Embodiment Construction
[0026] The front retarder of the case with a wet clutch includes a front housing 8, a retarder housing 4, a hydraulic retarder, a wet clutch, a clutch housing 17, a bearing seat 19, and an output shaft 21.
[0027] The fixed wheel 5 of the retarder in the front retarder with a wet clutch is a ring structure, and there are inclined blades on the ring wall; the moving wheel 6 of the retarder is a disc structure, which corresponds to the blade position of the fixed wheel 5 Inclined vanes; two sets of vanes form an oil circulation channel, and the retarder moving wheel 6 is connected with the front housing 8 through splines.
[0028] There are two cavities in the retarder housing 4 in the front retarder with wet clutch, one part is used to fix the fixed wheel 5 of the retarder; the other part is used to place the moving wheel 6 of the retarder; The casing 4 is also provided with a through-hole oil channel 29 for oil circulation; the through-hole oil channel communicates with the o...

The invention relates to a gearbox-front retarder with a wet type clutch. The gearbox-front retarder with the wet type clutch comprises an input shaft, a hydraulic retarder, the wet type clutch and an output shaft, wherein the hydraulic retarder comprises a housing, a control valve, a through hole oil channel, a fixed wheel and a movable wheel; two cavities are arranged in the housing of the retarder, one cavity is used for fixedly mounting the fixed wheel of the retarder, and another cavity is used for storing the movable wheel of the retarder; two blades of the fixed wheel and the movable wheel of the retarder form an oil flowing channel. The gearbox-front retarder with the wet type clutch is simple in structure, and high in braking safety, and is provided with an individual type hydraulic control system; the retarder is mounted between an engine and a gearbox and used for assisting braking; the technical problems of complex structure, high sealing requirements and inconvenient product repair and replacement due to the existing integrated design of the wet type clutch and the gearbox can be solved; the running safety of a heavy vehicle can be improved.
Description
technical field [0001] The invention relates to a front retarder with a wet clutch, which is mainly used in medium and heavy vehicles. Background technique [0002] With the development of vehicles towards high speed and heavy load, relying solely on traditional mechanical friction brakes can no longer meet people's requirements for vehicle safety and comfort, especially in mountainous areas (large-tonnage trucks and large passenger cars). In order to limit the speed of the vehicle when going downhill, it is necessary to ensure continuous braking for a long time, so that the brake shoes are frequently tapped on long and large slopes, causing the brake shoes to heat up, the friction coefficient is reduced, the braking load is too large, and the so-called brake failure occurs. The thermal decay phenomenon of braking efficiency seriously affects the driving safety of automobiles. Domestic tractors mainly water the brake pads when going downhill, and the braking effect is not v...
