Abstract

A gear vehicle parking brake and gear combined control system comprises an oil tank, a filter, a hydraulic pump, a parking brake valve, a parking hydraulic cylinder, a parking brake, a hydraulic control air valve, an air pocket, a gear selecting reversing valve, a gear shifting reversing valve, a gear selecting cylinder and a gear shifting cylinder. The combined control on parking brake and the gear shifting is realized, so a vehicle cannot be subjected to gear selecting or gear shifting at the parking brake state and cannot advance, and the problem that a friction pad of the parking brake is easily abraded as the vehicle at the parking brake state advances by being put into gear is solved.

Description

Vehicle parking braking and gear combined control system
Technical field
The utility model relates to a kind of vehicle parking braking and gear combined control system.
Background technology
According to safety regulations in coal mine, the vehicle under coal mine all needs to arrange service braking system, emergency brake system and parking brake system, and emergency braking and stopping brake are a set of brake system conventionally.The vehicle moving under coal mine, when vehicle does not start, must allow vehicle in stopping brake state.When needs actuating vehicle, often there is driver not remove stopping brake just by vehicle take-offs, the friction lining of parking brake is very easy to abrasion like this, causes the frequent control wafer of rubbing that needs to change.
Utility model content
The purpose of this utility model be to propose a kind of cannot block selecting when stopping brake, vehicle parking braking and the gear combined control system of gearshift.
For achieving the above object, the utility model is taked following technical scheme: the braking of this vehicle parking comprises fuel tank, filter, Hydraulic Pump, stopping brake valve, parking hydraulic actuating cylinder, parking brake, hydraulic control air valve, gas bag, block selecting change-over valve, gearshift change-over valve, gear-selecting cylinder, shifting cylinder with gear combined control system, the oil inlet of Hydraulic Pump is connected with fuel tank by filter, the oil outlet of Hydraulic Pump is connected with the oil inlet P mouth of stopping brake valve, the oil outlet A mouth of stopping brake valve is connected with the control mouth K mouth of parking hydraulic actuating cylinder and hydraulic control air valve respectively by two oily passages, the hydraulic cylinder-controlled stop vehicle brake that stops moves, the admission port P mouth of gas bag and hydraulic control air valve is connected, the air extractor duct A mouth of hydraulic control air valve is connected with first, the second gas passage, first, the second gas passage respectively with the admission port P mouth of block selecting change-over valve, the admission port P mouth of gearshift change-over valve connects, block selecting change-over valve and gearshift change-over valve are controlled respectively gear-selecting cylinder and shifting cylinder action.
Between the oil outlet of described Hydraulic Pump and fuel tank, be provided with oily passage, in oily passage, be provided with safety valve.
The utlity model has following good effect: the utility model has realized stopping brake and gearshift jointly controls, vehicle cannot be put into gear at stopping brake state, vehicle can not be walked, and having solved puts into gear to walk at stopping brake state vehicle causes the easily problem of wearing and tearing of parking brake friction lining.Vehicle under the utility model suitable coals mine, is also applicable to have on ground the vehicle of stopping brake.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Embodiment
See accompanying drawing, the braking of this vehicle parking comprises fuel tank 1, filter 2, Hydraulic Pump 3, safety valve 4, stopping brake valve 5, parking hydraulic actuating cylinder 6, parking brake 7, hydraulic control air valve 8, gas bag 9, block selecting change-over valve 10-1, gearshift change-over valve 10-2, gear-selecting cylinder 11-1, shifting cylinder 11-2 with gearshift combined control system;
The oil inlet of Hydraulic Pump 3 is connected with fuel tank 1 by filter 2, the oil outlet of Hydraulic Pump 3 is connected with the oil inlet P mouth of stopping brake valve 5, the oil outlet A mouth of stopping brake valve 5 is connected with the control mouth K mouth of parking hydraulic actuating cylinder 6 and hydraulic control air valve 8 respectively by two oily passages, and parking hydraulic actuating cylinder 6 is controlled parking brake 7 actions.The admission port P mouth of gas bag 9 and hydraulic control air valve 8 is connected, the air extractor duct A mouth of hydraulic control air valve 8 is connected with first, second gas passage, first, second gas passage is connected with the admission port P mouth of block selecting change-over valve 10-1, the admission port P mouth of gearshift change-over valve 10-2 respectively, and block selecting change-over valve 10-1 and gearshift change-over valve 10-2 control respectively gear-selecting cylinder 11-1 and shifting cylinder 11-2 action.
Between the oil outlet of Hydraulic Pump 3 and fuel tank 1, be provided with drainback passage, safety valve 4 is arranged in this drainback passage.
Under normal motoring condition, P mouth and the A mouth of stopping brake valve 5 communicate, and the oil of Hydraulic Pump 3 outputs enters parking hydraulic actuating cylinder 6 by stopping brake valve 5, and parking brake 7 is in braking mode not.The oil that the A mouth of stopping brake valve 5 flows out promotes 8 actions of hydraulic control air valve, and P mouth and the A mouth of hydraulic control air valve 8 communicate, and the gas of gas bag 9 enters block selecting change-over valve 10-1 and gearshift change-over valve 10-2, the block selecting of vehicle energy and gearshift by hydraulic control air valve 8.
During stopping brake, handle stopping brake valve 5, making stopping brake valve 5 is that P mouth and the A mouth of stopping brake valve 5 do not communicate in the position shown in the figure 1, the oil of Hydraulic Pump 3 outputs can not enter parking hydraulic actuating cylinder 6 by stopping brake valve 5, the hydraulic actuating cylinder 6 that stops does not have pressure oil, parking hydraulic actuating cylinder 6 is under the effect of spring, drive parking brake 7 brakings, now the K mouth of hydraulic control air valve 8 does not have pressure oil, making hydraulic control air valve 8 is that P mouth and A mouth do not communicate at state shown in Fig. 1, and the gas of gas bag 9 can not enter block selecting change-over valve 10-1 and gearshift change-over valve 10-2.Now, even if operation block selecting change-over valve 10-1 and gearshift change-over valve 10-2 can not make gear-selecting cylinder 11-1 and shifting cylinder 11-2 action, vehicle is not just hung gear, cannot walk.
