Particularly, the utility model provides a kind of hoisting crane walking driver train, comprising:
First motor and second motor;
Bevel gear wheel, said first motor and second motor drive said bevel gear wheel via a bevel pinion respectively simultaneously;
Diff; And
A pair of wheel reduction gear lays respectively at the both sides of said hoisting crane walking driver train,
Wherein, said bevel gear wheel transfers torque to said a pair of wheel reduction gear via said diff.
Preferably, in above-mentioned hoisting crane walking driver train, said diff further comprises: two pairs of differential gears link with said bevel gear wheel respectively; A pair of axle side gear; And a pair of semiaxis, be connected between the axle side gear and wheel reduction gear of the same side.

Fig. 2 shows the lateral plan of the hoisting crane walking driver train of the utility model.
Fig. 3 shows the birds-eye view of the hoisting crane walking driver train of the utility model.
Fig. 4 shows the schematic diagram of the walking driver train of the utility model.
The specific embodiment
The embodiment of the utility model will be described with reference to the drawings now in detail.
Fig. 1～Fig. 3 shows the basic structure according to the hoisting crane walking driver train of the utility model from different angles.With reference now to these accompanying drawings, describe the hoisting crane walking driver train of the utility model in detail.
With reference to figure 1～Fig. 3, the hoisting crane of the utility model walking driver train mainly comprises: the first motor 101-1 and the second motor 101-2, bevel gear wheel 102, diff 103 and a pair of wheel reduction gear 104.
The first motor 101-1 and the second motor 101-2 are positioned opposite to each other, for example the first motor 101-1 and all oblique setting of the second motor 101-2 in the embodiment of Fig. 1～shown in Figure 3.The first motor 101-1 and the second motor 101-2 drive bevel gear wheel 102 via a bevel pinion respectively simultaneously.A pair of wheel reduction gear 104 lays respectively at the both sides of this hoisting crane walking driver train, and this bevel gear wheel 102 transfers torque to a pair of wheel reduction gear 104 via this diff 103.
According to a preferred embodiment, diff 103 may further include: two pairs of differential gears 105, a pair of axle side gear and a pair of semiaxis 106.Differential gear 105 links with bevel gear wheel 102 respectively.This a pair of semiaxis 106 is connected between the axle side gear 105 and wheel reduction gear 104 of the same side, drives wheel reduction gear 104 runnings of both sides respectively.Through the free transmission of a pair of differential gear 105, can accomplish hoisting crane normal direction of rotation function.
This a pair of wheel reduction gear 104 directly links respectively with the wheel hub of a pair of tire 107 of hoisting crane walking driver train both sides, accomplishes driving, and drives the hoisting crane walking.
