Embodiment Construction

[0043] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0044] Such as Figure 1 to Figure 3 As shown, the steering pump 2 is a double steering pump, and the steering pump 2 is provided with a steering pump oil inlet 14, and the steering pump oil inlet 14 is connected with the oil tank 4 through a pipeline. The pump 2 is provided with two steering pump oil outlets 15, and the two steering pump oil outlets 15 are connected with the steering gear 1 through pipelines. The oil that enters the steering pump 2 through the oil inlet 14 of the steering pump is low-pressure oil, and after being converted by the steering pump 2, the oil at the oil outlet 15 of the steering pump is high-pressure oil. The high-pressure oil enters the steering gear 1 through the...

Abstract

The invention provides a steering pump. The steering pump is provided with a steering pump oil inlet and two steering pump oil outlets, wherein the steering pump oil inlet is connected with an oil tank, and the two steering pump oil outlets are connected with a steering device. The invention further provides the steering device comprising two steering device oil inlets, two steering device oil outlets and two boosting cylinder connectors, wherein the two steering device oil inlets are used for connecting with the steering pump, the two steering device oil outlets are connected with the oil tank, and the two boosting cylinder connectors are used for connecting with boosting cylinders. A rotary valve used for controlling oilway flow direction is arranged on the steering device. In addition, the invention provides a steering system comprising the steering device, the steering pump, the oil tank, the first boosting cylinder and the second boosting cylinder. The steering system solves the problem that the automobile is heavy in turning and slow-moving in steering. Finally, the invention provides the automobile comprising the steering system.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a steering pump, a steering gear, a steering system and a vehicle. Background technique [0002] At present, in large vehicles with more than four axles, the first axle and the second axle are usually steering axles, and the steering mechanism and steering system generally adopt hydraulic power steering, that is, the hydraulic steering pump is used to drive the steering gear and finally drive the steering axle to achieve steering. And the widely used steering pump at present comprises a steering pump oil inlet and a steering pump oil outlet, and the flow rate is less than 25L / min, and the steering gear only includes a steering gear oil inlet and a steering gear oil outlet, and the steering gear The output torque is less than 7000N·m. If the hydraulic system composed of the steering pump and the steering gear including this structure is used, there is usually insufficient flow...
