Technical field
Intersect a few font steering mechanism and card the invention belongs to vehicle steering structure technical field, more particularly to a kind of front ladder
Fourth car.
Background technology
For changing or keeping a series of devices of vehicle traveling or reverse direction to be referred to as wheel steering system (steering
System), its function is exactly the travel direction that vehicle is controlled according to the wish of driver.Vehicle in the process of moving, need to be by driving
The will for the person of sailing often changes its travel direction, i.e., so-called Vehicular turn.For wheeled vehicle, the method for realizing Vehicular turn
It is that driver makes the wheel (deflecting roller) on vehicle steer axle (being usually propons) relative to car by a set of ad hoc mechanism
Longitudinal axis deflection certain angle.When its straight line is travelled, deflecting roller also tends to be acted on by the lateral perturbed force in road surface,
And change travel direction is deflected automatically.Now, driver just can be such that deflecting roller deflects round about using this set mechanism, from
And vehicle is returned to original travel direction.
Mechanical steering system is using the muscle power of driver as steering power source, wherein all force transmission elements are all mechanical, by
Steering control mechanism, steering gear and steering gear three parts composition, mainly including steering wheel, steering drive axle, steering
Universal joint, steering gear, pitman arm, steering linkage, knuckle etc..During Vehicular turn, driver turn steering wheel, by turning to
Power transmission shaft, steering universal joint are by steering moment input steering gear, then pass to pitman arm, be transmitted to by steering linkage be fixed on turn
To the knuckle arm on section, make knuckle and loaded on steered wheel deflection thereon, while making the angle that left and right turn wheel is deflected
Degree presses certain relationship change, to ensure that the relative slip on wheel and ground during Vehicular turn is as small as possible.
Steering trapezium is the critically important part of vehicle steering system, influences the maneuvering performance of vehicle, can also influence tire
Abrasion.Correct design tie rod linkage, it is ensured that Ackermann steer angle, whole wheels rotate around instantaneous center of turn.Turn
To the composition of mechanism with arrangement because steering gear position, suspension type are different and different.Current steering mechanism, it is in order to ensure lubrication groove
Angular difference, complicated, manufacturing cost is high.
