Technical field
The utility model belongs to commercial vehicle/comm..vehicle suspension system vibration isolation technique field, specifically, relates to full-floating commercial-vehicle cab front-suspension system, for commercial-vehicle cab vibration reduction and cushioning, improves commercial-vehicle cab travelling comfort and riding comfort.
Background technology
Cab mounting connecting vehicle frame and operator's compartment, allow the relative motion between them simultaneously, to ensure the normal traveling of vehicle.Cab mounting forms primarily of following components, 1. vibration insulating system, comprises elastic element, shock absorber; 2. anti-roll system, mainly comprises Panhard rod; 3. lockable mechanism, ensures the connection of operator's compartment and vehicle frame when effect is and normally works; 4. switching mechanism, for the upset of operator's compartment, is convenient to the maintenance of the parts such as driving engine; 5. stop gear, the normal upset of restriction abnormal vibrations and guarantee operator's compartment; 6. other transoms.Suspension system Main Function has, support operator's compartment, bear the quality of operator's compartment assembly and occupant, make the excessive Static Correction of its unlikely generation and affect and normally work and guide operator's compartment relative to the perpendicular movement on chassis, also require that operator's compartment and vehicle frame have firm connection, must not depart from simultaneously; Function of shock insulation, has good vibration isolation effect, and the Uneven road excitation etc. that can decay is delivered to vibration and the impact of operator's compartment; Realize driver's cab turnover, realized the turn over function of operator's compartment by linkage, so that the maintenance of operator's compartment.
Conventional commercial car to travelling comfort require lower, only have between vehicle frame and vehicle bridge and have employed shock attenuation unit, and vehicle frame and operator's compartment are directly rigidly connected, therefore travelling comfort and riding comfort poor, chaufeur is easily tired.Have developed semi-floating suspension system subsequently, front-suspension adopts the cushioning effect of rubber coating, rear-suspending adopts coil spring or shock absorber to carry out damped vibration, semi-floating suspension system serves certain vibration isolation effect, but rigidity and the damping of the rubber coating of front-suspension are limited, travelling comfort is still not ideal, and chaufeur still easily feels tired, and internal car noise is very large.
For commercial vehicle/comm..vehicle, in whole vehicle vibration damping system, Cab Mounting System is extremely important component part, and to guaranteeing vehicle safety, comfortable and reliability is significant.Therefore, comprehensively must test during the research and development of full-float cab suspension system, guarantee that it has superior cushioning performance and traveling comfort.
At present, some domestic Cab Mounting Systems are comparatively numerous and diverse, and be with trouble to assembling, Expenses Cost is high, so far extend time-to-market and the round of visits of full-floating suspension system.
Therefore, design a kind of structure simple, reliable operation, lightweight full-float cab suspension system is very important.
Summary of the invention
Not good in order to solve semi-floating suspension system effectiveness in vibration suppression, assembling inconvenience, the deficiency that suspension system weight is large, the utility model proposes a kind of full-floating commercial-vehicle cab front-suspension system, it is simple and reliable for structure, can realize good vibration isolation, improve travelling comfort.
The technical scheme that the utility model adopts is: full-floating commercial-vehicle cab front-suspension system, is characterized in that:
Comprise front-suspension upper bracket, swing arm, limit base, front-suspension lower bracket, front-suspension shock absorber, Panhard rod, front-suspension lower bracket, swing arm are connected to the two ends of Panhard rod successively from outside to inside, and front-suspension upper bracket is connected to above swing arm; Described front-suspension shock absorber is spring complex liquid pressure damper, is cylinder type damper and helical spring integrated; Spring complex liquid pressure damper is arranged between front-suspension upper bracket and front-suspension lower bracket; Limit base is arranged on front-suspension lower bracket, plays position-limiting action to the swinging end of swing arm; During installation, front-suspension upper bracket is connected with operator's compartment, and front-suspension lower bracket is connected with vehicle frame.
Further restriction to technique scheme: in described spring complex liquid pressure damper, coil spring coaxial package is on the piston rod of cylinder type damper, spacing by the cylinder barrel of cylinder type damper, thus coil spring and cylinder type damper are become one, structure is simple, save space, there is the effect little, easy to assembly that takes up room.
Further restriction to technique scheme: front-suspension upper bracket adopts blanked part by being welded, and front-suspension lower bracket adopts Casting Parts, under the prerequisite reaching load-carrying capacity, reduces weight as far as possible; Described Panhard rod adopts wall thickness to be the hollow shaft of 4-6mm, can bear enough torques and moment of flexure, improves anti-roll capability.
Limiting again technique scheme: the fixed end of described swing arm is hinged on Panhard rod.
The beneficial effects of the utility model: the utility model is applied to commercial vehicle/comm..vehicle, adopt spring complex liquid pressure damper, the energy of concussion when cylinder type damper rebounds after being used for suppressing spring shock-absorbing and absorption road shocks, spring plays a part to relax impact, " macro-energy one-shot " is become " small capacity hump ", good effectiveness in vibration suppression can be reached, improve the travelling comfort of commercial vehicle/comm..vehicle, reduce the sense of fatigue of chaufeur.This utility model practicality is good, and structure is simple, takes up room little, easy to assembly.Product development and the test period short, cost is low.
Accompanying drawing explanation
Fig. 1 is composition schematic diagram of the present utility model.
Fig. 2 is the structure of spring complex liquid pressure damper in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
