Double Suspension Arm Structure for Heavy-Duty Vehicles

Technical Field

The utility model relates to the field of automotive technology, in particular to a double suspension arm structure for heavy-duty vehicles.

Background Technology

During vehicle operation, bumps and vibrations are inevitable. These vibrations negatively affect drivers and passengers and may also damage vehicle systems. Therefore, improvements are needed to reduce vehicle body vibration and improve ride stability.

Existing double suspension arm structures for heavy-duty vehicles lack:

a mechanism capable of effectively reducing lateral vibration forces,

a mechanism for rapidly resetting the shock absorber,

and a structure enabling convenient installation and removal between the suspension arm and vehicle body.

Therefore, it is necessary to provide a double suspension arm structure for heavy-duty vehicles to solve the above technical problems.

Summary of the Utility Model

The utility model provides a double suspension arm structure for heavy-duty vehicles, which solves the problems that existing structures cannot effectively reduce lateral vibration force, cannot rapidly reset the shock absorber, and do not facilitate convenient connection and disassembly between the suspension arm and the vehicle body.

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

The double suspension arm structure comprises:

a first connecting rod,

a second connecting rod connected to the outer side of the first connecting rod,

a buffering mechanism arranged between the first connecting rod and the second connecting rod,

a connecting block fixed at the top end of the second connecting rod,

a movable shaft fixed to the outer side of the connecting block,

a shock absorber fixed at the top end of the movable shaft,

a first spring connected to the outer side of the shock absorber,

a reset mechanism arranged between the shock absorber and the first connecting rod,

a fixing mechanism connected to the outer side of the shock absorber,

a connecting ring fixed on the outer side of the first connecting rod.

The fixing mechanism includes:

a bolt,

a vehicle body threadedly connected with the bolt,

and a nut threadedly connected to the outer side of the bolt.

Preferred Embodiments

Fixing Structure

The vehicle body, bolt, nut, and connecting ring form a fixing structure, and the transverse axis of the bolt coincides with the transverse axis of the nut.

Buffering Mechanism

The buffering mechanism includes:

a third connecting rod,

a first sliding block fixed at the top end of the third connecting rod,

a first sliding groove slidably connected with the first sliding block,

and a third spring installed inside the first sliding groove.

The third connecting rod forms:

a sliding structure with the second connecting rod through the first sliding block and the first sliding groove,

and an elastic structure with the second connecting rod through the third spring.

Reset Mechanism

The reset mechanism includes:

a first connecting member,

a movable rod fixed to the outer side of the first connecting member,

a second connecting member fixed outside the movable rod,

a second sliding block fixed at the bottom end of the second connecting member,

a second sliding groove slidably connected with the second sliding block,

and a second spring installed inside the second sliding groove.

The movable rod:

forms a movable structure with the second sliding block through the second connecting member,

and forms a folding structure with the shock absorber through the first connecting member.

Beneficial Effects

Compared with related technologies, the utility model has the following advantages:

1. Reduction of Lateral Vibration

When the vehicle experiences vertical bumps during driving, lateral swaying also occurs. During lateral movement:

the first connecting rod moves through the third connecting rod,

causing the third spring to compress,

the compressed third spring generates a reaction force,

thereby pulling the third connecting rod back to its original position,

which in turn restores the first connecting rod.

As a result, lateral vibration of the vehicle is reduced, providing drivers and passengers with a more comfortable riding experience.

2. Faster Shock Absorber Reset Response

When the vehicle encounters road bumps:

the shock absorber and first spring operate together for damping and resetting,

enabling rapid response between the vehicle body and wheels,

thereby improving vehicle stability.

The reset mechanism further accelerates the response speed:

when the shock absorber operates, the movable rod rotates,

driving the second sliding block to move within the second sliding groove,

compressing the second spring,

the second spring then elastically resets,

pushing the movable rod back to its original position,

thereby enabling faster shock absorber recovery.

This improves the responsiveness between the vehicle body and wheels.

3. Convenient Installation and Disassembly

Through the fixing mechanism:

the bolt passes through the threaded groove of the connecting ring and engages with the threaded groove of the vehicle body,

thereby connecting the double suspension arm structure with the vehicle body.

This structure:

enables quicker and more convenient installation between the wheel assembly and the vehicle body,

and also facilitates easy removal and replacement of the suspension arm structure.

Working Principle

During vehicle operation:

vertical road bumps generate both vertical vibration and lateral sway,

the first connecting rod moves through the third connecting rod,

compressing the third spring,

the third spring then restores elastically and pulls the third connecting rod back,

thereby restoring the first connecting rod and reducing lateral sway.

Meanwhile:

the shock absorber and first spring perform damping and reset functions,

the reset mechanism further accelerates shock absorber recovery,

the movable rod rotates during shock absorber operation,

driving the second sliding block within the second sliding groove,

compressing the second spring,

the second spring then elastically restores and pushes the movable rod back,

thereby improving suspension response speed and vehicle stability.

For installation:

the bolt passes through the threaded groove in the connecting ring and engages with the threaded groove of the vehicle body,

thereby fixing the double suspension arm structure to the vehicle body,

enabling convenient installation, removal, and replacement.
