Abstract

The utility model discloses a steering drive axle with double steering knuckle arms. The steering drive axle comprises a drive axle body, one steering knuckle arm and one additional steering knuckle arm. The steering knuckle arm and the additional steering knuckle arm are arranged on the left side wheel edge and the right side wheel edge of the drive axle body respectively. The steering knuckle arm and the additional steering knuckle arm are connected with a steering system, and the steering system applies the same force on the steering knuckle arm and the additional steering knuckle arm at the same time. The steering system is a hydraulic system and comprises a steering engine and a steering actuation cylinder system, the steering engine acts on the steering knuckle arm, the steering actuation cylinder system acts on the additional steering knuckle arm, and the force applied on the steering knuckle arm and the force applied on the additional steering knuckle arm belong to the same loop. The left wheel edge and the right wheel edge of the steering drive axle are respectively provided with one steering knuckle arm, and through the control of the steering system, larger and more balanced steering force can be provided for a vehicle in the left-right steering process.

Description

Dual rotation joint arm steering drive axle
Technical field
The utility model relates to a kind of steering drive axle of vehicle, belongs to automobile technical field.
Background technology
Present vehicle generally only has a track arm, and the steering wheel of car is put in left side in a left side, and track arm is on the steering swivel of steeraxle left side; The steering wheel of car is put on right side in the right side, and track arm is on steeraxle right hand steering joint.When Vehicular turn, left and right wheels deflection angle difference, so steering effort size is also different, while inwards turning to, inner side steering swivel deflection angle is large, and steering box stroke is large, and steering effort is little; While turning to towards outside, inner side steering swivel deflection angle is little, and steering box stroke is little, and steering effort is large.Inside and outside while turning to, steering effort varies in size, more painstaking while turning to towards outside.
Summary of the invention
Technical problem to be solved in the utility model is the defect existing for prior art, and a kind of dual rotation drive axle is provided.
For solving this technical matters, the utility model provides a kind of dual rotation joint arm steering drive axle, comprise drive axle body and track arm, also comprise an additional track arm, described track arm and additional track arm are separately positioned on the wheel limit, the left and right sides of drive axle body; Track arm is connected with steering swivel system with additional track arm, and steering swivel system applies equal-sized power to track arm and additional track arm simultaneously.
Described steering swivel system is hydraulic efficiency pressure system, comprises steering box and steering actuation cylinder system, and steering box acts on track arm, and steering actuation cylinder systemic effect is on additional track arm, and the power acting on track arm and additional track arm belongs to the same circuit.
The track arm that car is put on a left side is arranged on the left side of drive axle body, and right side is additional track arm, otherwise car is put on the right side.
Beneficial effect: all there is track arm on the left and right wheels limit of steering drive axle of the present utility model, by the control of steering swivel system, provides while turning to for left and right vehicle wheel more greatly, more balanced steering effort.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 drive axle body, 2 track arms, 3 additional track arms.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises drive axle body 1, track arm 2 and additional track arm 3, and described track arm 2 and additional track arm 3 are separately positioned on the wheel limit, the left and right sides of drive axle body 1.
Described track arm 2 is connected with steering swivel system with additional track arm 3, and steering swivel system applies equal-sized power to track arm 2 and additional track arm 3 simultaneously.
Described steering swivel system is hydraulic efficiency pressure system, comprise steering box and steering actuation cylinder system, steering box acts on track arm 2, and steering actuation cylinder systemic effect is on additional track arm 3, and the power acting on track arm 2 and additional track arm 3 belongs to the same circuit.
The track arm that car is put on a left side is arranged on the left side of drive axle body 1, and right side is additional track arm 3, otherwise car is put on the right side.
Take a left side, putting vehicle is below elaborated (as shown in Figure 1) as example:
In figure, left side is track arm 2, and right side is additional track arm 3; Steering box acts on track arm 2, and steering actuation cylinder systemic effect is on additional track arm 3, and the power acting on track arm 2 and additional track arm 3 belongs to the same circuit, equal and opposite in direction.
When present dynasty left side turns to, left side wheels limit deflection angle compared with right-hand wheel limit is large, and steering swivel stroke is large, and required steering effort is little, therefore steering swivel system advocates to be used in left side; During present dynasty right hand steering, side is contrary, and right-hand wheel limit deflection angle compared with left side wheels limit is large, and steering swivel stroke is large, and required steering effort is little, therefore steering swivel system advocates to be used in right side, left and right turn is compared, turning force equal and opposite in direction.
The left and right wheels limit track arm of steering drive axle of the present utility model is by the control of steering swivel system, when left and right vehicle wheel turns to, provides more greatly while turning to for left and right vehicle wheel, more balanced steering effort.
The above-mentioned embodiment of the utility model, just casehistory, is not only, all within the scope of the utility model or the change being equal in scope of the present utility model all by the utility model, surrounded.
