Description
Technical field
The utility model relates to a kind of frame of motorcycle, particularly a kind of integral type right three-wheeled motorcycle carframe.
Background technology
Existing Trimotorcycle frame adopts keel type structure, and this construction torsion rigidity is poor, and vehicle frame in use easily produces distortion.Due under vehicle dead weight and loading condition, the stressed size of diverse location of vehicle frame is also different, meanwhile, due to rectangular tube, need to roll over multiple tracks curved, and in Forging Process, bending part can produce stress because of distortion, because inside and outside both sides deflection is different, i.e. the outer side stretching of inner side extruding, thus suffered stress is different, cause shaping Rear frame distribution of stress uneven, also make reduce the service life of car load.Usually between keel and the front cross rail of portal frame, adopt welding connection structure, because there is stress weld and metallographic structure is poor, its corrosion stability and intensity are all poor.The moment of torsion produced when motor-tricycle turns round, is easy to make the attaching parts between keel and front cross rail produce torsional fracture and weld is easy to split, so need constantly maintenance.Simultaneously because attaching parts and keel and front cross rail are all that single vertical is connected, because the stress produced when motor-tricycle turns round very easily causes damage to single attaching parts, whole keel and portal frame well can not be linked together, be easy to torsional fracture, it is not firm to connect, and causes risk.
In actual practice, the stretcher of motor-tricycle is little, and the sense of security of chaufeur is reduced.In addition, due to the limitation of stretcher area, the pin of chaufeur limitedly can only be placed on the position of stretcher, when driving over a long distance, due to the limited location of pin, chaufeur deliberately can only control the activity space of legs and feet, thus cause chaufeur legs and feet tired, do not meet the driving demand of hommization.
Obviously, prior art Trimotorcycle frame also exists and is easily out of shape torsional fracture, and integrated connection is not firm, and stiffness and strength is poor, affects loaded weight, pedal makes the uneasy congruent problem of chaufeur.
Summary of the invention
For solving the easy distortion torsional fracture that prior art Trimotorcycle frame exists, integrated connection is not firm, and stiffness and strength is poor, affect loaded weight, pedal makes the congruent problem of chaufeur uneasiness.The utility model proposes a kind of right three-wheeled motorcycle carframe of integral type.
The utility model integral type right three-wheeled motorcycle carframe, comprises left keel, right keel, is arranged at left outside side bar on the left of left keel, is arranged at the right outside side bar on the right side of right keel, double-U-shaped bumper/spoiler and portal frame; The front hanger that described portal frame comprises front cross rail, be arranged at front cross rail two ends and the perpendicular after-frame side bar of front cross rail respectively, be arranged on after cross member between two described after-frame side bars, be arranged at after cross member two ends respectively; The front end of described left keel and right keel takes the shape of the letter U in the welding of motor-tricycle front portion, and described U-shaped bumper/spoiler is welded in the left side of left keel front end and the right side of right keel front end respectively; Described left outside side bar front end is welded with U-shaped bumper/spoiler, and rear end is welded mutually with the front hanger of after-frame side bar and after cross member one end, and described right outside side bar front end is welded with U-shaped bumper/spoiler, and rear end is welded mutually with the front hanger of after-frame side bar and the after cross member other end; It is characterized in that: between the middle part of described left outside side bar, left keel, right keel and right outside side bar and the front cross rail of portal frame, be connected to vertical support tube; Between the adjacent described vertical support tube in both sides, level connection joint has some reinforced ribs; Described left keel, right keel, left outside side bar, right outside side bar, double-U-shaped bumper/spoiler and portal frame are integrally formed structure.
Further, described vertical support tube is connected with left outside side bar, left keel, right keel, right outside side bar and front cross rail respectively by bolt; Described reinforced rib is connected with vertical support tube respectively by bolt.
Further, described vertical support tube and reinforced rib are respectively hollow structure, and its two ends are fixedly installed the end connecting panel that can be interfixed by bolt respectively.
Further, 2 reinforced ribs are connected between the adjacent described vertical support tube in both sides.
Further, the full envelope pedal being separately positioned on the left of left keel and on the right side of right keel is also comprised; Full envelope pedal on the left of described left keel welds mutually with U-shaped bumper/spoiler, left keel and left outside side bar and extends to the rear portion of the front cross rail of portal frame; Full envelope pedal on the right side of described right keel welds mutually with U-shaped bumper/spoiler, right keel and right outside side bar and extends to the rear portion of the front cross rail of portal frame.
Further, hanger after the both sides at two after-frame side bar rear portions are also provided with respectively, described front hanger and rear hanger are made up of heavier-duty steel plate.
Further, between left keel and right keel, also tie-beam is provided with.
Integral type right three-wheeled motorcycle carframe stiffness and strength of the present utility model is large, and integrated connection is firm, and not yielding torsional fracture, loading mass are large, safe and reliable.
