Abstract
The utility model discloses a damper comprising a front forked pipe, a link plate, a lower spring seat, a guide sleeve, and a guide shaft, wherein the front forked pipe consists of an upper forked pipe and a lower forked pipe; the link plate is connected at the upper end of the front forked pipe; the lower spring seat is fixedly connected on the lower forked pipe; the guide sleeve is fixedly connected on the lower forked pipe under the lower spring seat and has the axle line being parallel to that of the front forked pipe; and the guide shaft with the upper end being fixedly connected on the link plate is connected inside the guide sleeve in a sliding way. The damper has the advantages of small wearing and long service life.
Description
Technical field
The utility model relates to a kind of bumper, is specifically related to a kind of bumper that is used for agricultural tricycle.
Background technology
The existing bumper that is used for agricultural tricycle, comprise front fork tube of forming by upper branch pipe and following breeches pipe and the yoke plate that is connected the front fork tube upper end, be connected with on the upper branch pipe and be connected with down spring abutment under the spring abutment on the breeches pipe, be set with coil spring between the upper and lower spring abutment, the lower end of following breeches pipe is connected with and car front-wheel bonded assembly jaw.The said structure bumper tilts to be connected between car front-wheel and the steering hardware, the gravity of vehicle is vertically downward, gravity vertically downward can be decomposed into along the axial axial force of front fork tube with perpendicular to the front fork tube axis and point to the normal force of front fork tube inboard, because the existence of normal force, bring following two kinds of defectives: the one, the coil spring unbalance stress causes the mutual wearing and tearing between the surface of coil spring and front fork tube, and the 2nd, lateral wearing is serious within it with following breeches pipe for upper branch pipe.Caused whole defective shock absorber fast thus, service life is short.
The utility model content
The technical problems to be solved in the utility model is at above-mentioned deficiency, and a kind of bumper that can effectively reduce wearing and tearing, long service life is provided.
In order to solve the problems of the technologies described above, the utility model provides a kind of bumper of following structure, comprise the following spring abutment on the front fork tube of forming by upper branch pipe and following breeches pipe, the yoke plate that is connected the front fork tube upper end and the affixed breeches pipe down, its constructional feature: below following spring abutment, be connected with the guide pin bushing of the parallel axes of its axis and front fork tube on the breeches pipe down, slidely connect the guide shaft that is fixed on it on yoke plate in the guide pin bushing.
The bumper of said structure, owing to be connected with the guide pin bushing of the parallel axes of its axis and front fork tube on the following breeches pipe, slidely connect its upper end in the guide pin bushing and be fixed in guide shaft on the yoke plate, make upper branch pipe and guide shaft form a rectangular frame structure by yoke plate and guide pin bushing, improved bending strength, greatly reduce the normal force that acts on the front fork tube, mutual wearing and tearing and upper branch pipe and the wearing and tearing of side within it of following breeches pipe between the corresponding surface that has reduced coil spring and front fork tube, therefore, the utlity model has the advantage little, long service life of wearing and tearing.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Bumper as shown in drawings, comprise the front fork tube of forming by upper branch pipe 1 and following breeches pipe 2, the yoke plate 3 that is connected the front fork tube upper end, be connected with spring abutment 7 on the upper branch pipe 1, be connected with down spring abutment 4 on the following breeches pipe 2, be set with coil spring 8 between last spring abutment 7 and the following spring abutment, the lower end of following breeches pipe 2 is connected with and car front-wheel bonded assembly jaw 9.Below following spring abutment 4, be connected with guide pin bushing 5 on the breeches pipe 2 down, the axis of guide pin bushing 5 and the parallel axes of front fork tube are equipped with guide shaft 6 in the guide pin bushing 5, and guide shaft 6 can endwisely slip along guide pin bushing 5, and the upper end of guide shaft 6 is fixed on the yoke plate 3.
Claims (1)
