Abstract

The invention discloses a hydraulic retarder for a heavy truck axle. The hydraulic retarder is characterized by comprising a gear pump (2); the oil inlet of the gear pump (2) is connected with an oil tank (1), while the oil outlet of the gear pump (2) is connected with a valve block; the valve block is composed of a pilot overflow valve (3) and a throttling valve (4), and is mounted on the oil tank (1); the oil outlet of the valve block is connected with a heat exchanger (5); the heat exchanger (5) is mounted on the oil tank (1) by use of a flange; according to the retarder, the structure of the original pair of gears on the main retarder of the middle axle is modified, and compared with a hydraulic speed reducer and an electrical vortex speed reducer, the hydraulic retarder has the advantages of simple and compact structure, low cost and easy control of braking power; compared with the traditional axle without the retarder, the retarder is used for assisting braking, so that the service life of a brake block and a tire can be remarkably prolonged and the safety of a vehicle can be improved.

Description

Technical field: [0001] The invention relates to the technical field of automobile axles and retarders, in particular to a hydraulic retarder for heavy truck axles. Background technique: [0002] At present, vehicle braking generally adopts water showers to cool down and brake, but the temperature of brake pads is high, and tire blowouts and tire spontaneous combustion occur from time to time, and water showers cannot solve the fundamental problem. The mainstream retarders on the market now mainly include eddy current retarders, hydraulic retarders, and permanent magnet retarders; these retarders are mainly installed behind the gearbox or the axle to increase the The bridge cantilever, and its complex structure has a great influence on the layout of the vehicle. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a hydraulic retarder for heavy truck bridges; mainly to solve the prob...
