Description

Electric motorcycle car wheel hub motor shell chamber device that leaks hunting

Technical Field

The utility model relates to a check out test set, concretely relates to check out test set of electric motorcycle car wheel hub gas tightness.

Background

With the development of the motorcycle market and development technology, electric motorcycles are used, and the motor replaces an engine to become a driving unit. Because the motor and the hub are combined together, compared with the hub of a conventional motorcycle, the hub of the electric motorcycle (shown in figure 1) needs to ensure that the hub is airtight except for the tire mounting position of a rim, and the position (a motor shell cavity) for mounting the motor in the middle needs to be airtight after assembly so as to prevent water leakage and potential safety hazards. Because the hub air leakage condition of the conventional wheel hub does not need to be detected, the special tool for the conventional wheel hub air tightness detection equipment cannot meet the requirement of leakage detection of a motor shell cavity. In addition, due to the shielding of other equipment structures of the electric motorcycle, even if the hub leaks, the hub cannot be observed, so that a new detection device needs to be designed for detecting the air leakage of the motor shell cavity.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: a device for detecting the air leakage condition of a hub motor shell cavity of an electric motorcycle is provided.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides an electric motorcycle car in-wheel motor shell chamber device that leaks hunting, includes first frock, second frock and center pin, first frock and second frock are installed on the center pin, the dead eye of motor shell chamber one end can be sealed to first frock, the other end in motor shell chamber can be sealed to the second frock, the second frock is equipped with the pressure port.

Leak hunting device, by the other end in motor housing chamber inserts motor housing chamber, in the sealed dead eye of first frock, the other end in the sealed motor housing chamber of second frock. And then, pressurizing and maintaining the pressure of the motor shell cavity through the pressurizing port, placing the hub into the water tank, and observing whether the leakage phenomenon exists.

Leak hunting device, can once seal in place convenient operation to in-wheel motor shell chamber front and back end.

Detailed Description

Referring to fig. 2, the leakage detection device for the hub motor shell cavity of the electric motorcycle comprises a first tool 10, a second tool 20 and a central shaft 30, wherein the first tool and the second tool are installed on the central shaft, the first tool can seal a bearing hole 51 at one end of the motor shell cavity 50, the second tool can seal the other end of the motor shell cavity, and the second tool is provided with a pressurizing port 21.

As shown in fig. 4, the leak detector 100 is pressed into the motor housing cavity 50 of the hub, the first fixture 10 seals the bearing hole by friction between the outer edge of the first fixture and the central bearing hole 51 of the hub, and the second fixture 20 simultaneously seals the motor housing cavity by friction between the outer edge of the second fixture and the wall of the motor housing cavity. Thus, the leak detection device seals the motor housing cavity 50 once. Then, compressed air is injected into the motor shell cavity 50 through the pressurizing port 21, the hub 500 is placed into the test water tank 60, and due to the fact that the two ends are sealed, if the hub has defects such as casting air holes, air bubbles can seep out of the surface of the hub, and the fact that the air tightness of the motor shell cavity of the test product is poor is indicated. Because the pressurization pressure of the motor casing cavity 50 is smaller, the resistance of the leakage detection device sliding out of the motor casing cavity after sealing is far greater than the pressure in the pressurized motor casing cavity.

As shown in fig. 2, as a structural design, a first annular groove is formed on the periphery of the first tool 10, and a first seal ring 11 is fitted therein, and a second annular groove is formed on the periphery of the second tool 20, and a second seal ring 22 is fitted therein. The first tool 10 seals the bearing hole by using friction between the first sealing ring and the central bearing hole 51 of the hub, and the second tool 20 seals the motor shell cavity by using friction between the second sealing ring and the wall of the motor shell cavity.

One end of the central shaft 30 is provided with a handle 31, which is convenient for an operator to match the leakage detection device into the motor casing cavity 50 and to take out the leakage detection device from the motor casing cavity.

Referring to fig. 2 and 3, the central shaft 30 is provided with a first journal 32, a second journal 33, a first threaded section 34 and a second threaded section 35, the first tool 10 is fitted on the first journal, the second tool 20 is fitted on the second journal, the first nut 36 is screwed on the first threaded section to fix the first tool, and the second nut 37 is screwed on the second threaded section to fix the second tool. So design, the installation and the dismantlement of whole device that leaks hunting are convenient, and wherein, handle 31 can be fixed in the one end of center pin 30 through threaded connection spare after the installation of second frock 20 is accomplished.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
