A kind of motor of electric motor car driving centrifugal clutching buffer includes motor and the driving box input of drive connection
Transmission shaft is provided with by Motor torque driving centrifugation between the output shaft and driving box input shaft of the motor to generate
The centrifugal clutching of Contact Transmission connection cooperation buffers connection structure so that motor is passed in startup starting stage and driving box input
Non-rigid connection is formed between moving axis and is formed between driving box input shaft after motor reaches certain rotating speed and is directly passed
Dynamic connection.
Further, the centrifugal clutching buffering connection structure includes a centrifugal friction disk and a fixed friction
Disk, wherein：The shaft core position of the centrifugal friction disk wears the output shaft end for being fixed on motor, and outer end face surrounds its axle center
It is provided with an at least centrifugal friction block, the pivot for connecting end and being located at centrifugal friction disk outer end face by one of each brake pad
It is rotatablely connected with centrifugal friction disk, the free end of each brake pad is provided with a reset for tending to further the end axle center
Spring；The shaft core position of the fixed frictional disk, which is worn, is fixed on driving box input shaft end, and whole is in cylinder peviform,
The annular sidewall of cylinder peviform surrounds the brake pad of centrifugal friction disk and remains with gap between brake pad.
Further, the centrifugal friction block uses three groups, sequentially around the axle center periphery of centrifugal friction disk outer end face etc.
Away from arrangement, the lateral wall of each centrifugal friction block is the one of the resetting spring of arc surfaced and each centrifugal friction block free end
End connect cooperation with the centrifugal friction block free end, and the other end of resetting spring connect end with adjacent centrifugal brake pad
Connection cooperation.
Compared with prior art, advantage is the utility model：
The buffer of the utility model is applied between the motor and driving box input shaft of electric vehicle, and use is centrifugal
Clutch friction structure forms non-rigid connection in the electric motor starting starting stage, its torque just drives after motor reaches certain rotating speed
Dynamic buffer realizes Contact Transmission cooperation, so as to alleviate the stall phenomenon that big resistance starts situation, protects motor, reduces consumption
Electricity and overheat, extend the service life of motor.
In order to be able to apparent understanding the utility model elaborates the tool of the utility model below with reference to description of the drawings
Body embodiment.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the enlarged diagram of the buffering of centrifugal clutching shown in A connection structure in Fig. 1.
Specific implementation mode
As shown in Figure 1, 2, motor of electric motor car described in the utility model drives centrifugal clutching buffer, includes transmission
The motor 1 and driving box 2 of connection are provided between the output shaft 11 and driving box input shaft of the motor 1 by motor
Torque drive centrifugation buffers connection structure 3 with the centrifugal clutching for generating Contact Transmission connection cooperation so that motor is starting just
Non-rigid connection is formed between stage beginning and driving box input shaft and is inputted with driving box after motor reaches certain rotating speed
Direct-drive connection is formed between transmission shaft.
Above-mentioned centrifugal clutching buffering connection structure 3 includes a centrifugal friction disk 31 and a fixed frictional disk 32,
Wherein：
The shaft core position of the centrifugal friction disk 31 wears 11 end of output shaft for being fixed on motor, and outer end face surrounds it
Axle center periphery has been placed equidistant with three groups of centrifugal friction blocks 33~35, and the lateral wall of each centrifugal friction block 33~35 is arc surfaced,
And the pivot 36 and centrifugal friction that the connection end of each brake pad 33~35 is located at centrifugal friction disk outer end face by one
Disk is rotatablely connected, and the free end of each brake pad 33~35 is provided with a resetting spring 37 for tending to further the end axle center
~39, the one end of resetting spring 37~39 connect cooperation with the centrifugal friction block free end, resetting spring 37~39 it is another
One end connect end connection cooperation with adjacent centrifugal brake pad；
The shaft core position of the fixed frictional disk 32, which is worn, is fixed on driving box input shaft end, and whole is in cylinder
Peviform, the annular sidewall of cylinder peviform surround the brake pad 33~35 of centrifugal friction disk and with 33~35 lateral wall of brake pad
Between remain with gap.
The operation principle of the utility model is as described below：
Since centrifugal clutching buffering connection structure is set between the output shaft of motor and driving box input shaft,
Motor non-action status and startup starting stage, centrifugal friction block can tend to collapse by paraxial under the pulling force effect of resetting spring
The heart is not in contact with connection at this time between centrifugal friction block and fixed frictional disk, torque is not transmitted, therefore is formed a kind of non-rigid
Property connection, buffered the impact of starting stage；After motor reaches certain rotating speed, centrifugal friction block high torque effect under,
