Description
Technical field
The utility model belongs to the Manufacturing Technology for Automotive Parts field, specially refers to the structure of differential mechanism.
Background technique
Differential mechanism is made up of parts such as planetary pinion, planetary wheel carrier (being differential casing), differential gears, and the power of motor enters differential mechanism through transmission shaft, directly drives planetary wheel carrier, drives left and right two semiaxis by planet wheel again, drives left and right wheel respectively.As shown in Figure 1, 2, in traditional differential assembly, planet pin (2) carries out axially locating by a columniform fixing pin (4), differential casing (1) utilizes bolt (3) to come to be connected with component such as differential gear, one pin-and-hole (5,6) is respectively arranged on differential casing (1) and the planet pin (2), and fixing pin (4) is squeezed into the axial motion that pin-and-hole (5,6) back just can restrictions planetary gear axle (2).For prevent that fixing pin from dropping out in automobile is advanced, must carry out the riveting envelope to the aperture of pin-and-hole (5).Above-mentioned limit method more complicated to planet pin causes that installation time is long, labor intensity is big, purchase cost is high, and riveted joint place in fixing pin and aperture damages easily, and reliability is low.
The model utility content
First purpose of the present utility model is to propose a kind of limiting board.
The key of limiting board of the present utility model is that this limiting board comprises base plate and the side plate that is positioned at the base plate side, and described side plate protrudes in base plate, and described base plate is provided with bolt hole.
In use, this limiting board utilization is bolted on the housing of differential mechanism, the side plate of limiting board and the planet pin of differential mechanism offset, axial motion that so just can the restrictions planetary gear axle, compare and utilize fixing pin to fix the means of fixation of planet pin, the installation of limiting board has reduced riveting step, has saved installation time, assembles convenient, reliable.Because need on differential casing and planet pin, not beat pin-and-hole, can prolong the working life of housing and planet pin, thereby reduce purchase cost and maintenance cost in addition.
Stressedly when guaranteeing that limiting board fixedly evenly avoid the side plate unbalance stress and cause bending, described bolt hole is at least two, and is evenly distributed on the two ends of side plate.
Described base plate and side plate integrated punching form, and be not only convenient for production, can also guarantee the structural strength of limiting board.
Second purpose of the present utility model is the differential mechanism that proposes to be equipped with above-mentioned limiting board.
The differential mechanism that above-mentioned limiting board is housed of the present utility model comprises differential casing, differential gear and planetary pinion, described planetary pinion is connected with housing by planet pin, described housing has the mounting hole that passes for planet pin in the position of corresponding planet pin, key is that described limiting board utilizes bolt to be installed on the housing in the mounting hole outside, and the side plate and the planet pin of limiting board offset.
The spacing of described limiting board bolt hole is consistent with the spacing and the diameter of the bolt hole of the fixedly differential gear of differential casing with diameter, the described limiting board utilization fixedly bolt of differential gear is installed on the two ends of the planet pin mounting hole of housing, so just can utilize the bolt of the original fixedly differential gear of differential casing that limiting board is fixed, need not to redesign differential casing, and can save bolt quantity and installation time.
Limiting board of the present utility model is simple in structure, easy for installation, be assemblied in the axial motion that can effectively prevent differential spider pinion shaft on the differential casing, compare traditional fixation method and not only improved efficiency of assembling, also prolong the working life of housing and planet pin, saved buying and maintenance cost.
