Abstract
The invention provides an automobile plate spring guide arm. A curled lug is arranged upwards at one end of a flat and straight plate spring. The automobile plate spring guide arm is characterized in that a Z-shaped plate spring is arranged downwards at the other end of the flat and straight plate spring and side edges are bent from the bottom edge to the side faces of the Z-shaped plate spring; the side edges are arranged on the two sides of the bottom edge of the Z-shaped plate spring; a supporting arm and the flat and straight plate spring are perpendicular to the bottom edge of the Z-shaped plate spring; and the included angle formed by each side edge and the bottom edge of the Z-shaped plate spring ranges from 30 degrees to 50 degrees and the distance between an air bag installation center position on each side edge and the center of the supporting arm is not larger than 120 mm. By the adoption of the automobile plate spring guide arm, the beneficial effects of the flat and straight plate spring and Z-shaped and side bent type plate spring guide arms are combined, the problems existing in air spring design height and transverse arrangement space are well solved, the mechanical characteristic of a spring steel material is brought into full play, a composite air suspension structure is simplified, and the requirement for the low weight of a whole automobile is met; and the composite air suspension structure is better optimized, the number of parts is reduced, and the requirement for the low weight design of the whole automobile is met.
Description
Technical field
The present invention relates to auto parts and components, specifically leaf springs of car leading arm.
Background technology
Leaf spring leading arm acts primarily as guiding and part carrying effect in composite air suspension, mostly adopts monolithic or two panels fabricated structure.
Its main leaf front-end architecture is substantially the same, namely steel plate after rolling at front end grasswort so that installs that rubber bushing realizes with vehicle frame is hinged, middle part is realized and being fixedly connected of drive axle by bolt, and drive axle part (is stretched out) mainly as the mounting platform of air spring in rear end. Owing to suspension design and arrangement are in close relations, main leaf rear end structure is mainly determined by air spring bearing capacity and arrangement space thereof.
Common straight, the zigzag in current leaf spring leading arm main leaf rear end bends, three kinds of structures of lateral bending. Three of the above structure Shortcomings is as follows:
1. flat type leaf spring leading arm is fixed on vehicle bridge upper end, and for meeting air spring designs height and requirements of installation space, air bag can not be directly installed on leading arm upper surface, it is necessary to fix a special airbag bracket in vehicle bridge lower end. This carrier structure is complicated, and manufacturing cost is higher;
2. " Z " font leaf spring leading arm is fixed on vehicle bridge upper end, though its press-bending structure solves air spring designs height problem very well, but in order to avoid air bag lateral arrangement interference problem (left and right air bag lateral separation is less than left and right leading arm centre-to-centre spacing), air bag can not directly be seated in directly over leading arm, generally requiring and coupled together by left and right leading arm by a crossbeam, air spring is arranged on above crossbeam. Owing to this crossbeam has certain height dimension, leading arm main leaf " Z " font press-bending Partial Height difference is made to increase;
3. though lateral bending template spring leading arm solves air spring horizontal spacing problem very well, air bag can directly be seated in main leaf lateral bending part upper surface, but in order to meet airbag design requirement for height, leading arm can only be fixed on vehicle bridge lower end, the support causing leading arm ear-rolling end and vehicle frame hinged has to strengthen, and its stress condition is also very undesirable, increase manufacturing cost.
Summary of the invention
The deficiency that the present invention is straight in order to leaf spring overcomes, zigzag bends, three kinds of structures of lateral bending are brought, special proposition leaf springs of car leading arm.
The technical scheme is that for this, leaf springs of car leading arm, including flat type leaf spring, is upwards provided with grasswort in flat type leaf spring one end, it is characterized in that: at the other end of flat type leaf spring to having " Z " letter stencil spring, be bent with side on the base of " Z " letter stencil spring to side.
Being improved by such scheme: described side is respectively provided with on the both sides on " Z " letter stencil spring base.
Being improved by such scheme: the base degree in a vertical angle of support arm and straight template spring and " Z " letter stencil spring.
Being improved by such scheme: the base of described side and " Z " letter stencil spring is respectively in the angle of 30-50 ��, and side upper gasbag is installed the center distance from support arm center and is not more than 120mm.
Beneficial effect:
The advantage that leaf springs of car leading arm of the present invention is combined with flat type leaf spring, " Z " font and lateral bending template spring leading arm, solve air spring designs height and lateral arrangement space problem very well, give full play to the mechanical characteristic of spring steel material, make composite air suspension frame structure simplify, meet car load lightweight requirements; Make composite air suspension frame structure more optimize, reduce number of parts, meet car load light-weight design requirement.
It is in order to leaf spring is symmetrical set that side is respectively provided with on the both sides on " Z " letter stencil spring base, convenient installation, and only the change of angle just can realize the symmetry of both sides leaf spring.
The base degree in a vertical angle of support arm and straight template spring and " Z " letter stencil spring, is to enable this leading arm uniform stressed in the vertical direction.
The base of described side and " Z " letter stencil spring is the angle of 30-50 ��, and side upper gasbag is installed the center distance from support arm center and is generally no greater than 120mm, not only easy for installation, also acts as guiding and the effect of location.

Detailed description of the invention
The present invention is as shown in Figure 1,2,3, 4.
Leaf springs of car leading arm, including flat type leaf spring 1, is upwards provided with grasswort 2 in flat type leaf spring 1 one end, at the other end of flat type leaf spring 1 to having " Z " letter stencil spring 3, is bent with side 4 to side on the base of " Z " letter stencil spring 3.
It is respectively provided with to described side 4 on the both sides on " Z " letter stencil spring base, it is adaptable to yellow being symmetrical arranged of Automobile Plate, it is ensured that the symmetry on automobile both sides.
The base degree in a vertical angle of support arm 5 and straight template spring 1 and " Z " letter stencil spring.
The base of side 4 and " Z " letter stencil spring is respectively in the angle of 30-50 ��, and side 4 upper gasbag is installed the center 6 distance from support arm 5 center and is not more than 120mm.
Realized by techniques below means:
1. according to the processing way of conventional flat type leaf spring leading arm main leaf, choose the steel spring plate of dimension undertaken rolling by designing requirement, drill centers, the processes such as grasswort;
2. by special tooling, firing equipment and forcing press, the base of " Z " letter stencil spring is carried out pressure lateral bending to process;
3. design specialized bending die and heating furnace, the power by hydraulic test completes main leaf Z-shaped press-bending process;
