To reach 12000rpm, high-grade high-powered car engine peak speed also can reach 7000rpm), engine crankshaft runs up
Bent axle rubber torsional vibration damper inertia rings can be produced the biggest inertia force, simultaneously because vehicle traveling process often occurs urgency
The situations such as acceleration or brake hard, produce the biggest torsion to the inertia rings of bent axle rubber torsional vibration damper, and this just requires bent axle
The damping rubber of rubber torsional vibration damper to have enough adhesive strengths.
The bent axle rubber torsional vibration damper commonly used on domestic market is owing to being limited by product size and weight
System, generally the bond area of damping rubber is less, and inertia rings and wheel hub are all smooth with damping rubber abutting edge
Surface, bonding insecure, adhesive strength is low.When vehicle motor high speed rotating and suddenly acceleration or brake hard, because inertia
Effect, inertia rings produces the biggest rotary torsion to damping rubber.When moment of torsion is more than rubber adhesive strength, will result in torsion
Resistance of shock absorber rubber adhesive failure (degumming), inertia rings and wheel hub generation relative motion, cause bent axle rubber torsional vibration damper
Disequilibrium and cushioning effect, when causing electromotor to work, vibration and noise increase.Simultaneously because bent axle rubber torsional vibration damper
Adhesive failure cisco unity malfunction, damping rubber loses damping action, and inertia torsion all acts on the bent axle of rigidity, makes song
Axle fatigue strength reduces appearance be full of cracks, ultimately results in crankshaft breakdown.More seriously, after rubber adhesive failure, inertia rings is at height
Disengaging with wheel hub when speed rotates, inertia rings is damaged after being thrown out of under the effect of powerful inertia power other parts of electromotor,
And likely inertia rings batters down bonnet and flies out outside car, threatens the safety of other vehicle and personnel, brings the biggest safety to driving
Hidden danger.
