Problems solved by technology

At present, multi-mode clutches are often used in engineering applications. The actuator structure is relatively complex, and one actuator contains multiple spring structures, but the spring structure has a certain fatigue limit, and when the same process spring operates in the same environment, its fatigue limit is also They are not the same, so it is easy to cause the multi-mode clutch actuator to be difficult to return, which will eventually affect the performance and service life of the multi-mode clutch actuator, thereby affecting the execution of the multi-mode clutch under various working conditions and affecting the driving performance of the car

Embodiment 1

[0016] A multi-mode clutch actuator such as figure 1 As shown, it includes a cavity 1, an actuating plunger 2 and an actuating rod 3, the actuating plunger 2 includes a thick plunger rod 2-1 and a thin plunger rod 2-2, and the thick plunger rod 2-1 is as a whole T-shaped, the end of the thick plunger rod 2-1 with a smaller section diameter is fixedly connected with the thin plunger rod 2-2, one end of the cavity 1 is plugged with a first screw plug 4, and the other end of the cavity is plugged with a The second screw plug 5, the second screw plug 5 is covered with an O-ring 6, the O-ring 6 is used to seal the oil passage between the cavity 1 and the second screw plug 5, and the inner end of the second screw plug 5 is A groove 7 is opened on the end surface, a first oil inlet hole 8 is opened on the second screw plug 5 and the first oil inlet hole 8 communicates with the groove 7, and the inside of the cavity 1 is from the first screw plug 4 to the second screw plug. The direc...

Embodiment 2

[0022] A multi-mode clutch actuator, the structure of which is similar to that of the multi-mode clutch actuator in Embodiment 1, the difference is that the first limit stop is a flat plate structure as a whole, and the second limit stop is a whole It is a flat plate structure, the distance between the actuating plunger and the first screw plug, the thick plunger rod of the actuating plunger is placed at one end of the first installation area and the inner wall of the end of the first installation area away from the first screw plug The distance between them, the distance between the actuating plunger and the bottom of the groove of the second screw plug are all equal to the movable distance between the first limit stopper and the second limit stopper.

Embodiment 3

[0024]A multi-mode clutch actuator, its structure is similar to that of the multi-mode clutch actuator in Embodiment 1, the difference lies in: the distance between the actuating plunger and the first screw plug, the actuating column The distance between the plug and the bottom of the groove of the second screw plug is greater than the movable distance between the first limit stopper and the second limit stopper, and the thick plunger rod of the actuating plunger is placed in the first stopper. The distance between one end of the installation area and the inner wall of the end of the first installation area away from the first screw plug is equal to the movable distance between the first limit stopper and the second limit stopper.

Abstract

The invention provides a multi-mode clutch actuator. A screw plug is arranged at one end of a cavity opening in a plugged mode, a movable shaft mounting area is formed between a cavity and the screw plug, an actuating shaft is installed at the right middle position of an actuating shaft mounting region in a matched mode, the side faces of the two ends of the actuating shaft are attached to the inner wall of the actuating shaft mounting region, a space is reserved between the middle part of the actuating shaft and the inner wall of the actuating shaft mounting region, bosses are symmetrically arranged on the end faces of the two ends of the actuating shaft, the bosses are sleeved with return springs, and the positions of the return springs are beyond the bosses; and a first hydraulic oil channel and a first oil inlet hole which communicate are formed in the outer side of one end of the cavity, a second hydraulic oil channel and a second oil inlet hole which communicate are formed in theouter side of the other end of the cavity, an executing block sleeves the middle position of the actuating shaft, the middle position of an actuating rod is arranged on the cavity through a fixing device, one end of the actuating rod is inserted into the actuating block, and the other end of the actuating rod extends out of the cavity. The multi-mode clutch actuator is simple in structure and wide in application range.

Description

technical field [0001] The invention relates to a multimode clutch actuator. Background technique [0002] At present, in the transmission of hybrid electric vehicles, it is often necessary to apply multi-mode clutches to realize different execution modes of various working conditions of hybrid electric vehicles, and the use of multi-mode clutches is inseparable from the matching actuators. At present, multi-mode clutches are often used in engineering applications. The actuator structure is relatively complex, and one actuator contains multiple spring structures, but the spring structure has a certain fatigue limit, and when the same process spring operates in the same environment, its fatigue limit is also They are not the same, so it is easy to cause the multi-mode clutch actuator to be difficult to return, which will eventually affect the performance and service life of the multi-mode clutch actuator, thereby affecting the execution of the multi-mode clutch under various ...
