Abstract

The utility model discloses a bicycle frame. A middle tube, a first lower fork, a second lower fork, a lower tube and a five-way valve on the frame are made from a carbon fiber material and are integrally or separately molded; a reinforcing rib made from the carbon fiber material is integrally formed between the middle tube and at least one side of each of the first lower fork and the second lower fork; reinforcing ribs made from the carbon fiber material are respectively formed between two sides of the middle tube and the first and the second lower forks; and the two reinforcing ribs are arranged in a symmetric or asymmetric way; and the bicycle frame disclosed by the utility model has the advantages that more reasonable strength and rigidity are obtained and energy loss caused by insufficient rigidity of the frame is reduced.

Description

Cycle frame

Technical field

The utility model relates to a kind of cycle frame, and particularly a kind of strength rigid that improves vehicle frame reduces the vehicle frame of the degradation of energy that causes because of vehicle frame rigidity deficiency.

Background technology

This cycle frame common vehicle frame that compares, not only intensity is bigger, and structure is more reasonable; Therefore increasingly high to the requirement of bicycle frame pipe material, the pipe fitting of being processed by the fine material of carbon is the bicycle racing important materials, at present; Though pipe fitting has adopted this material; But in order to guarantee that vehicle frame has enough intensity and rigidity, the intensity of middle pipe is through increasing its end section, and is enough solid with middle pipe, lower fork, following pipe and five-way bonded assembly position pipe fitting in addition; Could guarantee the intensity of whole vehicle frame, but such frame strength and rigidity are desirable not to the utmost.

Summary of the invention

In order to remedy above deficiency, the utility model provides a kind of cycle frame, and intensity and rigidity are more reasonable, reduces the degradation of energy that causes because of vehicle frame rigidity deficiency.

The technical scheme of the utility model is such realization: a kind of cycle frame; Middle pipe on this vehicle frame, first lower fork, second lower fork, following pipe, five-way are all processed by the fine material of carbon; Pipe, first lower fork, second lower fork, following pipe and five-way are formed in one in being somebody's turn to do, the integrally formed reinforced rib of being processed by carbon fibre material between at least one side in this in pipe and first lower fork and second lower fork.

As the further improvement of the utility model, pipe, first lower fork, second lower fork, following pipe and five-way are body formed for dividing in this.

As the further improvement of the utility model, pipe both sides form the reinforced rib of being processed by the fine material of carbon respectively and between first lower fork and second lower fork in this.

As the further improvement of the utility model, this two reinforced rib be the symmetry and asymmetric the setting in a kind of.

The useful technique effect of the utility model is: said vehicle frame is processed by the fine material of carbon; This body frame structure for automotive is reasonable in design; Reduced five-way to the distance of colluding the pawl center; Possess good gearshift performance and good handling, improve the intensity and the rigidity that promotes vehicle frame of vehicle frame, reduce the degradation of energy that causes because of vehicle frame rigidity deficiency.

Contrast above accompanying drawing, make following supplemental instruction:

1---middle pipe 4---five-way

21---first lower forks 22---, first lower fork

3---managing 5 down---reinforced rib

The specific embodiment

In conjunction with Fig. 1, Fig. 2 and Fig. 3, below describe in detail:

A kind of cycle frame; Middle pipe 1 on this vehicle frame, first lower fork 21, second lower fork 22, manage 3 down, five-way 4 all processed by the fine material of carbon; Should in pipe 1, first lower fork 21, second lower fork 22, down manage 3 and five-way 4 for one or divide body formed, the integrally formed reinforced rib of processing by carbon fibre material 5 between at least one side in this in pipe 1 and first lower fork and second lower fork.

In order further to improve intensity; Should in the pipe both sides form the reinforced rib of processing by the fine material of carbon respectively and between first lower fork and second lower fork; This two reinforced rib be the symmetry and asymmetric the setting in a kind of; The reinforced rib that has between pipe and the lower fork in being somebody's turn to do, its effect are to improve the intensity of vehicle frame and the rigidity of lifting vehicle frame, reduce the degradation of energy that causes because of vehicle frame rigidity deficiency.
