Abstract
The utility model relates to a steel plate spring support with a composite function and applicable to an outside-turning vehicle frame. The support is composed of a support body and an auxiliary connection structure and is characterized in that the support body is of a casing structure recessed backwards. The lateral side of the auxiliary connection structure is n-shaped, a front arm of the auxiliary connection structure is longer than a back arm of the auxiliary connection structure, a support pin hole is arranged in the middle section of the front arm of the auxiliary connection structure, a support pin hole is arranged on the back arm of the auxiliary connection structure, the support pin holes of the front arm and the back arm of the auxiliary connection structure are coaxial, the position of the front support pin hole of the front arm of the auxiliary connection structure is an inclined face, and the back of the back arm of the auxiliary connection structure is of a closed rib structure, a pin hole is arranged at the lower end of the front arm, the support body and the auxiliary connection structure are of an integral structure, and the support body is located above the auxiliary connection structure. The pulled side of the support is of a casing structure, so that the spring support has better performance compared with a rib structure support, reduces stress concentration, improves reliability, prolongs service life and reduces maintenance and replacement times for users. The support is of a composite structure, part utilization ratio is improved, and the aims of saving space and reducing weight are achieved for a whole vehicle. The pin hole position of the support is of an inclined face structure, so that assembly of steel plate spring pins is facilitated. The outer side of the pulled side of the support is of a closed rib structure, and durability is high.
Description
Technical field
The utility model relates to a kind of complex function spring carrier that is applicable to the vehicle frame that turns up, and belongs to the technical field of commercial vehicle/comm..vehicle suspension system, particularly connects the spring carrier of turn up vehicle frame and steel plate spring assembly in a kind of suspension system.
Background technology
At present, in the Leaf Spring Suspension System of commercial vehicle/comm..vehicle field widespread use, generally all be to adopt spring carrier to be connected between vehicle frame and the steel plate spring assembly, so the reliability of spring carrier and durability have very significant effects to user's traffic safety.And current one of them key factor that influences spring carrier service life is the design of supporting structure.
At present, the spring carrier structure of overturning frame in multiple being applicable to has been arranged, and similar patented product has also been arranged.And along with the development of car load configuration, interior overturning frame can't satisfy the car load configuration to the requirement in space, and the body frame structure for automotive that occurs turning up, arising at the historic moment the spring carrier structure of the vehicle frame that turns up occurred adapting to.In order to improve the effective rate of utilization of parts, design a kind of spring carrier with complex function simultaneously.Traditional spring carrier structure design form mostly is reinforcing rib structure basically, and the reinforced rib compressive property of this Foundry Production is good, but tension not.Cause often taking place in the vehicle use spring carrier for above-mentioned reasons and crackle occurs, even the situation of fracture.
And this complex function spring carrier of the vehicle frame that turns up that is applicable to integrates multiple function, has not only improved the degree of utilization of part, and adopts shell construction, and intensity is higher, and better reliability has promoted service life of part.
Summary of the invention
The purpose of this utility model provides a kind of complex function spring carrier that is applicable to the vehicle frame that turns up, its support tension face is shell construction, and is better than muscle structure stand performance, improves stress and concentrates, improve reliability and the service life thereof of support, reduced the frequency that the user safeguards replacing; Support is composite structure, improves the parts degree of utilization, namely saves the space and can reach the purpose of falling weight again for car load; Support pin-and-hole place beveling structure, leaf spring pin convenient for assembly; Enclosed shape muscle structure, durability height are made in the support tension face outside.
The technical solution of the utility model is achieved in that a kind of complex function spring carrier that is applicable to the vehicle frame that turns up, by rack body, auxiliary connection structure is formed, it is characterized in that: the shell construction of rack body for caving in backward, auxiliary connection structure side is " n " type, its forearm is than back brachium, auxiliary connection structure forearm stage casing has the support pin-and-hole, auxiliary connection structure postbrachium also has the support pin-and-hole, auxiliary connection structure forearm is coaxial with the support pin-and-hole of postbrachium, the front support frame pin-and-hole position of auxiliary connection structure forearm is the inclined-plane, the back side of auxiliary connection structure postbrachium is enclosed shape muscle structure, the forearm lower end has pin-and-hole, rack body and auxiliary connection structure are one-piece construction, and rack body is positioned at auxiliary connection structure top.
Good effect of the present utility model is that its support tension face is shell construction, and is better than muscle structure stand performance, improves stress and concentrates, improve reliability and the service life thereof of support, reduced the frequency that the user safeguards replacing; Support is composite structure, improves the parts degree of utilization, namely saves the space and can reach the purpose of falling weight again for car load; Support pin-and-hole place beveling structure, leaf spring pin convenient for assembly; Enclosed shape muscle structure, durability height are made in the support tension face outside.
