Thereby, the utility model solves the problem of reducing the suspended weight, and improves the control stability of the automobile.
Description
(1) technical field
The utility model relates to a kind of air suspension of automobile, particularly a kind of quasi-sovereign suspension.
(2) background technology
The suspension of automobile is elastic element and the system that damping vibration attenuation is arranged, and not only influences the ride comfort of automobile, also influences the life-span of road holding and parts.Traditional dependent suspension, i.e. the suspension of main gearbox assembly in the axle housing of rear axle, when automotive wheel is upper and lower when beating, main reduction gear must and axletree is upper and lower together beats.And driving engine is fixed on vehicle frame or the vehicle body together with change-speed box, and it is not beated, and in order to adapt to this operating mode, generally all need install the transmission shaft that can swing additional between change-speed box and main reduction gear, and this just makes suspension too heavy.Since the length of this root transmission shaft under flexible state usually more than 350 millimeters, rear overhang is long with regard to distance between the forward and backward axle of rear-engine bus about 8 meters is shortened greatly, the result will cause passenger vehicle under light condition, during particularly unloaded up-hill journey, preceding axle load kicks the beam, the road-holding property of automobile is degenerated, can make the automobile loss of control when serious.
(3) utility model content
The purpose of this utility model provides a kind of later-model semi-independent suspension, solves the problem that main gearbox assembly is not beated with axletree and alleviated outstanding load carrying ability; And solve existing suspension and make vehicle wheel base too short and rear overhang is long, when unloaded up-hill journey before the axle load problem that kicks the beam, make the road-holding property of automobile to reduce.
The purpose of this utility model is achieved in that this semi-independent suspension, under connect train, on connect vehicle frame, axle tube and back-plate support are housed on the transmission shaft of train, suspension system comprises air bellow, bumper, U-shaped Panhard rod, lateral rod and longitudinal rod, it is characterized in that: the left and right sides equalizing bar of equalization frame is passed at the two ends, the left and right sides of transmission shaft, is supported on the equalizing bar of the left and right sides by axle tube; The bottom of four air bellows is located the rear and front end that is connected left and right sides equalizing bar respectively, captives joint with two longerons of vehicle frame in the top of four air bellows; Connect forward and backward crossbeam between the left and right equalizing bar of equalization frame, form the intersecting parallels framework; Hang between vehicle frame and the equalization frame be connected bumper, U-shaped Panhard rod, lateral rod and about two longitudinal rods; Connect main gearbox assembly by the main gearbox assembly support on the vehicle frame, main gearbox assembly is in transmission connection through driving device and transmission shaft.
Above-mentioned driving device is universal-joint-pin type universal transmission shaft, curved grooved type angular speed universal driving device or ball cage type angular speed universal driving device.
Above-mentioned lateral rod is arranged on the two bar lateral rods before and after the main gearbox assembly.
The utility model is compared the beneficial effect that has with existing conventional art:
The utility model is at the suspension mode of operation, main gearbox assembly is not beated, by U-shaped Panhard rod, preceding lateral rod, back lateral rod, about two longitudinal rods form six rod-types guiding force transmission mechanism, improved the ride comfort of automobile, strengthened the road-holding property of automobile, and the damping vibration attenuation performance is good, has improved wheel and ground-surface attachment state, improve the ride comfort and the directional balance of automobile, prolonged the life-span of parts.
The utility model spins off main gearbox assembly from back axle, and be fixed on vehicle frame or the vehicle body, thereby can cancel the transmission shaft of 350 millimeter, change-speed box and main reduction gear are directly connected together, main reduction gear transmits power to the wheel limit and adopts traditional universal-joint-pin type universal driving device, because it does not have axle housing, main gearbox assembly is installed in again on the vehicle frame or on the vehicle body, so its non-outstanding load carrying ability can obviously reduce, and has improved the ride comfort of automobile; The change of this structure just can guarantee vehicle wheel base to be strengthened 350 millimeter, thereby corrected the problem that preceding axle load kicks the beam under passenger vehicle length unmodified situation.Because it has cancelled the universal driving device between change-speed box and the main reduction gear, for the passenger vehicle of rear-mounted engine, the limited amount that part increases.
With 9 tonnes of vehicle bridge and suspension is example, and whole bridge and suspension system weight are about 700 kilograms, and semi-independent suspension system weight can be within 450 kilograms.The reduction of non-outstanding charge material amount can reduce the impact of road pavement, improves ground-surface service life.The ride comfort that reduces also can improve automobile of non-in addition outstanding charge material amount.
