Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of auto-manual two-way clutch of the utility model braking deceleration mechanism, by 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: described 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 integrated in the auto-manual two-way clutch brake retarder 4; Described 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 is symmetrical on the star-wheel 13 of shift fork 10 both sides and the star-wheel 13 between the sleeve 9 installs a pair of 12, two pairs of rollers 11 of spring with roller 11 and is separately positioned on the inner both sides of shift fork (10).
In order further to improve performance of the present utility model, the auto-manual two-way clutch brake retarder 4 in radially corresponding sleeve 9 positions is equipped with hand automatic switching control equipment 3.Described star-wheel 13 is a hexagonal prism, and with 15 combinations of planet accelerator.
Wherein said hand automatic switching control equipment 3 can adopt following composition, consisted of 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 described 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 described switching post 7.
