Bounce is larger, and the common drum brake being connected with drive shaft can not ensure the circular runout near connection end.Therefore, having must
Design rearmounted rear-guard electric car transmission connecting structure, rearmounted rear-guard pattern electric car configuration under and trailing wheel be drum brake
When can ensure power by drive shaft to wheel power transmission, connection and support.
The content of the invention
The invention discloses rearmounted rear-guard electric car transmission connecting structure, under the configuration of rearmounted rear-guard pattern electric car and after
Power can be ensured by the power transmission of drive shaft to wheel, connection and support by taking turns during for drum brake.
Rearmounted rear-guard electric car transmission connecting structure disclosed by the invention, including：Drive shaft, universal joint, bearing block, axle
Hold, rotating hub flange and drum brake；
Described drive shaft one end is used to be connected with rear-guard electric car differential mechanism, and the other end is fixedly connected with universal joint input；
The universal ball cage output end extends spline output end, the spline output end and rotating hub flange boss
Internal splined hole fixes matching；
The bearing press mounting is between rotating hub flange boss outer rim and bearing block inner ring；
Drum brake back-plate is fixedly connected with the bearing seat, and drum brake brake drum is fixed with rotating hub flange ring flange to be connected
Connect.
Further, in addition to rear axle support, the rear axle support is used to be arranged in left and right vehicle wheel side, for passing through rear axle
Left and right is connected；Rear axle support pedestal, which maintains an equal level and extended from its side with ground, circumferentially surrounds universal ball cage output end
Bearing disk body；The bearing disk body card props up bearing block side and is secured to connection；Spline output end is from bearing disk body
Centre bore extends.
Further, bearing block circumferential edge stretches out radial direction outer lug boss, and bearing disk body card props up the extension of bearing block side
Go out axial boss and prop up radial direction outer lug boss side, drum brake back-plate props up radial direction outer lug boss opposite side, passes through bolt
Three is fixedly connected also cross drum brake back-plate, radial direction outer lug boss and axial boss.
Further, the spline output end extends internal splined hole and screws in clamp nut extending one end.
Further, in addition to dust cover, the sky that the dust cover is covered between bearing block and rotating hub flange boss face
Between gap.
Further, fixation steel plate spring on rear axle support pedestal, described leaf spring two is connected with electric car car body.
Advantageous effects of the present invention are：The present invention can realize moment of torsion and power by drive shaft to wheel power transmission,
Connection and support.Rear drive shaft is interrupted into the drive shaft end for universal-joint, being connected again with rotating hub flange by universal joint can
To meet circular runout demand of the power in rear drive system；Drum brake be arranged on rotating hub flange ring flange and bearing block it
Between realize effective connection of drive shaft and drum brake, Space configuration is compact；Rear axle support side is connected with vehicle body, another
Extend branch attic base and prop up bearing block and can ensure firmly installing property of bearing block, NVH with the circumferentially fixed installation of bearing block in side
Energy（Because this local circular runout is obvious）；Bearing block overhangs radial direction outer lug boss, and radial direction outer lug boss side props up branch attic base
The axial boss in body disc face, opposite side prop up drum brake back-plate, unified through fixed installation by bolt, realize
The compact stability that three is fixedly mounted.
Brief description of the drawings
Fig. 1 is rearmounted rear-guard electric car transmission connecting structure schematic diagram；
Fig. 2 is rear axle support and rear axle connecting assembly figure.
Embodiment：
The invention will be further described with reference to the accompanying drawings and detailed description.
Referring to Fig. 1, rearmounted rear-guard electric car transmission connecting structure, including：Drive shaft 5, universal joint, bearing block 1, bearing 2,
Rotating hub flange 4, rear axle support 7 and drum brake.
Drive shaft one end is connected with rear-guard electric car differential mechanism, and the other end is fixedly connected with universal joint input 12.
Universal ball cage output end 13 extends spline output end 16, and spline output end 16 and rotating hub flange 4 are convex
The internal splined hole of platform fixes matching.
Bearing 1 is fitted between rotating hub flange boss outer rim and the inner ring of bearing block 1.
Drum brake back-plate 8 is fixedly connected with the bearing seat, drum brake brake drum 9 and rotating hub flange ring flange
It is fixedly connected.
Rear axle support 7 is arranged in left and right vehicle wheel side, for being connected by rear axle 17 or so.Rear axle support pedestal is held with ground
Flat, fixation steel plate spring on pedestal, leaf spring two is connected with electric car car body.Rear axle support pedestal extends from its side
Circumferentially surround the bearing disk body 6 of universal ball cage output end 13.
Bearing block circumferential edge stretches out radial direction outer lug boss 15, and bearing disk body card props up bearing block side and extends axially convex
Platform 14 props up the side of radial direction outer lug boss 15, and drum brake back-plate 8 props up the opposite side of radial direction outer lug boss 15, passes through bolt 11
Three is fixedly connected also cross drum brake back-plate, radial direction outer lug boss and axial boss.
