A hydraulic retarder with axial liquid inlet and tangential liquid discharge

Abstract

The invention discloses an axial-liquid-feeding and tangent-liquid-discharging hydrodynamic retarder. The axial-liquid-feeding and tangent-liquid-discharging hydrodynamic retarder consists of a rotor, a stator and a shell, wherein the rotor consists of a transmission shaft and an impeller; the impeller is provided a spoke disc hub, first rotor blades and second rotor blades; the first rotor blades and the second rotor blades are uniformly arranged around the periphery of the transmission shaft and form an acute angle with the radial direction of the spoke disc hub; the first rotor blades are located on one side of a disc surface of a spoke disc, and the second rotor blades are located on the other side of the disc surface of the spoke disc; the stator consists of bearing end cover blades and liquid-feeding end cover blades; the bearing end cover blades and the liquid-feeding end cover blades are uniformly arranged around the periphery of an annual working cavity and form an acute angle with the radial direction; the bearing end cover blades are fixed on axial positions, which right face to the first rotor blades, of a bearing end cover; and the liquid-feeding end cover blades are fixed on axial positions, which right face to the second rotor blades, of a liquid-feeding end cover; and the oblique directions of the rotor blades and the stator blades are opposite to each other in the radial direction. By adopting the axial-liquid-feeding and tangent-liquid-discharging hydrodynamic retarder, retarding and braking performance and effect are improved, and meanwhile, the axial-liquid-feeding and tangent-liquid-discharging hydrodynamic retarder has better manufacturability.

Description

technical field [0001] The invention relates to a hydraulic retarder, in particular to a hydraulic retarder used in a vehicle retarder braking system. This retarder uses fluid as the working medium, and changes the flow velocity and direction of the fluid rapidly The resulting energy dissipation effect forms a braking effect. The hydraulic retarder of the present invention can also be directly used as the load of test equipment such as a transmission system test device and a power test device. Background technique [0002] With the development of my country's economy, the increasing demand for passenger and cargo transportation, and the growth of the total road mileage, road transportation accidents are also showing an upward trend. Among them, commercial vehicles, especially freight vehicles, have frequent serious traffic accidents caused by brake failure. caused severe loss of life and property. When a commercial vehicle is driving, it is necessary to control the speed of...

Problems solved by technology

However, because the structure of the hydraulic retarder is similar to that of the hydraulic transmission, the geometric shape and processing technology of the parts are complex, and the product manufacturing cost is relatively high
