Abstract

The invention belongs to the technical field of retarders, and discloses a hydrodynamic retarder rotor. The hydrodynamic retarder rotor comprises a rotor disc and a plurality of blades, and the rotor disc comprises a disc body and a middle shaft connected to the disc body; the blades are evenly distributed around the circumference of the middle shaft, each blade comprises a fixed piece part and a rotating piece part, the fixed piece parts are fixedly connected to the disc body and extend in the radial direction of the disc body, the rotating piece parts are rotationally arranged on the disc body, the blades have a working state and a loss reduction state, in the working state, the rotating piece parts and the fixed piece parts abut against each other and are coplanar, and in the loss reduction state, an included angle is formed between each rotating piece part and the corresponding fixed piece part. In the working state, the fixed piece parts and the rotating piece parts form the unfolded blades, at the moment, the acting area of pressure oil on the blades reaches the maximum, and large braking torque is generated on the blades; and when no-load occurs, the blades are adjusted to be in the loss reduction state, the included angle is formed between each rotating piece part and the corresponding fixed piece part, the bent blades are formed, the acting area of pressure oil on the blades is reduced, and therefore the effect of reducing no-load losses is achieved.

Description

technical field [0001] The invention belongs to the technical field of retarders, in particular to a hydraulic retarder rotor. Background technique [0002] The hydraulic retarder is a device that uses liquid damping to produce a retarding effect. Its main working principle is that the rotation of the rotor drives the rotation of the pressure oil, thereby acting a torque on the stator, and the counter torque of the stator becomes the braking torque of the rotor. [0003] At present, the brake torque is adjusted by adjusting the liquid filling amount (the ratio of oil and air content inside the hydraulic retarder). The size of the torque, one is electric drive to control the opening of the oil inlet channel to adjust the braking torque, so as to achieve the purpose of adjusting the braking torque of the hydraulic retarder according to the road conditions. Load loss, but the effect is not good, usually need to add additional loss reduction device, making the structure comple...
