Abstract
The invention relates to a novel speed change control mechanism of a steering wheel tractor. A speed change base is mounted on a speed changing box of the steering wheel tractor, and a primary gear shift lever is connected with a primary speed change control lever through a crossed shaft universal coupling. The primary speed change control lever comprises a bending section and a horizontal section. The horizontal section of the primary speed change control lever is sleeved with a primary speed change control lever sleeve, a secondary speed change pull rod is mounted above the front section of the primary speed change control lever sleeve, and a secondary speed change control handle is welded to the right side of the rear end of the primary speed change control lever sleeve. The bending section of the primary speed change control lever is pulled, the crossed shaft universal coupling is used for driving the primary gear shift lever, and accordingly gear increasing and decreasing can be achieved. The secondary speed change control handle is pushed forwards or pulled backwards, and high speed and low speed conversion can be achieved by the aid of the secondary speed change pull rod. The novel speed change control mechanism of the steering wheel tractor is simple in structure, good in operability, high in safety and low in cost.
Description
Technical field
The invention belongs to tractor technical field, specifically the mechanism that main shift and secondary speed-changing operating handle just can be realized steering wheel type tractor increasing, downshift and high, low speed conversion is pulled in a kind of dependence.
Background technique
In general, steering wheel type tractor refers to by hand tractor and forms by increase operator cabin, the transformation of change steering mode, original gear does not change, main shift lever, secondary speed change lever and speed change lever clamshell integral body stretch in operator cabin, handle the main shift lever be placed in I-shaped panel and attached secondary speed change lever to realize increasing, downshift and high, low speed conversion.During tractor steering, stretch into the main shift lever of operator cabin, secondary speed change lever and the speed change lever clamshell integral left right side and rock, to driver, make troubles.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Novel steering wheel type vehicle running operation protector, main shift lever, secondary speed change lever and speed change lever clamshell do not need integral body to go deep into operator cabin, and main shift, secondary speed-changing operating handle are pulled in dependence just can realize steering wheel type tractor increasing, downshift and high, low speed conversion.
The present invention solves the problems of the technologies described above with following technological scheme: a kind of Novel steering wheel type vehicle running operation protector, at the bottom of comprising speed change seat, main shift lever, cross-axle universal shaft coupling, main shift sleeve pipe, secondary speed-changing operating handle, main shift and secondary speed-changing pull rod;
Described selector gear is arranged on steering wheel type tractor gearbox at the bottom of by speed change seat, main shift lever connects main shift by cross-axle universal shaft coupling, main shift comprises bending section and horizontal segment, the main shift sleeve pipe of horizontal segment overcoat of main shift, secondary speed-changing pull rod is installed in the leading portion top of main shift sleeve pipe, and secondary speed-changing operating handle is welded on right side, main shift sleeve pipe rear end;
The bending section of pulling main shift, drives main shift lever by cross-axle universal shaft coupling, can realize gear increasing, subtract; Push away forward or toward the secondary speed-changing operating handle of post-tensioning, by secondary speed-changing pull rod, can realize high, low speed conversion.
The present invention is simple in structure, and good operability is safe, and cost is low.
