Abstract
A micro tractor damping device is provided. A suspension is fixedly connected below a gear box and is installed with chains and chainwheels; a gear on the same axis with an upper chainwheel is meshed with a last level of gear of the gear box; one end of a rocker arm is articulated with the lower end of the suspension and the other end is articulated with an axis of a front wheel; the rocker arm is mounted with three transition gears meshed in turns; the transition gear on the right end of the rocker arm is on the same axis with a lower chainwheel; the axis acts as the cardan axle of the rocker arm and the suspension. The transition gear on the left end of the rocker arm is on the same axis with the front wheel; a shock absorber is fixedly connected between a base and the rocker arm; the force of the gear box is transferred to the transition gear on the rocker arm through the chains and chainwheels on the suspension to drive the front wheel. The transmission gear train can replace the chains and chainwheels. When the front wheel bumps or a diesel shakes, the rocker arm swinging up and down and the shock absorber can greatly lighten the shake of the machine body; the operator can control comfortably and the shake abrasion of each part of the tractor can be reduced; the service life is added. The device can conveniently perform modification and addition on the current micro tractors with simple structure and easy production.
Description
(1) technical field
The utility model relates to a kind of mini tractor shock absorption device, particularly a kind of before driving mini tractor shock absorption device.
(2) technical background
Existing shock absorption device is mounted on the front-wheel that turns to, and the mini tractor of before driving generally is difficult to install shock absorption device, so the vibrations of trac. fuselage were strong when diesel engine started, not only operator's discomfort also causes machine members to reduce service life easily.
(3) summary of the invention
The purpose of this utility model is the shock absorption device of a kind of mini tractor front-wheel that can be installed in before driving simple in structure of design.
The shock absorption device of the utility model design mini tractor front-wheel comprises change speed gear box, driving system, front-wheel.Affixed suspension under the change speed gear box is installed driving system on the suspension, rocking arm one end and the hinge joint of suspension lower end, the other end and front wheel spindle hinge joint.Transition gear is installed on the rocking arm, and the transition gear of front end is connected with the driving system of suspension, and the transition gear of rear end is coaxial with front-wheel.Bumper is fixed between support and the rocking arm.The power of driving engine passes to transition gear on the rocking arm by the driving system on change speed gear box afterbody gear, the suspension, thereby drives front-wheel.Rocking arm that swings up and down and bumper can alleviate the fuselage vibrations greatly.
The utility model has the advantages that: 1 has alleviated the vibrations of before driving mini tractor fuselage greatly, and the operator can be comfortable controls operation, has also significantly reduced the vibrations abrasion of each parts of trac., increases service life; 2 can change on existing mini tractor easily and install additional, are easy to apply; 3 is simple in structure, is easy to produce.
(4) description of drawings
Fig. 1 is the utility model mini tractor shock absorption device embodiment 1, wherein the transmission adopted sprocket wheel chain on the suspension;
Fig. 2 is the utility model mini tractor shock absorption device embodiment 2, the wherein multistage transmission gear of the transmission adopted on the suspension.
(5) specific embodiment
The utility model mini tractor shock absorption device embodiment 1 as shown in Figure 1,1 time affixed suspension 6 of change speed gear box is installed driving system sprocket wheel 3,7 and chain 4 on the suspension 6, last lower sprocket 3,7 is installed in suspension 6 upper and lower sides respectively, by chain 4 connections.Be meshed with change speed gear box 1 afterbody gear with upper sprocket wheel 3 coaxial gears 2.Rocking arm 9 one ends and the hinge joint of suspension 6 lower ends, the axle hinge joint of the other end and front-wheel 12.Three ingear transition gear A8, transition gear B10, transition gear C11 successively are installed on the rocking arm 9.The transition gear A8 and the lower sprocket 7 of rocking arm 9 right-hand members are coaxial, and this is the axle of rocking arm 9 and suspension 6 hinge joints simultaneously.The transition gear C11 of rocking arm 9 left ends is coaxial with front-wheel 12.Bumper 13 is fixed between support 14 and the rocking arm 9.The power of driving engine passes to transition gear 8,10,11 on the rocking arm 9 by sprocket wheel 3,7 on change speed gear box 1 afterbody gear, the suspension 6 and chain 4, thereby drives front-wheel 12.When the Uneven road front-wheel jolts, or diesel engine when vibrations operation, rocking arm 9 that swings up and down and bumper 13 alleviate the fuselage vibrations greatly.
Tension wheel 5, the degree of tension of scalable chain 4 are installed on the suspension 6.Available synchronous belt replaces chain 4.
The utility model mini tractor shock absorption device embodiment 2 as shown in Figure 2, the transition gear on its suspension 6, rocking arm 9, the rocking arm 9 and the structure of bumper 13 are identical with embodiment 1 with installation.Installing successively on the affixed suspension 6 of the change speed gear box 1 of embodiment 2,3～7 transmission gears 15 of ingear and the coaxial gear 2 of transmission gear 15-1 topmost are meshed with change speed gear box 1 afterbody gear.Transmission gear 15-2 bottom is coaxial with the transition gear A8 of rocking arm 9 right-hand members, and this is the axle of rocking arm 9 and suspension 6 hinge joints simultaneously.The power of driving engine passes to transition gear 8,10,11 on the rocking arm 9 by gear 2, transmission gear 15 on change speed gear box 1 afterbody gear, the suspension 6, thereby drives front-wheel 12.
