Abstract
The utility model discloses a derailleur is one, including integrative spindle nose, axle body, the prism of first order, transition axle body, the prism of second order and the tail post of making, the prism of first order includes parastyle and rear pillar, parastyle afterbody and rear pillar constant diameter, anterior and the axle body constant diameter of parastyle, the parastyle rear portion is to anterior rounding off. The utility model discloses a derailleur is one on the prior art basis, divide into parastyle and rear pillar with the prism of first order of main forced section, the rear pillar sets up to the reducing, can reduce very big wearing and tearing at the operation in -process, and its global optimization manufacturing size, make its each section external diameter and length proportion can bear bigger load.
Description
Technical field
The utility model relates to an a kind of axle, and particularly a kind of speed changer one axle, belongs to technical field of automobile.
Background technique
Automotive transmission is the speed change gear of the actual travel speed of a set of rotating speed for coordinating motor and wheel, for playing the optimum performance of motor; Speed changer in vehicle traveling process, can produce different gear ratio between motor and wheel, can make engine operation under the power performance state of its best by gearshift; Speed changer is made up of variable transmission mechanism and operating mechanism, when needing, can also install power take off additional; Existing speed changer is mostly made up of preposition odd-side, main tank and box back auxiliary box; Its preposition odd-side for insert fraction, two grades, its main tank be pair jack shafts; Be arranged symmetrically with, spindle floating is installed, four forward gears, and one reverses gear; Odd-side is planetary gear construction, two grades; Wherein, two intermediate shaft structure is also called two-pack axle construction; Gearbox one axle of the prior art is easily subject to fatigue ruption; And fatigue ruption is the one of the main reasons of engineering structure and mechanical failure, the peak value causing the cyclic loading of fatigue failure is often much smaller than according to Statical pattern analytical estimating safe load out; It is worn resistance in addition is also the reason causing it to damage.
Model utility content
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of speed changer one axle, it is set to reducing by isometrical for the first post, can in running, reduce very large wearing and tearing, and optimize its manufacturing dimension, enable its each section of external diameter and length ratio bear larger load.
(2) technological scheme
Speed changer one axle of the present utility model, comprises the spindle nose, axle body, the first post, transition axle body, the second post and the stern post that are made into integration; Described first post comprises front pillar and rear pillar; Described front pillar afterbody and rear pillar isometrical; Described front pillar is anterior isometrical with axle body; Described front pillar rear portion anteriorly rounding off.
Further, described spindle nose length is 35mm, axle body length is 64.4mm, the first column length is 21.1mm, transition axis body length is 23.5mm, the second column length be 24mm and stern post length is 10.5mm.
Further, described spindle nose external diameter is 22mm, axle body external diameter is 24.5mm, transition axle body external diameter is 32.5mm, the second post external diameter be 65mm and stern post external diameter is 46.5mm.
beneficial effect
Compared with prior art, speed changer one axle of the present utility model, on prior art basis, the first post of just main forced section is divided into front pillar and rear pillar; Rear pillar is set to reducing, in running, can reduce very large wearing and tearing, and its global optimization manufacturing dimension, enable its each section of external diameter and length ratio bear larger load.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model speed changer one axle, comprises the spindle nose 1, axle body 2, first post 3, transition axle body 4, second post 5 and the stern post 6 that are made into integration; Described first post 3 comprises front pillar 7 and rear pillar 8; Described front pillar 7 afterbody and rear pillar 8 isometrical; Described front pillar 7 is anterior isometrical with axle body 2; Described front pillar 7 rear portion anteriorly rounding off.
Described spindle nose 1 length is 35mm, axle body 2 length is 64.4mm, the first post 3 length is 21.1mm, transition axle body 4 length is 23.5mm, the second post 5 length be 24mm and stern post 6 length is 10.5mm.
Described spindle nose 1 external diameter is 22mm, axle body 2 external diameter is 24.5mm, transition axle body 4 external diameter is 32.5mm, the second post 5 external diameter be 65mm and stern post 6 external diameter is 46.5mm.
Speed changer one axle of the present utility model, on prior art basis, the first post of just main forced section is divided into front pillar and rear pillar; Rear pillar is set to reducing, in running, can reduce very large wearing and tearing, and its global optimization manufacturing dimension, enable its each section of external diameter and length ratio bear larger load.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
