Abstract

The present invention relates to a vehicle leaf spring (3). According to the present invention, a vehicle leaf spring chain net (4) of a hoop net type is connected to the bottom of a vehicle and wraps up to the maximum height (2) of a leaf spring, thereby preventing debris left from the leaf spring (3) from being separated toward the outside and being scattered. Accordingly, according to the present invention, a risk factor can be reduced by removing debris of the leaf spring (3) projecting while driving a vehicle to prevent secondary damage.

Description

Vehicle leaf spring chain net {For vehicles Leaf spring Chain net}

Accordingly, the present invention relates to a vehicle leaf spring, and more particularly, the rear wheel shaft is connected to the steel frame on the leaf spring, and the rear wheel shaft is connected to the lower middle point of the leaf spring, so that the leaf spring reduces vibration and shock, regardless of unevenness on the road. It is a technology that safely operates, improves the ride comfort, and protects the body and the engine.

BACKGROUND ART In general, automobiles are machines that drive on roads, in mountains, and the like, using a prime mover mounted on a vehicle body as a power source, and carry people or cargo or perform various tasks. Suspension (suspension), which is one of the important devices in the car, connects between the body and the axle, absorbs shocks and vibrations from the road surface, improves the ride quality, protects the body and the engine, and springs and shock absorbers. ), And stabilizer components. Springs include metals such as leaf springs, coil springs and torsion bars, and rubber springs and air springs. Leaf spring refers to a spring device made by stacking steel plates of different lengths. These leaf springs have a merit of suppressing the vibrations, and thus have a merit for mitigating impact, and are used in trucks and large buses. In addition, by changing the number of steel sheet in various ways or by changing the curvature, which is the rate of change in the curve direction, it is possible to change the spring efficiency and weight capacity. Therefore, when broken, the fragments fly strongly, causing secondary damage, and driving force or ride comfort is significantly reduced. Therefore, the circular steel, which is a metal material, is processed into a ring shape with a certain length, and the joint is welded or welded. The heat and corrosion resistance is excellent and the shape is maintained. Try to use.

Existing leaf springs cause secondary damage due to excessive fragmentation due to fatigue accumulation or corrosion caused by overload. Therefore, it is determined that the effects of the secondary damage can be seen using the invention.

This technology devises the strength and corrosion that the chain springs withstand the force of the leaf spring shocked by the accumulation of fatigue in the leaf spring, and calculates and prevents the smallest size of the leaf spring to be blown out. This eliminates the secondary damage caused by the leaf spring by adjusting the chain hole size so that the state of the leaf spring can be identified.

As described above, according to the present invention, it is judged that the effect of the secondary damage can be seen with the vehicle leaf spring chain, and the impact absorption of the leaf spring can be used as it is by increasing the safety level and wrapping up to the maximum maximum height of the leaf spring. .

The representative figure is the completeness with which this invention was attached.
2 is a view showing a chain attached to the present invention.

1 is a general vehicle leaf spring, which is connected between the steel frame (1) and the leaf spring (3) by a spring eye (6), and the reinforcement (7) at both ends and the middle of the leaf spring to hold the leaf spring . Then, the rear wheel shaft of the vehicle is connected to the middle lower end of the leaf spring. Figure 2-2 is a chain network (4) constituting the chain in the form of a net, it should be able to insert a tool or hand by connecting the chain of chain type (5) that can be opened and closed at a specific interval. FIG. 2-1 is a type of wrapping the vehicle leaf spring 3 of FIG. 1 with the chain network 4 of FIG. 2-2 from the steel frame 1 mounted on the leaf spring of FIG. 1 to the maximum height 2 of the leaf spring. to be.

Claims (1)

A device that connects with a vehicle to prevent the debris from falling off the leaf spring by wrapping it in a mesh-type chain from the steel frame on the leaf spring to absorb shocks and vibrations to the maximum height of the leaf spring.
