Abstract
The utility model relates to a mechanical gear box for engineering machines such as fork truck, etc., which serves to provide a maintenance-free, long service life of a clutch and more environmental protective mechanical gear box with a vulcan coupling, and is characterized in that, a clutch cylinder body sleeve is arranged on a gear box input axis, an annular piston is arranged on the clutch cylinder body; a clutch gear is in annualarity and its axial direction end is clamped to inner wall of the clutch cylinder wall. A clapboard, a waveform spring, a friction plate, baffle and a check ring are sleeved to external circumference of such end in sequence. The utility model has the advantages of long service life without the necessity of maintenance and can be operated easily by driver.
Description
Technical field
The utility model relates to engineering machinery mechanical gear boxes such as fork truck.
Background technique
At present, the domestic mechanical gearbox clutch mechanism that is used for engineering machinery such as fork truck adopts dry type single-leaf spring clutch more.This clutch mechanism is simple, separation is thorough, compact dimensions, easy to adjust, and the secondary part rotary inertia is little, and binding energy guarantees steadily.But also have limitation as follows: at first the friction plate life-span easy to wear not long, particularly in the field of work under bad environment, for example vehicle short distance in mine comes and goes carrying, clutch frequency of utilization height, friction plate is changed frequently.And the vehicle that has could be changed after motor need being pulled down.Secondly, because adopt this clutch mechanism, gearbox can not be with pump, can only adopt motor direct driving pump or motor directly to be with pump structure.These two kinds of structures all exist because of engine vibration makes the pump work instability, and the life-span is short, requires the speed range of pump narrow, shortcomings such as installation and maintenance difficult.And make main engine factory be limited by motor producer, leeway, selective space is less.Once more, most on-off control mechanisms adopts the leverage of machinery, and clutch pedal power is big, fatiguability during driver's operation.
Summary of the invention
The purpose of this utility model is: a kind of Maintenance free, clutch long service life, the mechanical gear box with fluid clutch of environmental protection more are provided.
Concrete structural design scheme is as follows:
Mechanical gear box with fluid clutch comprises main reducing gear assembly, control valve assembly, transmission case assembly and clutch; It is characterized in that:
A, described clutch are fluid clutch, clutch cylinder body 15 is set on the gearbox input shaft 17, be provided with annular piston 14 in the ring-shaped cavity of clutch cylinder body 15, clutch cylinder body 15 tops and a side-walls corresponding with piston 14 are respectively equipped with clutch oil duct 16 and cooling oil duct 18;
B, also comprise pump drive mechanism, its idle gear 24 respectively with clutch gear 7 and pump drive gear 23 engagements, idle gear 24 and pump drive gear 23 are located on the gear box by idle pulley 21 and axle 22 respectively, axle 22 is connecting oil pump 25.
Useful technique effect of the present utility model is:
1, friction plate of the present utility model is forced big flow oil cooling but, reduces wear good heat dissipation effect, operating temperature is low, long service life, and normal use is generally 8～10 times of dry clutch down, and Maintenance free maintenance in use, so greatly increase work efficiency.
2, the clutch of this device is handled and is adopted valve rod control, and the about 25N of steering force is light flexibly.Avoid existing machinery to handle the foot-operated power of 130～250N, alleviated driver's fatigue, increased driving comfortability;
3, this device has been avoided the dry friction of existing machinery gearbox clutch friction plate, can not give out a pungent smell and smog, more environmental protection.
4, friction pair annular working area of the present utility model is big, and the polydisc structure can obtain bigger friction torque under less liner pressure, and volume is littler;
5, gearbox of the present utility model can be with PTO, makes main engine factory widen the range of choice of supporting motor;
6, the pump work of this device is stable, and installation, maintenance is convenient.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Mechanical gear box with fluid clutch comprises main reducing gear assembly 5, control valve assembly 4, transmission case assembly 3, pump drive assembly 2 and clutch pack 1.
Clutch is a fluid clutch, clutch cylinder body 15 is sleeved on the gearbox input shaft 17, be set with annular piston 14 in the ring-shaped cavity of clutch cylinder body 15, the clutch cylinder body 15 two sides place corresponding with piston 14 is provided with clutch oil duct 16 and cooling oil duct 18 respectively.
The idle gear 24 of its pump drive mechanism meshes with clutch gear 7 and pump drive gear 23 respectively, and idle gear 24 and pump drive gear 23 are located on the gear box by idle pulley 21 and axle 22 respectively, and axle 22 is connecting oil pump 25.
This device working principle is as follows:
Two-part before and after supported plate 20 of fluid clutch and oil sealing are divided into, the front portion is a dry type, the rear portion is a wet type.Tablet assembly 6 is connected with engine flywheel, gives clutch gear 7 with transmission of power, and clutch gear 7 drives oil feed pump 19 by idle gear 24, pump drive gear 23, drives former and later two power delivery outlets simultaneously.Oil feed pump 19 from the gearbox drain pan oily sucking-off, deliver in the control valve 4 by oil duct after becoming pressure oil, be transported in the clutch cylinder body 15 by control valve 4 again, promote piston 14, overcome wavy spring 12, make friction plate 11 contact, compress, be transferred to gearbox 3 by frictional force Jiang engine power with dividing plate 13.Gearbox gear-shift is realized gear shift by gear shifting handle bar, reverse shift fork, synchronizer.Gearbox arrives main reducing gear with transmission of power again, and this mechanical gear box has the first two two or four gear in back.
