Abstract
The utility model aims at providing a powertrain of an electrocar, wherein the powertrain has small occupied area and convenient installation. The powertrain of the electrocar comprises a motor, a transmission wheel and a differential mechanism, wherein the motor is used for driving an automobile; the transmission wheel is used for transmitting the motor power to a driving wheel; the key point isthat the transmission wheel and the differential mechanism are arranged in a shell fixed with the motor; the shaft of the differential mechanism extends out of the shell; the transmission wheel comprises a drive wheel and a driven wheel; the drive wheel is coaxially arranged with the motor, and the driven wheel is coaxially arranged with the differential mechanism; and the drive wheel and the driven wheel can drive directly or can drive by a speed reducer. In the utility model, the motor, the transmission wheel and the speed reducer are combined together, the transmission wheel and the speed reducer are arranged in the shell, and the motor power can be transmitted onto the driving wheel by passing the drive wheel, the driven wheel and the differential mechanism sequentially; moreover, thepowertrain has simple and compact structure as well as convenient and reliable installation, and can be applicable to the electrocar with strict space requirement.
Description
Technical field
The utility model belongs to auto parts and components manufacturing technology field, specially refers to the engine installation of electronlmobil.
Background technology
Along with the consumption of global petroleum-based energy is more and more, environment goes from bad to worse, and leans on the electronlmobil of power-actuated environmental protection to come into one's own day by day, and its development is also more and more faster.At present, the drive motor of battery-driven car and speed reduction gearing are made separately mostly, utilize coupler, power-transfer clutch to connect, and it is bigger to take up room, and difficulty is installed.
The utility model content
The purpose of this utility model is to propose a kind of power assembly of electric automobile little, easy for installation that takes up room.
Power assembly of electric automobile of the present utility model, comprise motor that drives automobile and power wheel and the diff that motor power is delivered to drive wheel, key is that described power wheel and diff are arranged in the housing that is fixed together with motor, the shaft extension of diff goes out housing, described power wheel comprises and the driving wheel of motor coaxle and the flower wheel coaxial with diff, described driving wheel and flower wheel through-coupling or pass through the retarder transmission.
The utility model integrates motor, power wheel and retarder, and power wheel and retarder be arranged in the housing, the power of motor is delivered on the drive wheel through driving wheel, flower wheel and diff successively, has reduced arrangement space, installs also convenient.
Transmission is more smooth-going, moment of torsion is bigger in order to make, be provided with the retarder that constitutes by the different ratio wheel of two coaxial radiuses between the driving wheel of described power wheel and the flower wheel, described retarder is fixed in the housing, and two ratio wheel passes through the mode transmission of belt or gear mesh respectively with driving wheel and flower wheel.
For preventing that the lubricating oil in the housing from entering motor by motor shaft, is provided with the isolating seal device between described housing and the motor.
Described housing is made of the polylith housing parts of aluminium alloy compression casting, is bolted to connection between the described housing parts, can reduce the weight of housing like this, and convenient the installation.
Power assembly of electric automobile of the present utility model is simple in structure, compact, and is easy for installation, reliable, is suitable for the electronlmobil to the space requirement strictness.
