Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is converter inner structure schematic diagram of the present invention;
Fig. 2 is converter external structure schematic diagram of the present invention.
The specific embodiment
The embodiment of converter for a kind of air-pressure disc brake as depicted in figs. 1 and 2, comprise converter shell 4, described housing is provided with the input port 40 joining with compressed air brake cylinder and the delivery port 41 joining with braking clamp body, described input port is vertical with delivery port direction, in described housing, be provided with connecting rod mechanism, compressed air brake cylinder depression bar move through linkage transmission to braking clamp body internal mechanism.
Described connecting rod mechanism comprises pressure arm 1 and a push rod 6 of a V-arrangement, and described pressure arm bottom is rotatably connected in housing, and described pressure arm right edge top and depression bar join, and described pressure arm top, limit, left side and push rod front end are hinged.Between described pressure arm bottom and described inner walls, be provided with a pull back spring 5 that makes pressure arm reply original position after braking is removed.Described pressure arm right edge top lateral wall is provided with circular arc recess 10 and joins with depression bar end, top, limit, described pressure arm left side lateral wall is provided with semi-circular recesses 11, the dual-side top of described semi-circular recesses is provided with semicircle lug, one bearing pin is through the center of circle of described semicircle lug, and the angle between limit, the described pressure arm V-arrangement left and right sides is acute angle.Described push rod front end is provided with round end 60, and the described round end center of circle is provided with the pin-and-hole passing for bearing pin, and described round end joins by necking down and push rod main body, and described push rod rear end is provided with cap head 61.Described pressure arm is rotatably connected on housing by anchor shaft 3, is provided with bearing 2 between described pressure arm and anchor shaft.Described housing madial wall between input port and delivery port is V-arrangement wall, and limit, described V-arrangement wall left side is vertical with input port plane, and the angle on described V-arrangement wall right edge and limit, V-arrangement wall left side is obtuse angle.Described housing input port and delivery port lateral surface are large end face, housing parts 42 width and delivery port equal diameters between input port and delivery port, and between input port and delivery port, housing parts is arc transition structure.The V-shaped part of pressure arm inner side is arc transition structure, and housing V-arrangement wall is also arc transition structure.
Pressure arm 1 is connected to form force transferring lever mechanism with push rod 6 by bearing pin, by bearing 2, anchor shaft 3, force transferring lever mechanism is fixed on to converter shell 4 inside again, wherein 1 body structure of pressure arm is V font, and push rod 6 can rotate freely certain angle around bearing pin.
Principle of work of the present invention:
When vehicle in the process of moving, while braking as needs, there is the depression bar of compressed air brake cylinder or spring brake chamber to promote pressure arm 1, because the force transferring lever mechanism being comprised of pressure arm 1 and push rod 6 is fixed in converter shell 4 by bearing 2, so promote to cause push rod 6 outwards to move after pressure arm 1, the mechanism that promotes braking clamp body inside starts vehicle to brake.
When braking is removed, both after the depression bar return of compressed air brake cylinder or spring brake chamber, the power that pressure arm 1 neither one is downward, by the elastic deformation of pull back spring 5, promote fast pressure arm 1, make force transmission mechanism fast speed return, the power of brake off caliper, completes the process that braking is removed.
On having, can obtain, the present invention is a mechanical transmission mechanism between compressed air brake cylinder or spring brake chamber and braking clamp body, has realized the transmittance process of power, and this conv mechanism is simple, uses steadily, and noise is low, and volume is little, quality is light.Especially:
Conv mechanism novelty, only having two end in contact air chambers or spring brake chamber and braking clamp body is large end face, and remainder is arc transition, and arc transition place width is little, substantially about the same with input port and delivery port diameter, thereby reduced and the interference of extraneous remaining part.
Conv is suitable for and current multiple commercial vehicle/comm..vehicle air-pressure disc brake, without dividing of left and right, production and processing, easy to assembly.
Conv can change air chamber or the setting angle of spring brake chamber on drg, and traditional air chamber or spring brake chamber setting angle are parallel with vehicle bridge, vertical with vehicle bridge by conv rear gas chamber or spring brake chamber.
