An embodiment of the present invention provides a separation locking mechanism, specifically, please refer to fig. 1 and fig. 2, fig. 1 is a schematic diagram illustrating a locking state of the separation locking mechanism in an embodiment of the present invention, fig. 2 is a schematic diagram illustrating a separation state of the separation locking mechanism in an embodiment of the present invention, where the separation locking mechanism 1 is applied in a vehicle steering transmission system, and includes:
the device comprises two separated cylinders 2 and 3, wherein a sliding cavity is arranged in each cylinder, and openings of the two sliding cavities are oppositely arranged;
the driving motor M is arranged at the bottom of the barrel;
the sliding piece 5 is arranged in the sliding cavity in a manner of sliding along the length direction of the cylinder body, and is used for realizing the separation and locking of the sliding piece 5 and the steering column 4 through sliding; one end part of the sliding part 5 is provided with a threaded hole, and an internal thread is arranged in the threaded hole;
It should be noted that, in the conventional vehicle steering transmission system, two universal joints with different cross shafts transmit torque and rotation angles, the characteristic of the universal joints with different speeds is that the steering transmission ratio shows wavy fluctuation, and the peak-valley amplitude and the position of the wave are influenced by the index angle and the phase angle.
Further, in the above embodiment, the outer surface of the sliding member 5 is provided with an external spline, and the sliding cavity is provided with an internal spline matching with the external spline.
In another embodiment of the present invention, referring to fig. 3, fig. 3 is a schematic structural diagram of a vehicle steering transmission system in one embodiment of the present invention, which includes a steering gear 6, a transmission shaft 7, a steering mechanism 8, a rotating electrical machine 9, and three separation locking mechanisms 1 (a first separation locking mechanism 11, a second separation locking mechanism 12, and a third separation locking mechanism 13, respectively) as described above, wherein:
the steering gear 6 is connected with one end of the transmission shaft 7 through a first separation locking mechanism 11; the steering control mechanism 8 is connected with the other end of the transmission shaft 7 through a third separation locking mechanism 13;

It should be noted that the steering gear is a reduction transmission device of an automobile steering system, and is more common, mainly comprises a rack-and-pinion steering gear and a recirculating ball steering gear, and is arranged at a specific position on an automobile suspension; the steering mechanism is used for transmitting steering related commands transmitted by a driver through a vehicle steering wheel, and different drivers have different requirements on vehicle driving. For example, when the vehicle speed is high, if the steering torque of the steering wheel is too large, part of drivers feel heavy steering; however, the steering torque of the steering wheel is too small, part of drivers can feel drifting, and dangerous working conditions are easy to occur, and the technical problem that the vehicle steering transmission system in the prior art cannot realize the center area response adjustment in the driving process is solved, so that the driver cannot correspondingly adjust the vehicle steering response according to individual driving requirements, and the driving experience of the driver is reduced.
In the embodiment, the adjustment of the steering angle and the phase angle is realized through the separation and locking of three separation locking mechanisms and the rotation control of one rotating motor, so that the adjustment of the steering response is realized. The transmission shaft of the vehicle is a vehicle component that can be connected or assembled, and can also move and rotate, and generally includes a multi-section structure (for example, a two-section structure in this embodiment), and of course, the structure of the transmission shaft can be provided with components such as an axle tube, a telescopic sleeve, a universal joint, and the like with reference to the prior art, so as to form a rotating body with high rotation speed and less support.
Another embodiment of the present invention provides a vehicle steering transmission method, which is applied to the vehicle steering transmission system described above, and specifically, referring to fig. 4, fig. 4 is a schematic flow chart of the vehicle steering transmission method in one embodiment of the present invention, where the method includes:
s1, receiving a central area response adjustment instruction input by a user, and acquiring current steering data of a steering column of a steering wheel of the vehicle;
s2, acquiring steering transmission ratio data of the vehicle based on the central area response adjusting instruction and the current steering data;
and S3, adjusting the separated locking states of the first locking mechanism, the second locking mechanism and the third locking mechanism, and correspondingly adjusting the real-time rotation angle of the rotating motor according to the steering transmission ratio data.
Further, in the above embodiment, the central area response adjustment instruction includes at least: fast response adjustment, medium speed response adjustment and slow response adjustment. Of course, other types of response adjustment instructions may be set according to different driving requirements of the driver, thereby further improving the driving comfort experience.
Because the steering transmission ratio can present wave-shaped fluctuation, and the peak-valley amplitude and the position of the wave are influenced by the index angle and the phase angle, in the embodiment of the invention, the relevant data of the steering transmission ratio are calculated, so that the data support is provided for the good adjustment of the rotating speed of the rotating motor, and the problem of inconsistent response of the steering wheel in the vehicle central area at different positions is solved.
Preferably, the steering gear ratio data includes at least: peak, valley and center positions.
Referring to fig. 5 as one of the preferred embodiments, fig. 5 is a partial schematic flow chart of a vehicle steering transmission method in one embodiment of the present invention, wherein for the above step S3: the separation locking state of the first locking mechanism, the second locking mechanism and the third locking mechanism is adjusted, and the real-time rotation angle of the rotating motor is correspondingly adjusted according to the steering transmission ratio data, and the method specifically comprises the following steps:
s31, separating the first locking mechanism from the second locking mechanism and locking the third locking mechanism;
s32, adjusting the real-time rotation angle of the rotating motor until the steering transmission ratio of the vehicle reaches the corresponding wave peak value and the corresponding wave valley value;
s33, separating the first locking mechanism and the third locking mechanism, and locking the second locking mechanism;
s34, adjusting the real-time rotation angle of the rotating motor until the steering transmission ratio of the vehicle reaches the corresponding central position;
s35, locking the first locking mechanism, the second locking mechanism and the third locking mechanism.
As can be seen from the above, different locking mechanisms are adjusted to enter different states, and at the same time, the rotating electrical machine is controlled to rotate by corresponding angles to enable the transmission ratio to reach the corresponding peak-to-valley value, and the peak-to-valley value is located at the central position in the vehicle steering process, and finally, the requirement of steering response adjustment is met by adjusting the angles and positions of the peak value and the valley value of the transmission ratio, as shown in fig. 6, fig. 6 shows a steering transmission waveform diagram of different response adjustment instructions in one embodiment of the present invention, the abscissa is the rotation angle of the steering wheel, the ordinate is the transmission ratio, and the whole diagram is a transmission ratio waveform, which includes a steering transmission waveform under high-speed response, a steering transmission waveform under slow-speed response, and a steering transmission waveform under medium-speed response.
For the sake of understanding, the basic principle of the separation locking mechanism and the steering transmission system and the method in the embodiment of the invention is as follows: the separation locking mechanism is a mechanical mechanism which can realize the separation or locking state of the steering column and the sliding piece; for the steering control of a vehicle, the rotation angle of a steering wheel and the rotation angle of wheels are different, and the reason for the arrangement is that the rotation angle of the vehicle is convenient to control, wherein the key function is that a transmission shaft and an unequal-speed universal joint (the universal joint is used for transmitting the torque of the steering wheel to the wheels) on the transmission shaft, the unequal-speed universal joint has the characteristic that the steering transmission ratio is wavy and can form a fixed waveform, and the fixed waveform represents the meaning that different transmission ratios are realized through the rotation angle of the steering wheel, so that different rotation angles of the wheels are realized, for example, the steering wheel is turned once and the wheels are turned ten degrees; the inventor finds that because each driver has different steering control force for the wheels, part of drivers want to realize steering control in a labor-saving mode, such as one-degree steering wheel turning and ten-degree steering wheel turning, and the other part of drivers want to realize steering control in a labor-saving mode, such as two-degree steering wheel turning and ten-degree steering wheel turning, in order to adapt to different driving force requirements of different drivers, the scheme optimizes the non-constant speed adjustment of the two cross shafts of the universal joint (the basic mechanical characteristics of the universal joint) by arranging the separation locking mechanism and the rotating motor on the transmission shaft, wherein the separation locking mechanism and the rotating motor are used for realizing the adjustment of the turning ratio between the inner shaft and the outer shaft of the transmission shaft, and combining a specific steering control method, so as to change the waveform of the steering transmission ratio, and different waveforms mean that the steering can be realized with different force when the vehicle turns, therefore, in addition to the fast response adjustment, the medium response adjustment and the slow response adjustment in the above embodiments (i.e., the three waveforms in fig. 6), other control strategies may be set to implement different waveforms, so as to achieve different response adjustment modes.
