Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model made concrete introduction.
Electric automobile suspension of the present utility model includes: front suspension and rear suspension system.
One, front suspension
With reference to Fig. 1, front suspension includes: front torsion-bar spring 1, secondary piston amortisseur 2, system
Dynamic device 3 and swing arm 4.
Front torsion-bar spring 1 set is locked in the outside of secondary piston amortisseur 2.
The upper end of secondary piston amortisseur 2 is connected with front baffle assembly, and lower end is fixed on brake 3
Knuckle on.
Brake 3 is connected with electric automobile front-wheel, and its side is connected with one end of swing arm 4.
The other end of swing arm 4 is connected with front floor framework assembly.
Two, rear suspension system
With reference to Fig. 1, rear suspension system includes: towing arm 5, rear torsion-bar spring 6, spring retainer
Block 7 and back piston amortisseur 8.
The two ends of towing arm 5 are connected with floor after vehicle body.
One end of rear torsion-bar spring 6 is fixed on one end of towing arm 5, and the other end is fixed on rear ground
On framework assembly.
Spring retainer block 7 set is locked in the inner side of rear torsion-bar spring 6, its one end and rear torsion-bar spring
One end of 6 is together fixed on rear floor frame assembly.Spring retainer block 7 is in order to turn round after protecting
Bar spring 6, prevents it from when being subject to exceed the enormous impact power of its tolerance range, excessive deformation occurring
And cannot resile.
One end of back piston amortisseur 8 is fixed on one end of towing arm 5, the other end and rear floor
Frame assembly is connected.
