Abstract
The prestress ship shape beam of battery-operated motor cycle, adopts sheet steel prestress method to be welded, and has bending resistance torsional strength, and materials are economized, lightweight, takes the steadily advantage such as 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, the useful girder frame structure of minority is as British patent 1559777, because bicycle rack designs according to low velocity underload, load onto storage battery, after electrical motor again with 20 kilometers/time above speed travel, counter-bending and the torsional strength of vehicle frame steel pipe is all inadequate, the impact 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 gasoline motorcycle design, storage battery can not be laid in centre, front fork part is quadrangle unstable structure, stressing conditions is not good.
The object of the invention is: design a kind of roof beam structure of lightweight, battery-driven car that bending resistance torsional strength is high, drive steadily, take advantage of comfortable requirement to meet.
The solution of invention is: the prestress ship shape beam that adopts sheet steel welding, its side plate is band muscle arch sheet, and bottom surface tie rod first welds in centre, and forward and backward two base plates add the welding of reversing tube transverse stress in advance, front fork tube is welded in parabola shape side plate, has completed smoothly this task.
Ship shape beam is take two band muscle arch sheet steels as side plate, middle upper portion opening, battery frame of internal welding, its structure are the square chests of opening above, two storage batterys can be put down in the inside, and it is welded into by many bar steel, before, be three horizontal stripes below, two sides are four vertical bars, bottom surface is four horizontal stripes and three vertical bars, and it is again the reinforced rib of side plate that bar steel can be subject to the weight of storage battery, and battery frame bottom surface is bored four holes and is used for fixing gear case.Side plate front end curves parabola shape and front fork tube is welded into one, and in order to fill up interface space and to strengthen frame strength, a front upper cover plate has also been welded on front fork tube top.Anterior, two, rear portion base plate is also band muscle arch sheet steel, and after welding in the middle of three vertical bars of storage battery underframe, two ends weld after cooling and cause shrink stress with the rear end of front floor and the front end of heel slab respectively.When anterior, heel slab and plate-side plate welding, add in advance K/UP external force, be soldered and remove external force, cooling rear ship shape beam recovers original shape and has produced and be bent downwardly stress, on roof beam structure, a cover plate of rear portion weldering, 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.Middle part has a movable shape of a saddle battery cover to be used for hiding storage battery, plays dustproof, rainproof effect, but does not bear external force.
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, have reduced vehicle's center of gravity.The middle part amplitude of ship shape beam is minimum, vertical dynamic load minimum, after prestress ship shape joist support is heavy, and being bent downwardly prestress balances each other, bending stiffness is good, can reduce steel board consumption and deadweight, the convergent force that middle tie rod produces and the equalization of strain of static weight, improve structural strength, for the live load in travelling, due to the buffer action of the elastic bending of ship shape beam, can reduce the permanent deformation of vehicle frame, the load when throwing line structure road pavement injustice of front fork or turning all can be born, and can prevent vehicle frame distortion.
Utilize the example of accompanying drawing to be below further described invention
The prestress ship shape beam front elevation of Fig. 1 battery-operated motor cycle
The prestress ship shape beam birds-eye view of Fig. 2 battery-operated motor cycle
Fig. 3 battery frame front elevation
Vehicle frame ship shape beam is by front fork sleeve pipe 1, left and right side plate 2, battery frame 9, front upper cover plate 8, rear upper cover plate 10, front floor 3, heel slab 5, the compositions such as bearing pin 6,7.Battery frame 9 opening above, above, there are three horizontal stripes below, two sides are four vertical bars, bottom surface is four horizontal stripes and three vertical bars, battery frame 9 bottom surfaces have four holes to be used for fixing gear case, left, the front portion of right side board 2 curves parabola shape and front fork sleeve pipe 1 welds, front floor 3 is band muscle arch sheet steels, its front end and front fork sleeve pipe 1 weld, three bottom surface vertical bar welding of its rear end and battery frame 9, front upper cover plate 8 front ends and front fork sleeve pipe 1 weld, both sides are with left, right side board 2 welds, heel slab 5 is also three of the bottom surfaces vertical bar welding with its front end of muscle arch sheet and battery frame 9, remainder and plate-side plate welding.Rear upper cover plate 10 and two side plates 2 weld, and have two lugs to be used for installing saddle above it.The Shock absorber that bearing pin 6,7 on left and right side plate is used for installing on trailing wheel, front fork sleeve pipe 1 is in order to install front fork and Shock absorber.
