Abstract
The utility model relates to a full-hydraulic steering bridge which has the main technique structure that adopts a two-way oil cylinder (2) which is arranged transversely is fixedly connected with a bridge body (9), and a floatable leading slide block (1) is arranged on the end of a piston rod (10) of the oil cylinder; the slide block (1) is connected with a draw rod (5) and a steering node (8) through a ball head pin (4). When a wheel makes a turn, the leading slide block (1) which has the floating function can automatically adapt the change of space force when the ball head pin (4) rotates, and radial force relative to the oil cylinder is enabled to act on a guiding rail (3), and thereby, the utility model lightens the radial stress of the piston rod, reduces the abrasion of a cylinder sleeve and a sealing ring and basically eliminates the leakage of hydraulic oil and the loss of pressure.
Description
The utility model relates to a kind of hydro-steering bridge, is applicable to industrial wheeled handling machinery.
The wheeled handling machinery of industry often works in environment such as harbour, warehouse, workshop, requires to have less Turning radius to turn to freely in the narrow place being adapted at.Be used for this type of steeraxle mechanically and mainly contain chevron shaped steeraxle and horizontal two-way cylinder steeraxle at present, these two kinds of bridges can both be accomplished bigger steering angle.But its structure of chevron shaped steeraxle is comparatively complicated, and hinge-point is many, easily produces " snakelike " (or claiming to walk " S " shape) phenomenon during walking, and its oil cylinder one end is fixed on the pontic, and the other end is fixed on the chassis frame, make steeraxle installation and adjust all cumbersome.Horizontal two-way cylinder steeraxle then directly connects firmly oil cylinder on pontic, make steeraxle install and adjust greatly easy on the chassis, pontic and Tiebar structure are also simplified, and cost descends, and reduced hinge-point than chevron shaped steeraxle, alleviated " snakelike " phenomenon.But its defective be tyre revolution to the time, the oil cylinder piston bar will bear the diametral load that is passed over by pull bar, this will make cylinder sleeve and seal wears very fast, thereby cause hydraulic oil seepage and loss of pressure.
The purpose of this utility model is at above deficiency, and a kind of horizontal two-way cylinder is provided, and the hydro-steering bridge of the guide runner device with float function is installed in its piston rod end.This slide block device can adapt to the change of rotating the time space force direction when ball end automatically, feasible diametral load with respect to oil cylinder mainly acts on the guide rail, thereby alleviated the diametral load that piston rod bore, the wearing and tearing of cylinder sleeve and seal ring are significantly reduced, and all taked the double-layer seal measure at every end of two-way cylinder cylinder barrel, eliminated hydraulic oil seepage and loss of pressure so basically.
Now in conjunction with the accompanying drawings, the utility model is described in detail.
Feature of the present utility model is: relocatable guide runner device ［ 1 ］ is equipped with in piston rod ［ 10 ］ end that connects firmly the two-way cylinder ［ 2 ］ on pontic ［ 9 ］, and slide block ［ 1 ］ is connected with pull bar ［ 5 ］ and steering swivel ［ 8 ］ by ball end ［ 4 ］ again.Guide runner ［ 1 ］ is the convex block of being made by high-abrasive material that has groove, use with strip guide rail ［ 3 ］ pairing with Baltimore groove, adopt the fixing back-up ring ［ 6 ］ of bearing pin to be embedded in the groove of guide runner ［ 1 ］, piston rod ［ 10 ］ then passes E, F two holes on the slide block ［ 1 ］ and is embedded in the mesopore of the back-up ring ［ 6 ］ in slide block ［ 1 ］ groove, and back-up ring ［ 6 ］ directly connects with oil cylinder piston bar ［ 10 ］ by bearing pin ［ 7 ］.There is the space between the roofbolt surface of the E of guide runner ［ 1 ］, F two holes and piston rod ［ 10 ］, can fills certain padded coaming in this space.Ball end ［ 4 ］ is connected with the G hole (taper hole) of an end of guide runner ［ 1 ］.Every end at the two-way cylinder cylinder barrel has all been taked the double-layer seal measure, and double-layer seal mainly is made up of carrier ring ［ 11 ］, this special envelope ［ 12 ］, seal ring ［ 13 ］, O type circle ［ 14 ］.

Fig. 5 is a hydro-steering bridge partial enlarged drawing
The utility model is achieved in that
When two-way cylinder ［ 2 ］ drives package unit ［ 1 ］, ［ 4 ］, ［ 5 ］, the deflection of ［ 8 ］ promotion wheel, passing the road surface counter-force of coming by wheel by steering swivel ［ 8 ］, pull bar ［ 5 ］ and ball end ［ 4 ］ acts on and is decomposed into along the radial and axial two kinds of component of piston rod ［ 10 ］ when slide block ［ 1 ］ is gone up, axial force is acted on the piston rod by back-up ring ［ 6 ］ simultaneously by slide block ［ 1 ］, diametral load is then because there are the space in circular hole E, the F of slide block ［ 1 ］ and the cylinder of piston rod ［ 10 ］, do not act on the piston rod but acts on the guide rail ［ 3 ］.Insert gum filler or oily paste in the space to reduce noise and to make slide block movement steady, when slide block and way rub, this space can also the automatic compensation abrasion loss to guarantee contacting of slide block ［ 1 ］ and guide rail ［ 3 ］.Slide block ［ 1 ］ can adopt cast iron, polytetrafluoroethylene or wear resistant nylon to make.
The utlity model has that simple in structure, install and adjust is convenient, the oil cylinder working-pressure loss is little, the characteristics of long service life.
