Abstract
The utility model relates to a vehicle brake control device which comprises a brake pedal, a push rod which is connected with the brake pedal, a brake which is connected with the push rod, a booster arranged between the push rod and the brake, a gas outtake tube of a vacuum bucket is connected with the booster and a gas intake tube of the vacuum bucket is communicated with a gas outtake tube of a vacuum pump. An oil inlet and an oil outlet of the vacuum pump are respectively connected with a grease tube of a diesel engine and an oil outlet screw hole of a sump through oil tubes. The brake is powered through that the vacuum pump is circularly greased by the grease in the single-cylinder diesel engine and a vacuum cylinder is vacuumed by the vacuum pump. The utility model has flexible and ease brake, high safety and reliability, compact structure, reasonable layout and convenient installation.
Description
Technical field
The utility model relates to a kind of vehicle brake control apparatus, is a kind of single cylinder diesel three-wheel vehicle vacuum booster brake device specifically.
Technical background
Along with the increasing of the tire that agriculture truck adopted, drg is also increasing, and brake operation just becomes distinct issues, and it is too big to show as brake pedal resistance, and braking effect is bad.Multi-cylinder diesel engine generally carries vacuum pump, can be equipped with vacuum booster brake device easily; Single cylinder diesel can not be installed vacuum booster brake device owing to be not with vacuum pump, and braking effect is bad.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, can be installed in the single cylinder diesel three-wheel vehicle vacuum booster brake device that uses on the single cylinder diesel.
For achieving the above object, the utility model adopts following technical scheme:
Single cylinder diesel three-wheel vehicle vacuum booster brake device described in the utility model comprise brake pedal, with brake pedal bonded assembly push rod, with push rod bonded assembly drg, between push rod and drg, have servo-unit, servo-unit is communicated with the freeing pipe of vacuum barrel, the air inlet pipe of vacuum barrel is communicated with the freeing pipe of vacuum pump, and the oil inlet of vacuum pump and the oil outlet oil leab by oil pipe and diesel engine and the sump screw of draining the oil respectively are connected.
After adopting technique scheme, the utility model utilizes the lubricated vacuum pump of the circulation of the lubricating oil in the one-cylinder diesel engine housing, utilizes vacuum pump that vacuum cylinder is vacuumized again, for drg provides power.Simple in structure, safe and reliable, can improve the braking effect of single cylinder diesel effectively.
Description of drawings
Accompanying drawing is the structural representation of an embodiment of the present utility model.
The specific embodiment
As shown in drawings, single cylinder diesel three-wheel vehicle vacuum booster brake device described in the utility model, in the middle of diesel lubrication oil pipe 11, install a threeway 12 additional, and be connected with the oil inlet 6 of vacuum pump 10, the oil return pipe 5 of vacuum pump 10 is connected on the screw of draining the oil of sump, the aspirate tube 9 of vacuum pump is connected to vacuum barrel 8, and vacuum barrel 8 is communicated with servo-unit 2 again.
Diesel-engined drive vacuum pump 10 rotations during driving, provide lubricating oil by 6 pairs of vacuum pumps 10 of oil pipe simultaneously, lubricating oil is lubricated vacuum pump rotor and blade is provided radial pressure and the gap of rotor and stator is sealed, vacuum pump is vacuumized vacuum barrel 8 better, and vacuum barrel 8 just reaches certain degree of vacuum with A, the B chamber of servo-unit 2 like this; Chaufeur is when depressing brake pedal, brake push rod 1 moves to right, the piston that promotes servo-unit 2 the insides moves to right, thereby close the vacuum inlet in A chamber, open the atmospheric air port in A chamber simultaneously, A chamber and B chamber produce certain difference of pressure, promoting piston continues to move to right, the piston that push rod on the piston promotes brake pump 3 moves to right, and the pressure oil of generation flows to drg through oil main line 4, reaches the purpose of braking.Because push rod 1 promotes piston jointly with the difference of pressure that helps device A, B chamber and produces pressure oil, thus only need less treadle effort just can produce higher oil pressure, thus reach braking labour-saving purpose.
