Abstract
The utility model provides a pure electric vehicles's novel power transmission mechanism, includes: transmission housing, be fixed in transmission housing one end the gearbox, be fixed in the transmission housing other end driving motor, set up clutch pressure plate and the flywheel in transmission housing and set up in transmission housing and be located the clutch driven plate between clutch pressure plate and the flywheel. Since at flywheel internally mounted the bearing frame, with back in the bearing that assembles in the bearing frame of gearbox II, both saved installation space, solved the gearbox again because of the gearbox abnormal sound, the transmission that the result in phenomenon such as not smooth -going of beating. Simultaneously, I cooperation transmission housing on the bearing has been designed to the fixed completion of bearing I assurance to driving motor's output shaft ride comfort in the shaft coupling outside. The problem of because of the output shaft phenomenons such as the clutch abnormal sound that brings, transmission efficiency is low, the separation and reunion separation is not thorough of beating, also because of the flywheel mass is big, inertia causes output shaft self intensity reliability greatly is solved.
Description
Technical field
This utility model is related to a kind of new type power drive mechanism of pure electric automobile.
Background technology
At present, in pure electric automobile, the drive pattern of motor+clutch+change speed gear box is greatly employed, is led to
Often motor one end shaft coupling connects flywheel, and flywheel to increase inertia, and usual quality is larger, for motor output shaft comes
Say, cantilever is long bounce easily occur so as to result in motor output shaft, and then cause the unstable situation of power output, and
Change speed gear box side also causes power output unstable because of the bounce of an axle.Because clutch end motor and power are transmitted
The end axle of change speed gear box one is beated and result in the defect of the following aspects：
1st, motor, flywheel, change speed gear box and clutch have abnormal sound；
2nd, power transmission line deviates, and clutch release travel is excessive or too small；
3rd, when high-speed cruising or big torque are exported, gearbox gear engagement is abnormal, " beating tooth " even gear shaft occurs and becomes
Weakened and emaciated body is bad；
4th, transmission efficiency is reduced, and car load resistance is excessive, causes car load economic performance to decline.
The content of the invention
This utility model is in order to overcome the shortcomings of above technology, there is provided one kind prevents output shaft bounce from causing clutch different
The new type power drive mechanism of the low pure electric automobile of sound, transmission efficiency.
This utility model overcomes the technical scheme that its technical problem is adopted to be：
A kind of new type power drive mechanism of pure electric automobile, including：Gear box casing, it is fixed on gear box casing one end
Change speed gear box, be fixed on the motor of the gear box casing other end, the clutch compressing disc being arranged in transmission housing body and fly
Take turns and be arranged in transmission housing body and the clutch driven plate between clutch compressing disc and flywheel, shaft coupling passes through axle
Hold I rotation to be installed in transmission housing body, its one end is coaxially connected with flywheel by threaded fastener, its other end is by inside
The internal spline of setting is coaxially connected with the splined shaft of motor, and bearing block is coaxially installed on inside flywheel, in the bearing block
Bearing II is fixed with, an axle of change speed gear box is plugged in the endoporus of bearing II, and the clutch driven plate is set in change speed gear box
On the splined shaft of one axle.
For the ease of the axial limiting of bearing I, also including the bearing snap spring I being fastened on shaft coupling, outside the bearing I
Side contacts with the medial extremity of bearing snap spring I.
For the ease of the axial limiting of bearing II, also including the bearing snap spring II being fastened in bearing block, the bearing II
Outboard end contact with the medial extremity of bearing snap spring II.
The beneficial effects of the utility model are：Due to being mounted with bearing block inside flywheel, an axle of change speed gear box is assembled
After in bearing II in bearing block, both saved installing space, solve again change speed gear box because an axle is beated caused speed change
The phenomenons such as case abnormal sound, transmission irregularity, improve the operating safety factor of drive system.Driving motor output shaft passes through shaft coupling
It is connected with flywheel, is adapted to the installation requirements of the motor of the flywheel matching different size of different size.Meanwhile, in connection
Axle device outside devises bearing I and coordinates fixation of the gear box casing to bearing I to complete the output shaft ride comfort to motor
Ensure.Solve that the clutch abnormal sound because output shaft bounce brings, transmission efficiency be low, clutch separates the phenomenon such as not thorough,
Solve the problems, such as to cause motor output shaft self-strength reliability because flywheel mass is big, rotary inertia is big.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, the 1. bearing I 7. of 2. clutch compressing disc of change speed gear box, 3. clutch driven plate, 4. flywheel, 5. shaft coupling 6.
The bearing block of II 11. gear box casing of motor 8. bearing snap spring, I 9. bearing snap spring, II 10. bearing 12..
Specific embodiment
Below in conjunction with the accompanying drawings 1 pair of this utility model is described further.
A kind of new type power drive mechanism of pure electric automobile, including：Gear box casing 11, it is fixed on gear box casing 11
The change speed gear box 1 of one end, the motor 7 for being fixed on the other end of gear box casing 11, the clutch being arranged in gear box casing 11
Device platen 2 and flywheel 4 and be arranged in gear box casing 11 and the clutch between clutch compressing disc 2 and flywheel 4 from
Moving plate 3, shaft coupling 5 is rotated by bearing I 6 and is installed in gear box casing 11, and its one end is by threaded fastener and flywheel 4
Coaxially connected, its other end is coaxially connected with the splined shaft of motor 7 by the internal internal spline for arranging, and bearing block 12 is coaxial
It is installed on inside flywheel 4, bearing II 10 is fixed with bearing block 12, an axle of change speed gear box 1 is plugged in the endoporus of bearing II 10
In, clutch driven plate 3 is set on the splined shaft of an axle of change speed gear box 1.Due to being mounted with bearing block 12 inside flywheel 4,
After in the bearing II 10 that one axle of change speed gear box 1 is assembled in bearing block 12, installing space was both saved, speed change had been solved again
