[0081] The terms "parallel" / "perpendicular" and similar expressions used in this application include an absolute parallel / perpendicular relationship and a roughly parallel / perpendicular relationship (for example, a relationship that differs from absolute parallel / perpendicular by a range of -5° to +5°), which can have equivalent effects.

[0082] Hereinafter, specific embodiments of the present application will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present application and do not limit the present application.

[0083] like Figures 1 to 4 As shown, the present application provides a hydraulic torque conversion device 100, a steering assembly 10 and a vehicle (not shown). The steering assembly 10 includes a hydraulic torque conversion device 100. The hydraulic torque conversion device 100 includes a steering assembly 10. The hydraulic torque conversion device 100, the steering assembly 10 and the vehicle according to the present application will be described in detail below with reference to the accompanying drawings.

[0084] See also Figures 1 to 4 The present application provides a hydraulic torque conversion device 100. The hydraulic torque conversion device 100 may include a first hydraulic transmission component 101, a second hydraulic transmission component 102, and a pipeline. The first hydraulic transmission component 101 is suitable for connecting to a steering column 150 to convert the torque of the steering column 150 into hydraulic force. The steering column 150 is used to install a steering wheel (not shown). The second hydraulic transmission component 102 is suitable for connecting to a steering gear 160 to convert hydraulic force into the torque of the steering gear 160. The pipeline is connected to the first hydraulic transmission component 101 and the second hydraulic transmission component 102 to transmit hydraulic force in the first hydraulic transmission component 101 and the second hydraulic transmission component 102.

[0085] According to the hydraulic torque conversion device of the present application, the first hydraulic transmission component 101 can convert torque into hydraulic force and transmit it to the second hydraulic transmission component 102 via the pipeline, and the second hydraulic transmission component 102 can receive the hydraulic force transmitted via the pipeline and convert the hydraulic force into torque. When the first hydraulic transmission component 101 is connected to the steering column 150 and the second hydraulic transmission component 102 is connected to the steering gear 160, the torque is transmitted between the steering column 150 and the steering gear 160 in the form of torque-hydraulic-torque transmission through the first hydraulic transmission component 101, the pipeline and the second hydraulic transmission component 102. On the one hand, this helps to achieve a non-rigid connection between the steering gear 160 and the steering column 150, and can effectively filter the vibration transmitted from the road surface to the steering wheel; on the other hand, it can provide more collapse space for the steering wheel and is conducive to the layout of a larger front powertrain.

[0086] See also Figure 3 and Figure 4 For example, the first hydraulic transmission component 101 and the second hydraulic transmission component 102 may each include a housing 111, a partition 112, a fan blade 113, and a transmission shaft 114. The housing 111 includes a hydraulic chamber 111a centered on the first axis AX1. The housing 111 is provided with a first hole 111b and a second hole 111c. The first hole 111b and the second hole 111c are arranged at intervals. The partition 112 is fixed to the hydraulic chamber 111a. The partition 112 is configured to extend radially from the first axis AX1 to between the first hole 111b and the second hole 111c. The radial direction is perpendicular to the first axis AX1. The radial direction here is the radial direction of a circle centered on the first axis AX1. The fan blade 113 is rotatably connected to the hydraulic chamber 111a around the first axis AX1. The fan blade 113 is configured to extend radially from the first axis AX1 perpendicular to the first axis AX1. The fan blades 113 and the partition 112 together divide the hydraulic chamber 111a into a first chamber 110a and a second chamber 110b. The first chamber 110a is connected to the outside of the housing 111 via the first hole 111b to transmit hydraulic force. The second chamber 110b is connected to the outside of the housing 111 via the second hole 111c to transmit hydraulic force. The transmission shaft 114 is rotatably connected to the housing 111 around its own axis. The transmission shaft 114 is transmission-connected to the fan blades 113 to rotate synchronously with the fan blades 113. The transmission shaft 114 is used to transmit torque.

[0087] The principle of the conversion from torque to hydraulic force of the first hydraulic transmission component 101 and the second hydraulic transmission component 102 is as follows: during the rotation of the transmission shaft 114, the fan blade 113 rotates accordingly, thereby changing the volume of the first chamber 110a and the volume of the second chamber 110b. While one of the volumes of the first chamber 110a and the second chamber 110b increases, the other of the volumes of the first chamber 110a and the second chamber 110b decreases, thereby outputting liquid through one of the first hole 111b and the second hole 111c, and receiving liquid through the other of the first hole 111b and the second hole 111c. In this way, the conversion from torque to hydraulic force is achieved.

[0088] The principle of the conversion from hydraulic force to torque of the first hydraulic transmission component 101 and the second hydraulic transmission component 102 is as follows: when one of the first hole 111b and the second hole 111c outputs liquid and the other of the first hole 111b and the second hole 111c receives liquid, one of the volume of the first chamber 110a and the volume of the second chamber 110b increases, and the other of the volume of the first chamber 110a and the volume of the second chamber 110b decreases, so that the fan blade 113 rotates around the first axis AX1, and then drives the transmission shaft 114 to rotate around the first axis AX1. In this way, the conversion from hydraulic force to torque is achieved.

[0089] See also Figure 4 Optionally, the axis of the transmission shaft 114 coincides with the first axis AX1. In other examples, the axis of the transmission shaft 114 is parallel to or intersects with the first axis AX1. The following mainly describes an example in which the axis of the transmission shaft 114 coincides with the first axis AX1.

[0090] See also Figure 4 , further, the transmission shaft 114 of the first hydraulic transmission assembly 101 is suitable for connecting to the steering column 150. Optionally, the transmission shaft 114 of the first hydraulic transmission assembly 101 is suitable for connecting to the output shaft 151 of the steering column 150, so as to receive the torque of the output shaft 151 and convert it into hydraulic force in the pipeline for transmission. The transmission shaft 114 of the second hydraulic transmission assembly 102 is suitable for connecting to the steering gear 160. Optionally, the transmission shaft 114 of the second hydraulic transmission assembly 102 is suitable for connecting to the input shaft 161 of the steering gear 160, so as to receive the hydraulic force transmitted by the pipeline and convert the hydraulic force into torque and transmit it to the input shaft 161.

[0091] When the drive shaft 114 of the first hydraulic transmission component 101 is connected to the output shaft 151 of the steering column 150, and the drive shaft 114 of the second hydraulic transmission component 102 is connected to the input shaft 161 of the steering gear 160, the user turns the steering wheel to generate torque on the steering column 150. The torque of the steering column 150 is converted into hydraulic force via the first hydraulic transmission component 101, and then the hydraulic force is transmitted to the second hydraulic transmission component 102 via the liquid in the pipeline. The second hydraulic transmission component 102 converts the hydraulic force into the torque of its drive shaft 114 and transmits it to the input shaft 161 of the steering gear 160, thereby driving the steering gear 160 to operate and finally driving the wheels to steer.

[0092] See also Figures 1 to 4 For example, the above-mentioned pipeline can be referred to as a hydraulic pipeline, an oil pipeline, a hydraulic oil pipeline or a hydraulic pipeline. The pipeline may include a first pipeline 103 and a second pipeline 104. One end of the first pipeline 103 is connected to one of the first hole 111b and the second hole 111c of the first hydraulic transmission component 101. The other end of the first pipeline 103 is connected to one of the first hole 111b and the second hole 111c of the second hydraulic transmission component 102. One end of the second pipeline 104 is connected to the other of the first hole 111b and the second hole 111c of the first hydraulic transmission component 101. The other end of the second pipeline 104 is connected to the other of the first hole 111b and the second hole 111c of the second hydraulic transmission component 102. In this way, the first chamber 110a and the second chamber 110b of the first hydraulic transmission component 101 can be connected to the first chamber 110a and the second chamber 110b of the second hydraulic transmission component 102 respectively, so that liquid can flow between the first hydraulic transmission component 101 and the second hydraulic transmission component 102, and then the hydraulic force can be transmitted between the first hydraulic transmission component 101 and the second hydraulic transmission component 102.

[0093] See also Figure 3 Optionally, the first pipeline 103 is connected to the first hole 111b of the first hydraulic transmission component 101 and the first hole 111b of the second hydraulic transmission component 102 to be connected to the first cavity 110a. Correspondingly, the second pipeline 104 is connected to the second hole 111c of the first hydraulic transmission component 101 and the second hole 111c of the second hydraulic transmission component 102 to be connected to the second cavity 110b.

[0094] Exemplarily, liquid such as hydraulic oil flows through the above-mentioned pipelines, the first pipeline 103 and the second pipeline 104 .

[0095] See also Figure 1 and Figure 2In addition, the hydraulic torque conversion device 100 may further include a reversing valve 105. The reversing valve 105 is connected in series to the first pipeline 103 and the second pipeline 104. By setting the reversing valve 105, the direction in which the liquid is allowed to flow can be adjusted according to the direction of the liquid in the pipeline. The reversing valve 105 usually performs a reversing action when the direction in which the steering wheel is turned changes. Here, the direction in which the steering wheel is turned changes, for example, from being turned in a clockwise direction to being turned in a counterclockwise direction.

[0096] See also Figure 4 In addition, the hydraulic torque conversion device according to the embodiment of the present application may further include a speed change gear train component 116. The first hydraulic transmission assembly 101 and the second hydraulic transmission assembly 102 each include a speed change gear train component 116. The speed change gear train component 116 is transmission-connected to the transmission shaft 114 and the fan blades 113 so that the rotation speed of the transmission shaft 114 is different from the rotation speed of the fan blades 113.

[0097] Generally, the magnitude of the steering wheel rotation angle is positively correlated with the magnitude of the wheel steering angle, and at the same time, the steering wheel rotation angle is generally smaller than the wheel steering angle. In general, the rotation speed of the transmission shaft 114 of the first hydraulic transmission assembly 101 is smaller than the rotation speed of the transmission shaft 114 of the second hydraulic transmission assembly 102. For the first hydraulic transmission assembly 101, the rotation speed of the transmission shaft 114 may be, for example, smaller than the rotation speed of the blades 113. Accordingly, for the second hydraulic transmission assembly 102, the rotation speed of the blades 113 may be, for example, smaller than the rotation speed of the transmission shaft 114.

[0098] In other examples, the rotation speed of the transmission shaft 114 of the first hydraulic transmission assembly 101 is less than the rotation speed of the transmission shaft 114 of the second hydraulic transmission assembly 102. For the first hydraulic transmission assembly 101, the rotation speed of the transmission shaft 114 may be, for example, greater than the rotation speed of the blades 113. For the second hydraulic transmission assembly 102, the rotation speed of the blades 113 may be, for example, less than the rotation speed of the transmission shaft 114.

[0099] In other examples, the rotation speed of the transmission shaft 114 of the first hydraulic transmission assembly 101 is less than the rotation speed of the transmission shaft 114 of the second hydraulic transmission assembly 102. For the first hydraulic transmission assembly 101, the rotation speed of the transmission shaft 114 may be, for example, less than the rotation speed of the blades 113. For the second hydraulic transmission assembly 102, the rotation speed of the blades 113 may be, for example, greater than the rotation speed of the transmission shaft 114.

[0100] In other examples, the rotation speed of the transmission shaft 114 of the first hydraulic transmission assembly 101 is equal to or greater than the rotation speed of the transmission shaft 114 of the second hydraulic transmission assembly 102 .

[0101] See also Figure 4For example, the speed change gear train component 116 may include a first gear 117, a second gear 118, a third gear 119, and a fourth gear 121. The first gear 117 is coaxially fixed to the fan blade 113. The second gear 118 is coaxially fixed to the transmission shaft 114. The number of teeth of the second gear 118 is different from the number of teeth of the first gear 117. This makes the rotation speed of the fan blade 113 different from the rotation speed of the transmission shaft 114. The third gear 119 is rotatably connected to the housing 111 around the second axis AX2. The third gear 119 is meshed with the first gear 117. The second axis AX2 coincides with the axis of the third gear 119 and is parallel to the first axis AX1. The fourth gear 121 is coaxially fixed to the third gear 119. The fourth gear 121 is meshed with the second gear 118.

[0102] like Figure 4 As shown, further, the first hydraulic transmission component 101 and the second hydraulic transmission component 102 can each also include a rotating shaft 115. The rotating shaft 115 is rotatably connected to the housing 111 around its own axis. At least part of the rotating shaft 115 is located in the hydraulic chamber 111a and fixed to the fan blade 113. The rotating shaft 115 is fixed to the first gear 117. The axis of the rotating shaft 115 coincides with the first axis AX1. Correspondingly, the transmission shaft 114 is connected to the second gear 118. And part of the transmission shaft 114 is located outside the housing 111 for connecting to the output shaft 151 of the steering column 150 or the input shaft of the steering gear 160. In this embodiment, the rotating shaft 115 is coaxial with the transmission shaft 114 and is arranged at intervals.

[0103] exist Figure 4 In the illustrated embodiment, the housing 111 includes a peripheral side wall 111f, a first end wall 111g, and a second end wall 111h. The peripheral side wall 111f is configured as a solid wall having a circular cross section centered on the first axis AX1. The first end wall 111g and the second end wall 111h are arranged opposite to each other in an axial direction D2 parallel to the first axis AX1. Figure 4In the embodiment, the first end wall 111g is located on the left side of the second end wall 111h. One end of the axial direction D2 of the peripheral side wall 111f protrudes from the second end wall 111h to enclose with the second end wall 111h to form a mounting groove 111k. The first support member 111i and the second support member 111j are arranged in sequence and spaced apart in the axial direction D2. The second end wall 111h, the first support member 111i and the peripheral side wall 111f enclose a first accommodating chamber 111d. The first accommodating chamber 111d accommodates the above-mentioned first gear 117 and the third gear 119. The first support member 111i, the second support member 111j and the peripheral side wall 111f enclose a second accommodating chamber 111e.

The first accommodating cavity 111d is provided to accommodate the first gear 117 and the third gear 119, and the second accommodating cavity 111e is provided to accommodate the second gear 118 and the fourth gear 121, so that separate maintenance is facilitated and interference between gears located at different positions in the axial direction D2 can be prevented.

[0104] Optionally, the peripheral side wall 111f protrudes from the second support member 111j in the axial direction D2. The transmission shaft 114 is at least partially located in the mounting groove 111k.

[0105] Exemplarily, the housing 111 includes the first support member 111i and the second support member 111j.

[0106] See also Figure 4 In addition, the first hydraulic transmission assembly 101 and the second hydraulic transmission assembly 102 may each further include a connecting shaft 122. The connecting shaft 122 is rotatably connected to the housing 111 around its own axis. The connecting shaft 122 is fixed to the third gear 119 and the fourth gear 121. The axis of the connecting shaft 122 coincides with the second axis AX2. Figure 4 As can be seen in the figure, the connecting shaft 122 passes through the first support member 111i. One end of the connecting shaft 122 extends into the first accommodating cavity 111d to be connected to the third gear 119. The other end of the connecting shaft 122 extends into the second accommodating cavity 111e to be connected to the fourth gear 121.

[0107] Optionally, one end of the rotating shaft 115 extends into the first accommodating cavity 111 d to be connected to the first gear 117 . One end of the transmission shaft 114 extends into the second accommodating cavity 111 e to be connected to the second gear 118 .

[0108] See also Figure 4For example, at least two sets of the third gear 119 and the fourth gear 121 are provided respectively. And each set of the third gear 119 and the fourth gear 121 is arranged at intervals in the circumferential direction of the first gear 117. In this way, the force balance of each part of the circumferential direction of the first gear 117 and the second gear 118 can be improved, thereby improving the stability of the speed change gear train assembly.

[0109] Optionally, a plurality of third gears 119 are provided, and the plurality of third gears 119 are arranged at intervals in the circumferential direction of the first gear 117. Further optionally, the plurality of third gears 119 are arranged at equal intervals in the circumferential direction of the first gear 117.

[0110] Optionally, a plurality of fourth gears 121 are provided, and the plurality of fourth gears 121 are arranged at intervals in the circumferential direction of the second gear 118. Further optionally, the plurality of fourth gears 121 are arranged at equal intervals in the circumferential direction of the second gear 118.

[0111] Optionally, the first hydraulic transmission assembly 101 and the second hydraulic transmission assembly 102 using the above technical means can each be called a hydraulic fan. The hydraulic fan can be replaced by a hydraulic torque conversion structure such as a spiral worm structure, a hydraulic linear transmission structure, etc.

[0112] According to the hydraulic torque conversion device 100 of the present application, in terms of realizing the steering function, compared with the traditional mechanical linkage steering or wire-controlled steering, while ensuring the reliability of the steering function, it provides higher safety and position controllability. At the same time, the hydraulic fan structure such as the first hydraulic transmission component 101 and the second hydraulic transmission component 102 mentioned above also facilitates the modular development of the vehicle. With the acceleration of the modularization process of new energy vehicles, the present application will also be widely used.

[0113] See also Figure 1 and Figure 2 The embodiment of the present application further provides a steering assembly 10. The steering assembly 10 may include a steering column 150, a steering gear 160, and the above-mentioned hydraulic torque conversion device 100. The transmission shaft 114 of the first hydraulic transmission component 101 is connected to the steering column 150. The transmission shaft 114 of the second hydraulic transmission component 102 is connected to the steering gear 160.

[0114] According to the steering assembly of the present application, by applying the above-mentioned hydraulic torque conversion device, the first hydraulic transmission component 101 is connected to the steering column 150, and the second hydraulic transmission component 102 is connected to the steering gear 160. The steering column 150 transmits torque to the steering gear 160 through the first hydraulic transmission component 101, the pipeline and the second hydraulic transmission component 102. The first hydraulic transmission component 101 and the second hydraulic transmission component 102 are in the form of hydraulic transmission, and are not rigidly connected. This helps to realize that the steering gear 160 and the steering column 150 are no longer rigidly connected, and can effectively filter the vibration transmitted from the road to the steering wheel; on the other hand, it can provide more collapse space for the steering wheel and is conducive to the layout of a larger front powertrain.

[0115] See also Figure 2 In addition, the steering assembly 10 may further include a bearing member 141 and a movable member 142. The bearing member 141 is adapted to be fixed to the vehicle body. The movable member 142 is movably connected to the bearing member 141 in the extension direction D1 of the bearing member 141. The movable member 142 is connected to the steering column 150 to change the position of the steering column 150. When the bearing member 141 is mounted to the vehicle body, the extension direction D1 of the bearing member 141 is the vehicle width direction. By adopting this technical means, the position of the movable member 142 in the width direction of the vehicle body can be changed as needed, so that the installation position of the steering column 150 in the width direction of the vehicle body can be changed. Thus, it is helpful to change the installation position of the steering wheel as needed to adapt to the corresponding steering position requirements. The steering position here refers to the driving position or the position of the steering wheel. The steering position requirements here may be, for example, the requirement to drive in the left steering position, the requirement to drive in the middle steering position, or the requirement to drive in the right steering position, etc.

[0116] Alternatively, the steering column 150 may be indirectly mounted to the movable member 142 via the bracket 143. The bracket 143 may be fixed to the steering column 150 and the movable member 142 by welding, fastener connection, or the like.

[0117] In an optional example, the supporting member 141 and the movable member 142 may be connected via a guide rail slider assembly so as to more smoothly adjust the position of the movable member 142 in the extension direction D1, which also helps to improve the accuracy of position adjustment.

[0118] Further optionally, a lead screw nut assembly can be provided between the bearing member 141 and the movable member 142, and the lead screw of the lead screw nut assembly is connected to a power source such as a motor. When the motor outputs power, the movable member 142 can be driven to move relative to the bearing member 141 in the extension direction D1. In other examples, the lead screw nut assembly can also be replaced by a transmission assembly such as a gear rack assembly. The combination of the lead screw nut assembly and the power source can also be replaced by a drive assembly such as a linear motor, a servo motor and a track combination structure.

[0119] In another optional example, the bearing member 141 and the movable member 142 can be connected in a detachable manner by snap connection, fasteners, etc. Here, a brief description is given by taking the bearing member 141 and the movable member 142 connected by fasteners as an example. The bearing member 141 is provided with a plurality of mounting holes suitable for connecting fasteners. The plurality of mounting holes are arranged at intervals in the extension direction D1. By mounting the movable member 142 to different mounting holes by fasteners, it is possible to change the position of the movable member 142 in the extension direction D1 of the bearing member 141, thereby changing the installation position of the steering column 150 in the extension direction D1.

[0120] like Figure 2 As shown, in addition, the steering assembly 10 may further include a locking and unlocking member 180. The locking and unlocking member 180 is connected to at least one of the carrier 141 and the movable member 142. The locking and unlocking member 180 has a locked state and an unlocked state. The locking and unlocking member 180 in the locked state prevents the movable member 142 from moving relative to the carrier 141. The locking and unlocking member 180 in the unlocked state allows the movable member 142 to move relative to the carrier 141. By providing the locking and unlocking member 180, it is convenient to unlock and lock the movable member 142 as needed, thereby facilitating the adjustment of the position of the movable member 142 as needed, and locking the position of the movable member 142 as needed.

[0121] Optionally, the locking and unlocking member 180 may adopt any existing structure capable of achieving locking and unlocking functions, such as a snap connection structure.

[0122] See also Figure 1 and Figure 2 In addition, the steering assembly 10 may further include a pipeline collector 190. The pipeline collector 190 is connected to the pipeline to store and release the pipeline. In order to meet the needs of position adjustment of the steering column 150, the pipeline is usually configured to be long enough. When the steering column 150 changes its position in the extension direction D1 of the support member 141, that is, the width direction of the vehicle body, the pipeline may become loose. In order to prevent the pipeline from interfering with the adjacent structure due to shaking, the pipeline collector 190 can reliably store the pipeline so that the pipeline can be kept in a moderate tension state. After the pipeline collector 190 releases the pipeline from the appropriate storage box, it is also more convenient to organize and fix the remaining pipelines, which can improve the rationality and reliability of the pipeline layout.

[0123] Continue reading Figure 1 and Figure 2 Furthermore, the steering assembly 10 may further include a pipe laying member 130. The pipe laying member 130 is used to be fixed to the vehicle body to lay and support the pipeline. Figure 1 and Figure 2In the example shown, the steering gear 160 is located on the right side of the figure. When the position of the steering column 150 is adjusted to the left side of the figure, the steering column 150 and the steering gear 160 are spaced apart or at least partially staggered in the extension direction D1 of the bearing member 141. At this time, the length of the pipeline between the steering column 150 and the steering gear 160 is relatively long, and part of the pipeline can be supported by the pipe 130. Further optionally, the pipeline can be constrained on the pipe 130 by a constraint such as a cable tie to prevent the pipeline from moving relative to the pipe 130.

[0124] Optionally, the pipe-laying member 130 may be constructed as a plate or a frame. In addition to extending along the extension direction D1 as a whole, the end of the pipe-laying member 130 in the extension direction D1 may be constructed as a transition portion that is bent, curved or inclined upward, so as to make a smoother transition of the direction of the pipeline in the extension direction D1 and the up-down direction, and also help to increase the contact area between the pipeline and the pipe-laying member 130, so that the pipeline is supported more stably by the pipe-laying member 130.

[0125] See also Figure 1 and Figure 2 In addition, the steering assembly 10 may further include a steering tie rod 170. The steering tie rod 170 is connected to the output shaft of the steering gear 160. The steering tie rod 170 is used to drive the wheels to steer under the output torque of the steering gear 160.

[0126] According to the steering assembly of the embodiment of the present application, the first hydraulic transmission component 101 installed at the lower end of the steering column 150 and the second hydraulic transmission component 102 located at the upper end of the steering gear 160 are linked through hydraulic pipelines. When turning, the rotation of the steering wheel drives the first hydraulic transmission component 101 to transmit the hydraulic oil force to the second hydraulic transmission component 102, and the second hydraulic transmission component 102 drives the rack movement of the steering gear 160 to achieve steering. The beneficial technical effects of the present application include:

[0127] (1) Since the steering gear 160 and the steering column 150 are not fixedly connected by a rigid mechanical structure, the position switch of the steering column 150 between the left, right and center steering in the vehicle can be realized by designing a sliding or transmission structure at the mounting structure of the steering column 150 and the vehicle body. This makes it easy for the driver to adjust the steering wheel position according to his or her preferences. Alternatively, when designing and assembling, only the mounting position of the steering column 150 and the steering wheel needs to be adjusted to easily realize the switching of the assembly position of the left and right steering, which can reduce the types of steering gears for forward or backward reversing, increase interchangeability and versatility, and reduce vehicle costs.

[0128] (2) Since the steering gear 160 and the steering column 150 are not fixedly connected, it is advantageous to arrange a larger powertrain or functional device on the front suspension of the vehicle, making the vehicle more functional and providing a larger steering wheel crumple space when the vehicle collides, making the collision safer.

[0129] (3) Because the steering gear 160 and the steering column 150 are connected by a hydraulic pipeline, the problem of road vibration being easily transmitted to the steering wheel through the steering structure in a direct connection is avoided, thereby improving driving comfort. Although traditional wire-controlled steering can also achieve this vibration filtering function, regulations have many safety redundancy requirements for wire-controlled steering, resulting in high difficulty in implementing wire-controlled steering. The present application uses hydraulic transmission, which has higher reliability, safety and stability, better regulatory adaptability (compared to the redundant safety requirements of wire-controlled steering), and has the spatial layout advantage of wire-controlled steering. This structure has higher steering gear versatility, can optimize steering gear types, and reduce costs.

[0130] (4) The present application uses hydraulic transmission to facilitate the layout of hydraulic pipelines. In some application scenarios, the driver's seat can be designed in the back row, and the vehicle can be driven with panoramic imaging, which can provide more collision and crumple space in front of the vehicle and improve the rear-end collision safety of the front of the vehicle.

[0131] In summary, in the steering assembly, hydraulic steering makes the steering gear 160 and the steering column 150 no longer rigidly connected, which can effectively filter the vibration transmitted from the road surface to the steering wheel, while providing more collapse space for the steering wheel, and is conducive to the layout of a larger front powertrain. By adjusting the layout of the hydraulic pipeline, it is possible to easily switch the positions of the left, center, and right rudders, and even with the panoramic image, steering in the rear rudder can be better achieved. Compared with the traditional mechanical linkage steering assembly, the hydraulic steering structure adopted in this application can improve the comfort, safety, and interchangeability of steering, reduce the limitations of the structural layout of the steering assembly, and enable the steering position of the same vehicle to meet the needs of different sales areas for left and right rudder steering applications, thereby improving the convenience and flexibility of market sales and enriching the use scenarios of the steering assembly.

[0132] See also Figures 1 to 4 The embodiment of the present application further provides a vehicle. The vehicle may include the steering assembly 10 according to the above.

[0133] According to the vehicle of the present application, by applying the above-mentioned steering assembly, on the one hand, it is possible to effectively filter the vibration transmitted from the road surface to the steering wheel; on the other hand, it is possible to provide more crumple space for the steering wheel and facilitate the layout of a larger front powertrain.

[0134] For example, the steering column 150 can be selectively installed in one of the left steering position and the right steering position of the vehicle. The left steering position and the right steering position are at both ends of the width direction of the vehicle. The left steering position here can be understood as when the driver is in the vehicle and faces the front of the vehicle, the steering wheel and the main driving position are set at the left end of the vehicle. Correspondingly, the right steering position can be understood as when the driver is in the vehicle and faces the front of the vehicle, the steering wheel and the main driving position are set at the right end of the vehicle.

[0135] For example, the vehicle may include the above-mentioned bearing member 141 and movable member 142. The bearing member 141 extends in the width direction of the vehicle. The movable member 142 is movably connected to the bearing member 141 in the width direction. The steering column 150 is connected to the movable member 142 to change position in the width direction with the movable member 142. Optionally, the bearing member 141 may be fixed to the vehicle body frame or configured as a part of the vehicle body frame.

[0136] The vehicle of the embodiment of the present application adopts a hydraulic torque conversion device to realize the conversion of torque-hydraulic-torque, that is, the steering column and the steering gear realize torque transmission through hydraulic force. Compared with the mechanical linkage type used in the related art to realize torque transmission between the steering column and the steering gear, it can better filter the vibration from the road surface, thereby improving comfort. At the same time, it can provide more collapse space for the steering column and the steering wheel, thereby improving collision safety. Since the first hydraulic transmission component and the second hydraulic transmission component are connected by pipelines, compared with the rigid connection structure, the pipeline can better adapt to a smaller assembly space, thereby reducing space occupation, and then providing more space for the chassis layout of the whole vehicle. Furthermore, by setting components such as bearing parts, movable parts, locking and unlocking parts, and pipeline collectors, the steering wheel and the steering column can be switched between the left, middle, and right rudder positions in the vehicle, thereby meeting the needs of different countries and regions for the use of left and right rudders, and increasing the versatility of the vehicle.
