Description
Technical field
The utility model is related to the parts of falling electro-tricycle, and in particular to two deflecting rollers are set before one kind, behind
Chain stay after one combined type of a kind of reverse electro-tricycle of driving wheel is set.
Background technology
Reverse electro-tricycle is that front-wheel has right, right each wheel, and trailing wheel has the tricycle of a wheel, wherein, before two
Wheel has turning function, and trailing wheel has driving function by the energy of electric power.With the appearance of national energy-saving emission reduction policy, electric motor car
Use increasingly popularize.The rear chain stay of existing electric motor car is mostly using be fixed as one formula structure, the structure one of its right and left
Cause symmetrically, when re-type is needed, it is necessary to which whole trailing wheel is integrally pulled down, and the trailing wheel of electric motor car is generally one with motor
, when motor breaks down to need repairing, it is necessary to motor is integrally disassembled from vehicle, can be repaired.So at present,
There is tire changing in the chain stay of the electric motor car of the formula that is fixed as one structure, electrical machmary maintenance is inconvenient and single making mould is big, make
The defect of high cost, because reverse tricycle is with respect to for electric motor car, volume is big, and own wt is big, and good stability is repaired
It is more inconvenient, so with greater need for solution above-mentioned technical problem on reverse tricycle.
The content of the invention
Technical solutions of the utility model technical problem to be solved is to provide a kind of combined type of reverse electro-tricycle
Chain stay, solves the re-type inconvenience that reverse tricycle electronic at present is present, inconvenient maintenance, cost of manufacture defect high afterwards.
To realize above-mentioned technical purpose, the technical solution of the utility model is as follows：
Chain stay after a kind of combined type of reverse electro-tricycle, including left and right symmetrical left chain stay and right chain stay, it is left
Chain stay includes left sleeve pipe, left chain stay support arm, the left installation journal stirrup of the only damping of rear center, wherein, left sleeve pipe and left chain stay support arm
It is fixedly connected, left chain stay support arm the inner is fixedly connected the left installation journal stirrup of the only damping of rear center；Right chain stay includes that right sleeve pipe, the right side are flat
Fork support arm, the right installation journal stirrup of the only damping of rear center, wherein, right sleeve pipe is fixedly connected with right chain stay support arm, right chain stay support
Arm the inner is fixedly connected the right installation journal stirrup of the only damping of rear center；Left chain stay and symmetrical the putting of right chain stay are fixed on car by bottom fork axis
On frame, the upper end of the only damping of rear center is hingedly connected at the upper end of vehicle frame back segment, and the lower end of the only damping of rear center is hingedly connected at
The only damping of rear center is left to install on journal stirrup and the right installation journal stirrup of the only damping of rear center.
Using chain stay after the combined type of above-mentioned technical proposal, in tire changing, electrical machmary maintenance, it is only necessary to by bottom fork axis
（One end is to use nut check）Fixing nut unclamp, the hinge axis of the only damping lower end of rear center is unclamped, just can be by left chain stay
Remove, directly just can on the basis of trailing wheel and right chain stay is not removed re-type and maintenance motor；Further, since left chain stay
It is the symmetrical shape in left and right with right chain stay, can be manufactured using same secondary mould, the mould of making is also than fixing one
Body formula structure it is small, mould easily makes, cost reduction, and interchangeability is strong.Certainly, the need for according to installation, it is also possible to individually will
Right chain stay is removed, and its effect is as structural principle.
Further, limit the left journal stirrup of installing of the described only damping of rear center and be arranged on left chain stay support arm the inner bottom, institute
The right journal stirrup of installing of the only damping of rear center stated is arranged on right chain stay support arm the inner bottom.
Because chain stay is formed using the symmetrical left chain stay in left and right and right flat fork combination, the stress at trailing wheel center is acted on
It is larger, bottom fork axis center is delivered to, that is, left chain stay and right chain stay coordinate the stress that contact position is subject to larger, so being arranged to
The only damping of rear center is more suitable for this combined bottom fork, and installation journal stirrup is all disposed within into chain stay support arm the inner bottom, has
Beneficial to the stress deformation that left chain stay and right chain stay coordinate contact position to be subject to is reduced, the space of chain stay bottom is big, after being more convenient to install
The only damping in center.
Technical solutions of the utility model have advantages below compared with prior art：The space of reverse tricycle frame leading portion
Arrangement scope is big, and design model is convenient, and direction standpipe is easily adjusted, changed, applicable vehicle scope is big.
