Abstract

PURPOSE:To raise the shock absorbability and ride feelingness of a vehicle even on bad road by a method in which a buffer means is made up of a usual spring and a shape-memory alloy spring, and the shape-memory alloy is heated on the basis of the differences between detected vibration and set value to restore it to its original shape. CONSTITUTION:A buffer means is made up of a usual spring and a shape-memory alloy 20. Detection signal from an acceleration sensor 23 is put in a comparator 30 and compared with signals from a setter 31. When the acceleration signal 23 is below a set value, during the running period for flat ground, no output is sent out from the comparator 30, the shape-memory alloy spring 20 is kept at ordinary temperature, and only the usual spring operates in suspension 15. When acceleration signal 23 exceeds a set value 31, signal is put in a drive circuit 32, the switch 35 of a power source circuit 33 turns ON, and the shape- memory alloy spring 20 is electrically energized and heated. The shape of the spring 20 is restored to its original one and a given spring pressure is recovered. Therefore, the spring pressure is added, vibration absorbability is increased, and ride feelingness is raised.

Description

【発明の詳細な説明】 技術分野 この発明は、自動車○懸架装置に適用されるンヨノクア

伝わるのを防ぎ、駆動力、制動力。BACKGROUND ART As is well known, this type of suspension system supports the weight of the vehicle body via the wheel axle, prevents wheel vibrations from being directly transmitted to the vehicle body, and increases driving force and braking force.

伝わらないように防止している。This is to transmit lateral force during steering from the wheels to the vehicle body, improve ride comfort, and prevent excessive loads from being applied to various parts. Such a suspension system is equipped with a shock absorber that generates damping force through the action of a spring.
This damping force absorbs car vibrations, suppresses car movement, or temporarily absorbs the impact force applied to the wheels to alleviate the impact effect and prevent it from being transmitted to the car body. It is prevented.

を著るしく阻害するという問題も生ずる。By the way, in the conventional nuclide 7 Yonoku absorber, if the spring pressure of the buffer spring is set to be strong and hard, and the damping force is set high to suppress the movement of the car, the ground contact of the car will be improved and stable driving performance will be ensured. On the other hand, bumps and vibrations due to irregularities and undulations on the road become more intense, resulting in poor ride quality and comfort.If the spring pressure is set to be soft and the damping force is set to a low value in an attempt to obtain a comfortable ride, the ground running performance will be affected. There were contradictory issues such as being negative. Furthermore, if the spring pressure is weakened and the damping force is set to a low value, for example, when an impact force is applied to the 111 wheel due to an uneven road surface, the vehicle body will be pushed up and agitated, causing large vibrations or causing large vibrations in the vertical and horizontal directions. Shaking may occur, and it takes time to attenuate and absorb such vibrations and large tremors, making it impossible to quickly recover to a stable running condition. The problem of doing so also arises.

In addition, when an impact force is applied to the wheels due to an uneven road surface, the spring pressure of the buffer spring is temporarily increased to quickly reduce vibrations and large shaking of the car body caused by this impact force. The purpose is to absorb attenuation.

せるように構成する。In order to achieve this object, the present invention provides a shock absorbing section (socket) consisting of a normal spring and a shape memory alloy spring between the vehicle body and the axle, and a shock absorbing section (socket) made of a normal spring and a shape memory alloy spring is inserted between the vehicle body and the axle to prevent vibrations applied to the axle.
is equipped with a sensor that detects acceleration, and also has a means for heating the shape memory alloy spring to return to its shape when the detection output of the sensor exceeds a preset I7 setting output, and the shape memory alloy spring is heated to restore its shape to the wheel due to unevenness of the road surface, etc. When an impact force is applied, the spring pressure of the normal spring is combined with the spring pressure of the shape memory alloy spring to temporarily make the spring pressure of the shock absorbing member stronger and harder, increasing its damping force, and also under normal driving conditions. In this case, the buffering effect of the buffering member is normally performed only by the spring pressure of the spring.

In addition, when an impact force is applied to the wheel, that is, the axle that supports it due to unevenness of the road surface, the shape memory alloy spring is restored to its shape, and the spring pressure is added to the spring pressure of the normal spring, and the cushioning member Since the spring pressure acts strongly and hard9, and its damping force is temporarily set high, the impact force is quickly absorbed by 1, and the impact force is quickly absorbed. Large tremors in this direction are quickly attenuated and absorbed. In addition, shape memory alloy springs have excellent responsiveness, so they can provide quick and responsive driving stability even on rough roads with uneven and undulating surfaces. Regardless of the speed, stable and good running performance can be obtained at all times, and ride quality and comfort are also improved.

A coil spring 20 made of a shape memory alloy (hereinafter referred to as a memory alloy spring) is arranged in parallel with the normal spring 18.

Terminals 21 and 22 connected to a power supply circuit 33 are provided at both ends of the memory alloy spring 20-.

The power supply circuit 33Ir, r consists of a power supply 34 and a switch 35 for turning it on and off, and is connected between the terminals 21 and 22 of the memory alloy spring 20.

Therefore, no signal is output from the comparator 30, and all the memory alloy springs 20 are maintained at room temperature. This is done only by the spring pressure of the suspension 15, and that spring pressure acts softly.
・The damping force for shooting and impact is adjusted to a slightly lower level to maintain good ride quality and comfort.

Then, the sensor 23 detects vibration or acceleration caused by this impact force and outputs a detection signal corresponding to this to the comparator 30. The comparator 30 compares and calculates the detection signal from the sensor 23 and the setting output from the setting device 31, and sends a signal to the drive circuit 32 whenever the detected value exceeds a preset setting value. The drive circuit 32 is driven by this signal, and the switch 3 of the power supply circuit 33 is driven.
Turn on 5. As a result, all the memory alloy springs 20 provided in each suspension 7 yon 15 are connected to the power source 34.
The spring is heated by electricity and instantaneously returns to its initial state, and at the same time, the spring pressure is restored to the desired set pressure. As a result, the spring pressure of each suspension 15 is
The spring pressure caused by the memory alloy spring 20 is added to the spring pressure caused by the memory alloy spring 20, and the spring pressure is increased to be equal to the sum of both. Therefore, the spring pressure temporarily acts more strongly than when the vehicle is running on flat ground, and the damping force value against vibrations and shaking is set high. Therefore, the impact force applied to the front wheels 12 is quickly absorbed and buffered at that point, and at the same time, vibrations and large shaking of the vehicle body caused by this impact force are quickly damped and absorbed with good response. In this case, since the memory alloy spring 20 has extremely good responsiveness and returns to its shape instantly, phenomena such as shock absorption, vibration of the vehicle body, and large shaking are attenuated and absorbed in a very short period of time and are eliminated. Therefore, vibrations and large tremors do not continue for a long time even after passing the unevenness A as in the conventional case, and a stable running state can be quickly recovered in a short time.

その後、車が安定走行状態に回復すると、記憶合金バネ

The shape may be restored by heating.

In this way, it is possible to switch and adjust the damping force value by the spring in a plurality of high and low levels corresponding to the impact level according to the unevenness of the road surface.

You can select and adjust the damping force value to suit your preference.
