Description
Technical field
The utility model relates to a kind of three-wheel vehicle front damping device, belongs to the preceding cushion technique field of three-wheel vehicle.
Background technology
Bumper is mainly used in buffering and causes the impact shock to the driver because of ground in the face of car impact, to improve comfort of drivers and passengers.The straight barrel type bumper is adopted in the preceding damping of three-wheel vehicle mostly; Mainly be made up of damping cylinder, damping spring, damper, shock structure etc., after motor bike received external impacts, shock structure moved downward; Damping spring bears pressure; The part fluid of lower oil cavitie is washed open in the ring gear valve block inflow transition oil pocket in the damping cylinder simultaneously, and the fluid of another part then flows into upper oil cavitie and transition oil pocket in the shock structure respectively through the oilhole at underpart of the piston rod and middle part, makes damper play the effect of compression damping.When front shock absorber restores; Under the elastic force effect of damping spring; The shock structure upward movement; The interior fluid of its transition oil pocket of damper this moment flows into the lower oil cavitie in the damping cylinder through the oilhole in the middle part of the piston rod, and the fluid of the interior lower oil cavitie of shock structure produces and restores damping through the lower oil cavitie of piston rod interstitial hole inflow damping cylinder.Use the three-wheel vehicle front damping device of straight barrel type bumper to have following defective: 1, because in the shock structure insertion damping cylinder; Its upper and lower motion is a cliding friction, adds vertical, the horizontal thrust of car load in going, and is prone to cause the oil sealing leakage of oil; Influence damping effect, reduce bumper service life.2, because along with the deadweight of three-wheel vehicle and the increase of load carrying ability, the anticollision property of straight barrel type damping and load all can not satisfy the demand of three-wheel vehicle, are prone to cause safety misadventure.For this reason; The preceding damping of some three-wheel vehicles adopts major and minor damping at present; The upper/lower terminal of its main bumper is installed on the front fork tube respectively; Its upper end of secondary bumper is connected with front fork tube, the lower end then be fixed on main bumper on crossbeam be connected, make the central axis of main bumper and the central axis of secondary bumper be certain included angle, so pass through to control main spring stiffness and the stiffness of the secondary damping spring on the secondary bumper on the main bumper; And through the angle between main bumper and the secondary bumper; Vehicle frequency and amplitude to front wheel bouncing on various load, various road surface is controlled effectively, avoids resonance, come to improve the traveling comfort of three-wheel vehicle.But owing to captive joint with main bumper through crossbeam in the bottom of secondary bumper; So when major and minor two bumpers are simultaneously stressed; Both part moment can occur and cancel out each other; Not only influence damping effect, also increased the manufacturing and the service precision of main damping spring and secondary damping spring simultaneously, cause processing technology complicacy and inconvenient installation.
Summary of the invention
The purpose of the utility model provides a kind of rational in infrastructure, is convenient to processing and fabricating, the three-wheel vehicle front damping device of good damping effect.
The utility model is that the technical scheme that achieves the above object is: a kind of three-wheel vehicle front damping device; It is characterized in that: comprise front fork assembly; Two groups of master's bumpers and secondary bumper; Described front fork assembly comprises two front fork tubes, be fixed on two front fork tube upper backs and be the bumper upper bracket of shaped as frame, be hinged on two following articulated slabs and the upper connective plate and the lower linking plate of bottom behind two front fork tubes respectively; Upper connective plate is installed in the top of two front fork tubes, and lower linking plate is installed on two front fork tubes and is positioned at the top of bumper upper bracket, is used for being fixed on the lower linking plate and with upper connective plate with steering shaft that seat tube matches being connected; Two front fork tubes are the arcuation for leaning forward between bumper upper bracket and following articulated slab; Twice articulated slab is respectively equipped with secondary damping hinged seat and main damping hinged seat along fore-and-aft direction, is hinged with main bumper and secondary bumper respectively on the secondary damping hinged seat of the both sides of bumper upper bracket and twice articulated slabs and the main damping hinged seat, and the central axis of main bumper is parallel with the central axis of secondary bumper; Curved following articulated slab backward and tilting downwards, the rear portion of following articulated slab is provided with the front wheel spindle mounting hole.
The utility model adopts front fork assembly; Its two front fork tubes upper back is fixed with the bumper upper bracket of shaped as frame, on the one hand main bumper and secondary bumper can be installed conveniently, improves front fork tube single-piece mechanical strength on the other hand; The back bottom of two front fork tubes is hinged with down articulated slab respectively; Therefore can two groups of master's bumpers and secondary bumper two ends be hinged on respectively on bumper upper bracket and the following articulated slab, because two front fork tubes are the arcuation that leans forward between bumper upper bracket and following articulated slab, and curved following articulated slab backward and tilting downwards; Make the support unit in the whole shock absorption device can bear the impact moment of the next all directions of front-wheel transmission rapidly; The front damping device reasonable stress, especially with the bottom bonded assembly of major and minor bumper under articulated slab be with front fork tube after bottom-hinged because articulated slab is connected with front wheel spindle down; So can be fulcrum with the front wheel spindle; Absorb and the impact endurance test shock of facing vehicle damply through two groups of master's bumpers and secondary bumper rapidly, can effectively improve the stressing conditions of front damping device, the service life of improving front damping device.The utility model will make secondary bumper and main bumper be hinged on down on the articulated slab along fore-and-aft direction, and articulated slab is tilting down, therefore when driving is unloaded; Though make main bumper and secondary bumper receive force compresses simultaneously, it is stressed to be merely main bumper, and take advantage of or when going on rugged road increase carrying; After main bumper is compressed to certain stroke; Secondary bumper carries out work, because the central axis of main bumper is parallel with the central axis of secondary bumper, so make main bumper and the secondary bumper impulsive force of stressed, common buffering, the suffered all directions that decay simultaneously; That satisfies driving person feels comfortable; And can reduce stiffness requirement to damping spring, the front damping device of the utility model is simple in structure, owing to need not main bumper and secondary bumper are improved; Good manufacturability is convenient to processing and fabricating, installation and maintenance.
