Position device fixed bracket (49), the second restorer fixed bracket (50), restorer spring (51), release link (52) and lead (53)；
The slip coupling (48) slidably reciprocates in right axle shaft output shaft (32) and the spline on reducer output shaft (45)；Institute
It states the first restorer fixed bracket (49) and connects firmly slip coupling (48)；First restorer fixed bracket (49), second are answered
Release link (52) are connected between position device fixed bracket (50)；Release link (52) side surrounding restorer spring (51)；
Second restorer fixed bracket (50) is fixed on reducer output shaft (45), presses switch button and lead (53) is pulled to make
Slip coupling (48) sliding is obtained, to realize the disconnection of right axle shaft output shaft (32) Yu reducer output shaft (45), is restored out
Button is closed, since the elastic force of restorer spring (51) pushes the first restorer fixed bracket (49) to move right, to push cunning
Dynamic shaft coupling (48) reset, so that right axle shaft output shaft (32) is connected with reducer output shaft (45).
8. motor rear axle drive system as described in claim 1, it is characterised in that: in the wheel and braking system (3)
Braking system include brake disks (54), the first shoe plate support plate (55), shoe brake (56), shoe plate branch board shaft (57), hoof
Bobbin baffle (58), the second shoe plate support plate (59), brake rocker arm axis (60), brake shoe retracting spring (61), brake rocker arm
(62), automotive wheel (63) and Wheel set bolt hole (64)；The brake disks (54) are solid by brake disc mounting hole (36)
It is scheduled on left half axle shell (6) and retarder output housing (9)；The first shoe plate support plate (55) passes through shoe plate branch board shaft
(57) it is connected with brake disks (54), and the first shoe plate support plate (55) turns on brake disks (54) around shoe plate branch board shaft (57)
It is dynamic；Shoe shaft baffle (58) connects two shoe plate branch board shafts (57), limits the rotational angle of the first shoe plate support plate (55)；It is described
Second shoe plate support plate (59) is connected firmly with the first shoe plate support plate (55)；The brake rocker arm axis (60) and brake disks (54) axis
Diameter cooperation；The brake shoe retracting spring (61) is connected to the both ends of two panels the first shoe plate support plate (55) to guarantee
The reset of one shoe plate support plate (55)；The brake rocker arm (62) connects firmly with brake rocker arm axis (60)；The shoe brake (56)
It connects firmly in the first shoe plate support plate (55), shoe brake (56) and hub for vehicle wheel when the rotation of the first shoe plate support plate (55)
(37) inside phase mutual friction is so that automotive wheel (63) stops operating to realize braking, the Wheel set bolt hole (64)
It is arranged on automotive wheel (63).
