Abstract
The invention discloses an air-over-oil brake device, and belongs to the technical field of trailer braking. An oil brake axle is adopted for the device. An oil brake master pump is arranged on the middle section of the axle, and is connected with a brake air chamber, an oil pot and an oil path tee joint respectively. The oil path tee joint is connected with an oil pump brake through an oil distribution tube. The air-over-oil brake device is simple in structure, convenient to mount and low in cost, and matched connection for the conversion of air braking to oil braking is well realized.
Description
Technical field
The invention belongs to trailer braking protection valve technical field, be specifically related to gas and stop and be converted to a kind of brake mode that oil is stopped.
Background technology
The trac. locomotive of domestic production, its brake modes is generally gas and stops, the vehicle bridge of producing farm trailer employing will often adopt the serial vehicle bridge of light card according to load condition, and the braking major part of light truck bridge is all oily braking, when trailer and locomotive are supporting, cannot realize drag ，Zhe Jiugei trailer manufacturing enterprise and bring very large puzzlement, how to solve the new problem that this puzzlement ，Shi trailer manufacturing enterprise faces.
Summary of the invention
The object of this invention is to provide a kind of air-operated hydraulic brake brake gear, to solve gas that prior art oil braking vehicle bridge cannot the supporting trailer problems such as brake system of stopping.
The present invention is mainly comprised of oil pump drg and vehicle bridge, solving the technical scheme that its technical matters adopts is that vehicle bridge adopts oily braking vehicle bridge, vehicle bridge stage casing arranges oily braking master cylinder, oil braking master cylinder connects respectively compressed air brake cylinder, oil can and oil circuit threeway, and oil circuit threeway connects oil pump drg by oil expeller.
It is simple in structure adopting the good effect of invention, easy for installation, cost is low, has finely solved the supporting connection that gas braking is converted to oily braking.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is structural representation of the present invention;
1 oil pump drg, 2 oil cans, 3 oily braking master cylinders, 4 oil circuit threeways, 5 oil expellers, 6 compressed air brake cylinders, 7 vehicle bridge in figure.
The specific embodiment
As shown in the figure: vehicle bridge 7 adopts oily braking vehicle bridge, vehicle bridge 7 stage casings arrange oily braking master cylinder 3, oil braking master cylinder 3 connects respectively compressed air brake cylinder and oil circuit threeway, and oily braking master cylinder 3 connects the oil can 2 on oil can bearing by oil pipe, and oil circuit threeway 4 connects oil pump drg 1 by oil expeller 5.
While braking in trailer driving process, the high pressure gas of exporting backward from locomotive enter compressed air brake cylinder, promoting air chamber inner carrier and push rod moves backward, the plunger that push rod promotes oily braking master cylinder again moves, compression hydraulic oil enters the expansion plunger in vehicle bridge brake system, make to brake T and expand, realize braking procedure.
Claims (1)
1. an air-operated hydraulic brake brake gear, mainly by oil pump drg and vehicle bridge, formed, it is characterized in that vehicle bridge adopts oily braking vehicle bridge, vehicle bridge stage casing arranges oily braking master cylinder, oil braking master cylinder connects respectively compressed air brake cylinder, oil can and oil circuit threeway, and oil circuit threeway connects oil pump drg by oil expeller.
