The axle may be unitary, such as a large barbell, with both ends supporting the vehicle body through a suspension system, so that a unitary axle is typically fitted with non-independent suspensions; the axle can also be of a disconnected type, like two umbrellas are inserted at the two sides of the vehicle body, and then the vehicle body is supported by the suspension system respectively, so that the disconnected type axle is matched with the independent suspension.
The spindle nose and the bearing gauge connected with the wheel in the existing axle assembly are large in size, the weight of the spindle nose is increased to a certain extent, the energy consumption of an automobile is further increased, and the transportation cost is high.
The utility model content is as follows:
in order to solve the problems and overcome the defects of the prior art, the utility model provides the low flat axle assembly which is simple in structure, high in strength and small in self weight.
In order to achieve the purpose, the utility model provides a low flat plate axle assembly, which comprises a hollow axle tube, wherein hubs are arranged at two ends of the axle tube in a rotating manner, and hub covers are arranged at the outer sides of the hubs; the outer rings of the inner sides of the two hubs are fixedly provided with brake shoes through bolts, the two brake shoes are connected with cam shafts, the lower part of the shaft tube is provided with two adjusting arms, and one ends of the two cam shafts are respectively connected with the two adjusting arms in a matched manner; the central siphon includes outer wall and inner wall, and the cross section of outer wall is circular, and the cross section of inner wall is the gear form, and central siphon inside is provided with the triangular tube, and three arriss of triangular tube all with inner wall fixed connection.
Further, the cross section of the inner wall is arranged to be saw-toothed.
Furthermore, a tire supporting reinforcing rib is arranged on the wheel hub.
Furthermore, a dustproof cover is arranged on the outer side of the hub cover.
Further, the hub cap is connected with the hub through screws.
The utility model has the beneficial effects that:
the low flat plate axle assembly provided by the utility model has the advantages of simple structure, high strength and small self weight.
The central siphon is hollow structure, and inner wall and outer wall structure are different, and the inner wall is gear form or cockscomb structure, has bigger structural strength according to the structure principle, and central siphon inside still is connected with the triangular tube, further plays the effect that increases structural strength.
