Description
Technical Field
The utility model relates to the technical field of automobile retarders, in particular to a hydraulic retarder.
Background
The hydrodynamic retarder is an automobile retarder for reducing the running speed of a vehicle through a hydrodynamic device, and the hydrodynamic retarder utilizes liquid damping to generate retarding effect. The stator of the hydrodynamic retarder is a retarder shell, is connected with the rear end of the speed changer or the frame, the rotor is connected with the transmission shaft through the hollow shaft, and blades are cast on the rotor and the stator. In operation, pressure is applied to the oil sump by operation of the control valve to charge working fluid into the working chamber between the rotor and stator. When the rotor rotates, a torque is acted on the stator through the working fluid, and the counter torque of the stator becomes the braking torque of the rotor, wherein the value of the counter torque depends on the liquid amount and the pressure (depending on the braking strength gear set by the control valve) in the working cavity and the rotating speed of the rotor. The kinetic energy of the automobile is consumed by friction of the working fluid and impact on the stator to be converted into heat energy, so that the temperature of the working fluid is increased. The working fluid is introduced into the heat exchanger to circulate, transfer heat to the cooling water, and then is discharged through the engine cooling system.
At present, the working cavity, the oil storage tank and the heat exchanger of the existing hydrodynamic retarder are usually integrated together, so that the design has the advantage of compact structure, but the hydrodynamic retarder can have larger weight and volume after integration, so that higher requirements are provided for installation space, the stress influence on attached products (mainly a speed changer) is larger, higher requirements are provided for the strength of the attached products, and the manufacturing difficulty of parts is larger.
Disclosure of Invention
The utility model aims to solve the technical problem of providing the hydraulic retarder which has a simple structure and low requirements on installation space and attached products.
The technical scheme adopted for solving the technical problems is as follows:
the utility model provides a hydraulic retarder, includes oil storage tank, heat exchanger and has the host computer of working chamber, the oil storage tank with the heat exchanger set up the outside of host computer, the host computer have host computer oil inlet, host computer oil-out and lubricated hydraulic fluid port, the host computer oil-out with the oil inlet of heat exchanger pass through the pipeline and be connected, lubricated hydraulic fluid port with the oil return port of oil storage tank pass through the pipeline and link to each other, the oil-out of oil storage tank with the oil-out of heat exchanger link to each other the common end that forms pass through the pipeline with the host computer oil inlet link to each other.
The oil storage tank, the heat exchanger and the host are three independent parts. Different heat exchangers or oil storage tanks can be replaced according to specific use requirements, and the universality is good.
The oil storage tank and the heat exchanger are integrated into a single part. The installation process is reduced.
And a one-way valve is respectively arranged in the host oil inlet and the host oil outlet. Through set up a check valve respectively in host computer oil inlet and host computer oil-out, the check valve opens when hydraulic retarber work, makes the working medium can enter into the working chamber smoothly, and when hydraulic retarber is inoperative, through closing the check valve, realizes that the working medium can't enter into the working chamber to reduce the loss that idle running produced.
And an adjusting valve is arranged in the lubricating oil port. The function of the regulating valve is that when the pressure difference of the two connecting pipelines (or two connected cavities, namely the working cavity and the oil storage tank) at the front side and the rear side of the regulating valve reaches a set value, the regulating valve is closed in a bidirectional or unidirectional way, when the hydraulic retarder works, the working cavity generates pressure due to the fact that working medium flows at a high speed, the pressure difference is generated between the working cavity and the oil storage tank, the regulating valve is closed, when the hydraulic retarder does not work, the pressure generated by the working medium in the working cavity is reduced, the pressure difference between the working cavity and the oil storage tank is smaller than the set value, the regulating valve is opened, so that the working medium flows back into the oil storage tank, the working medium in the working cavity is further reduced, and loss during idling is reduced.
Compared with the prior art, the utility model has the advantages that: the oil storage tank and the heat exchanger are arranged outside the host machine to form a split structure, the split structure is connected with each other through the pipelines, the arrangement is simple, the requirements on the installation space and the structural strength of matched parts are low, the split structure is applied to automobiles, the stress condition of relevant parts of the automobiles can be improved, and the split structure is convenient for modularized production and manufacturing.
