Abstract

The utility model discloses a diesel engine with an inner speed change mechanism. Namely the inner side or the outer side of a cylinder of the diesel engine is provided with a gear changing mechanism used for changing the speed of a gear of a crankshaft. The utility model has the advantages that a gear box, a clutch and the cylinder of the diesel engine are combined as an entity under the condition of unchanging the structure and the outer shape of the existing diesel engine, the inner space of the diesel engine is fully utilized, and the function of the diesel engine is added. Transmission links and distance are reduced, a transmission mechanism can be compact and reliable, and the whole diesel engine with an inner speed change mechanism can be installed and utilized conveniently.

Description

A kind of diesel engine that has built-in gear

The utility model relates to a kind of diesel engine, particularly a kind of diesel engine that has built-in gear.

The diesel engine that widely uses by the power that cylinder produces, is given flywheel and outputting power by the direct transmission of connecting rod at present, and self is not with a speed change mechanism, speed change must join gearbox in addition.Though its output speed can carry out suitable adjusting by Throttle Opening Control, its higher output speed generally can not satisfy the actual demand of load.Diesel engine is often as supporting uses such as power engine and tractor, tricycle, rotary cultivators, need frequent speed change during these locomotive works, when supporting use, must join outfit gearbox and clutch between machine, the car, to realize stable shifted needs at diesel engine and institute.This matching method has not only increased the bulk of driving mechanism, and reliability, less stable, and the cost height is installed and used inconvenience.

The purpose of this utility model provides a kind of diesel engine that has built-in gear.

The technical solution of the utility model is, contain cylinder block and gear chamber cover, gear chamber cover and cylinder block constitute gear chamber, crankshaft gear is housed on the cylinder block, it is characterized in that: the inboard of cylinder block or the outside are provided with the gear that can carry out multi-change speed to the rotating speed of crankshaft gear, and its gear and crankshaft gear link by clutch.

Gear is arranged in the gear chamber in the cylinder block outside.

Gear contains clutch shaft, main shaft, countershaft and the declutch shift shaft that is supported on the cylinder block, clutch places on the clutch shaft, major and minor axle is provided with the gear train that can carry out multi-change speed, and declutch shift shaft is provided with the shift fork that can select engagement driving to the gear train middle gear.

Gear also can be arranged in the crankcase of cylinder block inboard.

The utility model has the advantages that, under the constant situation of the structure, the profile that guarantee existing diesel, gearbox and clutch are arranged in the cylinder of diesel engine, the three is integrated, made full use of the inner space of diesel engine, increased the function of diesel engine, reduced transmission link and distance, driving mechanism is compact more, reliable.During with the supporting use of locomotive,, install and use convenient because of not adorning gearbox in addition.

Description of drawings:

Fig. 1 is the utility model embodiment's an overall structure schematic representation;

Fig. 2 is the transmission unfolded drawing of the utility model embodiment gear;

Fig. 3 is the A-A sectional view of Fig. 2.

Below in conjunction with accompanying drawing the utility model embodiment is described in detail further:

Design concept of the present utility model is on the architecture basics that does not change existing diesel, makes full use of the interior locational space of gear chamber float chamber of cylinder of diesel engine 1, sets up gear, to reach the purpose that disposes gear in the Diesel Engine Complete Machine.Present embodiment has provided a kind of diesel engine that has built-in gear in the gear chamber 3 that gear 4 is arranged at cylinder block 1.Gear 4 mainly is made of clutch shaft 10, jack shaft 14, main shaft 16,

countershaft

21 and 26 5 axles of declutch shift shaft.Clutch shaft 10 and jack shaft 14 single-ended being fixedly supported upon on the cylinder block 1, main shaft 16, countershaft 21 and declutch shift shaft 26 are an end bearing on cylinder block 1, and the other end is supported on the gear chamber cover 2.

Clutch shaft 10 is provided with gear 11,12 and clutch 13, and clutch 13 skies are enclosed within on the clutch shaft 10, and gear 12 is connected as a single entity with the housing of clutch 13, and gear 11 links by spline housing with the housing of clutch 13, and gear 12 is meshed with crankshaft gear 9.Be set with gear 15 on the jack shaft 14, gear 15 is meshed with gear 11, gearing in the middle of rising.Major and

minor axle

16,21 is provided with the gear train of four pairs of different gear ratio gears.The upper end of axle 16 is an optical axis, and the lower end is provided with spline, and the upper end of axle 21 is provided with spline, and the lower end is an optical axis.Main shaft 16 is provided with gear 17,18,19,20, and gear 17 is a stem gear, and gear 18,19 is provided with internal spline, and can endwisely slip, and can be splined with axle 16, also can throw off.Main shaft 16 is stretched on the axle head outside gear chamber cover 2 and is provided with sprocket wheel 5, and sprocket wheel 5 is the clutch end of gear 4, also is the clutch end of the utility model diesel engine.Gear 20 skies are enclosed within on the axle 16, and fuse by spline and sprocket wheel 5.Countershaft 21 is provided with gear 22,23,24,25, gear 22,23,24,25 is corresponding to cog and 17,18,19,20 is meshed with spools 16, gear 22 skies are enclosed within on the axle 21, gear 23,24 is provided with internal spline and opens and can slide on axle, can be splined with axle 21, also can throw off, gear 25 is a stem gear with axle 21.Two shift forks 27,28 are housed on the declutch shift shaft 26, have the twice curvilinear groove on the axle 26, rotatablely moving of axle 26 can be converted into the axial motion of shift fork 27,28, with paired handsetting gear 18/23 or gear 19/24, by spline or gear latch selecting different drive paths, thereby realize multistage shifted.The gear chamber cover 2 outer axle heads that stretch out of declutch shift shaft 26 are provided with gear 6, the outside of gear chamber cover 2 is provided with speed-regulating handle 8 and tooth sector 7, tooth sector 7 is meshed with gear 6, by regulating speed-regulating handle 8, can obtain the diesel engine output speed on the required sprocket wheel 5.

Gear train on the major and minor axle of present embodiment is because of being respectively equipped with gear 17 and gear 22, gear 18 and gear 23, gear 19 and gear 24, gear 20 and 25 4 pairs of available drive paths of engaging gear of gear, so can realize the fourth gear speed-regulating function.As, one grade of transmission: when shift fork 27 moves up, the latch that moves on handsetting gear 18 and the gear 23 on the gear 23 inserts in the jack of gear 22, countershaft 21 rotates synchronously with gear 22, gear 17 enters drive path with gear 22 and gear 25 gears 20, the empty engagement of all the other gears promptly realizes one grade of speed change.Its drive path is gear 9/12-clutch-gear 11/15-15/17-17/22,5 outputs of 23-25/20-sprocket wheel; Second gear transmission, third gear transmission, fourth gear drive path are slightly.

Shifting mechanism 4 also can be arranged in the crankcase body of diesel engine.
