Abstract

The utility model discloses a rear shock absorber spring spacer bush for a motorcycle. A round spring abutting-against platform is integrally arranged at the lower end of an outer wall of a body, an inner wall and the outer wall of the body are cylindrical surfaces, 3-6 first axial protruded strips are evenly distributed along the circumference of the outer wall of the body, the upper ends of the first axial protruded strips are close to the top surface of the body, 4-8 second axial protruded strips are evenly distributed along the circumference of the inner wall of the body, and the upper ends of the second axial protruded strips are flush with the top surface of the body. The first axial protruded strips, the second axial protruded strips and the body are of an integrated structure and are formed by injection molding. The axial protruded strips are evenly distributed along the circumferences of both the inner wall and the outer wall of the body on the basis of a traditional structure, so that not only is injection molding facilitated, but also processing difficulty is reduced, the shortcomings of bubbles and shrinkage cavities and the like are overcome, product quality and service lives are guaranteed, the contact area between the rear shock absorber spring spacer bush and a spring and a shock absorber working cylinder can be reduced well, resistance is reduced, and the spring and the shock absorber working cylinder can be guided well.

Description

Rear shock absorber of motorcycle spring spacer

Technical field

The utility model belongs to motorcycle vibration absorber field, specifically, relates in particular to a kind of rear shock absorber of motorcycle spring spacer.

Background technique

Spring spacer is one of vitals on rear shock absorber of motorcycle, and this spring spacer is for keeping apart spring and clutch release slave cylinder.Described spring spacer is plastic sheath, and by molding and forming, the inside and outside wall of this spring spacer is complete smooth cylndrical surface, and the underpart of spring spacer outside is integrally formed with a circular spring abutment platform.During use, spring housing is contained in spring spacer outside, the spring abutment platform butt of its lower end and spring spacer, and vibration damper clutch release slave cylinder is located in the endoporus of spring spacer.

The defect of existing spring spacer is: because spring spacer is plastic sheath, and by molding and forming, the inside and outside wall of this spring spacer is complete smooth cylndrical surface, while so not only causing injection moulding, easily produce the mass defects such as bubble, shrinkage cavity, thereby affect quality and the working life of product, and spring and clutch release slave cylinder all with spring every whole sidewall contact, so just cause resistance and noise larger, and steering capability is poor, be badly in need of solving above-mentioned technical barrier for this reason.

Model utility content

Technical problem to be solved in the utility model is to provide a kind of rear shock absorber of motorcycle spring spacer, wants to overcome conventional construction and is the defect that complete circle cylinder causes because of spacer inside and outside wall.

The technical solution of the utility model is as follows: a kind of rear shock absorber of motorcycle spring spacer, comprise body (1), the making material of this body is plastics, and in the underpart of body (1) outer wall, be integrally formed with a circular spring abutment platform (1a), and the inside and outside wall of body (1) is cylndrical surface, it is characterized in that: on the outer wall of described body (1), edge is circumferentially evenly equipped with 3-6 the first axial raised line (1b), the upper end of this first axial raised line is near the end face of body (1), and the lower end of the first axial raised line (1b) is connected with described spring abutment platform (1a) end face, on the inwall of described body (1), along being circumferentially evenly equipped with 4-8 the second axial raised line (1c), the upper end of this second axial raised line is concordant with the end face of body (1), and the lower end of two axial raised lines (1c) is near the bottom surface of body (1).The described first axial raised line (1b) and the second axial raised line (1c) are structure as a whole with body (1), and by molding and forming.

Adopt above technological scheme, the utility model on the basis of conventional construction at the inside and outside wall of body all along being circumferentially evenly equipped with axial raised line, so not only be convenient to molding and forming, thereby reduction difficulty of processing, and avoid occurring the defects such as bubble, shrinkage cavity, and then assurance quality of product and working life, and the area of contact of reduction and spring and decoupling rod well, thereby reduce resistance, and can fine they be led, and the utility model has just solved the defect of conventional construction by little change, have good practicability, is suitable for extensively promoting the use.

In this case, the number of the described first axial raised line (1b) is 4, and the number of the described second axial raised line (1c) is 6.Certainly, in actual manufacture process, we can select according to actual conditions the respective number of first and second axial raised line, and its number is not take the quantity described in the present embodiment as restriction.

As optimal design, the width of the described first axial raised line (1b) is 4-5mm, and the both sides of this first axial raised line are connected with described body (1) outer wall by inclined-plane.

As preferably, the width of the described second axial raised line (1c) is 4-4.2mm, and the both sides of this second axial raised line (1c) are connected with described body (1) inwall by inclined-plane.

For the ease of drawing materials, and reduce manufacture cost, spy elects the making material of described body (1) as PVC.

Beneficial effect: the utility model on the basis of conventional construction at the inside and outside wall of body all along being circumferentially evenly equipped with axial raised line, so not only be convenient to molding and forming, thereby reduction difficulty of processing, and avoid occurring the defects such as bubble, shrinkage cavity, and then assurance quality of product and working life, and the area of contact of reduction and spring and decoupling rod well, thereby reduce resistance, and can fine they be led, and the utility model has just solved the defect of conventional construction by little change, there is good practicability, be suitable for extensively promoting the use.
