Abstract

PURPOSE:To make it possible to maintain an appropriate spring constant, by adding, to the coil spring, a resilient material spacer defining therein a liquid storing space, so that the space is communicated with an accumulator through a valve which is controlled in accordance with the movable load of the automobile. CONSTITUTION:In a suspension 10 provided to each wheel, a spacer 14 is added to a coil spring 12 which is disposed between a spring sheet 24 attached to a shock-absorber 22 and an upper supprt 26. The spacer 14 made of resilient materials such as, for example, rubber, etc., is formed therein with a hollow space 28, and is formed in a coil-like shape having the same pitch as that of the cil spring 12, the space 28 being filled with liquid such, as for example, oil and as well being communicated with an accumulator 16 through a pipe line into which a valve 18 is disposed. Further, in accordance with the output of a sensor 20 for detecting the load of the vehicle, a controller 40 closes the valve 18 when the vehicle load exceeds a predetermined value to increase the spring constant of the coil spring 12.

In other words, when the suspension springs are made softer, the ride comfort is good when the load is small, but when the load is large, the ride comfort decreases, and the vehicle body posture changes more easily, reducing stability. . Conversely, if the suspension spring is made stiffer, the ride comfort is good when the load is large, but the ride comfort deteriorates when the load is small.

。As shown in FIG. 2, the spacer 14 is made of an elastic material such as rubber, and is formed in a hollow shape with a space 28 inside and in a coil shape having the same pitch as the coil spring 12. The spacer 14 has grooves 30 on the upper and lower sides, and the grooves 30
0 is fitted into the helical portion 13 of the coil spring 12 and arranged along the helical portion 13. Oil or other liquid is contained in the space 28 of the spacer 14. By allowing this liquid to enter and exit, the spacer 14 changes the effective number of turns of the coil spring 12 and changes the spring constant of the coil spring 12. To this end, the spacer 14 is formed to have a length spanning an appropriate number of turns of the coil spring, depending on the range of the spring constant to be varied.

It is incorporated into the piping 38 and communicates or blocks the space 28 of the spacer 14 and the accumulator 16. This valve 18 receives a signal from a sensor 20 via a controller 40 and receives a signal from a sensor 20.
When a signal is being output from 0, the controller 40 and the power supply 42 act to shut it off. The sensor 20 is, for example, a pressure switch disposed within the shock absorber 22 and detects the load of the vehicle body acting on the coil spring 12.

る標準のばね定数をもたらす。(Operation of the first embodiment) When the load is light such as when one person is on board, the sensor 20 does not output a signal, so the valve 18 is in an open state, and the space 28 of the spacer 14 and the accumulator 16 are in communication. . As a result, when the coil spring 12 is compressed, the liquid in the space 28 will flow towards the accumulator 16,
Due to the sufficient elastic deformation of the spacer 14, the part of the coil spring 12 that engages this spacer 14 deforms and exhibits a spring action, resulting in a standard spring constant given by the total number of turns of the coil spring 12.

A signal is output from the sensor 20. This signal is transmitted to the controller 40
The signal is converted into a signal that enables the valve 18 to be actuated, and the valve 18 is actuated to shut off.

積載量に応じてばね定数を変えることができる。As a result, the space 28 of the spacer 14 is
When the coil spring 12 is compressed, the spacer 14 cannot be deformed. Therefore, the portion of the coil spring 12 that is engaged with the spacer 14 cannot be deformed, and the coil spring 12 cannot be deformed. 12 reduces the effective number of turns,
It comes to exhibit a large spring constant. In this way,
The spring constant can be changed depending on the load capacity.

A cylindrical member 62 fixed to the piston rod 61 of the shock absorber 60, and a diaphragm 64 fixed to the cylinder 63 and the cylindrical member 62 of the shock absorber 60.
An air chamber 66 is defined by these. This air chamber 66
An air spring 52 is formed by the air filled inside.

助空気室６８の体積を定めることができる。。The tank 54 includes an auxiliary air chamber 68 .
8 communicates with the air chamber 66 of the air spring 52 via a pipe 70. Since the spring constant of the air spring 52 changes depending on the volume of the air chamber, the volume of the auxiliary air chamber 68 can be determined depending on the range of the spring constant to be changed. .

It is incorporated into the piping 70 to communicate or cut off the air chamber 66 and the auxiliary air chamber 68. This valve 56 receives a signal from the sensor 58 via the controller 72, and when the signal is output from the sensor 58, the valve 56 is shut off by the action of the controller 72 and the power source 74.

This leveling valve 76 detects changes in vehicle height and adjusts the amount of air supplied to the air chamber 66 of the air spring 52 via the air compressor 78, air dryer 80, reservoir tank 82, and pressure control valve 84. Keep vehicle height constant regardless of load.

However, with a single pressure switch, there is a possibility that the pressure switch opens and closes due to vibrations while the car is running, causing chattering, and that it is sufficient to judge the load when the car is stopped. For the reason, Sen, Su5
8 and controller 72 preferably have the configuration shown in FIG. 4. The illustrated sensor 58 includes three pressure switches 86.8.
7.88 and one vehicle speed sensor 90, and three pressure switches are arranged, for example, in relation to one front wheel and two rear wheels. The output from each pressure switch is connected to an amplifier 9
2 and then input to the AND circuit 94. On the other hand, the output of the vehicle speed sensor 90 is converted into a voltage by a frequency-voltage converter 96, the sign of which is inverted, and the result is input to a comparator 98.

This state will be explained with reference to the time chart of FIG. When the automobile is stopped (A), the comparator 98 outputs signal 1. At this time, for example, when cargo is loaded (B), the AND circuit 94 outputs a signal l. As a result, the valve 56 is activated (C
), the spring constant becomes large because the air chamber 66 and the auxiliary air chamber 68 are shut off. The valve 56 is then held in this state. Therefore, even if the car is not running (D) and the signal from the comparator 98 becomes O, or if rolling occurs while the car is running (E), the signal from one of the pressure sensors 86 to 88 becomes O, and the AND circuit Even when the signal from 94 becomes O, the valve 56 is in a closed state and the spring constant of the air spring 52 is kept large.

outputs a signal of 0, so the valve 56 is inactive (G)
, since the air chamber 66 and the auxiliary air chamber 68 communicate with each other,
The spring constant of the air spring 52 becomes smaller.

As a result, when the load is small, the spring constant of the suspension spring is reduced, and when the load is large, the spring constant is increased, making it possible to obtain almost the same ride quality regardless of the load. Therefore, it is particularly suitable for commercial vehicle suspensions.
