Abstract
A tractor hydraulic brake-operating device essentially comprises a brake pump, an oil tank, an oil tube, and a booster hydro-cylinder. The brake pump essentially comprises a brake pump casing, a brake pump piston, a piston returning spring, the oil tank, a check-valve, a balanced valve, a throttle valve, an oil seal pedal, a pedal, and an adjusting screw. The booster hydro-cylinder essentially comprises a brake hydro-cylinder casing, a brake hydro-cylinder piston, a piston rod, an O-shaped ring, and an air-bleed screw. When in braking, a brake pedal is stepped down to close the check-valve, and the oil pressure is set up, the pressed oil flows through the oil tube to enter a brake hydro-cylinder for pushing the piston, then the piston rod is for pushing a brake swinging arm, the power for braking is produced to loose the brake pedal, finally, the pedal is returned under the spring force. The brake oil-pressure is produced by the tractor driver to step down the pedal of the brake pump in the driving cabin, thereby the purpose of brake operation is achieved.
Description
(1) technical field
The utility model belongs to the trac. field, relates to a kind of used with tractor fluid pressure type brake control device.
(2) background technology
At present, domestic high and medium power wheel-tire tractor drg generally adopts mechanical control and mechanical compaction, perhaps hydrostatic manipulation and hydrostatic compressing.The shortcoming of these two kinds of brake operation modes is: the drg driving efficiency of mechanical control and mechanical compaction is lower, the lever piece member difficult arrangement; Hydrostatic manipulation and the hydrostatic drg that compresses also need to be provided with in addition Parking Brake.
(3) summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, use reliable, control comfort labour-saving used with tractor fluid pressure type brake control device.
The technical solution of the utility model is: tractor hydraulic formula brake control device mainly comprises brake pump 10, fuel tank 1, oil pipe 18,19, power-assisted oil cylinder 17.Fuel tank 1 is installed in the top of brake pump 10 by oil pipe 19, and power-assisted oil cylinder 17 links to each other with brake pump 10 by oil pipe 18.
The utility model can reach following beneficial effect: because used with tractor fluid pressure type brake control device adopts brake pump to set up oil pressure, promote the brake cylinder piston, the brake pump oad is little, can be arranged in the bridge instrumentation cover easily; Brake cylinder is arranged on the drg, can arrange oil pipe easily from the brake pump to the brake cylinder, and compact conformation is handled reliable.Compare with the market like product, this device driving efficiency height is handled laborsavingly, satisfies braking requirement better.
(4) description of drawings
Fig. 1 is the main TV structure cutaway view of the utility model used with tractor fluid pressure type brake control device.
(5) specific embodiment
Fluid pressure type brake control device shown in Figure 1 mainly is made up of brake pump 10, fuel tank 1, oil pipe 18,19, power-assisted oil cylinder 17 etc.Wherein brake pump mainly is made up of brake pump housing 5, brake pump piston 7, piston return spring 8, boiler check valve 3, balance cock 4, flow regulating valve 2, oil sealing 6, pedal 11, adjustment of pedals screw 9.The power-assisted oil cylinder mainly is made up of brake cylinder housing 16, brake cylinder piston 15, piston rod 12, O shape circle 13, air bleed screw 14.Brake pump piston 7 and oil sealing 6 are contained in the brake pump housing 5, and piston return spring 8 is contained in the brake pump piston 7, and boiler check valve 3 and balance cock 4 are contained on the brake pump housing 5, and pedal 11 and adjustment of pedals screw 9 are contained on the brake pump housing 5.Power-assisted oil cylinder 17 comprises brake cylinder housing 16, brake cylinder piston 15, piston rod 12, O shape circle 13, air bleed screw 14, brake cylinder piston 15 and piston rod 12 are contained in the brake cylinder housing 16, piston rod 12 bulbs withstand the ball-and-socket of brake cylinder piston 15, O shape circle 13 is contained on the brake cylinder piston 15, and air bleed screw 14 is contained on the brake cylinder housing 16.
Glancing impact is stepped on brake pedal 11, and oil pressure is set up in boiler check valve 3 sealings, and pressure oil enters power-assisted oil cylinder 17 by flow regulating valve 2 through oil pipe 18, promotes piston 15, and piston rod 12 promotes the drg rocking arm, produces braking force.When unclamping pedal 11, flow regulating valve 2 guarantees to move on pedal 11 slowly.Operator on the tractor can produce braking oil pressure by step on brake pump pedal 11 in operator's compartment.
