Abstract

A project machine gear shift detector relates to the technical field of derailleur gear shifting operating mechanism. The gear shifting is composed of an operation handle 5, a shift shell 1, a spring fixing loop 2, a spring bolt shaft 3 and a fixing spring 4; wherein the spring fixing loop 2 is connected to the lower of the operation handle 5 and the shift shell 1; the spring bolt shaft 3 is arranged in the spring fixing loop 2; the fixing spring 4 is arranged at one side which is near the shell. The utility model overcomes the deficiencies of a soft shaft shift that operation handle is unconspicuous, guarantees reliability of the soft shaft shift and synchronization with the derailleur and effectively avoids possibilities that inadequate gear shifting or over shifting.

Description

A kind of engineering machinery gear shift mechanorecepter

Technical field

The utility model relates to engineering machinery, particularly the speed-change and gearshift operating mechanism technical field of engineering machinery.

Background technique

Engineering machinery, the flexible axle selector that comprises loader, road roller, grader and other correlation engineering machinery only depends on the positioning device of speed changer in gearshift procedure, wait to determine gear as locating stud or place kick, because flexible axle is flexible transmission component, feel is not obvious when handling thus; If install the gear positioning device additional on the flexible axle selector, then owing to reasons such as flexible axle distortion and axle sleeve gaps, it is asynchronous to form the location again easily, produce promptly that gear shift is not in place, speed change not exclusively puts in place or technological deficiencies such as location.

Summary of the invention

The utility model according to the gear shift feel that exists in the prior art not obvious or gear shift locate nonsynchronous technological deficiency, when a kind of gear shift is provided obvious feel is arranged, realize the device of accurate gear shift location, i.e. engineering machinery gear shift mechanorecepter.

The technical solution that the utility model adopted is: be connected and installed with the spring retainer ring on the housing of position between the Joystick bottom of flexible axle selector and the selector housing, in this retainer ring axis pin of the spring is installed, nearly housing one side of this bearing pin is equipped with the engineering machinery gear shift mechanorecepter that fixing spring is formed.

A gear shift mechanorecepter is installed on the housing at selector Joystick bottom and shell position place at least, also can be a plurality of.

The basic principle of this gear shift mechanorecepter is: install the neutral gear mechanorecepter on the flexible axle selector additional, promptly between gear and gear, as reversing and forward gears, install mechanorecepter additional between bottom gear and the top gear, can play the effect of perception, in gearshift procedure, when the last gear of disengaging is about to enter the position of back one gear, since handle during by the axis pin of the spring sphere pressure spring produce tangible resistance, when having tangible very grave sensation, just indicates hand near needed gear, action can put in place a little again, has guaranteed the synchronism of flexible axle selector and speed changer location.

The beneficial effects of the utility model are: overcome the flexible axle selector and when gear shift, handled the unconspicuous deficiency of feel, guaranteed reliability that selector is handled and with the synchronism of speed changer, avoided gear shift not in place or cross the possibility of location effectively.
