Description
Technical field
The invention belongs to commercial car suspension system vibration isolation technique field, specifically, is related to full floating commercial-vehicle cab front-suspension system, for commercial-vehicle cab vibration reduction and cushioning, commercial-vehicle cab riding comfort and ride performance are improved.
Background technology
Cab mounting connecting vehicle frame and driver's cabin, while the relative motion between them is allowed, to ensure the normally travel of vehicle.Cab mounting is mainly made up of following components, 1. vibration insulating system, including flexible member, shock absorber；2. anti-roll system, mainly including QS；3. lockable mechanism, ensures the connection of driver's cabin and vehicle frame when effect is normal work；4. switching mechanism, for the upset of driver's cabin, is easy to the maintenance of the parts such as engine；5. position-limit mechanism, limits abnormal vibrations and ensures the normal upset of driver's cabin；6. other connecting elements.Suspension system Main Function has, driver's cabin is supported, and bears the quality for driving chamber assembly and occupant so as to excessive Static Correction will not be produced and affected normal work and driver's cabin is guided relative to the vertical movement on chassis, also require that driver's cabin and vehicle frame have firm connection simultaneously, must not depart from；Function of shock insulation, acts on good vibration isolation, and Uneven road of can decaying excitation etc. is delivered to the vibration and impact of driver's cabin；Driver's cab turnover is realized, the turn over function of driver's cabin is realized by linkage, in order to the maintenance of driver's cabin.
Conventional commercial car requires relatively low to riding comfort, only employs vibration absorber between vehicle frame and vehicle bridge, and vehicle frame and driver's cabin are directly rigidly connected, therefore riding comfort and ride performance are poor, and driver is easily tired.Semi-floating suspension system is have developed subsequently, cushioning effect of the front-suspension using rubber sleeve, rear-suspending is decayed using helical spring or shock absorber vibration, semi-floating suspension system serves certain vibration isolation effect, but the rigidity of the rubber sleeve of front-suspension and damping are limited, riding comfort is still not ideal, and driver still easily feels fatigue, and internal car noise is very big.
For commercial car, in whole vehicle vibration damping system, Cab Mounting System is extremely important part, significant to guaranteeing vehicle safety, comfortable and reliability.Therefore, comprehensively must be tested when full-float cab suspension system is researched and developed, it is ensured which possesses superior damping property and comfortableness.
At present, some domestic Cab Mounting Systems are more numerous and diverse, and to assembling with trouble, Expenses Cost is high, so far extends construction cycle and the round of visits of full floating suspension system.
Therefore, a kind of simple structure is designed, reliable operation, lightweight full-float cab suspension system are very important.
The content of the invention
It is not good in order to solve semi-floating suspension system effectiveness in vibration suppression, assembling inconvenience, the big deficiency of suspension system weight, the present invention proposes a kind of full floating commercial-vehicle cab front-suspension system, which is simple and reliable for structure, can realize preferable vibration isolation, improve riding comfort.
The technical solution adopted in the present invention is：Full floating commercial-vehicle cab front-suspension system, it is characterised in that：
Including front-suspension upper bracket, swing arm, limit base, front overhang lower support, front-suspension shock absorber, QS, front overhang lower support, swing arm are connected to the two ends of QS successively from outside to inside, and front-suspension upper bracket is connected to above swing arm；The front-suspension shock absorber is the compound hydraulic buffer of spring, is that cylinder type damper is integrated with helical spring；The compound hydraulic buffer of spring is arranged between front-suspension upper bracket and front overhang lower support；Limit base is arranged on front overhang lower support, plays position-limiting action to the swinging end of swing arm；During installation, front-suspension upper bracket is connected with driver's cabin, and front overhang lower support is connected with vehicle frame.
Further restriction to above-mentioned technical proposal：In the compound hydraulic buffer of the spring, helical spring coaxial package is on the piston rod of cylinder type damper, spacing by the cylinder barrel of cylinder type damper, so as to helical spring is become one with cylinder type damper, simple structure, save space, with little, the easy to assembly effect that takes up room.
Further restriction to above-mentioned technical proposal：Using stamping parts by being welded, front overhang lower support adopts cast member to front-suspension upper bracket, on the premise of bearing capacity is reached, reduces weight as far as possible；The QS adopts wall thickness for the hollow shaft of 4-6mm, can bear enough torques and moment of flexure, improves anti-roll capability.
Limiting again to above-mentioned technical proposal：The fixing end of the swing arm is hinged on QS.
Beneficial effects of the present invention：The present invention is applied to commercial car, using the compound hydraulic buffer of spring, the energy of concussion and absorption road shocks when cylinder type damper rebounds after being used for suppressing spring shock-absorbing, spring plays a part of to relax impact, " big energy one-shot " is changed into into " small capacity hump ", preferable effectiveness in vibration suppression can be reached, the riding comfort of commercial car is improve, reduces the sense of fatigue of driver.The invention practicality is good, and simple structure takes up room little, easy to assembly.Product development and test period are short, low cost.
Description of the drawings
Fig. 1 is the composition schematic diagram of the present invention.
Fig. 2 is the structure of spring complex liquid pressure damper in the present invention.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
