Description
Technical field
The present invention relates to a kind of automobile auxiliary device, be specifically related to the front hung holder of truck cab.
Background technology
Along with the development of China Transportation Industry, the traveling comfort of vehicle is required increasingly high, during high vehicle speeds, be delivered to vibration and the driving engine of operator's compartment, the vibration that transmission system is delivered to (mainly being radio-frequency component) on the operator's compartment through suspension by the road surface.The operator's compartment of domestic main goods carrying vehicle product is most at present adopts with the suspension system of elastomeric material as suspension members; This structure is gone under the condition of smooth-riding surface with the low speed of a motor vehicle for vehicle, and the vibration that is delivered on the operator's compartment has certain obstruct and mitigation.But when vehicle goes under speed of a motor vehicle condition with higher; Or when a bit weaker travels down of pavement conditions, rubber mounting is damped vibration well just, and structural vibration that produces in the operator's compartment and the constructional noise that is caused by high-frequency vibration are bigger; Thereby reduced the traveling comfort of operator's compartment; Also make cab structure under oscillating action, be easy to generate fatigue damage, subjectively make chaufeur and occupant feel uncomfortable, going for a long time is easy to generate fatigue.For this reason, use some entirely floating suspending apparatus at present on the vehicle, it can effectively reduce the vibration of operator's compartment, improves the traveling comfort of chaufeur, alleviates the degree of fatigue of long-duration driving, and the safety that can improve vehicle.The suspending apparatus of autotruck with reference to roadlice draft hitch and design, but the problem that autotruck exists operator's compartment when maintenance, need overturn, thus autotruck before suspend and also have its particularity.For example 200620095941.9 utility model discloses " a kind of operator's compartment full-floating front suspension device ", is made up of with the Panhard rod that is connected left and right mounting assembly left and right mounting assembly, and the structure of left and right mounting assembly is symmetry fully; Each mounting assembly comprises and cab anchorage bonded assembly upper bracket, spring, vibration damper complement, trip shaft, the undersetting of captiveing joint with vehicle frame.Its scheme is utilized a spacing rubber coating to concentrate and has been accomplished the upper and lower spacing of operator's compartment, and utilize the relatively stable of vehicle, but there is the deficiency of the following aspects in this structure: 1. spring separates installation with shock absorber, and it is big to take up room.2. spring and last undersetting lean on plane contact, and it is inharmonious in motion process, to understand generation, can reduce spring life.3. at switching process medi-spring infinite place, operator's compartment can produce instability.4. complex structure, relative weight is big.
Summary of the invention
Complete floating cab comfort is poor in order to solve in the prior art, the defective of poor stability, and the present invention provides a kind of simple in structure, tilt-stable, perpendicular movement and the separate floating full rear suspension device of operator's compartment of trim motion.Concrete scheme is following: a kind of full-floating front suspension device of automobile; Comprise lateral stability frame, left suspension device and right suspension installation; It is characterized in that, said left suspension device, the right suspension installation structure both sides that are installed in the lateral stability frame in full accord and symmetrical, said lateral stability frame comprises torsion tube and is installed in the flip-arm at torsion tube two ends; Said left suspension device, right suspension installation comprise upper bracket, undersetting, bumper and guide arm respectively; One end of upper bracket and undersetting is connected with flip-arm respectively, and an end of bumper is connected the other end and is connected with flip-arm with upper bracket, and an end of guide arm is connected the other end and is connected with undersetting with upper bracket.
Another optimal way of the present invention: the centre of said flip-arm and torsion tube adopt welding manner to be fixed together, and the two ends of flip-arm have pin-and-hole A, pin-and-hole B respectively.
