Abstract

The utility model discloses a clutch controller of a motor vehicle differential mechanism, which can control the driving wheels on the both sides of a motor vehicle to synchronously rotate. Clutches are arranged on the casing and the half shaft of a differential mechanism. The clutch is controlled by the shifting fork of an operation rod. The rotation of the same angular speed of the casing and the half shaft of a differential mechanism can be controlled at any time. Then the purpose of synchronous rotation of the driving wheels on the both sides of a motor vehicle can be achieved. The utility model can reduce the phenomena of vehicle failure on a mud pavement, slipping on a smooth pavement, etc. The utility model can be used for motor vehicles with a differential mechanism.

Description

The clutch control device of self-propelled vehicle diff

The utility model relates to the driving system of self-propelled vehicle, particularly relates to the diff and the power-transfer clutch of driving system.

At present, the function of self-propelled vehicle diff, can only be subjected to the size of resistance along with the bilateral drive wheel, and change bilateral drive wheel rotative speed separately at any time, when the drive wheel of a side was maked somebody a mere figurehead or skidded on smooth side, the drive wheel of opposite side then greatly can not rotate, so self-propelled vehicle just can't advance because of resistance, thereby increased self-propelled vehicle at smooth and muddy road surface, the difficult problem of advancing.

The purpose of this utility model is: overcome the deficiencies in the prior art, design a kind of normal function that neither influences diff, can control diff at any time again, make the height of the self-propelled vehicle diff of the synchronous rotation of self-propelled vehicle bilateral drive wheel close the device control setup.Simple in structure, control comfort has increased the function of motor drive system, has reduced the generation of self-propelled vehicle in phenomenons such as muddy road surface fall into that car and smooth road are skidded.

The utility model comprises power-transfer clutch, differential gear box and semiaxis, described power-transfer clutch is the main gear by the control of joystick upper shift fork, form with the inner gear of fixing with screw rod on the differential gear box, main gear links with spline (or flat key) and semiaxis, can on semiaxis, move, can be meshed with inner gear and separate.

Said power-transfer clutch also can be side tooth clutch or the friction type power-transfer clutch.

The utility model has the advantages that: the synchronous rotation of controlling machine motor-car bilateral drive wheel at any time as required, increased the function of driving system, simple in structure, control comfort has reduced the generation of phenomenons such as the self-propelled vehicle muddy road surface falls into that car and smooth road are skidded.

As Fig. 1 is the sectional view of internal-gear type power-transfer clutch for the utility model power-transfer clutch.

A most preferred embodiment of the present utility model: as Fig. 1, main gear 2 usefulness splines (or flat key) link with semiaxis 3, and under the effect of joystick upper shift fork 5, can axially move, with the interior mutually ingear inner gear 4 of main gear 2, be fixed on the differential gear box 1 with screw rod 6.

The principle of work of this device is: be that main gear 2 breaks away from inner gear 4 as shown in Figure 1, diff is in normal working.

When joystick manipulation shift fork 5 with main gear 2, stir left, when meshing with inner gear 4 is interior mutually, because of main gear 2 and semiaxis 3 are that spline (or flat key) connects, so differential gear box 1 combines as a whole by main gear 2 with semiaxis 3, with the cireular frequency rotation, make diff lose differential function, reached the purpose of self-propelled vehicle bilateral drive wheel with the speed rotation.

Position shown on shift fork 5 is schemed main gear for 2 groups times, diff recovers normal function again.

Be noted that at last: the installation and the principle of work of side tooth clutch and the friction type power-transfer clutch, identical with above-mentioned internal-gear type power-transfer clutch, so repeat no more.

In addition, said inner gear is fixed on the differential gear box with screw rod, also can be that inner gear and differential gear box are cast as one.

Claims

1. the clutch control device of a self-propelled vehicle diff, it comprises from Chou differential gear box and semiaxis, the main gear and the semiaxis that it is characterized in that the fork controls on the joystick link with spline (or flat key), can axially move, inner gear is fixed on the differential gear box with screw rod, and the fork controls main gear separates and engagement with inner gear.

2. the clutch control device of self-propelled vehicle diff according to claim 1 is characterized in that: power-transfer clutch can be the internal-gear type power-transfer clutch, also can be side tooth clutch or the friction type power-transfer clutch.
