Detailed Description
Embodiments of the present invention will be described in more detail with reference to the accompanying drawings, but it should be understood that the description is only for the purpose of helping those skilled in the art better understand the present invention, and the present invention is not limited to the listed embodiments.
The utility model relates to a wheeled agricultural machinery rear axle that floats to and use this wheeled agricultural machinery of rear axle that floats. In the following description, a sugarcane harvester is described as an example of a wheeled agricultural machine.
Fig. 1 is an overall schematic view of an agricultural floating rear axle assembly according to an embodiment of the present invention; fig. 2 is a projection view of a rear right axle assembly of an agricultural machine according to an embodiment of the present invention.
As shown in fig. 1, a floating rear axle of a wheeled agricultural machine (e.g., a sugarcane machine) according to an embodiment of the present invention includes two parts: the left rear axle assembly and the right rear axle assembly are designed in a symmetrical structure. Since the left and right rear axle assemblies are symmetrical and have the same specific structure, only the specific structure of the right rear axle assembly will be described below.
As shown in fig. 2, in the right rear axle assembly, the tire 1 is assembled with the rim 2, and the rim 2 and the web 18 are assembled and fixed by the bolts 17. The hydraulic motor 4 (floating hydraulic motor for the right rear wheel) and the web 18 are assembled and fixed by bolts 9. One end of a hydraulic motor 4 is connected with one end of the rear bridge 3, and the other end is connected with the rim 2; the hydraulic motor 4 is driven by a hydraulic pump connected with a power take-off port of the engine, and the oil cylinder is extended and shortened through a solenoid valve block. The wheels are assembled on the hydraulic motor, the hydraulic motor and the hydraulic motor move synchronously, and the hydraulic motor 4 pushes the wheels to move forwards and backwards and is not used for realizing the up-and-down floating of the wheels.
The other end of the rear bridge frame 3 is arranged on a whole agricultural machinery frame (not shown) through a pin shaft 8 for fixed support. In order to prevent the pin shaft 8 from rotating and moving, the assembly limiting and fixing are carried out through the pressing plate 15 and the bolt 14.
One end of the floating oil cylinder 6 is connected with the frame body of the rear bridge frame 3 through a pin shaft 7, and in order to prevent the pin shaft 7 from rotating and moving, the pin shaft 7 is assembled and fixed through a pressing plate 10 and a bolt 11. The other end of the floating oil cylinder 6 is connected to the whole vehicle frame through a pin shaft 5, and in order to prevent the pin shaft 5 from rotating and moving, the pin shaft 5 is fixedly installed through a pressing plate 12 and a bolt 13. According to one embodiment, the floating cylinder 6 is a plunger cylinder. When the electromagnetic proportional valve receives the signal, the hydraulic loop is controlled, oil is filled into or discharged from the oil cylinder, and the oil cylinder is stretched.
Fig. 3 shows a schematic view of the connection of the floating cylinder 6 to the rear bridge 3 according to an embodiment of the present invention. As shown in fig. 3, a notch is formed in the pin 7, the pressing plate 10 is matched with the notch, the pressing plate is fixed on the rear bridge frame 3 through a bolt 11, and the rear bridge frame 3 is provided with a threaded hole. The pin shaft fixing mode can be selected in various ways, and mainly aims to achieve the purpose of preventing the pin shaft from moving. The pressure plate 15 and the bolt 14 are used for limiting and fixing the pin shaft 8 in the same way. The floating oil cylinder is connected with the rear bridge through a pin shaft, and the pressing plate is only used for fixing the pin shaft and preventing the pin shaft from axially moving and is not directly connected with the floating oil cylinder.
Because one end of the rear bridge frame 3 is fixed on the whole machine frame, and the frame body of the rear bridge frame 3 is connected with one end of the floating oil cylinder, when the piston rod of the floating oil cylinder 6 stretches, the rear bridge frame 3 can be driven to rotate around the pin shaft 8. At the same time, the rear bridge 3 is fixed on the wheel, so that the wheel is driven to move up and down when rotating. The up-and-down floating of the wheel is achieved by the rotation of the rear bridge 3 around the pin 8, i.e. the wheel together with the motor and the subsequent bridge rotate around the pin.
When uneven or hollow lands appear on the road surface, the left rear axle and the right rear axle send signals by means of intelligent electronic leveling equipment, the hydraulic device (an electromagnetic proportional valve) is started, the floating oil cylinder 6 stretches, and the rear bridge 3 rotates around the pin shaft 8 to enable the tire 1 to swing up and down to further adjust the balance of the whole vehicle, so that the tilting angle is increased.
In one embodiment, the agricultural machine is provided with an engine, a hydraulic pump and an electromagnetic proportional valve, wherein the engine drives the hydraulic pump, the hydraulic pump is connected with the electromagnetic proportional valve, and the electromagnetic proportional valve is connected with a floating oil cylinder. The electromagnetic proportional valve controls the opening and closing of the hydraulic circuit, works (the opening and closing of an oil way and the flow can be controlled to realize the stretching and retracting speed control of the oil cylinder) when the tilt sensor feeds back signals, and realizes the stretching and retracting of the floating oil cylinder according to operation requirements.
When the vehicle travels, a hydraulic device gives a driving instruction to drive the hydraulic motor 4 to rotate to drive the tire to travel forwards or backwards, and the left rear axle and the right rear axle can independently execute up-and-down floating actions, so that the steering differential speed of the axles controls the speed difference through hydraulic control flow to realize steering, and the traveling speed is completely controlled by hydraulic pressure.
The utility model discloses a tire rotates by two hydraulic motor drives in both sides, and hydraulic motor is controlled by two electromagnetism proportional valve respectively, through controlling (case aperture size decision flow size) to the electromagnetism proportional valve, the flow of hydraulic motor can be distributed according to the operation demand for the output, and when both sides flow size formed the difference, both sides hydraulic motor's rotational speed was different, and the both sides tire forms the speed difference, realizes turning to of complete machine. The motor driving the rotation is separate from the motor realizing the floating.
How the electronic leveling apparatus determines the unevenness of the roadway and how the leveling is controlled can be accomplished by any method known to those skilled in the art now and in the future. For example, unevenness correction and sensing of road surface unevenness are achieved by tilt sensors (which, as the name suggests, sense inclination deviation angles). The inclination angle of the whole vehicle can be detected, when the inclination angle is larger than 10 degrees, the inclination angle sensor feeds back, the electromagnetic proportional valve works (the opening and closing of an oil way and the flow can be controlled to realize the stretching of the oil cylinder and the speed control of the stretching speed), and the stretching of the floating oil cylinder is realized according to the operation requirement.
The scope of the invention is defined by the appended claims, and the description is only intended to be read in the light of the claims, and all changes and modifications that can be made to the embodiments are within the scope of the invention as defined by the appended claims.
