Problems solved by technology

[0005] The technical problem to be solved by the present invention is to recover the vibration energy of the suspension by utilizing the relative motion between the sprung mass and the unsprung mass during the running of the vehicle, so as to improve the fuel economy of the vehicle and reduce energy consumption; And it is required that the damping force of the suspension can be changed according to the change of the driving conditions of the vehicle, so as to improve the ride comfort and handling stability of the vehicle.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with drawings and embodiments.

[0018] The new semi-active suspension energy feeder integrates the barrel permanent magnet linear generator into the traditional hybrid vehicle hydraulic shock absorber, and sets two radial throttling valves on the piston rod of the hydraulic shock absorber. The hole is obtained, including: an energy feeding mechanism 10 , an orifice adjusting mechanism 20 , a damping force control mechanism 30 , a hydraulic shock absorber main body 40 and an outer cover 50 .

[0019] The energy feeding mechanism 10 is a cylindrical permanent magnet linear generator, which is composed of a piston rod mover 101 and a stator 102 that can move relatively. The stator 102 is located on the outer peripheral side of the liquid storage cylinder 402, including three-phase pie-shaped armature windings 1022 and stator cores 1021 arranged in sequence along the axial direction of the liquid storage ...

Abstract

The invention relates to a semi-active suspension energy-regenerative device of a hybrid vehicle and belongs to the technical field of energy saving and emission reduction of vehicles. A barrel-type straight line generator is integrated in a traditional passive shock absorber, and a throttling port is arranged on a piston rod to enable damping force of the shock absorber to be adjustable. When a vehicle is driven normally, the piston rod serving as an active cell and a stator perform relative motion, alternating current power is sensed in a armature winding, a battery is charged through an energy-regenerative circuit, and accordingly a part of vibration energy of a suspension system is recovered in the vehicle running process. In addition, the size of the throttling port can be adjusted according to vehicle running work conditions so as to change the damping force of the shock absorber and improve smoothness, operation stability and safety of the vehicle.

Description

technical field [0001] The invention relates to a semi-active suspension energy feeder for a hybrid vehicle, belonging to the technical field of energy saving and emission reduction for automobiles. Background technique [0002] In recent years, international oil prices have fluctuated, energy and environmental issues have become increasingly prominent, energy conservation and emission reduction, and low-carbon economy have become one of the main measures to achieve sustainable development in the country; hybrid vehicles, while maintaining the characteristics of traditional vehicles, have optimized vehicle The advantages of dynamic performance, effectively improving fuel economy, and greatly reducing exhaust emissions have attracted widespread attention and great attention from domestic and foreign automobile companies and experts and scholars in related fields; hybrid vehicles have proved their good effects in the field of energy saving and emission reduction. It is an impo...
