Abstract
The utility model discloses a right crankcase cover used for the outside arrangement of a hydraulic clutch, the through hole of the push lever of a hydraulic cylinder is arranged on the main body of the crankcase cover, the circumference of the through hole is provided with a plurality of mounting holes of the hydraulic cylinder, the mounting holes of the hydraulic cylinder are of blind holes with threads and are positioned at the outer wall of the main body of the crankcase cover. The positions at which the through hole and the mounting holes of the hydraulic cylinder are arranged are provided with heaves, the through hole and the mounting holes of the hydraulic cylinder are arranged on the heaves, the heaves are positioned inside the main body of the crankcase cover. The mounting holes of the hydraulic cylinder of the utility model are the blind holes which are not communicated with the inner cavity of a right cover, and the mounting holes automatically have the function of the oil leakage prevention. At the same time, the right crankcase cover is exclusively designed for the pattern that the hydraulic cylinder is arranged outside the crankcase cover, the structure is compact, and the assembly is simple, thereby being an effective way to achieve hydraulic engaging-disengaging.
Description
Technical field
The utility model relates to a kind of right crankcase cover, specifically refers to the external installation right crankcase cover of a kind of hydraulic coupling.
Background technique
The purpose of clutch is engine output power and driving mechanism are disconnected or to combine, and can clutch finish this work relationship accurately and timely to Security, so extremely important.Traditional clutch of motorcycle operating mechanism is a cable control, and last clutch handle, and then the control drag-line finishes the clutch of clutch by drag-line by operator, this be use at present very many situations.In view of defectives such as drag-line fracture of wire, stretching is elongated, corrosion is broken in use may appear in drag-line, cause the motor clutch unclear, make disabledly, influence is normally used, so begin to have occurred the clutch hydraulic pressure operating mechanism in this field, this mechanism has solved the problems referred to above well.It normally covers on the motor limit oil hydraulic cylinder is installed, and push rod one end that oil hydraulic cylinder is controlled passes motor limit lid and links to each other with clutch, and oil hydraulic cylinder connects oil hydraulic pump by hydraulic tube, and operating grip is installed on the oil hydraulic pump.All clutch hydraulic pressure operating mechanisms that occur all are mounted in external engine at present, for oil hydraulic cylinder is installed, the motor limit covers and is provided with mounting hole, but bad owing to sealing behind the existing motor limit lid installation oil hydraulic cylinder, the machine oil of engine interior in the junction leakage phenomenon can take place.
The model utility content
At the prior art above shortcomings, the purpose of this utility model provides the external installation right crankcase cover of hydraulic coupling that oil leakage phenomenon can not take place after a kind of oil hydraulic cylinder is installed.
The purpose of this utility model is achieved in that the external installation right crankcase cover of a kind of hydraulic coupling, comprise the crankcase cover main body, on the crankcase cover main body, be provided with oil hydraulic cylinder push rod via hole, be provided with some oil hydraulic cylinder mounting holes around via hole, it is characterized in that: described oil hydraulic cylinder mounting hole is threaded blind hole and is positioned at crankcase cover main body outer wall.
Further, described via hole and oil hydraulic cylinder mounting hole position are provided with projection, and via hole and oil hydraulic cylinder mounting hole are located on the projection, projection and crankcase cover main body one die cast.Described projection is positioned at crankcase cover main body inboard.
Described oil hydraulic cylinder mounting hole is three and is evenly distributed on the same circumference.
The utility model oil hydraulic cylinder mounting hole is a blind hole, does not communicate with right cover cavity, self has had the function that prevents leakage of oil.When concrete the installation, oil sealing sealing can be adopted in case leak-stopping oil between oil hydraulic cylinder push rod via hole and the oil hydraulic cylinder push rod.
Simultaneously, this right crankcase cover aims at oil hydraulic cylinder and is installed in that it is outside and design, and compact structure is succinct, installs simply, is the effective means that realizes hydraulic clutch.
Description of drawings

Fig. 2-Figure 1B-B sectional view.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, from the figure as can be seen, the external installation right crankcase cover of hydraulic coupling of the present utility model, comprise crankcase cover main body 1, on crankcase cover main body 1, be provided with oil hydraulic cylinder push rod via hole 2, be provided with some oil hydraulic cylinder mounting holes 3 around via hole 2, described oil hydraulic cylinder mounting hole 3 is for threaded blind hole and be positioned at crankcase cover main body 1 outer wall.Because crankcase cover main body 1 wall thickness is thinner, threaded blind hole directly is set in the above can't install, can not guarantee join strength, it is to be provided with projection 4 at oil hydraulic cylinder push rod via hole 2 and oil hydraulic cylinder mounting hole 3 (blind hole) position that the historical facts or anecdotes border adds man-hour, see Fig. 2, via hole 2 and oil hydraulic cylinder mounting hole 3 are located on the projection 4, projection 4 and crankcase cover main body 1 one die cast, described projection 4 is positioned at crankcase cover main body 1 inboard.The wall thickness at crankcase cover main body place that is equivalent to via hole 2 and oil hydraulic cylinder mounting hole 3 places is greater than other local wall thickness of crankcase cover main body.
Further, described oil hydraulic cylinder mounting hole 3 is three and is evenly distributed on the same circumference that so guarantee to install firmly, reliably, this circumference is concentric with oil hydraulic cylinder push rod via hole 2.
This right crankcase cover is a cancellation clutch control arm on the basis of former crankcase cover, increasing external oil hydraulic cylinder mounting hole 3 and oil hydraulic cylinder push rod via hole 2 forms, oil hydraulic cylinder is installed on this crankcase cover oil hydraulic cylinder mounting hole 3 by bolt, and the oil hydraulic cylinder push rod passes center via hole 2 and contacts with clutch push rod.Oil hydraulic cylinder mounting hole 3 adopts the blind hole design, so do not communicate with right cover cavity, can prevent leakage of oil.
