Now the front suspension. Traverse it rotate on axes which are inserted into the tubes welded to the power frame “Hummingbird.” The ends of the traverse are ball joints. In them is fixed the piston rod of front shock absorbers from motorcycles M-105, M-106. The upper ends of the shock absorbers are bolted to brackets on the arcs security.
For rods above ball joints worn pivot bushings, welded with axles of the wheels and the swing arm, and fixed therein through bolts.
From heads of rotary levers are thrust to the longitudinal axis of autoroller where the steering column shaft, passed through the lid of the air duct channel. The steering column is folded to reduce the overall height of the machine, which is important when storing it in small spaces.
Rims homemade cast aluminum. Their sizes are the same as we drive the wheels of the rear axle.
The basis of the rear axle is a steel axle on which the brake drum from motorcycle M-105 and four bearings in a housing. The drum is put on the collet.

1 — absorber, 2 — swivel bushing, 3 — bolt damper, 4 — Travers, a 5 ball joint 6 — axis suspension, 7 — node suspension, 8 — pivot arm, 9 — disc wheels 10, 12 — bearing, 11 — wheel, 13 — bus-25 3,5X5.
Fig. 5. Rear axle:
1 — bus-25 3,5X5, 2 — disc wheels, 3 — puck Ø40Х16Х4 mm, 4 — collet wheel 5 — bearing No. 304 (4 PCs), 6 — axis, 7— brake lever, 8 — sprocket drum, 9 — collet reel, 10 — bolt M8X1. 25 (4 PCs), 11 — thrust, 12 — fixing unit. 13 — stressing the brake cable. 14 — cable 15 — knots of the suspension bridge, 16 — transverse cross member, 17 — longitudinal traverse of 18 attachment points of the rear dampers.
The force from the motor shaft is transmitted through a chain, draped over the sprocket drum. Brake drum; it is driven by a cable from the pedal installed on the floor.
Suspended bridge four nodes. Two of them are located on the transverse traverse and bonded with the body “heat” in the bottom. Other nodes on the longitudinal traverse. These are mounted rear shock absorbers from motorcycles M-105, M-106, which transmit the efforts to the upper part of the body of autoroller where there are corresponding eyelets fastening.
Takaw suspension bridge promotes reliable torque transmission from the engine, effective braking and a soft ride.
I must say that “Hummingbird” is generally a very convenient and easy to handle. If necessary, the level of comfort can be improved providing autoroller cloth top and windshield.
