Description

Technical Field

[0001] This utility model relates to the field of vehicle control, and more specifically, to a device for suppressing vehicle deviation and a vehicle. Background Technology

[0002] Straight-line stability is one of the most important performance characteristics of a car, and also the one most easily perceived by the driver. For most vehicles, poor centering and self-centering require constant adjustments to the steering wheel angle to maintain a straight line, easily leading to driver fatigue. Vehicle pull-to-side deviation is a systemic problem involving multiple systems such as four-wheel alignment, wheels and tires, suspension, and steering. Numerous influencing factors are interconnected, making it a long-standing challenge in the industry. Therefore, suppressing pull-to-side deviation is an urgent problem to be solved.

[0003] Existing technologies primarily focus on improving steering wheel return-to-center performance. For cars on the road, a more common issue is when driving over sloping roads or potholes. Due to the road surface incline, the wheels exert an additional lateral force on the steering wheel, resulting in a lateral torque that causes the vehicle to veer off course. Therefore, addressing this lateral torque and improving centering performance is a problem that needs to be solved. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art by providing a device and vehicle for suppressing vehicle deviation, in order to solve the problem that existing methods for suppressing deviation are ineffective.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a device for suppressing vehicle deviation.

[0007] A device for suppressing vehicle deviation includes a damping bearing, a column connector, and a spindle connector;

[0008] One of the inner and outer rings of the damping bearing is connected to the column connector;

[0009] The other of the inner and outer rings of the damping bearing is connected to the spindle connector;

[0010] The spindle connector is connected to the steering spindle;

[0011] The tubing connector is connected to the steering tubing.

[0012] Damping bearings require a certain starting torque to rotate. In other words, when small bumps occur, damping bearings can suppress steering wheel rotation, provide centering force, and suppress deviation.

[0013] In the case of the deviation torque generated by the road surface inclination, in order to keep the steering wheel in the center and inhibit the vehicle deviation, the damping force generated by the damping bearing needs to be set to be greater than the deviation torque, so as to inhibit the deviation of the steering wheel caused by the road surface inclination and bump.

[0014] Further, one or all of the pipe column connecting piece and the mandrel connecting piece adopt a spline shaft and a spline sleeve connection.

[0015] Further, one or all of the pipe column connecting piece and the mandrel connecting piece adopt a gear connection.

[0016] Further, the damping bearing comprises a calibration locking mechanism.

[0017] In order to adapt to various vehicle models and match the center-keeping force according to the actual vehicle, a damping bearing starting torque adjusting mechanism is designed, which can change the starting torque of the damping bearing through adjustment, thereby adapting the parameters to specific vehicles.

[0018] Further, the vehicle deviation inhibition device further comprises an elastic component.

[0019] The elastic component is a double-wound spring or a torsion spring, one end of the elastic component is connected with the inner ring of the damping bearing or one of the pipe column connecting piece and the mandrel connecting piece.

[0020] The other end of the elastic component is connected with the outer ring of the damping bearing or the other of the pipe column connecting piece and the mandrel connecting piece.

[0021] Taking a double torsion spring as an example, the return force calculation formula of the double torsion spring is:

[0022] M θ = K * θ

[0023] In the formula, K is the spring torsion force, and θ is the torsion angle.

[0024] Therefore, the return torque generated by the double torsion spring can make the steering wheel return to the center and keep the left and right forces consistent.

[0025] The utility model further provides a vehicle.

[0026] A vehicle comprises the vehicle deviation inhibition device as described above, the pipe column connecting piece of the vehicle deviation inhibition device is connected with a steering pipe column, and the mandrel connecting piece is connected with a steering mandrel.

[0027] Compared with the prior art, the utility model has at least the following beneficial effects: the damping bearing is installed between the steering column and the steering spindle in the utility model, the steering wheel rotation has the middle position keeping torque, when small jolt appears, the damping bearing can restrain the steering wheel rotation, provides the middle position keeping force, restrains the deviation.

[0034] In order to make the utility model's purpose, technical scheme and advantage more clearly, the following is with the drawing and example, and the utility model is further detailedly explained.It should be understood that the specific example described here is only used to explain the utility model, and is not used to limit the utility model.

[0035] A kind of deviation device for inhibiting vehicle travel, see Figure 1 、 Figure 2 Including, damping bearing 1, pipe column connecting piece 2, spindle connecting piece 3, elastic assembly 4;

[0036] One of the damping bearing 1 inner ring and outer ring is connected with pipe column connecting piece 2;

[0037] Another of the damping bearing 1 inner ring and outer ring is connected with spindle connecting piece 3;

[0038] The spindle connecting piece 3 is connected with steering spindle;

[0039] The pipe column connecting piece 2 is connected with steering column.

[0040] When the steering wheel rotates, the steering column and the steering spindle will rotate. Since the damping bearing 1 is connected to the steering column and the steering spindle through the connecting members, the damping bearing 1 can inhibit the rotation deviation caused by the small steering torque.

[0041] It should be noted that the connection between the column connecting member 2, the spindle connecting member 3 and the steering spindle and the steering column can be achieved by clamping, bonding, spline, gear, connecting member connection and the like.

[0042] In the embodiment, the spindle connecting member 3 is connected to the steering spindle by spline shaft and spline sleeve, and the column connecting member 2 is connected to the steering column by connecting member.

[0043] The damping bearing 1 comprises a tuning and locking mechanism.

[0044] Specifically, there is a bearing adjusting sleeve between the outer ring and the inner ring of the damping bearing 1. The outer surface of the adjusting sleeve and the outer bearing are connected by threads, and the inner ring of the damping bearing 1 is matched with the adjusting sleeve by an axial slope. By changing the height of the adjusting sleeve into the bearing, the compression force of the inner ring and the outer ring of the bearing is adjusted, so that the damping force is adjustable. After the adjustment is completed, the locking device is locked.

[0045] In the embodiment, the damping torque is adjusted to be greater than the deviation torque and less than the return torque, as shown in Figure 3 In this case, the damping torque can overcome the deviation torque to achieve centering. When the direction needs to be returned, the return torque is greater than the damping torque, which can make the steering wheel return to the original position.

[0046] The elastic assembly 4 is a double-volute spring or a torsion spring. One end of the elastic assembly 4 is connected to the inner ring of the damping bearing 1 or one of the column connecting member 2 and the spindle connecting member 3.

[0047] The other end of the elastic assembly 4 is connected to the outer ring of the damping bearing 1 or the other of the column connecting member 2 and the spindle connecting member 3, as shown in Figure 4

[0048] It can be understood that the inner ring of the damping bearing 1 can be connected to any one of the column connecting member 2 and the spindle connecting member 3, as long as the outer ring of the damping bearing 1 is connected to the other of the column connecting member 2 and the spindle connecting member 3. Therefore, one end of the elastic assembly 4 can be connected to the outer ring of the damping bearing 1 or the connecting member connected to the outer ring of the damping bearing 1, as long as the other end of the elastic assembly 4 is connected to the inner ring of the damping bearing 1 or the connecting member connected to the inner ring of the damping bearing 1.

[0049] A vehicle comprises the vehicle running deviation inhibiting device as described above. The column connecting member of the vehicle running deviation inhibiting device is connected to the steering column, and the spindle connecting member is connected to the steering spindle. The final mounting structure is shown in Figure 5 .​

More specifically, many modifications and variations of the subject combination layout can be made in the details of construction and / or layout within the scope and range of equivalents of the application.
