Abstract
The invention discloses a hydraulic double-steering front axle. The hydraulic double-steering front axle comprises a front axle, a steering arm, a ball pin I, a connecting rod, a ball pin II, a hydraulic oil cylinder and a fixed plate. The hydraulic double-steering front axle has the beneficial effects that wheels on the two sides of the front axle are driven to synchronously steer by adopting a hydraulic pump with two-way piston rods at two ends, the structure is compact, the operation is facilitated, the steering is flexible and the safety and reliability are high.
Description
Technical field
The present invention relates to field of automobile, be specifically related to a kind of Hydraulic Double front steering axle.
Background technology
Automobile front axle steering hardware general at present, be driven by drag link to turn to curved boom to rotate, turn to curved boom to drive steering swivel to rotate, steering swivel drives vehicle wheel rotation, then by intermediate rod driving automobile propons two sidecar wheel synchronous axial system.When this steering hardware is handled, bearing circle is heavier, and when, vehicle bridge narrower for vehicle body is shorter, cannot install because turning to the restriction of curved boom and drag link installing space.Thus the Front Axle Steering Mechanism of this technology must be improved.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Hydraulic Double front steering axle equipment special.
The present invention is achieved through the following technical solutions.
A kind of hydraulic steering front axle, comprises pitman arm, 1 ball end, pitman, 2 ball ends, hydraulic ram, adapter plate formation;
A kind of hydraulic steering front axle of the present invention, described hydraulic ram is installed in the middle of the pitman arm at propons two ends, is fixed on front axle by adapter plate; Hydraulic ram both sides are equipped with piston rod, and each activity connection of piston rod head at two ends draws 1 ball end and 2 ball ends of both sides, and 1 ball end connects short rod with in the middle of 2 ball ends, and short rod connects pitman arm by 2 ball ends.Pitman arm is connected with front axle steering knuckle.
As preferred technical scheme, described 1 ball end and 2 ball ends are equipped with being actively coupled of sphere.
As preferred technical scheme, described short rod two ends and 1 ball end connect with 2 ball ends for Bolt Connection.
Beneficial effect of the present invention is:
The hydraulic ram of two-way double piston-rod, has promoted synchronously turning to of propons two sidecar wheel.Compact conformation, easy to operate, turn to flexibly, safe and reliable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A direction view of Fig. 1;
Fig. 3 is the structural representation that ball end connects.
Detailed description of the invention
Consult a kind of bidirectional hydraulic front steering axle shown in Fig. 1 and Fig. 2, comprise propons 1, pitman arm 2,1 ball end 3, short rod 4,1 ball end 5, hydraulic ram 6, adapter plate 7; Described hydraulic ram 6 is arranged on the centre of propons 1 two ends pitman arm 2 by adapter plate 7; The piston rod that described hydraulic ram 6 two ends are stretched out, is actively coupled by 1 ball end 3 and 2 ball end 5, and 1 ball end 3 connects short rod 4 with in the middle of 2 ball ends 5, and short rod 4 connects pitman arm 2 by 2 ball ends 5.Pitman arm 2 connects with propons 1.
Consult described in Fig. 3,1 ball end 3 and 2 ball end 5 is equipped with sphere 3-1 and 5-1.Described short rod 4 two ends and ball end 1 connect with ball end 2 for Bolt Connection 4-1.
Further, a kind of hydraulic steering front axle, it turns to and is controlled by the symmetrically arranged double piston-rod in hydraulic ram two ends, and hydraulic cylinder piston rod connects a short rod by bulb, and short rod connects pitman arm by bulb.After oil cylinder enters a lateral movement of pressure oil piston, drive short rod to promote to the translation of homonymy direction, short rod drives again pitman arm to rotate.In like manner, short rod motion of translation is pulled at the opposite side piston rod of oil cylinder, short scuffing of cylinder bore pulls pitman arm to rotate, because double piston-rod and piston are rigidly connected, so the motion of both sides piston rod is constant speed, it is meet propons steering trapezium rule that both sides pitman arm and propons turn to, and it is synchronous for turning to.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
