The utility model has the advantages of simple structure, simpler manufacturing process and low cost, and the utility model satisfies the requirement of the integral structure of the small-sized children dune buggy.

Description

Small children's beach wheel hub

technical field

The utility model relates to a motorcycle accessory, in particular to a small-sized children's beach wheel hub.

Background technique

In order to meet the needs of installing brakes, the traditional motorcycle hub usually adopts an integral structure formed by die-casting aluminum alloy materials. The cost of materials used is high and the manufacturing process is complicated. Due to the small size and light weight of small children's beach cars, the front wheels generally do not need to be equipped with brakes, and in order to simplify the frame structure, the steering knuckle usually needs to be directly connected to the wheel hub. Therefore, starting from the needs of reducing costs, simplifying the manufacturing process and assembling, a wheel hub that is more suitable for small children's beach cars is specially designed.

Utility model content

The purpose of the utility model is to provide a small beach wheel hub for children with simple structure, simplified manufacturing process and convenient assembly of related parts of the whole vehicle.

The technical scheme of the utility model is: it includes a shaft sleeve and two oppositely arranged hub connecting plates, the shaft sleeve passes through the taper hole formed by flanging on the two hub connecting plates, and is fixedly connected with the two hub connecting plates respectively The flat parts of the two hub connecting plates are fitted together and fastened with bolts. The two hub connecting plates and the outer wall of the bushing enclose an annular space, and there are small holes on the two hub connecting plates to communicate the annular space with the atmosphere.

The wheel hub of the utility model is welded by a shaft sleeve and two opposite wheel hub connecting plates, which requires few parts, does not require a die-casting process, simplifies the process, and reduces the cost. The axle sleeve is used to install the axle of the wheel, and the hub connecting plate plays a role of supporting and connecting the axle sleeve. In order to increase the strength of the hub connecting plates, taper holes formed by flanging are provided on the two hub connecting plates, and the two hub connecting plates are arranged opposite to each other, so that the two hub connecting plates and the outer wall of the shaft sleeve enclose an annular space. There are small holes on the connecting plates of the two wheel hubs. When the wheels roll, the rainwater entering the annular space can be thrown out of the small holes, thereby preventing the rainwater from entering the annular space for a long time and damaging the wheel hubs.

The beneficial effect of the utility model is that the structure is simple, the manufacturing process is simplified, the cost is low, and it meets the needs of the overall structure of the small beach car for children.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a left side view of Fig. 1 .

Detailed ways

As shown in Fig. 1 and Fig. 2, the utility model is composed of a shaft sleeve 1, a hub connecting plate 2, a hub connecting plate 3, a bolt 5 and a wheel shaft dust cover 6, the hub connecting plates 2 and 3 are arranged oppositely, and the shaft sleeve 1 wears Go through the taper holes formed by flanging on the two hub connecting plates 2 and 3, and weld them together with the two hub connecting plates 2 and 3 respectively. Connection, the two hub connecting plates 2, 3 and the outer wall of the shaft sleeve 1 encircle an annular space 7, on the two hub connecting plates 2, 3 there are small holes 4 that make the annular space 7 communicate with the atmosphere, when the wheels roll, enter The rainwater in the annular space 7 can be thrown out from the small hole 4, so as to prevent the rainwater entering the annular space 7 from staying there for a long time and damaging the wheel hub.

It can be seen from Figures 1 and 2 that the small holes 4 are respectively arranged on the flanging and bending parts of the two hub connecting plates 2 and 3, and are evenly arranged along the direction of rotation, and each hub connecting plate is provided with three Small hole 4.

Fig. 1 shows that one end of the axle sleeve 1 is provided with an axle dust cover 6 to prevent dust from entering the axle of the wheel and causing pollution.
