Shown in Fig. 4 to 6, tension-adjusting gear 80 comprises guide wheel arm 82, guide wheel bracing frame 86 and tension adjustment screw 87.Guide wheel arm 82 rotatably is inserted on the outer peripheral face of wheel hub sleeve 61 by a bearing 81.One end of guide wheel arm 82 is connected in the end that power is inserted into guide wheel bracing frame 86 slidably by means of bolt 83 and nut 84.The other end of guide wheel bracing frame 86 is connected on the cylinder block of driving engine by a plurality of bolts 85.Tension adjustment screw 87 is inserted in the guide wheel bracing frame 86 along the opposite sense that guide wheel arm 82 inserts guide wheel bracing frame 86.Tension adjustment screw 87 is regulated the tension force of driving band 31 by the restriction of guide wheel arm 82 being inserted guide wheel bracing frame 86 degree of depth.
Guide wheel arm 82 comprises a housing connecting portion 821, and it is fixed on the wheel hub sleeve 61 by bearing 81.Rectangular shaft portion 823 stretches out from housing connecting portion 821 one, and it has bolt hole 823a, and bolt 83 can be inserted in this hole.
Guide wheel bracing frame 86 comprises a bar portion connecting portion 861, and it has a work nest 861a so that the bar portion of guide wheel arm 82 823 inserts wherein and can slide here, and tension adjustment screw 87 passes bar portion connecting portion 861 with bolt 83 and links to each other with bar portion 823.One end of driving engine connecting portion 863 and bar portion connecting portion 861 monolithic moldings.The other end of driving engine connecting portion 863 bends towards the cylinder block of driving engine (E) and links to each other with cylinder block by a plurality of bolts 85.
Bolt hole 823a in the bar portion 823 is a slotted hole, and it prolongs along the moving direction of bar portion 823 in work nest 861a.
Because driving engine connecting portion 863 overall fixed of guide wheel bracing frame 86 are on the cylinder block of driving engine (E), therefore the guide wheel 32 that is supported by guide wheel bracing frame 86 is easy to just can align with the crankshaft pulley 2 of driving engine.In embodiments of the present invention, no matter how driving engine moves, and guide wheel 32 remains with crankshaft pulley 2 and aligns.
For safety, be installed in the common all the place aheads of oblique car body of driving engine (E) on the automobile rear vehicle body frame.Crankshaft pulley 2 have one with driving engine (E) oblique angle identical, that turn forward.
Corresponding to the oblique angle of crankshaft pulley 2, guide wheel 32 also wing drop so that keep aliging with crankshaft pulley 2.
No matter how the S. A. of guide wheel 32 tilts, and the power between guide wheel 32 and the cooling fan 20 all can transmit reposefully by power transmission, and the S. A. of cooling fan 20 remains static simultaneously.
Guide wheel 32 is by the driving engine integrated support.Change in location between guide wheel 32 and the cooling fan 20 can be absorbed by cover yoke 61a, axle yoke 62a and cross joint 63.
The driving engine of making thus can be installed on the car body with various angles according to different automobile types, and the heat sink assembly that has cooling fan simultaneously can be installed on the diverse location of driving engine.In addition, the vibration that produces in car running process between heat sink assembly and the driving engine is very steady, and power transmits very quiet.
In one embodiment of the invention, between crankshaft pulley 2 and the guide wheel 32 and a constant alignment angle is arranged, thereby can prevent to connect on the driving band 31 of guide wheel 32 and crankshaft pulley 2 the transmission resistance appears.The efficient that the life-span of belt and power transmit is able to further raising.
Cooling fan 20 faces the suction direction of extraneous air when mounted, and this extraneous air is from the opening portion of car body side plate side overhang-door 24.Can improve the suction efficiency of extraneous air like this and further improve cooling effectiveness.
The tension adjustment of driving band 31 is as follows.
When between crankshaft pulley 2 and guide wheel 32, still coupling together, be used for connecting the bolt 83 and loose connection of nut 84 maintenances of guide wheel arm 82 and guide wheel bracing frame 86 without driving band 31.
Thereby guide wheel 32 is pulled to crankshaft pulley 2 to be connected to driving band 31 on the bent axle.Guide wheel 32 can pull to crankshaft pulley 2 through cover yoke 61a, axle yoke 62a and cross joint 63.
In case driving band 31 is connected on crankshaft pulley 2 and the guide wheel 32, just can thereby being separated with guide wheel bracing frame 86 slidably, guide wheel arm 82 make driving band 31 keep correct tension force towards a direction rotation tension adjustment screw 87.
Microscler bolt hole 823a on the guide wheel arm 82 can make guide wheel arm 82 slide along the work nest 861a of guide wheel bracing frame 86.
After driving band 31 correct maintenance tension force, bolt 83 and nut 84 are tightened up, thereby tension adjustment is finished in 82 motions of restriction guide wheel arm.
Can find out from the front, the invention has the advantages that when engine is installed on the automobile, Crankshaft pulley and guide wheel can automatic alignings. Simultaneously can stably keep the state of this alignment, Thereby can reduce the driving resistance of dynamic conveyor belt, and further improve life-span of belt and moving The power transmission efficiency.
