Abstract
The utility model discloses a gas cap oil braking device and belongs to the technical field of trailer brake. According to the device, an oil brake vehicle axle is adopted, an oil brake master cylinder is arranged in the middle section of the vehicle axle, the oil brake master cylinder is connected with a brake chamber, an oil can and an oil-way T-joint, and the oil-way T-joint is connected with an oil pump brake through an oil distributing pipe. The gas cap oil braking device is simple in structure, convenient to install, low in cost and capable of well achieving matching connection for conversion from gas brake to oil brake.
Description
Technical field
The utility model belongs to trailer braking protection valve technical field, is specifically related to gas and stops 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, this brings very large puzzlement just to trailer manufacturing enterprise, how solving this puzzlement, is the new problem that trailer manufacturing enterprise faces.
Summary of the invention
The purpose of this utility model 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 utility model is mainly made up 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 utility model, easy for installation, cost is low, the fine supporting connection that has solved gas braking and be converted to oily braking.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is the utility model structural representation;
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)
