Abstract

PURPOSE:To increase a width of adjustment for height of a car, by guiding each pressurized oil to an oil chamber in the upper side of a rubber mount and the second oil chamber in the bottom side in a device applied to front wheels of an automobile. CONSTITUTION:A piston 22, in which a cylindrical member 15 of an internal peripheral surface is used as a peripheral cylinder, is fitted in a rubber mount 10 to form an upper side of the piston to an oil chamber 21, and pressurized oil is separately introduced from an external hydraulic pressure source to the chamber 21 through an oil supply port 23 in the upper side. The piston 22 is supported from the bottom side through a thrust member 25 by a cylindrical supporting member 24 extended upward from a spring seat 6 in the upper side of a shock absorber 2, in this way, introduction of said pressurized oil expands the chamber 21 upward, and a car body 9 is pressed by the chamber 21 and moved upward. In this way, a width of car range adjustment is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a vehicle height adjustment device that is mainly applied to the front wheels of an automobile.

In this JRtB model, there is a mount collar on the top of the hydraulic shock absorber extending upward from the axle that connects it to the car body, and a mount collar that connects it to the car body. The *g material on the upper surface and the [+O] are formed into a flexible volume aio(li) which communicates with the inside of the shock absorber via an oil passage, into which pressure oil can be freely introduced from the outside. With the introduction of the axillary pressure lever, the oil chamber was bulged upwards and the height of the axillary vehicle body was increased by 1,000 degrees.
In this case, there is a requirement to be able to freely adjust the height of the armpit vehicle body O to Kj11.

The present invention aims to obtain a device that meets these requirements.
Hydraulic pressure extending upward from the axle with i1 and O, and II
At the top of the IIl, there is an annular rubber on the outer periphery that connects it to the vehicle body side, and an upper surface OIi member that is connected to the vehicle body side, and the inside thereof is provided with an axillary buffer via an oil passage. A variable spring is formed in the oil chamber of the amO which communicates with the inside of the chamber. A variable spring 111 [0112] is interposed between the support member on the side of the container and the variable spring 111 [0112]. Pressure oil can be introduced into the spring separately from the outside.An example of the present invention will be described with reference to the attached drawings. In 0 drawings (1

At the top of 1, there is a ring-shaped mount rubber (1G) on the outer periphery that is attached to the vehicle body (9), and a pith member [υ] on the upper surface thereof that is attached to the vehicle body (9) side. Mt the Rondo (
A variable volume of oil m (13) which communicates with the lower part of the mosquito buffer @ (2) through the oil passage α extending inside 57, is supplied with pressure from an external hydraulic source through the oil supply port (14). The oil can be introduced freely (depending on the introduction of the pressure oil, for example, the second
As shown in the figure, the oil absorber II (13) expands to apply upward motion to the vehicle body (9) via the bag member aat on its upper surface.

More specifically, the mount rubber (the cylindrical member (c) fixed to the inner circumferential surface of the IIFi) is fitted onto the top of the prado (5) at the end plate of the oms and is connected to this a. ′
The cylindrical casing α8q, which is identified by rI and is fixed to the outer M4 surface, is fixed to the car body (9) through screws [fis#( The lυ was fitted onto the upper surface of the casing and fixed thereto.

Although the above is not particularly interesting with what was proposed earlier, according to the present invention, the cough mound is wrinkled under the oil chamber assembly in the cough mound, and the tearable type O rattan 2 mg on t. - a separate pressure oil introduction point from an external hydraulic source; More specifically, the piston (2), which is the cylinder with the inner periphery of the cylindrical member 7 and the outer periphery, is fitted into the mount rubber 0, and the piston (2) is formed to have an outer circumference of 11υ. A pressure oil pipe can be introduced separately from an external hydraulic source through the oil supply port (23t), and the piston @Fi** working device (

2) With the introduction of the pressure oil, the cap lυ is pushed upward by 1lJll, and the vehicle body (9) is pushed upward by this, as shown in the ms diagram. I made it move.

The oil supply port (to) is connected to the connection port (2) opened on the upper surface of the turtle member αυ through a flexible connecting pipe.

In addition, the device of the present invention can be hooked to the vehicle body (9) as shown in the figure.
In this case, a hydraulic shock absorber (9) is installed at the rear of the rear damper, which should constitute a rear damper, and the inside of the hydraulic shock absorber (I S m) at the top is connected to the cough oil chamber. @ [It shall be connected via.

To explain its operation, for example, the car body (
9) is assumed to be reduced in height to some extent as the passenger gets on the vehicle, and this state is amended by a rear Senna (not shown), and a corresponding amount of pressure oil is introduced from the outside into the oil i1 direction. This causes the iron cap 11 to expand and become, for example, in the state shown in the second figure, and the oil that communicates with it! (
13a+) is substantially the same, thus reaching the state shown in FIG. 5, where the height of the vehicle body (9) is increased in the front and rear directions and returns to substantially the original state. In such a situation or in any other situation, to further adjust the height of the body (9), a separate pressure oil in the 1N20111 of 2011W is required, according to which m *

By doing this, the height can be increased or decreased in two stages, and this can be applied to, for example, the 1IIs of the vehicle body to increase the height and width compared to the previous one. It has the advantage that it does not take up much space because it is provided inside the ring-shaped mount rubber.
