Technical field
The utility model relates to the compound rear-suspension system of a kind of rubber auxiliary spring, belongs to the technical field of commercial vehicle/comm..vehicle suspension system designs, particularly a kind of NEW TYPE OF COMPOSITE rear-suspension system that utilizes the rubber auxiliary spring to replace steel spring auxiliary spring and bump rubber.
Background technology
For traction or loading commercial vehicle/comm..vehicle and since rear-suspension system empty, the at full load load change is bigger, considers the ride comfort requirement, major and minor two-stage variable-rate suspension system is widely adopted when the coupling design of rear suspension.At present used major and minor two-stage variable-rate suspension system mainly is divided into two kinds: major and minor split type and major and minor integral type.But domestic commercial vehicle/comm..vehicle adopt major and minor spring structure suspension system, auxiliary spring is the steel spring structure, on jump spacing by the coupling damping rubber block finish.Only there is a spot of suspension system to adopt rubber auxiliary spring structure in North America market at present, also is mainly used in the less load-carrying vehicle of load.
Mainly there is following problem in this structure:
1) the used material of major and minor spring is spring steel, and weight is heavier;
2) whole suspension system can only realize that two-stage becomes rigidity (i.e. unloaded and fully loaded two kinds of stiffness variation);
3) when the wheel bob, because auxiliary spring and the collision of auxiliary spring support can produce certain noise;
4) jump the stop gear that needs increase extra on the suspension system, increased the suspension system amount of parts, strengthened assembling intensity simultaneously;
5) because stiffness variation is unexpected, traveling comfort is bad.
The purpose of this invention is to provide a kind of novel suspension system.Can address the above problem, meet the energy conservation and environment protection to vehicle simultaneously.
Summary of the invention
The purpose of this utility model provides the compound rear-suspension system of a kind of rubber auxiliary spring, it utilizes a kind of rubber auxiliary spring that can satisfy the large deformation function to replace original steel spring auxiliary spring, by support this rubber auxiliary spring is fixed on the vehicle frame side, the weight of suspension system is reduced about 80kg, played the energy-conserving and environment-protective effect, this rubber auxiliary spring is in certain deformation range, stiffness variation is soft, can guarantee the traveling comfort of suspension system in conventional range of use, and the noise that produces when having avoided metal and metal bump; This auxiliary spring stiffness variation when large deformation is violent simultaneously, plays position-limiting action, so can cancel conventional bump rubber.
The technical solution of the utility model is achieved in that the compound rear-suspension system of a kind of rubber auxiliary spring, by vehicle frame, main steel plate spring front frame, the main steel plate spring, rubber auxiliary spring support, the rubber auxiliary spring, tie bolt, the main steel plate spring back rest, locking pin, bearing pin, lock bolt, suspension ring, clevis bolt, nut, lower cover, upper cover plate is formed, it is characterized in that: the rubber auxiliary spring is captiveed joint with rubber auxiliary spring support, rubber auxiliary spring support is captiveed joint with vehicle frame by tie bolt, main steel plate spring one end forms axle by bearing pin and main steel plate spring front frame and connects, then by the locking pin fixed pin shaft; Main steel plate spring front frame is captiveed joint with vehicle frame, the main steel plate spring other end forms axle even by an end of bearing pin and suspension ring, then by the lock bolt fixed pin shaft, the other end of suspension ring forms axle by bearing pin and main steel plate spring back rest and connects, and the main steel plate spring back rest is fixedly connected on the vehicle frame; The middle upper part of main steel plate spring has upper cover plate to fix by clevis bolt, there is lower cover the below in the middle of the main steel plate spring, lower cover is fixed with steel spring and back axle by clevis bolt and nut, and the midway location of main steel plate spring is vertical coaxial with the fixed position of rubber auxiliary spring.
Described rubber auxiliary spring integral body is ellipsoidal structure, and inside is cavity structure; Two coupling nuts in cavity structure bottom and the sulfuration of rubber auxiliary spring.
Good effect of the present utility model is to reduce 6 of parts and assembly quantity, can realize falling heavy 80kg/ car at most.
Description of drawings
Fig. 1 is constructional drawing of the present utility model.
Fig. 2 is rubber auxiliary spring constructional drawing of the present utility model.
Fig. 3 is rubber auxiliary spring load-displacement curve figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further: as Fig. 1, shown in 2, the compound rear-suspension system of a kind of rubber auxiliary spring, by vehicle frame 1, main steel plate spring front frame 2, main steel plate spring 3, rubber auxiliary spring support 4, rubber auxiliary spring 5, tie bolt 6, main steel plate spring back rest 7, locking pin 8, bearing pin 9, lock bolt 10, suspension ring 11, clevis bolt 12, nut 13, lower cover 14, upper cover plate 15 is formed, it is characterized in that: rubber auxiliary spring 5 is captiveed joint with rubber auxiliary spring support 4, rubber auxiliary spring support 4 is captiveed joint with vehicle frame 1 by tie bolt 6, main steel plate spring 3 one ends form axle by bearing pin 9 with main steel plate spring front frame 2 and connect, then by locking pin 8 fixed pin shafts 9; Main steel plate spring front frame 2 is captiveed joint with vehicle frame 1, main steel plate spring 3 other ends connect by the end formation axle of bearing pin 9 with suspension ring 11, then by lock bolt 10 fixed pin shafts 9, the other end of suspension ring 11 forms axle by bearing pin 9 with main steel plate spring back rest 7 and connects, and main steel plate spring back rest 7 is fixedly connected on the vehicle frame 1; The middle upper part of main steel plate spring 3 has upper cover plate 15 fixing by clevis bolt 12, there is lower cover 14 below in the middle of the main steel plate spring 3, lower cover 14 is fixed with steel spring 3 and back axle by clevis bolt 12 and nut 13, and the midway location of main steel plate spring 3 is vertical coaxial with the fixed position of rubber auxiliary spring 5.
