Abstract
The utility model relates to a steering gear of a lorry, which comprises a dynamic traversing mechanism, a plumbing arm, a straight pulled rod and a transitional oscillating beam, wherein the straight pulled rod is provided with a first axle straight pulled rod and a second axle straight pulled rod, and the front end of the first straight pulled rod is moveably connected with the lower end of the plumbing arm, and the rear end of the first straight pulled rod is moveably connected with a first front axle. The transitional oscillating beam is provided with a first transitional oscillating beam and a second transitional oscillating beam, both ends of a first transitional draw rod are respectively and moveably connected with the plumbing arm and the first transitional oscillating beam, the front end and the rear end of the second transitional draw rod are respectively and moveably connected with the rear end of the first transitional oscillating beam and the second transitional oscillating beam, and the second transitional oscillating beam is moveably connected with the front end of the second axle straight pulled rod, and the rear end of the second axle straight pulled rod is moveably connected with a second front axle. The steering gear can lead double front axles to be synchronously steered, and reduce the abrasion of tiers.
Description
Technical field
The utility model belongs to truck and is used for the car chassis that remoulded car is used, and relates to a kind of steering gear of truck chassis specifically.
Background technology
Steering gear is the steering power hub transmission of automobile, the steering swivel that it passes to the steeraxle both sides with the power and the motion of deflector output, make both sides wheel flutter deflection, and make the wheel flutter angle of inclination by certain relationship change, wheel and ground-surface slide relative are as far as possible little during with the assurance motor turning.At present, China part auto vendor has produced the automobile of two propons, and its rocking arm is fixed on the rocker arm support by straight pin, link to each other with vehicle frame, but since between transition pull bar and transition swing arm lack, make two propons be difficult to turn to simultaneously, cause very big wearing and tearing to tire.
The utility model content
The utility model has been designed and developed out a kind of pair propons that can make and has been turned to synchronously at the deficiencies in the prior art, reduces the two propons steering gears of truck of wear on tyres.
The utility model is achieved through the following technical solutions:
A kind of steering gear of truck, including moving veer machine, the plumbing arm that is connected with moving veer machine, the front end of drag link is connected with plumbing arm, its rear end is connected with the transition rocking arm, described drag link is provided with the first bridge drag link and the second bridge drag link, the front end of the described first bridge drag link and described plumbing arm lower end flexibly connect, and the first bridge drag link rear end and first propons flexibly connect; Described transition swing arm is provided with the first transition swing arm and the second transition swing arm, the two ends of the first transition pull bar flexibly connect with the plumbing arm and the first transition swing arm respectively, the rear and front end of the second transition pull bar flexibly connects with the rear end of the first transition swing arm and the second transition swing arm respectively, the front end of the second transition swing arm and the second bridge drag link flexibly connects, and the rear end of the second bridge drag link and second propons flexibly connect.
A kind of steering gear of truck, the rear end of the described second transition swing arm is connected with the flexible end of hydraulic ram.
The utility model has adopted two preceding bridge constructions, and load-carrying capacity has been improved greatly.Simultaneously, two propons connect by drag link, transition rocking arm and transition pull bar respectively, have guaranteed that two propons turn to simultaneously, have reduced the Tyte Wear degree.For making handling maneuver light, assembled hydraulic actuating cylinder, promote piston motion by high pressure oil, drive the swing of the second transition rocking arm with this, realize turning to of the second propons accurate and flexible.
Description of drawings
Accompanying drawing is a structural representation.
The specific embodiment
Shown in accompanying drawing.
The front end that the utility model includes moving veer machine 1, the plumbing arm 2 that is connected with moving veer machine 1, drag link is connected with plumbing arm 2, its rear end is connected with the transition rocking arm, described drag link is provided with the first bridge drag link 3 and the second bridge drag link 8, the front end of the described first bridge drag link 3 and described plumbing arm 2 lower ends flexibly connect, and the first bridge drag link, 3 rear ends and first propons 10 flexibly connect; Described transition swing arm is provided with the first transition swing arm 5 and the second transition swing arm 7, the two ends of the first transition pull bar 4 flexibly connect with the plumbing arm 2 and the first transition swing arm 5 respectively, the rear and front end of the second transition pull bar 6 flexibly connects with the rear end of the first transition swing arm 5 and the second transition swing arm 7 respectively, the front end of the second transition swing arm 7 and the second bridge drag link 8 flexibly connects, and the rear end of the second bridge drag link 8 and second propons 11 flexibly connect.The rear end of the second transition swing arm 7 is connected with the flexible end of hydraulic ram 9.
The utility model connects with rocking arm between each pull bar, and the power of exporting from deflector links to each other with first propons 10 through plumbing arm 2, the first bridge drag link 3, and first propons 10 is turned to; Simultaneously, the first transition pull bar, 6 two ends bulbs link to each other with the first transition swing arm 5 with plumbing arm 2 respectively, and the second transition pull bar 6 couples together the first transition swing arm 5 and the second transition swing arm 7, the second transition swing arm 7 is connected with second propons 11 by the second bridge drag link 8, when this structure turned to the propons 10 of winning, second propons 11 also turned to.In addition, for guaranteeing there is not movement interference, requiring the gap between transition pull bar fitting surface and the leaf spring hanger is 134mm.For making handling maneuver light, assembled hydraulic ram 9, promote piston motion by high pressure oil, drive second transition rocking arm swing 7 with this, realize turning to smoothly of second propons 11.
Claims (2)
1, a kind of steering gear of truck, including moving veer machine, the plumbing arm that is connected with moving veer machine, the front end of drag link is connected with plumbing arm, its rear end is connected with the transition rocking arm, it is characterized in that described drag link is provided with the first bridge drag link and the second bridge drag link, the front end of the described first bridge drag link and described plumbing arm lower end flexibly connect, and the first bridge drag link rear end and first propons flexibly connect; Described transition swing arm is provided with the first transition swing arm and the second transition swing arm, the two ends of the first transition pull bar flexibly connect with the plumbing arm and the first transition swing arm respectively, the rear and front end of the second transition pull bar flexibly connects with the rear end of the first transition swing arm and the second transition swing arm respectively, the front end of the second transition swing arm and the second bridge drag link flexibly connects, and the rear end of the second bridge drag link and second propons flexibly connect.
