Abstract
The utility model provides a lateral rod suspension in order to improve the bending resistant performance of lateral rods and the buffering performance of the suspension and to avoid suspension local failure caused by uneven stress. The lateral rod suspension comprises lateral rods, a rear axle and two dragging arms which are fixed at the two ends of the rear axle through bushing bases. The lateral rod suspension is characterized in that the lateral rods are symmetrical with each other, the number of the lateral rods is two, the front end of each lateral rod is connected with one dragging arm on the corresponding side of the lateral rod, and the rear end of each lateral rod is connected with a vehicle body. Two left-right symmetrical rod structures are adopted in the lateral rods, a traditional single-rod pulling rod mode is replaced, the problem of pressing rod instability caused by the long rods easily is solved, the suspension local failure caused by uneven stress is avoided, furthermore, the length and the arrangement angle of the lateral rods can be adjusted conveniently according to the movement trails and the mounting angles of a suspension main elastic component and a shock absorber, and the buffering performance is improved.
Description
Technical field
The utility model belongs to automotive field, relates to a kind of suspension frame structure.In particular, the utility model relates to a kind of horizontal thrust rod-type suspension.
Background technology
Automotive suspension can be divided into independence and two kinds of modes of dependent suspension.Briefly, between the wheel of two of left and right, do not have hard axle to connect, in the situation that the sprung parts of one-sided wheel is all only connected with vehicle body, can be defined as independent suspension; It is not independently that dependent suspension refers between two wheels, has rigid connection thing, and can cause mutual interference between the wheel of both sides.The front suspension of most manned vehicles is all independent suspension, and rear suspension is had nothing in common with each other.Lateral rod suspension is dependent suspension form common in rear suspension, and it is simple in structure, can obtain better rigidity and crossing ability.In general horizontal thrust rod-type rear suspension, lateral rod is the non-symmetrical rod member in left and right, and one end, two ends, left and right is connected with suspension, and the other end is connected with vehicle body.The lateral rod suspension frame structure of this form can bring following problems: 1, with a rod member, connect two ends, left and right and will certainly cause rod member long, and the Main Function of lateral rod is to share the vehicle body side force of automobile in the situations such as turning, the long words of lateral rod easily cause propelling rod bending deformation; 2, the two ends, left and right that conventionally connect the single lateral rod at two ends, left and right are that lining connects, and this structure is not obvious for the cushion characteristic that increases suspension, is mainly to cushion by spring; 3, the propelling rod of common lateral rod suspension is the non-symmetrical rod member in left and right, and this rod member, for symmetrical suspension, can cause the unbalance stress of suspension, and serious words can cause the local failure of suspension.
Summary of the invention
The purpose of this utility model is to propose a kind of lateral rod suspension, to improve the anti-flexural property of lateral rod and the cushion characteristic of suspension, and avoids the inhomogeneous stressed suspension local failure causing.
Lateral rod suspension of the present utility model comprises lateral rod, rear axle and by liner clamp, is fixed on two towing arms at rear axle two ends, key is that described lateral rod is for two of symmetry, the front end of every lateral rod is connected with the towing arm of respective side, and rear end is connected with vehicle body.
Above-mentioned lateral rod adopts two symmetrical member structures, has replaced traditional single pole part propelling rod form, has avoided, because of the long strut buckling problem easily causing of rod member, having avoided the inhomogeneous stressed suspension local failure causing.And can according to the path of motion of the main elastic element of suspension and shock absorber and setting angle, adjust easily length and the layout angle of lateral rod, improve cushion characteristic.
Further, the cross section of described lateral rod is opening trough_like, effectively raises bending resistance and the anti-flexural property of lateral rod.
Further, the front end of described lateral rod is provided with lining; The rear end of described towing arm is provided with a bolt shank, and described bolt shank passes the inner sleeve of described lining and is threaded with inner sleeve.Lateral rod is connected with towing arm by lining, can play certain positive role to improving the cushion characteristic of suspension.
Further, the rear end of described lateral rod is welded with lining, and described lining is provided with support by bolt, the both sides of described support are with flange, described flange is provided with bolt hole, and described support is connected with body bolt by the bolt hole of two side flangings, is convenient to Assembly &Disassembly.
Lateral rod suspension frame structure of the present utility model is simple, and anti-song and buffering effect are obvious, and cost is lower, is easy to realize, and is convenient to Assembly &Disassembly in production, has good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of lateral rod suspension of the present utility model.
Fig. 2 is the A-A schematic cross-section of lateral rod.
In figure: 1, rear axle; 2, towing arm; 3, liner clamp; 4, propelling rod; 5, bolt shank; 6, support; 7, lining.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and principle of work etc.
Embodiment 1:
As shown in Figure 1, 2, the lateral rod suspension of the present embodiment comprises lateral rod 4, rear axle 1 and by liner clamp 3, is fixed on two towing arms 2 at rear axle two ends, key is two that described lateral rod 4 is symmetry, the front end of every lateral rod 4 is connected with the towing arm of respective side 2, and rear end is connected with vehicle body.
Specifically, the front end of lateral rod 4 is provided with lining 7, and the sleeve of lining 7 is directly welded on the end of propelling rod 4; The rear end of towing arm 2 is provided with a bolt shank 5, and described bolt shank 5 passes the inner sleeve of described lining 7 and is threaded with inner sleeve.Lateral rod 4 is connected with towing arm 2 by lining 7, can play certain positive role to improving the cushion characteristic of suspension.
The rear end of lateral rod 4 is welded with lining 8, described lining 8 is provided with support 6 by bolt, and the both sides of described support 6 are with flange, and described flange is provided with bolt hole, described support 6 is connected with body bolt by the bolt hole of two side flangings, is convenient to Assembly &Disassembly.
For improving bending resistance and the anti-flexural property of lateral rod 4, the cross section of lateral rod 4 is opening trough_like, is specifically of a size of: wide 20mm, and high 10mm, thickness is 3mm.
Above-mentioned lateral rod 4 adopts two symmetrical member structures, has replaced traditional single pole part propelling rod form, has avoided, because of the long strut buckling problem easily causing of rod member, having avoided the inhomogeneous stressed suspension local failure causing.And can according to the path of motion of the main elastic element of suspension and shock absorber and setting angle, adjust easily length and the layout angle of lateral rod, improve cushion characteristic.
