Description
Technical field
Multi-shaft interlocked spanner used for automobile wheels is dismounted the present invention relates to a kind of, more particularly to a kind of automobile is with four-axle linked
Spanner.
Background technology
Automobile is widely used as a kind of vehicles in current life, and spanner is used as weight during removing vehicle tyres
Instrument is wanted, is also developed rapidly, especially needs frequently to change the area of snowfield tire in northeast etc., spanner is even more that big group uses
.But each hub for vehicle wheel is fixed by multiple nuts, and general spanner can only dismount a nut every time, this results in time wave
Take, the shortcoming of inefficiency, and also have very big consumption to the muscle power of labourer, in order to meet fast assembling-disassembling, improve work effect
A kind of demand of rate, spanner that can dismount multiple nuts simultaneously is badly in need of research.
The content of the invention
In view of this, it is an object of the invention to provide a kind of multi-shaft interlocked spanner of the higher automobile of disassembly efficiency.
In order to achieve the above object, the present invention provides a kind of four-axle linked spanner of automobile, and this spanner is by panel, bottom
Plate, central gear, chain wheel formula gear, chain wheel formula output shaft, pretension screw rod, spring, pad, screw are assemblied.The panel
Identical with bottom plate form-factor, its profile is in square substantially, and two plates are assembled by screw, and the assembling that centre forms gear is empty
Between；The center of the panel and bottom plate is formed respectively with shaft hole, and panel is formed respectively with circular hole with bottom plate in four corners.Its feature
It is that central gear is gear shaft structure, axle center is formed with square hole, and gear shaft two ends are respectively fitted over the shaft hole of panel and bottom plate center
In, gear shaft stretches out in bottom plate side.The fluted disc and chain wheel of chain wheel formula gear are integrated composition, and center is equipped with through hole,
The opposite side of fluted disc has a cylinder boss, chain wheel external cylindrical surface and boss external cylindrical surface respectively with panel and the circular hole phase of bottom plate corner
Coordinate, chain wheel stretches out in panel side.The assembly space of central gear and four chain wheel formula gears between panel and bottom plate is built-in
Match somebody with somebody and engage, form a fixed shaft gear train.Chain wheel formula output shaft is formed with screwed hole, chain wheel formula output shaft in chain wheel side center
Coordinate in panels outside and chain wheel formula gear.Pretension screw rod through pad, spring, bottom plate circular hole, chain wheel formula gear center hole with
The screwed hole of chain wheel formula output shaft coordinates, and both ends of the spring is press respectively against on the cylinder boss of pad and chain wheel formula gear.
Further, the reference diameter of the central gear is less than the reference diameter of surrounding chain wheel formula gear, this
Configuration can improve moment of torsion, and gear shaft centre bore can be the hole of the other shapes in addition to square.
Further, the center of four chain wheels formula gear is on a pitch circle, pitch diameter and automobile wheel hub bolt
The pitch diameter in hole is identical.
Further, the pretension bolt meets condition of self-locking with chain wheel formula output shaft screw thread pair, i.e., when not by external force,
Pretension bolt will not be screwed out automatically.
Further, the tooth form cross section of chain wheel formula output shaft and chain wheel the formula gear is isosceles trapezoid, and each tooth is in umbrella
Shape radiation profiles, facing has certain angle of inclination, occlusal contact area after chain wheel cooperation is successively decreased by four circumferential centers.
The beneficial effect that the present invention reaches is：1st, multiple nuts can be dismounted simultaneously, and will not produce what moment of torsion diminished
Problem, improves operating efficiency.2nd, pretightning force can be adjusted by adjusting pretension bolt, reaches the purpose for determining torque output.
3rd, it can coordinate with pneumatic impact spanner on the market, without separately putting power source, structure is relatively simple, and cost is not high, market adaptability
By force.
Brief description of the drawings：
Fig. 1 is the three-dimensional exploded view of automobile tetrad wrench；
Fig. 2 is the three-dimensional combination figure of automobile tetrad wrench；
Fig. 3 is the schematic diagram of chain wheel formula gear.
In figure：1 panel；2 bottom plates；3 central gears；4 chain wheel formula gears；5 chain wheel formula output shafts；6 pretension bolts；7
Spring；8 pads；9 screws.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail：
Tetrad wrench as shown in Figure 1, including bottom plate 1, panel 2, central gear 3, chain wheel formula gear 4, chain wheel formula output shaft
5th, pretension bolt 6, spring 7, pad 8 and screw 9, panel 1 are identical with the form-factor of bottom plate 2, and its profile is in square substantially,
Two plates are assembled by screw 9, and centre forms the assembly space of gear；The center of panel 1 and bottom plate 2 is formed respectively with shaft hole, face
Plate 1 is formed respectively with circular hole with bottom plate 2 in four corners.Central gear 3 is gear shaft structure, and axle center is formed with square hole.Chain wheel formula tooth
The fluted disc and chain wheel of wheel 4 are integrated composition, and center is equipped with through hole, has cylinder boss in the opposite side of fluted disc.Central gear 3
And four chain wheel formula gears 4 are assembled and engaged in the assembly space between panel 1 and bottom plate 2.Chain wheel formula output shaft 5 is in chain wheel side
Center is formed with screwed hole.Pretension screw rod 6 passes through pad 8, spring 7, bottom plate circular hole, chain wheel formula gear center hole and chain wheel formula
The screwed hole of output shaft coordinates, and the two ends of spring 7 are press respectively against on the cylinder boss of pad 8 and chain wheel formula gear.
In use, first passing through regulation pretension bolt to adjust the pressure force of chain wheel, so as to control output torque, regulate
Afterwards, the output shaft of pneumatic impact spanner or other power sources is inserted in the square opening of central gear 3, central gear 3 is rotated simultaneously
Chain wheel formula gear 4 around driving is rotated, and chain wheel formula gear 4 is rotated by chain wheel mating band movable chain wheel formula output shaft 5, so that real
Existing bolt, the assembly and disassembly of nut.
It is that chain wheel formula gear 4 and chain wheel formula gear 5 can be disengaged, shape when output torque is more than nominal torque set in advance
Into idle running, it is ensured that maximum output torque.Because the reference diameter of central gear 3 is less than the reference circle of chain wheel formula gear 4
Diameter, so in the case where power source output torque is constant, final output torque still can be ensured.
According to different wheel models, we can accordingly make the multi-joint wrench of different model；Above-described embodiment is used for
The present invention is illustrated, rather than present aspect is limited, it is right in the protection domain of spirit and claims of the present invention
Any modifications and changes that present aspect is made, both fall within protection scope of the present invention.
