Description
Technical field
The present invention relates to hydraulic machine technical field, be specifically related to a kind of hydraulic retarder determined for vehicle auxiliary braking.
Background technology
Hydraulic retarder is a kind of by device less for the abrasion that changes mechanical energy is liquid heat energy, especially for braking vehicle or other equipment.Two i.e. primary runner driven of opposed impeller and a relatively neighbour layout of fixing or rotating secondary impeller, thus forming a circular working chamber, in this working chamber, working media forms flow circuits.Primary runner drives working solution to rotate about the axis；Meanwhile, working solution moves along direction blade, gets rid of to secondary impeller.Working solution is produced retroaction by secondary impeller, and working solution outflow secondary impeller goes back to again impacts primary runner, thus forms the moment of resistance to primary runner, hinders the rotation of primary runner, thus realizing the retarding braking effect to vehicle.When working solution flows between impeller, temperature raises, and hot operation liquid enters back into hydraulic retarder after guiding by the road and lowering the temperature, thus realizing continuous operation.
The commonly used engine coolant of current hydraulic retarder comes to the mode of hydraulic retarder working solution cooling, the problem of the program is to affect the thermal balance of electromotor, engine cool liquid pipeline is oversize and complicated, easy seepage even results in electromotor cisco unity malfunction, install and safeguard complexity, high in cost of production.
Summary of the invention
For there being the defect of technology on overcoming, a kind of hydraulic retarder is provided, the hydraulic retarder that working media is oil especially for vehicle auxiliary braking, make it have independent cooling system, this cooling system with controlled fan to regulate heat-sinking capability, it is ensured that hydraulic retarder is operated in stronger temperature range.
For achieving the above object, the present invention adopts such as purgation technical scheme:
A kind of hydraulic retarder, including working chamber, oil storage pool, cooling mechanism and power transmission shaft, described power transmission shaft runs through described working chamber, described working chamber is provided with working solution entrance point and the working solution port of export, wherein working solution entrance point is connected with oil storage pool by oil circuit, the working solution port of export is connected with cooling mechanism entrance by oil circuit, and cooling mechanism outlet is connected with oil storage pool by oil circuit；Described oil storage pool is provided with compressed air inlet.
Further, described working chamber is made up of primary runner and secondary impeller, and primary runner is around drive axis, and secondary impeller is connected with oil circuit.
Further, cooling mechanism includes housing, is positioned on housing and is provided with inlet and liquid outlet, is provided with fin in the described housing between inlet and liquid outlet.
Further, described fin is provided above fan, and described fan is fixed on housing.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
A kind of hydraulic retarder provided by the invention, after power transmission shaft is slowed down by working chamber, the heat of its generation can be transferred to outside by cooling mechanism, lower the temperature to hydraulic retarder working solution without adopting engine coolant, thus solving Engine Heat Balance problem, reducing and installing and maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of hydraulic retarder of the present invention.
In figure: 1. power transmission shaft；2. primary runner；3. secondary impeller；4. oil circuit；5. cooling mechanism；6. oil storage pool；7. compressed air inlet.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment:
As shown in Figure 1: a kind of hydraulic retarder, including working chamber, oil storage pool 6, cooling mechanism 5 and power transmission shaft 1, described power transmission shaft 1 runs through described working chamber, described working chamber is provided with working solution entrance point and the working solution port of export, wherein working solution entrance point is connected with oil storage pool 6 by oil circuit 4, the working solution port of export is connected with cooling mechanism 5 entrance by oil circuit 4, and cooling mechanism 5 is exported and is connected with oil storage pool 6 by oil circuit；Described oil storage pool 6 is provided with compressed air inlet 7.Specifically, described working chamber is made up of primary runner 2 and secondary impeller 3, and primary runner 2 rotates around power transmission shaft 1, and secondary impeller 3 is connected with oil circuit 4.Described cooling mechanism 5 includes housing, it is positioned on housing and is provided with inlet and liquid outlet, in the described housing between inlet and liquid outlet, be provided with fin, in order to accelerate fin heat radiation, can just arranging fan on a heat sink, this fan is fixed on housing.Its fan can select controllable fan.
During hydraulic retarder work, the compression compressed air intlet 7 of air enters oil storage pool 6, and the working solution in oil storage pool 6 is pressed into the working chamber formed by primary runner and secondary impeller through oil circuit 4, and hydraulic retarder is started working.Primary runner 2 drives working solution to rotate about the axis；Meanwhile, working solution moves along the direction blade of primary runner 2, gets rid of to secondary impeller 3.Working solution is produced retroaction by the blade of secondary impeller 3, and working solution outflow secondary impeller 3 goes back to again impacts primary runner 2, thus forms the moment of resistance to primary runner 2, hinders the rotation of primary runner 2, thus realizing the decelerating effect to vehicle.Working solution makes import and export form pressure differential in working chamber in motor process, working solution circulates, and during by cooling mechanism 5, heat is taken away by air.When hydraulic retarder quits work, the compression compressed air intlet 7 of air is discharged, working solution in oil storage pool 6 does not enter back into hydraulic retarder working chamber, and the working solution in working chamber rotates with primary runner 2 and produce the effect of centrifugal force and flow back to oil storage pool 6 through oil circuit 4 and cooling mechanism 5 under centrifugal action, no longer produce braking torque after the emptying of working solution in hydraulic retarder working chamber.
Technical solution of the present invention provides a kind of hydraulic retarder, after power transmission shaft is slowed down by working chamber, the heat of its generation can be transferred to outside by cooling mechanism, lower the temperature to hydraulic retarder working solution without adopting engine coolant, thus solving Engine Heat Balance problem, reducing and installing and maintenance cost.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalences done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
