Abstract
The utility model discloses an electric vehicle transmission's clutch overcoat, including the overcoat body, this internally has a cavity with clutch pawl wheel matched with the overcoat, and overcoat body center is equipped with the shaft hole, and follow the axial in the shaft hole in and be equipped with the keyway, the around the shaft hole is equipped with the pin shaft matched with through -hole that takes turns to with the clutch bolt on the overcoat body. Compared with the prior art, the utility model discloses a form the clutch with clutch bolt wheel and clutch pawl wheel post assembling when the clutch overcoat uses, in the electric motor car uses clutch bolt wheel can be rapidly with clutch pawl wheel separation and closed, can make and shift gears rapidly, simple convenient and fast starts to walk.
Description
Technical field
The utility model relates to the clutch field of electric vehicle transmission, particularly a kind of clutch outer of electric vehicle transmission.
Background technology
At present, the electric vehicle motor that market produces is by electronic controller to reach stepless change, and its rotating speed from zero to rated value, can be compared with engine throttle speed change, and the speed change of motor is more steady.But the method adopting electronic controller to carry out speed change has very large deficiency: in climbing with when loading, the continuous increase by electric current during machine operation increases torque, changes hill climbing ability with this.Therefore, torque big current is just large, and the Driving Torque of motor is little, and consumption of current is large, and the ability that continues shortens widely.
The wheel hub motor of sun and planet gear and battery-driven car integrates by some producers, carries out speed change by sun and planet gear.But when speed change, since needing to make disengaging of clutch, complete gear shift operation.But existing battery-driven car power-transfer clutch is due to its structure problem, often occurring shifts gears has some setbacks or the difficult problem that starts to walk.
Summary of the invention
The purpose of this utility model is the deficiency that will solve prior art problem, provides a kind of clutch outer of electric vehicle transmission.
For achieving the above object, the utility model is implemented according to following technical scheme:
A kind of clutch outer of electric vehicle transmission, comprise coat body, the cavity matched with power-transfer clutch ratchet wheel is had in coat body, coat body center is provided with axis hole, be provided with keyway vertically in axis hole, described coat body is provided with around axis hole the through hole that the bolt axle of taking turns with power-transfer clutch latch matches.
Compared with prior art, when clutch outer of the present utility model uses and power-transfer clutch latch is taken turns and clutch claw take turns assemble after form power-transfer clutch, in battery-driven car uses, power-transfer clutch latch wheel can promptly be separated with power-transfer clutch ratchet wheel and close, and gearshift can be made rapid, start to walk fast simple and convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cutaway view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, is used for explaining the utility model in the illustrative examples of this utility model and explanation, but not as to restriction of the present utility model.
The clutch outer of a kind of electric vehicle transmission as shown in Figure 1 and Figure 2, comprises coat body 1, has the cavity matched with power-transfer clutch ratchet wheel in coat body 1
5, coat body 1 center is provided with axis hole 2, is provided with keyway 3 vertically in axis hole 2, and described coat body 1 is provided with around axis hole 2 through hole 4 that the bolt axle of taking turns with power-transfer clutch latch matches.
During assembling, the bolt axle of being taken turns by power-transfer clutch latch is inserted in the annular through-hole on power-transfer clutch ratchet wheel, again clutch outer is nested with the opposite side at power-transfer clutch ratchet wheel, bolt axle on the power-transfer clutch latch wheel of the annular through-hole on power-transfer clutch ratchet wheel just in time matches with through hole 4, can form power-transfer clutch.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
