Anti-rollover cushioning frame

Abstract

The invention discloses an anti-rollover cushioning frame comprising a cushioning unit and an anti-rollover unit, the cushioning unit is used for relieving upward vibration in the vertical direction and improving the driving comfort, and the anti-rollover unit is used for improving the circumferential mass distribution of a vehicle body, reducing impact energy and reducing the possibility of rollover. The cushioning unit comprises an upper frame, a lower frame, a first cushioning piece and a second cushioning piece, and the anti-rollover unit comprises a driving piece and a buffering piece. According to the device, through the arrangement of the first cushioning piece and the second cushioning piece, the frame can have a two-stage damping function, vibration energy transmitted to a cab by the frame is effectively reduced, and the vibration level of a whole vehicle body is improved; and through the arrangement of the anti-rollover unit, the impact energy is reduced, and the possibility of rollover is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle frames, in particular to an anti-rollover cushioning vehicle frame. Background technique [0002] With the improvement of road conditions and the continuous development of the logistics industry, heavy-duty commercial vehicles are becoming more and more popular. Vehicle vibration during long-term driving will damage the physical and mental health of drivers. Different degrees of dizziness and fatigue are produced, which seriously affect the driving safety and comfort. Therefore, effectively reducing the vibration transmission on the car body has important research value for improving the vibration damping performance of the car body. However, most of the existing literature research and technical implementation are aimed at the improvement of the damping parts on the vehicle body, and there is little improvement analysis on the vibration transmission attenuation process of the frame.

However, most of the existing literature research and technical implementation are aimed at the improvement of the damping parts on the vehicle body, and there is little improvement analysis on the vibration transmission attenuation process of the frame

[0003]In addition, with the complexity of the cargo and the instability of the transportation, the vibration energy of the cargo will be continuously transmitted to the frame during the transportation, and some cargo transportation will generate The resonance effect produced when the vibration frequency overlaps with the natural frequency of the frame can easily further aggravate the transmitted vibration level of the frame, which in turn affects the comfort, safety and stability of the vehicle, and the traditional frame size frame and weight It is relatively large, and the weight distribution between left and right and front and rear is relatively balanced. However, in the environment of complete vehicle assembly, considering the randomness of the weight distribution of the driver, on-board equipment and cargo in the cab, it is easy to cause the vehicle body to move in the front and rear or left and right directions. Uneven upper weight, this kind of defect is likely to make the whole vehicle rollover under the condition of sharp turn and emergency stop
