The structure form enables the rubber spring on the bridge and the middle rubber spring to form a two-stage series connection relationship, and the series connection relationship does not increase the total height dimension additionally, so that the whole structure of the invention is very compact.
In the embodiment of the invention, the balance swing arm can swing relative to the automobile body, and the swinging freedom degree of the balance swing arm is realized by two modes: the first mode is realized by the distortion of the middle position rubber spring; the second mode is realized by the assembly relationship shown in fig. 9 of the rotating sleeve, the bearing and the rotating shaft.
Referring to fig. 8 and 9, in the embodiment of the present invention, a through hole for connecting the rotating shaft 80 is provided on the second fixing portion 102; a bearing 801 is arranged inside the rotating shaft 80, and a rotating shaft sleeve 802 is sleeved outside the rotating shaft 80; the outer side of the rotating shaft sleeve 802 is provided with a middle position rubber spring support 201 for connecting a middle position rubber spring 20.

Wherein, the rubber spring 40 on the bridge adopts a composite structure that metal and rubber are vulcanized into a whole. The upper and lower metal plates are used as the connecting surface, and the middle of the rubber body can be coated with a spiral spring.
In the embodiment of the invention, a frame connecting bracket 10 is connected with an automobile beam 60 through bolts or rivets, the frame connecting bracket 10 is welded or connected with a rotating shaft 80 through bolts, rubber springs on a bridge are respectively arranged on each side of each axle, a bolt connecting hole is processed on a flange plate at the bottom of the rubber springs, and the rubber springs are connected with a mounting surface on an axle shell through bolts; the impact from the road surface is transferred first to the spring via the tire and axle, resulting in a first most direct level of cushioning.
The top flange plate of the rubber spring 40 on the bridge is also provided with a bolt connecting hole which is connected with one side of the balance swing arm through a bolt; after the impact energy is absorbed by the primary spring, the rest impact force is transmitted to the balance swing arm.
The balance swing arm is not rigidly connected with the automobile beam, a middle rubber spring is arranged in the middle of the balance swing arm, and the middle rubber spring absorbs the residual impact force transmitted by the balance swing arm for the second time; the energy is absorbed through the buffering of the two-stage rubber spring, so that the impact of the road surface on the vehicle body is reduced.
The balance swing arm can swing relative to the automobile body, and the swinging freedom degree of the balance swing arm is realized by two modes: the first mode is realized by the distortion of a middle rubber spring; the second mode is realized by an assembly of the rotating shaft sleeve, the bearing and the rotating shaft. The free swing of the balance swing arm is very important for an automobile chassis, the driving force is reduced when the automobile wheels float, and the axle load is transferred and concentrated to local wheels and an axle, so that the bad phenomenon of the wheel float can be effectively avoided by the balance suspension, and when a certain wheel meets a raised barrier and is lifted upwards, the adjacent wheels on the same side are pressed downwards by the balance swing arm through the swing of the balance swing arm so as not to float; similarly, when a certain wheel meets a concave road surface, the adjacent wheels on the same side are forced to lift upwards due to the sudden increase of the load on the bridge, and the wheels above the concave pits are pressed down to be contacted with the concave road surface through the swinging of the balance swing arms, so that the phenomenon that the wheels are emptied is avoided.
The articulated joint at one end of the thrust rod is arranged at the lower side of the axle shell, the articulated joint at the other end of the thrust rod is arranged at the lower side of the balance swing arm, the articulated joint can swing in the direction vertical to the road surface, and the degrees of freedom of other spaces are restricted; the thrust rod rigidly transmits driving force and braking force on one hand, and restricts the motion track of the axle relative to the vehicle body on the other hand, so that the axle can only move in a reasonable calculation range, and the motion interference of a transmission shaft and the interference of the axle and the vehicle body are avoided.
The balance swing arm and the rubber spring on the axle act together to provide motion constraint for the axle, and the final motion range of the axle is ensured under the combined action of the constraint and the thrust rod.
The balance swing arm and the frame connecting bracket can be formed by bending and welding steel plates, so that the small-batch and even single-piece personalized manufacturing is feasible; all parts do not need to be invested in complicated dies or subjected to complicated machining.
The composite rubber is used as an elastic element, and compared with a steel plate spring suspension, a torsion bar spring, an air spring, an oil-gas spring and a spiral spring, the rubber spring is light in weight, low in manufacturing cost and free of maintenance; the comprehensive elastic characteristics of the rubber spring in the stretching direction, the twisting direction and the bending direction are not possessed by other types of springs; the composite rubber part spring is adopted as an elastic element, so that the comfort of the composite rubber part spring is superior to that of the most widely used steel plate spring suspension at present; the rubber spring has the capacity of elastic deformation and elastic recovery in multiple spatial freedom directions, so that the structure of the balance mechanism is simplified, and the number of thrust rods is reduced; the suspension has simple integral structure, light weight and convenient maintenance; the production of very single parts in small batch can be realized without investing in the cost of a mold; the sizes of parts are changed, so that the vehicle models with different loading qualities can be matched, and the research and development period of a new vehicle model is shortened; the device can be quickly connected with a frame of a shaped chassis so as to quickly derive new vehicle types with different wheelbases; other forms of counterbalanced suspension on the vehicle in use can be directly replaced without the need to replace the automotive frame.
The rubber spring on the bridge needs to have enough large compression amount or stretching amount in a limited height range to realize the best effect of absorbing impact energy, and a structural composite material structure formed by vulcanizing a spiral spring and a rubber block into a whole is preferably adopted.
As shown in fig. 13, the middle arm of the thrust rod is in a turning shape to avoid interference with the balance swing arm in the motion trajectory.
