For example, a hydraulic brake needs to be matched with a hydraulic station of a certain capacity, which not only has a high procurement cost and occupies a large space, but also requires regular maintenance, which increases the failure points of the entire equipment and increases the maintenance cost of the entire equipment.

After the clutch device is separated, the transmission power source can be cut off, the permanent magnet synchronous motor enters an idling state, and the motor main shaft is in a non-rotating free state. This provides a better braking and reverse state for the brake or reverse, and at the same time, the adopted or selected braking and reverse equipment can be appropriately reduced in specifications.

[0027] Figure 1A This is a schematic structural diagram of a permanent magnet synchronous motor with a detachable motor rotor structure in a separated state according to the present invention; Figure 1BIt is a schematic diagram of the closed state structure of the permanent magnet synchronous motor with a detachable motor rotor structure of the present invention; the clutch permanent magnet synchronous motor of the present invention includes a stator 4, a rotor 3, a main shaft 2, and a casing 5, the rotor 3 is arranged on the main shaft 2, the stator 4 is arranged on the casing 5, the rotor 3 is arranged on the main shaft 2, the stator 4 is fixedly arranged in the casing 5, and the rotor 3 rotates relative to the stator 4; it also includes a torque output clutch device 1, the torque output clutch device 1 is connected to the main shaft 2 in a clutched state, the torque output clutch device 1 is arranged between the main shaft 2 and the rotor 3 in a clutched state, the torque output clutch device 1 can realize the separation state and the closing state between the main shaft 2 and the rotor 3, a first rotor support bearing 301 and a second rotor support bearing 302 are arranged between the main shaft 2 and the rotor 3, the torque output clutch device 1 includes a rotor support end face gear 101, an internal tooth end face gear 102, an end face gear clutch bearing 103, and an electromagnetic clutch slide 104.

[0028] Whether the rotor support end gear 101 and the internal tooth end gear 102 are meshed and matched determines whether the rotor 3 outputs torque to the outside; if the rotor support end gear 101 and the internal tooth end gear 102 are matched together, the rotor 3 can transmit the torque to the main shaft 2, and the rotor 3 rotates together with the main shaft 2 to output torque to the outside; if the rotor support end gear 101 and the internal tooth end gear 102 are not matched together, the rotor 3 only idles and cannot transmit the torque to the main shaft 2. At this time, the rotor 3 with its two ends arranged on the first rotor support bearing 301 and the second rotor support bearing 302, and the rotor support end gear 101 coaxially connected to the rotor 3 can only idle around the main shaft 2 synchronously, and the main shaft 2 cannot obtain any torque from the rotor 3. The rotor 3 cannot output any torque to the outside under this working condition.

[0029] The internal tooth end face gear 102 and the end face gear clutch bearing 103 are connected together, and the electromagnetic clutch slider 104 and the end face gear clutch bearing 103 are connected together. The internal tooth end face gear 102, the end face gear clutch bearing 103 and the electromagnetic clutch slider 104 form a whole. The internal tooth end face gear 102, the end face gear clutch bearing 103 and the electromagnetic clutch slider 104 move left and right along the axial direction of the main shaft 2 as a whole, thereby realizing the meshing transmission cooperation between the rotor bracket end face gear 101 and the internal tooth end face gear 102. After the electromagnetic clutch slider 104 is energized and is acted upon by the electromagnetic force, it can overcome the spring elastic force, or the electromagnetic clutch slider 104 is not acted upon by the electromagnetic force but only by the spring force, thereby driving the internal tooth end face gear 102 and the end face gear clutch bearing 103 to reciprocate left and right along the main shaft 2; Figure 1AAs shown, after the electromagnetic clutch slider 104 is acted upon by the electromagnetic force and overcomes the spring force, the electromagnetic clutch slider 104 drives the internal tooth end face gear 102 and the end face gear clutch bearing 103 to move leftward along the main shaft 2, and then the rotor bracket end face gear 101 and the internal tooth end face gear 102 are disengaged; Figure 1B The electromagnetic clutch slide 104 shown is not affected by electromagnetic force but only by spring force. The electromagnetic clutch slide 104 drives the internal tooth end face gear 102 and the end face gear clutch bearing 103 as a whole on the right side of the main shaft 2, and the rotor bracket end face gear 101 and the internal tooth end face gear 102 are engaged and contacted together. The end face gear clutch bearing 103 is arranged behind the electromagnetic clutch slide 104, and a hole bearing retaining ring is provided in the electromagnetic clutch slide 104 for limiting and fixing the end face gear clutch bearing 103.

[0030] Regardless of whether the rotor 3 outputs torque outward, the end face gear internal gear 1022 on the internal tooth end face gear 102 and the main shaft outer gear 201 on the main shaft 2 are always meshed and matched. At the same time, the internal tooth end face gear 102 overcomes the spring resistance of the closing spring 105 under the driving action of the electromagnetic force of the electromagnetic clutch slider 104 and moves horizontally left and right along the axial direction of the main shaft 2. The end face gear internal gear 1022 on the internal tooth end face gear 102 is always meshed with the main shaft outer gear 201 on the main shaft 2. The tooth surface of the main shaft outer gear 201 is longer than the tooth surface of the end face gear internal gear 1022. The end face gear internal gear 1022 can slide left and right relative to the main shaft outer gear 201. Synchronously, the internal tooth end face gear 102 can slide left and right relative to the main shaft 2, so that the rotor bracket end face gear 101 and the internal tooth end face gear 102 are clutched with each other. If the internal tooth end face gear 102 moves to mesh with the rotor support end face gear 101 under the action of the electromagnetic clutch slider 104 to obtain the output torque, the internal tooth end face gear 102 will simultaneously drive the main shaft 2 to rotate synchronously and output torque to the outside world; if the electromagnetic clutch slider 104 does not act on the internal tooth end face gear 102 to achieve the meshing and cooperation between the internal tooth end face gear 102 and the rotor support end face gear 101, the internal tooth end face gear 102 cannot obtain the output torque at this time, and the internal tooth end face gear 102 will remain stationary synchronously with the main shaft 2. Under this working condition, the main shaft 2 cannot output the output torque of the rotor 3 to the outside world. As shown in the figure, when the internal tooth end face gear 102 slides to the left position relative to the main shaft 2, the rotor bracket end face gear 101 and the internal tooth end face gear 102 are out of contact, and the rotor 3 and the internal tooth end face gear 102 only rotate idly together, and the rotor 3 cannot transmit the torque to the main shaft 2. The rotor 3 and the internal tooth end face gear 102 arranged on the first rotor bracket bearing 301 and the second rotor bracket bearing 302 rotate idly around the main shaft 2 together, and the main shaft 2 cannot output any torque to the outside at this time; as shown in the figure, when the internal tooth end face gear 102 slides to the right position relative to the main shaft 2, the rotor bracket end face gear 101 and the internal tooth end face gear 102 are in contact together, and the rotor 3 transmits the torque to the main shaft 2 through the rotor bracket end face gear 101 and the internal tooth end face gear 102 that are only matched together, and the rotor 3 and the main shaft 2 rotate together to transmit torque to the outside.

[0031] The rotor support end face gear 101 is provided with support end face teeth 1011 that cooperate with the internal end face gear 102, and the internal end face gear 102 is provided with internal end face teeth 1021 that cooperate with the rotor support end face gear 101; the rotor support end face gear 101 is provided with support end face teeth 1011 that cooperate with the internal end face teeth 1021 on the internal end face gear 102, and the internal end face gear 1021 is provided with internal end face teeth 1021 that cooperate with the support end face teeth 1011 on the rotor support end face gear 101. When the end face gear internal gear 1022 on the internal end face gear 102 can slide left and right along the main shaft external gear 201 on the main shaft 2, the support end face teeth 1011 and the internal end face teeth 1021 can cooperate with each other; as shown in FIG. Figure 1A As shown, the end face gear internal gear 1022 on the internal tooth end face gear 102 can slide to the left along the main shaft external gear 201 on the main shaft 2, so that the bracket end face teeth 1011 and the internal tooth end face teeth 1021 are out of contact; Figure 1B When the end face gear internal gear 1022 on the internal tooth end face gear 102 shown can slide to the right along the main shaft external gear 201 on the main shaft 2, the bracket end face teeth 1011 and the internal tooth end face teeth 1021 are engaged and matched, and the rotor bracket end face gear 101 and the internal tooth end face gear 102 are effectively matched with each other to realize the separation state and the closing state between the main shaft 2 and the rotor 3, so that the permanent magnet synchronous motor has a clutch function.

There is a sliding component limit chamber 5021 on the first housing end cover 502 for accommodating the electromagnetic clutch slider 104. The electromagnetic clutch slider 104 drives the internal tooth end gear 102 and the end gear clutch bearing 103 to slide left and right as a whole in the sliding component limit chamber 5021; 8 evenly distributed closing springs 105 are arranged in the sliding component limit chamber 5021. According to the actual motor model, the number of closing springs 105 evenly distributed in the sliding component limit chamber 5021 can be appropriately adjusted.

The rotor support end gear 101 is provided with support end face teeth 1011 that cooperate with the internal end face gear 102, and the internal end face gear 102 is provided with internal end face teeth 1021 that cooperate with the rotor support end gear 101. The support end face teeth 1011 provided on the rotor support end gear 101 and the internal end face teeth 1021 provided on the internal end gear 102 effectively cooperate with each other to achieve the separation and closing states between the main shaft 2 and the rotor 3, and thus provide the permanent magnet synchronous motor with an automatic clutch function. The end face gear internal gear 1022 on the internal end gear 102 can slide left and right along the main shaft external gear 201 on the main shaft 2, so that the support end face teeth 1011 and the internal end face teeth 1021 can cooperate with each other.

[0035] The bracket face teeth 1011 on the rotor bracket face gear 101, which mate with the internal face teeth 1021, and the internal face teeth 1021 on the internal face gear 102, which mate with the bracket face teeth 1011, effectively cooperate with each other to achieve a separation state and a closed state between the main shaft 2 and the rotor 3, thus providing the permanent magnet synchronous motor with a clutch function. The face gear internal gear 1022 on the internal face gear 102 can slide left and right along the main shaft external gear 201 on the main shaft 2, so that the bracket face teeth 1011 and the internal face teeth 1021 can be adjusted to interact with each other.

[0036] Figure 4A 1 is a schematic diagram of the separation state of the detachable motor rotor structure of the present invention; Figure 4B2 is a schematic diagram of the separation state of the detachable motor rotor structure of the present invention; Figure 4A and Figure 4B The end face gear internal gear 1022 on the internal tooth end face gear 102 shown can slide to the left along the main shaft external gear 201 on the main shaft 2. At this time, the electromagnetic clutch slider 104 receives external electricity, and the electromagnetic force released by the electromagnetic clutch slider 104 overcomes the elastic force of the closing spring 105, so that the electromagnetic clutch slider 104, the end face gear clutch bearing 103 and the internal tooth end face gear 102 as a whole slide axially to the left along the main shaft 2. The closing spring 105 is in a compressed state at this time, so that the bracket end face teeth 1011 and the internal tooth end face teeth 1021 are out of contact and cooperation.

[0039] like Figure 4C and Figure 4DThe end face gear internal gear 1022 on the internal tooth end face gear 102 shown can slide to the right along the main shaft external gear 201 on the main shaft 2. At this time, the electromagnetic clutch slide 104 has no electromagnetic force to overcome the elastic force of the 8 closing springs 105, so that the internal tooth end face gear 102 is closely engaged with the rotor bracket end face gear 101. The closing spring 105 is in an extended state at this time, so that the bracket end face teeth 1011 and the internal tooth end face teeth 1021 are in contact and fit.
