When the steering wheel end shaft 200 and the steering end shaft 300 are coupled, the steering wheel 1 and the wheels are coupled, and the vehicle enters a normal driving mode. When the steering wheel end shaft 200 and the steering end shaft 300 are decoupled, the steering wheel 1 and the wheels are decoupled and the vehicle enters a play mode.

It will be appreciated that the clutch mechanism may be used in any application where decoupling or coupling is required.
The following embodiments of the present invention will explain the structure and the operation principle of the clutch mechanism by taking the clutch mechanism as an example for application to a steering system of an automobile.
When the clutch mechanism is used in a steering system of an automobile, one of the first end shaft and the second end shaft is a steering wheel end shaft 200, and the other is a steering end shaft 300; when the first end shaft is coupled with the second end shaft, the steering wheel is coupled with the wheels, the steering wheel is operated to drive the wheels to steer, and the automobile enters a normal driving mode; when the first end shaft and the second end shaft are decoupled, the steering wheel and the wheels are decoupled, and when the steering wheel is operated to rotate, the wheels cannot be driven to steer, so that the automobile enters a game mode. Therefore, tire abrasion caused by repeated static friction between the wheels and the ground after the automobile enters a game mode can be avoided, and the realization of an automobile game scene scheme is facilitated.
The drive mechanism can be of various configurations, and in a preferred embodiment of the invention, the drive mechanism has a first drive member and a second drive member. One of the steering wheel end shaft 200 and the steering end shaft 300 is fixed by the second driving member, and the other is released or clamped by the clamping member.
The following description will explain the specific structure and operation of the clutch mechanism 100 according to the embodiment of the present invention by taking the example in which the steering wheel end shaft 200 is fixed by the second driving member and the steering end shaft 300 is released or clamped by the clamping member.
Referring to fig. 3 to 8, the first driving member and the second driving member are installed to be capable of rotating synchronously. And first driving piece can drive clamping piece axial translation from top to bottom, and when the clamping piece translated downwards to the axial, drive clamping piece radial outside translation, steering end axle 300 sets up the center at the clamping piece, when the clamping piece radially outwards move to with steering end axle 300 breaks away from, steering wheel end axle 200 and steering end axle 300 decoupling zero, the car gets into the recreation mode, and when the user operated steering wheel 1, steering wheel end axle 200, first driving piece and second driving piece all can rotate along with it, nevertheless steering end axle 300 can not rotate, and the rotation torque can not transmit the wheel to can not drive the wheel and turn to. When the clamping piece axially translates upwards, the second driving piece drives the clamping piece to radially translate inwards, when the clamping piece radially translates inwards to be in contact with the steering end shaft 300 and clamp the steering end shaft 300, the steering wheel end shaft 200 is coupled with the steering end shaft 300, the automobile enters a normal driving mode, when a user operates the steering wheel 1 to rotate, the first driving piece and the second driving piece rotate along with the steering end shaft 300, the steering end shaft 300 is driven to synchronously rotate, and wheels are driven by the steering end shaft 300, so that the wheels are driven to steer.
In a preferred embodiment, the first drive member includes a rotation mechanism 40 and a mount threadedly coupled to the rotation mechanism 40. Specifically, the mounting seat may include, for example, a circular ring-shaped base 51, an internal thread is formed on an inner circumferential surface of the base 51, and the rotating mechanism 40 includes a screw 43, and the screw 43 is inserted into the base 51. When the screw 43 is axially rotated, the base 51 can be driven to translate along the axial direction of the screw 43.
In order to drive the rotation mechanism 40 to rotate, the first driving part further includes a driving device for driving the rotation mechanism 40 to rotate. Preferably, the driving device may include, for example: a power element such as a motor 10 for providing a driving force, and a transmission mechanism for transmitting the driving force to the rotating mechanism 40 to drive the rotation thereof.
The structure of the transmission mechanism is various, and in a preferred embodiment, the transmission mechanism comprises: a first gear 20 coaxially installed with an output shaft of the motor 10, and a second gear 30 coaxially installed with the rotation mechanism 40, wherein the first gear 20 and the second gear 30 are engaged. Thus, when the motor 10 is powered to rotate, the first gear 20 rotates synchronously therewith, and the second gear 30 is driven to rotate; the second gear 30 rotates to drive the rotation mechanism 40 to rotate synchronously.
In a preferred embodiment, the diameter of the first gear 20 is smaller than the diameter of the second gear 30, and as such. The first gear 20 is meshed with the second gear 30 for transmission, so that the output torque of the motor 10 can be increased, the output rotating speed of the motor 10 can be reduced, the motor 10 with smaller volume and power can be selected to drive the rotating mechanism 40, and the installation of the driving device is facilitated.
To facilitate disassembly, in a preferred embodiment, the second gear 30 is mounted coaxially with the rotation mechanism 40 as follows. Specifically, a limiting column 41 is formed on the outer peripheral surface of one end of the rotating mechanism 40 close to the second gear 30, the length direction of the limiting column 41 is parallel to the axial direction of the rotating mechanism 40, a mounting hole is formed in the center of the second gear 30 corresponding to the rotating mechanism 40, and a limiting notch 31 is formed in the edge part of the mounting hole corresponding to the limiting column 41. When the rotating mechanism 40 is inserted into the mounting hole, the stopper post 41 is received in the stopper recess 31, whereby the rotating mechanism 40 can be prevented from rotating axially relative to the second gear 30.
The mount is driven to translate along the axial direction of the rotating mechanism 40 by driving the rotating mechanism 40 to rotate, and the clamp member is mounted on the mount and can translate axially along with the mount. As the mount translates axially downward, the clamp is driven by the rotation mechanism 40 to translate radially outward, releasing the stub shaft 300.
To achieve the above object. The mounting seat further comprises a plurality of positioning blocks 50 formed at one axial end of a circular base 51, the positioning blocks 50 are equally distributed at one axial end of the base 51, and two adjacent positioning blocks 50 are circumferentially spaced; the clamping member includes a plurality of jaws 60, and a jaw 60 is received in a circumferential space between each adjacent two of the positioning blocks 50.
The pawl 60 is radially translatable relative to the locating block 50, but is not axially translatable relative to the locating block 50. In order to achieve this function, a recess 63 is formed on the side of the catch 60 facing the positioning block 50, radially through the catch 60, and a projection 52 is formed on the side of the positioning block 50 facing the catch 60, corresponding to the recess 63, the projection 52 being received in the recess 63.
Further, to enable the drive dogs 60 to translate radially outward as the mount translates axially downward. A first tapered surface 42 extending radially outward is formed circumferentially on the outer peripheral surface of the rotating mechanism 40, the end of the first tapered surface 42 with the larger radial dimension faces the mounting seat, and an inner inclined surface 62 extending radially inward and abutting against the first tapered surface 42 is formed on the inner side wall of the jaw 60 at the end close to the rotating mechanism 40.
When the rotating mechanism 40 rotates in the forward direction, the mounting seat translates axially downward, and simultaneously drives the claws 60 to translate axially downward, and when the claws 60 translate axially downward, the claws 60 are driven by the first tapered surfaces 42 to translate radially outward, so as to be away from the steering end shaft 300 which is coaxial with the mounting seat. Thereby, the steering end shaft 300 can be decoupled from the steering wheel end shaft 200. The steering end shaft 300 is always maintained at the axial center of the mounting seat by other fixing structures. It is noted that the first tapered surface 42 produces a circumferential rotation relative to the inner ramped surface 62 of the dog 60 as the dog 60 is driven to translate radially outward.
When the rotation mechanism 40 is rotated in the reverse direction, the mount translates axially upward. At the same time, the pawls 60 on the mount are driven by the second driver to translate radially inward so that the pawls 60 can grip the steering end shaft 300, thereby coupling the steering end shaft 300 and the steering wheel end shaft 200.
In order to drive the jaws 60 to translate radially inward when the jaws 60 translate axially upward, a radially outwardly extending outer bevel 61 is formed on an outer side wall of one end of the jaws 60 remote from the rotating mechanism 40, a distal end of the outer bevel 61 being axially remote from the rotating mechanism 40; a second tapered surface abutting against the outer inclined surface 61 is formed on the second driving member. Wherein, the far end of the outer inclined surface 61 refers to the end of the outer inclined surface 61 which is far away from the axis of the mounting seat. As can be seen from fig. 5 and 7, the distal end of the outer slope 61 refers to the lower end of the outer slope 61. A second tapered surface is formed inside the lower open end of the second driver, and the end of the second tapered surface having a smaller radial dimension is located above.
The above-described manner couples the steering wheel end shaft 200 and the steering end shaft 300 by the jaw 60 applying a radial clamping force to the steering end shaft 300. When the steering wheel end shaft 200 is rotated, the steering end shaft 300 is rotated by the pawls 60. In order to achieve the synchronous rotation of the steering end shaft 200 and the steering end shaft 300, the clamping jaw 60 is required to apply a large clamping force to the steering end shaft 300. In a preferred embodiment, to enable more reliable coupling of the steering wheel end shaft 200 and the steering end shaft 300. An inner spline is formed on the inner side wall of the jaw 60, and an outer spline is formed on the outer side wall of the steering end shaft 300, and when the jaw 60 radially translates to contact with the steering end shaft 300, the inner spline can be matched with the outer spline, thereby realizing the spline connection between the jaw 60 and the steering end shaft 300. Wherein, the inner side wall of the jaw 60 refers to the side wall of the jaw 60 facing the steering end shaft 300.
Thus, since the steering wheel end shaft 200 is fixed to the second driving member, under the coupled condition, when the steering wheel end shaft 200 rotates, the second driving member is driven to rotate, and meanwhile, the second driving member drives the first driving member to rotate synchronously, and the claw 60 in the first driving member drives the steering end shaft 300 to rotate synchronously.
In a preferred embodiment, to enhance the coupling strength between the first and second drivers, external splines are formed on the external inclined surfaces 61 of the jaws 60 and internal splines are formed on the second tapered surface of the open end of the second driver. The external and internal splines cooperate with each other such that the dogs 60 are able to translate axially and radially relative to the second driver but do not rotate circumferentially relative to the second driver.
In addition, the jaw 60 is splined to the second driver, which also allows the first driver to more smoothly drive the mount in both axial and radial translation.
As described above, the first driving member and the second driving member are installed to be capable of rotating synchronously, and the specific installation manner may be various.
In a preferred embodiment, the second driving member is a hollow cylinder 70, the top end of the hollow cylinder 70 is coaxially fixed with the steering wheel end shaft 200, the bottom end of the hollow cylinder 70 is open, and the inner side of the open end is machined with the second taper surface along the circumferential direction, the second taper surface is coaxial with the hollow cylinder 70, and the end with smaller radial dimension is located above.
The clamping member is located at the lower open end of the hollow cylinder 70, and the rotating mechanism 40 is installed inside the hollow cylinder 70 and is coaxially held with the hollow cylinder 70. An opening is formed on a side wall of the hollow cylinder 70, and a driving device for driving the rotation mechanism 40 to rotate is installed in the opening and is fixedly connected to the hollow cylinder 70.
In order to ensure the coaxiality of the rotating mechanism 40 and the steering wheel end shaft 200, a radial partition 80 is further formed in the hollow cylindrical body 70, and the rotating mechanism 40 axially penetrates the radial partition 80 to rotate.
Specifically, the screw 43 of the rotating mechanism 40 and the portion of the rotating mechanism 40 where the first tapered surface 42 is formed are both located below the radial partition 80, and the second gear 30 fixed coaxially with the rotating mechanism 40 is located above the radial partition 80. By providing radial spacers 80, the coaxiality of the rotary mechanism 40 and the steering wheel end shaft 200 is further ensured.
