Description

Technical Field

[0001] The present application relates to the technical field of steering regulation, and in particular to a steering synchronization mechanism. Background Art

[0002] Wheeled engineering or special vehicles usually need a smaller turning radius to improve their site applicability and enable them to operate flexibly in a narrower space. In addition, in order to reduce the fuel consumption of the whole machine and increase the service life of the tires, the tires must be kept in a pure rolling state during driving to avoid tire side slipping. For this purpose, the steering angle of each wheel must be accurately controlled.

[0003] In the related technology, multi-wheel or all-wheel steering is often used to achieve this goal. Multi-wheel steering requires the coordination of the steering angles of each wheel group during the steering process. The existing steering synchronization has the following technical routes: 1) pure mechanical mechanism synchronization device; 2) electronically controlled synchronization; 3) synchronous cylinder synchronization.

[0004] Pure mechanical synchronization devices, such as rods, gears, and chains, require a large space and are inconvenient to arrange, and some are even impossible to implement. Although electronically controlled steering synchronization is easy to arrange, it requires more detection and servo components to control the angle coordination, which is relatively expensive. Synchronous cylinders will cause cumulative errors due to processing accuracy issues. Summary of the invention

DETAILED DESCRIPTION

[0071] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings.

[0072] In the description of this specification, the description with reference to the terms "certain embodiments", "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0073] The present application embodiment discloses a steering synchronization mechanism. Figure 1 As an embodiment of the steering synchronization mechanism, the steering synchronization mechanism may include two steering cylinders 110 and an intermediate cylinder 120. The two steering cylinders 110 are respectively mounted on the left front wheel assembly 101 and the left rear wheel assembly 102, and are arranged symmetrically; the intermediate cylinder 120 is mounted on the vehicle frame and is of the same specification as the two steering cylinders 110. The rod chamber of one steering cylinder 110 is connected to the rod chamber of the intermediate cylinder 120, and the rodless chamber of the intermediate cylinder 120 is connected to the rodless chamber of the other steering cylinder 110.

[0074] When oil flows into the rodless cavity of a steering cylinder 110, the steering cylinder 110 extends by a length X, and the rod cavity of the steering cylinder 110 is connected to the rod cavity of the middle cylinder 120, so the middle cylinder 120 correspondingly retracts by a length X, and the rodless cavity of the middle cylinder 120 is connected to the rodless cavity of another steering cylinder 110, so the steering cylinder 110 also extends by a length X accordingly. Since the two steering cylinders 110 are symmetrically arranged, it can be ensured that the moving trajectories (A and B) of the left front wheel assembly 101 and the left rear wheel assembly 102 are equal during the dynamic process.

[0075] Reference Figure 2 As another implementation of the steering synchronization mechanism, the steering synchronization mechanism may further include a pressure block 210 , a pressure plate 220 , a detection block 230 and a pressure sensor 240 .

[0076] Among them, the pressure block 210 is coaxially fixedly connected to the piston rods of the steering cylinder 110 and the intermediate cylinder 120, and the pressure plate 220 is fixedly connected to the pressure block 210. The detection block 230 is set corresponding to the pressure block 210 and installed on the frame. The pressure sensor 240 is installed on the corresponding detection block 230, and the pressure plate 220 can abut against the pressure sensor 240. Take the intermediate cylinder 120 as an example; when the pressure data corresponding to the intermediate cylinder 120 is within the preset pressure threshold range (the pressure value range when the cylinder extension length is normal), it means that the extension of the intermediate cylinder 120 is correct.

[0077] Furthermore, in order to assist the extension of the oil cylinder when the oil cylinder is not extended enough, a driving electric push rod 250 is horizontally mounted on the detection block 230, and a mounting bracket 260 is fixedly connected to the telescopic end of the driving electric push rod 250. A two-way oil cylinder 261 is mounted on the mounting bracket 260, and clamping blocks 262 are fixedly connected to both piston rods of the two-way oil cylinder 261, and the clamping blocks 262 are adapted to the oil cylinder piston rod to clamp the piston rod of the oil cylinder.

Take the middle cylinder 120 as an example:

[0079] The pipeline conversion assembly 300 may include a connection plate 310 , an oil delivery hose 320 , and an opening and closing component 330 .

[0080] Reference Figure 3 and Figure 4The connecting plate 310 may include an oil inlet block 313, an oil outlet block 314 and an oil transfer pipe 315.

[0083] Among them, the opening and closing column 331 is arranged corresponding to the oil outlet hole 312, and is slidably connected to the oil outlet block 314 to open and close the oil outlet hole 312. The opening and closing block 332 is fixedly connected to one end of the opening and closing column 331 close to the oil ferry 315, and this end of the opening and closing column 331 is placed outside. The support rod 336 is coaxially fixedly connected to this end of the opening and closing column 331, and the return spring 334 is coaxially sleeved on the support rod 336, and the support block 335 is slidably connected to one end of the support rod 336 away from the opening and closing column 331, and abuts against the oil inlet block 313. The support rod 336 is slidably connected to the oil inlet block 313. When the opening and closing column 331 slides in the direction close to the oil inlet block 313, the opening and closing column 331 opens the oil outlet hole 312, and the return spring 334 is compressed.

[0084] The push block 333 is rotatably connected to the oil outlet block 314 to push the movement of the opening and closing block 332. The rotating part 340 is installed on the oil outlet block 314 to drive the rotation of the push block 333.

[0085] The rotating part 340 includes a rotating motor 341 and a rotating disk 342. The rotating motor 341 is installed on the end surface of the oil outlet block 314 away from the oil transfer pipe 315, and the output shaft passes through the oil outlet block 314 and is rotatably connected to the oil outlet block 314. The rotating disk 342 is coaxially fixedly connected to one end of the output shaft passing through the oil outlet block 314. There is one push block 333, which is fixedly connected to the edge of the rotating disk 342.

[0086] Further, refer to Figure 3 and Figure 6 The pipeline conversion assembly 300 also includes a connection shell 350, which is sleeved on the connection disk 310 and is detachably connected to the connection disk 310.

[0087] In order to realize the detachable connection between the connecting shell 350 and the connecting disk 310, a rotating gear 361 is coaxially connected to the oil outlet block 314 through an end face bearing, and rotating racks 362 are meshed at both ends of the diameter of the rotating gear 361. The separated ends of the two rotating racks 362 are fixedly connected with locking plates 363, and the locking plates 363 are slidably connected to the oil outlet block 314. Anti-slip plates 364 are fixedly connected at both ends of the diameter of the connecting shell 350, and the locking plates 363 can be clamped on the corresponding anti-slip plates 364.

[0088] In order to achieve the locking of the rotating gear 361, a synchronous block 365 is coaxially fixedly connected to the output shaft of the rotating motor 341, a rotating block 366 is rotatably connected to the synchronous block 365, a rotating nut 367 is threadedly connected to the rotating block 366, and the rotating nut 367 can be threadedly connected to the rotating gear 361. After the rotating nut 367 is separated from the rotating gear 361, the rotating gear 361 can be driven to rotate.

[0089] Furthermore, an auxiliary plate 368 is connected to the oil inlet block 313 so as to slide toward or away from each other, and an auxiliary rod 369 is fixedly connected to the auxiliary plate 368. Two auxiliary blocks 371 are fixedly connected to the oil inlet block 313, and the auxiliary rod 369 passes through the corresponding auxiliary block 371 and is connected to the auxiliary block 371 in a sliding manner. An auxiliary spring 372 is coaxially sleeved on the auxiliary rod 369, and the auxiliary spring 372 is used to realize the reset of the auxiliary plate 368 after sliding. Auxiliary tightening blocks 373 are fixedly connected to both ends of the diameter of the connecting shell 350, and the auxiliary plate 368 can be clamped in the corresponding auxiliary tightening blocks 373. After the auxiliary plate 368 is separated from the auxiliary tightening block 373, the auxiliary plate 368 compresses the auxiliary spring 372.

[0090] Reference Figure 7 As another embodiment of the steering synchronization mechanism, the steering synchronization mechanism may further include a camera 410, which is mounted on the vehicle frame and is in communication connection with the controller 420, for collecting image information at the steering cylinder 110 and the intermediate cylinder 120, and transmitting the image information to the controller 420, which identifies the image information to determine whether oil leakage occurs. In addition, the pressure sensor 240, the rotary motor 341 and the driving electric push rod 250 are all in communication connection with the controller 420.

[0091] The bidirectional cylinder 261, the steering cylinder 110 and the intermediate cylinder 120 are all provided with hydraulic oil by a hydraulic pump, and the hydraulic pump is communicatively connected with the controller.

[0092] The implementation principle of this embodiment is:

[0093] When the steering cylinder 110 on the left front wheel assembly 101 has no rod chamber filled with oil, the steering cylinder 110 extends by a length X, the middle cylinder 120 retracts by a length X accordingly, and the steering cylinder 110 on the left rear wheel assembly 102 also extends by a length X accordingly. Since the two steering cylinders 110 are symmetrically arranged, it can be ensured that the movement trajectories of the left front wheel assembly 101 and the left rear wheel assembly 102 are equal during the dynamic process;

[0094] When it is determined that oil leakage has occurred based on the image captured by the camera 410, the rotary motor 341 can be controlled to start, and the rotary motor 341 can drive the rotary disk 342 to rotate, thereby moving the push block 333 and driving the next opening and closing column 331 to move to open the oil outlet 312. When the push block 333 is separated from the current opening and closing block 332, the current opening and closing column 331 closes the current oil outlet 312 under the elastic force of the reset spring 334, thereby allowing the new oil delivery hose 320 to deliver oil.
