Abstract
The utility model discloses a loader soft-axle variable-speed operating mechanism. A distributing valve rod of a variable-speed operating valve is connected with a variable-speed soft axle which is connected with a rack, and an axle gear fixedly connected with an operating handle is engaged with the rack. The variable-speed operating handle is rotated, the axle gear is rotated with a definite angle, the rack is driven to move a definite range, the distributing valve rod of the variable-speed operating valve is moved to a corresponding position through the variable-speed soft axle, and then a variable-speed box is hung on a corresponding gear. The utility model can realize remote operation and have a neutral position locking function. The loader soft-axle variable-speed operating mechanism has the advantages of simple structure, convenient operation, reliable work and easy arrangement on a loader.
Description
The utility model relates to a kind of selector gear that is used on the loader.
Homemade 30 types, 40 types, 50 type loaders are basic identical in the transmission configuration, promptly all are to adopt 2 D Drives 1 of the tor-con of two turbines and band overriding clutch to retreat the planetary transmission of shelves, and therefore the selector gear that is adopted is also basic identical.Selector gear commonly used on the homemade loader of these models is a kind of spatial linkage, complex structure, and the bigger and difficult layout of the influence that arranged by the loader complete machine, and do not adopt the measure of neutral gear locking.
The purpose of this utility model is exactly develop at above-mentioned deficiency a kind of simple in structure, be easy to layout on the loader, control comfort and have the loader selector gear of neutral gear latch functions.
The purpose of this utility model is achieved in that on the distribution valve rod of speed change maneuvering valve and is connected with the speed change flexible axle that the speed change flexible axle is connected with tooth bar, is fixed on the engagement of bar handle bonded assembly shaft gear and tooth bar.Described tooth bar is to be enclosed within the column, is provided with bearing pin in the neutral gear hole that is headed into tooth bar by spring force in column and the tooth bar Neutral Position part that adapts.Rotate the speed change bar handle, shaft gear turns over certain angle, drives tooth bar and moves certain stroke, makes the distribution valve rod of speed change maneuvering valve move to corresponding position by the speed change flexible axle again, makes change speed gear box hang up corresponding gear.When hanging up neutral position, with the neutral gear Locking Device tooth bar can not be moved, then the speed change bar handle can not rotate and is unlikely to mistake and hangs the trip stop that other gear or other factors cause.And adopt the flexible axle ways of connecting, can easily bar handle be placed in the desired position.
The utility model is compared with prior art: 1. is easy on loader, arrange, and easy for installation; 2. simple in structure, control comfort; 3. the neutral gear latch functions is arranged and be beneficial to temporary term stop safety.
The utility model will be further described below in conjunction with accompanying drawing.
Accompanying drawing 1 is the view of utility model
Accompanying drawing 2 is that A is to view.
Accompanying drawing 3 is that B is to view.
Accompanying drawing 4 is the view of neutral gear Locking Device.
The utility model includes spring cotter 1, bearing pin 2, bar head 3, bolt 4, packing ring 5, speed change flexible axle 6, speed change flexible axle erection support 7, joint 8, column 9, tooth bar 10, ball-bearing casing 11, holding screw 12 bar handles 13, nut 14, shaft gear 15, gear indicator collet 16, back-up ring 17, outside framework oil seal 18, pad 19, screw 20, dust-break lid 21, block 22, back-up ring 23, neutral gear Locking Device 24, clips 25, cushion block 26, bolt 27, packing ring 28, packing ring 29.Being fine into bearing pin 30, bearing 31, screw 32, spring 33, pin 34, having handled knob 35 of neutral gear Locking Device 24.
Be connected with speed change flexible axle 6 on the distribution valve rod of speed change maneuvering valve, speed change flexible axle 6 is connected with tooth bar 10, is fixed on bar handle 13 bonded assembly shaft gears 15 and tooth bar 10 engagements.Described shaft gear 15 is to be installed in and tooth bar 10 position engaged with bearing 11.Described tooth bar 10 is to be enclosed within the column 9, is provided with bearing pin 30 in the neutral gear hole that is headed into tooth bar 10 by spring force in column 9 and the tooth bar Neutral Position part that adapts.Described spring force is meant that being enclosed within bearing pin 30 springs 33 outer, that be installed in the bearing 31 produces.
Bearing pin 30 is provided with pin 34, and bearing 31 is provided with the inverted draw cut that can block pin 34, when bearing pin 30 when spring force heads in the neutral gear hole of tooth bar 10, tooth bar 10 can not move.
On shaft gear 15, be fixed with gear indicator collet 16, in order to the indication gear.
The utility model is fixed on gear indicator collet 16 on the shaft gear 15 by holding screw 12.By clips 25 and cushion block 26, bolt 27, packing ring (28,29) selector gear is installed on the column of loader direction machine, and can adjusts the distance of selector gear by clips 25 and cushion block 26 to direction machine column.By bar head 3 the distribution valve rod of speed change flexible axle 6 with the speed change maneuvering valve linked up.By bolt 4, packing ring 5 speed change flexible axle 6 erection supports 7 are contained on the gear box.
The principle of work of this utility model is as follows.
The principle of work of neutral gear Locking Device 24: 35 mention bearing pin 30 by handling knob, and turn over certain angle, pin 34 is stuck in the inverted draw cut of bearing 31, tooth bar 10 can move, and makes selector gear can carry out variable speed operation, and this moment, the neutral mechanical brake was inoperative.When change speed gear box is in Neutral Position, 35 mention bearing pin 30 by handling knob, and turn over certain angle, pin 34 is stuck in the kerve of bearing 31, then in the slotted eye of bearing pin 30 insertion tooth bars 10 (seeing accompanying drawing 2), tooth bar 10 can not move, and also is that selector gear can not carry out variable speed operation, at this moment neutral gear mechanical brake locking.
The principle of work that speed change is handled: rotate the position of bar handle 13 to 16 indications of gear indicator collet, shaft gear 15 turns over corresponding angle, make tooth bar 10 move corresponding displacement by gear, rack for transmission, the speed change flexible axle 6 that is fixed on the tooth bar 10 also moves corresponding displacement, the speed change maneuvering valve that links to each other with speed change flexible axle 6 distributes valve rod also to move corresponding displacement, makes change speed gear box hang up corresponding gear.
