Abstract
The utility model is related to chain stay components after a kind of band built-in motor, including rear chain stay, motor and gearbox；There is axle sleeve, rear end to be provided with axis ear for chain stay front end after described；It is characterized in that：Chain stay is provided with angle bar in front end afterwards, and the motor and gearbox integrally lock on angle bar.The utility model has the characteristics that simple structure and reasonable design, synchronism are good；Motor and gearbox can be moved with subsequent chain stay, holding and the reliable of rear wheel drive and stable, reduction energy loss, and conveniently mating with conventional motorcycle.
Description
Technical field：
The utility model belongs to battery-operated motor cycle field, more particularly to chain stay component after a kind of band built-in motor.
Background technology：
Existing electric bicycle and battery-operated motor cycle, mostly use greatly wheel hub motor, have it is simple for structure, good integrity is exempted from
The characteristics of safeguarding, but be exactly that torsion is small, load-carrying and climbing capacity are weak, and high energy consumption there is also deadly defect.And it uses external
Motor using high-speed electric expreess locomotive through gearbox speed governing, and reaches promotion twisting force, this mainstream for also becoming battery-operated motor cycle is told
It asks.External motor sets scheme in generally using, and utilizes engine space, and motor and gearbox weight originally in the middle part of vehicle frame
It can equilibrium assignment.How motor and gearbox fixed, can be consistent with trailing wheel spacing, the scheme of power transmission loss is avoided,
For the object of the utility model research.
Invention content：
The purpose of this utility model is that a kind of motor of design and gearbox lock in rear chain stay front end, keeps the band of synchronism
Chain stay component after built-in motor.
What technical solutions of the utility model were realized in：Chain stay component after a kind of band built-in motor, including rear chain stay, electricity
Machine and gearbox；There is axle sleeve, rear end to be provided with axis ear for chain stay front end after described；It is characterized in that：Chain stay is set in front end afterwards
It is equipped with angle bar, the motor and gearbox integrally lock on angle bar.
The motor and gearbox are the integrated design, and motor is encapsulated in gearbox；Gearbox surface is provided with bolt
Hole ear, by bolt locking on angle bar.
Chain stay corresponds to and is provided with stretcher fixed ear on the fork arm of chain side after described.
The utility model has the characteristics that simple structure and reasonable design, synchronism are good；Motor and gearbox can be with then putting down
It pitches and moves, holding and the reliable of rear wheel drive and stable, reduction energy loss, and it is conveniently mating with conventional motorcycle.
Description of the drawings：
The utility model is described further with reference to specific legend：
Fig. 1 is chain stay component diagram after band built-in motor
Fig. 2 is chain stay component decomposition diagram after band built-in motor
Fig. 3 is schematic diagram after chain on rear chain stay
Wherein
1-rear 11-axle sleeve of chain stay 12-axis, 13-angle bar of ear
14-fixed ear 2-gearbox, 21-bolt hole, 3-bolts of ear
4-5-chains of stretcher
Specific implementation mode：
Referring to FIG. 1, FIG. 2 and FIG. 3, chain stay component after band built-in motor, including rear chain stay 1, motor and gearbox 2；After put down
1 front end is pitched to be provided with axis ear 12 with axle sleeve 11, rear end, be additionally provided with angle bar 13 in front end；The motor and gearbox 2 are whole
Body locks on angle bar 13 so that and it is whole to follow rear wheel movement, when especially encountering uneven road surface, rear shock absorber can be followed in due course
It swings up and down, the transmission efficiency without influencing chain.In addition, being provided with tensioning on the fork arm that rear chain stay 1 corresponds to chain side
Device fixed ear 14, to install chain tensioning device 4, to tighten chain 5 in due course, such as Fig. 3.
The motor and gearbox 2 are the integrated design, and motor is encapsulated in gearbox 2；2 surface of gearbox is provided with spiral shell
Keyhole ear 21, by the locking of bolt 3 on angle bar 13.
