Description
Technical field
The utility model is related to rear axle of scooter, especially a kind of mobility scooter for old people rear axle.
Background technology
As China comes into ageing stage, elderly population can be more and more, while with the development of economy, rural area
Road construction with city also approach it is perfect, it is more environmentally friendly in addition the trip mode of new energy；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 installation, manufacture, the cost of production 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 seperated 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, valence
Lattice cost is higher.
Utility model content
The technical problems to be solved in the utility model is：It is existing there are two types of the deficiency of rear axle in order to solve, one kind is provided and is aimed at
The rear axle of scooter of the elderly's design.
Technical solution adopted by the utility model to solve its technical problems is：A kind of mobility scooter for old people rear axle, including vehicle
Axis, bearing, reduction box, two shaft assemblies in reduction box and differential mechanism, rear bridge tube, brake fixed plate and brake hub, slow down
There is symmetrically arranged casing outside the babinet of case, rear bridge tube is provided in casing, one end and the sleeve interference of rear bridge tube coordinate, after
The other end of bridge tube welds after tube expansion is handled with brake fixed plate, is welded with holder on rear bridge tube, is offered in described sleeve pipe
For the first positioning hole and second location hole of bridge tube after fixation, the axis of first positioning hole is perpendicular to holder, second location hole
Axis perpendicular to first positioning hole axis.
In order to increase casing strength, on the position of described sleeve pipe outer wall surrounding and be staggered first positioning hole and 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.
Preferably, being integrally formed or being welded with symmetrically arranged casing outside the babinet of the reduction box.
The utility model has the beneficial effects that the mobility scooter for old people rear axle of the utility model, by existing two kinds of rear axle shapes
Formula fusion is got up, and had not only had the structure type of integrated rear axle but also had had second of seperated rear axle structure form；The utility model
Bicycle for old people rear axle uses support configurations, and old age is fixed to using holder and bolt when bicycle for old people rear axle is installed on vehicle
On vehicle carriage, it is equivalent to a both sides bridge tube and is hung directly from vehicle frame, the aluminum hull of speed reducer is practical to be not subject to load, rigid in motor
When starting rotation, motor can have the turning moment of circumferencial direction with retarder, in order to prevent rear bridge tube rotation, so casing
It is upper to be fastened using interior hexagonal flush end holding screw, use two interior hexagonal flush end holding screws, angle to be on casing respectively
90 degree are fixed；Bridge tube uses welding form with brake fixed plate after also, cancels original bolt and connects welded property
Increase intensity, while old kickstand distance and brake fixed plate are close, are easily installed, rear bridge tube carries out tube expansion, is convenient for bearing
Gear processing carries out tube expansion processing using root bead plumber's skill, using the above design, is ensureing safety and service life,
So that the cost reduction of entire bicycle for old people rear axle, appearance, which lacks, to be bolted, aesthetics enhancing, integraty enhancing.
