Problems solved by technology
[0002] The current clutch drive oil cylinder of the same kind, when the high-torque dry friction clutch is controlled and driven, the existing clutch oil cylinder is additionally equipped with a special structural valve, which has a complex structure and insufficient precision. Due to the excessive pressure of the clutch, the huge closing inertia makes the clutch It cannot respond well to the control parameters of the proportional valve, and the semi-engagement point of the clutch cannot be guaranteed, so that the car often stalls when starting, and the smoothness and flexibility of shifting are greatly reduced. It cannot adapt to the high-intensity environment of urban buses. System reliability and technical stability

Embodiment Construction
[0007] exist figure 1 Among them, the present invention is composed of the main oil cylinder 1 and the buffer oil cylinder 3 superimposed. The buffer oil cylinder 3 and the clutch positioning spool 5 are naturally integrated into one. In the present invention, a stepped hole is opened in the central axis of the buffer piston 9 of the buffer oil cylinder 3, and the end of the large hole is at the small end of the buffer piston 3, and the piston 2 of the main oil cylinder is pushed to the position of the half joint point of the clutch to determine the large hole of the clutch buffer piston 9 end length. The small hole end is at the big end of the buffer piston 3. The end face of the large hole of the buffer piston 3 is provided with an overflow groove. Load onto the clutch positioning spool 5 in the buffer piston 9 step holes. The left end of the clutch positioning spool 5 gets a warp to the through hole, which is used to communicate with the axial hole that the right end sq...

The invention provides a clutch positioning oil cylinder of an automatic speed control system electronically controlled by an automobile. The clutch positioning oil cylinder is suitable for automatic control driving of a friction clutch and is a driving execution device of a clutch hydraulic drive electronic automatic control system. When a similar clutch driving oil cylinder is controlled and driven by a large-torque dry-type friction clutch, an existing clutch oil cylinder is provided with an additionally installed special structural valve is completed in structure and poor in accuracy. Due to the fact that clutch press is overlarge, tremendous folding inertia enables a clutch not to make a response to control diameters of a proportional valve, a half bonding point of the clutch is not ensured, flameout often occurs in automobile starting, smoothness and flexibility in gear shifting are remarkably reduced, and the similar clutch driving oil cylinder cannot adapt to the reliability and technical stability of a system in a high-strength using environment, such as an urban bus. The clutch positioning oil cylinder consists of a main oil cylinder and a buffer oil cylinder which are overlaid. The buffer oil cylinder and a clutch positioning valve core are naturally and integrally combined. The clutch positioning oil cylinder is compact in structure, and the expensive proportional valve can be replaced by a common switch magnetic valve.
