Abstract
The utility model discloses a clutch operating mechanism of a tractor. The clutch operating mechanism of the tractor comprises a foot lever, a clutch shifting fork, a middle swing arm, a swing arm fulcrum, a pull arm, a pull rod and a returning spring. The swing arm can rotate along with the swing arm fulcrum, and the pull arm enabling the swing arm to swing is hinged between the tail portion of the foot lever and the free end of the swing arm. The pull rod enabling the clutch shifting fork to swing is arranged between the swing arm and the clutch shifting fork. The returning spring is arranged between the outer side end portion of the clutch shifting fork and a machine body. According to the clutch operating mechanism of the tractor, the simple four-bar linkage principle is utilized, the transmission ratio is evenly distributed, so that the operating transmission force of the operating mechanism synchronously varies along with a disc spring of the clutch so as to achieve the aims of reducing the operating force and effectively separating the clutch, and the maximum operating force of the clutch can be effectively reduced. In addition, the clutch operating mechanism of the tractor is simple in structure, easy and convenient to operate, stable in operation, convenient to overhaul, easy to implement, and is good in promotion value.
Description
Technical field
The utility model relates to agricultural vehicle manufacturing technology field, relates in particular to a kind of tractor clutch operating mechanism.
Background technique
the most of operating device that adopts simple lever construction of present tractor, namely driving a connecting rod by pedal pulls clutch yoke to do in order to controlled clutch, the velocity ratio of this operating mechanism is directly proportional, be linear distribution, the clutch steering force increases synchronous the increase with the pressure of clutch dish spring, in the tractor practical operation, the steering force that clutch needs is large and unstable, clutch often separates not thorough, particularly particularly evident concerning the tractor that adopts the double clutch that the interlock of main clutch and side clutch handles, the inconvenience of having brought very large potential safety hazard and having used for the operation of tractor.So, develop a kind of steering force that can reduce tractor clutch and effectively the tractor clutch operating mechanism of cut-off clutch be desirability.
The model utility content
The purpose of this utility model is to provide a kind of can reduce the steering force of tractor clutch and the effective tractor clutch operating mechanism of cut-off clutch.
the purpose of this utility model is to realize like this, the utility model comprises can be with the treadle of treadle fulcrum rotation and the clutch yoke of separable clutch, swing arm in the middle of described operating mechanism also comprises, the swing arm fulcrum, torque arm, pull bar and Returnning spring, the swing arm fulcrum is arranged on frame, middle swing arm is hinged on the swing arm fulcrum and can rotates with the swing arm fulcrum, be hinged with the torque arm that in the middle of can making, swing arm swings between treadle afterbody and middle swing arm free end, between middle swing arm and clutch yoke, the pull bar that clutch yoke is swung is installed, between the outboard end of clutch yoke and body, Returnning spring is installed.
The utility model adopts simple four connecting rod principles, the mean allocation velocity ratio, make the manipulation driving force of operating mechanism reach with synchronous variation of clutch dish spring the purpose that reduces steering force and effective cut-off clutch, quadratic crank mechanism by middle swing arm interlock has been optimized traditional on-off control mechanism, can effectively reduce the maximum steering force of clutch, and simple in structure, easy and simple to handle, stable, maintenance convenience, easy to implement has promotional value preferably.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
In figure: 1-treadle, swing arm in the middle of 2-treadle fulcrum, 3-, 4-swing arm fulcrum, 5-torque arm, 6-pull bar, 7-clutch, 8-clutch yoke, 9-adjusting nut, 10-fixed plate, 11-Returnning spring, 12-outside thread.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but never in any form the utility model is limited, any change or improvement based on the utility model training centre is done all belong to protection domain of the present utility model.
as shown in the figure, the utility model comprises can be with the treadle 1 of treadle fulcrum 2 rotations and the clutch yoke 8 of separable clutch 7, swing arm 3 in the middle of described operating mechanism also comprises, swing arm fulcrum 4, torque arm 5, pull bar 6 and Returnning spring 11, swing arm fulcrum 4 is arranged on frame, middle swing arm 3 is hinged on swing arm fulcrum 4 and can rotates with swing arm fulcrum 4, be hinged with the torque arm 5 that in the middle of can making, swing arm 3 swings between treadle 1 afterbody and middle swing arm 3 free ends, the pull bar 6 that clutch yoke 8 is swung is installed between middle swing arm 3 and clutch yoke 8, Returnning spring 11 is installed between the outboard end of clutch yoke 8 and body.
during free state, under Returnning spring 11 effects, clutch 7 is sentenced bonding state, when needs cut-off clutch 7, tramp with one's feet and step on bar 1, treadle 1 rotates with treadle fulcrum 2, thereby in the middle of pulling by torque arm 5, swing arm 3 clockwise rotates with swing arm fulcrum 4, simultaneously, swing arm 3 pulls clutch yoke 8 by pull bar 6, under clutch yoke 8 effects, realize the separation of clutch 7, need to make clutch 7 again in conjunction with the time, only need unclamp treadle 1, under Returnning spring 11 effects, clutch yoke 8 automatically reverts to again the home position, clutch 7 reenters bonding state.
Further, described pull bar 6 is processed with outside thread 12 near clutch 7 one ends, clutch yoke 8 ends are processed with diameter greater than the through hole of pull bar 6 external diameters, pull bar 6 passes through hole back-end section adjusting nut 9 is installed, make the length of pull bar 6 adjustable, can further regulate the matching relationship of 7, clutch operating mechanism and clutch.
Preferably, described clutch 7 outsides are installed with fixed plate 10, and the positioning end of Returnning spring 11 is fixed on fixed plate 10.
