[0002] Chinese Patent Publication No. CN113788438A discloses a forklift brake auxiliary wheel, including an auxiliary wheel and a connecting assembly for connecting the auxiliary wheel to a connecting plate. The connecting assembly includes a steering shaft mounted on the connecting plate, the auxiliary wheel being rotatably mounted on the steering shaft, and a brake for braking the rotation of the auxiliary wheel being installed between the steering shaft and the auxiliary wheel. However, in actual use, the following drawbacks still exist: the aforementioned auxiliary wheel does not have an encoder installed, making it impossible to obtain accurate vehicle speed data in real time, thus failing to meet current usage requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a load-bearing wheel and its vehicle to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A load-bearing wheel, including

[0006] axle;

[0007] The load-bearing wheel is rotatably mounted at one end of the axle via a bearing.

[0008] An electromagnetic brake, one end of which is connected to the axle, and the other end to the load-bearing wheel; and

[0009] An encoder is mounted on the end of the wheel axle away from the electromagnetic brake and is coaxial with the wheel axle. The encoder output shaft is connected to a bushing on a flexible support, and the flexible support is connected to the load-bearing wheel.

[0010] Preferably, the electromagnetic brake has a fixed part and a movable part, which are connected to the wheel axle and the load-bearing wheel respectively by bolts.

[0011] Preferably, a retaining washer is installed on the outer end of the axle by a round nut, and the retaining washer abuts against the inner ring of the bearing. A bearing baffle is provided on the bearing wheel to abut against the outer ring of the bearing.

[0012] Preferably, a wheel cover is installed on the load-bearing wheel.

[0013] Preferably, the encoder wiring harness is electrically connected to the vehicle via a through hole on the wheel axle.

[0014] This application also provides a vehicle including the aforementioned load-bearing wheel.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention, by installing an encoder on the load-bearing wheel, can obtain accurate vehicle speed data in real time without affecting the vehicle width and distance, which is very beneficial to the lateral stability of the vehicle. At the same time, the encoder lead wire is led out through the hole on the wheel axle and connected to the vehicle wiring harness, making the wiring harness neat, not easy to be damaged, and improving its service life.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-3 The present invention provides a technical solution:

[0023] A load-bearing wheel, including

[0024] Wheel axle 1, one end of which is fixedly welded to the frame to keep it stationary;

[0025] The bearing wheel 2 is rotatably mounted on the other end of the axle 1 via a bearing 3. The inner ring of the bearing 3 is sleeved on the axle 1, and its outer ring is fitted with the bearing wheel 2, so that the bearing wheel 2 can rotate around the axle 1. A locking washer 11 is installed on the outer end of the axle 1 via a round nut 12, and the locking washer 11 abuts against the inner ring of the bearing 3. The locking washer 11 and the round nut 12 are used in pairs to lock the bearing 3 and prevent it from loosening. A bearing baffle 12 is bolted to the bearing wheel 2 and abuts against the outer ring of the bearing 3, so that it can restrain the outer ring of the bearing 3 from sliding along the axial direction of the axle 1.

[0026] An electromagnetic brake 4, one end of which is connected to an axle 1 and the other end to a support wheel 2, has a fixed part 8 and a movable part 9. The fixed part 8 and the movable part 9 are fixedly connected to the axle 1 and the support wheel 2 respectively by bolts. The fixed part 8 remains stationary with the axle 1, while the movable part 9 moves synchronously with the support wheel 2.

[0027] The encoder 5 is mounted on the end of the wheel axle 1 away from the electromagnetic brake 4 and is coaxial with the wheel axle 1. The output shaft of the encoder 5 is connected to the bushing 7 on the flexible bracket 6, and the flexible bracket 6 is connected to the bearing wheel 2, so that the output shaft of the encoder 5 can move synchronously with the bearing wheel 2, thereby obtaining real-time and accurate vehicle speed data, which is very beneficial to the lateral stability of the vehicle. The wiring harness of the encoder 5 is electrically connected to the whole vehicle through the through hole 14 on the wheel axle 1, which makes the wiring harness neat, not easy to be damaged, and improves its service life.

[0028] To prevent dust and damage to the encoder 8 from external objects, and to improve its appearance, a wheel cover 13 is installed on the load-bearing wheel 2.

[0029] This application also provides a vehicle including the aforementioned type of load-bearing wheel.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
