Abstract
A spring eye local reinforcement structured multiple-plate spring is formed by a certain number of plate springs, and is characterized in that the thickness of the first plate spring is equal to that of other springs, the thickness of the first plate spring is thickened when transiting to the spring eye. The utility model has the advantages that: 1. the structure breaks through the design concept of the uniform section of the multiple-plate spring, and the spring eye is thickened; 2. the structure basically improves the whole reliability of the multiple-plate spring; and 3. the structure improves the utilization factor of the plate spring material and reduces the cost.
Description
Technical field
During this practical new technology belongs to, the technical field of heavy goods vehicles suspension system, the local reinforced structure Multi-Leaf Springs of particularly a kind of grasswort.
Background technique
Leaf spring is a vitals in the vehicle suspension system, and the power and the effects such as moment, mitigation body oscillating of play and bear car body weight, transmitting all directions have crucial influence to the run smoothness and the control stability of car load.
In at present domestic, the heavy truck field, the suspension system operating conditions is abominable.Traditional multi-disc uniform section leaf spring is because manufacturing process is simple, and cost of production is low, and maintenance is convenient, so be used widely on medium and heavy truck.This spring is formed by some uniform section reed superpositions, grasswort thickness and blocks of thick equating.Some operating mode for guaranteeing the intensity of grasswort, often adopts the increase slices thick, reaches the grasswort method of thickening synchronously, to strengthen grasswort.This method often makes not uniform thickness of main leaf and other sheet, causes the unreasonable and complex process of each sheet stress distribution.
Summary of the invention:
The purpose of this utility model is to provide a kind of grasswort local reinforced structure Multi-Leaf Springs.
The technical solution of the utility model is achieved in that
The local reinforced structure Multi-Leaf Springs of grasswort, it is made up of the leaf spring of some, it is characterized by: first thick and other each sheet equal thickness of leaf of spring, the sheet of first leaf spring is thick, and sheet is thick when carrying out the transition to the grasswort position thickens.
Advantage of the present utility model is:
1, this structure breaks through the uniform section design concept of traditional Multi-Leaf Springs, and grasswort is partly thickeied.
2, this structure has fundamentally improved the global reliability of Multi-Leaf Springs.
3, this structure has improved the utilization ratio of leaf spring material, has reduced cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model force analysis schematic representation.
Fig. 3 is the utility model assembly structure schematic representation.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
The local reinforced structure Multi-Leaf Springs of grasswort, it is made up of the leaf spring of some, it is characterized by: 1 thick and other each sheet equal thickness of first leaf spring, the sheet of first leaf spring 1 is thick, and sheet is thick when carrying out the transition to grasswort position 2 thickens.
As Fig. 1, Fig. 2 and shown in Figure 3,1 of first leaf spring is thick to be h, now with 2 thickenings of grasswort part, thickness is H, h＜H, when spring eye transmitted braking force or driving force, bending that the grasswort place is subjected to and tension and compression made a concerted effort to be Px, because H is greater than h, so grasswort place stress is reduced significantly.
Claims (1)
1. the local reinforced structure Multi-Leaf Springs of grasswort, it is made up of the leaf spring of some, it is characterized by: first leaf spring (1) and other each sheet equal thickness, thickness thickened when the thickness of first leaf spring (1) carried out the transition to grasswort position (2).
