A fuel engine and electric motor linkage separation system

Abstract

The embodiment of the invention discloses a linkage separation system for a fuel oil engine and an electromotor. The linkage separation system comprises a driving disc and a driven disc of an engagement and disengagement mechanism. The driving disc is connected with a power output shaft of the fuel oil engine, the driven disc is connected with a power output shaft of the electromotor, the power output shaft of the electromotor serves as a power output shaft of the engagement and disengagement mechanism at the same time, two or more symmetrically-distributed engagement and disengagement blocks are arranged between an inner cavity of the driving disc and the outer end face of the driven disc, and the outer end face of the driven disc is of a ratchet wheel type structure. When the driving disc runs, the end faces of the engagement and disengagement blocks are connected with the outer end face of the driven disc in a ratchet wheel and pawl clamping contact mode. By means of the linkage separation system, the contact mode of the end faces of the engagement and disengagement blocks and the outer end face of the driven disc is a surface contact mode instead of a linear contact mode, the stressed area is increased, larger torsion and power can be transmitted, transmission is more reliable, and the contact area of a clutch and transmission teeth can be automatically adjusted due to long-time abrasion of the clutch; the linkage separation system can be used in a dry mode or a refueling mode, and the service life of the linkage separation system used in the refueling mode is more than three times that of the linkage separation system used in the dry mode.

Description

technical field [0001] The invention relates to a linkage clutch structure of a fuel engine and an electric motor, in particular to a linkage separation system of a fuel engine and an electric motor. Background technique [0002] With the improvement of people's living standards, motor vehicles have become a common means of transportation necessary for people's work and life. However, with the popularization of motor vehicles, energy problems and air pollution problems caused by motor vehicles powered by gasoline and diesel engines It has become a problem that governments and related enterprises attach great importance to. Motor vehicles powered by electricity, that is, electric vehicles, have developed rapidly in recent years and their applications are increasing. However, pure electric vehicles are limited by the charging time and battery life on the mileage, and have obvious defects; therefore, fuel engines and electric motors are used as power. The hybrid motor vehicle ...

AI Technical Summary

Problems solved by technology

The linkage clutch mechanism commonly used in the prior art is a ball type one-way clutch (such as figure 1 shown) and roller clutches (as figure 2 As shown), it is characterized in that the driving disc and driven disc of the clutch mechanism can be engaged or separated through balls or rollers, so as to realize the linkage or separation of the fuel engine and the output shaft of the electric motor. The balls or rollers of this type of clutch and the active The contact between the disc and the driven disc is point-like contact. Because the contact surface is too small, it cannot adapt to the transmission of large torque, and it is easy to cause serious wear of the balls or rollers, uneven power transmission, and easy damage; especially for roller clutches. Not only the structure and size are large, but also it cannot adapt to the transmission of large torque. After a period of use, the rollers will be slightly worn, or due to dust and oil, they will lose their transmission effect; the ball clutch is relatively small in size, but the structure cannot adapt to large torque. Torque transmission, it is easy to cause serious wear or direct damage to the balls in the case of sudden torque. In severe cases, it will burst or the transmission structure will be stuck, resulting in power failure of the transmission system. The above two clutch structures are under high torque transmission. Obvious defects, high maintenance costs, not even suitable for use
