Description

Technical Field

[0001] This application relates to the field of thrust rods, and more particularly to an automotive shock-absorbing thrust rod. Background Technology

[0002] The automotive shock absorber thrust bar is a key component of the suspension system. Its core functions include: absorbing approximately 70%-80% of impact energy through a V-shaped structure or hydraulic device, effectively reducing axle lateral displacement by 30%-50%; in heavy vehicles, it can withstand 5-8 tons of traction / braking torque, improving the driving stability of non-independent suspension models by more than 40%. This device achieves buffering through springs or hydraulic damping, reducing chassis impact noise by 15-20 decibels. It is widely used in commercial vehicles, construction machinery, and other fields, and is an important safety component for ensuring vehicle dynamic balance. In conventional automotive shock absorber thrust bars, a sliding rod is slidably installed at one end of the fixed rod. The fixed rod and sliding rod are respectively installed between the frame and the axle, and the fixed rod and sliding rod buffer the vibrations generated during vehicle operation.

[0003] Regarding the aforementioned technologies, the inventors believe that traditional thrust rods are often used for cushioning when subjected to impact. However, since thrust rods are long straight structures, they are prone to excessive stress at a single point when subjected to impact, which can lead to deformation of the thrust rod or even fatigue fracture of the component.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem of excessive stress on a single point of conventional thrust rods leading to easy damage, this application provides an automotive buffer thrust rod.

[0006] The automotive buffer thrust rod provided in this application adopts the following technical solution:

[0007] A car buffer thrust rod includes a fixed rod and several adjusting rods. A slide rod is slidably connected to the top of the fixed rod, and the center of the slide rod is on the same straight line as the center of the fixed rod. A limit block is fixedly installed at one end of the adjusting rod. A slide cylinder is slidably installed on the surface of the limit block, and a support spring is fixedly connected to one end of the limit block. The end of the support spring away from the adjusting rod is fixedly installed to the inner wall of the slide cylinder, and the center of the support spring is on the same straight line as the center of the adjusting rod. One end of the adjusting rod is rotatably connected to the surface of the slide rod. Several adjusting rods are arranged in a circular array around the center of the fixed rod. The dimensions of the surface of the limit block are adapted to the dimensions of the inner wall of the slide cylinder.

[0008] Preferably, a connecting seat is rotatably mounted on the top of the slide cylinder, and a fixing frame is fixedly connected to the top of the connecting seat. The bottom end of the fixing frame is fixedly mounted to the top of the slide rod, and the center of the fixing frame and the center of the slide rod are on the same straight line.

[0009] Preferably, the inner wall of the fixing frame is fitted with a plurality of fixing bolts, and the plurality of fixing bolts are arranged in a circular array with the center of the fixing frame as the axis.

[0010] Preferably, one end of the adjusting rod is rotatably connected to a slider, and the surface of the fixed rod is provided with a plurality of connecting grooves adapted to the slider, and the inner wall of the connecting groove is slidably installed with the surface of the slider.

[0011] Preferably, a connecting ring is fixedly connected to the bottom end of several of the sliders, the inner wall of the connecting ring is slidably installed with the surface of the fixed rod, and the size of the inner wall of the connecting ring is adapted to the size of the surface of the fixed rod.

[0012] Preferably, a push spring is fixedly connected to the bottom end of the connecting ring, and the center of the push spring is on the same straight line as the center of the connecting ring.

This achieves efficient absorption and uniform dispersion of vibration force. A connecting seat is rotatably installed on the top of the sliding cylinder, and a fixing frame is fixedly connected to the top of the connecting seat. This allows for easy connection of several sliding cylinders using the fixing frame. Several fixing bolts are snapped into the inside of the fixing frame, allowing for installation and disassembly of the device using the fixing bolts.
