Description
Technical field
The utility model relates to car chassis field, especially a kind of front steering axle servo-steering structure.
Background technology
At present, the front steering axle using on light truck, generally adopts the beam structure of central siphon spindle nose assembly welding, and this structure is not all with hydraulic power-assisted steering mechanism at present.Owing to lacking corresponding servo-steering structure, while turning to, to be applied to hand-power on steering handwheel just larger for chaufeur, and the safety of therefore travelling in the time of actual travel and traveling comfort are all not too high.The how economical and effective servo-steering of realizing is also that there is problem to be solved in each auto vendor at present.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of more labour-saving and realizes the front steering axle servo-steering structure that front steering axle turns to.
The utility model solves the technical scheme that its technical matters adopts: front steering axle servo-steering structure, comprise axletree, be arranged at the wheel hub at described axletree two ends, be respectively used to the left tie rod arm and the right tie rod arm that drive described two wheel hubs to rotate, also comprise hydraulic ram and tie rod arm pipe link, the two ends of tie rod arm pipe link are articulated with respectively left tie rod arm and right tie rod arm, one end and the support tube of described hydraulic ram are rotatably connected, described support tube is fixedly installed on axletree, the other end of hydraulic ram is articulated with on the oil cylinder hinge-point of tie rod arm pipe link.
Further, described support tube is fixedly installed on the axletree stage casing of axletree.
Further, the right tie rod arm hinge-point between the oil cylinder hinge-point of described tie rod arm pipe link and tie rod arm pipe link and right tie rod arm is close to.
Further, described hydraulic ram is double-acting type hydraulic ram.
The beneficial effects of the utility model are: first the utility model has set up hydraulic ram, provide extra propulsive effort when turning to, have reduced chaufeur and have been applied to the hand-power on steering handwheel.Meanwhile, the utility model has also designed and left tie rod arm and the hinged tie rod arm pipe link of right tie rod arm cleverly, ensure that hydraulic ram is in the time driving tie rod arm pipe link, the turning effort of left tie rod arm and right tie rod arm is all more even, thus allow turn to more smooth-going.The utility model is particularly useful in manufacture that the front steering axle of light truck turns to.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, be labeled as: axletree 1, axletree stage casing 11, left tie rod arm coupling end 12, right tie rod arm coupling end 13, wheel hub 2, hydraulic ram 3, support tube 31, oil cylinder hinge-point 32, tie rod arm pipe link 4, left tie rod arm 41, left tie rod arm hinge-point 411, right tie rod arm 42, right tie rod arm hinge-point 421.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Front steering axle servo-steering structure as shown in Figure 1, comprise axletree 1, be arranged at described axletree 1 two ends wheel hub 2, be respectively used to the left tie rod arm 41 and the right tie rod arm 42 that drive described two wheel hubs 2 to rotate, also comprise hydraulic ram 3 and tie rod arm pipe link 4, the two ends of tie rod arm pipe link 4 are articulated with respectively left tie rod arm 41 and right tie rod arm 42, one end of described hydraulic ram 3 and support tube 31 are rotatably connected, described support tube 31 is fixedly installed on axletree 1, and the other end of hydraulic ram 3 is articulated with on the oil cylinder hinge-point 32 of tie rod arm pipe link 4.
In the time of actual making, due to the space constraint of the front steering axle using on light truck, the utility model is fixed on by support tube 31 hydraulic ram 3 that assist function is provided on axletree 1 flexibly.As shown in Figure 1, such mode not only can rationally be utilized space, also can ensure that the propulsive effort that hydraulic ram 3 applies is evenly reasonably assigned on left tie rod arm 41 and right tie rod arm 42 by tie rod arm pipe link 4, finally ensures the deflection of wheel hub 2.In conjunction with shown in Fig. 1, the utility model has the advantage of: one, realized power-steering function; The layout of the hydraulic ram 3 two, increasing is more ingenious, has ensured near making full use of of axletree 1 vacant space.
In the time of actual fabrication, in order to ensure the stressed optimization between support tube 31 and hydraulic ram 3, can select described support tube 31 to be fixedly installed on the axletree stage casing 11 of axletree 1.As shown in Figure 1, the such layout of support tube 31 can allow stretching of hydraulic ram 3 more reasonable, is also that the space of left tie rod arm coupling end 12 and right tie rod arm coupling end 13 is more abundant simultaneously, thereby has ensured the space needing when wheel hub 2 turns to.
For the effect to tie rod arm pipe link 4 of the propulsive effort of optimizing hydraulic ram 3, can select the right tie rod arm hinge-point 421 between the oil cylinder hinge-point 32 of described tie rod arm pipe link 4 and tie rod arm pipe link 4 and right tie rod arm 42 to be close to.As shown in Figure 1, oil cylinder hinge-point 32 is close to right tie rod arm hinge-point 421, can allow the propulsive effort of hydraulic ram 3 directly better drive tie rod arm pipe link 4 along the direction that is almost parallel to tie rod arm pipe link 4, allow propulsive effort be utilized more fully, also allow left tie rod arm hinge-point 411 and right tie rod arm hinge-point 421 more reasonable, prevented the component perpendicular to tie rod arm pipe link 4 directions simultaneously.
In view of the mode of operation of hydraulic ram 3 reality, in the time choosing hydraulic ram 3, preferably hydraulic ram 3 is double-acting type hydraulic ram.Because hydraulic ram 3 needs to realize the driving to tie rod arm pipe link 4 by " stretching " or " contracting ", in order to make the propulsive effort of above-mentioned both direction all more even, can select to utilize the symmetry of double-acting type hydraulic ram in the time of bidirectional-movement, thereby ensure no matter wheel hub 2 is toward which direction rotation, and the propulsive effort of its rotation is identical.
