Abstract
The utility model relates to an automobile power-assisted steering structure. A power-assisted steering oil cylinder fixed to a front steering axle is additionally arranged on an original steering system. Steering knuckle arms are arranged on the both sides of the front steering axle, the steering knuckle arm on one side is connected with a steering straight pulling rod, the steering knuckle arm on the other side is connected with the output end of the power-assisted steering oil cylinder, and a steering gear is connected with the power-assisted steering oil cylinder through an oil path. The automobile power-assisted steering structure is simple in structure, convenient to install, and capable of effectively solving the problem of hard steering of a heavy-duty car with heavy load, a driver has the better driving comfort, and driving safety is improved at the same time.
Description
Technical field
The utility model belongs to wheel steering system technical field, and concrete is a kind of automobile assisted power steering structure.
Background technology
In use, under case of heavy load, steering swivel system can have a strong impact on vehicular drive traveling comfort and driving safety to heavy motor vehicle, and reasonably steering swivel system is most important.Conventional steering system comprises steering pump, moving turns oil tank, bearing circle, deflector, steering drop arm, steering drag link, front steering axle, turns to pipeline etc.Deflector is fixed on frame outside, and deflector top is connected with bearing circle by spline housing; Steering drop arm upper end is connected with deflector, and lower end is connected with steering drag link; Steering drag link is connected with the track arm of front steering axle.Move and turn oil tank to steering pump fuel feeding; Steering pump is to deflector fuel feeding; Turn oil tank oil return by deflector return opening to moving.The left/right rotation power of bearing circle is finally delivered to the track arm of front steering axle, and track arm motion drives front steering axle, controls vehicle wheel rotation.Heavy motor vehicle turns to because the friction force of wheel increases in the time of heavy duty at present, makes hard steering, has a strong impact on traveling comfort and the driving safety of driving.
Utility model content
The utility model, for the deficiency in background technology, proposes a kind of flexible, light automobile assisted power steering structure that turns in the time of heavy duty, thereby improves traveling comfort and the driving safety driven.
The technical solution adopted in the utility model is: automobile assisted power steering structure, comprises deflector, steering drop arm, steering drag link, front steering axle, moving oil tank, the steering pump of turning; Deflector is fixed on frame outside; Steering drop arm upper end is connected with deflector, and lower end is connected with steering drag link; Steering drag link is connected with front steering axle; Moving turn oil tank and be connected with steering pump by oil circuit; Steering pump is connected with deflector by oil circuit; Deflector turns oil tank oil return by oil circuit to moving; It is characterized in that: also comprise the servo-steering oil cylinder being fixed on front steering axle; Described front steering axle is provided with the first track arm with side, and opposite side is provided with the second track arm; Described the first track arm is connected with steering drag link; Described the second track arm is connected with the mouth of described servo-steering oil cylinder; Deflector is connected with described servo-steering oil cylinder by oil circuit.
Preferably, described servo-steering oil cylinder is fixed on the through beam of described front steering axle.
Further preferred, described through beam middle part is provided with horizontal mounting bracket, and described servo-steering oil cylinder is fixed on described horizontal mounting bracket.
The beneficial effects of the utility model are: simple in structure, easy for installation, and can effectively solve the problem of the hard steering of heavy motor vehicle in the time of heavy duty, and make steerman have better driver comfort, also improve driving safety simultaneously.

The specific embodiment
As depicted in figs. 1 and 2, automobile assisted power steering structure, comprises deflector 1, steering drop arm 3, steering drag link 4, front steering axle 5, moving oil tank 6, steering pump 7, the servo-steering oil cylinder 8 of turning; Deflector 1 is fixed on vehicle frame 2 outsides; Steering drop arm 3 upper ends are connected with deflector 1, and lower end is connected with steering drag link 4; Steering drag link 4 is connected with front steering axle 5; Moving turn oil tank 6 and be connected with steering pump 7 by steering pump oil inlet 7.1; Steering pump 7 is connected with deflector 1 by deflector oil inlet 1.1; Deflector 1 turns oil tank 6 oil returns by oil return pipe 6.1 to moving; The fixed end of described servo-steering oil cylinder 8 is fixed on the horizontal mounting bracket 5.31 at described front steering axle 5 through beam 5.3 middle parts; Described front steering axle 5 one sides are provided with the first track arm 5.1, and opposite side is provided with the second track arm 5.2, the first track arms 5.1 and is connected with steering drag link 4; The second track arm 5.2 is connected with the mouth of described servo-steering oil cylinder 8; Deflector 1 is connected with described servo-steering oil cylinder 8 by servo-steering oil path in oil cylinder 8.1.
On original steering swivel system basis, increase servo-steering oil cylinder, front steering axle right side increases by the second track arm, servo-steering oil cylinder fixed end is also that afterbody is fixed on the horizontal mounting bracket on front steering axle through beam, and the mouth of servo-steering oil cylinder is connected with the right steering of front steering axle joint arm; Move and turn oil tank to steering pump fuel feeding; Steering pump is to deflector fuel feeding, and steering box turns oil tank oil return to moving, thereby turned oil tank, steering pump and deflector and formed a large loop by moving; Between deflector and servo-steering oil cylinder, form a little loop.Meanwhile, directly rush that deflector is drawn and servo-steering oil cylinder between loop, reduced the setting of oil circuit.Steering effort while making like this bearing circle left-right rotation is finally delivered to the left steering joint arm of front steering axle by deflector, steering drop arm, steering drag link, the motion of left steering joint arm drives front steering axle, controls vehicle wheel rotation; The flexible right steering joint arm motion auxiliary wheel that drives of servo-steering oil cylinder turns to simultaneously.Thereby there is better driver comfort, also improved driving safety simultaneously.
