Technical Field

The invention belongs to the technical field of steel plate spring shock absorption, and particularly relates to a special steel plate spring for an agricultural vehicle.

Background

The Leaf Spring (Leaf Spring) is an elastic element which is most widely applied in automobile suspensions, and is an elastic beam with approximately equal strength which is formed by combining a plurality of alloy Spring pieces with equal width but unequal length (the thickness can be equal or unequal). On the agricultural vehicle that needs to overcome complicated road conditions, leaf spring is the essential part. However, the agricultural vehicle is complex in use environment and dusty, dust is easily clamped by the leaf spring, friction between the leaf springs is increased, and abnormal noise is large.

In view of this, the applicant designs a special leaf spring of agricultural vehicle, can solve dust inclusion and abnormal sound problem, makes it more durable noise-resistant, is applicable to in the service environment of complicated many dusts more effectively increase of service life.

Disclosure of Invention

The invention aims to solve the technical problem of providing a special leaf spring for an agricultural vehicle, which can solve the problems of dust inclusion and abnormal sound, is firmer and noise-resistant, is more suitable for a complex and dusty use environment, and effectively prolongs the service life.

In order to solve the technical problems, the technical scheme of the invention is as follows: special leaf spring of agricultural vehicle, its characterized in that: the reed structure comprises more than five reeds, wherein each reed is arranged in the middle, and the lengths of the reeds arranged from top to bottom are gradually shortened; arranging a noise reduction interlayer between each reed, wherein the noise reduction interlayer is a polyurethane spacer; more than three binding clips are respectively arranged on two sides of the reed; the middle part of the reed is provided with a central through hole, and a fixing bolt mechanism is arranged in the central through hole in a penetrating way.

Preferably, the polyurethane spacer is a strip-shaped sheet body, and the cross section of the polyurethane spacer is in an I shape.

Preferably, the thinnest part of the polyurethane spacer is 1/3 of the thickest part.

Preferably, the length of the polyurethane spacer between two adjacent leaves is greater than the leaf of the shortest length and less than the leaf of the longest length.

Preferably, wear-resistant pits are arranged on two surfaces of the polyurethane spacer, and the height of the protrusions of the wear-resistant pits is not less than 3 mm.

Preferably, the coverage area of the wear-resistant pockmarks is not less than 75% of the single-sided surface area of the polyurethane spacer.

Compared with the prior art, the invention has the beneficial effects that:

the invention can solve the problems of dust inclusion and abnormal sound, is firmer and noise resistant, is more suitable for complex and dusty use environments, and effectively prolongs the service life.

Detailed Description

The special steel plate spring for the agricultural vehicle comprises more than five reeds, wherein each reed is arranged in the middle, and the lengths of the reeds arranged from top to bottom are gradually shortened; arranging a noise reduction interlayer between each reed, wherein the noise reduction interlayer is a polyurethane spacer; more than three binding clips are respectively arranged on two sides of the reed; the middle part of the reed is provided with a central through hole, and a fixing bolt mechanism is arranged in the central through hole in a penetrating way.

The polyurethane spacer is a strip-shaped sheet body, and the cross section of the polyurethane spacer is I-shaped.

The thinnest part of the polyurethane spacer is 1/3 of the thickest part.

The length of the polyurethane spacer between two adjacent reeds is larger than the shortest length of the reed and smaller than the longest length of the reed.

Wear-resisting pits are arranged on two sides of the polyurethane spacer, and the height of the protrusions of the wear-resisting pits is not less than 3 mm.

The coverage area of the wear-resistant pockmarks is not less than 75% of the surface area of the single surface of the polyurethane spacer.

The invention can solve the problems of dust inclusion and abnormal sound, is firmer and noise resistant, is more suitable for complex and dusty use environments, and effectively prolongs the service life.
