Description
Technical field：
The present invention relates to motor vehicle assembly field, a kind of hydraulic booster chassis vehicle axle steering system is related generally to.
Background technology：
Traditional chassis vehicle axle steering system, is made up of some parallel bars, and the tie rod linkage equivalent to four-bar mechanism is realized
, it has the advantages that dependable performance, working stability, simple in construction, easy manufacture, symmetrical attractive in appearance, stress equalization, but it is being turned to
In can have turning error, it is impossible to reach accurate error；The long-time of steering mechanism is used simultaneously, and its bar linkage structure part can go out
Existing micro-strain or loosening it is present, can all influence turning error, what is such as more renewed can also have error, and cause resource
Waste；In order to further reduce error, control is conveniently steered, wheel can be increased, when running into tire increasing demand, such as：
Tire size is increased to 18 inches by 17 inches, and tire envelope can produce the various problems such as interference with front steering section neck and need
Improve.
The content of the invention：
The object of the invention is exactly that there is provided a kind of hydraulic booster chassis vehicle axle steering system in order to make up the defect of prior art.
The present invention is achieved by the following technical solutions：
A kind of hydraulic booster chassis vehicle axle steering system, includes left and right knuckle, brake on chassis, described
Brake is used to brake the wheel hub, is connected on the fulcrum that the left and right knuckle is connected with chassis trapezoidal
It is also associated with connecting by cross bar assembly between knuckle arm, the tie rod arm on arm, and the fulcrum of the connection of left steering section, and
The middle part of cross bar assembly is provided with roller, and chassis corresponding to the roller is provided with arc chute, the knuckle arm it is another
End is connected with steering drag link, and the steering drag link is connected on brake by pitman arm, the tie rod arm and steering
Drag link is the structure that middle part disconnects, and is separately installed with micro-adjusting mechanism in gap.
The radian of described knuckle is steady, and its middle part is horizontal segment.
The cross bar assembly, which includes, is provided with slideway in sleeve pipe, described sleeve pipe, and its one end is sliding combined with slide bar, another
End is welded with connecting rod, and the middle part of described sleeve pipe is provided with roller.
The micro-adjusting mechanism includes fine-tuning nut, and the two ends of the fine-tuning nut are respectively equipped with the opposite spiral shell of hand of spiral
Line, and screw respectively on tie rod arm and steering drag link, graduation mark is distributed with the tie rod arm and steering drag link.
Its operation principle is：Described brake is, in order to transmit motion, and the steering force of input to be amplified, simultaneously
Reduction of speed increment is carried out, the length of described cross bar assembly is variable, and one is constituted between chute, cross bar assembly and upper swing arm
Symmetrical Ackermann steering gear structure, passes through the structure design of chute, it is ensured that wheel does PURE ROLLING during deflection, and
And there is dependable performance, simple in construction, symmetrical attractive in appearance, uniform force, do not have error.When steering mechanism uses for a long time
Afterwards, the fine setting screw thread by tie rod arm and steering drag link is adjusted, reduces and changes number of times, it is ensured that turn to precision.For
Further reduction error, when wheel is increased, by the modification of the local shape to knuckle, is ensureing to install hard spot constant
In the case of, the radian of knuckle is increased, so as to meet the requirement of big wheel.
It is an advantage of the invention that：
The present invention has the advantages that dependable performance, simple in construction, symmetrical attractive in appearance, uniform force, does not have error, and passes through this Shen
Micro-adjusting mechanism please, it is possible to reduce change number of times, it is ensured that turn to precision；When wheel is increased, it is necessary to which part changes knuckle
Shape, in the case where ensureing that installation hard spot is constant, increases the radian of knuckle, so as to meet the requirement of big wheel.
