A linear motor type energy-feeding suspension for heavy-duty vehicles

Abstract

The invention discloses a linear motor type energy-feedback suspension bracket for heavy-duty vehicles. An upper lifting lug is fixed on a motor fixing plate, and the motor fixing plate is positioned at the upper end of an upper support and is fixed on the casing of a linear motor along with the upper support; the linear motor is connected with a main piston through the primary of the linear motor, so that the force of the linear motor is transmitted to a hydraulic amplifying device; the hydraulic amplifying device comprises a main oil chamber, the main piston, a plurality of accessory oil chambers, a plurality of accessory pistons, and a plurality of accessory piston rods, wherein the accessory oil chambers are connected in parallel with the main oil chamber and uniformly surround the main oil chamber; the upper section of a spring is connected with the upper support, and the lower end of the spring is connected with a lower support positioned at the lower part of the hydraulic amplifying device. The linear motor type energy-feedback suspension bracket disclosed by the invention solves the problem that the output of the linear motor is small as power, the primary velocity of the movement of the linear motor is increased, and the power generating efficiency is improved; besides, the problem that because the linear motor is connected in series with the hydraulic amplifying device, the overall length is too long is solved, the structure is compact, and the linear motor type energy-feedback suspension bracket conforms to vehicle requirements.

Description

technical field [0001] The invention relates to vehicles, in particular to a linear motor type energy-feeding suspension for heavy vehicles. Background technique [0002] With the deterioration of the environment and the increasingly prominent problem of energy shortage, energy conservation and emission reduction have become the theme of the development of the automobile industry, and corresponding energy-saving measures have been widely used. The use of linear motors as actuators has attracted the attention of many scholars, but the current linear motors in energy-fed suspensions have the problems of small power and low power generation efficiency, and high-performance linear motors are expensive. If high-performance linear motors are used Performance linear motors lead to prohibitively high vehicle suspension costs. [0003] The vehicle energy-feeding suspension needs to convert the vibration energy into electric energy through the electric motor to realize energy recover...

Problems solved by technology

[0004] Heavy-duty vehicles have the characteristics of large mass and high load, so the linear motor type energy-feed suspension of heavy-duty vehicles is required to have the characteristics of providing greater power. However, if the solution is only from the internal structure of the linear motor, the cost required is too high. big and difficult
