Semi-Trailer Disc Suspension Axle

Technical Field

The utility model relates to an axle, and particularly to a disc suspension axle, belonging to the technical field of vehicle axles.

Background Technology

According to different suspension structures, disc axles are divided into integral type and split type. When a non-independent suspension is adopted, the middle portion of the axle is a solid or hollow center beam, and such an axle is an integral axle. A split axle adopts an articulated structure and is used together with an independent suspension. Most commonly used disc suspension axles in daily life belong to this category.

During the use of existing disc suspension axles, the axle rod is easily affected by road obstacles and may fracture, thereby reducing the safety factor and greatly shortening the service life, resulting in certain limitations during use.

Utility Model Content

The purpose of the utility model is to provide a disc suspension axle to solve the problems mentioned in the background technology, namely that the axle rod is prone to fracture due to road obstacles during use, thereby reducing safety and greatly shortening service life.

To achieve the above purpose, the utility model provides the following technical solution:

A disc suspension axle comprises an axle rod. Brake mechanisms are arranged at both ends of the axle rod. Each brake mechanism includes a brake caliper and a brake disc. Brake discs are fixedly installed at both ends of the axle rod, and brake calipers are fixedly installed on both sides of the top end of the axle rod.

An arc-shaped buffer plate is arranged above the axle rod, and a buffering mechanism is arranged between the axle rod and the arc-shaped buffer plate.

The buffering mechanism includes:

a buffer block,

a first spring,

a pin shaft,

a second spring,

support blocks,

shaft rods,

shaft sleeves,

hinges,

swing rods,

and third springs.

A buffer block is fixedly installed at the middle portion of the top end of the axle rod. A pin shaft is slidably connected inside the buffer block. The top end of the pin shaft passes through the buffer block and is fixedly connected to the middle portion of the bottom end of the arc-shaped buffer plate.

A first spring is fixedly installed inside the buffer block, and one end of the first spring is fixedly connected to the bottom end of the pin shaft.

A second spring is movably sleeved outside the buffer block.

Two support blocks are fixedly installed on both sides of the top end of the axle rod. Every two support blocks form one group, and a shaft rod is fixedly installed between each group of support blocks.

Shaft sleeves are sleeved outside the two shaft rods, and one end of each shaft sleeve is hinged to a swing rod through a hinge.

Two third springs are movably sleeved outside each shaft rod.

Preferred Technical Solutions

One end of the second spring is fixedly connected to the middle portion of the top end of the axle rod, and the other end is fixedly connected to the middle portion of the bottom end of the arc-shaped buffer plate, thereby providing stable support.

Every two third springs form one group. One end of each third spring is fixedly connected to one side of the corresponding support block, while the other end is fixedly connected to both sides of the corresponding shaft sleeve, thereby providing limiting and buffering functions.

One end of each swing rod is hinged to both sides of the bottom end of the arc-shaped buffer plate through hinges, thereby providing supporting and limiting functions.

Multiple heat dissipation holes are evenly formed on the surfaces of the two brake discs to improve heat dissipation performance.

Mounting plates are fixedly installed on both sides of the top end of the arc-shaped buffer plate, and mounting holes are formed inside the mounting plates, facilitating installation and assembly.

Beneficial Effects

Compared with the prior art, the utility model has the following beneficial effects:

Through the mutual cooperation among the buffer block, first spring, second spring, pin shaft, and arc-shaped buffer plate, when the axle rod and arc-shaped buffer plate are subjected to load, the first spring and second spring compress and extend accordingly. Due to the elastic support provided by the springs themselves, the axle rod receives effective buffering protection, thereby preventing fracture and extending service life.

At the same time, through the mutual cooperation among the third springs, shaft sleeves, shaft rods, hinges, swing rods, and support blocks, when the axle rod and arc-shaped buffer plate are subjected to load, the corresponding swing rods swing accordingly. Due to the elastic support of the third springs, the springs compress and extend correspondingly, thus providing excellent buffering performance, improving safety, and making the structure more convenient to use.

Specific Embodiment

When the disc suspension axle is used, it is first assembled onto the vehicle through a lifting device and fixed by the mounting plates and mounting holes.

During operation, when the axle rod and arc-shaped buffer plate bear load, the first spring and second spring compress and extend, thereby buffering the axle rod and preventing fracture, thus extending its service life.

Meanwhile, with the cooperation of the hinges, the swing rods swing correspondingly, causing the shaft sleeves to slide along the shaft rods. Due to the elastic support of the third springs, the springs compress and extend correspondingly, thereby providing excellent buffering effects, improving safety, and making the structure more convenient to use.
