As shown in fig. 2, the steering system 200 of this embodiment may include a steering wheel device 210 and a steering drive device 220. The steering drive 220 may include, for example, a motor assembly and a transmission rod, and is fixedly connected to the steering wheel unit 210 via the transmission rod. In particular, the transmission rod can be connected to a wheel hub in the steered wheel arrangement via a connecting assembly. Therefore, the transmission rod can transmit the power provided by the motor assembly to the hub and drive the hub to change the rotating direction, and the steering wheel sleeved on the hub changes the rotating direction under the driving of the hub, so that the driving direction of the vehicle comprising the steering system 200 is changed.

In an embodiment, the steering system 200 may include two steering wheel devices, and the steering driving device 220 may include two transmission rods to be fixedly connected with the two steering wheel devices 210 via the two transmission rods, respectively.

In one embodiment, the steering drive 220 may further include a steering gear including an input and two outputs. The input end of the steering gear is connected with the output shaft of the motor assembly, and the two output ends of the steering gear are respectively hinged with the two transmission rods.

The steering gear can adopt a gear rack structure, a circulating ball structure, a worm-crank pin type structure, a power steering gear and other structures in various forms, and the disclosure does not limit the structures.

The steering wheel device included in the steering system provided by the present disclosure will be described in detail below with reference to fig. 3 to 8.

Fig. 3 is a schematic structural view of a steerable wheel apparatus according to an embodiment of the present disclosure.

As shown in fig. 3, the steering wheel device 310 of this embodiment may include a wheel suspension assembly 311, a connecting assembly 312, and a steering wheel assembly 313.

The wheel suspension assembly 311 may include a mounting bracket, an elastic member, a first guide post, a fixing block, and the like. The wheel suspension assembly may take the configuration described below and will not be described in detail herein.

The connecting assembly 312 is used to connect the wheel suspension assembly 311 and the steering wheel assembly 313 in an articulated manner, so that the steering wheel assembly 313 can rotate relative to the wheel suspension assembly 311, and the elastic member in the wheel suspension assembly 311 can be compressed or stretched under the driving of the steering wheel assembly 313. For example, the connection assembly 312 may be fixedly connected to an elastic member in the wheel suspension assembly 311 to transmit a vertical force applied to the connection assembly when the steering wheel assembly 313 moves up and down to the elastic member.

The steering wheel assembly 313 may include a steering wheel and a wheel hub, the steering wheel is sleeved on the wheel hub, and the connecting assembly may be rotatably connected to the steering wheel assembly via the wheel hub, so as to connect the wheel suspension assembly and the steering wheel assembly.

In one embodiment, the connecting assembly can also be fixedly connected with the steering drive, for example, to provide the steering force provided by the steering drive to the steered wheel arrangement, so that the steered wheel arrangement changes the direction of rotation.

Fig. 4 is an exploded view of a connection assembly according to an embodiment of the present disclosure.

As shown in fig. 4, in one embodiment, the connection assembly 412 may include a support member 4121, a rotating shaft 4122, and a corner piece 4123. The supporting member 4121 is fixedly connected to the elastic member of the wheel suspension assembly, the rotating shaft 4122 is fixedly connected to the supporting member 4121, the angle joint 4123 is sleeved on the rotating shaft 4122 and rotatably connected to the steering wheel device, and the angle joint 4123 can rotate around the central axis of the rotating shaft 4122 under an external force. In this manner, the steerable wheel unit can rotate relative to the corner piece 4123 and can provide a vertical force to the corner piece 4123 during jounce, which force can be transmitted to the resilient member in the wheel suspension assembly via the rotating shaft 4122 and the support member 4121, thereby causing the resilient member to be compressed or stretched. For example, the angle member 4123 may be fixedly connected to the steering driving device, so that the angle member 4123 may rotate about the central axis of the rotating shaft 4122 by the steering force provided by the steering driving device and provide a force perpendicular to the rotating direction to the steering wheel device, thereby changing the rotating direction of the steering wheel device.

In one embodiment, as shown in fig. 4, the support member 4121 may include a support plate 41211 and two fixing plates 41212. Wherein the supporting plate 41211 is fixedly connected with the elastic member. The two retaining plates 41212 may extend in a direction perpendicular to the support plate 41211, and the two retaining plates 41212 may be located on the same side of the support plate 41211 as the corner pieces 4123, for example.

In one embodiment, the two fixing plates 41212 may be provided with fixing holes, and the rotating shaft 4122 may be engaged in the fixing holes of the two fixing plates. For example, the rotating shaft 4122 is a rod-shaped structure, and both ends of the rod-shaped structure may be provided with external threads. The rotating shaft 4122 may be inserted into the fixing holes of the two fixing plates, and then the rotating shaft 4122 and the supporting member 4121 may be fixedly connected through the engagement between the fixing members such as nuts and the external threads at the two ends of the rotating shaft 4122.

For example, the rotating shaft 4122 may be a cylindrical structure having external threads at both ends thereof so that a corner fitting may rotate about a central axis of the rotating shaft 4122.

In one embodiment, when the corner piece 4123 is sleeved on the rotating shaft 4122, the rotating bearing may be sleeved between the two fixing plates and outside the rotating shaft 4122. The corner piece 4123 is then fitted over the outside of the pivot bearing. In this way, the friction coefficient of the corner piece 4123 when rotating about the center axis of the rotating shaft 4122 can be reduced to some extent, and the rotation accuracy of the corner piece 4123 can be ensured.

In one embodiment, the corner piece 4123 may be, for example, an arc-shaped corner piece having an arc-shaped corner, and the arc-shaped corner of the arc-shaped corner piece may be provided with a through hole, and when being rotatably connected with the rotating shaft, the arc-shaped corner portion of the arc-shaped corner piece may be disposed between the two fixing plates 41212, and the rotating shaft 4122 may be inserted into the through hole of the arc-shaped corner. One end of the arc-shaped angle connecting piece can be rotatably connected with the hub, so that the steering wheel can rotate around the arc-shaped angle connecting piece. The other end of the arc-shaped angle connecting piece is fixedly connected with the steering driving device, so that under the driving of the steering driving device, the arc-shaped angle connecting piece rotates around the central shaft of the rotating shaft lever 4122, and a force perpendicular to the rotating direction of the hub is applied to the hub through one end, rotatably connected with the hub, of the arc-shaped angle connecting piece, and the rotating direction of the steering wheel is changed.

For example, the arc-shaped corner connector can be composed of an arc-shaped corner block and two fixing rods which are perpendicular to each other. Two dead levers all with this arc corner piece fixed connection. One of the two fixing rods is a cylindrical rod, and the cylindrical rod is rotatably connected with the wheel hub. The other of the two fixing bars may be a plate-shaped structure, and the other fixing bar is fixedly connected with the steering driving device.

Fig. 5 is a schematic structural view of a steerable wheel apparatus according to another embodiment of the present disclosure.

According to an embodiment of the present disclosure, a sensor may be provided for a steered wheel apparatus to sense whether a vehicle including the steered wheel apparatus is crushed. If the rolling is carried out, a rolled signal can be sent to a control system of the vehicle, so that the control system controls the vehicle to brake or controls the vehicle to power off, and the situations that the service life of the vehicle is shortened and the vehicle is damaged due to the fact that the vehicle is rolled for a long time are avoided.

For example, as shown in fig. 5, the steering wheel device 510 of this embodiment includes a distance sensing assembly 514 in addition to a wheel suspension assembly 511, a connecting assembly 512, and a steering wheel assembly 513.

The distance sensing assembly 514 may include a flapper 5141, a sensor mount 5142, and a sensor 5143, among others. The barrier 5141 may be fixedly coupled to a sidewall of a first mounting plate included in a mounting bracket of the wheel suspension assembly. The sensor fixing member 5142 is fixedly coupled to a sidewall of the coupling assembly 512, and the sensor fixing member 5142 is disposed opposite to the barrier 5141. The sensor 5143 is detachably connected with the connection assembly 512 via the sensor fixing member 5142. The sensor 5143 may be a distance sensor, for example.

In this way, when the vehicle is rolled, the mounting bracket of the wheel suspension assembly moves downward in the vertical direction relative to the connecting member as the vehicle chassis sinks, so that the distance between the baffle 5141 and the sensor 5143 is reduced. In the event that the sensor 5143 senses that its distance from the barrier 5141 is less than a predetermined distance, a crushed signal may be sent to the control system of the vehicle, for example, such that the control system controls the vehicle to brake or the vehicle to power down.

Moreover, through the height of the mounting rack in the reasonable design wheel suspension assembly, by means of the connection relation between the wheel suspension assembly and the connecting assembly and between the connecting assembly and the steering wheel device, the height of the vehicle chassis can be reduced when the vehicle is rolled until the vehicle chassis is contacted with the bottom surface. Therefore, the vehicle chassis can share the pressure born by the steering wheel and the driving wheel of the vehicle, and the condition that the steering wheel and the driving wheel are damaged due to overlarge pressure is avoided to a certain extent.

The wheel suspension assembly provided by the present disclosure will be described in detail below with reference to fig. 6 to 8.

Fig. 6 is a schematic structural view of a wheel suspension assembly according to a first embodiment of the present disclosure.

As shown in fig. 6, the wheel suspension assembly 611 of this embodiment may include a mounting frame 6111, an elastic member 6112, a first guide post 6113, and a fixing block 6114.

The mounting bracket 6111 may be fixedly connected to a chassis of a vehicle, and the mounting bracket 6111 may include a first mounting plate 61111 and a second mounting plate 61112. Wherein the two mounting plates can be fixedly connected with the vehicle chassis via a connecting piece. To secure the wheel suspension assembly to the vehicle chassis.

Two ends of the first guide post 6113 are respectively fixed on the first mounting plate 61111 and the second mounting plate 61112. The elastic member 6112 is sleeved on the first guide post 6113, and one end of the elastic member 6112 is fixedly connected to the first mounting plate 61111. The first mounting plate 61111 is higher than the second mounting plate 61112 in the vertical direction. The fixing block 6114 is sleeved on the first guide post 6113, and the fixing block 6114 is used for fixing the other end of the elastic member 6112.

For example, the fixing block 6114 may be provided with a through hole, and the size of the through hole is slightly larger than that of the first guide pillar 6113, so that the fixing block 6114 can move along the first guide pillar 6113. For example, the elastic member 6112 may be connected to the connecting assembly described above via the fixing block 6114, so that the elastic member is in transmission connection with the wheel assembly. It will be appreciated that the wheel assembly may be a steerable wheel assembly as described above, or a drive wheel assembly, as the present disclosure is not limited thereto.

When the wheel assembly moves up and down due to the fact that the ground is uneven, the wheel assembly can apply upward or downward force to the connecting assembly, so that the connecting piece drives the fixing block to move along the first guide pillar, and the elastic piece is compressed or stretched. For example, when the wheel passes through a convex hull on the ground, the elastic member is compressed, and the elastic member 6112 can provide an upward force to the vehicle chassis via the mounting bracket 6111, so that the distance between the vehicle chassis and the wheel can be maintained as much as possible. When the wheel passes through a pit on the ground, the elastic member is stretched, and the elastic member 6112 can provide a downward force to the vehicle chassis via the mounting bracket 6111, so that the distance between the vehicle chassis and the wheel can be maintained as much as possible. By the mode, the adaptability of the vehicle to the ground can be improved. Moreover, through setting up the elastic component, can reduce the degree that the vehicle jolted along with the unevenness of ground to a certain extent, provide the absorbing effect for the vehicle.

Fig. 7 is a schematic structural view of a wheel suspension assembly according to a second embodiment of the present disclosure.

In an embodiment, a movement guide mechanism may be further disposed on both sides of the elastic member of the wheel suspension assembly to prevent the elastic member from deviating in a direction perpendicular to the central axis of the first guide post during movement, so that the wheel assembly deviates from the central position of the vehicle. Therefore, the stability of the vehicle in the running process can be improved by arranging the moving guide mechanism.

For example, as shown in fig. 7, the wheel suspension assembly 711 of this embodiment includes a second guide post 7115 and a slider 7116 in addition to a mounting frame 7111, an elastic member 7112, a first guide post 7113 and a fixing block 7114.

Two ends of the second guide post 7115 are fixedly connected to the first mounting plate 71111 and the second mounting plate 71112, respectively. The sliding block 7116 is sleeved on the second guiding post 7115 and can slide along the second guiding post 7115. For example, the slider 7116 may be provided with a through hole similar to the fixing block described above, and the second guide post 7115 is fixedly connected to the first mounting plate 71111 and the second mounting plate 71112 after penetrating through the through hole, such that the slider 7116 is disposed between the first mounting plate 71111 and the second mounting plate 71112.

Wherein the slider 7116 may be connected with the wheel assembly via the previously described connection assembly, for example. Thus, the sliding block 7116 may be similar to the fixed block, and during the up-and-down movement of the wheel assembly, the sliding block 7116 may move along the second guide post 7115 under the driving of the connecting assembly. That is, the slider 7116 may be moved in synchronization with the fixed block, thereby providing a guide for the movement of the fixed block and the compression/elongation direction of the elastic member.

In one embodiment, as shown in fig. 7, two second guide posts 7115 and two sliders 7116 may be provided, and the two second guide posts 7115 are respectively disposed on two sides of the first guide post 7113. And the two sliding blocks are respectively sleeved on the two second guide pillars. In this way, the compression/elongation direction of the elastic member can be well defined.

In one embodiment, in order to make the arrangement of the elastic member effectively improve the adaptability of the vehicle to the ground, the elastic member can be elongated when the vehicle encounters a pit, and the natural length of the elastic member can be set. For example, the natural length of the elastic member may be set to be smaller than a preset length. The preset length may be less than a difference between a distance between the first mounting plate and the second mounting plate and a height of the fixing block. Namely, when the fixed block is jointed with the second mounting block, the elastic element is in a stretching state. It will be appreciated that the natural length of the resilient member and the spring constant of the resilient member may be set according to practical requirements. For example, the natural length of the elastic element can be set appropriately so that the vehicle chassis can move downwards until it is in contact with the ground when the vehicle is rolled.

In one embodiment, the wheel suspension assembly may further include a locking member for locking the second guide post to improve the stability of the connection between the second guide post and the mounting bracket.

For example, as shown in fig. 8, the wheel suspension assembly 811 of this embodiment includes a first locking member 8117 and a second locking member 8118 in addition to the mounting frame 8111, the elastic member 8112, the first guide post 8113, the fixing block 8114, the second guide post 8115, and the slider 8116.

Wherein the first locking member 8117 may be removably coupled to the first mounting plate 81111. One end of the second guide post 8115 can be sandwiched between the first locking member 8117 and the first mounting plate 81111. For example, a semi-cylindrical slot and a threaded hole may be provided on the first mounting plate 81111, and a semi-cylindrical slot and a threaded hole may be provided on the first locking member 8117. The second guide post 8115 can be tightened between the first locking member 8117 and the first mounting plate 81111 while the semi-cylindrical slot on the first locking member 8117 is aligned with the semi-cylindrical slot of the first mounting plate 81111 via the connection.

Similarly, the second locking member 8118 can be removably attached to the second mounting plate 81112. The other end of the second guide post 8115 is clamped between the second mounting plate 81112 and the second locking member 8118. The structure of the second locking member 8118 is similar to the structure of the first locking member 8117, and the structure of the first mounting plate 81111 is similar to the structure of the second mounting plate 81112, which will not be described again.

It will be appreciated that in the case of two second guide posts 8115, the second locking member 8118 and the first locking member 8117 may both be two.

It is understood that in order to avoid impact on the mounting bracket during movement, a washer or the like may be provided at a position where the first guide post and the second guide post are fixed to the surfaces of the first mounting plate and the second mounting plate opposite to each other.

In the technical scheme of the present disclosure, the processes of acquiring, collecting, storing, using, processing, transmitting, providing, disclosing and the like of the personal information of the related user all conform to the regulations of related laws and regulations, and do not violate the good custom of the public order.

The above detailed description should not be construed as limiting the scope of the disclosure. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may be made in accordance with design requirements and other factors.
