Abstract
The present invention relates to a brake with liquid brake. The brake is mainly composed of a hydraulic system, a friction component and a drive device of a wheel shaft of a motor car, wherein the hydraulic system is composed of a hydraulic pump, a hydraulic brake cylinder and a fluid box; the friction component is driven by the hydraulic brake cylinder; the drive device is used for the hydraulic pump. The present invention is suitable for long and large trains and road vehicles with scoops, and the present invention can be used for other vehicles to brake in station stop, in emergency situations and in speed regulation. Compared with the existing brake device, the present invention has the advantages of accuracy, rapidity, safety, reliability and energy saving.
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 used for the braking of the power actuated vehicle of other rail or trackless.
The rolling stock braking is ad initio so far based on 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 friction braking is born is little, must use.The 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, friction means with Hydraulic Pump, liquid case, hydraulic braking cylinder, pipeline, valve, hydraulic braking cylinder promotion, it is characterized in that being provided with driving device between the wheel shaft of motor-car and the Hydraulic Pump, Hydraulic Pump is the electric control clutch pump, which is provided with electric control clutch.
When driving device is in released state, the normal operation of motor-car is not braked, and when being in closure state, 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 member (brake shoe, wheel or disk) contact and 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 reaction, 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 pulley 7 is housed on the drive block that reduces friction loss, 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 friction means 16 work, 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, stop the braking outside, humping, the flat shunting braking is common on railway, glancing impact is often followed the operation of breaking off relations again, just can easily adventurous unhook operation be become safe (twisting valve) and operates as long as add a suit valve 19 and lancet hydraulic actuating cylinder 20 on hydraulic efficiency pressure system.
The utility model is that the mechanical energy of motor-car itself is not done the energy conversion, and directly drive friction parts abrupt deceleration vehicle by transmission device, because it is friction catch under the power drive, than ancient friction catch efficient height (braking distance is short), economize the energy compared with existing dynamic braking, complex apparatus and the energy consumption of energy conversion have been saved compared with regenerative braking, as long as the appropriate adhesion coefficient of processing between the wheel track, just can be used for the braking of high-speed train, this brake utilizes 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.
Claims (2)
1, a kind of hydraulic brake of vehicle, friction means with Hydraulic Pump, liquid case, hydraulic braking cylinder, pipeline and valve, hydraulic braking cylinder promotion, it is characterized in that being provided with driving device between the wheel shaft of motor-car and the Hydraulic Pump, Hydraulic Pump is the electric control clutch pump, which is provided with electric control clutch.
2, brake according to claim 1 is characterized in that an arm 14 of hydraulic pressure drain pipe connects the liquid case by automatically controlled adjustable throttling 12.
