Six-wheel independent drive chassis system
The obstacle crossing (crossing over a 60cm step) can be realized through a complex combined pavement consisting of a soft pavement (such as a soft concrete pouring layer), a wading pavement, a slope pavement, a narrow pavement and the like. In order to pass through the off-road property of the robot, the robot is ensured not to sink when passing through a soft road surface, and in addition to the adoption of the crawler wheels, the robot is required to have balanced traction force of each driving wheel under various complicated road surface conditions. In order to ensure the driving safety of the vibrating robot, the robot is required not to tip over when passing through a slope road surface, the robot is ensured to have enough traction force when passing through a smooth road surface, and the robot is required to have better smoothness when passing through an uneven road surface.
(1) Independent drive system and control
6 wheels are independently driven by 6 hydraulic motors respectively, and the 6 hydraulic motors are divided into two groups, the three motors on the left side are one group, the three motors on the right side are one group, power is provided by the constant power variable plunger pumps controlled by 2 electro-hydraulic proportions respectively, and the shunt is utilized for shunting. In order to ensure the stability of the vehicle in straight line running, the traction balance of 6 motors needs to be ensured; meanwhile, the flow of the driving wheels on the same side is automatically distributed on the basis of ensuring balanced traction by utilizing a liquid resistance control technology. When one or more motors idle due to the fact that the road surface is too slippery or a pit is trapped, the power of the one or more motors needs to be cut off and is automatically distributed to other driving wheels, so that each driving motor needs to be independently controlled, the running state of the driving motor (including parameters such as the rotating speed of the motor and the pressure of an oil inlet and an oil outlet) is monitored in real time, and a control system carries out corresponding adjustment according to the parameters.
(2) Adaptive control active suspension system and control
When the off-road vehicle driven by 6X6 model and 8X8 model multiple shafts runs on the surface with extraordinary ruggedness, the vertical load of a certain driving wheel is reduced greatly due to the structure of an independent suspension, and even the off-road vehicle leaves the surface and is suspended, so that the driving wheel loses the adhesion with the surface and the trafficability of the driving wheel is influenced. The independent suspension and the balanced suspension allow larger relative displacement between the wheel and the frame, so that the driving wheel is always kept in contact with the ground, and better adhesion performance is ensured. Meanwhile, the independent suspension can remarkably improve the minimum ground clearance of the vehicle, so that the trafficability of the vehicle is improved.
The technology adopts 6 crawler wheels, active suspension is realized by 6 hydraulic cylinders respectively, a displacement sensor and a pressure sensor are installed on each hydraulic cylinder, and a control system monitors the state of each hydraulic cylinder at any time so as to ensure that the robot has good trafficability under different road conditions. When the robot runs on a flat road, all the 6 hydraulic cylinders retract, and the passive suspension is realized by a hydraulic system, so that the ground clearance of the robot is minimum, the gravity center of the robot is reduced, and the safety of the robot during high-speed running is improved; when the crawler wheels pass through an uneven road surface, the control system detects the state of each crawler wheel, and if the front surface of each crawler wheel is provided with a pit, the oil cylinder is controlled to extend outwards until the crawler wheels are reliably contacted with the ground; if the obstacle with the bulge in the front is detected, the control oil cylinder is sequentially retracted, and the crawler wheels are reliably contacted with the ground in the process. If one track wheel exceeds the adjusting range of the oil cylinder due to the fact that the pit is too deep, the control system needs to cut off the power of the track wheel and distribute the power to other driving wheels.
(3) Independent steering system and control
The driving wheels 6.1.2 can realize steering through the independent steering hydraulic motors 6.3, and each driving crawler 6.1.3 can realize independent steering.
The using method comprises the following steps: when the driving crawler belt 6.1.3 turns, the independent turning hydraulic motor 6.3 is started to drive the gear to rotate, the gear is meshed with the rack on the crawler belt supporting plate 6.1.4 to drive the driving crawler belt 6.1.3 to rotate in the horizontal direction, and then the turning of the driving crawler belt 6.1.3 is realized.
The adoption of the independent drivingcrawler belt device 6 can realize that:
step of turning over 60cm high
The multi-wheel independent driving and self-adaptive active suspension system adopted by the vibrating robot can easily cross a step obstacle with the height of 60 cm.
② passing through uneven road surface
When the robot runs on a rough road surface, factors influencing the trafficability of the robot mainly include the overall dimension, the tire diameter, the driving form and the like of the whole vehicle. The approach angle, departure angle and minimum ground clearance in the robot dimensions have the greatest influence on the trafficability of the robot, which must be large enough otherwise the vehicle is inserted underground during travel or because the approach angle is too small; or the rear bridge is lifted due to the undersize departure angle; or the robot is firmly caught due to the fact that the minimum ground clearance is too small; or the robot is set up because the transverse and longitudinal pass radii are too large. These phenomena all cause the robot to "ground".
Conventional transaxle vehicles typically employ multiple axles; the longitudinal or transverse passing radius can be reduced by shortening the wheel track or the wheel base and the like; adopting a large-diameter tire; front overhang and rear overhang are reduced; the positions of components such as an oil tank, a silencer and an oil pan of an engine are improved, and the trafficability of the robot is improved by adopting a wheel edge speed bridge with a large ground clearance. After the technology is adopted, the 6 crawler wheels are independently driven by the 6 hydraulic motors respectively, and because a traditional drive axle is cancelled, a drive axle intermediate differential mechanism 'large bulge' which directly influences the ground clearance does not exist, the ground clearance can be greatly improved, and the geometric obstacle crossing capability is improved. The driving forces of the 6 crawler wheels are mutually independent, and the crawler wheels have reliable independent driving capability under any condition, so that the attachment passing capability is strong, and the cross-country capability and the traction capability are improved. The hydraulic transmission ratio is easier to distribute and control power than mechanical transmission, and the robot can control the power very easily, so that the conversion of two-wheel drive, four-wheel drive and six-wheel drive can be realized conveniently. Under the condition of off-road running, the soil has certain elasticity, and the ground also has certain unevenness, so that the vertical vibration of the robot and the torsional vibration of the transmission system parts can be caused. Such vibrations not only make it difficult for the operator to tolerate, fatigue damage to the parts of the running gear and drive train, but also severely affect the passing performance of the machine if the vehicle speed is high. After the technology is adopted, the active suspension is realized by adopting the hydraulic oil cylinder, so that the smoothness of the robot in the running process can be greatly improved.
Ability to pass through soft road surface
When the robot passes through a soft road surface, the track wheels sink to a greater depth than when the robot travels on a hard road surface, so that the resistance of the road surface to the track is large. In order to make the track sink to a small depth when running on a soft road, it is necessary to reduce the pressure of the track against the ground. Increasing the ground-contact area of the track is one of the most desirable solutions to the above-mentioned problems. By adopting a multi-wheel independent driving mode and a self-adaptive active suspension system, the weight of the whole robot can be uniformly distributed on each crawler wheel, and the ground pressure of the robot is reduced. Meanwhile, all the crawler wheels can provide traction force, so that the original driven wheel is changed into the conventional driving wheel, and therefore, the friction force between the driven wheel and the road surface does not exist, and the running resistance of the robot is greatly reduced. If some crawler wheels of the robot are slipped or overhead for some reasons, the hydraulic system can conveniently cut off the power of the crawler wheels and distribute the power to other crawler wheels which are in firm contact with the ground and have high adhesion force, and the driving is continued.
Capability of passing through gradient road surface
Because the six-wheel independent active suspension system is adopted, when the robot runs on a road surface with large gradient or a side slope, the inclination sensor arranged on the main frame can adjust the displacement of each oil cylinder through the electric control system, so that the gravity center of the robot is kept in a certain range, the robot has larger climbing capacity, and the robot cannot roll over when running on a larger side slope.
The foregoing description is only exemplary of the preferred embodiments of the application and is provided for the purpose of illustrating the general principles of the technology and the like. Meanwhile, the scope of the invention according to the present application is not limited to the technical solutions in which the above-described technical features are combined in a specific manner, and also covers other technical solutions in which the above-described technical features or their equivalent are combined arbitrarily without departing from the inventive concept described above. For example, the above features may be replaced with (but not limited to) features having similar functions disclosed in the present application.
