Abstract
Provided is a four-wheel steering device. According to the four-wheel steering device, a front left wheel, a front left steering arm, a front left steering shaft, a front pull rod, a front right steering arm, a front right wheel, a front right steering shaft, a drive rod, a rotary crank arm, a spring, an eccentric shaft, a driven rod, a rear right steering shaft, a rear right wheel, a rear right steering arm, a rear pull rod, a rear left steering shaft, a rear left steering arm and a rear right wheel are connected in sequence. Four steering shafts are fixed still. Each of four steering arms is capable of rotating around a corresponding steering shaft. The drive rod is provided with a groove portion and is capable of sliding in the driven rod. When two front wheels veer, a defect surface of the eccentric shaft approaches the drive rod, the drive rod is capable of freely sliding in the driven rod, front wheel steering is incapable of driving the driven rod to move, and rear wheels do not veer along with the front wheels. Otherwise, the defect surface of the eccentric shaft departs from the drive rod, the drive rod and the driven rod are connected into a whole through the eccentric shaft, the front wheel steering drives the driven rod to move, the two rear wheels are enabled to veer along with the front wheels, and a vehicle achieves four-wheel steering.
Description
Affiliated technical field
The present invention relates to a kind of four-wheel steering assembly.
Background technology
At present, existing vehicle is agricultural vehicle such as sower employing two-wheeled or four-wheel steering particularly, and two-wheeled turns to because Turning radius is larger, is not easy to farmland operation, although four-wheel steering is convenient to farmland operation, makes because Turning radius is too little when road driving and handle difficulty.
Summary of the invention
Can only two-wheeled turn to or the defective of four-wheel steering in order to overcome existing agricultural vehicle, the invention provides a kind of four-wheel steering assembly, it can realize easily that two-wheeled turns to or four-wheel steering.
The technical solution adopted for the present invention to solve the technical problems is: the near front wheel, left front spindle arm, left front steering shaft, front tension bar, right front spindle arm, off front wheel, right front steering shaft, driving lever, rotation connecting lever, spring, eccentric shaft, follower lever, right back steering shaft, off hind wheel, right back spindle arm, back stay, left back steering shaft, left back spindle arm, off hind wheel are linked in sequence.Left front steering shaft, right front steering shaft, right back steering shaft, left back steering shaft maintain static, left front spindle arm can rotate around left front steering shaft, right front spindle arm can rotate around right front steering shaft, right back spindle arm can rotate around right back steering shaft, and left back spindle arm can rotate around left back steering shaft, and an end of driving lever can slide in follower lever, driving lever has a groove near the one side of eccentric shaft, eccentric shaft is connected with follower lever, and can rotate on follower lever, and eccentric shaft is connected with the rotation connecting lever.when needing two-wheeled to turn to, handle and rotate connecting lever, the eccentric shaft rotation makes damaged facing to driving lever, eccentric shaft can not stop driving lever to slide in follower lever, when handling steering hardware, driving left front spindle arm rotates, front tension bar moves, thereby driving right front spindle arm rotates, the off front wheel that is connected to the near front wheel on left front spindle arm and is connected on right front spindle arm is realized turning to, driving lever also seesaws thereupon simultaneously, because eccentric shaft does not link into an integrated entity driving lever and follower lever, therefore follower lever can not move thereupon, thereby left rear wheel, off hind wheel is not with the near front wheel, off front wheel turns to, vehicle realizes that two-wheeled turns to, when needing four-wheel steering, handle and rotate connecting lever, make the damaged face of eccentric shaft leave driving lever, eccentric shaft just enters in the groove of driving lever, eccentric shaft just stops driving lever to slide in follower lever like this, driving lever and follower lever are connected as one, and when handling steering hardware, the near front wheel and off front wheel turn to, driving lever also seesaws thereupon simultaneously, follower lever also can move thereupon, drives right back spindle arm and rotates, and off hind wheel turns to, drive simultaneously the back stay motion, left back spindle arm is rotated, and left rear wheel turns to thereupon, and the four-wheel of vehicle is realized turning to simultaneously like this.
The invention has the beneficial effects as follows, can be under different operating modes, vehicle realizes that easily two-wheeled turns to and four-wheel steering, control comfort is simple in structure.
