Description
Technical field
The invention belongs to road sweeper technical field, be specifically related to a kind of anti-shock structure of front wheel.
Background technology
In order to improve navigating mate operation comfort, reducing and excessive damage being caused to car body parts because shaking in driving process, effectively extending vehicle life span; Existingly be mainly concerned with two schemes: scheme one, front-wheel install the damping of four-point supporting formula additional, this damping modes is four support spring dampings by being fixed on front-wheel both sides, shortcoming is after wherein a spring gets rusty distortion, fatigue, 4 discontinuity can be caused, thus front-wheel is balanced, serious meeting causes front-wheel sideslip to cause disconnected front wheel spindle; Scheme two, adopt hinged mode at front-wheel adapter plate and car body junction, use spring, damping is realized by the angle changing front-wheel adapter plate and car body, the program can constantly change due to the angle of front-wheel adapter plate and car body, the operating effort of the steering structure above it will inevitably be caused also to be in a kind of unsure state, to affect steering operation performance when vehicle travels and safety.
Summary of the invention
The object of the invention is to propose a kind of anti-shock structure of front wheel, overcome the above-mentioned deficiency of prior art, its structure design is simple, science, stability is high, efficiently avoid the problems such as front wheel spindle distortion, fracture, improves its life-span, there is good safety, be conducive to the popularization of product.
In order to reach above-mentioned design goal, the technical solution used in the present invention is as follows:
A kind of anti-shock structure of front wheel, comprise front wheel fixing seat, damping spring, front-wheel, front wheel spindle, shock-absorbing rocker arm, described front wheel fixing seat is inverted U-shaped, the opening part of front wheel fixing seat is coupling front-wheel, the front wheel spindle two ends of described front-wheel are separately fixed on two relative shock-absorbing rocker arms, one end of described two shock-absorbing rocker arm homonymies is coupling at the open end of front wheel fixing seat respectively, and the hinged damping spring lower end of the described shock-absorbing rocker arm other end, damping spring upper end thereof is on front wheel fixing seat.
Preferably, the open end of described front wheel fixing seat is respectively equipped with relative arc-shaped slot, and the front wheel spindle two ends of front-wheel are each passed through slotted eye rear axle and are connected on shock-absorbing rocker arm.
Preferably, described shock-absorbing rocker arm is coupling on front wheel fixing seat by rocking arm hinge.
Preferably, described damping spring upper end is fixed together by anchor shaft on damping spring and front wheel fixing seat, and damping spring lower end is hinged by one end of anchor shaft under damping spring and shock-absorbing rocker arm.
The beneficial effect of anti-shock structure of front wheel of the present invention is: structure design is simple, science, and stability is high, efficiently avoid the problems such as front wheel spindle distortion, fracture, improves its life-span, have good safety, be conducive to the popularization of product.

Detailed description of the invention
Below optimum implementation of the present invention is described in further detail.
As Figure 1-4, described anti-shock structure of front wheel, comprise front wheel fixing seat 1, damping spring 3, front-wheel 4, front wheel spindle 5, shock-absorbing rocker arm 7, described front wheel fixing seat 1 is inverted U-shaped, the opening part of front wheel fixing seat 1 is coupling front-wheel 4, front wheel spindle 5 two ends of described front-wheel 4 are separately fixed on two relative shock-absorbing rocker arms 7, one end of described two shock-absorbing rocker arm 7 homonymies is coupling at the open end of front wheel fixing seat 1 respectively, described shock-absorbing rocker arm 7 other end hinged damping spring 3 lower end, damping spring 3 upper end thereof is on front wheel fixing seat 1, during use, front wheel spindle 5 can shock-absorbing rocker arm 7 one end be axis rotation, the damping spring 3 of compression shock absorption rocking arm 7 other end, thus realize damping effect, its damping effect is stablized, and dynamics non-immediate to act on damping spring 3 and (first acts on shock-absorbing rocker arm 7 to be coupling with front wheel fixing seat 1 and to locate during damping, then shock-absorbing rocker arm 7 rotary action is passed through in damping spring 3), drastically increase the life-span of damping spring 3, safety is higher.
The open end of described front wheel fixing seat 1 is respectively equipped with relative arc-shaped slot 9, front wheel spindle 5 two ends of front-wheel 4 are each passed through slotted eye 9 rear axle and are connected on shock-absorbing rocker arm 7, when shock-absorbing rocker arm 7 rotates, the front wheel spindle 5 of front-wheel 4 moves up and down in slotted eye 9, thus realize damping, and slotted eye 9 limits the ultimate range that front wheel spindle 5 moves up and down, prevent damping spring 3 supercompression of shock-absorbing rocker arm 7 other end, affect its life-span.
Described shock-absorbing rocker arm 7 is coupling on front wheel fixing seat 1 by rocking arm hinge 8.
Described damping spring 3 upper end is fixed together by anchor shaft on damping spring 2 and front wheel fixing seat 1, and damping spring 3 lower end is hinged with one end of shock-absorbing rocker arm 7 by anchor shaft under damping spring 6.
As shown in Figure 4, described front wheel damping device is applied to three-wheel driving type road sweeper, when garage goes to the place that there is fluctuating on road surface, front-wheel 4 is impacted, and acts on shock-absorbing rocker arm 7 by front wheel spindle 5, and the rocking arm hinge 8 of shock-absorbing rocker arm 7 on front wheel fixing seat 1 rotates, damping spring 3 is compressed, damping spring 3 is provided with damping element, and damping element consumes rapidly the energy produced by impacting, thus plays the effect of damping.This structure should use symmetrical rocker structure that front-wheel 4 is connected with front wheel fixing seat 1, and the balance of front-wheel is ensured by hinge, which avoid the front-wheel unbalance that the quality problems of producing appearance due to spring failure or spring cause.Because this structure is all on front wheel fixing seat 1, does not affect the connection of front wheel fixing seat 1 and car body, therefore do not affect the operating characteristic of Vehicular turn.
It is worth mentioning that, the arc-shaped slot 9 at the center on front wheel fixing seat 1 plays the effect of restriction front wheel spindle 5 hunting range, there is extreme situation, as spring breakage, front-wheel also can rely on the supporting role of the arc-shaped slot 9 at the center on front wheel fixing seat 1, keep the walking performance of vehicle not by serious impact, improve the safety of driving.
Above content is the further description done the present invention in conjunction with concrete preferred implementation, and being convenient to these those skilled in the art can understand and apply the invention, and can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, some simple deduction or replace can also be made without departing from the inventive concept of the premise, and need not through performing creative labour.Therefore, those skilled in the art are according to announcement of the present invention, and the simple modifications made the present invention all should within protection scope of the present invention.
