Problems solved by technology

[0004] The invention provides a pump-type hydraulic coupling to solve the problems of low transmission efficiency of the hydraulic coupling in the current automatic transmission, the highest transmission efficiency is about 89%; large volume and high manufacturing cost; and the existence of the gear pump clutch When the whole vehicle is coasting, the braking function of the engine will be lost. When working at low speed and high pressure, the pressure pulsation will be large; there is no climbing function and the clutch cannot be smoothly clutched.

Abstract

A pump-type hydraulic coupler belongs to a vehicle coupler, in which a pinion is rotating connected in the casing. The pinion inside engaged with a big gear ring. There is a crescent spacer between the pinion and the big gear ring. The back cover of the casing is connected with the casing. One end of connection of the pinion and the casing is connected with a one-way clutch.

Description

technical field [0001] The invention belongs to an automobile clutch, in particular to an automobile coupling. Background technique [0002] Automotive clutches include friction clutches, hydraulic couplings, and electromagnetic clutches. The hydraulic coupling transmits torque by working oil, and the casing and the pump wheel are connected as one, which is the active part; the turbine is opposite to the pump wheel, which is the driven part. When the speed of the pump wheel is low, the turbine cannot be driven, and the driving part and the driven part are separated; as the speed of the pump wheel increases, the turbine is driven, and the driving part and the driven part are in a state of engagement. At present, fluid couplings are widely used in automatic transmission AT or continuously variable transmission CVT vehicles. Due to the limitations of its own structure, the hydraulic coupling has the disadvantages of low transmission efficiency, the highest transmission effici...
