Abstract
The utility model relates to an operating mechanism for automobiles, which comprises a casing for a speed-changing operating chamber body, grade-changing operating lever. A damping localizer is arranged between the casing and the grade-changing operating lever. The utility model has the advantages of reasonable simple structure, convenient operation, and safety.
Description
The utility model relates to a kind of automobile operation mechanism, particularly a kind of agricultural vehicle shifting control mechanism for gear box.
That shown in Figure 1 is the agricultural vehicle shifting control mechanism for gear box figure of present use, and 1 is that gear box casing, 2 is that shift control cabin housing, 3 is that gear locating piece, 4 is that gear locating dowel pin, 5 is that gear steady arm pull bar, 6 is that shift joystick, 7 is a gear steady arm pull bar handgrip.In chaufeur was being operated along the shelves process, when joystick 6 became shuttle gear shift, chaufeur must at first be carried the position with pull bar handgrip 7, drive locating dowel pin 4 by pull bar 5 like this, make it break away from locating piece 3, play the purpose of pulling pin, could handle gear-change hand lever 6 conversion then and fall along gear.There is following weak point in such structure design: 1. complex structure; 2. many actions are with regard to many error chances, thereby safety is low; 3. it is big to handle inconvenience and manipulated variable, increases driver fatigue.
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art part, and a kind of simple and reasonable, control comfort and safe and reliable agricultural vehicle shifting control mechanism for gear box are provided.
The purpose of this utility model is achieved in that
A kind of agricultural vehicle shifting control mechanism for gear box comprises speed change control cabin body housing, shift joystick, between said shift joystick and speed change control cabin body housing damping positioner is set.
Said damping positioner comprises stage clip, compression spring sleeve, and said compression spring sleeve free skating is enclosed within on the speed change control cabin body housing, and said stage clip places in the compression spring sleeve, and compression spring sleeve is beared down on one on the shift joystick.
Said shift joystick and compression spring sleeve contact portion are spirogyrate.
Embodiment elaborates below in conjunction with the accompanying drawing utility model.
Fig. 2 is the embodiment part sectional view.An important performance of car gear shifting operating mechanism is that gear must be stablized, and once a gear is set, then can not change without this gear of operation, especially can not be changed to reverse gear along shelves.For guaranteeing this point, prior art is to have adopted structure shown in Figure 1.The utility model is through a large amount of Creative Design and test, taking into full account on the basis that requires such as easy to operate, simple in structure, and the structure that has adopted a damping positioner is to replace original structure.Specifically, be between shift joystick 6 and shift control cabin body housing 2 damping positioner to be set, the effect of this damping positioner is to make the shift joystick to be subjected to a resistance, makes it can stablize gear, and make transforming gear can stablize transition, unlikely appearance sudden change situation.The version of damping positioner can be varied, and the damping positioner in the present embodiment comprises stage clip 8, compression spring sleeve 9, and the compression spring sleeve free skating is enclosed within on the speed change control cabin body housing, and stage clip places in the compression spring sleeve, and compression spring sleeve is beared down on one on the shift joystick.Preferably two above-mentioned damping positioners are set in shift joystick bilateral symmetry.In addition; The shift joystick becomes spirogyrate in the partial design that contacts with compression spring sleeve, to increase damping.
Compared with prior art, the utlity model has following advantage: adopted damp type Locator, when shift is handled, as long as direct control shift control stick, and gear Automatic stabilisation, the shift transition is stable, with the sample of the utility model design through bench test And the test use on personal automobile, its performance meets standard-required, effect fully Well. Thereby the selector device that the utility model provides is simple and reasonable, handles Convenient, and safe and reliable.
