Abstract
The invention belongs to the technical field of vehicle engineering and particularly relates to a vehicle steering mechanism. According to the technical scheme, a rear-axle steering vehicle comprises a frame, a front axle, front wheels, a rear axle, rear wheels, a steering mechanism, a rotating support and a folding arm. The rotation of the whole rear axle with respect to the frame is achieved by connecting the rear axle and the frame through the rotating support. Real-time steering of the rear wheels in the rotating process of the rear axle by arranging the folding arm mechanism. By the adoption of the technical scheme, the problem that the wheels are limited by space and cannot steer at a large angle. By the adoption of the technical scheme, the problem of large-angle steering of the rear wheels is achieved, and the trafficability is improved.
Description
Technical field
The invention belongs to Vehicle Engineering technical field, more particularly to vehicle steering mechanism.
Background technology
At present, as shown in Figure 1 the rear axle steering vehicle application of structural principle is extensive, especially in commercial car, engineering truck
Field.The rear axle steering vehicle includes：Vehicle frame 3, front axle 1, front-wheel 11, rear axle 2, trailing wheel 21, steering mechanism 4；Steering mechanism 4
Pitman arm 41 and steering link 42 are connected rear axle 2 with front-wheel 11, and pitman arm 41 is connected with vehicle frame revolute, steering link
42 two ends are typed ball bearing pair, and it is connected with pitman arm 41, rear axle 2.Prior art is realized based on ripe automobile accessories technology
The turning function of trailing wheel, but corner value limited by vehicle component space, be not it is very big, the radius of turn of vehicle also just compared with
Greatly, driving through property is restricted.So, vehicle is when sharp turn operating mode or hill path operating mode are travelled, it may appear that tire departs from track,
Even car body touches massif and impassable crag-fast situation, has a strong impact on highway communication and inherently safe.
The content of the invention
The purpose of the present invention is：There is provided one kind can travel with more tight turn radius, and highway communication is smooth and vehicle for guarantee
And the rear axle steering vehicle of personal security.
The technical scheme is that：A kind of rear axle steering vehicle, including：Vehicle frame, front axle, front-wheel, rear axle, trailing wheel turns
To mechanism, pivoting support, folding arm；
Pivoting support includes：The upper body connected by ball and lower body；Pivoting support is arranged on vehicle frame posterior center, lower body
It is fixedly connected with rear axle, upper body is fixedly connected with vehicle frame, makes rear axle to rotate with vehicle frame around pivoting support center；
Vehicle frame both sides respectively arrange a folding arm；Folding arm one end is connected with the side vehicle frame by typed ball bearing pair, the other end and the side
Rear axle is connected by typed ball bearing pair；In rear axle rotation process, folding arm pulls or promotes trailing wheel deflection.
Beneficial effect：Present invention achieves trailing wheel wide-angle is turned to so that wheel steering angle value is limited little by space, and vehicle is exhausted
Corner is increased, vehicle turn radius are little, improve trafficability, it is suitable to answer special driving cycle.

Specific embodiment
Embodiment 1, referring to accompanying drawing 2,3, a kind of rear axle steering vehicle, including：Vehicle frame 3, front axle 1, front-wheel 11, rear axle 2, after
Wheel 21, steering mechanism 4, pivoting support 5, folding arm 6；
Pivoting support 5 includes：The upper body 51 connected by ball and lower body 52；Pivoting support 5 is arranged in the rear portion of vehicle frame 3
The heart, lower body 52 is fixedly connected with rear axle 2, and upper body 51 is fixedly connected with vehicle frame 3, makes the rear axle 2 can be around the center of pivoting support 5 and vehicle frame
3 rotate；
The both sides of vehicle frame 3 respectively arrange a folding arm 6, and the one end of folding arm 6 is connected with the side vehicle frame 3 by typed ball bearing pair, the other end and
The side rear axle 2 is connected by typed ball bearing pair；In the rotation process of rear axle 2, folding arm 6 is pulled or promotes trailing wheel 21 to deflect, and trailing wheel 21 is relative
The corner of vehicle frame 3 is the superposition of the relative corner of rear axle 2 of corner and trailing wheel 21 of the relative frame 3 of rear axle 2, that is, increase the phase of trailing wheel 21
Corner to front-wheel 11, reduces vehicle turn radius.
Its turning process is：Travel to bend, driver's steering wheel rotation, control front-wheel 11 is turned to；There is corner in front-wheel 11,
Rear axle 2 is pulled or promoted by steering mechanism 4 around the center rotating of pivoting support 5；In the rotation process of rear axle 2, folding arm 6 is pulled or pushed away
Dynamic trailing wheel 21 is rotated, and trailing wheel 21 increases the corner of the relative frame 3 of trailing wheel 21, i.e. trailing wheel on the basis of the corner of relative rear axle 2
The corner increase of 21 opposing front wheels 11；Front-wheel 11 determines turning center and the radius of turn of vehicle with trailing wheel 21 jointly, because of trailing wheel
21 corner increase so that radius of turn reduces；Vehicle crosses bend.
Embodiment 2：Present invention could apply to many rear axle vehicles, referring to accompanying drawing 4, such as the rear axle steering vehicle of embodiment 1
On the basis of increase the second rear axle 7 and the second trailing wheel 71, the second rear axle 7 is fixedly connected on lower body 52 jointly with rear axle 2；Thus exist
The both sides of vehicle frame 3 increase the folding arm coordinated with the second rear axle 7, i.e., the folding arm 8 shown in figure；One end of folding arm 8 and the side vehicle frame 3
Connected by typed ball bearing pair, the other end is connected with second rear axle of side 7 by typed ball bearing pair.
