Description

Light medium bus independent front suspension system
Technical field
The utility model relates to the automobile suspension system technical field, furthermore relating to a kind of air bellow that adopts is the light compact car independent front suspension system of elastic element, this satisfies the chassis configuration requirement of bus and touristy coach respectively, and can be according to the client to passage width or the outer wide demand that increases or reduce in a big way of vehicle frame.
Background technology
In the running car system, all the power transmission connecting devices between vehicle frame and the vehicle bridge are generically and collectively referred to as suspension.The function of suspension is the vertical reaction on effect and the wheel on the road surface.Vertically the transmission of torque that produces of counter-force and lateral reaction and these counter-forces is to vehicle frame, and suppresses and weaken the shock and vibration that cause owing to Uneven road, with the cruising of assurance automobile.
Automotive suspension generally is divided into two big class, dependent suspension and independent suspensions.
The characteristics of dependent suspension are the two ends that left and right wheels is installed in a rigid axle, and vehicle bridge then links to each other with vehicle frame by suspension.When single wheel was beated, the opposite side wheel will inevitably be swung in the automobile Transverse plane.
It is open circuited that the characteristics of independent suspension are that vehicle bridge is made, and each sidecar wheel links to each other with vehicle frame by suspension separately.Compare independent suspension with dependent suspension following characteristics are arranged: both sides wheel independently moving is independent of each other, and can reduce body vibrations like this, reduces the nonspring carried mass of vehicle, improves the vehicle body travelling comfort.
At present, the suspension that uses on the light medium bus vehicle generally adopts the dependent suspension of leaf spring structure, having only both at home and abroad, some high-grade motor omnibuss use independent suspension, it as number 200720069132.5 patent by the Chinese patent Granted publication of applicant invention, name is called: the full air independent front suspension of low floor city bus, and the air bag load bearing seat of its both sides is installed on the upper and lower A type swing arm beam by last left and right A type swing arm assembly and following left and right A type swing arm assembly; Upper and lower A type swing arm beam is installed on the frame assembly; The lower end of the air bag assembly of both sides is installed in respectively on the air bag load bearing seat of both sides, and the upper end is installed in air bag by the air bag adapter plate respectively and installs on the longeron.Left and right like this suspension is independently beated, and left and right wheel is independent of each other when beating, and reduces the inclination and the vibration of vehicle body to greatest extent.This patented technology had both kept road-holding property, had improved ride comfort, had satisfied the requirement that city bus is low to preceding floor, passenger passageway is wide simultaneously.The use of independent suspension has improved the riding comfort and the road-holding property of vehicle on can be largely.
Domesticly also on the chassis of light medium bus, do not dispose independent suspension, external then have employing to turn round the independent suspension of mandarin orange spring structure form.
