Description
Technical field:
The utility model relates to passenger vehicle parts technical field, is a kind of novel main reduction gear that adopts the friction wheel transmission concretely, is applicable to low moment of torsion passenger vehicle vehicle bridge.
Background technology:
Along with developing of automobile industry, also more and more higher to the various performance demands of motor passenger vehicle, particularly also more and more stricter to the requirement of noise, and the present used vehicle bridge of motor passenger vehicle is based on traditional gear transmission, mainly contain following deficiency: 1, gear transmission noises is subjected to working accuracy, it is big that influence is adjusted in assembling, bad control; 2, the Gear Processing cost is higher; 3, a pair of driving and driven bevel gear engagement flower wheel size is big, and the ground Clearance is little, and crossing ability is poor.
Summary of the invention:
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of novel main reduction gear is provided, and mainly solves existing vehicle bridge main reduction gear and is subjected to working accuracy to influence the problem of the bad control of noise, Gear Processing cost height and crossing ability difference.
In order to achieve the above object, the utility model is achieved in that a kind of novel main reduction gear, it comprises bead 1, its special character is that bead 1 is connected with active friction wheel I2, active friction wheel I 2 is connected with cylindrical wheel 3 respectively by spline with active friction wheel II 4, cylindrical wheel 3 is a pair of cylindrical gear pair, active friction wheel I 2 is connected with two end faces of driven friction wheel 5 with active friction wheel II 4, driven friction wheel 5 is connected with planetary wheel 8 with center cross 7 by the male splines on the differential left shell 6, planetary wheel 8 is connected with semiaxis 10 with axle side gear 9, on bead 1, establish adjustment nut 11, between adjustment nut 11 and active friction wheel I2 and active friction wheel II4, establish compression spring 12 respectively.
Compared with the prior art a kind of novel main reduction gear described in the utility model has following good effect: 1, adopt frictional transmission to substitute traditional gear transmission, adopt two driving wheels to substitute traditional single capstan, thereby reduced rotational noise, improved the ground Clearance; 2, tooling cost is low; 3, highly versatile.
Description of drawings:
Fig. 1-structural representation of the present utility model.
The specific embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe a kind of novel main reduction gear of the utility model in detail.
Embodiment 1, referring to Fig. 1, be processed into bead 1, active friction wheel I 2 is connected with bead 1, again with active friction wheel I 2 and active friction wheel II 4 by spline respectively with cylindrical wheel 3, cylindrical wheel 3 is a pair of cylindrical gear pair, then active friction wheel I 2 is connected with two end faces of driven friction wheel 5 with active friction wheel II 4, driven friction wheel 5 is connected with planetary wheel 8 with center cross 7 by the male splines on the differential left shell 6, left and right sides differential casing passes through Bolt Connection, planetary wheel 8 is connected with semiaxis 10 with axle side gear 9, adjustment nut 11 is installed on bead 1 at last, between adjustment nut 11 and active friction wheel I 2 and active friction wheel II 4, compression spring 12 is installed respectively.
A kind of novel main reduction gear described in the utility model, in the course of the work, the moment of torsion that driving engine provides is delivered to active friction wheel I and cylindrical wheel (a pair of cylindrical gear pair) by bead, power is delivered to active friction wheel II through the shunting of cylindrical wheel, active friction wheel I and active friction wheel II collaborate power and are delivered to driven friction wheel, connect (left and right sides differential housing passes through Bolt Connection) by the male splines on the differential left shell transmission of power is arrived center cross and planetary wheel, planetary wheel arrives axle side gear and semiaxis with transmission of power again, thereby transfer torque to wheel, drive wheels is advanced.
When the wearing and tearing of active friction wheel and driven friction wheel produced the gap, compression spring can guarantee that automobile has enough propulsive efforts by automatic compensation gap, when the gap greatly when causing the propulsive effort deficiency, can regulate adjustment nut adjustment.
