[0027] According to one aspect of the present invention, it further includes: a manual release control rod, which is arranged between the two-way clutch drive housing and the first housing and is sleeved on the axial control screw rod.

[0030] The tire is sleeved on the wheel hub.

[0031] To achieve the above object, the present invention further provides a control method for a two-way clutch control system, comprising:

[0032] Transmission mode:

[0033] After the upper computer sends a signal, the bidirectional clutch control motor drives the control motor worm to rotate, and the control motor worm drives the control motor turbine wire drum to rotate. After the control motor turbine wire drum rotates, it pushes the axial control screw to move axially in the positive direction, and transmits the axial motion to the axial control sleeve through the driving link pin, thereby driving the second clutch gear to push axially in the positive direction. The bidirectional clutch support plate integrated with the second clutch gear presses the power transmission friction plate, so that the second clutch gear and the first clutch gear remain in a relatively locked state;

[0034] The driving motor drives the first output gear to rotate and output power, drives the first clutch gear to rotate, and the second clutch gear rotates synchronously with the first clutch gear, drives the gear set to rotate through gear meshing, and the rotation of the gear set drives the second output gear to rotate to achieve power transmission;

[0035] Locking mode:

[0036] After the upper computer sends a signal, the bidirectional clutch control motor drives the control motor worm to rotate, and the control motor worm drives the control motor turbine wire drum to rotate. After the control motor turbine wire drum rotates, it pushes the axial control screw to move in the opposite axial direction, and transmits the axial movement to the axial control sleeve through the driving link pin, thereby driving the second clutch gear to push in the opposite axial direction. The bidirectional clutch support plate integrated with the second clutch gear presses the brake friction plate, so that the second clutch gear and the inner wall of the first housing are kept in a relatively locked state, and then the locking force is transmitted to the second output gear through gear meshing, thereby realizing the transmission of braking force;

[0037] At the same time, the driving motor drives the first output gear to rotate and output power, drives the first clutch gear to rotate, the second clutch gear is separated from the first clutch gear, the power transmission path is disconnected, and the driving motor is protected;

[0038] Electric push mode:

[0039] After the upper computer sends a signal, the bidirectional clutch control motor drives the control motor worm to rotate, and the control motor worm drives the control motor turbine wire drum to rotate. After the control motor turbine wire drum rotates, it pushes the axial control screw to move axially, and transmits the axial movement to the axial control sleeve through the driving connecting pin, thereby driving the second clutch gear to move to the middle state between power transmission and braking. The bidirectional clutch support plate integrated with the second clutch gear is in a state where both power and brake are separated, cutting off the power transmission and brake transmission channels;

[0040] The driving motor drives the first output gear to rotate and output power, drives the first clutch gear to rotate, and the second clutch gear rotates synchronously with the first clutch gear, drives the gear set to rotate through gear meshing, and the rotation of the gear set drives the second output gear to rotate to achieve power transmission;

[0041] Manual push mode:

[0042] The manual separation control rod is driven to rotate a certain angle, so that the axial control screw rod is transformed from the axial locked state to the axial free state, and the axial floating state is made so that the axial control sleeve is simultaneously in the bidirectional unlocked state, and the second clutch gear and the first clutch gear are disconnected and locked from the first housing;

[0043] The driving motor drives the first output gear to rotate and output power, drives the first clutch gear to rotate, and the second clutch gear rotates synchronously with the first clutch gear, drives the gear set to rotate through gear meshing, and then transmits power to the second output gear through gear meshing to realize power transmission.

[0044] According to the solution of the present invention, the present invention adopts an integrated shell packaging design, integrates a drive motor module and a two-way clutch module, switches the drive motor module in the clutch state, and manually switches the control module. The integrated solution avoids the coordination problem between the independent modules, uniformly controls the quality, replaces steel with plastic according to the load arrangement, is extremely lightweight, and effectively controls the cost;

[0045] According to the solution of the present invention, the present invention adopts a controllable two-way clutch, which separates the motor power in the braking state and separates the brake disc in the power transmission state, without a simultaneous engagement state, greatly reducing system risks;

[0046] According to the solution of the present invention, the present invention adopts a controllable two-way clutch. In the manual separation state, the clutch two-way friction plate is in a two-way separation state, that is, there is no reverse transmission and no braking. The wheel hub only drives the two sets of transmission teeth to idle, without unnecessary driving power consumption, which improves the user experience.

[0047] According to the solution of the present invention, the present invention adopts a controllable two-way clutch, which can realize free switching among the three states of power transmission, braking, and suspension promotion by detecting the position of the clutch control module. The manual unlocking wrench is only used as an emergency operation under extreme power failure conditions, and the degree of intelligence is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS
