Embodiment
Below in conjunction with accompanying drawing and through specific embodiment the present invention is made further detailed description, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
As shown in Figure 1; A kind of auto-manual two-way clutch of the present invention braking deceleration mechanism; Brakeless motor 5, brakeless speed reducer 2, auto-manual two-way clutch brake retarder 4 coaxial being formed by connecting; It is characterized in that: said auto-manual two-way clutch brake retarder 4 coaxial being installed between brakeless motor 5 and the brakeless speed reducer 2; The output gear engagement of the main drive gear of brakeless speed reducer 2 and auto-manual two-way clutch brake retarder 4, the bearing of the sun gear of planetary reducer 15 and star-wheel 13 is an one in the auto-manual two-way clutch brake retarder 4; Said star-wheel 13 pass through bearing and bearing is provided with a sleeve 9 outward; Coaxial connection one shift fork 10 of the transmission shaft of brakeless motor 5; This shift fork 10 is upper and lower two of mirror image symmetry in auto-manual two-way clutch brake retarder 4, and shift fork 10 is installed between sleeve 9 and the star-wheel 13; Each mirror image symmetry is installed a pair of 12, two pairs of rollers 11 of spring that have roller 11 and is separately positioned on the inner both sides of shift fork (10) on the star-wheel 13 of shift fork 10 both sides and the star-wheel 13 between the sleeve 9.
In order further to improve performance of the present invention, on the auto-manual two-way clutch brake retarder 4 of radially corresponding sleeve 9 positions, hand automatic switching control equipment 3 is installed.Said star-wheel 13 is a hexagonal prism, and combines with planet accelerator 15.
Wherein said hand automatic switching control equipment 3 can adopt following composition; Constitute by handgrip 6, switching post 7 and returning spring 8; Post 7 is switched in the coaxial fixed installation in the lower end of handgrip 6; The bottom, lower end of said switching post 7 is installed in the sleeve 9 of auto-manual two-way clutch brake retarder 4, and suit is by returning spring 8 on the said switching post 7.
Working principle of the present invention is: shift fork 10 is stirred roller 11 and is driven star-wheel 13 rotations simultaneously, thereby plays gearing, and two roller 11 brakings prevent that brakeless speed reducer 2 is rotated further when stopping; Two roller 11 controls are reversed in the other direction in addition, thereby play the effect of bi-directional braking; Outboard dedicated at sleeve 9 is switched post 7, when this switching post 7 is outwards extracted, can open electric actuator normally with the hand automatic switching control equipment 3 of brakeless speed reducer 2; When switching to auto state, the sleeve 9 of auto-manual two-way clutch brake retarder 4 will no longer rotate, and can only use this moment brakeless motor 5 to drive brakeless speed reducer 2 and rotate.And the axle of star-wheel 13 and the sun gear of planetary reducer 15 are the one manufacturing, in transmission, play the effect of deceleration again.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
