Abstract
The utility model relates to a farm truck gear box with a shift lock mechanism, comprising a gear box shell as well as a declutch shift shaft and a steel ball which are arranged in the shell, wherein, one side of the steel bass is provided with a guide rod; the other end of the guide rod is provided with a locking shaft; the locking shaft is in transmission connection with a clutch pedal through a crank link mechanism. The utility model locks a slide rod by locking the guide rod to make the slide rod incapable of sliding freely so as to prevent the throw-out of gear and pass through the clutch pedal when the gear is shifted, which is simple and flexible to use, safe and reliable in performance and obviously superior to the original shift mechanism.
Description
Technical field
The utility model relates to a kind of farm vehicle change speed gear box that has shifting retaining mechanism.
Technical background
At present, agriculture truck is in farm work and short-distance transportation, because that the user loads is more, the load that the part parts are subjected in the change speed gear box is bigger, is easy to make gear can not correct engagement to cause out of supplyly, and this phenomenon is more obvious when heavy duty is climbed.In addition, farm vehicle needs buty shifting owing to constantly adjust moving velocity in the process of moving, occurs the not in place and random shelves of engage a gear phenomenon sometimes.These phenomenons all can influence the correct use of farm vehicle, cause a serious accident sometimes, even can cause the generation of personal safety accident.And traditional farm vehicle gear shift mechanism can't overcome above-mentioned phenomenon.Therefore no matter be user or manufacturer, all press for and develop a kind of novel agricultural car gear shift mechanism, promptly can prevent to take off, random shelves that easy operating again, and can not increase too big cost is so that meeting the market requirement better.
Summary of the invention
The purpose of this utility model provides a kind ofly can effectively prevent anti-avulsion, random shelves, and easy operation is flexible, and reasonable price, is applicable to the farm vehicle change speed gear box that has shifting retaining mechanism of various vehicles at dependable performance.
For achieving the above object, the utility model adopts following technical scheme:
The farm vehicle change speed gear box that has shifting retaining mechanism described in the utility model, comprise gear box casing, be installed in declutch shift shaft and steel ball in the housing, it is characterized in that: a side of steel ball has guide rod, the other end of guide rod has lock shaft, and lock shaft is in transmission connection by piston crank mechanism and pedal of clutch.
Have pull back spring on the guide rod.
Thereby the utility model can not be free to slide slide bar by pinning guide rod locking slide bar, prevents that gear is out of supply; Pass through pedal of clutch during gearshift.Use simple and easy flexibly, performance is safe and reliable, obviously is better than former gear shift mechanism.
Description of drawings
Fig. 1 is the local structure scheme drawing of an embodiment of the present utility model;
Fig. 2 is that the B of Fig. 1 is to structural representation;
Fig. 3 is the A-A cutaway view of Fig. 1.
The specific embodiment
As shown in drawings, the farm vehicle change speed gear box that has shifting retaining mechanism described in the utility model is on the basis of traditional change speed gear box, a rocking arm 2 that can be in transmission connection with pedal of clutch is set; rocking arm 2 connects lock shafts 1, and lock shaft 1 is pressed on the guide rod 3, and spring 4 is sleeved on the guide rod 3; guide rod 3 is pressed on steel ball 5 in the groove of declutch shift shaft 6; make slide bar 6 stationkeeping, can not be free to slide, thereby realizes the locking of gear.Gear shift finishes, and clutch pedal lifts, and lock shaft 1 sets back again, gear locking.Under peacetime state, spring 4 plays the effect that improves gear shift feel and Location guide 3.
