Description
Technical field
The present invention relates to a kind of vehicle component, especially relate to the shifting-fork gear-shifting assembly of a kind of farm machine gearbox.
Background technology
Along with the raising of people's living standard, private car is increasingly becoming the indispensable vehicles of life at home.The demand of vehicle is constantly increased by people, it is desirable to also improve constantly, and corresponding vehicle research and development technology is also improving constantly.Gearshift assembly is ingredient important in vehicle speed variation system, and technology reaches its maturity, and structure is increasingly sophisticated, and function is the most powerful, and performance is the most stable.
Farm machinery also has corresponding speed change request, but compared to vehicular traffic, it is desirable to relatively low.Meanwhile, on the premise of ensureing gearshift performance, cost factor should also be taken into full account.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in construction, lower-cost shifting-fork gear-shifting assembly, it is adaptable to farm machine gearbox, and the problem solving farm machine gearbox gear slippage and location.
For solving above-mentioned technical problem, the technical scheme is that
A kind of shifting-fork gear-shifting assembly, including gearshift pivoted arm, axle sleeve, pivoted arm seam, shift fork axle and shift fork, wherein pivoted arm seam is welded to form by rotating shaft, Z-type pivoted arm connecting plate and the little axle of pivoted arm, rotating shaft is flexibly connected with gearshift pivoted arm, the little axle of pivoted arm is flexibly connected with shift fork, described shift fork is movably connected on shift fork axle, pulls gearshift pivoted arm and drives pivoted arm seam to rotate, and then drives shift fork sliding on shift fork axle.
Preferably, described shift fork includes pitching body, spacing hole post, axis hole post and groove composition, and spacing hole post is positioned at above fork body, and axis hole post and spacing hole post are decussation, and groove is embedded on axis hole post.
Preferably, described gearshift pivoted arm uses Z-type structure, pull space more greatly, more laborsaving.
Preferably, the rotating shaft of described pivoted arm seam has been got on the bus U-shaped ring, and in U-shaped ring, assembling O RunddichtringO seals, and it is milling flat that rotating shaft is connected one end with pivoted arm of shifting gears.
Preferably, limited location U groove on described shift fork axle, plays gearshift limit effect, the equal chamfering in U groove both sides, makes gear shift operation be easier to.
Preferably, described shift fork spacing hole post is built with stage clip and steel ball.
Beneficial effects of the present invention: driving pivoted arm seam by pulling gearshift pivoted arm, the little axle of pivoted arm of pivoted arm seam slides in the groove of shift fork, and then driven gear moves on splined shaft.It is furnished with stage clip and steel ball in the spacing hole post of shift fork, with the spacing U slot fit on shift fork axle, plays the effect that gearshift is spacing；Gearshift pivoted arm use Z-type structure so that gearshift space more greatly, more laborsaving.
