Abstract

The invention discloses a hydraulic steering system. The hydraulic steering system comprises a comprehensive connecting support, a steering machine, a radiator, a steering oil tank and a steering pump, wherein the comprehensive connecting support comprises a beam casting slave plate, a casting machine slave plate and a cross beam connecting plate which are sequentially connected, the back surfaceof the beam cast slave plate is connected to a frame longitudinal beam through a beam casting flat plate, the cross beam connecting plate is connected to a frame transverse beam, the front surface ofthe casting machine slave plate is connected to the bottom ends of casting pillars, the top ends of the casting pillars are connected to support-support connecting holes in a steering machine support,an auxiliary connecting hole is connected to the bottom of a radiating support, the top of the radiating support is connected to the bottom of the radiator and the top of the casting machine slave plate, support-machine connecting holes are connected to the steering machine, a steering machine output shaft on the steering machine penetrates through an output shaft hole and then is connected to asteering vertical arm, the steering vertical arm is arranged in a vertical arm moving cavity in a suspended mode, and the vertical arm moving cavity is defined by the comprehensive connecting support,the steering machine support and the casting pillars together. The hydraulic steering system is not only strong in stability effect, but also high in assembly efficiency.

Description

technical field [0001] The invention relates to a steering system, which belongs to the technical field of automobile steering systems, in particular to a steering hydraulic system and an assembly method thereof. Background technique [0002] The steering pipeline system of traditional commercial vehicles does not have a cooling device. At the same time, engineering vehicles have the characteristics of large loading weight and poor driving conditions. The oil temperature of the pipeline system rises quickly, and once the oil temperature rises, it will not only damage the steering pump, the sealing device of the steering gear and the internal parts, but also make the oil thinner, resulting in a slow rise in the system pressure, and the boost less effective. [0003] The application publication number is CN109484477A, ​​and the application publication date is March 19, 2019. The invention patent application discloses a steering system with a steering oil temperature radiator,...
