Further, gap length is not less than the smallest cross-sectional length of synchronous belt.
Further, gap length is not less than the width of synchronous belt.
Further, middle studdle right-hand end setting threaded hole, intermediate sleeve centre setting through-hole or setting and centre
Threaded hole of the support rod right-hand end bolt hole with model, chain stay after middle studdle is connected to again by bolt connection intermediate sleeve.
Further, motor is flexibly connected with front support rod by bolt, and motor and middle studdle pass through bolt activity
Connection.
Compared with prior art, the beneficial effects of the utility model are:
When the utility model needs replacing transmission belt, the connection bolt of motor and front support rod need to be only split out, loosens motor
With the connection of middle studdle, while removing intermediate sleeve and exposing gap or middle studdle retraction is made to make middle studdle and rear flat
Vacancy is generated between fork, so make motor drive active synchronization belt wheel with the connection rotary shaft with middle studdle rotation angle
Degree reduces active synchronization belt wheel and passive and synchronous belt wheel distance of shaft centers, covers conveyer belt side single tape respectively across vacancy or gap
In the connection bolt in active synchronization belt wheel and passive and synchronous belt wheel, fastening motor, and then complete the replacement of conveyer belt.This is practical
The novel disassembly and installation program reduced when replacing conveyer belt mitigates workload, while because putting down on the left of middle studdle with rear
Fork is not required to dismantle to be fixedly connected, and guarantees motor accurate positioning, and then ensures the same of active synchronization belt wheel and passive and synchronous belt wheel
Step property, it is ensured that without excessive torque and shearing force when conveyer belt operates, guarantee the use effect of synchronous belt, belt wheel or even motor and complete machine
Fruit and service life.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below
Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model
It encloses.
As shown in Figure 1, a kind of synchronous belt fast replacing structure of motor middle electric vehicle, including rear-wheel 1 and after being derived from
The rear chain stay 3 for keeping motor 2 fixed that 1 central axis two sides extend anteriorly out is taken turns, on rear chain stay 3 from rear to preceding set gradually
Between support rod 4 and front support rod 5, motor 2 is set among middle studdle 4 and front support rod 5, and motor 2 passes through with front support rod 5
Bolt is flexibly connected, and facilitates the disassembly of motor 2, and motor 2 is flexibly connected with middle studdle 4 by bolt, facilitates motor 2 opposite
The loosening of middle studdle 4,1 right side of rear-wheel are arranged passive and synchronous belt wheel 6 along central axis, master are arranged on 2 right side output shaft of motor
Dynamic synchronous pulley 7, active synchronization belt wheel 7 and passive and synchronous belt wheel 6 it is longitudinal it is coplanar, synchronous be arranged, active synchronization belt wheel 7 and by
Transmission belt 8 is set on dynamic synchronous pulley 6, and 4 left side of middle studdle is welded to connect with rear chain stay 3, is not required to dismantle, guarantees motor 2
Accurate positioning, and then ensure the synchronism of active synchronization belt wheel 7 Yu passive and synchronous belt wheel 6.4 right side of middle studdle and rear chain stay
3 detachable flexible connections, 4 right-hand end of middle studdle are provided as the gap 9 of reserved section, and 9 length of gap is not less than synchronization
With 8 width, so that synchronous belt 8 can pass through the gap 9 when disassembling and installing.As shown in Fig. 2, what transmission belt 8 installed
In the case of, gap 9 fills intermediate sleeve 10, and 4 right-hand end of middle studdle is arranged threaded hole 12, through-hole is arranged among intermediate sleeve 10
Or the threaded hole with 4 right-hand end bolt hole of middle studdle with model is set, middle studdle 4 is connected to centre by bolt 11
Chain stay 3 after set 10 is connected to again, makes that 4 right end of middle studdle is firm, positioning is connected to rear chain stay 3.
The specific replacement step of transmission belt is：When needing replacing transmission belt 8, the connection spiral shell of motor 2 Yu front support rod 5 is split out
Bolt, loosens the connection of motor 2 and middle studdle 4, while removing intermediate sleeve 10 and exposing gap 9, makes middle studdle 4 and puts down afterwards
Fork 3 between generate vacancy, make motor 2 drive active synchronization belt wheel 7 with the connection rotary shaft with middle studdle 4 rotation angle
Degree reduces active synchronization belt wheel 7 and passive and synchronous 6 distance of shaft centers of belt wheel, divides 8 side single tape of conveyer belt across vacancy or gap 9
It is not placed in active synchronization belt wheel 7 and passive and synchronous belt wheel 6, fastens the connection bolt of motor 2, and then complete conveyer belt 8 more
It changes.The utility model reduces disassembly and installation program when replacement conveyer belt 8, mitigates workload, while because of middle studdle 4
Left side is to be fixedly connected with rear chain stay 3, is not required to dismantle, and guarantees 2 accurate positioning of motor, and then ensure active synchronization belt wheel 7 and quilt
The synchronism of dynamic synchronous pulley 6, it is ensured that without excessive torque and shearing force when conveyer belt 8 operates, guarantee synchronous belt 8, belt wheel or even
The using effect and service life of motor and complete machine.
