Abstract
The utility model relates to a normal shock absorber of a bulldozer. The normal shock absorber comprises a left clamping plate fixedly connected to a transitional disk, a right clamping plate connected to the left clamping plate from a fixed distance, a wheel hub arranged between the left clamping plate and the right clamping plate, and cylindrical spiral compression springs arranged between the left clamping plate and the circumference of the wheel hub as well as between the right clamping plate and the circumference of the wheel hub, wherein the springs are placed in fan-shaped spring cavities formed by the left clamping plate, the right clamping plate and the wheel hub. Through the arrangement, a tangential acting force of output torque of an engine or a tangential inertial force of a torque converter in braking can be acted on the end surfaces of the springs along the normal directions of the end surfaces of the springs, so that the overall external force resistance of the springs is brought into full play, and the technical defect of unilateral stress of existing springs of the shock absorber is changed. The normal shock absorber has the advantages of reasonable design, strong external force resistance, good shock absorption effect and long service life.
Description
Technical field
The utility model relates to engineering machinery design and manufacturing technology field, is specially the normal direction shock-damping structure of the damper that uses on a kind of bulldozer, particularly this damper.
Background technology
The damper that uses on the bulldozer is arranged between motor and the torque-converters, because bulldozer has heavier vehicle body, therefore when accelerating or brake, bulldozer can produce greatly circumferential shock loading of moment, vehicle body inertia will react on motor by torque-converters, owing to be provided with damper therebetween, therefore, the reaction force of motor just can concentrate on damper, has been reduced collision and vibrations between each component by the inertia force of the absorption of the spring in damper vehicle body.Existing bulldozer damper, be provided with many uniform cylindrical helical compression springs at the junction plate that is fixed in engine flywheel being connected of torque-converters wheel hub between the circumference with being fixed in, two end faces of every spring all are symmetricly set on the both sides of wheel hub axial centre section.There is technical deficiency in arranging like this because the optimum orientation that cylindrical helical compression spring is resisted external force for along spring axially, that is: the both ends of the surface of spring are vertical with external force.And there are certain angle in the both ends of the surface of existing damper medi-spring and force direction, at first monolateral stressed during the spring shock-absorbing, then reaction force is large on one side to be positioned at the near spring in wheel hub center, one side reaction force far away is little, not only directly cause damping capaicty to weaken, and produce easily the tired flexural deformation of spring, so spring is in abnormal operating state all the time.
Summary of the invention
The purpose of this utility model is to provide a kind of bulldozer normal direction damper, by the spring state rationally is set, realizes the best shock-absorbing effect of damper.
To achieve these goals, the utility model Bian gets following technical scheme and implements: a kind of bulldozer normal direction damper, comprise transition disc, be fixed in the left clamping plate on the transition disc, spacing is connected in the right clamping plate on the left clamping plate, be arranged on a left side, wheel hub between the right clamping plate and place a left side, cylindrical helical compression spring between right clamping plate and wheel hub are circumferential, spring is placed on by a left side, in the spring cavity that the window that right clamping plate and wheel hub are offered respectively on same diameter forms, it is characterized in that a described left side, the window of offering respectively on right clamping plate and the wheel hub is fan-shaped, and fan-shaped both ends of the surface are with left, the axial centre cross section of right clamping plate and wheel hub overlaps, and consists of thus fan-shaped spring cavity; Described spring bending is placed in the fan-shaped spring cavity.
The technical program can make engine output torque tangential forces or when braking torque-converters tangential inertial force act on the end face of spring along the normal orientation of spring end face, the ability that makes spring integral body resist external force is not fully exerted, and has changed the existing monolateral stressed technical deficiency of spring of damper.
The utlity model has reasonable in design, resist that external force is strong, the advantage of good damping effect, long service life.
Description of drawings
Accompanying drawing 1 is main TV structure schematic diagram of the present utility model;
Accompanying drawing 2 is left sectional structure schematic diagram of the present utility model.
In accompanying drawing 1,2: 1 transition disc, 2 left clamping plate, 3 wheel hubs, 4 right clamping plate, 5 cylindrical helical compression springs, 201,301,401 fan-shaped windows.
The specific embodiment
As shown in Figure 1, the utility model comprises transition disc 1, left clamping plate 2, wheel hub 3, right clamping plate 4, cylindrical helical compression spring 5, and left clamping plate 2 are fixedly connected on the transition disc 1; Right clamping plate 4 are fixedly connected on the left clamping plate 1 by riveted pin spacing; Wheel hub 3 places between left clamping plate 2 and the right clamping plate 4; Have separately fan-shaped window 201,301 and 401 on the same setting circumference of left clamping plate 2, wheel hub 3, right clamping plate 4, and jointly form fan-shaped spring cavity by fan-shaped window 201,301 and 401; Cylindrical helical compression spring 5 bendings are placed in the fan-shaped spring cavity, and both ends of the surface overlap with the axial centre cross section that left clamping plate 2, wheel hub 3, right clamping plate 4 have.
In actual the use, transition disc 1 is connected with engine flywheel, wheel hub 3 is connected with torque-converters by shaft coupling, the tangential inertial force of torque-converters when the tangential forces of engine output torque or braking, act directly on along the normal orientation of spring end face form on the end face of the cylindrical helical compression spring 5 after the bending whole stressed, and the direction of active force is opposite with the spring reaction force direction, and equate after compression, changed the monolateral stressed technical deficiency of original damper medi-spring, improved spring integral body and resisted the ability of external force, made the damping effect of damper reach best.
