Description
Technical field
The utility model belongs to speed reducer field, is specifically related to a kind of reverse gear apparatus for tricycle speed reducer.
Background technique
Reversing gear is the gear realizing car load fallback function, and its direction of travel is contrary with forward gear.There is a lot of reverse gear apparatus in the prior art, but mostly complex structure, to take installing space comparatively large, makes a lot of dilly, as tricycle, electric motor car etc. cannot be suitable for.For solving this technical problem, being badly in need of improving existing reverse gear apparatus, making it possible at dilly, as tricycle, electric motor car etc. are installed.
Model utility content
It is simple, easy to use that the utility model object is to provide a kind of structure, can have the reverse gear apparatus for tricycle speed reducer of little saving installing space.
For realizing above-mentioned technical purpose, use following technological scheme:
For a reverse gear apparatus for tricycle speed reducer, comprise power input device, reverse gear transmission, output shaft and casing.Input device comprises drive bevel gear, driven wheel of differential and splined shaft, and drive bevel gear provides power by motor, and driven wheel of differential engages with drive bevel gear; Driven wheel of differential to be arranged on splined shaft and to coordinate with splined shaft, to ensure splined shaft and driven wheel of differential synchronous axial system; Reverse gear transmission comprises back fork, reverse gear and reverse gear gear, and reverse gear is ring, its inner circle and splined shaft is slidably matched, cylindrical is provided with annular groove and the driving gear that reverses gear; It is outer and engage with the driving gear that reverses gear that reverse gear gear is arranged at splined shaft.Back fork to be arranged on casing and to coordinate with annular groove, makes reverse gear can follow back fork motion; When back fork moves to reverse gear gear direction, reverse gear follows back fork to the motion of reverse gear gear direction, reverse gear driving gear and reverse gear Gear Contact time, the driving gear that reverses gear drive reverse gear gear.Output shaft is provided with the driven gear that reverses gear, and reverse gear driven gear and reverse gear gears meshing, and power input device, reverse gear transmission and output shaft are all arranged in casing.
The utility model beneficial effect is: the utility model structure is simple, easy to use, by reverse gear, reverse gear gear and the driven gear that reverses gear being combined, the utility model is made to realize gear reversing function in less installing space.The utility model is more applicable for as the dilly such as tricycle and electric motor car.
