Heavy-Duty Vehicle Axle

Technical Field

The utility model relates to the technical field of automobile axles, and in particular to a heavy-duty vehicle axle.

Background Technology

An automobile axle is a very important structural component in the automobile chassis system. It serves as an intermediate device connecting the suspension structural components and the vehicle body, bearing forces from the ground, the entire vehicle, and the engine. At the same time, it supports the steering system and suspension system, and is used to isolate road vibration and noise transmission, thereby improving vehicle ride comfort and stability.

Existing heavy-duty vehicle axles lack:

a protective and anti-collision structure for the connecting rod and axle;

a cleaning mechanism for cleaning and washing the axle; and

a protective mechanism for safeguarding the axle.

Therefore, it is necessary to provide a heavy-duty vehicle axle capable of solving the above technical problems.

Utility Model Content

The utility model provides a heavy-duty vehicle axle, solving the problems that existing heavy-duty vehicle axles do not have:

a protective and anti-collision structure for the connecting rod axle;

a cleaning structure for cleaning the axle; and

a protection mechanism for the axle.

To solve the above technical problems, the utility model provides a heavy-duty vehicle axle comprising:

an axle;

a connecting rod fixedly connected inside the axle;

a shock absorption mechanism fixedly mounted at the bottom end of the connecting rod;

a cleaning mechanism sleeved outside the connecting rod; and

tires fixedly mounted on one side of the connecting rod.

Preferred Technical Solutions

1. Cleaning Mechanism Arrangement

The central axis of the cleaning mechanism coincides with the central axis of the tire, and the tires are symmetrically arranged about the central axis of the axle.

2. Shock Absorption Mechanism

The shock absorption mechanism includes:

a first telescopic rod;

a first spring fixedly mounted inside the first telescopic rod;

a first abutting block fixedly connected to the bottom end of the first spring;

a second telescopic rod fixedly mounted outside the first abutting block;

a second spring fixedly connected inside the second telescopic rod; and

a baffle fixedly connected to the bottom end of the second spring.

3. Elastic Structure

The first abutting block forms an elastic structure with the connecting rod through the first telescopic rod and the first spring.

The baffle forms an elastic structure with the connecting rod through the second spring and the second telescopic rod.

4. Cleaning Mechanism Structure

The cleaning mechanism includes:

a circular ring;

an inner cavity formed inside the circular ring;

a third spring fixedly connected inside the inner cavity;

a second abutting block fixedly mounted at the bottom end of the third spring;

a sliding groove formed inside the circular ring;

a sliding block movably connected inside the sliding groove;

a brush fixedly mounted at the bottom end of the second abutting block;

a spray nozzle fixedly connected to one side of the brush; and

an electric telescopic rod fixedly mounted on the outer wall of the circular ring.

5. Sliding Structure

The brush forms a sliding structure with the circular ring through the second abutting block, sliding block, and sliding groove.

The second abutting block forms an elastic structure with the circular ring through the third spring.

Beneficial Effects

Compared with related technologies, the heavy-duty vehicle axle provided by the utility model has the following beneficial effects:

1. Axle Cleaning and Protection

When the vehicle is running and powered on:

the electric telescopic rod at the bottom of the axle is energized;

the telescopic rod pushes the circular ring to clean the axle;

when the underside of the vehicle collides with a hard object, the baffle contacts the object;

the baffle provides shock absorption and protection for the axle, improving durability and ensuring normal vehicle operation.

2. Dual-Stage Shock Absorption

Under the action of the shock absorption mechanism:

when the baffle receives an impact, it drives the second telescopic rod inward;

the second spring reduces the impact between the baffle and the connecting rod;

when the protruding portion of the baffle contacts the first abutting block, the first abutting block moves inward through the first telescopic rod;

the first spring further reduces the impact force, thereby achieving an anti-collision effect and protecting the axle.

3. Cleaning and Cooling Function

Under the action of the cleaning mechanism:

when the vehicle starts, the electric telescopic rod pushes the circular ring;

the brush and spray nozzle inside the circular ring clean and cool the connecting rod;

the axle is thereby maintained and protected;

the brush is pressed tightly against the connecting rod through the elastic force of the third spring, allowing more thorough cleaning.

Working Principle

During operation:

the vehicle powers on the electric telescopic rod;

the electric telescopic rod pushes the circular ring;

the brush and spray nozzle inside the circular ring clean and cool the connecting rod;

the third spring presses the brush tightly against the connecting rod for better cleaning performance.

When the baffle receives an impact:

it drives the second telescopic rod inward;

the second spring absorbs part of the impact force;

when the protruding portion of the baffle contacts the first abutting block, the first spring further absorbs the impact force;

thereby achieving anti-collision protection for the axle.
