Abstract

The utility model relates to a separating safety clutch for a small four-wheeled tractor. The separating safety clutch for a small four-wheeled tractor comprises a casing and an upper cover at the front. A big speed reducing gear is positioned on the left of a fifth shaft. Bearings are positioned on the two shaft ends of the fifth shaft. The right of the fifth shaft is provided with a gear. The big speed reducing gear is sheathed on the fifth shaft emptily, and a winding shaft at one side of the big speed reducing gear is provided with three circular teeth whose distances are equal. A clutch gear is sheathed on the fifth shaft and can move along the axial direction. The clutch gear is clutched with the big speed reducing gear. A clutch spring is sheathed on the fifth shaft between the clutch gear and the gear. A shifting fork is positioned in the shifting fork groove of the clutch gear. The utility model has the advantages that various performances of an original tractor are reserved, the disadvantages existing in the prior art that when a small four-wheeled tractor is uphill or downhill, a bumper disengages are avoided, and the safe performance for the complete appliance is improved. The utility model also has the advantages of novel and simple structure, and stable and reliable performance.

Description

Separating safety clutch for small four-wheeled tractor

The utility model belongs to clutch and makes the field.

Background technique of the present utility model is: it is by shifting from slow to fast that the tractor with small four wheels clutch of selling on the market exists one, because the linear velocity of driven gear is lower than the linear velocity of driving gear, clashes into, weares and teares, cracks a joke so cause gear easily; The 2nd, by shifting from fast to slow, because the linear velocity of driven gear is than the linear velocity height of driving gear, so cause easily that also gear clashes into, weares and teares, cracks a joke; The 3rd, because wearing and tearing can cause the phenomenon of " out of supply automatically ", upper and lower slope " out of supply " causes driving or falls major accident such as slide; The 4th, reduce vehicle service life and safety coefficient; The 5th, the engage a gear inconvenience falls to slip easily in the upward slope gearshift procedure, causes a serious accident.

Purpose of design of the present utility model is: avoid deficiency of the prior art, design a kind of with get rid of the engage a gear difficulty, reduce the gearbox internal gear wearing and tearing, prolong in the case working life of each, in practice, reach whenever and wherever possible engage a gear freely, avoid mechanical wear, improve the tractor with small four wheels separated type security personnel clutch of the Safety performance of tractor.

Design proposal of the present utility model: this separator is to design on five, five big retarding gears, just say singlely, it is not act on five and can be around the gear of five idle running, its side is divided into three teeth that spacing equates around the axle protuberance around circumference, the right side of gear is that its side of pasting gear of clutch gear also has three teeth, just can coincide with three teeth of big retarding gear, its endoporus is the flower pad, its rotation can act on five, and can remove to the right, allow the tooth of big retarding gear and the transposition of teeth that this is taken turns, the right side of clutch gear is a spring, its effect can be pushed clutch gear to the big retarding gear, and that the two is drawn close is identical, the spring right side is the gear of five effect driving wheels, its endoporus is a spline, whole five positions except that dress big retarding gear are the circular shaft, remaining part all is a spline, it is installed on the position of five in former car, five in whole gearbox role be: five big retarding gears are accepted the power of front axle, pass to right side gear clutch gear, pass to five by clutch gear, again by rightmost gearing on the rear axle, on five roundlet wheels a shift fork is housed, can overcome the tension force of the right spring under the active force of shift fork, itself and big retarding gear are threaded off, the output of shift fork effect pull bar is in parallel with the front clutch pedal.

Organization plan: 1, with bearing 2 earlier 1 of peace on five 7 right side, be shaped on gear 6 on five 7; 2, clutch spring 5 is installed on five the left side; 3, five five axis holes by gear box casing are moved from right to left; 4, clutch gear 3 and shift fork 4(are positioned on shift fork on the gear box casing 20 shift fork holes 14 earlier) be placed on and be positioned on five in the housing then; 5, big retarding gear 1 is installed on five, a side of big retarding gear is shaped on tooth 19; 6, left side bearing 2, installation shaft two paper washer 8 and gland 9 again are installed; 7, preceding loam cake 18, fixed installation rocking arm 16 and pin 17 are installed; 8, gland screw and packing ring 13,12 are installed, are put and swing to rocking arm 11, screw 10 is installed; 9, rocking arm 11 and clutch arm 16 are swung in connection, retaining screw 10 and 15 fixing can finishing.

Advantage one of the present utility model is to overcome the bump that causes in gearshift procedure, the working life of wearing and tearing, crack a joke, prolong vehicle; The 2nd, can overcome because gear wear is caused out of supply automatically, avoid the driving that causes in the descending process and the accident of falling the slide in the upward slope process; The 3rd, can overcome the gear shift caused accident of falling the slide not in place in the upward slope process; The 4th, gear shift freely.Just in case driving occurs, fall to slip also rapidly that engage a gear puts in place, thereby can increase the safety coefficient of vehicle and manpower and the Safety performance of locomotive; The 5th, simple, safety, reliable, existing vehicle need only be changed five axle construction, gear box casing and preceding on cover each and make a call to an aperture, other adds several add-on parts can transform success.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an a kind of embodiment's of the present utility model structural representation.

1 and 2 pair of the utility model is done with narration in conjunction with the accompanying drawings.

Tractor with small four wheels separated type security personnel clutch, it comprises housing (20) and preceding loam cake (18), big retarding gear (1) is positioned at the left part of five (7), bearing (2) is positioned on the two axial ends of five (7), the right part of five (7) is shaped on gear (6), big retarding gear (1) sky is enclosed within on five (7), the one side is provided with three circular teeth (19) that spacing equates around axle, clutch gear (3) be enclosed within five (7) go up and can move axially with big retarding gear (1) from or mesh, clutch spring (5) is enclosed within on five (7) between clutch gear (3) and gear (6), and shift fork (4) is positioned at the fork slot of clutch gear (3).Five (7) are made up of circular shaft (21), spline (22), gear three parts.Be shaped on shift fork hole (14) on housing (20) and the preceding loam cake (18).

The working principle of total is: work as let slip the clutch, pull bar (4) pulling shift fork (4) is done rotation counterclockwise, overcome spring (5) tension force, thread off with left side gear, realize big retarding gear (1) and five (7) power out of touch, like this, front clutch separates simultaneously with the back separator, make diesel engine and gearbox, gearbox and driving wheel separate simultaneously that gearbox stops operating or the inner teeth crop rotation with the speed rotation, in the middle of relative gear, the gear walking gear can arbitrarily go out into shelves, chooses gear, the reduction clutch pedal, back separator shift fork reduces prior to front clutch, and the following clutch gear of the tension force effect of spring (5) (3) is pushed big retarding gear (1) on the right, forces the engagement of three teeth, diesel engine forms one to driving wheel like this, work done simultaneously.
