Abstract

The utility model provides an air brake system for a mine vehicle, which comprises a compressor, an air cylinder, a front brake chamber, a rear brake chamber, a relay valve, a hand brake valve and a foot brake valve which are connected by air circuits. A pipeline from an outlet of the compressor (1) to the air cylinder is provided with a four-circuit protection valve (4). Four output ports of the four-circuit protection valve (4) are respectively connected to air inlets of a front parking air cylinder, a front braking air cylinder, a rear parking air cylinder and a rear braking air cylinder to make air circuits of the front parking air cylinder, the front braking air cylinder, the rear parking air cylinder and the rear braking air cylinder connected in parallel. Two-way check valves (15) are respectively arranged at the lower parts between an air inlet of the hand brake valve and the front parking air cylinder and between the air inlet of the hand brake valve and the rear parking air cylinder. Front and rear service brake circuits of the utility model can realize the independent braking action and when one pipeline is broken and brake is in failure, the other brake circuit can still realize the independent service braking action, thus, the safety of the brake system is improved.

Description

A kind of mining car Pneumatic braking system
Technical field
The utility model relates to a kind of mining car Pneumatic braking system, belongs to the vehicle brake technology field.
Background technology
At present, in the vehicle of mining car Pneumatic braking system, generally has only the back axle parking braking function, safety factor behind single back axle parking-brake action is lower, particularly on the ramp during braking during standstill, because of the quality of mining car self bigger, inertia is bigger, occurs safety misadventure easily; In addition, the brake system of a lot of mining cars is the serially connected air storages of air tank, and front and back bridge brake circuit links together, and does not have independent gas supply system, and when a certain pipe breakage, the safety traffic accident easily takes place braking failure.
Summary of the invention
The purpose of this utility model is to design a kind of mining car Pneumatic braking system, increases the propons parking braking function on the one hand, arrives the function of doube bridge Parking, thereby makes the car load performance of parking brake more safe and reliable; The barometric brake circuit system that drives a vehicle on the other hand is independent, and when a certain pipe breakage wherein, during braking failure, another brake circuit still can be realized independent driving braking maneuver.
The technical solution of the utility model is: mining car Pneumatic braking system of the present utility model comprises by gas circuit bonded assembly compressor, air receiver, preceding compressed air brake cylinder, back compressed air brake cylinder, relay valve, hand brake valve, foot brake valve; to the pipeline of air receiver, four-loop protection valve is installed at compressor outlet; four delivery ports of four-loop protection valve are connected respectively to the admission port of preceding Parking air receiver, preceding braking air receiver, back Parking air receiver, back braking air receiver, the gas circuit parallel connection of Parking air receiver, preceding braking air receiver, back Parking air receiver, back braking air receiver before making.
Described mining car Pneumatic braking system, the bottom of installing between the admission port of hand brake valve and preceding Parking air receiver and back Parking air receiver is installed the bilateral check valve respectively.
Advantage of the present utility model: the utility model increases the propons parking braking function, arrives the function of doube bridge Parking, thereby makes the car load performance of parking brake more safe and reliable; In addition, design driving barometric brake circuit system is independent, and the independent brake action can be realized in service brake loop, front and back, when a certain pipe breakage wherein, during braking failure, another brake circuit still can be realized independent driving braking maneuver, the safety that has improved brake system.
