Face injustice situation improves the steady comfort of entire running gear, is especially particularly important when coping with hazmats.
Suspension mechanism 4 of the present invention is arranged at intervals on walking 14 two sides of frame, and 10 upper end of the steering arm insertion turns to
In linking arm 7, bolt 9, which passes through the connector 8 for turning to 7 upper end of linking arm and steering arm 10, will turn to linking arm 7 through nut check
It is fixedly connected with steering arm 10, so that after releasing the connector for turning to linking arm upper end, steering arm can be revolved around rotary shaft
Turn, steering arm enters in the groove for turning to connection, and the connector for turning to linking arm lower end connects through bolt, nut and steering arm are fixed
It connects, steering arm and turns to linking arm and be integrated part, tire is placed on the outside of walking frame, when the connector for turning to linking arm lower end
After releasing, steering arm is rotated, steering arm rotates around the axis, when steering arm and steering linking arm angle are 180 °, steering arm upper end
It is fixed by connector, bolt, nut with linking arm upper end is turned to, tire is placed on the inside of walking frame, shortens the width of vehicle
Degree, it is ingenious in design, it is easy to operate.
The present embodiment is illustrated so that frame two sides of walking are equipped with five groups of tires as an example, and every group of tire is oppositely arranged, often
A suspension mechanism is provided on a tire, the hanging oil cylinder on each suspension mechanism is each equipped with control valve, each control valve
It can individually manually control, can be connected in the control system on chassis, be controlled by control system, control system is existing
Vehicle control syetem, tire in motion used in steering system and braking system be all made of the prior art, swing arm can be with
It being connect with drive motor, the rotation of drive motor tire on the drive wheels, drive part is same as the prior art, it does not repeat, when normally travel,
Steering arm insertion turns in the groove of linking arm, and the connector for turning to linking arm lower end connects through bolt, nut and steering arm are fixed
It connects, linking arm will be turned to and steering arm is fixed as a component, tire, can normal walking and fortune on the outside of walking frame at this time
Loading object keeps the present invention under light condition, is then ensuring that entire walking mechanism is stable when needing transition to transport
In the case of, the control valve of first group, third group, the 5th group of suspension mechanism can be opened, hanging oil cylinder is stretched out, and such first
Group, third group, the 5th group of tire are pressed downward, and second group and the 4th group of tire can be detached from ground, close first group, third
The control valve of group, the 5th group of suspension mechanism by steering arm on second group and the 4th group of suspension mechanism and turns under linking arm
The connector at end is removed, and steering arm is then rotated 180 ° around steering shaft, steering arm drives swing arm, tire rotation, by tire
It is transferred on the inside of walking frame, is then fixedly connected with steering arm upper end with linking arm upper end is turned to through bolt, connector, nut,
And so on, four tires on second group and the 4th group are all rotated on the inside of walking frame, then opens second group and the
The control valve of hanging oil cylinder is stretching out one after the tire of second group and the 4th group contacts ground down on four groups of suspension mechanisms
A bit, promote first group, third group, the 5th group of tire disengaging ground, close the control of hanging oil cylinder on second group, the 4th group
Valve, then by the steering arm of each hanging oil cylinder on first group, third group, the 5th group and and turn to linking arm lower end connector
It removes, steering arm is then rotated 180 ° around steering shaft, steering arm drives swing arm, tire rotation, and tyre revolution is entered frame of walking
On the inside of frame, then steering arm upper end is fixedly connected through bolt, connector, nut with linking arm upper end is turned to, in this way, by first
Group, third group, all tire is transferred on the inside of walking frame on the 5th group, then starts second group and the 4th group of hanging oil cylinder
It withdraws or starts the hanging oil cylinder on first group, third group, the 5th group and stretch out, promote five groups of entirely walking frame two sides
Tire with ground face contact, keeps structure steady, then starts transition transport, above-mentioned to enter on the inside of frame of walking by tyre revolution
When, first which group tyre revolution is entered to walk on the inside of frame, first which group tire can be lifted, connector is then torn open, after rotation
It is fixed, it can be completed according to the habit of operator, premise is to maintain entire walking mechanism stability under loading and does not incline securely and reliably
Tiltedly, easy to operate, it adjusts quickly, compared with prior art, each tire is rotated and walked in transition operation by the present invention
On the inside of frame, the width of vehicle is shortened, avoids the need for the case where removing part, also there is no reinstall and part is lost
The case where, transition efficiency is substantially increased, the applicability of loading machine has also been widened.
In addition, the present invention, when walking is unfolded, tire is respectively positioned on the outside of walking frame, and hanging oil cylinder is adjusted to interposition
It sets, opens the control valve of hanging oil cylinder on all tire, accumulator is connect with hanging oil cylinder, when Uneven road, the hole on road surface
Hollow low-lying area situation is passed to tire, and swing arm is passed to after tire force, and swing arm passes to the hanging oil cylinder hinged with it, hangs
It hangs cylinder force and passes to accumulator, accumulator drives hanging oil cylinder to retract or stretch out, tire is promoted to answer road pavement rugged
Uneven situation, it is ensured that entire walking mechanism is steadily comfortable, and especially in the frangible article of load danger, the balance of car body is just shown
It obtains particularly important；When evenness of road surface, the hanging oil cylinder of all suspension mechanisms can be retracted, close respective control valve, promote
Entirely the center of gravity of walking mechanism drops to minimum, and for support wheel away from reaching maximum, entire walking mechanism reaches most stable, safest
State, it is ensured that walking and transportation safety.
The present invention is due to using the above structure, having wheelspan overall width that can become smaller, transition is not necessarily to dismantle component, failure rate
Low, the advantages that stability is high, safe and reliable.
