Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0039]figure 1 , figure 2 It is a structural schematic diagram of the existing retarder, which has been described in the background technology of the specification.
[0040] Such as image 3 , Figure 4 A serial hydraulic retarder shown includes a retarder housing 1 and a heat exchanger housing 2 . The retarder housing 1 is provided with an air intake channel 131 by casting, which is used for connecting the air source to the oil pool 12 . see Figure 7 , The heat exchanger housing 2 is provided with a water inlet pipe 21 and a water outlet pipe 22 on the outer wall of the retarder housing 1, and the water inlet pipe 21 and the water outlet pipe 22 are arranged in a "character-eight" shape. see Figure 6 , the retarder housing 1 is provided with a through hole corresponding to the water inlet pipe 21 and the water outlet pipe 22, and the...

The invention relates to the technical field of automobile retarders, and provides a series hydrodynamic retarder. The series hydrodynamic retarder aims to solve the problems that according to an existing retarder, the overall structure size is large, the weight is high, the number of parts is large, and overhauls are troublesome with time and labor wasted. The series hydrodynamic retarder is characterized in that a water inlet pipe and a water outlet pipe are arranged on the part, opposite to a retarder shell, of the outer wall of a heat exchanger shell, the water inlet pipe and the water outlet pipe are arranged in the shape of inverted V, the retarder shell is provided with through holes corresponding to the water inlet pipe and the water outlet pipe correspondingly, and the diameters of the through holes are larger than the outer diameter of the water inlet pipe and the outer diameter of the water outlet pipe; and the water outlet pipe and the water inlet pipe which are arranged onthe heat exchanger shell in the shape of inverted V extend into the corresponding through holes of the retarder shell, and are arranged to encircle the retarder shell. Because the heat exchanger shell is arranged in a different mode, the axial installation distance of the retarder is effectively shortened, and the axial dimension of the retarder is effectively shortened; and the overall axial distance of the retarder which increases originally because of the height of the water pipes decreases.
Description
technical field [0001] The invention relates to the technical field of automobile retarders, in particular to a serial hydraulic retarder. Background technique [0002] As one of the most important auxiliary braking devices of the whole vehicle, the hydraulic retarder has completely replaced the electric eddy current retarder in Europe due to its advantages of fuel saving, light weight, high braking efficiency and no thermal fading. In the early stage of hydraulic retarder in my country, it was limited to some colleges and universities and research institutes for theoretical research, and the research and development of physical objects was progressing slowly. [0003] The existing series hydraulic retarder usually includes the retarder casing, the retarder stator, the retarder rotor, the solenoid valve assembly, the output flange and the heat exchanger assembly. Provide space; the retarder stator is fixed on the retarder casing, and the blade direction is opposite to that ...
