The invention discloses a low drag torque type clutch suitable for high rotation speed, comprising: a left support casing, a driving shaft, a piston, an end cover of an auxiliary oil cylinder, a right supporting casing, a passive shaft, a pair of plates, a friction plate and a separation spring ;The piston is installed between the outer circumferential surface of the driving shaft and the inner circumferential surface of the cylinder of the driving shaft; the cylindrical section of the driven shaft is coaxially installed outside the driving shaft; the dual plate and the friction plate are coaxially installed on the between the outer circumferential surface and the inner circumferential surface of the cylindrical section of the driven shaft; the end cover of the auxiliary oil cylinder is coaxially installed between the outer circumferential surface of the large diameter section of the driven shaft and the inner circumferential surface of the cylinder of the driving shaft; the separation spring It is installed between the end face of the end cover of the auxiliary oil cylinder and the end face of the piston; the left support shell is sleeved on the driving shaft; the right support shell is sleeved on the passive shaft; and the left support shell and the right support shell are butted and fixedly connected; The invention can solve the problems of high drag torque, poor stability and eccentric excitation of the existing high-power clutch at high rotational speed.
Description
technical field [0001] The invention belongs to the technical field of clutches, and in particular relates to a low drag torque clutch suitable for high rotational speed. Background technique [0002] Under the new situation, high mobility and quick response have become the urgent needs of special vehicles, which extends to the transmission of vehicles, which are high power density, high reliability and convenient handling. The most effective measure to improve the power density of the transmission is to reduce the transmission torque by increasing the input speed. High reliability is to improve the operating stability of the clutch. Convenient handling is to reduce the operation links and control objects of the transmission. At present, the original transmission scheme is no longer suitable for the new transmission needs, and it is urgent to develop a new transmission scheme. The clutch is the most basic bearing and control unit in the transmission device. In the new trans...
