Abstract
The invention discloses a device for connecting a transverse steering oil cylinder piston rod with a connecting rod. The steering oil cylinder piston rod can be assembled in a cylinder barrel by rotating by 90 degrees. On a steering axle body, a rotatable two-position connecting steering oil cylinder piston rod, a double-sheet I-shaped connecting rod and a steering knuckle arm are sequentially connected through hinge pins. The head part of the rotatable two-position connecting steering oil cylinder piston rod is provided with two vertically intersecting hinge holes, and the piston rod can be assembled in another hinge hole by rotating along an axle center by 90 degrees, so that a positive pressure acts on a new position on the rotatable two-position connecting steering oil cylinder piston rod during working, excessive friction, wear and scrap of a fixing position are avoided, and the service life of the device is prolonged. The double-sheet I-shaped connecting rod has a symmetrical structure, can be alternatively assembled on a left side and a right side, and is convenient to manufacture.
Description
Affiliated technical field
The present invention relates to the device that a kind of transverse steering oil cylinder piston rod connects with connecting rod, the steering oil cylinder piston rod can be adjusted back in cylinder barrel and turn 90 degrees and the connecting rod attaching.
Background technique
At present, transverse steering equipment connects the steering oil cylinder piston rod by connecting rod with knuckle, and hydraulic oil promotes piston rod move left and right in cylinder barrel, realizes turning to by connecting rod push-and-pull knuckle.And under the effect of ground reaction force, deflecting roller reacts on reaction force on connecting rod and the oil cylinder piston bar by steering knuckle arm, piston rod has produced positive pressure to guide sleeve, when piston rod moves, positive pressure has produced frictional force, makes on the surface of contact of piston rod and guide sleeve and has produced fretting wear.Again owing to connect the restriction of pattern, the steering oil cylinder piston rod can not turn round, just long-time the concentrating of frictional force acts on single position, the contacted friction of piston rod and guide sleeve position immobilizes, make other position to utilize, cause the wearing and tearing of rubbing surface to be accelerated, shorten the working life of piston rod.
Summary of the invention
In order to overcome the deficiency that the single position of existing transverse steering oil cylinder piston rod is subjected to fretting wear, the invention provides a kind of coupling arrangement, this device can return piston rod as required and turn 90 degrees and the connecting rod attaching in cylinder barrel.Before excessive wear does not take place in former rubbing surface, piston rod is turned over 90 degree, make friction-produced between piston rod and guide sleeve on another new rubbing surface.Like this, piston rod and guide sleeve working surface are fully used, thereby increase the service life.
The technical solution adopted for the present invention to solve the technical problems is: steering oil cylinder piston rod two design is had two hinging holes of corresponding square crossing, and a hinging hole connects with connecting rod during work, and another is standby.Reach the regular hour when a hinging hole connects with connecting rod to use, before the former rubbing surface of piston rod does not produce excessive wear, the steering oil cylinder piston rod returned in cylinder barrel to turn 90 degrees, to allow another hinging hole connect use with connecting rod.Because the steering oil cylinder piston rod returns and turn 90 degrees, and another position of piston rod is contacted with guide sleeve, the friction position is changed, and makes full use of the purpose that the piston rod working surface increases the service life thereby reach.
The invention has the beneficial effects as follows that the working surface of transverse steering oil cylinder piston rod is fully used, and prolongs its working life.

Embodiment
In embodiment illustrated in fig. 1, knuckle seat (4), knuckle (5) and cylinder barrel (10) are installed on and turn to pontic (1), and steering knuckle arm (6), the board-like connecting rod of monolithic (7) and fixing unidirectional jointing type steering oil cylinder piston rod (8) connect with swivel pin (3).When turning to, fixing unidirectional jointing type steering oil cylinder piston rod (8) move left and right of hydraulic oil promotion from tubing interface (2) realizes turning to by the board-like connecting rod of monolithic (7) push-and-pull steering knuckle arm (6).
Shown in Figure 3 is among first embodiment, and fixing unidirectional jointing type steering oil cylinder piston rod (8) is subjected to position A, the B of positive pressure when working, and during the piston rod move left and right, the position that is subjected to positive pressure produces friction and wear.
In embodiment illustrated in fig. 4, steering knuckle arm (6), biplate plate worker type connecting rod (11) and can turn round dibit jointing type steering oil cylinder piston rod (12) and connect with swivel pin (3).When turning to, can turn round dibit jointing type steering oil cylinder piston rod (12) move left and right, realize turning to by biplate plate worker type connecting rod (11) push-and-pull steering knuckle arm (6) from the hydraulic oil promotion of tubing interface (2).
Shown in Figure 5 is among second embodiment, in the time of need turning transposition, pull down swivel pin (3) and biplate plate worker type connecting rod (11), return along the axle center and turn 90 degrees turning round dibit jointing type steering oil cylinder piston rod (12), another eyelet of square crossing hinging hole (13) is gone in the transposition attaching, swivel pin (3) is the good biplate plate of attaching worker type connecting rod (11) again, makes positive pressure in turning round the new position of dibit jointing type steering oil cylinder piston rod (12).
Shown in Figure 6 is among second embodiment, can turn round the sectional view of dibit jointing type steering oil cylinder piston rod (12) head, and one of them eyelet of square crossing hinging hole (13) is to dress swivel pin (3) during work, and another eyelet is standby.
Shown in Figure 7 is among second embodiment, two views of biplate plate worker type connecting rod (11).
