Abstract
The utility model relates to an engine fitting, in particular to a tensioning wheel structure for adjusting the tightness degree of a chain, comprising a tensioning wheel and a fixed supporting arm, wherein the tensioning wheel is arranged on a transmission chain of the dune buggy, and one end of the fixed support arm is fixedly connected with a shaft of the tensioning wheel; the other end of the fixed supporting arm is connected with a rear rocking frame of the dune buggy in a rotating manner by a connecting rod; and a torsion spring is sheathed outside the connecting rod, one end of the torsion spring is fixed on the rear rocking frame of the dune buggy, and the other end of the torsion spring is fixed on the fixed supporting arm. By adopting the structure, the torsion spring is used for providing force for tensioning the transmission chain to the tensioning wheel connected with the fixed supporting arm, so that the transmission chain of the dune buggy is always in a tensioning state, and further the purpose of keeping the tightness of the transmission chain can be achieved.
Description
Technical field
The utility model relates to a kind of engine fittings, particularly a kind of tension wheel structure of regulating the chain degree of tightness.
Background technique
Beach buggy can be used roomy tire because of it on soft sand ground increase and the bigger frictional force of area of contact generation on the ground, and cooperating unique tread is the unsuitable slipping of tire, and travels on sand ground easily.Quality is good, the beach buggy of function admirable can not only go sandy beach, riverbed, forest-road, streams even worse desert can both overcome easily.Beach buggy just needs very powerful motivation like this, and the distance between motor and the sprocket wheel is distant again, in the process of going, occurs the loosening phenomenon of chain easily, so need provide a kind of tension structure to keep chain not loosening.
Summary of the invention
The utility model technical issues that need to address provide a kind of tension structure that keeps beach buggy chain degree of tightness.
For solving above-mentioned technical problem, the beach buggy tension structure of the utility model comprises Idle wheel and fixing branch brace, and said Idle wheel is arranged on the drive chain of beach buggy, and an end of said fixing branch brace is fixedly connected with the axle of Idle wheel; The other end of said fixing branch brace through connecting rod and beach buggy after reel cage be rotationally connected; Said connecting rod is with torsion spring outward, and an end of said torsion spring is fixed on behind the beach buggy on the reel cage, and the other end is fixed in the fixing branch brace.
After adopting said structure, rely on torsion spring to give the power that drive chain is tightened of Idle wheel that links to each other with the fixing branch brace, make the drive chain of beach buggy be in the state of tightening constantly, reach the tight purpose of maintenance drive chain.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the stravismus structural representation of the utility model beach buggy tension structure.
Among the figure: 1 is drive chain, and 2 is Idle wheel, and 3 is the fixing branch brace, and 4 is connecting rod, and 5 is the back reel cage, and 6 is torsion spring
Embodiment
Beach buggy tension structure as shown in Figure 1; Comprise Idle wheel 2 and fixing branch brace 3; Said Idle wheel 2 is arranged on the drive chain 1 of beach buggy, and an end of said fixing branch brace 3 is fixedly connected with the axle of Idle wheel 2, and beach buggy is when advancing like this; Idle wheel 2 can rotate under the drive of drive chain 1, can not influence the work of drive chain.The other end of said fixing branch brace 3 is rotationally connected through reel cage 5 behind connecting rod 4 and the beach buggy; Said connecting rod is with torsion spring 6 outward, and an end of said torsion spring 6 is fixed on behind the beach buggy on the reel cage 5, and the other end is fixed in the fixing branch brace 3.
Said Idle wheel 2 is arranged on drive chain 1 inboard.
Said Idle wheel 2 is arranged on drive chain 1 outside.
When Idle wheel 2 is arranged on drive chain 1 outside, need to give the fixing branch brace 3 one pressure to drive chain 1 inboard through torsion spring 6, make drive chain 1 be in pressured state, drive chain 1 will be in tensioned state always like this.
When Idle wheel 2 is arranged on drive chain 1 inboard, need to give 3 one thrusts of fixing branch brace to drive chain 1 outside through torsion spring 6, make drive chain 1 to extrapolation, the same like this drive chain 1 that can make is in tensioned state.
Claims (3)
1. a beach buggy tension structure comprises Idle wheel and fixing branch brace, and said Idle wheel is arranged on the drive chain of beach buggy, it is characterized in that: an end of said fixing branch brace is fixedly connected with the axle of Idle wheel; The other end of said fixing branch brace through connecting rod and beach buggy after reel cage be rotationally connected; Said connecting rod is with torsion spring outward, and an end of said torsion spring is fixed on behind the beach buggy on the reel cage, and the other end is fixed in the fixing branch brace.
