Abstract
The invention discloses the structure that a kind of high strength front shock absorber front fork tube is connected with vehicle body, front fork tube body (1) described in it arranges long tube body, under upper, piston rod (2) is provided with successively in front fork tube body (1), piston (3) and energy chamber, piston is provided with oil storage cylinder in (3), the top of front fork tube body (1) is provided with direction device (4), front fork tube body (1) is connected with handlebar by direction device (4), the bottom of front fork tube body (1) is connected with front vehicle wheel (6) by urceolus (5), front fork tube body (1) inserts in urceolus (5) and urceolus (5) is bearing fit.The present invention can increase safety when riding, and prevents phenomenon of rupture.
Description
Technical field
The present invention relates to the structure that a kind of high strength front shock absorber front fork tube is connected with vehicle body.
Background technology
During normal use easily there is phenomenon of rupture in the front fork tube of current front damper of motorcycle, and fracture position is substantially all in aperture, direction device lower plate bottom fulcrum location, based on riding type car, how in brake side, fracture general picture is extremely similar, because tired source is expanded mostly, crackle becomes gradually and forms breach greatly, finally ruptures instantaneously, also has now the technology adopting and increase body wall thickness in addition, but so not only add wall thickness, and reduce force of explosion when riding.
Summary of the invention
The invention provides the structure that a kind of high strength front shock absorber front fork tube is connected with vehicle body, it can increase safety when riding, and prevents phenomenon of rupture.
Present invention employs following technical scheme: the structure that a kind of high strength front shock absorber front fork tube is connected with vehicle body, front fork tube body described in it arranges long tube body, in front fork tube body by under be provided with piston rod, piston and energy chamber successively, oil storage cylinder is provided with in piston, the top of front fork tube body is provided with direction device, front fork tube body is connected with handlebar by direction device, and the bottom of front fork tube body is connected with front vehicle wheel by urceolus, and front fork tube body inserts in urceolus and urceolus is bearing fit.
Described front fork tube body is set to high-accuracy pipe.Be Full connected or part contact between the bottom of described front fork tube body and urceolus.
The present invention has following beneficial effect: the front fork tube body that the present invention adopts arranges long tube body, in front fork tube body by under be provided with piston rod successively, piston and energy chamber, oil storage cylinder is provided with in piston, the top of front fork tube body is provided with direction device, front fork tube body is connected with bearing circle by direction device, the bottom of front fork tube body is connected with front vehicle wheel by urceolus, front fork tube body inserts in urceolus and urceolus is bearing fit, the intensity of front fork tube can be improve like this, and the vibration that can greatly reduce in self car weight and wheels travel, not only meet the requirement of bicyclist for traveling comfort, and the safety increased when riding, prevent phenomenon of rupture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
In FIG, the invention provides the structure that a kind of high strength front shock absorber front fork tube is connected with vehicle body, front fork tube body 1 described in it arranges long tube body, front fork tube body 1 is set to high-accuracy pipe, the wall thickness of front fork tube body 1 be 2.5 ~ 4.5mm in front fork tube body 1 by under be provided with piston rod 2 successively, piston 3 and energy chamber, oil storage cylinder is provided with in piston 3, the top of front fork tube body 1 is provided with direction device 4, front fork tube body 1 is connected with bearing circle by direction device 4, the bottom of front fork tube body 1 is connected with front vehicle wheel 6 by urceolus 5, front fork tube body 1 inserts in urceolus 5 and urceolus 5 is bearing fit, be Full connected or part contact between the bottom of front fork tube body 1 and urceolus 5.
The preparation method of front fork tube body of the present invention comprises the following steps: step one, and select front fork tube body material, body material is 40Cr, 40Mn2 or 37Mn5, body material is made the tube body blank of front fork tube; Step 2, then the tube body blank of front fork tube is put into induction coil and carry out electro-high-frequency hardening, gap is provided with between induction coil and the tube body blank of front fork tube, straightness accuracy in electro-high-frequency hardening process should control the needs within 0.15mm/500mm, high frequency heat-treatment quenching wall thickness is 0.5 ~ 2mm, the wall thickness of front fork tube body is 2.5 ~ 4.5mm, and the tube body blank of front fork tube is carried out rotating and risen in the process of electro-high-frequency hardening, rotates and matches with the speed risen.Step 3, finally will put into the body obtaining front fork tube after cooling coil carries out tempering through hot-cured tube body blank.From the chemical composition of base pipe raw MAT'L detects, to making finished product assembling, the control of CPk value is greater than 1.33, to embody at each inter process, determine reasonably to inspect the frequency and probability statistics by random samples, set up between heat treatment sample sample, to Sample Establishing dossier, to control well batch and identify label, various list data record and archives will be determined at test session.By to induction coil, cool the adjustment in gap between induction coil, different depth subzero treatment can be obtained.
