Abstract
The prestress ship shape beam of battery-operated motor cycle adopts sheet steel prestress method to be welded, and has the bending resistance torsional strength, and materials are economized, and are in light weight, takes advantages such as steadily comfortable.
Description
The present invention relates to the beam frame structure of battery-operated motor cycle.
Existing battery-driven two-wheeled electrocar, most tubular type girder constructions that adopt bicycle rack, useful truss girder structure of minority such as British patent 1559777, because cycle frame is according to low velocity underload design-calculated, load onto storage battery, behind the electrical motor again with 20 kilometers/time above speed travel, counter-bending and the anti-torsional strength of vehicle frame steel pipe is all not enough, the influence of being jolted, front fork tube and connection place, rear portion easily produce torsional deflection, cause front and back wheel misaligned, the truss girder of British patent is to be gasoline motor bike design-calculated, and storage battery can not be laid in the centre, front fork partly is the quadrangle unstable structure, and stressing conditions is not good.
Task of the present invention is: design a kind of roof beam structure of in light weight, battery-driven car that the bending resistance torsional strength is high, drive steadily to satisfy, the requirement of ride comfort.
The solution of invention is: the prestress ship shape beam that adopts the sheet steel welding, its side plate is band muscle arch sheet, and the bottom surface tie rod welds in the centre earlier, and forward and backward two base plates add the welding of reversed bending stress in advance, front fork tube is welded in the parabola shape side plate, has finished this task smoothly.
The ship shape beam is a side plate with two band muscle arch sheet steels, the middle upper portion opening, battery frame of inner weldering, the side plate front end curves parabola shape and front fork tube is welded into one, front end has also welded a upper cover plate, the battery frame bottom surface is bored 4 holes and is used for fixing gear case, anterior, two base plates in rear portion also are band muscle arch sheets, after welding in the middle of the tie rod of bottom surface, front floor, heel slab add reversed bending stress and side plate solder together in advance, weldering cover plate in roof beam structure upper back is used for laying saddle, and saddle tiltedly has bearing pin to be used for installing rear shock absorber on the side plate of below.
Advantage of the present invention is: storage battery, electrical motor and gear case are contained in the middle and lower part of roof beam structure, reduced vehicle's center of gravity, the middle part amplitude of ship shape roof beam structure is minimum, the vertical dynamic load minimum, energy and reversed bending stress balance each other behind the prestress ship shape load bearing beam, bending stiffness is good, can reduce steel board consumption and deadweight, the reversal interlocking relay that middle prestress tie rod produces and the equilibrium of pressure of static weight, improved structural strength,, can reduce the permanent deformation of vehicle frame for the buffer action of the live load in travelling owing to the elastic bending of ship shape beam, load when the parabola structure road pavement injustice of front fork or turning all can be born, and can prevent the vehicle frame distortion.
The example of accompanying drawing is further described invention below utilizing
The prestress ship shape beam front elevation and the A-A section-drawing of Fig. 1 battery-operated motor cycle
The prestress ship shape beam birds-eye view of Fig. 2 battery-operated motor cycle
Vehicle frame ship shape beam is by front fork sleeve pipe 1 left and right side plate 2, battery frame 9, preceding upper cover plate 8, back upper cover plate 10, front floor 3, heel slab 5, bottom surface tie rod 4, compositions such as lock shaft 6,7, battery frame 9 bottom surfaces have 4 holes to be used for fixing gear case, the front portion of left and right side plate 2 curves parabola shape and 1 welding of front fork sleeve pipe, preceding upper cover plate 8, the front end of front floor 3 also welds with the front fork sleeve pipe, has two lugs to be used for installing saddle on the back upper cover plate 10, the Shock absorber that lock shaft 6,7 on the left side plate is used for adorning on the trailing wheel, front fork sleeve pipe 1 is in order to dress front fork and front shock-proof device device.
Claims (1)
1, battery-operated motor cycle, the chassis frame of particularly battery-driven two-wheel battery-operated motor cycle, it is characterized in that: vehicle frame is the prestress ship shape beam of sheet steel welding, it is side plate (2) by two band muscle arch sheet steels, the front portion curves parabola shape and front fork sleeve pipe (1) welding, preceding upper cover plate (8), battery frame (9), lower cover (3), back lower cover (5) are with reverse tensioning and side plate (2) solder together before the band muscle arch, and back upper cover plate (10) welds with side plate.There is bearing pin (6) (7) to be used to install the trailing wheel Shock absorber on the side plate (2).
