Abstract

The utility model discloses a normal-reverse two-gearshift speed variable motor reduction box for an electric car. The utility model solves the technical problem that the a motor can be better fitted in a complicated load condition when a car runs The utility model comprises a high speed gear 1, a low speed gear 2, overdrive clutches 3, 4, a driven shaft 5 a motor axle head gear 6 and low speed intermediate gears 8, 9, wherein the high speed gear and the low speed gear are respectively connected with the driven shaft in one-way wheel spin through the overdrive clutches. The two low speed intermediate gears are connected with shaft key pins in rigid connection. One side of the motor axle head gear 6 is engaged with the high speed gear, and the other side is engaged with the low speed intermediate gear 9. The low speed intermediate gear 8 is engaged with the low speed gear 2. The utility model is characterized in that when the motor normally rotates, the high speed gear is engaged with the driven shaft and rotates, when the motor reversely rotates, the low speed gear is engaged with the driven shaft and rotates. The utility model can increase the climbing capacity of the electric car, electricity can be saved and the service life of a battery can be extended.

Description

Two grades of speed-variable motor speed reduceres of electric vehicle clockwise and anticlockwise
Technical field:
The utility model relates to particularly electric bicycle motor drive mechanism device of electric motor car.
Background technique
Have the electric vehicle motor now and have only speed shelves, cause electric motor car to start to walk in the process of moving to quicken like this and climbing etc. increases moment of torsion by increasing electric current when loading greatly fully, and this not only has injury to motor, and is just bigger to the storage battery injury.
Summary of the invention
The purpose of this utility model is to provide a kind of and is more suitable for loading condiction complicated in the vehicle driving process, and variable speed operation electric vehicle motor deceleration case easily.
Technological scheme
The purpose of this utility model is to adopt following technological scheme to realize: the utility model is made up of motor shaft head gear, high speed gear, bootom gear, two bottom gear intermediate gears and two free wheel devicees.It is characterized in that in the middle of bootom gear centre and the high speed gear free wheel device being housed respectively.Its motor shaft head direct geared driven high-speed shelves gear when motor just changes, this moment, the free wheel device at high speed gear center was bitten the driven shaft rotation.And bootom gear trackslips on driven shaft, and its motor shaft head gear is through bottom gear intermediate gear transmission bootom gear when motor reverses, and this moment, bootom gear center free wheel device was bitten the driven shaft rotation, and high speed gear trackslips on driven shaft.
The utility model compared with prior art have speed change convenient, effectively improve the advantage in electric motor car accelerating ability from standstill and grade ability, power saving, prolongation electric motor car mileages of continuation and storage battery working life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Figure high speed shelves gear 1, bootom gear 2, high speed gear's center free wheel device 3, bootom gear center free wheel device 4, driven shaft 5, motor shaft head gear 6, bottom gear intermediate gear shaft 7, bottom gear intermediate gear 8, bottom gear intermediate gear 9.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, as shown in the figure, the utility model is two grades of speed-variable motor speed reduceres of a kind of electric vehicle clockwise and anticlockwise, it is by motor shaft head gear 6, high speed gear 1, bootom gear 2, high speed gear's center free wheel device 3, bootom gear center free wheel device 4, driven shaft 5, bottom gear intermediate gear 8 and 9 is formed.Driven shaft 5, motor shaft head gear 6 and 7 three central line of bottom gear intermediate gear shaft are arranged (arrangement can not form straight line yet); But motor shaft head gear 6 exterior edge faces are concordant with high speed gear 1 exterior edge face, and high speed gear 1 and bootom gear 2 are all on driven shaft, and Gear center is connected with unidirectional the trackslipping of driven shaft with 4 by free wheel device 3 respectively; Bottom gear intermediate gear 8 and 9 and the intermediate gear shaft key pin be rigidly connected; Motor shaft head gear 6 one sides and high speed gear's 1 engagement, opposite side and 9 engagements of bottom gear intermediate gear, bottom gear intermediate gear 8 and bootom gear 2 engagements.Motor shaft head gear 6 direct driven high-speed shelves gears 1 when motor just changes, high speed gear's center free wheel device 3 is bitten driven shaft 5 rotations simultaneously.And bootom gear trackslips on driven shaft, motor shaft head gear 6 is through bottom gear intermediate gear 8 and 9 transmission bootom gears 2 when motor reverses, bootom gear center free wheel device is bitten driven shaft 5 rotations simultaneously, and high speed gear trackslips on driven shaft, thereby realizes the purpose of two grades of speed changes.Because the motor clockwise and anticlockwise only need change circuit, therefore when variable speed operation, only need press a push-button switch and can operate, very convenient.
