Abstract
The invention relates to a hydrodynamic retarder. The transmission shaft of the hydrodynamic retarder is in transmission connection with the shaft of a hydraulic pump through a clutch; the shaft of the hydraulic pump is in transmission connection with the working shaft of a hydraulic motor; the high-pressure oil pipe of the hydraulic pump connected with the oil inlet of the hydraulic motor; and when high-pressure oil is input through the oil inlet, the hydraulic motor can generate a counter acting force relative to the transmission direction of a transmission system. The hydrodynamic retarder is designed according to the working principles of the hydraulic pump and the hydraulic motor; and the hydraulic pump and the hydraulic motor are assembled together and connected through the shafts. During use, the hydraulic pump of the hydrodynamic retarder is driven to generate high-pressure oil by virtue of the kinetic energy of the transmission system, high-pressure oil enters the oil inlet of the hydraulic motor and then drives the hydraulic motor to generate a counter acting force relative to the transmission direction of the transmission system to achieve the purpose of deceleration; and no abrasion is caused to other systems. The hydrodynamic retarder has the advantages of no energy consumption, zero contamination, simple structure and good braking effect, and is applicable to various wheeled rolling equipment, including trains and airplanes, particularly braking systems in the automobile industry.
Description
Technical field
The present invention relates to a kind of brake equipment, is a kind of hydrodynamic retarder specifically.
Background technology
Vehicle can produce powerful propelling thrust when descending, causes braking quality to reduce and even loses efficacy, thus accidents causedly to cause casualties and property damage.For improving this present situation, what current automotive market used has two kinds of retarders, and a kind of is produce damping with hydraulic oil at turbine room the kinetic transformation of change speed gear box is slowed down for thermal energy consumption falls into row, and this theoretical retarder produced, reaction is slow, weak effect.At inoperative motoring condition, consumption of engine transmitted power 4%, complex structure, productive costs and service expenditure high.Another kind is current vortex retarder, utilizes transmission shaft cutting magnetic line to produce drag braking.At off working state consumption of engine transmitted power 1%, self is heavy, and inconvenience is installed, temperatures as high 650 DEG C during work, easy scaling loss equipment, and there is disaster hidden-trouble.
Summary of the invention
The object of the present invention is to provide a kind of Non-energy-consumption, pollution-free, structure is simple, the hydrodynamic retarder of good braking effect.
Technical scheme of the present invention comprises a transmission shaft, and transmission shaft is connected with the shaft drive of Hydraulic Pump through power-transfer clutch, and the axle of Hydraulic Pump and the working shaft of HM Hydraulic Motor are in transmission connection; The oil inlet that high pressure fuel pipe and the transmission direction of the relative driving system of energy when inputting high pressure oil of Hydraulic Pump produce the HM Hydraulic Motor of antagonistic force is connected.
The high pressure fuel pipe of described Hydraulic Pump is equipped with pressure-gradient control valve.
Described transmission shaft is gear wheel shaft.
The axle of described Hydraulic Pump is gear wheel shaft.
The present invention utilizes the principle of work of Hydraulic Pump and HM Hydraulic Motor to design, and Hydraulic Pump and HM Hydraulic Motor is fitted together, and is connected by axle (can be gear wheel shaft).In use, utilize the kinetic energy of driving system, drive Hydraulic Pump of the present invention to produce high pressure oil, after high pressure oil enters HM Hydraulic Motor oil inlet, drive the transmission direction of the relative driving system of HM Hydraulic Motor to produce antagonistic force, reach deceleration object, and to other system without wearing and tearing.
Compared with prior art, the present invention has Non-energy-consumption, pollution-free, and structure is simple, the advantages such as good braking effect.Be applicable to various wheeled rolling equipment, comprise the brake system of train, aircraft, particularly auto trade.
Accompanying drawing explanation
The embodiment provided below in conjunction with accompanying drawing is described in further detail.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
In Fig. 1, the present invention is in transmission connection through the power input shaft 2 of transmission shaft 4 and gearbox body 3 and output shaft 1, and transmission shaft 4 is in transmission connection through the axle 6 of power-transfer clutch 5 with Hydraulic Pump, and the axle 6 of Hydraulic Pump is in transmission connection with the working shaft 13 of HM Hydraulic Motor 12; The HM Hydraulic Motor oil inlet 11 that the high pressure oil that Hydraulic Pump 7 produces produces antagonistic force through high pressure fuel pipe 10 and the transmission direction of the relative driving system of the energy of the HM Hydraulic Motor 12 when inputting high pressure oil is connected, and between the high pressure fuel pipe 10 of Hydraulic Pump 7 and HM Hydraulic Motor oil inlet 11, pressure-gradient control valve 9 is housed.Pressure-gradient control valve 9 is connected with hydraulic reservoir 8.The axle 6 of transmission shaft 4 and Hydraulic Pump is gear wheel shaft.
Hydraulic Pump and HM Hydraulic Motor belong to known technology, and tectonic sieving and principle of work no longer illustrate at this.
When 1, using on automobile, the present invention is assemblied on change speed gear box, there is arrangement of clutch centre, when automobile needs to slow down, by the pneumatic or electric device be connected with brake system, also can manual mode operation, meshing power-transfer clutch of the present invention, Hydraulic Pump of the present invention is started working, the hydraulic oil of hydraulic reservoir produces high pressure oil through Hydraulic Pump, produce antagonistic force by high-pressure oil duct and pressure-gradient control valve rear drive HM Hydraulic Motor relative to the hand of rotation of gear wheel shaft, the resistance of generation is delivered to change speed gear box by gear wheel shaft, thus reaches the object of deceleration.Pressure-gradient control valve can control pressure and the delivery quality of high pressure oil, thus the Resistance Value that hydraulic control motor produces, make automobile at desirable speeds, traffic safety can be ensured to greatest extent.
When 2, using aboard, can install an output shaft additional on the wheel of train, drive the present invention, arrangement of clutch is equipped with in centre, allows power-transfer clutch meshing the present invention when needing, and the present invention starts working, and reaches the object of deceleration or assist brake.
When 3, using aboard, on the steel ring of wheel, assembling drives driving device of the present invention, and when aircraft tyre lands and rotates, drive the present invention to start working, second-mission aircraft slows down and stops.
Implementation method can setting position be different according to the structure of the equipment of use is different, and Hydraulic Pump and HM Hydraulic Motor can select different size and model as required.
