Problems solved by technology

The existing problem is that the wheel structure combined with the steering knuckle and the swing rod has the function of steering and driving force at the same time, but because it uses the traditional cross-axis steering knuckle, the range of the steering angle is within ±35°. inside, resulting in a large turning radius of the forklift and poor steering flexibility of the forklift
[0003] It can be seen that the above steering structure greatly restricts the forklift in practical applications due to the narrow working environment, and because the forklift adopts rear-wheel steering and front-wheel drive, the weight distribution of the forklift in the unloaded state is that the rear is heavy and the front is light. offset state
When the forklift is driving empty on muddy roads, gravel roads, dirt slope roads, mountain roads, snowy roads, flooded roads and other poor road conditions, the adhesion of the front wheels of the forklift is difficult to guarantee, causing the front wheels of the forklift to slip and lose power. Causes such as breakdown, which makes the forklift's poor survivability restricts the scope of application of the forklift

specific Embodiment 1

[0024] Specific embodiment 1, such as figure 1 As shown, the present invention is a steering drive structure of a vehicle, which is arranged on the front or rear drive axle of the vehicle. The structure includes a steering mechanism fixed on the axle housing 1 of the front or rear drive axle by means of a swing frame 2. The structure of the transmission shaft mechanism 101 between the differential of the front or rear drive axle and the hub side half shaft 5 includes: the active joint 6 parts arranged in sequence along the direction from the power input end to the output end of the transmission shaft mechanism 101, the second 7 parts of a transmission block, 8 parts of an intermediate joint, 9 parts of a second transmission block, and 10 parts of a driven joint. The two adjacent parts are connected end to end to form a multi-element hinge structure. The axis where the hinge shaft of the adjacent hinge structure is located Vertical but not intersecting, the output end of the di...

specific Embodiment 2

[0030] Specific embodiment 2, as a further improvement of the present invention, as Figure 4 As shown, when steering at a large angle, the shaft head 4 may hit the axle housing 1. In order to avoid the impact, a steering limit structure is also provided. The steering limit mechanism includes a first limit device arranged on the shaft head 4 and The second limiting device arranged on the axle housing 1, the first limiting device and the second limiting device form a limiting fit;

[0031] The left and right sides of the shaft head 4 are respectively provided with first limit devices, the first limit devices are limit bolts 15 threaded on the shaft head 4, the limit bolts 15 are full-threaded hexagonal bolts, and the axle housing 1 The left and right sides are provided with second limit devices respectively. The second limit device is a wear-resistant sheet 16. The wear-resistant sheet 1 is arranged on the side of the axle housing 1. The wear-resistant sheet 16 and the limit bo...

Abstract

The invention belongs to the field of vehicle driving axles and particularly relates to a vehicle steering driving structure. The vehicle steering driving structure comprises a steering cylinder mounted on an axle housing and a steering mechanism driven by the steering cylinder, and further comprises a transmission shaft mechanism arranged in the axle housing. The transmission shaft mechanism comprises a driving joint component, a first transmission block component, a middle joint component, a second transmission block component and a driven joint component which are sequentially arranged in the direction from the power input end to the power output end of the transmission shaft mechanism. Every two adjacent components are connected to form hinged structures. The axes of hinged shafts of the adjacent hinged structures are perpendicular to one another but do not intersect. The transmission shaft mechanism provided with the hinged shaft structures is used for driving a hub side half shaft, so that a vehicle wheel has a large steering angle during steering of a vehicle, and the vehicle still has good driving force when steering by the large steering angle. Accordingly, the vehicle has good adaptability under the severe road conditions, and the survivability of the vehicle is improved.

Description

technical field [0001] The invention belongs to the field of vehicle drive axles, and in particular relates to a vehicle steering drive structure. Background technique [0002] The existing vehicle takes a forklift as an example. The steering bridge installed on the forklift to realize the steering function is installed on the rear side of the forklift, including a casing, an oil cylinder, a connecting rod, a steering knuckle, a needle bearing and a thrust bearing. The steering knuckle is a vertical Intersecting the cross shaft, the steering of the forklift is realized by means of the cylinder push-pull connecting rod. The existing problem is that the wheel structure combined with the steering knuckle and the swing rod has the function of steering and driving force at the same time, but because it uses the traditional cross-axis steering knuckle, the range of the steering angle is within ±35°. Inside, the turning radius of the forklift is large, and the steering flexibility...
