The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
Present embodiment comprises: 1, left slide rail, 2, left socle, 3, bolt, 4, the flexible axle fixed head, 5, right slide rail; 6, right support, 7, bearing pin, 8, the cylinder pulley, 9, cottor pin, 10, the junction plate I; 11, circular cone pulley, 12, upper plate, 13, lower plate, 14, the junction plate II, 15, the equalizer drag-line; 16, preceding movable window, 17, preceding movable window roller, 18, the equalizer roller, 19, the equalizer connecting rod.
The present invention includes left slide rail 1, flexible axle fixed head 4, right slide rail 5; Left side slide rail 1, right slide rail 5 are welded on the driver's cabin both sides respectively; Flexible axle fixed head 4 is welded on left slide rail 1 rear end, and left socle 2 is positioned at the leading portion and the epimere bending part of left slide rail 1, and right support 6 is positioned at the leading portion and the epimere bending part of right slide rail 5; Before preceding movable window roller 17 on the movable window 16 be to be connected with right slide rail 5 with left slide rail 1; One end of balance drag-line 15 is connected with preceding movable window 16, and described left slide rail 1 epimere slideway is the level of state, and deviation is in ± 5 ° of scopes; Described right slide rail 5 epimeres are the level of state, and deviation is in ± 5 ° of scopes, also can stay open state when this technical scheme can make movable sash lock decide failure of apparatus.
The leading portion of described left slide rail 1 and epimere bending part slideway soffit gap C, the leading portion of described right slide rail 5 and epimere bending part slideway soffit gap C are convenient to installation and removal activity window.
The left socle 2 that the sealing breach is arranged at the leading portion and the epimere bending part slideway soffit gap place of described left slide rail 1; At the right support 6 that there is the sealing breach at the leading portion and the epimere bending part slideway soffit gap place of described right slide rail 5, keep the continuity of slideway.
The forward and backward two ends of described left socle 2 are separately installed with cylinder pulley 8; In the centre of left socle 2 circular cone pulley 11 is installed; The balance drag-line 15 that is connected with flexible axle fixed head 4 is that the surface with cylinder pulley 8 and circular cone pulley 11 joins, and the conicle end small end of described circular cone pulley 11 is in the bottom of chute.Support assembling pulley, the frictional force of minimizing drag-line, the pulley at left socle two ends is cylindrical, and is tangent with the slideway surface, avoids equalizer drag-line and left slide rail gap edge to produce scraping, the damage drag-line.The left socle intermediate pulley is conical, makes the equalizer drag-line can upwards not produce play at pulley spindle, has avoided drag-line and movable window roller stuck.
All there is flange described left slide rail 1, right slide rail 5 both sides, and wherein upper overturning A1 becomes 90 degree with the slideway surface, following flange A2 and the applying of slideway soffit, and the employing turnup structure has increased the intensity of left and right slide rail.
There is buffering bending D described left slide rail 1, right slide rail 5 lower ends, play cushioning effect.
Described balance drag-line 15 has equalizer connecting rod 19 with preceding movable window 16 junctions, movable window roller 17 and equalizer roller 18 before being hinged with on the equalizer connecting rod 19.
The concrete implementation of present embodiment is:
The right side slide rail is made up of right slide rail 5, right support 6, and is as shown in Figure 2.Left side slide rail 1, right slide rail 5 are welded on the driver's cabin both sides respectively, and flexible axle fixed head 4 is welded on left slide rail 1 rear end, and left socle 2, right support 6 are fixed on the driver's cabin with bolt 3 respectively, and cooperate closely with slide rail, and slideway is kept continuously.
A left side slide rail 1, right slide rail 5 bilateral symmetry adopt cold stamping shapedly, have flange up and down, and are as shown in Figure 8, gain in strength.Slide rail epimere level, there is the bending of the cushioning effect of playing the lower end, and epimere and leading portion bending part have opening, are convenient to the assembling activity window, and be as shown in Figure 7.
Before movable window 16 profiles are rectangles, four jiaos are equipped with roller 17, roller can freely rotate, and is shown in figure 12.Equalizer drag-line 15 ends are connected with equalizer roller 18, and equalizer roller 18 is connected with preceding movable window through equalizer connecting rod 19, and all connections all are hinged, can freely rotate, like Figure 12, Figure 13, shown in Figure 16.Before movable window 16 be assemblied in the chute of left slide rail 1 and right slide rail 5, preceding movable window roller 17 is pasting detent surface and is rolling, movable window is dug and closed before the realization, and is shown in figure 11.Equalizer is connected with preceding movable window 16 through drag-line 15, pulley 18, connecting rod 19; Preceding movable window 16 is remained effect sizeable pulling force upwards; Make leicht fallen D/A when opening window, can be when closing window owing to the window self gravitation does not impact downwards, like Figure 14, shown in Figure 16.Slide rail 1 bending part assembling left socle 2 in a left side is equipped with cylinder pulley 8 and circular cone pulley 11 on the left socle 2, equalizer drag-line 15 is attached to the surface of pulley all the time; During equalizer drag-line 15 motion, with pulley be rolling friction, therefore; Can not lose efficacy, like Fig. 5, Fig. 6, shown in Figure 15 because of wearing and tearing.Do not arrange equalizer drag-line 15 in the right slide rail 5, therefore, right support 6 does not have pulley.
