Abstract
The invention provides a servo steering mechanism of a back shaft of a trailer. The servo mechanism comprises the back shaft and two back wheels, wherein the two back wheels are respectively provided with steering arms; extending arms are respectively arranged at two ends of the back shaft; the steering arms are moveably connected with the extending arms through steering shafts; the steering arms can rotate around the steering shafts; a steering pull rod is arranged between the two back wheels; two ends of the steering pull rod are respectively connected with the two steering arms; and when a vehicle turns, the trailer is dragged by a tractor, the trailer is stressed by a steering force, the steering arms of the back wheels rotate around the steering shafts, and the back wheels maintains synchronous steering through the steering pull rod. Thus, after the servo steering mechanism is used, when the vehicle turns, the friction between tires and the ground is reduced, the service lives of the tires are prolonged, and simultaneously, the consumption of fuel can be saved.
Description
Technical field
The present invention relates to the trailer technical field, refer in particular to a kind of follow-up steering mechanism of trailer rear axle.
Background technology
At present, trailer mainly comprise the traction headstock and with traction headstock bonded assembly trailer, traditional trailer axletree adopts the axle tree suspension, this system is not provided with self-steering gear.Because the back sedan-chair of trailer does not have steering hardware, Ackermann steer angle, the tire of back sedan-chair can produce bigger friction with ground, and the Occupation coefficient of tire is increased, the life-span of having reduced tire, also increased the consumption of fuel oil simultaneously, cause unnecessary waste.
Summary of the invention
The objective of the invention is to provide a kind of follow-up steering mechanism of trailer rear axle at the deficiencies in the prior art.
For achieving the above object, the present invention is achieved by the following technical solutions.
A kind of follow-up steering mechanism of trailer rear axle, comprise rear axle and two rear wheels, two rear wheels are respectively arranged with spindle arm, the two ends of described rear axle are respectively arranged with extension arm, described spindle arm flexibly connects by steering shaft and described extension arm, described spindle arm can rotate around described steering shaft, is provided with steering track rod between two rear wheels, and the two ends of steering track rod are connected with two spindle arms respectively.
Further comprise damper, described damper comprises damping tube and piston rod, and described damping tube is fixed in described rear axle, and the piston rod of described damper is connected with described steering track rod.
Described damper is arranged at the middle part of described steering track rod, and the piston rod of described damper is connected with described steering track rod by bolt.
Further comprise the reversing blocking device, described reversing blocking device comprises lock body and locking bar, and when the reversing blocking device was activated, described locking bar inserted and stops piston rod flexible in the described damper.
Beneficial effect of the present invention is: rear wheel of the present invention is provided with spindle arm, spindle arm flexibly connects by the extension arm of steering shaft and rear axle, the spindle arm of two rear wheels connects by steering track rod, the Ackermann steer angle trailer is subjected to pulling of tractor truck, trailer is subjected to the effect of steering effort, the spindle arm of rear wheel rotates around steering shaft, rear wheel keeps turning to synchronously by steering track rod, therefore, after adopting the present invention, Ackermann steer angle, tire and ground-surface friction reduce, prolong the service life of tire, the consumption that also can save fuel oil simultaneously.

In Fig. 1, include:
1---Rear axle
2---the wheel body
3---spindle arm
4---extension arm
5---steering shaft
6---steering track rod
7---damper
71---the damping tube
72---piston rod

The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
See Fig. 1, a kind of follow-up steering mechanism of trailer rear axle, comprise rear axle 1 and two rear wheels 2, two rear wheels 2 are respectively arranged with spindle arm 3, the two ends of rear axle 1 are respectively arranged with extension arm 4, and spindle arm 3 flexibly connects by steering shaft 5 and extension arm 4, and spindle arm 3 can rotate around steering shaft 5, be provided with steering track rod 6 between two rear wheels 2, the two ends of steering track rod 6 are connected with two spindle arms 3 respectively.
Further comprise damper 7, damper 7 comprises damping tube 71 and piston rod 72, and damping tube 71 is fixed in rear axle 1, and the piston rod 72 of damper 7 is connected with steering track rod 6.
Preferably, damper 7 is arranged at the middle part of steering track rod 6, and the piston rod 72 of damper 7 is connected with steering track rod 6 by bolt.The turning velocity of damper 7 may command two rear wheels 2 makes that the turning velocity of two rear wheels 2 can be not too fast, increases traveling security.In addition, the piston rod 72 of damper 7 is provided with range, and when piston rod 72 reached range, steering track rod 6 promptly entered " dead angle ", and therefore, the hard-over of two rear wheels 2 is subjected to the restriction of damper 7, and steering locking angle degree of the present invention is 20 degree.
Further comprise reversing blocking device 8, reversing blocking device 8 comprises lock body 81 and locking bar 82, and when reversing blocking device 8 was activated, locking bar 82 inserted and stops piston rod 72 flexible in the damper 7, promptly limits two rear wheels 2 and turns to.Because trailer forbids that two rear wheels 2 turn to when reversing, otherwise can make trailer be difficult to control.The purpose that the present invention increases reversing blocking device 8 is, when trailer in when reversing, by reversing blocking device 8 locking dampers 7, and then locking steering track rod 6, stop two rear wheels 2 to turn to.
Certainly, the embodiment of the above is a preferred embodiments of the present invention, and unrestricted the scope of the present invention, so all equivalences of doing according to the described structure of the present patent application claim, feature and principle change or modify, and all should be included in the present patent application claim.
