Description
Technical Field
The utility model relates to a tricycle technical field specifically is novel shaft type semi-axis of tricycle axle floats structure entirely.
Background
In the manufacturing process of the existing tricycle rear drive axle, a blank needs to be forged and formed for many times, the production process is complex, and the production cost is increased; and when the half shaft bears torque, the shaft body can generate a certain degree of torsion angle, and the root of the transition part between the flange and the shaft is easy to concentrate stress and generate fatigue failure due to the large diameter of the flange plate and difficult deformation, so that the service life is shortened.
Therefore, a novel shaft type half shaft full-floating structure of the tricycle axle is provided.
Disclosure of Invention
An object of the utility model is to provide a novel shaft type semi-axis of tricycle axle floats structure entirely to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: novel axle type semi-axis of tricycle axle floats structure entirely, including braking the hub, the outside of braking the hub is equipped with the arch, the taper hole has been seted up in the arch, the taper hole runs through the inner wall of braking the hub, the semi-axis is installed through the parallel key in the inside of taper hole, be equipped with the cone portion on the semi-axis, the semi-axis is close to bellied one end and installs the nut.
Preferably, the following components: and an axle housing end shaft is arranged on the outer side wall of the half shaft.
Preferably: and a bearing is arranged on the outer side wall of the axle housing end shaft.
Preferably, the following components: and a bearing seat is arranged on the outer side wall of the bearing.
Preferably: the bearing seat is connected with the brake hub through a rim bolt.
Preferably: the taper part is matched with the taper hole.
Compared with the prior art, the beneficial effects of the utility model are that: the overall thickness and diameter of the half shaft with the new structure are balanced, more torsion angles can be obtained when the half shaft is twisted by torque, the overall torsion angles are balanced, and an overlarge stress concentration area does not exist, so that the fatigue life is prolonged; in addition, the half shaft with the structure has uniform thickness, can be directly turned by round steel blanking, and has simple manufacturing process and lower manufacturing cost.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural diagram of the prior art.
In the figure: 1. a brake hub; 2. a bearing seat; 3. a bearing; 4. an axle housing end shaft; 5. a half shaft; 6. a protrusion; 7. a cone portion; 8. a nut; 9. a rim bolt; 10. a taper hole; 11. a flat bond.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Examples
Referring to fig. 1, the present invention provides a technical solution: novel shaft type semi-axis of tricycle axle floats structure entirely, including braking hub 1, the outside of braking hub 1 is equipped with arch 6, has seted up taper hole 10 on the arch 6, and taper hole 10 runs through the inner wall of braking hub 1, and semi-axis 5 is installed through flat key 11 in the inside of taper hole 10, is equipped with cone portion 7 on the semi-axis 5, and nut 8 is installed to the one end that semi-axis 5 is close to arch 6.
As shown in fig. 1: the outer side wall of the half shaft 5 is provided with an axle housing end shaft 4; through the arrangement, the installation work with external parts can be more convenient.
As shown in fig. 1: the bearing 3 is arranged on the outer side wall of the axle housing end shaft 4; through the above arrangement, the bearing seat 2 can be used more conveniently through matching with the bearing seat.
As shown in fig. 1: the outer side wall of the bearing 3 is provided with a bearing seat 2; through the arrangement, the bearing can be used more conveniently through the matching with the bearing 3.
As shown in fig. 1: the bearing seat 2 is connected with the brake hub 1 through a rim bolt 9; through the arrangement, the bearing seat 2 and the brake hub 1 can be conveniently installed.
As shown in fig. 1: the cone part 7 is matched with the taper hole 10; with the above arrangement, the half shaft 5 can be prevented from moving outward.
The working principle is as follows:
the half shaft 5 is changed from a flange type to a long shaft type, so that the left and right diameters of the half shaft 5 are not greatly different, the half shaft is suitable for blanking cold machining, the flange type can be formed only by adopting multi-sequence hot forging, the new structure obtains overall lower cost with lower weight and fewer working procedures, and the cost of the whole half shaft is reduced by 80%;
the full-floating axle half shaft 5 only bears torque, the flange disc type half shaft has larger transition stress with the connecting shaft due to larger diameter of the flange disc, the stress concentration is easier to damage when the half shaft is stressed and twisted, the thickness of the new structure half shaft 5 is uniform, a larger twisting angle can be obtained when the half shaft is stressed, and the half shaft is more difficult to damage;
because of no interference of a flange plate half shaft, the rim can be smaller according to a new structure, and the wheel rim is suitable for rims with wider varieties, especially for medium and light tricycles.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
