Description
Technical field
The invention belongs to automobile front steering technical field, particularly relate to it is a kind of turn to vice president into and its automobile.
Background technology
The front steering axle of commercial car is the non-disconnected driven bridge of steering, and front steering axle structure is very complicated, as shown in figure 1, being
Prior art front steering axle and related components, including wheel hub 01, knuckle 02, upper bushing 03, adjust pad 04, wedge-shaped lock pin
05th, stub 06, steering trapezoidal arm 07, knuckle arm 08, front axle 09, leaf spring 010, track rod 011, ball pin 012, lower bushing
013rd, thrust bearing 014, inner bearing 015 and outer bearing 016.Stub is fixed on front axle fist portion by the wedge-shaped lock pin with bolt
In kingpin bore, it is allowed to rotate, knuckle is hinged composition using stub and front axle and turns to pair, and through inner bearing and outer bearing branch
The wheel hub of wheel is supportted, to reach the purpose of wheel steering.Knuckle arm is installed at the upper ear of left steering section, the latter is with turning
It is connected to Drag link, driving turns to secondary progress divertical motion；And be then equipped with and track rod at the lower ear of left and right knuckle
The steering trapezoidal arm of connection, the steering trapezium being made up of during steering steering trapezoidal arm, ball pin and track rod etc. realizes vehicle
Each tire fricton-tightly roll steering.Press-in carries the bronze bushing of lubricating grease to reduce mill in the kingpin bore of knuckle
Damage.To make steering light, roller thrust bearing, ear and front axle on knuckle are housed under knuckle between ear and front axle fist portion
Pad is housed between fist portion to adjust its gap.
The divertical motion of wheel is by turning to secondary completion, turning to pair and is mainly made up of knuckle, front axle and stub etc., born
Wheel hub, bearing, the active force of knuckle and impact are passed to by wheel.Turn to the divertical motion frictional force and king pin axis of pair
Space angle directly affect the steering behaviour, portability and control stability of vehicle.
Front-wheel returnability after stability, ease of steering and motor turning in order to keep automobile straight-line travelling, before steering
The stub of bridge has certain inclination angle in the vertical and horizontal plane of automobile.In fore-and-aft plane, stub top rear-inclined one
γ angles, referred to as castor.One β angle of stub top inward slant, kingpin inclination in transverse plane.
Reverse caster makes main pin axis and the intersection point on road surface be located at before tire earth point, and 2 points of distance is referred to as always dragging
Square, this total offset distance includes the vertical offset distance of stub and tire drags square, when the deflecting roller of the automobile of straight-line travelling is slightly deflected, at this moment
Caused centrifugal force makes road surface apply the lateral deviation power for hindering its deflection to wheel, wheel is produced around what stub rotated and returns positive force
Square, so as to ensure that automobile has preferable straight motion stability, this aligning torque is equal to total offset distance and the product of lateral deviation power.Though
Can so change castor by changing stub opposite plate spring bracket seat longitudinal angle, but for the ease of front axle plus
Work, this angle is essentially 0, therefore, and castor depends primarily on the Installation posture of leaf spring, or between leaf spring and front axle
Plus correcting wedge, front steering axle castor is generally 1~3 °.
Kingpin inclination also makes to ensure the stability and ease of steering of automobile straight-line travelling.Kingpin inclination makes main pin
Line and the intersection point on road surface to the distance in tire centerline face are that offset distance reduces in stub, so as to reduce steering during rotation steering wheel
Power, makes steering light, while can also reduce the impulsive force that deflecting roller is delivered on steering wheel.The kingpin inclination 5 of front steering axle
~8 °, now with the trend of increasing.
In the process of moving, when reaching a certain speed, steering system integrally vibrates vehicle, and steering wheel also vibrates therewith,
This phenomenon is called shimmy of front wheels, and shimmy of front wheels is the oscillation phenomenon that front steering axle must be noted that.
In order to improve running car straight trip property, the aligning torque of deflecting roller must be just improved, at the same time it is also necessary to reduce steering
Power, improves ease of steering.But for turning particularly to propons, different structures is used for offset distance in different stubs, with
Ensure while performance is improved, do not occur shimmy of front wheels.
Therefore, there is the vertical offset distance of different stubs in the arrangement for different front steering axles, and different stubs are indulged offset distance and used
Different steering pairs.
As shown in Fig. 2 be the steering pair of prior art, including knuckle 02, stub 06, upper bushing 03, wedge-shaped lock pin 05,
Front axle 09, lower bushing 013 and thrust bearing 014, using copper bush, kingpin inclination is than larger.
Upper bushing and lower bushing are all copper bush, and force of sliding friction reduces than larger when knuckle is with stub relative motion
Automobile aligning torque；Offset distance is big in stub, and rotating torque is just big, rotates portability poor；Offset distance is big in stub, what deflecting roller was subject to
Impact is just big, and stability is very poor during straight-line travelling；Copper bush abrasion is very fast.
The content of the invention
It is an object of the invention to provide one kind turn to vice president into and its automobile, turn to secondary liner structure by improving, subtract
Aligning torque when frictional force during small steering pair rotation improves vehicle traveling, what the straight trip and vehicle that raising vehicle is travelled were travelled
Stability.

Operation principle
Needle roller is cylinder, and side is tangent with stub, and the inner cylinder face of opposite side and upper shell or lower house is tangent, is formed
Rolling movement of the stub in needle roller bushing, force of rolling friction very little.And between upper bushing and stub it is sliding friction, frictional force
It is larger.
If all using sliding friction up and down, frictional force is larger, is unfavorable for steering reversal, steering force is also than larger；
If all using rolling friction up and down, frictional force very little is conducive to steering reversal, steering force also very little.Due in stub
Offset distance is in 20 ± 10mm, and vehicle travels the interference by road surface still than larger, easily produces shimmy of front wheels in a certain speed,
So using the scheme of upper sliding friction, lower rolling friction, taking into account steering behaviour and reducing and vibrate.
End screwed hole on stub is additionally operable to store lubricating oil, and is slided with stub circular hole, straight oil groove, X-shaped oil groove and curved neck formula
Oil nozzle is communicated, and when the lubricating oil of upper bushing reduces, storage lubricating oil can flow back, and reduce the maintenance cycle of upper bushing.
Front steering axle have left and right two turn to vice president into, due to left steering vice president into right turn vice president into relative vehicle
Median plane is symmetrical, so, the technical program is only to left steering vice president into illustrating.
The technical program also provides a kind of automobile, the front steering axle of the automobile using above-mentioned left steering vice president into and turn right
To vice president into.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And deformation, the scope of the present invention extremely equally limits by appended claims.
