Embodiment
Below, with reference to Fig. 1～Fig. 3, embodiment of the present utility model is described.
In description of the present embodiment, fore-and-aft direction is the axle direction (directions X) of the bent axle 200a of mean engine 200, and automatic transmission 300 sides described later are used as rear side.In addition, in Fig. 1, with imaginary line (double dot dash line), represent automatic transmission 300 etc.
First, motor (internal-combustion engine) the 200th, is installed in FR(front-mounted engine rear wheel drive) motor in vehicle, the rear side of this motor 200 disposes automatic transmission 300(speed change gear).Motor 200 connects as one with automatic transmission 300, and power plant P is comprised of this motor 200 and automatic transmission 300.
In the end (rearward end) of the axle direction (directions X) of the bent axle 200a of motor 200, be provided with can with the drive plate 210 of bent axle 200a one rotation, the rotating power of this drive plate 210 is passed to automatic transmission 300.
Torque-converters is known device, not shown at this, and it comprises the pump impeller of input shaft side, the guide wheel of the turbine of output shaft side, performance moment of torsion amplification function and overrunning clutch etc., above-mentioned pump impeller with front shroud 310(with reference to Fig. 1) be connected.Fastening by bolt etc. between the front shroud 310 of this torque-converters and above-mentioned drive plate 210, the rotating power of the bent axle 200a of motor 200 is passed to the pump impeller of the front shroud 310(input shaft side of torque-converters by drive plate 210).These torque-converters and gear portion are housed in transmission case 301.
In addition, relevant speed change gear, also can adopt the speed change gear that gear ratio is carried out to the alternate manners such as stepless speed variator (CVT:Continuously Variable Transmission) of step-less adjustment.
And, between the transmission case 301 of the cylinder block 201 of above-mentioned motor 200 and crankcase 1 and automatic transmission 300, by bolt etc., be connected, and form above-mentioned power plant P.Power plant P is supported on car body by engine support (not shown).So, by with engine support supporting motive force device P, can make vibration (the caused vibrations such as rotation change that produce with the change of the output torque of the motor 200) decay of these power plant P.In addition, in present embodiment, in order to reduce the vibration of engine support, the resonant frequency of power plant P is set highlyer (power plant resonance improves).That is, power plant resonance raising can bring the effect that reduces vibration.
Below, with reference to Fig. 1～Fig. 3, crankcase 1 is described.
Crankcase 1 is connected the bottom of cylinder block 201 by bolt etc.In the bottom of this crankcase 1, by bolt etc., connecting oil sump 203.
As shown in Figures 2 and 3, in the bottom of crankcase 1, be provided with for being communicated with the opening 11 of oil sump 203.In addition, in the bottom of crankcase 1, be provided with opening 12 for terminal operation.This terminal operation is openings of rectangle with opening 12, be arranged on the abutted surface 10 that joins with transmission case 301 near.Terminal operation is provided with for the plate assembly department 14 of gusset plate 2 described later is installed with the edge of opening 12.On this plate assembly department 14, be processed with a plurality of (being in this embodiment 4) interior threaded hole 14a.These interior threaded holes 14a is configured on the position corresponding with the bolt insertion hole 2a of gusset plate 2.
In addition, the end wall of end wall 1a(automatic transmission 300 sides of crankcase 1) be provided with the intercommunicating pore 13 of rectangle.After crankcase 1 is connected with transmission case 301, this intercommunicating pore 13 is used as at the terminal operation of the uses such as the inside of transmission case 301 insertion tool and uses hole.Under the state not covered by gusset plate 2 described later with opening 12 at terminal operation, intercommunicating pore 13 is used opening 12 by terminal operation and is communicated with the outside of crankcase 1.
By opening 12 and intercommunicating pore 13 for terminal operation is set like this on crankcase 1, can, after automatic transmission 300 being connected on cylinder block 201 and crankcase 1, utilize the front shroud 310 of opening 12 and the fastening drive plate 210 of inserting hole 13 and torque-converters for these terminal operations.
Yet, if there is opening 12 for terminal operation in the bottom of crankcase 1, when power plant P twists resonance (resonance being caused by rotation of motor 1 etc.), can there is shear deformation in the part (being provided with the part of opening 12 for terminal operation) as the downside of the crankcase 1 of the contact segment between crankcase 1 and automatic transmission 300, the torsional rigid of power plant P is reduced, thereby the effect that above-mentioned power plant resonance is improved reduce.Under this situation, the vibration of engine support can increase, and the noise that imports the motor in car into just can increase.
In order to address the above problem, in present embodiment, as shown in Figures 2 and 3, and on crankcase 1, the gusset plate 2 of the shear deformation that installation covering terminal operation is produced with inhibition crankcase 1 with opening 12.
Gusset plate 2 is for example the member of being made by the contour rigid material of aluminum or aluminum alloy, and it is processed to cover the rectangle of opening 12 for above-mentioned terminal operation.Four corner portions located of gusset plate 2 are not provided with bolt and insert universal hole 2a.
Utilize above-mentioned terminal operation with opening 12 and inserting hole 13 drive plate 210 and torque-converters is fastening after, gusset plate 2 is installed, make it cover opening 12 for terminal operation.Particularly, gusset plate 2 is configured in to the plate assembly department 14 of crankcase 1, simultaneously by the interior threaded hole 14a of each bolt insertion hole 2a difference alignment sheets assembly department 14 of gusset plate 2.Under this state, bolt 3 is inserted in each bolt insertion hole 2a of gusset plates 2, and each bolt 3 is screwed in the interior threaded hole 14a of plate assembly department 14 and gusset plate 2 is installed on to crankcase 1.
So, by gusset plate 2 is installed on to crankcase 1, can improve the rigidity of the part of opening 12 for terminal operation that offers of this crankcase 1, thereby improve the torsional rigid of power plant P.Thus, can suppress power plant P when resonance shear deformation of producing of crankcase 1 that twists, reduce the vibration of engine support, thereby lower, import the engine noise in car into.In addition, by covering opening 12 for terminal operation with gusset plate 2, can also prevent that dust etc. from entering in crankcase 1.
In addition, the utility model is also applicable to be installed in the front-wheel drive of FF(front-mounted engine) power plant that form of motor in vehicle and speed change gear.
