as near compressors,
There was also the possibility that it would increase noise inside the vehicle and have a negative impact on auxiliary machinery.

Furthermore, in horizontally mounted engines, the reinforcing member located below the engine may interfere with the exhaust pipe located at the same position, and in this case, a notch is formed in the reinforcing member to prevent interference. It happens.

In order to improve the rigidity of the reinforcing member as a whole and ensure a high natural frequency, measures such as forming beads at appropriate positions on the reinforcing member or bending the edges of the notch can be taken to deal with such situations. However, even if these measures are taken, they are not necessarily sufficient, and it is desired to ensure even higher rigidity and a higher natural frequency.
