Abstract
The invention provides a shock absorbing buffering device for a small electric sweeper. The device comprises a bracket, two support seats arranged on the bracket, and U-shaped hanging brackets connected with the support seats. The bracket is connected with a shearing spring made of rubber and a rigidity variable spring made of rubber. The device provided by the invention has the following technical effects that 1, as the elastic elements made of rubber, namely the shearing spring and the rigidity variable spring are adopted to replace the existing coiled spring, the shock absorbing and buffering effects of the device are more prominent, and the working performance is more stable and reliable; as the vulcanized rubber is used as the elastic elements which are arranged in a V shape, the upper taper rubber elastic element can realize rigidity changing and buffering, and the combination of the elastic elements can play roles of longitudinal, horizontal and vertical buffering and shock absorbing on vehicles, thereby improving the stability of vehicle travelling and comfort of driving; 2, the design layout is reasonable, the structure is compact, and the device is suitable for the compact structure of the small electric sweeper, and the layout of other working facilities of the sweeper is not affected.
Description
Technical field
The present invention relates to a kind of small-sized electric cleaning car, specifically, relate to a kind of shock absorption buffering mechanism of small-sized electric cleaning car.
Background technology
When electric cleaning car goes and works in the place of injustice, bear the impact of different road, in order to guarantee the stability and the reliability of vehicle control syetem and mechanical system work; Pickup sweeper has certain requirement to the damping, buffering of whole car, because small-sized electric cleaning car has many specific facilities, the space is narrow; If adopt conventional suspension gear to carry out damping and buffering; Can make system too complicated, and be difficult to settle, cost also increases thereupon.
Therefore, develop a kind of shock absorption buffering mechanism of the compact form of small-sized electric cleaning car that is applicable to and be necessity in fact, can not only play the effect of damping, buffering, the normal operation of assurance onboard system, also reduced cost.
Summary of the invention
The objective of the invention is to overcome the weak point of prior art, a kind of shock absorption buffering mechanism of small-sized electric cleaning car is provided.
The shock absorption buffering mechanism of small-sized electric cleaning car of the present invention comprises support, is located at two bearings on the support, the U type suspension bracket that links to each other with two bearings, is connected with the shear spring of rubber material and the variable rate spring of rubber material on the described support.
Described rubber shear spring is a V-type, and described rubber variable rate spring is taper.
The shock absorption buffering mechanism of small-sized electric cleaning car of the present invention has following technique effect:
1) through using elastic element---the shear spring and the variable rate spring of rubber material, substitutes coil spring in the past, make the serviceability of this shock absorption buffering mechanism more reliable and more stable; Use polysulphide rubbers as the V-shaped layout of elastic element; The cone rubber elastic element on top can be realized variable rigidity shock absorption; The effect that can play vertical, horizontal and vertical bumper and absorbing shock to vehicle is used in both combinations, thereby improves the stability of vehicle ' and the traveling comfort of driving;
2) layout rationally, compact conformation, be applicable to the narrow structure of small-sized electric cleaning car, do not influence the layout of other work facility of pickup sweeper;
3) working service is more convenient, has reduced productive costs.
Description of drawings
Fig. 1 is the front view of the shock absorption buffering mechanism of small-sized electric cleaning car of the present invention.
Fig. 2 is the left view of Fig. 1.
Wherein, 1 is vehicle frame, and 2 is support, and 3 is bearing, and 4 is wheel, and 5 is suspension bracket, and 6 is shear spring, and 7 is variable rate spring.
The specific embodiment
Like Fig. 1, shown in 2; The shock absorption buffering mechanism of small-sized electric cleaning car of the present invention is suspended between the vehicle frame 1 and wheel 4 of pickup sweeper, is connected with support 2 on the vehicle frame 1; Support 2 is provided with two bearings 3; Be connected with U type suspension bracket 5 between two bearings 3 and the wheel 4, said support 2 is provided with shear spring 6 and variable rate spring 7, and wheel 4 is connected with said shear spring 6 through said suspension bracket 5.
Wherein, said shear spring 6 and said variable rate spring 7 are the elastic element of rubber material.Rubber shear spring 6 is a V-type, and rubber variable rate spring 7 is taper.
The workflow of the shock absorption buffering mechanism of small-sized electric cleaning car of the present invention is following: when electric cleaning car is worked on the road surface of jolting; Ground-surface impact and vibrations are passed on shear spring 6 and the variable rate spring 7 through suspension bracket 5 and bearing 3 by wheel 4; The shear spring 6 and the variable rate spring 7 of rubber material can play the effect of damping, buffering; Can play spacing effect again, therefore realize goal of the invention of the present invention.
