Referring to FIG. 1, a wheel reduction assembly 100 is shown in its configuration that may be used in an automobile. The embodiment of the invention provides a hub reduction gear assembly 100 capable of realizing speed regulation of two gears, and the hub reduction gear has the characteristics of simple structure and small occupied space, so that the automobile layout is more reasonable.
In an embodiment of the present invention, the hub reduction assembly 100 includes a planetary gear mechanism 110, a frame barrel 120, a tray 130, and a drive assembly 140; the planetary gear mechanism 110 comprises a gear ring 111, a sun gear 112, a planetary gear 113 and a planet carrier 114, wherein the planetary gear 113 is respectively in meshing transmission with the sun gear 112 and the gear ring 111, the planet carrier 114 is in transmission connection with the planetary gear 113, the sun gear 112 is used for being in transmission connection with a driving motor, and the planet carrier 114 is connected with the frame barrel 120; the driving assembly 140 is in transmission connection with the ring gear 111, and is configured to drive the ring gear 111 and the frame barrel 120, so as to drive the sun gear 112 and the frame barrel 120 to be in transmission connection, or is configured to drive the ring gear 111 and the tray 130 to be matched, so as to drive the planet carrier 114 and the frame barrel 120 to be in transmission connection.
It should be noted that the frame barrel 120 is used for driving connection with a hub of an automobile. The tray 130 is fixed relative to the body of the automobile. The planetary gear mechanism 110 is in transmission connection with a driving motor, and the driving motor is used for driving the planetary gear mechanism 110 to move. In the planetary gear mechanism 110, a driving motor is in transmission connection with a sun gear 112, and the sun gear 112 drives a planetary gear 113, a ring gear 111 and a planet carrier 114 to move. Meanwhile, the driving assembly 140 can drive the gear ring 111 to move, so that the gear ring 111 is matched with the tray 130 or the frame barrel 120. When the ring gear 111 is matched with the frame barrel 120, the ring gear 111 and the planet carrier 114 are in transmission connection with the frame barrel 120, and at the moment, the sun gear 112 can directly drive a hub and a tire connected with the frame barrel 120. The output motion of the driving motor is directly transmitted to the frame barrel 120 and the hub connected with the frame barrel 120 through the sun wheel 112, so as to drive the hub and the tire to rotate. When the ring gear 111 is engaged with the tray 130, the ring gear 111 is also in a fixed state since the tray 130 is fixed with respect to the body of the automobile. At this time, the ring gear 111 is separated from the frame barrel 120, and the planet carrier 114 is driven by the frame barrel 120. The output motion of the driving motor is transmitted to the frame barrel 120 and the hub connected with the frame barrel 120 through the sun gear 112, the planet gear 113 and the planet carrier 114, so as to drive the hub and the tire to rotate.
That is, the hub reduction gear assembly 100 provided by the embodiment of the present invention has at least two gears: firstly, the transmission is realized through the transmission of the sun wheel 112 and the frame barrel 120; and secondly, the transmission between the planet carrier 114 and the frame barrel 120 is realized. The first transmission ratio when the sun gear 112 is in transmission connection with the frame barrel 120 and the second transmission ratio when the planet carrier 114 is in transmission connection with the frame barrel 120 are different, so that the speed regulation of the wheel reduction assembly 100 in two gears is realized.
In the present embodiment, the sun gear 112 and the planet carrier 114 can be drivingly connected to the frame barrel 120 and drive the hub and the tire to rotate. The transmission ratio of the sun wheel 112 and the planet carrier 114 is different when the sun wheel 112 and the frame barrel 120 are in transmission connection, and under the condition that the rotating speeds of the driving motors are the same, when the sun wheel 112 and the frame barrel 120 are in transmission connection, the rotating speeds of the hub and the tire at the output end are different, and when the planet carrier 114 and the frame barrel 120 are in transmission connection, the rotating speeds of the hub and the tire at the output end are different, so that two-gear speed regulation of the hub and the tire is realized.
Further, when the sun gear 112 is in transmission connection with the frame barrel 120, the sun gear 112 directly drives the frame barrel 120, and the transmission ratio is 1 at this time, so that the whole vehicle can be driven at a higher running speed. When the ring gear 111 is matched with the tray 130 under the action of the driving component 140, the sun gear 112 drives the planet gears 113, the planet gears 113 drive the planet carrier 114 to rotate, the planet carrier 114 further drives the hub connected with the frame barrel 120 to rotate, the transmission ratio is greater than 1, and the transmission ratio can be set to be 3, 4 or other values.
It should be noted that, when the entire vehicle normally runs, the sun gear 112 directly drives the frame barrel 120, and the transmission ratio at this time is 1, the entire vehicle speed is high, the required torque is small, and the requirement of high-speed running is met. However, when the vehicle meets some special working conditions, such as climbing some heavy slopes or loading and unloading garbage piles, the whole vehicle needs to output larger torque, but the rotating speed is relatively low, the driving assembly 140 drives the gear ring to move at the moment, the wheel edge on the bridge belt is decelerated, the output torque is larger, the rotating speed is relatively low, and the requirement of the whole vehicle on the special working conditions is met. The whole vehicle has better economy and stronger working condition adaptability.
It should also be noted that the transmission connection between the sun gear and the driving motor may be a direct transmission connection or an indirect transmission connection, for example, the transmission connection between the driving motor and the sun gear may be: driving motor, reduction gear, semi-axis and wheel reduction gear.

That is, the driving member 141 moves the retainer ring 142, so that the retainer ring 142 moves the ring gear 111. The connecting mode has the characteristics of simple structure and small occupied space, is favorable for saving the space occupied by the wheel-side reducer assembly 100, improves the space utilization rate of the whole vehicle, and ensures that the structure is more compact and reasonable.

That is, the driving member 141 may be driven by a pneumatic member.
Referring to fig. 1, the driving member 141 may be a solenoid valve, which is installed on the tray 130 or the vehicle body and is used for sucking the retainer ring 142.
