Problems solved by technology
However, due to the independent design of the electric motor, cylinder and power output transmission shaft in this structure, the size of the power drive mechanism is relatively long. At the same time, the structure of the power drive mechanism is relatively discrete, which affects the miniaturization of the vehicle.

Embodiment Construction
[0027] In order to make the above objects, features and advantages more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0028] figure 1 is a simplified schematic diagram of the drive system according to an embodiment of the present invention. Such as figure 1 As shown, the drive system 100 of the present invention includes a housing 1 and a motor 2 , a clutch 3 and a hydraulic cylinder 4 installed in the housing 1 .
[0029] The electric machine 2 includes a stator 20 and a rotor 22 . The stator 20 is fixed relative to the housing 1 , and the rotor 22 is mounted on a rotor bracket 24 . The support bearing 6 is installed between the rotor bracket 24 and the hydraulic cylinder 4 . The support bearing 6, which provides radial support, generally comprises an outer ring and an inner ring which are free to move relative to each other. The outer ring of the support bearing 6 supp...

The invention discloses a motor rotor bracket and an integrated design and an application of a clutch hydraulic cylinder, relating to an integrated clutch hydraulic cylinder and a driving system for closing or separating a clutch by using the hydraulic cylinder. The driving system comprises a casing, a stator, a rotor, a rotor bracket, a clutch and a hydraulic cylinder. The strength and the rigidity of the outer wall of a hydraulic cylinder body are enhanced, so that the hydraulic cylinder body not only can be used for bearing the pressure of oil in the cylinder, but also can be used for rotationally supporting the rotor bracket; and a hole is reserved in the middle of the hydraulic cylinder; a main shaft is arranged in the hole, thus the rotating support of the motor rotor and the integrated design of the clutch hydraulic cylinder and the main shaft are realized. The clutch is connected with the rotor bracket through a coupling pair; the coupling pair is driven by a telescopic motion of a piston to be closed or separated; in a closed state, motor power is overlapped on the main shaft through the clutch; and in a separating state, the main shaft motor is separated from the main shaft. By adopting the design, the structure of the driving system is very compact.
Description
【Technical field】 [0001] The invention relates to the field of clutch drive, in particular to an integrated clutch hydraulic cylinder and a drive system. 【Background technique】 [0002] During the whole process of the car from starting to running, it is often necessary to use the clutch. For example, a clutch is installed between the engine and the transmission. On the one hand, it can gradually couple the engine and the transmission, and gradually transmit the power of the engine to the transmission, so as to ensure that the car starts smoothly; Coupling between gears to facilitate gear shifting and reduce shock when shifting gears. A clutch is like a switch that couples or disconnects the power transmission from the engine to the transmission. [0003] At present, a hydraulic control system is usually included in an automobile transmission system, for example, a hydraulic system is used to control the opening and closing state of a clutch in a gear transmission. Hydraul...
