Description
Technical field
The utility model relates to a kind of steering wheel, especially relates to a kind of band adjustable speed ratio steering wheel.
Background technology
The steering wheel of loader is to adopt all-hydraulic structure to make, this steering wheel in use has the rotating speed height with steering pump to affect the big or small problem of orientation angle variation generation of beating, be that steering pump is when high rotating speed, the direction gyration of rotation direction machine is larger than the slow-revving direction gyration of steering pump, so just caused loader direction when running at high speed unstable, when operation, need again twirl bearing circle, make chaufeur very uncomfortable when work.
Summary of the invention
The utility model provides a kind of band adjustable speed ratio steering wheel, and it is unstable that it has solved existing steering wheel direction when running at high speed, and needs again twirl bearing circle when operation, makes chaufeur very uncomfortable when work.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals.
Band adjustable speed ratio steering wheel of the present utility model, by bearing circle, direction lever, drive gear set, output gear wheels, shift fork, steering wheel forms, be primarily characterized in that described direction lever lower end is connected with driving box, described driving box lower end is fixed with steering wheel, described direction lever inside is fitted with transmission shaft, described transmission shaft top is connected with bearing circle, described transmission shaft lower end connects the drive gear set that is inserted into driving box inside, in described drive gear set, be respectively equipped with a gear driven wheel, two gear driven wheels, in described driving box, be also fitted with output shaft, on described output shaft, be respectively equipped with a gear output gear, two gear output gears, on described output shaft, be set with output gear wheels, on described output gear wheels, be set with shift fork, described output shaft lower end is connected with steering wheel rotating shaft, in described drive gear set one gear driven wheel, two gear driven wheels can be by shift fork stir to realize the transmission that is meshed with one on output gear wheels gears output gear or two gear output gears.
As preferably, a described gear driven wheel is 1:1 with a gear output gear transmitting ratio, and it is 1:2 that described two gear driven wheels and two keep off output gear transmitting ratios.
The band adjustable speed ratio steering wheel that provides of the present utility model, when loader is when running at high speed, can one gear driven wheel be meshed with a gear output gear by stirring shift fork, making transmission ratios is 1:1, realize the stable control of direction, when loader is during in operation, can make two gear driven wheels and two gear output gears while being meshed by stirring shift fork, making transmission ratios is 1:2, make the steering wheel rotation that people can be at a slow speed, make steering wheel twirl, realize loader and when running at high speed, beaten direction pulsation-free effect, slow steering wheel rotation when operation, make chaufeur well control the operation ease of direction.
