Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
A steerable wheel assembly according to an embodiment of the present invention is described below with reference to fig. 1 to 6.
A steerable wheel assembly according to an embodiment of the present invention may include: a steering input shaft 1, a damper assembly 2, a mating mounting structure 3, a bearing assembly 4, and a wheel.
As shown in fig. 1 to 3, the fitting structure 3 is adapted to be fixed to a vehicle body, so as to fix the whole steering wheel assembly to the vehicle body through the fitting structure 3, thereby achieving stable connection between the steering wheel assembly and the vehicle body, and further ensuring safety and stability when the vehicle is steered.
The middle part of cooperation mounting structure 3 is formed with mounting sleeve 31, and the steering input shaft 1 vertically passes mounting sleeve 31 and is connected with the shock absorber base 21 of shock absorber subassembly 2 upper end, and steering input shaft 1 and mounting sleeve 31 clearance fit to make steering input shaft 1 can drive shock absorber base 21 and rotate and do not take place to interfere with mounting sleeve 31.
The steering input shaft 1 is suitable for driving the shock absorber assembly 2 to rotate around the axis of the steering input shaft 1, and the wheels are rotatably connected to the shock absorber assembly 2, so that the wheels can be driven to rotate while the steering input shaft 1 drives the shock absorber assembly 2 to rotate, so as to form a wheel steering unit capable of steering independently, wherein the steering input shaft 1 can be connected with a driving structure, so that driving force is provided through the driving structure to drive the steering input shaft 1 to rotate, and then the shock absorber assembly 2 and the wheels are driven to rotate and change directions.
Since the steering wheel assembly commonly used in conventional vehicles is in the form of: the steering gear inner rack moves to pull the steering gear two-end tie rods to move, the tie rods transmit force to the wheels, the steering function is achieved, the steering gear assembly is mounted on the frame, and the wheels are pulled by the tie rods to move, therefore, the arrangement positions of the wheels are limited, the space occupied by the whole steering wheel assembly is large, and the arrangement is inconvenient.
For this reason, the embodiment of the present invention uses the independent steering input shaft 1 to drive the damper assembly 2 and the wheels to rotate, so as to form an independent wheel steering unit, which is not limited by the position of the conventional tie rod of the steering gear, so that the arrangement position is not limited, and the arrangement space is smaller, and the arrangement on the vehicle body is more convenient.
And the traditional wheel steering is limited by a tie rod and only has a fixed rotation angle range and a small range, but the steering wheel assembly of the invention directly drives the steering input shaft 1 to drive the shock absorber assembly 2 and the wheels to rotate by using a driving structure, so the rotation angle is not limited, even the steering input shaft can carry out turnover movement, and 360-degree rotation can be carried out, therefore, the flexibility of the control of the wheel steering angle is effectively increased, the working condition switching of two-wheel steering and four-wheel steering can be better adapted, the wheels can realize +/-90-degree steering, and further, various steering driving modes such as front wheel steering, four-wheel steering, diagonal driving, transverse driving, pivot steering and the like can be realized, and the steering performance and the trafficability of the vehicle are improved.
Further, the bearing assemblies 4 are fixed to the upper and lower ends of the mounting sleeve 31 and are engaged with the steering input shaft 1, so that the steering input shaft 1 can rotate relative to the engagement mounting structure 3. That is, the bearing assemblies 4 are disposed at the upper and lower ends of the mounting sleeve 31 and are disposed on the steering input shaft 1 in a limiting manner, so as to clamp the mounting structure 3 between the bearing assemblies 4, and the steering input shaft 1 and the damper assembly 2 can be stably connected to the mounting structure 3, and then stably connected to the vehicle body, and the steering input shaft 1 can rotate relative to the mounting structure 3.
Wherein, because the bearing assemblies 4 are arranged at the upper and lower ends of the mounting sleeve 31, during the vibration of the vehicle, the axial force and the torsional force between the damper assembly 2 and the fitting mounting structure 3 will be applied to the bearing assemblies 4 without affecting the driving structure. Therefore, the shock absorber component 2 and the wheel can be ensured to rotate relative to the matching mounting structure 3 and cannot be damaged by axial force and torsional force, and therefore energy loss in the steering process of the wheel can be reduced, and the bearing strength is improved.
Still further, the upper end of the steering input shaft 1 has a first structure, and the bearing assembly 4 is limited and clamped between the first structure and the damper base 21. Namely, the bearing assembly 4 and the fitting mounting structure 3 are clamped between the first structure and the shock absorber base 21, so that the whole structure is more compact, and the axial force and the torsional force between the shock absorber assembly 2 and the fitting mounting structure 3 can be applied to the bearing assembly 4 and can not be transmitted to the driving structure, so that the driving structure is prevented from being damaged.

That is, the fitting structure 3 is a structural member independent from the vehicle body, which is not a part of the vehicle body, and needs to be separately mounted on the vehicle body, and therefore, the assembly of the steering wheel assembly can be facilitated. That is, the steering input shaft 1, the damper assembly 2, and the bearing assembly 4 may be assembled to the fitting structure 3 at the time of installation, and then the fitting structure 3 may be fixedly connected to the vehicle body.

Therefore, the upper bearing part 41 and the lower bearing part 42 can better bear the axial force and the torsional force between the shock absorber assembly 2 and the matching installation structure 3, so as to avoid influencing the installation safety of the driving structure.
Referring to fig. 4, the upper bearing portion 41 includes: the first race 411, the first race 412 and the first rolling structure 413 disposed between the first race 411 and the first race 412, wherein a lower end of the first race 411 is configured as a first mating end, the first mating end is fixedly mated with an upper port of the mounting sleeve 31, so that the first race 411 cannot move relative to the mating mounting structure 3, an upper end of the first race 411 has a first mating groove, and the first rolling structure 413 is disposed in the first mating groove, so that the first mating groove and the first race 412 are rotatably mated, so that the first race 412 can rotate in the first mating groove, and the steering input shaft 1 and the first race 412 are rotatably connected in synchronization, so that the steering input shaft 1 can drive the first race 412 to rotate relative to the first race 411 and the mating mounting structure 3.
Referring to fig. 4, for the same reason, the lower bearing portion 42 includes: the second race 421, the second race 422 and the second rolling structure 423 disposed between the second race 421 and the second race 422, wherein the upper end of the second race 421 is configured as a second mating end, the second mating end is fixedly mated with the lower port of the mounting sleeve 31, so that the second race 421 cannot move relative to the fitting mounting structure 3, the lower end of the second race 421 has a second mating groove, and the second rolling structure 423 is disposed in the second mating groove, so that the second mating groove and the second race 422 are rotatably mated, so that the second race 422 can rotate in the second mating groove, and the steering input shaft 1 and the second race 422 are synchronously and rotatably connected, so that the steering input shaft 1 can drive the second race 422 to rotate relative to the second race 421 and the fitting mounting structure 3.
Thereby, a stable rotation of the steering input shaft 1 with respect to the mating mounting structure 3 is achieved, and further a stable rotation of the damper assembly 2 and the wheels with respect to the mating mounting structure 3 is achieved.
Optionally, the steering input shaft 1 may be connected to the first collar 412 and the second collar 422 by interference fit, respectively, to achieve stable synchronous rotation; alternatively, the steering input shaft 1 may be spline-fitted to the first and second collars 412, 422, respectively, and may also be able to stably rotate in synchronization therewith.
In connection with the embodiment shown in fig. 1, 3 and 4, the damper assembly 2 comprises: the shock absorber comprises a shock absorber base 21 and two side damping arms 22 connected to the shock absorber base 21, wherein the upper ends of the two side damping arms 22 are respectively fixedly connected with the shock absorber base 21, wheels are connected between the lower ends of the two side damping arms 22, and the shock absorber assembly 2 is connected with a steering input shaft 1 through the shock absorber base 21 so as to transmit steering force and torque to the shock absorber assembly 2, and then the shock absorber assembly 2 and the wheels are driven to rotate.
