Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
It should be noted that " connection " described herein and the word for expressing " connection ", such as " being connected ",
" connected " etc., was both directly connected to including a certain part with another part, also passed through miscellaneous part and another portion including a certain part
Part is connected.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.
As Figure 1-Figure 8, a kind of two-speed gearbox embodiment, including casing, hydraulic motor and power transmission shaft are disclosed
A, power transmission shaft b, gear a, gear b, gear c, gear d, the electromagnetic clutch that is used in combination organize a, electromagnetic clutch and move group surely
A, electromagnetic clutch brush, the electromagnetic clutch being used in combination organize b, electromagnetic clutch dynamic group b, power transmission shaft a and are arranged on machine surely
It is connected by bearing a and bearing b in shell and with casing, gear a and gear b, hydraulic motor transmission transmission is connected with power transmission shaft a
Axle a is rotated, and power transmission shaft a travelling gears a and gear b are rotated；Power transmission shaft b is output shaft, and it passes through bearing c and bearing f and casing
Connection, gear c is connected by bearing d with power transmission shaft b, and gear d is connected by bearing e with power transmission shaft b, gear c and electromagnetic clutch
The dynamic group a of device is connected by hexagon socket head cap screw b, and gear d is connected by hexagon socket head cap screw e with the dynamic group b of electromagnetic clutch, electromagnetic clutch
