Abstract

The utility model discloses a novel automobile connecting structure with leaf spring suspension and lifting-eye. The novel automobile connecting structure with leaf spring suspension and active lifting-eye comprises an active lifting-eye, a lug support and a leaf spring. The novel automobile connecting structure with leaf spring suspension and active lifting-lug is characterized in that the active lifting-eye is above the lug support; the lower end of the active lifting-eye is arranged on the lug support via a first hinge pin, the upper end of the active lifting-eye is connected with the leaf spring via a second hinge pin; the active lifting-eye swings backward by an angle of 18 DEG C around the center of the pin hole. The novel automobile connecting structure with leaf spring suspension and active lifting-eye has the advantages that firstly, the position of the leaf spring is raised and the center of gravity of the whole automobile is lowered; secondly, when the novel automobile connecting structure with leaf spring suspension and lifting lug is used for matching a low-entry, low-floor bus model, the leaf spring needs not to keep a larger negative arc height, so as to lengthen the service life of the leaf spring; thirdly, when the whole automobile is under braking condition, the horizontal-component directions of the braking force and the active lifting-eye are opposite relatively to the leaf spring eye, so that the stress of the spring eye is reduced.

Description

The movable hanger new Joining Structure of a kind of automotive plate spring suspension
Technical field
The utility model relates to automobile-used engineering field, is specifically related to the novel connection structure of the movable hanger of a kind of automotive plate spring suspension.
Background technology
The movable hanger of Vehicle Leaf-spring Suspension connection structure commonly used is: movable hanger is connected on the shackle bracket by bearing pin, and movable hanger is positioned at the shackle bracket below, and eye of spring plate is connected to movable hanger lower end by bearing pin.This structure has following shortcoming: 1, steel spring is lower with respect to the vehicle frame position, and the car load center of gravity is high; When 2, being used for front suspension, because vehicle bridge can only be arranged in the steel spring below, cause wheel center and vehicle frame distance larger, need that steel spring is made larger negative arc when coupling low floor, low entrance public transport vehicle high, reduction steel spring service life; 3, at the car load damped condition, braking force is identical with respect to the horizontal component of force direction of eye of spring plate with movable hanger, easily causes the eye of spring plate fracture.
Summary of the invention
The utility model purpose is for solving the problem that exists in the above technical scheme, and we have designed a kind of novel, the movable hanging ear structure that eye of spring plate stress is little.
In order to solve these problems of the prior art, the technical scheme that the utility model provides is:
The movable hanger new Joining Structure of a kind of automotive plate spring suspension, comprise movable hanger, shackle bracket and steel spring, it is characterized in that, described movable hanger is positioned at the shackle bracket top, and described movable hanger lower end is assemblied on the shackle bracket by the first bearing pin; Described movable hanger upper end is connected with steel spring by the second bearing pin; Described movable hanger is put certain angle take the pin-and-hole center at the first bearing pin place backward as initial point, the angle ranging from the angle of movable hanger and vertical direction, and size is 15 ° ~ 20 °
Further, above-mentioned angular dimension is preferably 18 °.
Further, also comprise chassis side rail, described shackle bracket is the chassis side rail below fixedly.
Further, described steel spring is combined by some wide not isometric alloy spring sheets, and wherein the longest alloy spring sheet two ends curve grasswort, and described grasswort is connected with the upper end of above-mentioned movable hanger by the second bearing pin.
Than solution of the prior art, the utility model advantage is:
1, raise the steel spring position, and the car load center of gravity reduces;
When 2, being used for the low entrance of coupling, low floor public transport vehicle, it is high that steel spring need not done larger negative arc, is conducive to improve steel spring service life;
3, during the car load damped condition, braking force and movable hanger reduce grasswort stress with respect to the horizontal component of force opposite direction of eye of spring plate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the schematic diagram of the utility model movable hanging ear structure;
Fig. 2 is the schematic diagram of prior art movable hanging ear structure.
Wherein: 1 is movable hanger, and 2 is shackle bracket; 3 is steel spring; 4 is the first bearing pin; 5 is the second bearing pin; 6 is chassis side rail.
The specific embodiment
Below in conjunction with specific embodiment such scheme is described further.Should be understood that these embodiment are not limited to limit the scope of the invention for explanation the present invention.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
Embodiment as shown in Figure 1, the movable hanger new Joining Structure of a kind of automotive plate spring suspension, comprise movable hanger 1, shackle bracket 2 and steel spring 3, described movable hanger 1 is positioned at shackle bracket 2 tops, and described movable hanger 1 lower end is assemblied on the shackle bracket 2 by the first bearing pin 4; Described movable hanger 1 upper end is connected with steel spring 3 by the second bearing pin 5; Described movable hanger 1 is put angle about 18 ° backward take the pin-and-hole center at the first bearing pin 4 places as initial point.
Also comprise chassis side rail 6, described shackle bracket 2 is chassis side rail 6 belows fixedly.
Described steel spring 3 is combined by some wide not isometric alloy spring sheets, and wherein the longest alloy spring sheet two ends curve grasswort, and described grasswort is connected with the upper end of above-mentioned movable hanger 1 by the second bearing pin 5.
Above-mentioned example only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalent transformations that Spirit Essence is done according to the present invention or modification all should be encompassed within protection scope of the present invention.
The utility model discloses the movable hanger new Joining Structure of a kind of automotive plate spring suspension, comprise movable hanger, shackle bracket and steel spring, it is characterized in that, described movable hanger is positioned at the shackle bracket top, and described movable hanger lower end is assemblied on the shackle bracket by the first bearing pin; Described movable hanger upper end is connected with steel spring by the second bearing pin; Described movable hanger is put angle about 18 ° backward take the pin-and-hole center at the first bearing pin place as initial point.Structure described in the utility model has the following advantages, and 1. raise the steel spring position, and the car load center of gravity reduces; 2. when being used for the low entrance of coupling, low floor public transport vehicle, it is high that steel spring need not done larger negative arc, is conducive to improve steel spring service life; 3. during the car load damped condition, braking force and movable hanger reduce grasswort stress with respect to the horizontal component of force opposite direction of eye of spring plate.
