The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

The present invention discloses a hub structure, see fig. 1 to 4, comprising: fixed wheel hub 1, shelter from mechanism 2, brake disc 3 and adjustment mechanism.

The fixed hub 1 comprises a hub flange 11 and fixed spokes 12, wherein the fixed spokes 12 are arranged on the periphery of the hub flange 11, and generally, the hub flange 11 and the fixed spokes are of an integral structure. The fixed spokes 12 are spaced around the periphery of the hub flange 11, rather than completely covering the entire hub. That is, the fixing spokes 12 are plural, and a space is provided between two adjacent fixing spokes 12.

The shielding mechanism 2 is rotatably connected with the hub flange 11, the shielding mechanism 2 rotates between a first position and a second position, the shielding mechanism 2 shields the interval in the first position, and the shielding mechanism 2 exposes the interval in the second position. Preferably, the shielding mechanism 2 has a central turntable 21 and a baffle 22, wherein the baffle 22 is fixedly disposed on the periphery of the central turntable 21, and the central turntable 21 is rotatably connected to the hub flange 11, it can be understood that the central turntable 21 can drive the baffle 22 to rotate relative to the fixed hub 1.

The brake disk 3 has a lower disk 31 and an upper disk 32, and the upper disk 32 rotates relative to the lower disk 31 at the time of braking; the adjustment mechanism is connected between the upper disc 32 and the shutter mechanism 2, and drives the shutter mechanism 2 to rotate between the first position and the second position.

The adjustment mechanism is described below in two embodiments.

Example 1

The adjusting mechanism is provided with a connecting rod 42, one end of the connecting rod 42 is connected to the upper disc 32, the other end of the connecting rod 42 is connected to the shielding mechanism, and the shielding mechanism 2 is driven to rotate through the connecting rod 42 along with the rotation of the upper disc 32 during braking.

Example 2

As shown in fig. 2 to 4, the brake disc 3 further has a brake shaft 33, and the upper disc 32 is rotatably provided on the brake shaft 33;

the adjusting mechanism comprises a rotating ring 41, a connecting rod 42 and a shifting sheet 43, the rotating ring 41 is rotatably sleeved on the brake shaft 33, and a blocking sheet 411 is formed on the rotating ring 41; the poking sheet 43 is arranged on the upper disc 32 and rotates along with the upper disc 32 to poke the blocking sheet 411 on the rotating ring 41; the link 42 connects the swivel 41 and the shutter mechanism 2.

In general, upper disc 32 moves toward lower disc 31 during braking, specifically, lower disc 31 and upper disc 32 are disposed in parallel and spaced apart from each other, and upper disc 32 also moves toward lower disc 31 during braking; the catch 411 is raised to mate with the paddle 43 when the upper tray 32 is moved towards the lower tray 31.

Preferably, the shutter device further includes a spring 44 and a fixing ring 45, the spring 44 is provided between the rotary ring 41 and the brake shaft 33, and after braking is completed, the upper disc 32 is returned to a position away from the lower disc 31, and the rotary ring 41 is rotated by the spring 44 to return the shutter mechanism 2 to the first position. The fixed ring 45 is mounted outside the swivel 41. Avoiding dislocation or damage of the swivel 41.

In the above two embodiments, although the structures are slightly different, they are all configured such that the shutter mechanism 2 is rotated by the rotation of the upper plate 32.

Of course, in embodiment 1, since the link 42 is a telescopic link 42, the upper disc 32 is generally moved in a direction to approach the lower disc 31 during braking, and therefore the link 42 is telescopic.

In embodiment 2, the movement is transmitted by the engagement of the moving piece 43 with the stopper 411 after the movement.

In connection with the two embodiments described above, during braking, the upper disc 32 transmits motion to the shielding mechanism 2 through the connecting rod 42, the shielding mechanism 2 rotates to expose the space between the fixed spokes 12, which is referred to herein as an open state, i.e., the shielding mechanism 2 is in the second position, and airflow flows into the space to cool the brake disc 3. The shielding state is correspondingly, namely the shielding mechanism 2 is located at the first position, namely when the vehicle normally runs (or when the vehicle is parked, namely the brake disc does not brake), the shielding mechanism 2 shields the interval, reduces the air flow and enables the vehicle to run more stably.

The hub structure of the invention further comprises an end cover 5 which is fixedly arranged outside the hub flange 11 and covers the central turntable 21.
