Specific embodiment

With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this The protection scope of utility model is not limited by the specific implementation.

As shown in Figs 1-4, a kind of birotor retarder provided by the embodiment of the utility model, including rotor, shell 5, institute State be inside shell 5 transmission oil chamber resettling 3, the shell 5 closes by groove body 8 and lid at 9 groups of end cap of 8 side of groove body At, the end cap 9 seals the side for being fixed on groove body 8, so that shell 5 forms the transmission oil chamber resettling 3 of a sealing, it is described The side of shell 5 is equipped with pouring orifice 10, and pouring orifice 10 is equipped with sealing cover for injecting transmission oil, pouring orifice, and the end cap 9 is logical It crosses threaded connection and is fixed on 8 side of groove body, the two junction is sealed equipped with gasket.

The rotor includes transmission shaft 1 and impeller 2, and the transmission shaft 1 is located at the centre of gyration of the shell 5, laterally passes through Wear shell 5 and relative to 5 rotating support of shell, one end of the transmission shaft 1 is connect with driving engine, and the other end and axle pass Dynamic connection, the impeller 2 are located at the center in the chamber resettling 3 of the inside of shell 5 and being in shell 5, and the impeller 2 is solid It is scheduled on transmission shaft 1, the impeller 2 includes the first blade 22 of the impeller disk 21 and uniform array in the impeller disk 21, the shell The annular inner wall of body 5 is equipped with several second blades 4 corresponding with the first blade 22, first blade 22 and described second The size and shape of blade 4 matches, and first blade 22 and second blade 4 are on 3 circumferencial direction of chamber resettling Curved concave is towards on the contrary；

The utility model cooperates the brake system of vehicle to use, and the present apparatus is mounted on two braking brake blocks 11 by such as Fig. 4 Centre, braking brake block 11 links with the brake pedal of vehicle, and braking brake block 11 is separately mounted on the vehicle frame 12 of two sides, Shell 5 is fixed between two braking brake blocks 11, and the transmission shaft 1 of 5 two sides of shell is separately fixed on spring bearing 13, described Spring bearing 13 is fixed on vehicle frame 12, and one end of transmission shaft 1 is connect with engine mission, and the other end and rear driving axle connect It connecing, transmission oil is injected into the chamber resettling 3 of the transmission oil inside shell 5, transmission oil preferably selects the higher transmission oil of viscosity, 8# hydraulic transmission oil is selected, will be sealed at oiling, prevent transmission oil from revealing, when vehicle is run, the rotation of transmission shaft 1 is transported Row, transmission shaft 1 will drive the rotation of impeller 2, and the transmission oil that the first blade 22 on the impeller 2 can stir in chamber resettling 3 is same To rotation, due to the curved concave of the first blade 22 and second blade 4 on 3 circumferencial direction of chamber resettling towards on the contrary, While transmission oil rotates, it will drive shell 5 and rotate in same direction, so that birotor is formed, when needing to use retarder braking, operation Brake system makes brake block check shell 5, and shell 5 stops operating, and at the same time, the transmission oil inside shell 5 also will continue to turn It is dynamic, but since shell 5 stops operating, the second blade 4 on shell 5 can give transmission oil one reversed active force, transmission oil 22 1 oppositions of the first blade can be given again, while the first blade 22 can give transmission shaft 1 one oppositions, thus fast The revolving speed of prompt drop underneath drive axis 1, achievees the effect that retarder brake, and braking efficiency is higher, and original wheel braking is protected to fill It sets.The utility model structure is simple, and low cost, maintenance cost is also very low, and maintenance period is long, it is only necessary to replenish transmission oil or tune Whole replacement brake block can complete to safeguard, auxiliary braking is high-efficient, with transmission shaft without driving contact in normal vehicle operation, It links with brake pedal, brake response does not influence rapidly original brake and uses；It can successively be used according to brake pedal travel settings Retarder brake and wheel braking, it is convenient frequently to be used in different kinds of roads.It can also be assisted on various non-rice habitats driving vehicles Brake application, such as engineering machinery, farm machinery, train.

The junction of the shell 5 and transmission shaft 1 is equipped with bearing 6 to realize rotation branch of the transmission shaft 1 relative to shell 5 It holds, is relatively rotated between shell 5 and transmission shaft 1 to realize, axle envelope 7 is equipped at the bearing 6, prevents transmission oil in junction Leakage.

Disclosed above is only several specific embodiments of the utility model, and still, the utility model embodiment is not office It is limited to this, the changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
