[0017] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] A noise-reducing track wheel, such as Figure 1-Figure 3 As shown, it includes a wheel body 1, which is covered with a wheel cover 2. The wheel cover 2 is arranged in two symmetrical pieces. The wheel cover 2 is arranged on the wheel body 1, which is used to form a main body for reducing noise. The wheel cover 2 is formed in a semicircular shape, so that the assembly of the two wheel covers 2 can form a covering for the wheel body 1. A plurality of grooves 3 are provided on the wheel cover 2. The length direction of the groove 3 is parallel to the axial direction of the wheel body 1. The inner wall of each groove 3 is covered with an elastic member, and the elastic member is deformably arranged in the groove 3 area. The formation of the groove 3 and the arrangement of the elastic member are used to form a noise reduction treatment for the contact surface between the wheel cover 2 and the track in contact with the wheel cover 2, so as to form a buffer for the contact between the track and the wheel cover 2 and reduce the size of the sound emitted during the collision. The groove 3 and the elastic member The force pieces are all replaced with the outer arc surface of the wheel cover 2 to form an integral, surrounding state of the wheel body 1. The elastic piece includes a pressing piece 4 and a flat cylinder 5. The flat cylinder 5 is fixedly arranged on the inner wall of the groove 3 of the wheel cover 2. The pressing piece 4 is arranged on the flat cylinder 5. The middle section of the pressing piece 4 extends into the groove 3 and is slidably connected with the wheel cover 2. The part of the pressing piece 4 extending out of the wheel cover 2 forms a gap with the wheel cover 2. The pressing piece 4 can abut against the wheel cover 2 when sliding. The pressing piece 4 is used to form contact with the track and form pressure on the flat cylinder 5 when in contact, so that the flat cylinder 5 is deformed. The flat cylinder 5 is set to memory metal. After being deformed by pressure, it can recover when the pressure is removed, thereby slowing down the movement speed of the track toward the axial direction of the wheel body 1 and reducing the force of the knocking.

[0019] The wheel cover 2 is provided with a countersunk hole 6 and a screw hole. The countersunk hole 6 between the two wheel covers 2 corresponds to the position of the screw hole, and a screw 7 is arranged between the two. When the wheel cover 2 is installed on the wheel body 1, the two wheel covers 2 are locked by the screw 7, so that the wheel cover 2 can cover the wheel body 1, which is convenient for users to install it. A pad 8 is bonded and connected to a section of the pressing plate 4 close to the wheel cover 2. A plurality of protrusions 9 are arranged on the pad 8. The pad 8 is made of rubber material. The pad 8 uses rubber material to form a noise reduction effect. The pressing plate 4 is also made of memory metal material. The memory metal material can minimize the deformation caused to the pressing plate 4 when the pressing plate 4 is subjected to pressure, thereby extending the service life of the pressing plate 4.
