Problems solved by technology

In terms of eliminating blowing loss, they all add a clutch device at the front end of the input shaft of the hydraulic retarder to realize the input and cut-off of the power source, but greatly increase the axial length of the hydraulic retarder , which adds certain difficulties to the arrangement of other components; and limited by the size of the clutch housing, it can only rely on increasing the number of friction plates to provide sufficient friction torque, otherwise the work of the retarder is unreliable

Abstract

The invention discloses a windage loss eliminable hydrodynamic retarder with a friction locking and controlling oil circuit. The hydrodynamic retarder mainly comprises an input shaft, a stator, a rotor, a spline housing, a driving friction plate, a driven friction plate and an end cap. The rotor and the stator are mounted on the input shaft through bearings, and the stator is fixed on a shell through a bolt. The spline housing is fixedly connected with the rotor through rivets and mounted on the input shaft through a bearing. The driving friction plate of a lockup clutch is connected with the input shaft directly through a spline, and can slide on a spline shaft. The driven friction plate is directly connected with the spline housing through the spline, and can slide on the spline housing. The end cap is fixedly connected with an inner flange of the shell through a bolt. A hydraulic control system realizes connection and disconnection of the driving and driven friction plates of the friction type lockup clutch and quick fluid charging and discharging of the retarder by controlling hydraulic oil. Windage loss of the hydrodynamic retarder is eliminated, power loss of an engine is lowered, and the hydrodynamic retarder is simple in structure, stable and reliable in working and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of heavy-duty vehicles, and in particular relates to a hydraulic retarder with friction locking and control oil passage, which can eliminate blowing loss, and is used in the auxiliary braking system of heavy-duty vehicles. technical background [0002] The hydraulic retarder is an auxiliary braking system device for vehicles, which consists of two parts: a stator and a rotor. The rotation of the rotor drives the hydraulic rotation and impacts the stator, and the stator generates a reaction force on the rotor through the liquid, thereby hindering the rotation of the rotor. The hydraulic retarder converts the mechanical energy of the equipment into the thermal energy of the liquid, and dissipates it through the cooling system. [0003] Compared with other braking systems: the braking torque of the hydraulic retarder is proportional to the square of its rotational speed and the fifth power of the diameter of t...
