Referring to fig. 2, a disconnected type balance suspension according to an embodiment of the present invention includes: two balance shaft brackets 1 and a balance shaft cross beam 3. The two balance shaft brackets 1 are each fixedly connected to the frame rail 2 in any suitable manner for supporting a balance shaft (not shown). In the disconnected type balance suspension structure, the balance shafts are disconnected type balance shafts, and each balance shaft bracket 1 supports one balance shaft. Advantageously, the balance shaft 10 is integrally formed with the balance shaft bracket.
Two balance shaft brackets 1 are connected to the frame rail 2 at the left and right outer sides of the frame rail 2, respectively. Specifically, the connection of the balance shaft bracket 1 and the frame rail 2 is achieved by using bolts and nuts that pass through the balance shaft bracket 1 and the frame rail 2. Blind hole threads are eliminated, thereby improving installation strength and reducing manufacturing costs. The balance shaft support is assembled on the outer side of the frame, so that the arrangement space of pipelines in the longitudinal beam is reserved, the arrangement of the pipelines is simplified, the space is reserved for the arrangement of the pipelines, and the problem of difficult arrangement of the pipelines is solved.
The balance shaft beam 3 is a frame structure which is integrally cast. The balance shaft beam structure is changed into the integrally cast beam, so that the rigidity and the torsion resistance of the beam are structurally improved, and the reliability of the whole vehicle is improved. The balance shaft cross member 3 is provided inside the frame rail 2. The two frame longitudinal beams are groove-shaped beams which are arranged opposite to each other in opening. The balance shaft bracket 1 and the balance shaft cross member 3 are fixedly connected to the frame rail 2 by common bolts 5 passing through the balance shaft bracket 1, the web of the frame rail 2 and the balance shaft cross member 3 in order. Advantageously, in addition to the common bolts 5, there are further bolts through the balance shaft bracket 1 and the frame rail 2 to further increase the connection strength of the balance shaft bracket 1 and the frame rail 2.
The balance beam 3 is arranged offset downwards relative to said frame rail 2, forming a pipeline channel 9 located both inside the frame rail 2 and above said balance beam 3. This allows for the provision of a pipeline inboard of the frame rail without the need to bypass the pipeline as in the prior art. Furthermore, the space between the upper stringer wing plate and the upper part of the balance shaft cross member 3 can provide good protection for the pipeline.
As shown in fig. 2, a thrust rod connection seat 36 is provided on the balance shaft beam 3 for connection with the open end of the V-shaped thrust rod. Specifically, four groups of thrust rod connecting seats 36 are arranged on the balance shaft cross beam 3, and every two groups of thrust rod connecting seats 36 are connected with the opening end of one V-shaped thrust rod. Since the open ends of the V-shaped thrust rods are connected to the same member, not to two members (i.e., the two balance shaft brackets 1) as in the prior art. Thus, the distance between the two sets of thrust rod attachment seats 36 for the open end of a single V-shaped thrust rod has better consistency and stability. In the prior art, two balance shaft brackets 1 are connected to the left and right longitudinal beams respectively, and two balance shaft brackets are respectively provided with a group of thrust rod connecting seats, so that the distance between the two groups of thrust rod connecting seats is influenced by the installation accuracy of the balance shaft brackets 1, and under the condition that the consistency of the distance between the left and right longitudinal beams is not very good, the open ends of V-shaped thrust rods cannot be smoothly installed even under partial conditions, and the installation can be realized only by on-site drilling processing. The structure of the invention well overcomes the problems of the prior art.
As shown in fig. 2 and 3, the balance shaft cross member 3 includes a top plate 31, a left side plate 32, a bottom plate 33, and a right side plate 34 connected in sequence in a closed loop shape, and a reinforcing plate 35 located at the middle of the balance shaft cross member 3 and vertically connecting the top plate 31, the left side plate 32, the bottom plate 33, and the right side plate 34. At the middle of the reinforcement plate 35, a line perforation 37 is provided. The line perforation 37 may be used as a supplement to the line passage described above. It should be noted that the illustrated balance shaft beam 3 is illustrative, and the present invention is not limited to the illustrated structure. For example, it is advantageous that the balance shaft cross member 3 has a larger width at both left and right ends to increase the mating and connecting surfaces with the frame rail; and has a smaller width in the middle to reduce the weight of the balance beam 3 as much as possible.
Advantageously, a plurality of reinforcing ribs may be provided on the balance shaft side member 3 to increase the strength of the balance shaft cross member. In particular, longitudinal ribs parallel to the vehicle front direction may be provided on the upper side of the roof panel 31 and the lower side of the floor panel 33 of the balance shaft side member 3. Further, weight-reducing process holes may be provided on each plate of the balance shaft side member 3 to further reduce the weight of the balance shaft side member 3.
In a preferred embodiment, the thrust rod connection seats 36 are provided on the reinforcement plate 35 and/or the left and right side plates 32, 34. The thrust rod connecting seat 36 and the balance shaft cross beam 3 are integrally formed, and an assembly surface of the thrust rod connecting seat 36 for connecting the V-shaped thrust rod is formed by machining. In an alternative embodiment, each set of thrust rod attachment seats 36 includes two attachment points, one attachment point being provided on the reinforcement plate 35 and the other attachment point being provided on the adjacent left or right side plate. Thus, the stress is more uniform.
Preferably, the installation threaded holes arranged on the balance shaft bracket 1 adopt an independent built-in steel wire thread sleeve structure. The mounting screw holes are not mounting holes for connecting the balance shaft bracket 1 to the frame rail, but are used for mounting the plate spring seat 4 or other member to the balance shaft bracket 1. Therefore, tapping on the balance shaft bracket is not needed, so that the whole bracket is required to be replaced or re-tapped for maintenance when the threads are damaged. That is, the screw hole on the balance shaft bracket adopts an independent steel wire thread sleeve structure, so that the problem that the whole bracket is required to be replaced or the maintenance of tapping again is difficult when the screw thread of the bracket is damaged is solved.
The steel wire thread sleeve, also called thread sleeve, is a new type screw fastener, which is a spring-shaped concentric body of internal and external threads formed by precisely processing stainless steel wires with diamond-shaped cross sections with high strength, high precision and smooth surfaces. The steel wire thread insert is an insert developed for protecting the metal threaded hole, is screwed into and fastened in the threaded hole of one of the connected pieces to form an internal thread conforming to the international standard, is similar to a spiral spring in shape, and has higher hardness and better surface roughness. The steel wire thread insert is embedded into the threaded hole of low-strength engineering materials such as aluminum, magnesium alloy, cast iron, glass fiber reinforced plastic, plastic and the like, can form standard M threads, has the functions of high connection strength, shock resistance, impact resistance and wear resistance, can disperse stress to protect the threads of the matrix, and greatly prolongs the service life of the matrix. The invention preferably adopts a locking type steel wire screw sleeve.
Advantageously, the spring plate and balance shaft bracket combination is supplied to simplify the suspension system assembly process.
Referring to fig. 2, connecting plates 8 are respectively provided at lower portions of the two balance shaft brackets 1, and the two connecting plates 8 are connected to each other through a hydraulic damper 7. The hydraulic shock absorber 7 is used to dampen or dampen vibrations of the disconnected balanced suspension, especially when subjected to lateral forces and associated torque. Specifically, the connection plates 8 are detachably connected to the balance shaft bracket 1, and both ends of the hydraulic damper 7 are detachably connected to the respective connection plates 8, respectively. Advantageously, the hydraulic damper 7 is a damping-adjustable damper.
In an alternative embodiment, the center-to-center leaf spring distance of the disconnected balanced suspension at the rear axle is greater than the center-to-center leaf spring distance at the front axle. Therefore, the space between the U-shaped bolt at the rear part and the frame is larger, and the U-shaped bolt can be assembled conveniently. While increasing roll stability of the rear suspension. Advantageously, the rearward limit of the leaf spring is adjusted to limit the spring seat of the axle closure plate to reduce the length of the rear spring.
Specifically, the leaf springs of the disconnected type balance suspension are disposed obliquely in the front-rear direction such that the center distance of the leaf springs gradually increases from front to rear. Of course, other ways or structures may be used to make the center-to-center leaf spring spacing of the split counter-suspension greater at the rear axle than at the front axle. It should be noted that the rear axle and the front axle are referred to herein with respect to two axles (also referred to as axles) to which the split balanced suspension is connected. In practice, the front axle here will be the center axle of a three axle vehicle.
In an alternative embodiment, the open end (large end) of the V-shaped thrust rod is configured as a knuckle bearing with a grease nipple lubrication channel. This is advantageous in reducing the failure rate of the V-shaped thrust rod. The joint bearing has a simpler structure than a rolling bearing and mainly comprises an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. The sliding surface of the knuckle bearing is spherical, and can also perform tilting motion (namely aligning motion) within a certain angle range, and the knuckle bearing can still work normally when the supporting shaft and the shaft housing hole have large concentricity. The knuckle bearing can bear larger load, in particular radial load, axial load or combined load of radial and axial simultaneously. The requirement on installation precision is reduced, and the requirement on the installation precision is adapted to the complex stress condition of the V-shaped thrust rod.
Advantageously, in the spherical plain bearing arrangement, the outer spherical surface of the inner ring is lined with a composite material, so that the bearing is self-lubricating during operation. The device is generally used for swinging movement with lower speed and low-speed rotation, and can also perform tilting movement within a certain angle range, and when the concentricity of the supporting shaft and the shaft housing hole is larger, the device can still work normally.
The present invention also provides a multi-axle vehicle including a first axle (front axle) at the front, a second axle (middle axle) at the middle and a third axle (rear axle) at the rear, and a disconnected balanced suspension. The disconnected balance suspension is any of the disconnected balance suspensions described above. The disconnected balanced suspension connects the second and third axles. The disconnected balance suspension is provided with two V-shaped thrust rods, the opening end of one V-shaped thrust rod is connected with the balance shaft cross beam 3 of the disconnected balance suspension, and the other end of the V-shaped thrust rod is hinged with the second bridge; the open end of the other V-shaped thrust rod is connected with the balance shaft cross beam 3 of the disconnected balance suspension, and the other end of the other V-shaped thrust rod is hinged with the third bridge.
In the disconnected type balance suspension of the present invention, a balance shaft bracket 1 is connected to a frame rail 2 at the left and right outer sides of the frame rail 2, and a balance shaft cross member 3 is arranged downward with respect to the frame rail 2, thereby forming a pipeline passage 9 located at the inner side of the frame rail 2 and above the balance shaft cross member 3 at the same time; the disadvantage of requiring a pipeline to bypass the balanced suspension is avoided. In addition, a thrust rod connection seat 36 is provided on the balance shaft beam 3 for connection with the open end of the V-shaped thrust rod. Therefore, the opening ends of the V-shaped thrust rods are connected to the same component, but not to the left and right balance shaft brackets, so that the installation of the V-shaped thrust rods is prevented from being influenced by the consistency of the width of the frame.
Finally, it should be pointed out that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting. Those of ordinary skill in the art will appreciate that: the technical schemes described in the foregoing embodiments may be modified or some of the technical features may be replaced equivalently; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
