Abstract
The utility model relates to a hydrodynamic retarder. A transmission shaft of the hydrodynamic retarder is in transmission connection with a shaft of a hydraulic pump through a clutch, the shaft of the hydraulic pump is in transmission connection with a working shaft of a hydraulic motor, and a high-pressure oil pipe of the hydraulic pump is connected with an oil inlet of the hydraulic motor which can produce counter-acting force relative to a transmission direction of a transmission system when high-pressure oil is input. The hydrodynamic retarder is designed according to working principles of the hydraulic pump and the hydraulic motor, and the hydraulic pump and the hydraulic motor are assembled together and are connected through a shaft. When the hydrodynamic retarder is used, by means of kinetic energy of the transmission system, the hydraulic pump is driven to produce the high-pressure oil, after the high-pressure oil enters the oil inlet of the hydraulic motor, the hydraulic motor is driven to produce the counter-acting force relative to the transmission direction of the transmission system, the purpose of speed reduction is achieved, and other systems are not abraded. The hydrodynamic retarder is free of energy consumption and pollution, simple in structure, good in brake effect and capable of being used in various wheel-type rolling equipment including trains and planes, especially the brake system of the automobile industry.
Description
Technical field
The utility model relates to a kind of brake equipment, is a kind of hydrodynamic retarder specifically.
Background technology
Vehicle can produce powerful propelling thrust when descending, cause braking quality to reduce even inefficacy, thus accidents caused causing casualties and property damage.For improving this present situation, automotive market uses at present two kinds of retarders, and a kind of is to produce the kinetic transformation that damping makes change speed gear box take hydraulic oil at turbine room to slow down as thermal energy consumption falls into row, this theoretical retarder of producing, and reaction is slow, weak effect.At the inoperative motoring condition, consumption of engine transmitted power 4%, complex structure, productive costs and service expenditure are high.Another kind is current vortex retarder, utilizes the transmission shaft cutting magnetic line to produce drag braking.At off working state consumption of engine transmitted power 1%, self heaviness, inconvenience is installed, during work temperature up to 650 ℃, easy scaling loss equipment, and have disaster hidden-trouble.
Summary of the invention
The purpose of this utility model is to provide a kind of Non-energy-consumption, and is pollution-free, simple in structure, the hydrodynamic retarder of good braking effect.
The technical solution of the utility model 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 high pressure fuel pipe of Hydraulic Pump is connected with the oil inlet that the transmission direction of the relative driving system of energy when inputting high pressure oil produces the HM Hydraulic Motor of antagonistic force.
On the high pressure fuel pipe of described Hydraulic Pump pressure-gradient control valve is housed.
Described transmission shaft is gear wheel shaft.
The axle of described Hydraulic Pump is gear wheel shaft.
The utility model utilizes the principle of work of Hydraulic Pump and HM Hydraulic Motor to design, and Hydraulic Pump and HM Hydraulic Motor are fitted together, and is linked to each other by axle (can be gear wheel shaft).In use, utilize the kinetic energy of driving system, drive Hydraulic Pump of the present utility model and produce high pressure oil, after high pressure oil enters the HM Hydraulic Motor oil inlet, the transmission direction that drives the relative driving system of HM Hydraulic Motor produces antagonistic force, reaches the deceleration purpose, and to other system without wearing and tearing.
Compared with prior art, the utlity model has Non-energy-consumption, pollution-free, simple in structure, the advantages such as good braking effect.Applicable to various wheeled rolling equipments, comprise the brake system of train, aircraft, particularly auto trade.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing is described in further detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Among Fig. 1, the utility model is in transmission connection through power input shaft 2 and the output shaft 1 of transmission shaft 4 with gearbox body 3, 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 high pressure oil that Hydraulic Pump 7 produces is connected with the HM Hydraulic Motor oil inlet 11 that the transmission direction of the relative driving system of 12 energy of HM Hydraulic Motor when inputting high pressure oil produces antagonistic force through high pressure fuel pipe 10, between the high pressure fuel pipe 10 of Hydraulic Pump 7 and the 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 structure design and principle of work no longer illustrate at this.
1, when automobile uses, the utility model is assemblied on the change speed gear box, there is arrangement of clutch the centre, when automobile need to slow down, by the pneumatic or electric device that links with brake system, also can manual mode operation, meshing power-transfer clutch of the present utility model, Hydraulic Pump of the present utility model 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 with respect to the hand of rotation of gear wheel shaft, the resistance of generation is delivered to change speed gear box by gear wheel shaft, thereby reaches the purpose of deceleration.Pressure-gradient control valve can be controlled pressure and the delivery quality of high pressure oil, thereby the Resistance Value that the control HM Hydraulic Motor produces can travel in desirable speed automobile, guarantees to greatest extent traffic safety.
When 2, using aboard, can install at the wheel of train an output shaft additional, drive the utility model, arrangement of clutch is equipped with in the centre, allows the meshing the utility model of power-transfer clutch when needing, and the utility model is started working, and reaches to slow down or the purpose of assist brake.
When 3, using aboard, on the steel ring of wheel, assembling drives driving device of the present utility model, when aircraft tyre lands rotation, drives the utility model and starts working, and second-mission aircraft slows down and stops.
Implementation method can be according to the structure difference of using equipment and setting position is different, and Hydraulic Pump and HM Hydraulic Motor can be selected different size and model as required.
