Multifunctional clutch and gearbox

Abstract

The invention provides a multifunctional clutch and a gearbox. The clutch comprises a brake gear, a brake shaft, a brake oil pump and a pulse width modulation valve; the brake shaft can rotate around the axis of the brake shaft, and the first end of the brake shaft is coaxially sleeved with an inner rotor gear of the brake oil pump; and an outer rotor gear ring of the brake oil pump can rotate around the axis of the outer rotor gear ring and is connected to the inner rotor gear in a sleeving manner, the inner rotor gear is meshed with the outer rotor gear ring, the inner rotor gear and the outer rotor gear ring are eccentrically arranged, the brake gear is coaxially connected to the second end of the brake shaft in a sleeving manner, and the pulse width modulation valve is used for adjusting the oil pressure of the brake oil pump. The clutch has the functions of speed regulation and clutching, stepless speed regulation can be conducted on a transmission mechanism of the gearbox, torque fluctuation and anti-vibration of the gearbox can be actively absorbed, the problem of gear shifting jerking feeling of the gearbox is solved, the service life of the clutch is prolonged, work is reliable and high in precision, and the comfort experience of a driver is good.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a clutch with multiple functions of speed regulation and clutching and a gearbox with the clutch. Background technique [0002] Existing transmission clutch is to adopt single-plate or multi-plate clutch, and clutch itself is to rely on the clutch function that friction plate is finished. The clutch plate of the existing automobile manual transmission belongs to the dry type single-row clutch, while the existing automatic transmission box of the automobile and the motorcycle transmission box are multi-plate wet clutches, and the passive clutch plate of the clutch is pressed against the clutch by the pressure of the piston or spring. The active clutch plates are engaged to obtain power, otherwise, the clutch plates of the clutch cannot be separated by the pressure of the piston or spring, and the friction between the two clutch plates is lost, so there is no power. [0003] How...

AI Technical Summary

Problems solved by technology

[0003] However, the clutch plates of the existing clutches are engaged by friction, and there is a problem that the service life of the clutch plates is short

In addition, in order to control the separation of the clutch plates to achieve separation, it is necessary to set up a related control mechanism, which makes the structure of the clutch complex and high in cost
