Technical field

The present invention relates to engineering machinery fields, and in particular to binodal creeper truck carries vibration damping leaf spring.

Background technique

Binodal endless-track vehicle and single-unit endless-track vehicle domestic at present is all using car body as carrying, the vibration damping of vehicle according to The behavioral system plug-in by car body.Vehicle layout is limited to behavioral system and interior space, causes Bus inner layout components space Compact maintenance is difficult；Running gear crawler belt and structure are limited in width direction, so that contact area is small, pressure is high, vehicle Passability is poor.

Summary of the invention

The present invention provides a kind of binodal creeper truck support damping element, and the present invention is to solve above-mentioned the deficiencies in the prior art, And provide it is a kind of by " carrying vibration damping leaf spring " device, increase vehicle body space, cancel car body bearing function, reduce car body manufacture at This, expands convenient for vehicle layout and behavioral system, improves trafficability.

To solve the above problems, damping element is whole the present invention adopts the following technical scheme: creeper truck supports damping element It is a spring slab organization, is car body contact surface 1 among damping element, damping element both ends is walking contact surface 2, and car body connects By 3 transition of inclined-plane between contacting surface 1 and walking contact surface 2, the inclined-plane 3 and walking contact surface 2 of 1 two sides of car body contact surface are in symmetrical Structure.

The beneficial effect of the invention patent is: increasing vehicle body space, reduces car body manufacturing cost, is convenient for maintenance, just In vehicle layout, reduction behavioral system vibration-damping function and manufacturing cost, behavioral system expansion capability is improved, improves vehicle and pass through Property.The configuration of the present invention is simple simultaneously, installation, maintenance is convenient, long service life, and suitable environment range is wide.

Symbol description in figure: car body contact surface 1, contact surface 2 of walking, inclined-plane 3.

Specific embodiment

The present invention is described in detail with optimal embodiment below.

As shown in Figure 1-3, creeper truck supports damping element, damping element is integrally a spring slab organization, vibration damping member It is car body contact surface among part, damping element both ends are walking contact surfaces, by oblique between car body contact surface and walking contact surface Face transition, the inclined-plane and walking contact surface of car body contact surface two sides are in symmetrical structure.

It is in 140-165 degree angle between inclined-plane and car body contact surface.

The width of car body contact surface is 1.5-3 times of walking interface width.

Creeper truck carrying damping element shape is similar to U-shaped (see attached drawing 1).

Carrying vibration damping leaf spring material thickness composite construction steel use silicon-manganese spring steel for main material, addition nickel, chromium, vanadium, boron, Molybdenum chemical component, it is respectively 18%, 18%, 8%, 0.05%, 0.2% that quality, which is added, in nickel, chromium, vanadium, boron, molybdenum in silicon-manganese spring steel；Add High-intensitive, high tenacity and high-fatigue strength can be made it have by entering above-mentioned material.

More preferably to realize that the plate of above-mentioned 20mm thickness is heated up to 800 ° by its carrying and vibration-damping function, pass through large-sized forging machine Shape approximate U shape is forged, numerical control machining center shapes, 870 °C of ± 10 °C of heat preservations 4 of hardening heat on heat-treatment furnace later Hour, oil is cooling；3 hours are kept the temperature for 550 °C ± 50 ° of high tempering after quenching, and water, oil are cooling to produce qualified vibration damping leaf spring. The leaf spring is located at car body and behavioral system between the two, with its car body and behavioral system contact surface all there are threaded hole, three it Between fixed by high-strength bolt and self-locking nut.Fig. 1 show leaf spring and installs free state figure, when the vehicle is running, vehicle Contact level and action contact surface free state and it is parallel between swing.One section vehicle need two pieces carry vibration damping leaf spring, two Leaf spring position is determined by vehicle center of gravity.
