Abstract
The invention discloses an all terrain crane and a suspension guide mechanism for steering axle and non-steering axle, wherein the suspension guide mechanism for steering axle comprises two lower thrust rods, two upper thrust rods and steering drag rod, which are horizontally arranged and the projection length sizes of them in the vehicle running direction are equal. The suspension guide mechanism for non-steering axle does not comprise steering drag rod. In the invention, by rationally configuring the upper and lower thrust rod and steering drag rod, the projection length sizes of them in the vehicle running direction are equal, so as to improve the motion coordination and stress condition and delay the release of the joint, thereby improving the stability of the operation and comfort and safety of the vehicle.
Description
Technical field
The present invention relates to the suspension system of vehicle, relate in particular to a kind of all terrain crane and use suspension guide mechanism.
Background technology
Continuous increase, being on the increase of vehicle bridge number and improving constantly of the speed of a motor vehicle along with all terrain crane deadweight; Because of the inharmonious braking deviation that causes and the interference of vehicle guidance mechanism turns to problem outstanding all the more, have a strong impact on vehicle handling and stability, take advantage of and drive traveling comfort and travel safety.
Wherein, term " braking deviation " is meant that the glancing impact vehicle can not keep straight-line travelling, toward some direction sideslips.One of reason is exactly that suspension guiding leverage and steering system pull bar move interference.
Term " interference turns to " is meant when the relative vehicle bridge generation of vehicle frame relative motion, and suspension guiding leverage and steering gear connection are inharmonious and interfere on kinematics, make the rotation of wheel flutter around stub, i.e. the change of wheel steering angle.
Term " road-holding property " is meant that the road-holding property of automobile is comprising two parts content that interknits, the one, and road-holding property, the 2nd, stability.Road-holding property is meant that automobile can be timely and accurately turns to by the steering order of chaufeur; After stability is meant that then automobile receives external interference, can recover the direction of cruising voluntarily, and back skating does not take place, topple, phenomenon such as out of control.
The suspension guide mechanism of at present domestic all terrain crane, its schematic construction is as shown in Figure 1, and two lower thrust rods 1 ' and two upper thrust rods 2 ' are installed on the suspension 4 ', and Reference numeral 3 ' is a steering drag link.Wherein, The distance of the rod end of two upper thrust rods 2 ' is L2, and the distance of its butt is L1, wherein; L1＞L2; Be down trapezoidal arrangement form, and generally do not consider or do not have the sports coordination of omnibearing consideration itself and steering gear connection, make vehicle more or less have braking deviation and roll steer phenomenon.
Wherein, term " roll steer " is meant vehicle frame generation inclination under the roll force effect, because the wheel flutter that causes of vehicle frame inclination is around the rotation of stub, non-wheel flutter winds the rotation perpendicular to the ground axis, i.e. the change of wheel turning angle.
The many bridges of mechanical type turn to all terrain crane particularly serious because of shimmy phenomenons of steered wheel former thereby that cause such as interference turns to, steering gear connection insufficient rigidity and guiding leverage joint gaps; Thereby influence hoisting crane braking ability, road-holding property, take advantage of and drive traveling comfort and travel safety, also aggravated the oil consumption of Tyte Wear and vehicle simultaneously.
Wherein, term " steered wheel is shimmy " is meant that fitfull up and down or side-to-side movement.Side-to-side movement just is meant the transverse runout of wheel or tire, and up-and-down movement just is meant the radially runout of wheel or tire.
Summary of the invention
One of the object of the invention is to provide a kind of all terrain crane steeraxle to use suspension guide mechanism; Another purpose of the present invention is to provide a kind of all terrain crane non-steering axle to use suspension guide mechanism, and the object of the invention also is to provide a kind of all terrain crane with suspension guide mechanism.
The present invention improves its sports coordination, improves its force-bearing situation and delay the loose wealthy of junction through the method for reasonable Arrangement guiding leverage and coupling leverage length dimension, to overcome the shortcoming of prior art.
For this reason; On the one hand; The invention provides a kind of all terrain crane steeraxle and use suspension guide mechanism, comprising: two lower thrust rods, two upper thrust rods and steering drag link, wherein; Two lower thrust rods, two upper thrust rods and steering drag link average level are arranged, and are all equated in the projected length size of vehicle heading.

Preferably, above-mentioned two upper thrust rods become the splayed configuration symmetric arrangement according to the vehicle frame line of centers, flexibly connect with bridge and vehicle frame, its in the connection spacing on the vehicle frame greater than its connection spacing on bridge.
Preferably, above-mentioned steering drag link is connected with track arm on the bridge through two ball pivots and vertical rocking arm.
Preferably, above-mentioned suspension is a hydro pneumatic suspension.
On the other hand, the invention provides and have all terrain crane of above-mentioned steeraxle with suspension guide mechanism.
Another aspect; The invention provides a kind of suspension guide mechanism of all terrain crane non-steering axle, comprising: two lower thrust rods and two upper thrust rods, wherein; Two lower thrust rods and two upper thrust rod average levels are arranged, and are all equated in the projected length size of vehicle heading.
Preferably, above-mentioned two lower thrust rods flexibly connect with bridge and vehicle frame according to the parallel symmetric arrangement of vehicle frame line of centers.
Preferably, above-mentioned two upper thrust rods become the splayed configuration symmetric arrangement according to the vehicle frame line of centers, flexibly connect with bridge and vehicle frame, its at the connection spacing L2 on the vehicle frame greater than its connection spacing L1 on bridge.
In addition, the present invention also provides and has had all terrain crane of above-mentioned non-steering axle with suspension guide mechanism.
Through lower thrust rod on the reasonable disposition and steering drag link; And lower thrust rod and steering drag link are equated in the projected length size of vehicle heading; Improved sports coordination, improved its force-bearing situation, delayed the loose wealthy of junction, and then improved vehicle handling and stability, take advantage of and drive traveling comfort and travel safety.
Except top described purpose, feature and advantage, the present invention also has other purpose, feature and advantage.Below will be with reference to figure, other purpose, characteristic and effect of the present invention done further detailed explanation.
