Description
Technical field
The utility model is related to resistance wheel device more particularly to a kind of left-right telescopic Spinning resistance devices.
Background technology
Existing market Spinning resistance device mostly uses traditional structure, and traditional structure is using friction sponge as dynamic single
The resistance device of vehicle increases resistance as shown in Figure 1, this structure by increasing the normal pressure between sponge and Spinning front-wheel
Larger to sponge abrasion, resistance device service life is short, after the shrapnel pushing for a long time for simultaneously supporting sponge, will produce deformation,
It influences to adjust Spinning resistance device.
Utility model content
The utility model provides a kind of left-right telescopic Spinning resistance to solve the above-mentioned deficiency of the prior art
Device.
The above-mentioned purpose of the utility model is realized by technical solution below：A kind of left-right telescopic Spinning resistance
Power apparatus, it is characterised in that：Including two controller, motor and left and right expansion screws, the axis connection of the motor has worm screw, institute
It states expansion screw inner end and is equipped with screw thread, the screw thread is engaged with worm screw；The expansion screw outboard end is connected with vertical consolidate
Fixed board, the fixed plate inside are fixed with FERRITE CORE, magnetic induction loop, the magnetic induction loop position are wound on FERRITE CORE
In Spinning front-wheel both sides；The motor and magnetic induction loop are connected to controller, and controller is adjusted equipped with coil current
Switch and motor control switch；The motor is fixed on Spinning vehicle frame, and the expansion screw is mounted on sliding sleeve, sliding sleeve
It is fixed on Spinning vehicle frame.
The operation principle of the utility model：When motor rotates forward, expansion screw is overhanging；When motor reversal, expansion screw
Inside contract, rotating forward the size of current of reversion and magnetic induction loop by controlling motor controls drag size, when rotating forward magnetic induction loop with
The spacing of front-wheel becomes larger, and resistance reduces；The spacing of magnetic induction loop and front-wheel reduces when reversion, and resistance increases.Meanwhile controller
Coil current regulating switch tunes up the electrical current of magnetic induction loop, increases resistance；Turn electric current down, resistance becomes smaller.
The utility model compared with prior art the advantages of be：The utility model can by the size of current of control coil come
Drag size is controlled, also drag size can be controlled by adjusting the spacing between magnetic induction loop and front-wheel, prevent using friction
The drawbacks of sponge.
Description of the drawings
Fig. 1 is the structural schematic diagram of traditional Spinning resistance device.
Fig. 2 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described in further detail with reference to embodiment.
As shown in Figure 1 and Figure 2, a kind of left-right telescopic Spinning resistance device, including controller 1, motor 2 and left and right
The axis connection of two expansion screws 3, the motor 2 has worm screw 4,3 inner end of the expansion screw to be equipped with screw thread 5, the screw thread 5
It is engaged with worm screw 4；3 outboard end of the expansion screw is connected with vertical fixed plate 6, and 6 inside of the fixed plate is fixed with iron oxygen
Body magnetic core 7 is wound with magnetic induction loop 8 on FERRITE CORE 7, and the magnetic induction loop 8 is located at 9 both sides of Spinning front-wheel；It is described
Motor 2 and magnetic induction loop 8 are connected to controller 1, and controller 1 is equipped with coil current regulating switch 10 and motor control switch
11；The motor 2 is fixed on Spinning vehicle frame, and the expansion screw 3 is mounted on sliding sleeve 12, and sliding sleeve 12 is fixed on innervation
On bicycle vehicle frame.
The operation principle of the utility model：When motor rotates forward, expansion screw 3 is overhanging；When motor reversal, expansion screw
3 inside contract, and rotating forward the size of current of reversion and magnetic induction loop 8 by controlling motor 2 controls drag size, magnetic induction loop when rotating forward
8 become larger with the spacing of front-wheel 9, and resistance reduces；Magnetic induction loop 8 and the spacing of front-wheel 9 reduce when reversion, and resistance increases.Meanwhile it controlling
The coil current regulating switch of device 1 processed tunes up the electrical current of magnetic induction loop 8, increases resistance；Turn electric current down, resistance becomes smaller.
The above specific embodiments are only exemplary, is to preferably make skilled artisans appreciate that originally
Patent, be not to be construed as include to this patent range limitation；As long as appointing according to made by spirit disclosed in this patent
How with change or modification, the range that this patent includes is each fallen within.
