Abstract

The utility model provides a shockproof universal wheel. The shockproof universal wheel comprises a wheel installed at the front end of a rotary support through an axle, the rear end of the rotary support is supported at the bottom of a spring seat through a hinge pin, the top of the spring seat is connected onto a mounting base, a coil spring is arranged in the spring seat, one end of the coil spring is connected at the rear end of the spring seat, and the other end of the coil spring is connected at the rear end of the rotary support. A thrust ball bearing is mounted on the mounting base and connected with the top of the spring seat, and the wheel can rotate freely during shifting. According to the shockproof universal wheel, a damping mechanism with the spring is adopted, shock and impact load transmitted from the ground to working position apparatuses can be absorbed effectively, noise of the working position apparatuses during movement can be reduced greatly, and the shockproof universal wheel can be generally applied to parts among working positions or semi-finished product transporting working position apparatuses of trolley wheels in automobile or machine manufacturing industries.

Description

Shockproof cardan wheel

Technical field

The utility model relates to the wheel of transport vehicle, specifically the anti-vibration noise reducing of a kind of automobile and machinery industry logistics transportation dolly transportation cardan wheel.

Background technology

When logistics department joins required various parts from the warehouse to each assembly station distribution of manufacturing line with auto assembly, often adopt the storage battery car traction to fill the working position apparatus of various parts, and it is transported to corresponding station.Therefore, working position apparatus also must install wheel additional, and front-wheel is necessary for cardan wheel in order to turn flexibly.But because wheel used is common wheel at present, without shock-absorbing function, transport in process vibrations very large, noise is also very large, when especially passing through the road surface of uneven, shake more severely, noise is also just larger, often parts are shaken or the surface scuffing of colliding with, serious also can affect the parts in-use performance.

Summary of the invention

For the wheel vibrations that reduce working position apparatus and the noise that produces, the utility model provides a kind of shockproof cardan wheel.

The technical solution adopted in the utility model is: a kind of shockproof cardan wheel, comprise wheel, wheel is loaded on the swinging strut front end by axletree, the rear end of swinging strut is supported in bottom spring perch by bearing pin, the spring perch top is connected on mounting seat, coil spring is housed in spring perch, and coil spring one end is connected in the rear end of spring perch, and the other end is connected in the swinging strut rear end.

Coil spring can be caught wheel the impulsive force that comes and decompose to spring structure from ground, then compression and these impact loads of elongation absorption by spring play the effect of protection parts to reduce vibrations and noise.

Thrust ball bearing is housed on mounting seat, and the top of spring perch connects thrust ball bearing, and wheel is free to rotate when changing, and adopts this mechanism can improve the service life of device.

The shockproof cardan wheel that the utility model provides; compare with common wheel; employing is with the damping of spring; can effectively absorb the vibrations and the impact load that reach working position apparatus from ground; greatly reduce working position apparatus at the noise of motion process; effectively protected surface quality and the performance of parts, guaranteed parts from the warehouse to the integraty of manufacturing line station, laid the foundation for improving the final assembly quality of product.In addition, the universal steering structure that thrust ball bearing is housed can significantly improve its service life, has improved the durability of its use.Simple in structure, easily to make, total mass is little,

The utility model field of application is wider, can generally be used in parts or half-blank transhipment working position apparatus car wheel between automobile and each station of machine industry.

Description of drawings

Fig. 1 is the block diagram of the shockproof cardan wheel of the utility model.

Fig. 2 is the part sectional view of the shockproof cardan wheel of the utility model.

In figure, the 1-wheel, the 2-axletree, the 3-swinging strut, the 4-bearing pin, the 5-spring perch, the 6-mounting seat, the 7-coil spring, the 8-thrust ball bearing, 9-spring set pin,

The specific embodiment

Below in conjunction with accompanying drawing, the claimed technical scheme of the utility model is done and illustrated.

A kind of shockproof cardan wheel, as shown in Figure 1, comprise wheel 1, wheel 1 adopts polyurethane iron clad wheel, wheel 1 is loaded on swinging strut 3 front ends by axletree 2, the rear end of swinging strut 3 is supported in spring perch 5 bottoms by bearing pin 4, spring perch 5 tops are connected on mounting seat 6, coil spring 7 is housed in spring perch 5, coil spring 7 one ends are connected in the rear end of spring perch 5, the other end is connected in swinging strut 3 rear ends, and the spring perch rear end is fixed with spring set pin 9, and coil spring 7 is placed on spring set pin 9.

As shown in Figure 2, thrust ball bearing 8 is housed on mounting seat 6, the top of spring perch 5 connects thrust ball bearing 8, and thrust ball bearing 6 is bolted on mounting seat 6.

Wheel 1 is in motion process, constantly receive the impact load that transmits from ground, and by axletree 2, vibration is reached swinging strut 3, swinging strut 3 compression coil spring 7 actings, be converted into the elastic potential energy of coil spring 7, after impacting disappearance, coil spring 7 returns to former length, so constantly be repeated compression elongation again, coil spring 7 constantly absorbs these impacts and finally is translated into interior can consumption, the effect that damping consumes has been played in the vibration that comes up from the wheel transmission, and vibrating noise also disappears thereupon.
