Embodiment Construction

[0026] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0027] Such as Figure 1 to Figure 3 As shown, the brake control device 10 according to this embodiment includes a housing 11 in the shape of a rectangular box. The inside of the housing 11 serves as a housing space capable of housing a brake pressure control valve 20 , a control board 28 and the like which will be described later. The housing 11 has a housing main body 12 with an open front, and a cover 13 capable of opening and closing the opening of the housing main body 12 .

[0028] Such as image 3 As shown, the rear wall 12a, which is one of the side walls of the housing body 12, is stepped. The rear wall 12a has a shape in which the upper side of the step protrudes further rearward. A stem 14 is attached to the lower side of the step of the rear wall 12a. The rear surface (back surface) of the stem 14 is substantially flush with the upper...

Abstract

Disclosed is a brake pressure control valve 20 that is provided with: a block 31 in which at least first hole parts 31a, 31b and two second hole parts 31c, 31c are formed; a variable load valve that is disposed in the first hole parts 31a, 31b and capable of generating variable load pressure according to a vehicle load; and relay valves 22, 22 that are disposed in the second hole parts 31c, 31c respectively and capable of generating brake pressure. The relay valves 22 are provided with diaphragms 22f that are disposed so as to project laterally from pistons 22e and supporting the pistons 22e while allowing the piston to reciprocate. The two relay valves 22, 22 are disposed in horizontal alignment with a space therebetween such that the diaphragms 22f thereof are mutually adjacent. The variable load valve is disposed in a position between the two pistons 22e and away from a position where the diaphragms 22f are mutually adjacent.

Description

Technical field [0001] The invention involves braking pressure control valves and braking control devices. Background technique [0002] In the past, as the following patent literature 1 was made public, it was known that there were braking control devices that will be adopted with the re -adjustment valve and relay valves in the shell.In the shell of the braking control device disclosed by the patent literature, the two forms of the composition of the relay valve (relay valve block) are set toThese blocks are tightly accommodated. [0003] On the other hand, if the 2 patent documents are made public, it is known that there are braking control devices for preventing the gliding valve that prevent wheel taxi.Patent Literature 2 opens the publicized valve from the solenoid valve and the control valve, and the solenoid valve receives the control signal.The control valve has the control room and the output room connected to the brake cylinder connected to the reunification of the so...
