Abstract
The utility model discloses an oil cylinder driven steering axle device for a motor vehicle, relating to the technical field of vehicles. The oil cylinder driven steering axle device comprises a steering axle I beam and a lateral tension bar of which two ends are respectively connected with the lower arm of a steering section, wherein the steering axle I beam is connected with a steering oil cylinder and a moving end of the steering oil cylinder is connected with the lateral tension bar of a steering axle. Compared with the prior art, the steering axle device has the advantages that the steering synchronism and coordination of a rear steering axle and a front steering axle are stable, the performance is reliable and the structure is simple.
Description
Technical field
The utility model relates to the hydraulic oil cylinder driving motor turning Biodge device that a kind of automobile is used for vehicle.
Background technology
Vehicle multiple-shaft turns to have and improves vehicle handling and stability and steering flexibility, minimizing wear on tyres, reduces advantage such as minimum turning radius, is the development tendency and the direction of heavy amount, multiple-axle vehicle.At present, mechanical steering or mechanical-hydraulic servo-steering are generally adopted in the rear axle steering of multiple-axle vehicle, and (see figure 1) promotes plumbing arm 2 through steering side tube 1, and another longitudinal tie 4 promotion steering swivel upper arm 6 realization rear axle steerings of plumbing arm 2 lower ends connection and front-axle steering are synchronous.Power-assisted oil cylinder 3 one ends are connected with main car frame, and the other end is connected with plumbing arm 2, as the auxiliary power that turns to; Because the variation of gross vehicle weight and the variation of the road conditions of going; Steering swivel upper arm 6 is on steeraxle, and along with the relative main car frame of steeraxle moves up and down, the angle of longitudinal tie 4 changes makes steering swivel upper arm 6 generations that are attached thereto turn to displacement; Steering swivel upper arm 6 promotes steered wheels 5 and turns to, destroyed turn to back axle and front steering axle turn to synchronously and turn to harmony.
Summary of the invention
The utility model provides a kind of hydraulic oil cylinder driving motor turning Biodge device, it can solve prior art turn to back axle and front steering axle turn to synchronism and to turn to harmony unstable, the insecure problem of performance.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: it includes the lateral pull bar that steeraxle H-girder and two ends are connected with the steering swivel underarm respectively; Said steeraxle H-girder is connected with and turns to oil cylinder, and this turns to the moved end of oil cylinder to be connected with the lateral pull bar of steeraxle.
In the technique scheme; Scheme is more specifically: described steeraxle H-girder is with described to turn to being connected of oil cylinder can maybe can be that ball pivot connects for bearing pin connects; Describedly turn to being connected of oil cylinder and described lateral pull bar can be for bearing pin connects or can connect by ball pivot, the described oil cylinder that turns to can be that steering jack also can be the power steering oil cylinder.
Because employing technique scheme, the utility model are compared with prior art, the advantage that has is to turn to turning to synchronism and turning to harmony to stablize of back axle and front steering axle, and dependable performance is simple in structure.
Description of drawings
Fig. 1 is traditional motor turning Biodge device.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing instance the utility model is done further to detail:
The utility model as shown in Figure 2; It includes steeraxle H-girder 2; Steeraxle H-girder 2 stage casings are connected with an end that turns to oil cylinder 4, and this turns to the other end of oil cylinder to be connected with the lateral pull bar 3 of steeraxle, and the two ends of lateral pull bar 3 are connected with the underarm 5 of a steering swivel 1 respectively.Left and right wheels all turns to through the underarm 5 that lateral pull bar 3 promotes steering swivel 1 synchronously, and steeraxle H-girder 2 is connected with the bearing pin that is connected to that turns to oil cylinder 4, turns to oil cylinder 4 to be connected with the bearing pin that is connected to of lateral pull bar 3, turns to oil cylinder 4 that steering power is provided.
