Description
Technical field
The present invention relates to rear axle of scooter, especially a kind of mobility scooter for old people rear axle.
Background technology
As China comes into the aging stage, elderly population can be more and more, while with the development of economy, rural area
Also convergence is perfect for road construction with city, in addition the trip mode of new energy, more environmentally friendly；After existing mobility scooter for old people
There are two types of bridges：
The first is beam rear axle, independent one of speed reducer assembly, then independent one of rear axle housing body is reloaded into other
Component, this rear axle structure are used on the electric tricycle rearmost axle of freight carrying type, and mobility scooter for old people is not used in loading, traveling
Speed is low, causes the cost installed, manufacture, produced higher using this structure design, design waste.
Second is independent one of speed reducer assembly, and the two is bolted one independent one of rear axle pipe assembly
It rises, it is this to be called split rear axle；This design concept is more advantageous than the first, but connection bolt quantity is more, for dress
Not perfect with craftsmanship, excessively high to processing technology requirement, more using material in structure design, cosmetic look is poor, valency
Lattice cost is higher.
The content of the invention
The technical problem to be solved by the present invention is to：In order to solve the existing deficiency there are two types of rear axle, one kind is provided and aims at old age
The rear axle of scooter of people's design.
The technical solution adopted by the present invention to solve the technical problems is：A kind of mobility scooter for old people rear axle, including axle, axis
Hold, reduction box, two shaft assemblies in reduction box and differential mechanism, rear bridge tube, brake fixed plate and brake hub, the case of reduction box
There is symmetrically arranged casing in vitro, rear bridge tube is provided in casing, one end and the sleeve interference of rear bridge tube coordinate, rear bridge tube
The other end welds after tube expansion is handled with brake fixed plate, and stent is welded on rear bridge tube, is offered in described sleeve pipe for solid
The first location hole and the second location hole of bridge tube after fixed, the axis of the first location hole is perpendicular to stent, the axis of the second location hole
Perpendicular to the axis of the first location hole.
In order to increase casing strength, on the position of described sleeve pipe outer wall surrounding and stagger the first location hole and the second location hole
It welds or integrally formed with reinforcing rib.
In order to mitigate dead weight, the reduction box is assembled by first shell and second shell, and two housings are aluminum hull.
As preference, it is integrally formed or is welded with symmetrically arranged casing outside the babinet of the reduction box.
The invention has the advantages that the mobility scooter for old people rear axle of the present invention, existing two kinds of rear axle forms are merged
Come, not only had the structure type of integral rear axle but also had second of split rear axle structure form；The bicycle for old people rear axle of the present invention makes
With support configurations, it is fixed to when bicycle for old people rear axle is installed on vehicle using stent and bolt on old vehicle carriage, phase
It being hung directly from when in both sides bridge tube on vehicle frame, the aluminum hull of speed reducer is actual to be not subject to load, when motor has just started rotation,
Motor can have the turning moment of circumferencial direction with retarder, in order to prevent rear bridge tube rotation, so using interior six on casing
Angle flush end holding screw is fastened, and respectively using two interior hexagonal flush end holding screws on casing, angle is 90 degree and is consolidated
It is fixed；Bridge tube uses welding form with brake fixed plate after also, and cancelling the original welded property of bolt connection increases intensity,
Old kickstand distance and brake fixed plate are close simultaneously, are easily installed, and rear bridge tube carries out tube expansion, processes, adopts convenient for bearing rib
With root bead plumber's skill, tube expansion processing is carried out, using above design, is ensureing safety and service life so that entire
The cost reduction of bicycle for old people rear axle, appearance, which lacks, to be bolted, aesthetics enhancing, integraty enhancing.

Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows composition related to the present invention.
Fig. 1 and a kind of mobility scooter for old people rear axle shown in Fig. 2, both as deceleration after 2 assembly of first shell 1 and second shell
The babinet of case uses again as the connection of rear axle main body, and first shell 1 and 2 inside of second shell are equipped with two shaft assemblies 3, bearing and difference
Fast device 4, wherein 4 bearing of differential mechanism, 6007 bearings 5, on 6007 bearing, 5 side equipped with 16004 bearings 6, by 16004 bearings 6
Side is equipped with oil sealing 7, is pre-tightened using soket head cap screw 19 and 6 spring washers 20 of Φ, forms reduction gearbox assembly；8 one end of bridge tube essence afterwards
After processing, inside interference insertion reduction gearbox assembly, i.e. in casing 21, formed and be interference fitted, the welding support 9 on rear bridge tube 8, and
It will be welded after rear 8 shaft end tube expansion of bridge tube with brake fixed plate 11；18 and 6204 bearing 10 of axle, after loading, bridge tube 8 is simultaneously
And limitation axially position is carried out using hole card spring 13, brake block and other attachmentes are mounted in brake fixed plate 11, in axle
Axle sleeve 12 and brake hub 14 on 18 are installed, pre-tightened using 16 spring washers 16 of Φ and slotted nut 17, rear bridge tube 8 revolves in order to prevent
Turn, respectively using two interior hexagonal flush end holding screws 15 on casing 21, angle is 90 degree and is fixed, the interior hexagonal after tightening
Flush end holding screw 15 withstands rear bridge tube 8, limits and is rotated on circumference.
In practice：
Using stent 9 and bolt when bicycle for old people rear axle is installed on vehicle, rear axle is fixed on old vehicle carriage, quite
It is hung directly from both sides bridge tube on vehicle frame, first shell 1 and second shell 2 are actually not subject to load, have just started in motor
During rotation, reduction box has the turning moment of circumferencial direction, and the rear bridge tube 8 in casing 21 rotates in order to prevent, so covering
It is fastened on pipe 21 using interior hexagonal flush end holding screw 15, uses two interior hexagonal flush end holding screws on casing 21 respectively
15, angle is 90 degree.
With brake fixed plate 11 using welding form, cancellation is bolted bridge tube 8 after also, and welded property increases, always
Year kickstand 9 is close apart from brake fixed plate 11, is easily installed, and rear bridge tube 8 carries out tube expansion, is processed convenient for bearing rib, using one
Root bead plumber's skill carries out tube expansion processing.
It carries out disassembling repair for rear axle failure one side during repair, rear axle need not all be removed, it is time saving and energy saving, specifically
Say, reduction box repair removes the bolt on a side stand 9 and connects the bolt of first shell 1 and second shell 2 just can be to subtracting
Fast case carries out maintenance；The bolt on failure side stand 9 is removed in the repair of one side axle 18, two interior hexagonals on casing 21 are put down
Holding screw 15,16 spring washers 16 of Φ and slotted nut 17 are held, bridge tube 8 after pulling of taking advantage of a situation can just carry out maintenance axle.
Above the specification of oil sealing 7 is Φ 20X Φ 42X5, and the specification of rear bridge tube 8 is Φ 48X3.0, and brake fixed plate 11 is
130 brake fixed plates, the specification of hole card spring 13 are Φ 47, and brake hub 14 is 130 brake hubs, the rule of interior hexagonal flush end holding screw 15
Lattice are M8X5, and the specification of slotted nut 17 is M16X1.5, and axle 18 is 130 axles, and the specification of soket head cap screw 19 is M6X25.
Design (calculated) load of the present invention：The 250KG in addition to vehicle frame and battery etc.
Manned quantity：2
Motor uses power：48V 650W
