Abstract
The utility model relates to a bicycle frame, in particular to a shock absorption bicycle frame with a reinforced auxiliary spar. The shock absorption bicycle frame with the reinforced auxiliary spar comprises a front fork sleeve, a saddle drivepipe, a center shaft drivepipe and a back shaft fork frame. The shock absorption bicycle frame with the reinforced auxiliary spar is characterized in that the saddle drivepipe and the center shaft drivepipe are connected through an L-shaped beam. The front fork sleeve and the bent portion of the L-shaped beam are connected through an upper beam. The center shaft drivepipe and the middle portion of the upper beam are connected through the reinforced auxiliary spar. The back shaft fork frame is hinged with the lower end of the L-shaped beam through a rotating shaft. The upper end of the back shaft fork frame and the bent portion of the L-shaped are connected through a vibration proof spring. Due to the above structure, the compressive strength is increased, so that the structure is more stable. In addition, due to the fact that the back shaft fork frame is hinged with the lower end of the L-shaped beam through the rotating shaft, and the upper end of the back shaft fork frame and the bent portion of the L-shaped are connected through the vibration proof spring, vibration can be absorbed as much as possible through shape changes of the bicycle frame, and therefore the safety and comfort of bicycles are improved.
Description
Technical field
The utility model relates to a kind of cycle frame, relates in particular to a kind of shock-absorptive frame of bicycle with strengthening floor stringer.
Background technology
The vehicle frame of bicycle generally comprises for the front fork sleeve that front fork is installed in the prior art, be used for installing the saddle sleeve pipe of saddle, be used for installing the axis sleeve pipe of axis, connect by putting the beams in place between front fork sleeve and the saddle sleeve pipe, connect by cant beam between axis sleeve pipe and the front fork sleeve, and be connected by vertical beam between saddle sleeve pipe and the axis sleeve pipe, also establish in addition the rear axle crotch for the installation trailing wheel, rear axle crotch one end is used for rear axle is installed, and the other end is captiveed joint with the axis sleeve pipe.
But in the prior art since the rear axle crotch captive joint with the axis sleeve pipe so that bicycle rack on the whole can't deformation and the absorption driving process in jolting, when pavement conditions is bad, easily cause the too early fatigue of user, affect safety traffic and comfort level.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of stabilized structure to have the cycle frame with the damping of strengthening floor stringer of fine damping effect.
The utility model is to be achieved by the following technical programs:
A kind of shock-absorptive frame of bicycle with strengthening floor stringer, comprise front fork sleeve, saddle sleeve pipe, axis sleeve pipe and rear axle crotch, it is characterized in that, the saddle sleeve pipe is connected by L shaped beam with the axis sleeve pipe, be connected by putting the beams in place between the bending part of front fork sleeve and L shaped beam, the axis sleeve pipe is connected by strengthening floor stringer between the middle part with putting the beams in place, and described rear axle crotch is hinged by rotating shaft and L shaped beam lower end, is connected by shock-proof spring with the bending part of L shaped beam on the described rear axle crotch.
The beneficial effects of the utility model are:
Because the saddle sleeve pipe is connected by L shaped beam with the axis sleeve pipe, be connected by putting the beams in place between the bending part of front fork sleeve and L shaped beam, the axis sleeve pipe is connected by the reinforcement floor stringer between the middle part with putting the beams in place, can increase its compressive strength makes structure more firm, described rear axle crotch is hinged by rotating shaft and L shaped beam lower end in addition, described rear axle crotch upper end is connected by shock-proof spring with the bending part of L shaped beam, and the deformation by bicycle rack comes absorbing vibration as much as possible, improves safety and the traveling comfort of bicycle.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present utility model.
Among the figure: 1. saddle sleeve pipe, the 2.L ellbeam, 3. front fork sleeve is 4. put the beams in place, 5. axis sleeve pipe, 6. rear axle crotch, 7. shock-proof spring is 8. strengthened floor stringer.
The specific embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with accompanying drawing and most preferred embodiment.
As shown in Figure 1, the utility model comprises front fork sleeve 3, saddle sleeve pipe 1, axis sleeve pipe 5 and rear axle crotch 6, it is characterized in that, the saddle sleeve pipe is connected by L shaped beam 2 with the axis sleeve pipe, 4 be connected by putting the beams in place between the bending part of front fork sleeve and L shaped beam, the axis sleeve pipe is connected by strengthening floor stringer 8 between the middle part with putting the beams in place, and described rear axle crotch is hinged by rotating shaft and L shaped beam lower end, is connected by shock-proof spring 7 with the bending part of L shaped beam on the described rear axle crotch.
Because the saddle sleeve pipe is connected by L shaped beam with the axis sleeve pipe, be connected by putting the beams in place between the bending part of front fork sleeve and L shaped beam, the axis sleeve pipe is connected by the reinforcement floor stringer between the middle part with putting the beams in place, can increase its compressive strength makes structure more firm, described rear axle crotch is hinged by rotating shaft and L shaped beam lower end in addition, described rear axle crotch upper end is connected by shock-proof spring with the bending part of L shaped beam, and the deformation by bicycle rack comes absorbing vibration as much as possible, improves safety and the traveling comfort of bicycle.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
