Abstract

The utility model discloses a special tricycle wheel hub motor, fit the spindle that end cover and motor main part middle part set up in the motor main part including motor main part, lid, the spindle runs through the end cover, and stretch out outside the end cover, the motor main part overcoat is equipped with the casing, the wheel hub of tricycle is regarded as to the casing, end cover fixed mounting is on the casing. The utility model discloses because the motor main part seals completely in the sealed space that casing and end cover formed, just the casing realizes the integrated design as the wheel hub of tricycle to reduce motor repeated assembly, screw smooth silk, the connecting portion leakproofness that leads to because of the tire assembly poor, motor performance unstable and the easy scheduling problem of intaking.

Description

Special tricycle hub motor

Technical Field

The utility model relates to an electric motor car motor field, concretely relates to special type tricycle in-wheel motor.

Background

The motor directly driving the wheel hub to rotate is a wheel hub motor, is widely applied to electric vehicles and other transmission mechanisms, and currently, the structure of domestic electric tricycles generally adopts a rear axle differential motor mode, so that the electric tricycles cannot normally run due to the fact that motor faults easily occur. Afterwards the special type tricycle adopts three drive power structures, and the three wheel of electric motor car is the motor promptly, and the vehicle power of this kind of structure is more powerful, and avoids the condition because of the nest of lying prone to the motor trouble appearance, has effectively reduced the use risk. However, the hub motor of the motor is of a split structure, and the motor is easy to feed water under the relatively severe using condition, so that the service life of the motor is shortened, and the current practical requirements cannot be completely met.

Disclosure of Invention

To the above, an object of the utility model is to provide a special type tricycle in-wheel motor avoids the motor to intake under adverse circumstances to improve the reliability in utilization of motor, reduce the fault rate, improve the life of motor.

In order to achieve the above purpose, the utility model provides a technical scheme is:

the special tricycle hub motor comprises a motor main body, an end cover covering the motor main body and a motor shaft arranged in the middle of the motor main body, wherein the motor shaft penetrates through the end cover and extends out of the end cover, a shell is sleeved outside the motor main body, and the shell is used as a tricycle hub.

Preferably, one end of the crankshaft extending out of the end cover is connected with an outgoing line.

Preferably, the shell is made of aluminum alloy die-casting.

Preferably, the end cap is fixedly mounted on the housing.

Preferably, the motor main body includes a stator and a rotor, which generate a power source to rotate the housing.

The utility model has the advantages that: the utility model discloses because the motor main part overcoat is equipped with the casing, and end cover fixed mounting is on the casing to seal the motor main part totally in the sealed space that casing and end cover formed, just the casing realizes the integrated design as the wheel hub of tricycle, thereby reduces motor repetitive assembly, screw smooth silk, the connecting portion leakproofness that leads to because of the tire assembly poor, motor performance unstable and the easy scheduling problem of intaking.

The present invention will be further explained with reference to the drawings and the embodiments.

Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1 and 2, a special tricycle hub motor includes a motor main body 1, an end cover 2 covering the motor main body 1, and a crankshaft 3 disposed in the middle of the motor main body 1, wherein the crankshaft 3 penetrates through the end cover 2 and extends out of the end cover 2, a housing 4 is sleeved outside the motor main body 1, and the housing 4 is used as a tricycle hub, that is, a shell of the motor is also a vehicle hub.

In this embodiment, an end of the machine shaft 3 extending out of the end cover 2 is connected with a lead-out wire 5.

In this embodiment, the material of the housing 4 is an aluminum alloy die casting, specifically, an ADC12 aluminum alloy die casting.

In the present embodiment, the end cap 2 is fixedly mounted on the housing 4, so that the motor main body 1 is completely sealed in the sealed space formed by the end cap 2 and the housing 4.

Further, the motor main body 1 includes a stator and a rotor that generate a power source to rotate the housing 4, that is, to rotate a hub of a vehicle.

Variations and modifications to the above-described embodiments may occur to those skilled in the art, in light of the above teachings and teachings.
