Abstract
The invention discloses a steering system which comprises a frame and wheels arranged at the lower end of the frame. The frame is provided with a steering wheel turning angle input device, and the steering wheel turning angle input device is provided with a circulating ball mechanism; the circulating ball mechanism is provided with a main hydraulic control cylinder; the main hydraulic control cylinder is arranged at the wheel arranging end of the frame and provided with a steering rocker arm; the steering rocker arm is arranged between the wheels. In this way, the steering system has the advantages that the structure is simple, and the steering torque of the wheels is increased; more labor is saved, and the phenomenon that teeth are prone to be damaged due to the fact that the steering input force brought by a gear mechanism is large can be effectively avoided.
Description
Technical field
The present invention relates to the improvement of a kind of steering, particularly to a kind of simple in construction, increase high-wheeled steering moment；More laborsaving, the steering turning to the problems such as the input big perishable tooth of power that gear mechanism is brought can be prevented effectively from.
Background technology
Mountain carrier vehicle is applicable to the mountain region road conditions of complexity, thus the most harsh to turning to requirement, when i.e. turning to upper high slope to travel, turns to machine to be still provided that enough moment.Frame for movement in the process, does not haves the power excessively concentrated and makes component damage.Traditional dilly many employings gear & rack structure, Some vehicles, for reducing steering wheel opplied moment, sets up assistant steering device, such as power-assisted steering pump, steer motor etc..And these structures arrange that the steering linkage being required for meeting both sides wheel is connected, for the hill path risen and fallen, the concavo-convex stone ramp towered, this structure is obviously by being extremely difficult to requirement in property.
For meet automobile by property requirement, the layout orientation of track rod simultaneous is got rid of, and travelling gear tooth bar structure easily occurs that stress is excessive, causes broken teeth phenomenon, therefore the most not directly uses.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of simple in construction, increases high-wheeled steering moment；More laborsaving, the steering turning to the problems such as the input big perishable tooth of power that gear mechanism is brought can be prevented effectively from.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of steering, including: vehicle frame and the wheel being arranged on vehicle frame lower end；Described vehicle frame is provided with steering wheel angle input equipment；Described steering wheel angle input equipment is provided with circulating ball mechanism；Described circulating ball mechanism is provided with hydraulic control master cylinder；Described hydraulic control master cylinder is arranged on the wheel set terminal of vehicle frame；Described hydraulic control master cylinder is provided with pitman arm；Described pitman arm is arranged between the wheels.
Preferably, described hydraulic control master cylinder is two-way hydraulic cylinder, comprising: port cylinder and turn to right cylinder.
The invention has the beneficial effects as follows: a kind of steering of the present invention, simple in construction, take pure the surging of non-rigid connection to turn to, increase high-wheeled steering moment；Further, in terms of the input of power, circulating ball has labour-saving advantage compared to gear, and can be prevented effectively from that gear mechanism brought turns to the problems such as the input big perishable tooth of power.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the structure principle chart of a kind of steering of the present invention；
Wherein: 1, steering wheel angle input equipment；2, circulating ball mechanism；3, hydraulic control master cylinder；4, port cylinder；5, right cylinder is turned to.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to Fig. 1, the embodiment of the present invention includes:
For solving above-mentioned technical problem, the technical scheme that the present invention uses is a kind of steering, including: vehicle frame and the wheel being arranged on vehicle frame lower end；Described vehicle frame is provided with steering wheel angle input equipment 1；Described steering wheel angle input equipment 1 is provided with circulating ball mechanism 2；Described circulating ball mechanism 2 is provided with hydraulic control master cylinder 3；Described hydraulic control master cylinder 3 is two-way hydraulic cylinder, comprising: port cylinder 4 and turn to right cylinder 5；Described hydraulic control master cylinder 3 is arranged on the wheel set terminal of vehicle frame；Described hydraulic control master cylinder 3 is provided with pitman arm；Described pitman arm is arranged between the wheels；During work, steering wheel angle input equipment 1 inputs corner, using hydraulic control master cylinder 3 as driving element, is acted on by the pitman arm being arranged between two-wheeled and hydraulic control master cylinder 3 simultaneously, make car load turn to.
The invention has the beneficial effects as follows: a kind of steering of the present invention, simple in construction, take pure the surging of non-rigid connection to turn to, increase high-wheeled steering moment；Further, in terms of the input of power, circulating ball has labour-saving advantage compared to gear, and can be prevented effectively from that gear mechanism brought turns to the problems such as the input big perishable tooth of power.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
