Description

Technical Field

[0001] The utility model relates to the technical field of steering systems, in particular to a hydraulic steering system and a kart boat using the steering system. Background Art

[0002] In existing small boat steering systems, the rudder and the deflector are mostly connected by steel cables or transmission rods, such as the marine steering system proposed in Chinese patent application number "CN201510230642.5". This type of transmission method has a complex and large transmission structure and a relatively fixed layout position. It not only takes up a large amount of space, but also makes it difficult to freely change the position of the transmission structure according to needs. It is very inconvenient to deploy it on small and diverse ships such as small boats and karts. In addition, the transmission structure is mostly arranged on the bottom of the ship. Its metal structure is easily corroded when in contact with water, which increases maintenance costs. If corrosion-resistant materials are used, the production cost will increase. In addition, the existing structure using steel wire transmission is difficult to calibrate when the steering wheel deviates, and its transmission friction is large, which increases the difficulty of control.

[0003] Based on the above-mentioned shortcomings of the existing technology, this case will propose a new steering system, which can be better applied to ships such as karts, and has the advantages of simple transmission structure, low cost, and strong durability. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art such as complex and bulky structure, high difficulty in maintenance and calibration, poor durability, etc., and to propose a hydraulic steering system and a kart using the steering system.

[0007] Preferably, the first steering portion and the second steering portion are oriented in opposite directions to ensure that the rotation direction of the active side is consistent with the rotation direction of the driven side.

[0008] Preferably, the first steering part and the second steering part both include a first shell, two groups of sliding grooves are provided inside the first shell, a first rotating groove is provided between the two groups of sliding grooves, sliding rods are slidably installed inside the two groups of sliding grooves, a gear disk for engaging with the two groups of sliding rods is rotatably installed inside the first rotating groove, an external connecting disk for connecting to an external structure is provided through one side of the gear disk, and two groups of first interfaces are provided on one side of the first shell that are respectively connected to the two groups of sliding grooves.

[0009] Preferably, both ends of the sliding rod are sleeved with sealing rings that can slide and abut against the inner wall of the sliding groove.

[0010] Preferably, a connecting groove is provided between the tail ends of the two groups of sliding grooves.

[0011] Preferably, the inner diameter of the first interface and the pipeline should be larger.

[0012] Preferably, a return system is connected between the first steering part and the second steering part through a pipeline, and the return system includes a second shell, two groups of first passages are opened through the interior of the second shell, a second passage is connected between the two groups of the first passages, a rotary valve that acts as a switch is rotatably installed inside the second passage, both ends of the two groups of the first passages are connected to the second interface, and the four groups of the second interfaces are connected to the first interface through the pipeline.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1 、 2 4. Here is an example of the implementation of the hydraulic steering system:

[0030] A hydraulic steering system includes a first steering portion A1 and a second steering portion A2. The first steering portion A1 and the second steering portion A2 are connected by a pipeline 3. The first steering portion A1, the second steering portion A2, and the pipeline 3 are filled with a liquid for transmission. The first steering portion A1 is installed on the active side of an external device, and the second steering portion A2 is installed on the driven side of the external device.

[0031] The first steering portion A1 and the second steering portion A2 each include a first housing 1, with two sets of sliding grooves 101 defined within the first housing 1. A first rotating groove 102 is defined at the symmetrical center between the two sets of sliding grooves 101. Sliding rods 104 are slidably mounted within the two sets of sliding grooves 101. A toothed disc 103 is rotatably mounted within the first rotating groove 102 for engaging with the two sets of sliding rods 104. Two sets of first interfaces 105 are defined on one side of the first housing 1, respectively communicating with the two sets of sliding grooves 101. An external connection disc 106 for connecting to an external rudder or engine is defined on one side of the toothed disc 103. The sliding grooves 101 and the pipeline 3 are filled with a liquid for transmission.

[0032] Based on the above content, two groups of pipelines 3 should be provided, and the two groups of pipelines 3 are used for communication between the two groups of first interfaces 105 on the first turning part A1 and the second turning part A2, respectively. Figure 1 、 4 When the toothed disc 103 in the first steering part A1 is rotated, the two sets of sliding rods 104 on both sides of the toothed disc 103 move in opposite directions. At this time, the sliding rods 104 push the sliding groove 101 and the liquid in the pipeline 3 to move forward, thereby driving the sliding rods 104 in the second steering part A2 to move forward. The sliding rods 104 in the second steering part A2 engage with the toothed disc 103 to achieve the effect of hydraulic steering transmission;

[0033] Furthermore, both ends of the sliding rod 104 are sleeved with sealing rings 1041 that can slide against the inner wall of the sliding groove 101. The sealing rings 1041 should be made of oil-resistant material so that oily liquid can be injected into the sliding groove 101 and the pipeline 3 to achieve transmission and prevent the sealing rings 1041 from being corroded.

[0034] For further reference, Figure 4 The sliding groove 101 can be opened in the left and right sides of the first shell 1, and sealing covers are sealed and installed on both sides of the first shell 1 by bolts or the like, so as to facilitate the removal of the sliding rod 104 from the sliding groove 101 for maintenance;

[0035] Furthermore, to ensure smooth liquid flow and compatibility with different liquids, the inner diameter of the first interface 105 and the pipeline 3 should be greater than 5 mm;

[0036] For further reference, Figure 4 , a connecting groove may be opened between the tail ends of the two sets of sliding grooves 101 to maintain the hydraulic balance on both sides of the sliding grooves 101;

[0037] Furthermore, the front end of one set of sliding grooves 101 is connected to the rear end of the other set of sliding grooves 101 through a connecting groove;

[0038] For further reference, Figure 1The first steering portion A1 and the second steering portion A2 are oriented in opposite directions to ensure that the rotation direction of the active side is consistent with the rotation direction of the driven side.

[0039] Reference Figure 1 、 2 3. Here is an example of how the return system is implemented:

[0040] A return system is connected between the first steering portion A1 and the second steering portion A2 via a pipeline 3. The return system includes a second housing 2. Two sets of first passages 201 are formed inside the second housing 2. A second passage 202 is connected between the two sets of first passages 201. A rotary valve 204 is rotatably installed inside the second passage 202 to serve as an on / off switch. Both ends of the two sets of first passages 201 are connected to a second port 203. All four sets of second ports 203 are connected to the first port 105 via a pipeline 3.

[0041] Based on the above, refer to Figure 1 、 3 When the rotary valve 204 is closed, the second passage 202 is closed. At this time, the two ends of the first passage 201 are directly connected, which has the same function as the pipeline 3. When the rotary valve 204 is opened, the second passage 202 is connected. At this time, the two sets of second interfaces 203 located on the same side are connected. When the toothed disc 103 in the first steering part A1 or the second steering part A2 is rotated, the liquid self-circulates through the second passage 202 to achieve angle correction of the external disc 106 connected to the toothed disc 103. That is, when the rotary valve 204 is opened and the second passage 202 is connected, the first steering part A1 and the second steering part A2 will not drive synchronously, achieving independent correction.

[0042] Furthermore, regulating valves 205 are provided inside the two sets of second interfaces 203 on one side of the second housing 2. The regulating valves 205 are used to close the second interfaces 203. This function can be used when the rotary valve 204 is open to achieve an independent locking effect.

[0043] Furthermore, the return system should be designed close to one side of the first turning portion A1 or the second turning portion A2 to be calibrated, so that the liquid inside the calibrated first turning portion A1 or the second turning portion A2 is preferentially conducted through the second passage 202 .

[0044] Reference Figure 5 Here is an example of a kart boat using the above hydraulic steering system:

[0045] A go-kart includes a rudder and an engine. An external plate 106 in a first steering portion A1 is connected to the rudder via bolts or other structures. An external plate in a second steering portion A2 is connected to a housing at the upper end of the engine via a gear set or other structures. When the rudder is turned, the hydraulic steering system synchronizes the engine, thereby controlling the steering of the go-kart. In this case, the first steering portion A1 is the active side, and the second steering portion A2 is the driven side.

[0046] Furthermore, the return system should be installed close to the first steering portion A1, and the second steering portion A2 is used to drive the engine to rotate along its own central axis to achieve the deflection of the blade angle on the engine output shaft.

[0047] Based on the examples of the above implementations, during installation:

[0048] Connect the external plate 106 in the first steering part A1 to the bottom of the rudder through bolts and other structures, connect the external plate 106 in the second steering part A2 to the upper end of the engine housing through bolts and other structures, and install the return system on the side close to the first steering part A1, as shown in the figure. Figure 5 As shown, the return system can be directly installed in the ship's operating console.

[0049] Based on the above implementation examples, when used:

[0050] The steering rudder is rotated, and the rudder drives the external disc 106 and the gear disc 103 in the first steering part A1 to rotate. The gear disc 103 engages with the two sets of sliding rods 104, and the sliding rods 104 extract or squeeze the liquid in the sliding groove 101. At this time, the liquid is transmitted to the second steering part A2 through the pipeline 3, and drives the two sets of sliding rods 104 in the second steering part A2 to produce follower, thus achieving a transmission effect.

[0051] When the rotary valve 204 is opened, the two groups of first passages 201 are connected through the second passage 202. At this time, the liquid in the pipeline 3 will be preferentially returned through the second passage 202 to achieve a calibration function.

[0052] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
