Description
Technical field
The present invention relates to a kind of accessory improvement of loading machine steering machine, especially relate to a kind of loading machine steering machine with adjustable speed ratio device.
Background technology
The steering box of loader adopts all-hydraulic structure to make, this steering box in use has the impact with the rotating speed height of steering pump to beat the problem of orientation angle change generation size, namely steering pump is when high rotating speed, the direction gyration rotating steering box is larger than steering pump slow-revving direction gyration, so just cause loader direction when running at high speed unstable, need again twirl bearing circle when operation, make chaufeur operationally very uncomfortable.
Summary of the invention
The object of this invention is to provide a kind of loading machine steering machine with adjustable speed ratio device, having which solved existing steering box direction when running at high speed unstable, needing again twirl bearing circle when operation, made chaufeur operationally very uncomfortable.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals.
The invention discloses a kind of loading machine steering machine with adjustable speed ratio device, by steering handwheel, deflecting bar, drive gear set, output gear wheels, shift fork, steering box forms, it is characterized in that described deflecting bar lower end is connected with driving box, described driving box lower end is fixed with steering box, described deflecting bar inside is fitted with transmission shaft, described transmission shaft top is connected with steering handwheel, described transmission shaft lower end connects the drive gear set being inserted into driving box inside, described drive gear set is respectively equipped with a gear driven wheel, two gear driven wheels, also output shaft is fitted with in described driving box, described output shaft is respectively equipped with a gear output gear, two gear output gears, described output shaft is set with output gear wheels, described output gear wheels are set with shift fork, described output shaft lower end is connected with steering wheel rotating shaft, a gear driven wheel in described drive gear set, two gear driven wheels realize keeping off with on output gear wheels output gear or two and keep off output gear by stirring of shift fork and to be meshed transmission.
As preferably, it is 1:1 that a described gear driven wheel and keeps off output gear transmitting ratio, and described two keep off driven wheels and two, and to keep off output gear transmitting ratio be 1:2.
The invention provides a kind of loading machine steering machine with adjustable speed ratio device, when loader is when running at high speed, a gear driven wheel and one can be made to keep off output gear be meshed by stirring shift fork, transmission ratios is made to be 1:1, realize the stability contorting in direction, when loader is in operation, can by stir shift fork make two gear driven wheels and two keep off output gear be meshed time, transmission ratios is made to be 1:2, make people can steering wheel rotation at a slow speed, make steering box twirl, achieve loader and beat direction pulsation-free effect when running at high speed, can slow steering wheel rotation when operation, chaufeur is made well to control the operation ease in direction.
