Frame, two degrees of freedom linkwork, hydraulic steering mechanism and Rear frame, front frame pass through two degrees of freedom linkwork and fluid-link steering
Mechanism connects Rear frame, and two degrees of freedom linkwork and hydraulic steering mechanism are realized between front frame and Rear frame along vehicle frame direction
Longitudinal oscillation and the lateral rotation along vertical direction of principal axis.The articulated chassis employs the vehicle frame of two direction of rotation, due to
It turns to and is realized dependent on the angle adjustment between front/rear frame, cause fame dimensions larger, front and rear globality is poor.In addition, by
A power source is used, it is necessary to which power could be transferred to wheel by complicated transmission system in vehicle, arrangement is difficult,
Cost is higher, and can not be travelled once power source breaks down vehicle.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention provides a kind of split type dual-drive electric automobile chassis, lead to
It crosses split type setting and can guarantee that vehicle traveling realizes that automobile four-wheel lands simultaneously in concave-convex road surface, while using dual power source just
In the arrangement of vehicle, manufacture cost is effectively reduced, also can be when a power source break down wherein, vehicle still can be after continuing
It sails.
To achieve these goals, the technical solution adopted by the present invention is：A kind of split type dual-drive electric automobile chassis,
Including Qian Qiao chassis and rear axle chassis, a hinged seat is respectively equipped on the Qian Qiao chassis and rear axle chassis, two hinged seats lead to
It crosses shaft to be hinged, relatively rotates Qian Qiao chassis and rear axle the chassis axis centered on shaft, the Qian Qiao chassis is equipped with preceding bridge
Rear axle chassis described in driving motor is equipped with rear bridge driven motor, and preceding bridge driving motor is electrically connected with preceding bridge controller, and rear axle drives
Dynamic motor is electrically connected with rear axle electric machine controller, and automobile power source is preceding bridge electric machine controller and rear axle motor control by vehicle body switch
Device power supply processed.
Further, the vehicle body switch is third gear switch, is made of three forerunner's shelves, rear-guard shelves, 4 wheel driven shelves gears, vehicle
Automobile power source is connected with preceding bridge electric machine controller when body switch is in forerunner's shelves, bridge driving motor before preceding bridge electric machine controller driving
Action；Automobile power source is connected with rear axle electric machine controller when vehicle body switch is in rear-guard shelves, rear axle electric machine controller control rear axle
Driving motor acts；Automobile power source and preceding bridge electric machine controller and rear axle electric machine controller be simultaneously when vehicle body switch is in 4 wheel driven shelves
Connection, bridge driving motor and rear bridge driven motor action before preceding bridge electric machine controller respectively drives with rear axle electric machine controller.
Further, the preceding bridge driving motor is identical with the model of rear bridge driven motor.
Further, the preceding bridge electric machine controller is identical with the model of rear axle electric machine controller.
Compared with prior art, the invention has the advantages that：
1) present invention is by the way that Qian Qiao chassis is hinged with rear axle chassis by shaft, before making vehicle when passing through concave-convex road surface
Bridge chassis relatively rotates under gravity with rear axle chassis, realizes two bridge four-wheels and lands, improves entire vehicle tyre
Adhesive force, so as to greatly improve the cross-country ability of vehicle.It is hinged simultaneously as eliminating steering, using only common vehicle
Steering structure is taken turns, makes integral body size smaller；
2) using Dual-motors Driving tandem axle, and realize that tandem axle is flexible coupling, reduce structural member, complete machine is arranged more
Add flexibility, and due to being used as power source using two sets motors, vehicle power can be with Redundant Control, when the feelings of a power source loss
Vehicle can continue to travel under condition, improve the reliability on chassis, and improve the cross-country ability of electric vehicle.
Description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is position view of present invention when by concave-convex road surface；
Fig. 3 is the electric control principle block diagram of the present invention.
In figure：1st, preceding bridge driving motor, 2, Qian Qiao chassis, 3, shaft, 4, rear bridge driven motor, 5, rear axle chassis.
Specific embodiment
The invention will be further described below.
As shown in Figure 1 to Figure 3, a kind of split type dual-drive electric automobile chassis, including Qian Qiao chassis 2 and rear axle chassis 5,
