The differential mechanism has reasonable structural design, the connection and the disconnection of the differential mechanism are smooth, and the operation is simple and comfortable.

Description

A kind of differential mechanism
Technical field
The utility model relates to a kind of differential mechanism, is specially adapted to tractor and uses, and belongs to the differential design technical field.
Background technique
At present, the differential mechanism of the tractor that China produces only is simple planetary structure, the differential lock function is to realize by the engagement that operating mechanism is stirred the flute profile spline, often could dock during operation by stepping on the main clutch pedal, in conjunction with the time need driver's right crus of diaphragm to slam the differential lock pedal always, the driver just can not control the throttle and the brake of tractor effectively like this, has potential safety hazard, and right crus of diaphragm is also tired easily simultaneously.
Summary of the invention
The purpose of this utility model is to solve the deficiency that above-mentioned prior art exists, and a kind of reasonable in design is provided, differential lock in conjunction with, separate steadily simple to operate, comfortable differential mechanism.
The utility model is achieved through the following technical solutions:
A kind of differential mechanism, its special way is to comprise differential casing 2, be plugged with the differential mechanism piston 8 that can move reciprocatingly on the differential casing 2, differential casing 2 forms oil hydraulic cylinder with differential mechanism piston 8, differential casing 2 is provided with the planetary pinion 11 that planet pin 9 reaches around this motion, and differential mechanism piston 8 is connected with friction clutch;
Described friction clutch comprises the friction plate dividing plate 7 that is connected with differential mechanism piston 8, and friction plate dividing plate 7 is connected with friction plate component 3 and differential mechanism piston return spring 5, and the bottom of friction plate component 3 is provided with guiding groove pin 4;
Described friction clutch is a wet clutch;
Described planetary pinion 11 comprises left half axle gear 10 and right axle shaft gear 14;
Described friction plate component 3 is connected with right axle shaft gear 14 by spline;
Described friction plate dividing plate 7 is connected with differential casing 2 by nonstandard profile of tooth;
Described planet pin 9 is connected with planetary pinion minor axis 12, and the two is connected by center connecting plate 13;
The outside of described differential casing 2 is equipped with cap 1, and cap 1 is connected with large conical gear 6.
The utility model reasonable in design when using differential lock, need not to step on main clutch pedal, but the operating button on direct control driver next door realizes, differential lock in conjunction with, separate steadily, impact force is little, easy to operate, eliminated potential safety hazard, improved the travelling comfort of handling and driving effectively.
Description of drawings
Fig. 1: the structural representation of a kind of differential mechanism of the utility model.
Among the figure: 1, cap, 2, differential casing, 3, the friction plate component, 4, guiding groove pin, 5, differential mechanism piston return spring, 6, large conical gear, 7, the friction plate dividing plate, 8, differential mechanism piston, 9, planet pin, 10, left half axle gear, 11, planetary pinion, 12, planetary pinion minor axis, 13, center connecting plate.
Embodiment
Provide embodiment of the present utility model once with reference to the accompanying drawings, be used for the utility model is described further.
Embodiment 1
A kind of differential mechanism of present embodiment, comprise differential casing 2, be plugged with the differential mechanism piston 8 that can move reciprocatingly on the differential casing 2, differential casing 2 forms oil hydraulic cylinder with differential mechanism piston 8, differential casing 2 is provided with the planetary pinion 11 that planet pin 9 reaches around this motion, and differential mechanism piston 8 is connected with friction clutch; Friction clutch comprises the friction plate dividing plate 7 that is connected with differential mechanism piston 8, and friction plate dividing plate 7 is connected with friction plate component 3 and differential mechanism piston return spring 5, and the bottom of friction plate component 3 is provided with guiding groove pin 4; Friction clutch is a wet clutch; Planetary pinion 11 comprises left half axle gear 10 and right axle shaft gear 14; Friction plate component 3 is connected with right axle shaft gear 14 by spline; Friction plate dividing plate 7 is connected with differential casing 2 by nonstandard profile of tooth; Planet pin 9 is connected with planetary pinion minor axis 12, and the two is connected by center connecting plate 13; The outside of differential casing 2 is equipped with cap 1, and cap 1 is connected with large conical gear 6.
Differential casing 2 forms an oil hydraulic cylinder with differential mechanism piston 8, does the control of realization to friction clutch by the left and right moving of differential mechanism piston 8, and when differential mechanism piston 8 unclamped, friction clutch separated, and realizes differential between normal wheel.When 8 pressurisings of differential mechanism piston, the friction clutch combination, right axle shaft gear 14 is as a whole with 2 one-tenth of differential casings, realizes the function of differential lock.
The differential mechanism of present embodiment has friction clutch mechanism, realizes the function of differential lock; Friction clutch is a wet clutch, in conjunction with, separate steadily, impact force is little, and is easy to operate, improved the travelling comfort of handling and driving effectively.
