Description

[Detailed description of the invention] Purpose of the invention The present invention aims to simplify the mounting equipment of a link device that transmits the variable spring force of a load sensor spring to a hydraulic pressure control mechanism in a load-responsive hydraulic pressure control system for an automobile, and to increase the degree of freedom in mounting. This paper proposes a simple configuration to measure the increase.

BACKGROUND ART FIG. 3 shows a conventionally known load-responsive brake fluid pressure control device, in which a housing (hydraulic pressure control valve main body) 2 containing a control valve 1 is coupled to a sprung member of a vehicle. A lever 5, which is a lever member, elastically contacts the plunger 3 of the control valve 1 at the point of action 4.
One end is used as a fulcrum part 6 and is engaged with the housing 2, the other end is used as a force point part 7 and one end of a resilient member 8 is attached, and the other end of the resilient member 8 is engaged with an unsprung member of the vehicle.

With the above configuration, the relative positional relationship between the sprung and unsprung parts of the vehicle is detected via the elastic member 8 and the lever 5, and the hydraulic pressure B is transmitted to the plunger 3 of the control valve 1 from the master cylinder A to the rear wheel cylinder.
It controls the

Problems to be Solved by the Invention In the conventional load-responsive brake fluid pressure control device as described above, as shown in FIG.
Because the fulcrum part 6 was provided in the housing 2, there were restrictions on the shape of the bracket that supported the hydraulic control valve housing on the vehicle side, and the direction of the discharge port on the side of the housing (see Figure 1 C) was changed. had the problem that it was necessary to create a new cast for that purpose.

Means for Solving Problems The present invention is a load-responsive brake fluid pressure control device that detects the relative position of sprung and unsprung parts of a vehicle and controls brake fluid pressure. A lever comprising a housing containing a control valve, an elastic member having one end attached to the unsprung side of the vehicle, and a lever member, one end of the elastic member being attached to the force point of the lever, and the force point of the lever making contact with the hydraulic pressure control valve. and a fulcrum member that serves as a fulcrum of the lever and is rotatably attached to the housing, and a fixing member that positions the fulcrum member and the housing;
The present invention is characterized in that the setting direction of the lever relative to the housing can be freely set by changing the position of the fixing member.

Example The present invention will be explained below with reference to the accompanying drawings.

Figures 1 and 2 each show an embodiment of the present invention. In Figure 1, the numbers 1 to 8 are the same as in Figure 3, 1 is a control valve, 2 is a housing (control valve body), and 3 is a Plunger, 4 is an action point, 5 is a lever (lever member), 6 is a fulcrum, 7 is a force point, 8
is a resilient member.

The difference from FIG. 3 is that a fulcrum member 10 configured as a separate member from the housing 2 is attached to one end of the housing 2 via a pin 11 as a fixing member (see FIG. 1B). One end of the lever 5 is fitted onto a fulcrum portion 6 that protrudes from a part of the lever. 10' is a fulcrum receiving groove at the end of the lever, and 11' is a pin receiving slit.

According to the configuration of the present invention, the fulcrum member 10 is removable from the housing 2, and can be easily arranged in any desired arrangement by changing the position of the pin 11. Therefore, as shown in FIG.
If the vehicle is installed upside down, this can be easily handled by changing the position of the pin.

Of course, the fixing member is not limited to a pin.

FIG. 2 shows another embodiment of the present invention, in which a bracket 13 is attached to a housing 2 on a vehicle body 15.
The fulcrum member 10 is positioned and supported by a pin 14 connected to the bracket 13, and the object of the present invention is the same as that shown in FIG.

Effects of the invention According to the invention configured as described above, the fulcrum member for configuring the fulcrum part of the load transmission lever can be placed separately from the control valve housing, and can be set to be rotatable with respect to the housing. Therefore, it is possible to achieve the effect that the vehicle layout is facilitated and restrictions on the shape of the bracket on the vehicle side can be reduced.
