Wheelbase control device and wheelbase control method based on torsion beam suspension

Abstract

The invention provides a wheelbase control device and a wheelbase control method based on a torsion beam suspension, and belongs to the technical field of automobile chassis systems. The wheelbase control device comprises an adjusting device, a torsion beam support, a driving assembly and an electronic control assembly. The adjusting device comprises a connecting support and a transmission device, and the connecting support is used for being fixedly connected with the vehicle body of the vehicle. The torsion beam support is used for being fixedly connected with the other end of the longitudinal beam and connected with the connecting support through the transmission device. The driving assembly is arranged on the connecting support and can drive the torsion beam support to move in the length direction of the vehicle. The electronic control assembly comprises a sensor and an electronic control unit, the sensor is used for detecting the ground clearance of the longitudinal beam, and the electronic control unit can control the driving assembly to drive the torsion beam support to move in the length direction of the vehicle according to the ground clearance of the longitudinal beam. The wheelbase control device can dynamically adjust and control the wheelbase of the vehicle, and the driving comfort and safety of the vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of automobile chassis systems, in particular to a wheelbase control device and a wheelbase control method based on a torsion beam suspension. Background technique [0002] The torsion beam suspension is the most commonly used rear suspension structure for entry-level domestic cars and joint venture vehicles. There are two main advantages of this type of suspension: first, the manufacturing cost is very low, and second, the torsion beam suspension has a relatively strong load-carrying capacity. , through a hard beam with a certain torque capacity as the load, it can ensure the bearing capacity and structural stability under the dynamic state of the vehicle. The front point of the longitudinal beam of the rear torsion beam suspension is usually fixedly connected with the vehicle body. When the vehicle's motion attitude changes, the beam body itself moves in an arc due to its structural characteristics, which w...

Problems solved by technology

[0004] The wheelbase adjustment method in the related art requires the driver to go to the 4S shop and other maintenance institutions regularly, and it cannot be adjusted in time when the vehicle is running normally.

If the wheelbase of the vehicle changes to a certain extent when the driver is driving normally, it will affect the performance of the vehicle and reduce the driving comfort and safety of the vehicle.
