Wherein, first belt pulley 10 can be fixed on the identical installation basis with tensioning support 40.Second belt pulley 20 can use first clamping bolt 61 to be fixed on the described identical installation basis by first fastener hole 21, and is fixed in tensioning support 40 by second clamping bolt 62.
When needs are regulated the tensioning degree of belt 30 (when for example pulley mechanism being installed or because of 30 loosening adjustings of belt after using a period of time time), being connected between loosening at first a little second belt pulley 20 and fixedly connected and second belt pulley 20 and the arc guide barrel 42 installed between the basis, just become flexible first clamping bolt 61 and second clamping bolt 62.Here, loosening second belt pulley 20 still is connected on the described installation basis by first clamping bolt 61 only for the operation of being convenient to subsequent adjustment, makes that second belt pulley 20 can be around 61 rotations of first clamping bolt.Simultaneously, second clamping bolt 62 moves with second belt pulley 20 along arc guide barrel 41.As shown in Figure 1, second belt pulley 20 turns clockwise, and required strap length diminishes between second belt pulley 20 and first belt pulley 10 with making, thereby loosens belt 30; Second belt pulley 20 is rotated counterclockwise and will makes strap length required between second belt pulley 20 and first belt pulley 10 become big, thereby tightens up belt 30.When the tensioning degree that makes belt 30 is adjusted to required degree, regulate operation as long as first clamping bolt 61 and second clamping bolt 62 tightened to finish once more.
Power-assisted steering pump assembly of the present invention comprises power-assisted steering pump 80 and second belt pulley 20 (being the drive pulley of power-assisted steering pump 80) that is installed on this power-assisted steering pump 80, this second belt pulley 20 is in transmission connection by first belt pulley 10 on belt 30 and the engine crankshaft, wherein: described power-assisted steering pump assembly also comprises the tensioning support 40 that is fixedly mounted on the motor body 70, this tensioning support 40 comprises the first side wall, is formed with arc guide barrel 41 on the described the first side wall; Described power-assisted steering pump 80 has the first axial fastener hole 21 and second fastener hole 22 that is parallel to described second belt pulley 20; First clamping bolt 61 is connected to motor body 70 by described first fastener hole 21 with described power-assisted steering pump 80; Second clamping bolt 62 can be fixed to described tensioning support 40 with described power-assisted steering pump 80 adjustable grounds by described arc guide barrel 41 and described second fastener hole 22.
Similarly, when needs are regulated the tensioning degree of belt 30 (when for example pulley mechanism being installed or because of 30 loosening adjustings of belt after using a period of time time), being connected between fixedly connected and second belt pulley 20 between loosening at first a little second belt pulley 20 and the motor body 70 and the arc guide barrel 42, just become flexible first clamping bolt 61 and second clamping bolt 62.Here, loosening second belt pulley 20 still is connected on the described installation basis by first clamping bolt 61 only for the operation of being convenient to subsequent adjustment, makes that second belt pulley 20 can be around 61 rotations of first clamping bolt.Simultaneously, second clamping bolt 62 moves with second belt pulley 20 along arc guide barrel 41.As shown in Figure 1, second belt pulley 20 turns clockwise, and required strap length diminishes between second belt pulley 20 and first belt pulley 10 with making, thereby loosens belt 30; Second belt pulley 20 is rotated counterclockwise and will makes strap length required between second belt pulley 20 and first belt pulley 10 become big, thereby tightens up belt 30.When the tensioning degree that makes belt 30 is adjusted to required degree, regulate operation as long as first clamping bolt 61 and second clamping bolt 62 tightened to finish once more.
Wherein, second belt pulley 20 can be realized around 63 rotations of first clamping bolt by variety of way, for example manually rotate second belt pulley 20, but this mode may cause adjusting accurate inadequately.Therefore, preferably, described power-assisted steering pump assembly also comprises flexible connection piece 50, described flexible connection piece 50 has two mutual vertical and disjoint tapped hole 51 and 52, described tensioning support 40 also comprises second sidewall vertical with described the first side wall, have through hole 42 on this second sidewall, described two tapped holes 51 and 52 are aimed at described arc guide barrel 41 and described through hole 42 respectively; Described tapped hole 51 and described second fastener hole 22 that described second clamping bolt 62 passes described arc guide barrel 41, the described arc guide barrel 41 of aligning successively are fixed to described tensioning support 40 with described second belt pulley, 20 adjustable grounds; The described tapped hole 52 that tensioning bolt 65 passes described through hole 42 and the described through hole 42 of aligning is connected in described flexible connection piece 50.
Can make things convenient for, accurately regulate the tensioning degree of belt 30 by this layout.Specific operation are as follows, and equally at first loosening first clamping bolt 61 and second clamping bolt 62 make that second belt pulley 20 and power-assisted steering pump 80 can be around 61 rotations of first clamping bolt.Rotate tensioning bolt 65 then.Because second belt pulley 20 and tensioning support 40 still are connected in motor body 70, thereby flexibly connect piece 50 and tensioning bolt 65 and form and be similar to the feed screw nut driving mechanism.In other words, rotating tensioning bolt 65 will make flexible connection piece 50 that linear moving taken place.Thereby second belt pulley 20 rotate with flexibly connecting moving of piece 50, and make second clamping bolt 62 with second belt pulley 20 with flexibly connect moving of piece 50 and move along arc guide barrel 41.
Therefore, can be by make second belt pulley 20 clockwise or be rotated counterclockwise along different direction rotation tensioning bolt 65, to unclamp or tightening belt 30.This rotation significantly that is actually by tensioning bolt 65 causes second belt pulley 20 that rotation by a small margin takes place, thereby can accurately control the adjusting to second belt pulley, 20 positions.
Here, it should be noted that, in the linear moving process that flexibly connects piece 50, the size of arc guide barrel 41 should be able to make first tapped hole 51 aim at the notch of arc guide barrel 41 all the time, is not displaced to this notch zone in addition and can not move because of the linearity that flexibly connects piece 50.Particularly, can make the aperture of the width of arc guide barrel 41 greater than first tapped hole 51.
Arrange for convenience and make second belt pulley 20 that small rotation can be regulated belt 30 in a big way tensioning degree take place that preferably, described first fastener hole 21 and described second fastener hole 22 are symmetrical arranged with the axis of described second belt pulley 20.As depicted in figs. 1 and 2, first fastener hole 21 and second fastener hole 22 are positioned at second belt pulley about in the of 20 both sides.
