Description
The utility model relates to a kind of wheel instrument of tearing open that is used for automobile.
Automotive wheel is by several nuts wheel to be fixed tightly on the axletree, tightens or unclamps a nut, and according to varying in size of car, the force that is spent is also different, if with spanner dismounting nut, the power that needs are very big.General small passenger car needs tens kilograms at least, tens kilograms of compact car needs, and some full-sized cars not only need to use big spanner, but also to overlap upper bush, so that whole people will stand on the sleeve power that needs are up to a hundred kilograms.
In Chinese patent application number is to disclose name in 91228169.3 to be called " tube lifter ", and its structure includes a body, protecgulum, bonnet, first driver element, second driver element, transmission component and align member.During use, earlier the collet head on second driver element is sheathed on wheel and goes up on the nut of desire dismounting, to make align member withstand between body and the ground, the application of force makes the rotation of first driver element then, drive the rotation of second driver element by transmission component, the nut on the wheel can be unscrewed.Its transmission component mainly is to adopt planetary gear construction, this structure is because revolution ratio is little, arrive certain revolution ratio, the number of teeth of inevitable gear will increase, if the number of teeth is too many, under the certain condition of gear diameter, the force intensity that is subjected to of tooth can reduce, unless the increasing gear size, so corresponding volume also can increase.In addition for preventing the body rotation, on body, be provided with a location member, nut of every dismounting is all different according to the seat height of nut on wheel, from newly controlling align member, or the length of regulating align member, the ground soft or hard that adds upper support differs, and is uneven, the adjusting of align member is comparatively frequent, uses to seem inconvenient.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of driving efficiency height is provided, and converter speed ratio is big and volume is little, and the single head that intensity is high is manually torn the wheel instrument open.
For realizing the purpose of this utility model, this single head is manually torn the wheel instrument open and is included a housing, input actuator, output actuator, middle part at described input actuator is provided with eccentric cylinder, being with on described eccentric cylinder can be around the external arc gear of eccentric cylinder rotation, the output actuator is provided with and takes off post, correspondence is provided with the connection circular hole that is enclosed within on taking off post on the circular-arc gear outside, housing is provided with interior circular-arc gear, described external arc gear and the engagement of interior circular-arc gear, supporting handle is arranged on the housing, on described supporting handle, be provided with the strut member of an activity.
The drawing of accompanying drawing is described as follows:
Fig. 1 manually tears the constructional drawing of wheel instrument open for the utility model single head.
Fig. 2 is the B-B cutaway view among Fig. 1.
Fig. 3 is the A-A cutaway view among Fig. 2.
Below in conjunction with accompanying drawing, the utility model single head is manually torn open one of them embodiment of wheel instrument is described in further detail:
As shown in fig. 1, single head is manually torn the wheel instrument open, includes a housing (1), input actuator (2), output actuator (3), external arc gear (5), interior circular-arc gear (6), supporting handle (7), strut member (8).Tooth on external arc gear (5) and the interior circular-arc gear (6) is the cycloid curved tooth.External arc gear (5) center is provided with axis hole.Housing (1) and supporting handle (7) are an integral structure, are provided with interior circular-arc gear (6) on housing (1), interior circular-arc gear (6) directly and housing (1) be made for one, be arranged in the housing (1) after also can making separately.Input actuator (2) is one cylindric, is arranged in the front-axle hole (14) of housing (1).Its outer portion part that is exposed at housing (1) is a tetragonal prism, is convenient to spanner and blocks rotation.At least being provided with an eccentric cylinder (4) on the inner section of its housing (1), two sections eccentric cylinders (4) of eccentric throw such as is in Fig. 1.External arc gear (5) is enclosed within on the eccentric cylinder (4), can rotate around eccentric cylinder (4), and mesh with external arc gear (5), owing on two eccentric cylinders (4), all be with external arc gear (5), and symmetry and interior circular-arc gear (6) engagement make input actuator (2) be in the center balance position all the time.In addition, because the inner termination (17) of input actuator (2) is arranged in output actuator (3) centre hole (18), make an end of input actuator (2) and output actuator (3) be individually fixed in the front-axle hole (14) of housing (1) and the back axis hole (15) and the mutual socket of the other end, connect solidly, compact, improved driving efficiency.Output actuator (3) is arranged in the back axis hole (15) of housing (1), is in housing (1) outside at it and is tetragonal prism, is convenient to connect with sleeve, the dismounting nut.There is a disk (16) its inside that is in housing (1), on disk (16), be provided with six take off post (12) apart from the equidistant R of its axial line, as shown in Fig. 2,3, circular-arc gear (5) is also corresponding outside is provided with six connection circular holes (13) apart from the equidistant R of its axial line.When the input actuator rotates, by eccentric cylinder eccentric rotary thereon, thereby drive the also eccentric rotation of external arc gear, make the external arc gear around the motion of the tooth limit of interior circular-arc gear, the input actuator whenever revolves and turns around, the external arc gear only turns over a tooth, drives to take off post by the connection circular hole on the external arc gear disk on the output actuator is rotated, thereby makes whole output actuator rotation.Its revolution ratio=external arc gear number of teeth/(the interior circular-arc gear number of teeth-external arc gear number of teeth).For housing (1) can not rotated, and the wheel of moving fulcrum with the vehicle that adapts to various models arranged, on supporting handle (7), be provided with a microscler sliding eye (9), the part of strut member (8) in supporting handle (7) is a cylindric supporting revolving shaft (11), on supporting revolving shaft (11), be provided with an inner bolt hole, strut member (8) is provided with a fastener (10), and fastener (10) is a screw, can with supporting revolving shaft (11) thread connection on the described strut member (8).When the nut on the removing vehicle tyres, on output actuator and strut member, overlap upper bush respectively, regulate the position between strut member and the output actuator, make two sleeves all be enclosed within on the nut of wheel, screw screw, strut member is fixed on the supporting handle, has so just utilized the relative fixed position of two nuts, make housing can not rotate.
The utility model single head hand wheel removing tool makes it and interior circular arc owing to adopt by eccentric cylinder driving external arc gear The gear engagement is rotated and the driver output actuator, and rotating ratio is big, and transmission component mainly is by external arc gear and interior wildhaber-novikov gear Consist of, simple in structure, the efficient height, structural strength is big. And whole housing is to be undertaken by supporting handle and the support member on it The location, have and use lightly, laborsaving, compact conformation, simple, easy to use, dismounting be advantage efficiently.
