Description

Energy regeneration for suspension systems

technical field

The utility model relates to a regeneration device. More specifically, the utility model relates to an energy regeneration device for a suspension system, which can regenerate the energy generated during the buffering process of vibration and/or impact transmitted from the road surface when the vehicle is running. The vehicle is preferably a bulldozer. the

Background technique

It is generally known that vehicles, especially bulldozers, travel on very harsh and complicated road conditions, and are subject to vibrations when driving. These vibrations are considered undesirable. In fact, much effort has been put into the development of suspension systems, including springs, damper assemblies, etc., which provide vehicle stability and isolate the passenger generated when driving on a winding road. Currently, the energy associated with these vibrations is lost, usually primarily by the shock absorbers of the vehicle suspension converting it into heat dissipation. If these harmful vibration energies can be recovered and converted into directly usable energy forms for the vehicle, the energy consumption of the active suspension can be reduced, so that the vehicle can reduce operating costs while improving ride comfort. the

Accordingly, it would be desirable to provide a system for harvesting energy associated with vehicle vibrations to generate usable power and a system configured to use such power. the

Basically, the suspension device of a vehicle has a link or links for connecting the body, it is supported in the vertical direction using chassis springs and shock absorbers, and it is capable of adjusting the body and wheels by adjusting stiffness and elasticity relative movement of the level. the

The suspension system needs to provide comfort characteristics by avoiding irregular inputs of various road conditions when the vehicle is running, and the suspension system needs to provide stability characteristics when the vehicle turns or brakes. the

As shown in FIG. 2, the general structure of the suspension system includes: a joint 103 for rotatably supporting a wheel 101; and a lower arm for connecting a lower portion of the joint 103 with a vehicle body. The upper part of the joint 103 is connected to the lower part of a support rod (shock absorber) 107 , and the upper part of the support rod 107 is mounted to the vehicle through a top bracket 109 . the

The upper spring seat 113 and the lower spring seat 115 are arranged on the support rod 107 , and the chassis spring 111 is configured between the upper spring seat 113 and the lower spring seat 115 . The chassis spring 111 can reduce the impact from the road surface, and the support rod 107 can reduce the free vibration of the chassis spring 111, so that driving comfort can be enhanced. An end portion of a stabilizer bar 117 configured to the vehicle body is connected to the support rod 107 via a connection link 119, and the stabilizer bar 117 controls shaking of the vehicle body. the

As described above, the strut type suspension system is structurally uncomplicated and inexpensive, ensures a large space, and also allows a small change in the layout of the wheel 101 according to the installation position. the

The strut type suspension system repeats bumping and bouncing according to driving conditions, and the chassis spring 111 repeats compression and extension to reduce the impact from the road surface. The chassis springs 111 generate kinetic energy through compression and extension; however, this kinetic energy is not made useful again. the

As shown in Figure 3, a kind of automobile energy regenerative shock absorber comprises an upper working cylinder, a lower working cylinder, a recuperation motor, a motion conversion mechanism and a transmission mechanism; the lower working cylinder is slidably connected to the upper working cylinder ; The motion conversion mechanism converts the linear motion caused by the vibration of the car wheel into a rotary motion; the transmission mechanism transmits the rotary motion to the energy recovery motor, and generates electric energy through the energy recovery motor; the motion The conversion mechanism is installed in the lower working cylinder, which is a ball screw pair, including a ball screw and a screw nut; the screw nut is connected to the lower working cylinder, and the ball screw is installed on the upper working cylinder and An upper main shaft is provided to be connected to the transmission mechanism; the transmission mechanism includes a first overrunning clutch and a second overrunning clutch, which are respectively connected to the ball screw, and the clutching directions of the two overrunning clutches are opposite to each other. However, this kind of energy regeneration equipment has disadvantages such as high cost, complex structure, and low efficiency. the
