Abstract
The present invention relates to the drg that a kind of liquid activates, the main hydraulic efficiency pressure system of forming by Hydraulic Pump, hydraulic braking cylinder, liquid case, the friction parts that hydraulic braking cylinder drives and the wheel shaft of motor-car constitute the driving device of Hydraulic Pump.The road vehicle that is suitable for most long and big train and band trailer uses, and also can be used on other vehicle the braking of can stopping, emergency situation braking and speed governing braking., the saving energy accurately rapider, safe and reliable than existing brake equipment.
Description
The present invention relates to a kind of drg of fluid-actuated.Be mainly used in the braking of rail vehicle, also can be in the braking of the power actuated vehicle of rail that is used for other or rail.
The rolling stock braking is ad initio so far based on the friction braking, on the modern train, particularly high-speed train has mostly installed dynamic brake additional, can only use as auxiliary braking but the speed of a motor vehicle can not be braked zero because of it, though the braking energy that the friction braking is born is little, must use.Representative type friction braking activates its friction member (brake shoe or disc type brake member) with pressurized air, the newer Japan's 951 types test hydraulic brake system that is stated from " railway braking technology in modern age " has adopted the liquid actuating, its hydraulic brake unit, have oil pump, fuel tank, oil hydraulic braking cylinder and each pipeline, valve, switch etc., wherein oil pump is with motor-driven, needs the additive decrementation energy at glancing impact.
The objective of the invention is to disclose and a kind ofly brake the hydraulic brake system of motor-car, need not add the energy in addition with the existing kinetic energy of motor-car itself.
A kind of hydraulic brake of vehicle has the friction parts that Hydraulic Pump, liquid case, hydraulic braking cylinder, pipeline, valve, hydraulic braking cylinder promote, and it is characterized in that being provided with driving device between the wheel shaft of motor-car and the Hydraulic Pump.
Driving device is in when state, motor-car is not normally braked, and is in when closing state, and the rotation energy of axletree drives hydraulic pump works by driving device, highly pressurised liquid is pressed into hydraulic braking cylinder by check valve, drives friction part (brake shoe, wheel or disk) contact and the friction braking.The present invention is the energy with the kinetic energy of vehicle, without additionaling power, save the energy, equipment is simpler than the compression Pneumatic brake systems, fast to the speed-slackening signal reflection, braking accurately, and is safe and reliable, because of it does not drive with engine installation, and be the energy with axle kinetic energy, not only should be contained in power car, and should be contained in, so the road vehicle of long, big train of its optimum and band trailer uses by on the motor vehicle.
Further specify by embodiment below in conjunction with accompanying drawing.
Description of drawings:
Fig. 1 is a hydraulic scheme of the present invention;
Fig. 2 is the scheme of installation of the present invention on vehicle.
Embodiment is the hydraulic brake on the rolling stock, working medium is an oil, consulting Fig. 2 Hydraulic Pump 1 is contained in by the spindle nose, it is a pluger type hydraulic pump, pump is by pump chamber 2, piston 3 and stage clip 4 constitute, driving device is made of with a drive block 6 that contacts with the piston outer end the cam 5 that is contained on the axle, for on the loss drive block that reduces friction pulley 7 being housed, consult the feed tube 9 of Fig. 1 Hydraulic Pump connecting band check valve 8 and the drain pipe 11 of band check valve 10, drain pipe 11 is divided into two arms 13 and 14 again, arm 13 leads to hydraulic braking cylinder 15, brake cylinder passes through lever, promote 16 work of friction parts, and arm 14 connects liquid case 18 by automatically controlled adjustable throttling 12, feed tube 9, connect liquid case 18 by filter 17, in order to reduce the wearing and tearing of Hydraulic Pump, an if electric control clutch, in normal operation, do not need glancing impact that piston is locked in the darkest position, itself and driving device are disengaged, remove emergency braking, the speed governing braking is outside the braking of stopping, humping, flat shunting braking is common on railway, and glancing impact is often mixed again with taking off and colluded operation, colludes operation and becomes safe (stubborn valve) and operate as long as install additional can will adventurously take off easily once cover valve 19 and cleaner hydraulic actuating cylinder 20 on hydraulic efficiency pressure system.
The utility model is that the mechanical energy of motor-car itself is not done transformation of energy, and directly drive friction parts abrupt deceleration vehicle by driving device, because it is the ancient friction brake efficiency height of power driven friction brake percentage (stopping distance weak point), economize the energy compared with available dynamic system, the complex apparatus and the energy consumption of transformation of energy have been saved compared with regenerative brake, as long as the appropriate adhesion factor of handling between the wheel track, just can be used for the braking of high-speed train, this brake uses the adjusting of 12 pairs of liquid outlet quantity of automatically controlled adjustable throttling, not only can be used as stopping brake or not brake (alleviation), and can do the speed governing braking, the speed of a motor vehicle is aligned to certain speed.
