Description

Technical Field

The present application relates to the technical field of vehicles, and more particularly, to a steering mechanism and a vehicle having the steering mechanism.

Background technique

Currently, the steering mode of vehicles on the market is front-wheel steering only. Front-wheel steering only makes the vehicle's turning radius larger. In order to achieve a smaller turning radius and be able to drive flexibly in a narrow field, the design generally needs to reduce the vehicle length or increase the steering angle. Under certain circumstances, the vehicle length cannot be reduced, and the steering angle can only be increased. However, too large a steering angle can easily cause the vehicle to skid. In addition, the steering handle needs to be turned at a larger angle, and the driver's hands need to move in a larger range, which results in a poor operating experience for the driver.

technical problem

The purpose of the present application is to provide a steering mechanism to solve the technical problems in the prior art that a large steering angle of a vehicle causes the vehicle to easily skid and the driver's operating experience is poor.

Technical Solutions

To achieve the above purpose, the technical solution adopted in this application is:

In a first aspect, a steering mechanism is provided, which is used to drive a first wheel and a second wheel to rotate in opposite directions relative to each other, and comprises: a frame, two first support seats, a second support seat, a steering paddle, two connecting rods, a steering angle lever, a first cable and a second cable; the frame comprises a first end and a second end which are spaced apart; the two first support seats are respectively pivotally connected to the two sides of the first end, the first support seat is used to support the first wheel; the second support seat is pivotally connected to the second end, and is used to support the second wheel;

The steering paddle is pivoted to the first end; the connecting rod corresponds to the first support seat one by one, one end of the connecting rod is correspondingly hinged to the two first support seats, and the other end of the connecting rod is correspondingly hinged to the two ends of the steering paddle; the steering angle lever is pivoted to the second end; a first cable, the first cable includes a third end and a fourth end, the third end is connected to the steering paddle, and the fourth end is connected to the steering angle lever; a second cable, the second cable includes a fifth end and a sixth end, the fifth end is connected to the steering paddle, and the sixth end is connected to the steering angle lever; wherein, the movement of the third end can pull the fourth end to move by the first cable, and the movement of the fifth end The sixth end can be moved by pulling the second cable.

When the steering paddle rotates to the right, the connecting rod hinged on the steering paddle pushes the first support seat to deflect to the left, thereby causing the first wheel connected to the first support seat to deflect to the left, and the third end and the fifth end will move to the right, causing the second cable to relax and the first cable to tighten, and the third end pulls the fourth end to move to the right through the first cable, and the sixth end moves to the left, at which time the second wheel deflects to the right; similarly, when the steering paddle rotates to the left, the connecting rod hinged on the steering paddle pushes the second support seat to deflect to the right, and the first wheel will deflect to the right, and the third end and the fifth end will also move to the left, causing the second cable to relax and the first cable to tighten, and the third end pulls the fourth end to move to the left through the first cable, and the sixth end also moves to the left, at which time the second wheel deflects to the left; in this way, the first wheel and the second wheel are linked in real time and rotate in opposite directions relative to each other. Since the steering directions of the first wheel and the second wheel are opposite, the radius of the moving track of the wheel is smaller, which reduces the turning radius of the vehicle. When the vehicle passes through a sharp turn, the smaller turning radius reduces the required turning angle, so that the centrifugal force on the vehicle will not change suddenly, the turning is relatively smooth, and the vehicle is not prone to skidding. At the same time, the turning radius is reduced, and the steering angle of the steering paddle can be relatively reduced when the driver is turning, which reduces the range of motion of the driver's hands and thereby improves the driver's operating comfort.

In one embodiment, the steering mechanism further includes two travel blocks, the travel blocks are arranged at both ends of the limiting slide rod, and the linear bearing is located between the two travel blocks.

By adopting the above technical solution, travel blocks are arranged at both ends of the limiting slide rod. The two travel blocks can limit the movement range of the linear bearing along the length direction of the limiting slide rod, and then limit the rotation angle of the steering angle lever, so that the rotation angle of the second wheel on the second support seat is within a controllable range.

In one embodiment, the steering mechanism further includes a steering handle, which is rotatably connected to the first end and an end of the steering handle is disposed on the steering paddle.

1 and 2 , the embodiment of the present application provides a steering mechanism 100 for driving a first wheel 210 and a second wheel 220 to rotate in opposite directions relative to each other. The steering mechanism 100 includes a frame 1, two first support seats 2, a second support seat 3, a steering paddle 4, two connecting rods 5, a steering angle lever 6, a first cable 7 and a second cable 8; the frame 1 includes a first end 11 and a second end 12 spaced apart; the two first support seats 2 are pivotally connected to the two sides of the first end 11 relative to each other, the first support seat 2 is used to support the first wheel 210; the second support seat 3 is pivotally connected to the second end 12, and is used to support the second wheel 220; the steering paddle 4 is pivotally connected to the first end 11; the connecting rod 5 corresponds to the first support seat 2 one by one, one end of the connecting rod 5 is correspondingly hinged to the first support seat 2, and the other end of the connecting rod 5 is correspondingly hinged to the movable end of the steering paddle 4, the movable end can rotate about the rotation center of the steering paddle 4, drive the two connecting rods 5 to move, and then drive the first The wheel 210 steers, and the steering angle lever 6 is pivotally connected to the second end 12; the first cable 7 includes a third end 71 and a fourth end 72, the third end 71 is connected to the steering paddle 4, and the fourth end 72 is connected to the steering angle lever 6; the second cable 8 includes a fifth end 81 and a sixth end 82, the fifth end 81 is connected to the steering paddle 4, and the sixth end 82 is connected to the steering angle lever 6; wherein, the movement of the third end 71 can be achieved by pulling the fourth end 72 by the first cable 7, and the movement of the fifth end 81 can be achieved by pulling the sixth end 82 by the second cable 8.

In this embodiment, the first support seat 2 is arranged at the first end 11, and the second support seat 3 is arranged at the second end 12, so as to realize the support of the first wheel 210 and the second wheel 220. The rotation of the steering paddle 4 will be transmitted to the corresponding two first support seats 2 through the two connecting rods 5, thereby driving the first wheel 210 arranged on the first support seat 2 to rotate, so as to realize the steering function of the first wheel 210. The first cable 7 and the second cable 8 connect the steering paddle 4 with the steering angle lever 6. The third end 71 on the first cable 7 and the fifth end 81 on the second cable 8 are arranged on the steering paddle 4 at intervals. When the steering paddle 4 rotates around its rotation center, the third end 71 will be displaced along its circular motion trajectory, thereby pulling the fourth end 72 on the first cable 7 to move; similarly, the fifth end 81 will also be displaced along its circular motion trajectory, thereby pulling the sixth end 82 on the second cable 8 to move. Since the third end 71 and the fifth end 81 have the same rotation center, the motion trajectory of the third end 71 and the fifth end 81 is the same circular trajectory.

The implementation principle of this embodiment is as follows: For the convenience of explanation, the movement plane of the third end 71 and the fifth end 81 is the xy plane, the line connecting the third end 71 and the fifth end 81 is the y-axis, the direction of the fifth end 81 away from the third end 71 along the y-axis direction is the left, and the direction of the third end 71 away from the fifth end 81 along the y-axis direction is the right; it is not difficult to understand that since the movement trajectories of the third end 71 and the fifth end 81 are the same circular trajectory and the third end 71 and the fifth end 81 are spaced apart, when the steering paddle 4 rotates to the right, the first wheel 210 will deflect to the left, and at this time the third end 71 and the fifth end 81 will also move to the right. Taking the embodiment shown in Figure 2 as an example, the third end 71 and the fifth end 81 move to the right, so that the second cable 8 is tensioned and the first cable 7 is relaxed, and the fifth end 81 pulls the sixth end 82 to the left through the second cable 8 to move When the steering paddle 4 rotates to the left, the first wheel 210 will deflect to the right. At this time, the third end 71 and the fifth end 81 will also move to the left, so that the second cable 8 is relaxed and the first cable 7 is tightened. The third end 71 pulls the fourth end 72 to move to the left through the first cable 7, and the sixth end 82 also moves to the left. At this time, the second wheel 220 deflects to the left. That is, when the first wheel 210 deflects to the right, the second wheel 220 deflects to the left; when the first wheel 210 deflects to the left, the second wheel 220 deflects to the right; thereby, the first wheel 210 and the second wheel 220 rotate in opposite directions relative to each other.

Please refer to FIG. 3 and FIG. 4 for comparison. FIG. 3 is a schematic diagram of the implementation of the front-wheel steering of a vehicle in the related art. The arrow direction is the direction of the vehicle's motion trajectory. The direction of the first wheel 210 away from the second wheel 220 is the front. The first wheel 210 is the front wheel and the second wheel 220 is the rear wheel. It can be understood that since the steering directions of the front wheel and the rear wheel are the same, the radius of the wheel's moving trajectory is larger, so that the vehicle's turning radius is larger. FIG. 4 is a schematic diagram of the implementation of the steering mechanism 100 provided in this embodiment. Since the steering directions of the front wheel and the rear wheel are opposite, the radius of the wheel's moving trajectory is smaller, so that the vehicle's turning radius is reduced. It can be understood that for a vehicle using the front-wheel steering method shown in FIG. 3, the larger the turning radius, the larger the turning angle required when turning. Due to its large turning radius, when it needs to pass through a relatively sharp curve, a larger turning angle is required, that is, the steering paddle 4 needs to rotate a larger angle. At this time, due to the large difference in the reduction of the turning radius, the centrifugal force on the vehicle is increased, and the vehicle is prone to side slip under the action of the centrifugal force. Likewise, for the driver, a larger turning angle means that the driver needs to rotate the steering paddle 4 to a greater extent, which makes the driver's operating comfort poor.

By adopting the above technical solution, the motion plane of the third end 71 and the fifth end 81 is the xy plane, the line connecting the third end 71 and the fifth end 81 is the y axis, the direction of the fifth end 81 away from the third end 71 along the y axis is the left, and the direction of the third end 71 away from the fifth end 81 along the y axis is the right. When the steering paddle 4 rotates to the right, the connecting rod 5 hinged on the steering paddle 4 pushes the first support seat 2 to the left. The third end 71 and the fifth end 81 also move to the left, so that the second cable 8 is relaxed and the first cable 7 is tightened. The third end 71 pulls the fourth end 72 to move to the right through the first cable 7, and the sixth end 82 moves to the left. At this time, the second wheel 220 deflects to the right; similarly, when the steering paddle 4 rotates to the left, the connecting rod 5 hinged on the steering paddle 4 pushes the second supporting seat 3 to deflect to the right, and the first wheel 210 will deflect to the right. At this time, the third end 71 and the fifth end 81 will also move to the left, so that the second cable 8 is relaxed and the first cable 7 is tightened. The third end 71 pulls the fourth end 72 to move to the left through the first cable 7, and the sixth end 82 also moves to the left. At this time, the second wheel 220 deflects to the left; in this way, the first wheel 210 and the second wheel 220 are linked in real time and rotate in opposite directions relative to each other. Since the first wheel 210 and the second wheel 220 turn in opposite directions, the radius of the wheel's moving track is small, so that the turning radius of the vehicle is reduced. When the vehicle passes through a sharp turn, the smaller turning radius reduces the required turning angle, so that the centrifugal force on the vehicle will not change suddenly during movement, the turning is relatively smooth, and the vehicle is not prone to side slip; at the same time, the turning radius is reduced, and when the driver is turning, the steering angle of the steering paddle 4 can also be relatively reduced, so that the range of motion of the driver's hands is reduced, thereby improving the driver's operating comfort.

As one of the optional implementations of this embodiment, in one embodiment, the first cable 7 and the second cable 8 are arranged crosswise; in another embodiment, the first cable 7 and the second cable 8 are arranged oppositely.

It can be understood that when the steering angle lever 6 rotates, the linear bearing 92 can move along the length direction of the limit slide bar 91, thereby controlling the second support seat 3 to deflect.

By adopting the above technical solution, the limiting slide rod 91 limits the movement of the steering angle lever 6, so that when the steering angle lever 6 drives the second support seat 3 to perform steering action, the movement is smoother and more stable, avoiding the steering void or tire shaking caused by the matching gap between the components.
