Detailed Description
It should be noted that, in the case of no conflict, the embodiments of the present application and the technical features of the embodiments may be combined with each other, and the detailed description in the specific embodiments should be interpreted as an explanation of the gist of the present application and should not be construed as unduly limiting the present application.
Referring to fig. 6, an embodiment of the present application provides a gear shifting apparatus, which includes a transmission 1 and a gear shifting assembly for changing a gear of the transmission 1, the transmission 1 includes a ratchet 11, an input shaft 14, a drive shaft 15, a first synchronizer 12, an output shaft 16, and a pre-selected gear 13, the gear shifting assembly includes a pawl 21 engaged with the ratchet 11, the pawl 21 is pressed into the ratchet 11 to lock the ratchet 11 when the vehicle is in a parking gear (P-gear), thereby locking the output shaft 16 of the transmission 1, and a hub 121 of the first synchronizer 12 is coaxially disposed with the ratchet 11 and is locked from rotation following the ratchet 11. The input shaft 14 is a hollow shaft sleeved on the drive shaft 15. The engaging teeth of the gear hub 121 of the first synchronizer 12 are first engaging teeth 122, the engaging teeth of the pre-selection gear 13 are second engaging teeth 131, the pre-selection gear 13 is engaged with the corresponding gear so that the rotation of the input shaft 14 of the gearbox 1 can be transmitted to the pre-selection gear 13, when the vehicle is in a parking gear, the first engaging teeth 122 are engaged with the second engaging teeth 131 so that the gear hub 121 of the first synchronizer 12 locks the pre-selection gear 13, and accordingly the input shaft 14 of the gearbox 1 is also locked. When the engine 4 rotates to drive the clutch 3 to generate a drag torque to act on the input shaft 14 of the gearbox 1 in the working state, and when the first combining teeth 122 of the gear hub 121 are meshed with the second combining teeth 131 of the pre-selection gear 13, the gear hub 121 of the first synchronizer 12 is locked together with the ratchet wheel 11 in the state of P gear, so that the pre-selection gear 13 and the input shaft 14 of the gearbox 1 are also locked, and the drag torque of the clutch 3 cannot drive the input shaft 14 of the gearbox 1 to rotate, and correspondingly cannot drive the pre-selection gear 13 to rotate, so that knocking vibration of the gearbox 1 is avoided.
However, in the related art, since the engagement state of the first coupling teeth 122 of the gear hub 121 and the second coupling teeth 131 of the pre-selection gear 13 is poor, the input shaft 14 of the transmission 1 rotates to drive the pre-selection gear 13 to rotate under the drag torque of the clutch 3 to generate knocking, so that the transmission 1 generates knocking vibration.
It will be appreciated that referring to fig. 6, 9 and 10, the first position P1 is shown as a critical engagement position of the first engaging tooth 122 of the gear hub 121 and the second engaging tooth 131 of the pre-selection gear 13, when the first engaging tooth 122 of the gear hub 121 of the first synchronizer 12 is located at the first position P1 relative to the second engaging tooth 131 of the pre-selection gear 13, the first engaging tooth 122 and the second engaging tooth 131 are just capable of engaging, and when the engagement depth of the first engaging tooth 122 relative to the second engaging tooth 131 is smaller than the corresponding engagement depth of the first position P1, the engaged state between the first engaging tooth 122 and the second engaging tooth 131 is poor, and slip may occur between the first engaging tooth 122 and the second engaging tooth 131, and the gear hub 121 of the first synchronizer 12 cannot lock the pre-selection gear 13, so that the gearbox 1 generates knocking vibration. The second position P2 shown in the drawing is the deepest position where the first coupling tooth 122 and the second coupling tooth 131 can mesh. The depth of engagement of the first and second coupling teeth 122, 131 at the second position P2 is greater than the depth of engagement of the first and second coupling teeth 122, 131 at the first position P1. When the first coupling tooth 122 of the gear hub 121 of the first synchronizer 12 is located between the first position P1 and the second position P2 with respect to the second coupling tooth 131 of the pre-selection gear 13, the first coupling tooth 122 of the gear hub 121 of the first synchronizer 12 and the second coupling tooth 131 of the pre-selection gear 13 can be well engaged, thereby locking the pre-selection gear 13 and the input shaft 14 of the transmission 1 and reducing the vibration of the transmission 1.
It will be appreciated that in the related art, due to the influence of the dimensional chain error, the engagement depth of the first engaging tooth 122 and the second engaging tooth 131 may be smaller than the engagement depth of the first engaging tooth 122 and the second engaging tooth 131 at the first position P1, resulting in slipping between the gear hub 121 of the first synchronizer 12 and the pre-selected gear 13, and the gear hub 121 of the first synchronizer 12 cannot lock the pre-selected gear 13, so that the input shaft 14 of the transmission 1 and the pre-selected gear 13 generate knocking vibration under the drag torque of the clutch 3.
In an embodiment, referring to fig. 6, the gearbox 1 includes a first gear 17, a second gear 18 and a gear shifting gear 19, the first gear 17 is disposed on the input shaft 14, the first gear 17 rotates along with the input shaft 14 of the gearbox 1, the second gear 18 is meshed with the first gear 17, the gear shifting gear 19 is synchronously disposed with the second gear 18 and rotates along with the second gear 18, the gear shifting gear 19 is meshed with the pre-selected gear 13, when the input shaft 14 of the gearbox 1 drives the first gear 17 to rotate under the action of drag torque of the clutch 3, the first gear 17 drives the second gear 18 to rotate, the gear shifting gear 19 rotates along with the second gear 18, and the gear shifting gear 19 drives the pre-selected gear 13 to rotate, so that the gearbox 1 generates knocking vibration.

In one embodiment, referring to fig. 8, the shift assembly further includes a transmission mechanism 25 drivingly connected to the shift hub 23, the transmission mechanism 25 has a boss 251, and rotation of the shift hub 23 drives the boss 251 on the transmission mechanism 25 to rotate, so that the boss 251 can drive the pawl 21 to press against the ratchet 11 to lock the ratchet 11.
In one embodiment, referring to fig. 8, the transmission mechanism 25 includes a fourth gear 252 and a fifth gear 253, and the boss 251 is located on the fifth gear 253.
In an embodiment, referring to fig. 8 and 9, when the position of the shift hub 23 rotates by a first angle relative to the reference position, the pawl 21 moves to the outer edge of the teeth of the ratchet 11 under the drive of the boss 251, and in this state, the shift hub 23 continues to rotate to press the pawl 21 further toward the ratchet 11 under the action of the boss 251 so as to lock the ratchet 11.
In one embodiment, referring to fig. 8 and 9, when the position of the shift hub 23 is rotated by a second angle relative to the reference position, the pawl 21 is engaged with the ratchet 11, and the position of the corresponding pawl 21 is closer to the ratchet 11 at the second angle relative to the position of the corresponding pawl 21 at the first angle.
In one embodiment, the pawl 21 is driven by the boss 251 to move to a limit position engaged with the ratchet 11, that is, the pawl 21 is pressed into the deepest position of the ratchet 11, and the shift hub 23 is rotated continuously to drive the boss 251 to press the pawl 21 toward the ratchet 11, so that the pawl 21 cannot be closer to the ratchet 11.
It will be appreciated that when the angle of the position of the shift hub 23 relative to the reference position is greater than the first angle and less than or equal to the second angle, the pawl 21 is preferably engaged with the ratchet 11 to lock the ratchet 11, and the park gear is in an operative condition, i.e., corresponds to a P-gear engaged.
In one embodiment, when the shift hub 23 rotates clockwise to make the reference rib 231 abut against the reference baffle 241, the shift hub 23 rotates counterclockwise by a first angle to make the pawl 21 move to the outer edge of the teeth of the ratchet 11 under the driving of the boss 251, and the shift hub 23 rotates counterclockwise by a second angle to make the pawl 21 move to the limit position engaged with the ratchet 11 under the driving of the boss 251.
In one embodiment, referring to fig. 9, the shift hub 23 has a groove 232, the shift assembly further includes a shift fork 26, one end of the shift fork 26 is located in the groove 232 and can move along the groove 232, the distance from the groove 232 to the rotation center of the shift hub 23 gradually changes, one end of the shift fork 26 is connected to the gear hub 121 of the first synchronizer 12, and when the shift hub 23 rotates, the shift fork 26 moves along the groove 232 of the shift hub 23, so as to push the first coupling teeth 122 of the gear hub 121 of the first synchronizer 12 to move toward the second coupling teeth 131 of the pre-selected gear 13.
In one embodiment, referring to fig. 8 to 10, when the shift hub 23 rotates by a first angle with respect to the reference position, the shift fork 26 pushes the first engaging tooth 122 of the tooth hub 121 of the first synchronizer 12 to be located at the first position P1 with respect to the second engaging tooth 131 of the pre-select gear 13. When the shift hub 23 is rotated by the second angle with respect to the reference position, the fork 26 pushes the first coupling tooth 122 of the hub 121 of the first synchronizer 12 to be located at the second position P2 with respect to the second coupling tooth 131 of the pre-selected gear 13.
In an embodiment, referring to fig. 9, a third position P3 is shown where the position of the shift hub 23 rotates by a first angle relative to the reference position, and the shift fork 26 is located in the groove 232 of the shift hub 23, and a fourth position P4 is shown where the position of the shift hub 23 rotates by a second angle relative to the reference position, and the shift fork 26 is located in the groove 232 of the shift hub 23.
In the related art, due to factors such as deviation of a size chain or wear, when the shift hub 23 rotates a first angle with respect to the reference position, the position of the first coupling tooth 122 with respect to the second coupling tooth 131 may deviate from the first position P1, and when the shift hub 23 rotates a second angle with respect to the reference position, the position of the first coupling tooth 122 with respect to the second coupling tooth 131 may deviate from the second position P2. When the vehicle is engaged in a park gear (P gear), the gear-shifting hub 23 may not be in a pre-selected gear position to enable the first engaging teeth 122 of the gear hub 121 of the first synchronizer 12 to be well engaged with the second engaging teeth 131 of the pre-selected gear 13, resulting in slipping between the first engaging teeth and the second engaging teeth, thereby enabling the transmission 1 to generate knocking vibrations under the drag torque of the clutch 3.
In view of this, an embodiment of the present application provides a method for debugging a gear shifting device, referring to fig. 1, the method includes:
step S101: setting a pre-selected gear position of the gear shifting hub 23, wherein the pre-selected gear position is located in a preset interval, and the preset interval is a position interval of the gear shifting hub 23 corresponding to a parking gear in an effective state;
step S102: when the engine 4 is in a working state and the vehicle gear is in a parking gear, acquiring the rotating speed of a transmission piece corresponding to the synchronized end of the first synchronizer 12;
step S103: when the rotating speed of the transmission part is larger than the preset rotating speed, the pre-selected gear position is adjusted so that the rotating speed of the transmission part is smaller than or equal to the preset rotating speed;
step S104: and recording a pre-gear position when the rotating speed of the transmission part is smaller than or equal to the preset rotating speed.
Thus, since the pre-selected gear position is located in the position interval of the gear shifting hub 23 corresponding to the parking gear (P gear) in the active state, when the vehicle is in the P gear, the position of the gear shifting hub 23 can be located in the pre-selected gear position, the rotation speed of the rotating member corresponding to the synchronized end of the first synchronizer 12 is compared with the preset rotation speed, the position of the pre-selected gear corresponding to the preset rotation speed is recorded, the rotation speed of the transmitting member is smaller than or equal to the preset rotation speed, the subsequent gear shifting equipment is then engaged into the parking gear (P gear), the position of the gear shifting hub 23 is located in the recorded pre-selected gear position, the rotation speed of the transmitting member corresponding to the synchronized end of the first synchronizer 12 is smaller than or equal to the preset rotation speed in the state that the vehicle is in the P gear, so that the rotation knocking degree of the transmitting member corresponding to the synchronized end of the first synchronizer 12 is rotated under the action of the drag torque of the clutch 3 is reduced, and knocking vibration of the gearbox 1 is reduced.
It will be appreciated that when the rotational speed of the transmission member corresponding to the synchronized end of the first synchronizer 12 is less than or equal to the preset rotational speed, the first engaging teeth 122 of the gear hub 121 of the first synchronizer 12 and the second engaging teeth 131 of the pre-selection gear 13 are preferably engaged, the pre-selection gear 13 is locked by the gear hub 121 of the first synchronizer 12, and neither the pre-selection gear 13 nor the input shaft 14 of the gearbox 1 is rotated and knocked under the action of the drag torque of the clutch 3, so as to reduce the knocking vibration of the gearbox 1.
In one embodiment, referring to fig. 6, the transmission member corresponding to the synchronized end of the first synchronizer 12 may be the input shaft 14 of the transmission 1.
In one embodiment, referring to fig. 6, the transmission member corresponding to the synchronized end of the first synchronizer 12 may be a pre-gear 13.
In an embodiment, referring to fig. 6, the transmission member corresponding to the synchronized end of the first synchronizer 12 may be the first gear 17, the second gear 18 or the shift gear 19.
In one embodiment, the transmission members corresponding to the synchronized ends of the first synchronizer 12 are different, and the corresponding preset rotation speeds may be different.
In an embodiment, the preset rotation speed may be 0 regardless of the type of the transmission member corresponding to the synchronized end of the first synchronizer 12.
In one embodiment, the corresponding preselected gear of shift hub 23 at the preselected gear position is a reverse gear. Thus, since the reverse gear is immediately adjacent to the P gear, the preselected gear is the reverse gear so that the preselected gear can be preselected relatively conveniently through the shift hub 23.
In one embodiment, the Reverse gear is the R (Reverse) gear.
In one embodiment, the pre-select gear 13 is a reverse gear.
In one embodiment, referring to FIG. 2, recording the pre-select position includes:
s105: the preselected gear position is saved to a register of a control system of the gear shifting device.
In this manner, the controller reads the preselected gear position in the register and when the vehicle is engaged in P gear, the control system controls the shift hub 23 to move to the preselected gear position stored in the register. Since the gear shifting hub 23 is located at the pre-selected gear position stored in the register, the rotation speed of the transmission member corresponding to the synchronized end of the first synchronizer 12 is smaller than or equal to the preset rotation speed, and knocking vibration of the gearbox 1 is reduced.

step S133: and updating the preselected gear position of the gear shifting hub 23 to a position of the gear shifting hub 23 corresponding to the rotating speed of the transmission part being smaller than or equal to the preset rotating speed.
In this way, the position of the shifting hub 23 is gradually changed to a more suitable position through the position increment, so that the rotating speed of the transmission piece corresponding to the synchronized end of the first synchronizer 12 is smaller than or equal to the preset rotating speed, the preselected gear position of the shifting hub 23 is updated to be the position of the shifting hub 23 corresponding to the preset rotating speed, the position is correspondingly recorded as the preselected gear position, the engine 4 is started later, the vehicle is in the P gear, the position of the shifting hub 23 is in the updated recorded preselected gear position, and the rotating speed of the transmission piece corresponding to the synchronized end of the first synchronizer 12 is smaller than or equal to the preset rotating speed, so that the knocking vibration of the gearbox 1 is reduced.
In an embodiment, during the adjustment of the pre-selected gear, the position of the gear shifting hub 23 may be adjusted multiple times, for example, by increasing the position of the gear shifting hub 23 by a factor of two based on the pre-selected gear position, updating the pre-selected gear position to the position of the gear shifting hub 23 by the factor of two, if the rotational speed of the transmission member is still greater than the preset rotational speed, continuing to increase one and updating the pre-selected gear position until the rotational speed of the transmission member is less than or equal to the preset rotational speed.

step S1231: the position of the shift hub 23 is rotated by at least one angular increment on the basis of the pre-selected gear position such that the rotational speed of the transmission is less than or equal to the preset rotational speed.
In this way, the position of the switching hub is adjusted by rotating the switching hub 23 by a certain angular increment, so that the position of the switching hub 23 is adjusted to a position where the rotational speed of the transmission is less than or equal to the preset rotational speed.
In an embodiment, the preset interval is an interval greater than or equal to the first included angle and less than or equal to the second included angle, and the angle increment is a ratio of a difference value between the second included angle and the first included angle to the natural number. Thus, the difference value between the second included angle and the first included angle is equally divided into a plurality of parts, and the angle value of each part is the angle increment. The position of the shift hub 23 can be better adjusted with the angle equally divided by the preset interval as the angular increment.
In an embodiment, the number of parts of the second included angle and the first included angle, that is, the natural number, is selected according to the actual needs, and is not particularly limited.
