(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the steering transmission linkage that a kind of vehicle steering is easy to adjust, laborsaving, the new automobile of stable operation is used the pneumatic adjustment of extension spring boosting belt is provided.
The purpose of this utility model is achieved in that the steering transmission linkage of a kind of new automobile with the pneumatic adjustment of extension spring boosting belt, comprise column assy, servomechanism and pneumatic adjusting mechanism, described column assy comprises steering column, fixed support and sliding support, fixed support links to each other with cab mounting and is fixing, sliding support is connected with steering column and is fixing, described servomechanism comprises extension spring, described extension spring has two, two extension springs are arranged in described support bracket fastened two sides, one end of this extension spring links to each other with fixed support, the other end links to each other with sliding support, but slide relative between fixed support and the sliding support, described pneumatic adjusting mechanism comprises cylinder, latch and lockable mechanism, described lockable mechanism comprises short latch segment and long latch segment, described short latch segment and the overbolt cross-under of long latch segment, described short latch segment and long latch segment are connected on fixed support and the sliding support, described cylinder links to each other with an end of latch, the other end of latch is the working end, concave-convex type is made in described latch working end, described latch working end is embedded between described short latch segment and long latch segment two driving surfaces in opposite directions, corresponding to the concave-convex type working end of described latch, the driving surface with matching of described short latch segment and long latch segment also is arranged to concave-convex type.
Utility model provides power by source of the gas, the adjustment of opening or stopping tight lockable mechanism assurance vehicle steering.Promptly when connecting source of the gas, cylinder operation, this moment, lockable mechanism was opened adjustable whole bearing circle.When disconnecting source of the gas, cylinder makes lockable mechanism be in locking state under the contained spring effect, and bearing circle is fixed.
The beneficial effects of the utility model are:
And servomechanism is the auxiliary power-assisted when solving bearing circle and adjusting upward.The effect of servomechanism is when bearing circle is adjusted to arbitrary position downwards, when adjusting upward, needs are subjected to extended state again because extension spring this moment is in, extension spring has the characteristic that restPoses automatically after the distortion, this moment steering column is resetted to play the autoamtic boosting effect.Adopt the both sides extension spring, can make power-assisted balanced consistent, adjustment process steadily, easily.Therefore easy to adjust, laborsaving, stable operation.

Fig. 2 is the left side view of Fig. 1.
Fig. 3 is a pneumatic adjusting mechanism structural representation of the present utility model.
Among the figure: steering column 1, pneumatic adjusting mechanism 2, extension spring 3, fixed support 4, sliding support 5, cylinder 2.1, latch 2.2, short latch segment 2.3, long latch segment 2.4.
(5) specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to Fig. 1～2, the utility model new automobile is made up of column assy, servomechanism and pneumatic adjusting mechanism 2 with the steering transmission linkage of the pneumatic adjustment of extension spring boosting belt.Described column assy comprises steering column 1, fixed support 4 and sliding support 5, and described fixed support 4 links to each other with cab mounting and be fixing, and sliding support 5 is connected with steering column 1 (bearing circle) and is fixing.Described servomechanism comprises extension spring 3, extension spring 3 has two, two extension springs 3 are arranged in two sides of described fixed support 4, one end of this extension spring 3 colludes on fixed support 4, the other end colludes on the following bolt of sliding support 5, fixed support double side acting power is even when guaranteeing power-assisted, changes in the past by middle gas spring power-assisted energy imbalance.But slide relative between fixed support 4 and the sliding support 5.Two extension springs can produce distortion along with the variation of fixed support and sliding support relative position.Sliding support links to each other with column jecket, driving sliding support when column jecket is adjusted moves, drive extension spring simultaneously and produce displacement, when being stretched to arbitrary position, both sides extension spring this moment is in the tension deformation state, and it must have a kind of characteristic that self resets, as long as on bearing circle, add some power a little, the sliding support part just can realize power-assisted resetting to virgin state easily, plays the power-assisted effect during to adjustment.
Referring to Fig. 3, described pneumatic adjusting mechanism 2 is made up of cylinder 2.1, latch 2.2 and lockable mechanism.Described lockable mechanism is made of short latch segment 2.3 and long latch segment 2.4.Described short latch segment 2.3 and long latch segment 2.4 overbolt cross-under, described short latch segment 2.3 and long latch segment 2.4 are connected on fixed support 4 and the sliding support 5, described cylinder 2.1 links to each other with an end of latch 2.2, the other end of latch 2.2 is the working end, concave-convex type is made in described latch 2.2 working ends, described latch 2.2 working ends are embedded between described short latch segment 2.3 and long latch segment 2.4 two driving surfaces in opposite directions, concave-convex type working end corresponding to described latch 2.2, the driving surface with matching of described short latch segment 2.3 and long latch segment 2.4 also is arranged to concave-convex type, the combined action that cooperatively interacts of the working end of described latch and short latch segment and long latch segment
In Fig. 3,, can guarantee the adjustment and adjusted effectively the stopping tightly of bearing circle by the gap between short latch segment of control and the long latch segment.And the control of degree of tightness is herein realized by the relative distance that moves in or out with long latch segment of short latch segment.The control that long latch segment and short latch segment move is realized by the cylinder control of latch one end, Fig. 3 is the state when not ventilating the source, this moment, latch was in the tight state of bullet, by the tight latch of cylinder interior spring bullet, latch acts between long latch segment and the short latch segment (similar lever principle), and long latch segment and short latch segment are outwards moved simultaneously, and long latch segment and short latch segment are in the maximum displacement state, guarantee that setting device is in locking state, vehicle steering is in locking state.When connecting source of the gas, this moment, latch was in releasing orientation on the contrary, and long latch segment and short latch segment are moved inward simultaneously, and long latch segment and short latch segment are in the least displacement state, and bearing circle is in the state of can adjusting that unclamps.At this moment, adjustable turn over is to tubing string, and the effect of latch is similar to lever principle, and latch work is controlled by cylinder.The structure that adopts this air operated control lockable mechanism to adjust need not to adjust by rotary handle with hand-power.Adopt source of the gas as power, can guarantee the adjustment of bearing circle actv. fully and stop tight.
