Abstract
The utility model relates to a novel heavy-duty car steering system, comprising a left steering device and a right following device, wherein the left steering device comprises a steering device support, a steering device, a first steering drop arm, a first steering drag link and a steering joint arm on the upper left side of a front bridge; the right following device comprises a following device support, a following device, a second steering drop arm, a second steering drag link and a steering joint arm on the upper right side of the front bridge; and a hydraulic oil path system is arranged between the steering device and the following device. According to the novel heavy-duty car steering system disclosed by the utility model, the following device is added on the conventional steering system, and the hydraulic oil path system is arranged between the steering device and the following device, so that the steering output torque and the steering rigidity of the steering system are improved, and the steering of a whole car is lighter and more convenient and flexible. As the novel heavy-duty car steering system is provided with the steering device and the following device which are symmetrically arranged on the left side and the right side of the system, the steering balance of the car which is turned to left and right is better compared with that of a car with a steering device singly arranged on the left side; and simultaneously, the steering following device has better sealing performance compared with an auxiliary cylinder so as to reduce the oil leakage of the steering system.
Description
Technical field
The utility model relates to a kind of automobile steering system, particularly a kind of novel heavy duty automobile steering system.
Background technology
Automobile steering system is the specialized agency that changes or keep vehicle traveling direction; Automobile can be required according to the manipulation of chaufeur in the process of moving and in time change its travel direction; And when receiving the accidental impact that transmits on the road surface and automobile and all of a sudden depart from travel direction, can cooperate the common automobile that keeps to continue stable going with driving system.Therefore, the performance of steering swivel system directly affects the road-holding property and the safety of automobile.
Some heavy motor vehicle turns to requirement because the front axle axle is heavy excessive only according to borrowing the deflector hydraulic booster can't satisfy car load.In order to improve the car load turning efficiency, mostly existing design is that deflector joins the servo cylinder form, through the servohydraulic cylinder power-assisted, improves the car load steering effort, realizes turning efficiency.But its car load handling maneuver stability, turn to rigidity a little less than.
The utility model content
The purpose of the utility model is in order to overcome the problems referred to above, a kind of novel heavy duty automobile steering system to be provided.
For achieving the above object; The method that the utility model adopts is: a kind of novel heavy duty automobile steering system; Comprise left side deflector device and right side follower device; Said left side deflector device comprises steering gear bracket, deflector, first steering drop arm, first steering drag link and propons left side track arm, and said deflector is installed on the steering gear bracket, is connected through first steering drop arm, first steering drag link and propons left side track arm.Said right side follower device comprises right hand steering joint arm on follower support, follower, second steering drop arm, second steering drag link and the propons; Said follower is installed on the follower support, is connected through second steering drop arm, second steering drag link and propons right hand steering joint arm.Between described deflector and follower, be provided with hydraulic oil pipe system.
As a kind of improvement of the utility model, described left side deflector device and right hand steering apparatus are symmetrical structure.
The beneficial effect of the utility model is:
1, the utility model is through being provided with follower, and between deflector and follower, is provided with hydraulic oil pipe system, and the deflector of identical cylinder diameter cooperates with servo cylinder on year-on-year basis, improves turning to output torque and turning to rigidity of system, makes the more light and flexible that turns to of car load.
2, adopt the steering hardware of the left and right sides, than the steering hardware that is arranged in the left side merely, right-hand turning left to the time steering balance property better.
3, turn to follower better, reduced system's leakage of oil than the sealing property of servo cylinder.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the left side deflector of the utility model;
Fig. 3 is the structural representation of the right hand steering device of the utility model;
Fig. 4 is the hydraulic circuit structural representation of the utility model;
Wherein each parts is:
1 steering gear bracket, 2 deflectors, 3 first steering drop armes, 4 first steering drag links, 5 propons left side track arm, 7 follower supports, 8 followers, 9 second steering drop armes, 10 second steering drag links, 11 propons right hand steerings joint arm.
The specific embodiment
Like the described a kind of novel heavy duty automobile steering system of Fig. 1; Comprise left side deflector device and right side follower device; Said left side deflector device comprises steering gear bracket 1, deflector 2, first steering drop arm 3, first steering drag link 4 and propons left side track arm 5; Said deflector 2 is installed on the steering gear bracket 1, is connected through first steering drop arm 3, first steering drag link 4 and propons left side track arm 5.Said right side follower device comprises right hand steering joint arm 11 on follower support 7, follower 8, second steering drop arm 9, second steering drag link 10 and the propons; Said follower 8 is installed on the follower support 7, is connected through second steering drop arm 9, second steering drag link 10 and propons right hand steering joint arm 11.Between described deflector 2 and follower 8, be provided with hydraulic oil pipe system.
A kind of improvement of the utility model, described left side deflector device and right hand steering apparatus are symmetrical structure.
The utility model is when work, and deflector 2 cooperates with follower 8, mainly through the hydraulic circuit effect between deflector 2 and the follower 8, through the hydraulic oil effect, deflector is cooperated synchronously with follower.When turning to the left, first steering drop arm 3 rotates forward, drives propons left side track arm 5 and rotates forward, make the wheel left-handed turning to.Simultaneously,, second steering drop arm 9 on right side is rotated backward, drive propons right hand steering joint arm 11 and rotate backward, right side wheels is turned left through the hydraulic circuit effect.When turning to the right, principle is identical.
Power steerig pump sucks hydraulic oil, is converted into high pressure oil and flows in the deflector 2, through deflector 2 being driven 3 effects of first steering drop arm.Hydraulic oil through deflector 2 flows in the follower 8 synchronously, and driving changes 9 effects of second steering drop arm, and hydraulic oil flows into deflector by follower at last, gets back in the oil tank.
The utility model is through setting up follower; And between deflector and follower, be provided with hydraulic oil pipe system; The deflector of identical cylinder diameter cooperates with servo cylinder on year-on-year basis, improves turning to output torque and turning to rigidity of system, makes the more steering hardware of the light and flexible employing left and right sides that turns to of car load; Than the steering hardware that is arranged in the left side merely, right-hand turning left to the time steering balance property better.Turn to follower better, reduced system's leakage of oil than the sealing property of servo cylinder.
The above; It only is the preferred embodiment of the utility model; Be not to be the utility model to be done the restriction of any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that the technical spirit of the utility model is done.
