Abstract
Description
Technical field:
The utility model relates to the drive axle that uses on a kind of self-propelled vehicle, is specifically related to a kind of constant-velocity universal joint drive axle of one independent suspension.
Background technology:
Drive axle is the important motivity driving device that uses on the self-propelled vehicle, and its effect mainly is that the output torque with main speed reduction box is delivered to drive wheels.Traditional float amount RV recreational vehicle drive axle is only formed by an axle drive shaft, this structural limitations the terrain clearance of car load and the off-road capability under the bad working environments.Form constant velocity universal joint drive spindle through the improvement back, this constant speed universal joint drive spindle mainly is made up of constant-velocity universal joint, tween drive shaft and axial displacement constant-velocity universal joint, constant-velocity universal joint and axial displacement constant-velocity universal joint are installed in the two ends of tween drive shaft respectively, constant-velocity universal joint connects wheel hub, axial displacement constant-velocity universal joint and reverse gear, axle housing etc. assemble, black box after the assembling forms constant-velocity universal joint drive axle, complex structure, cost height.
The utility model content:
In order to overcome existing constant-velocity universal joint drive axle complex structure and the high deficiency of cost, the utility model provides a kind of constant-velocity universal joint drive axle of one independent suspension, this drive axle simplifies the structure, and has reduced cost, has improved the terrain clearance of car load and the off-road capability under the bad working environments.
The technical solution of the utility model is: the constant-velocity universal joint drive axle of this one independent suspension comprises constant-velocity universal joint and tween drive shaft, one end of tween drive shaft is installed constant-velocity universal joint, also include disc brake dish chain pulley seat, the two ends of disc brake dish chain pulley seat are provided with through hole for " dish " and centre, described through hole two ends all are equipped with retainer, steel ball and inner race, and the other end of tween drive shaft is installed in the described inner race.
Described steel ball is spacing by the oral area back-up ring, and the end of tween drive shaft is spacing by axle-steel silk back-up ring.
The two ends of described disc brake dish chain pulley seat are equipped with dust boot.
One end of described dust boot is stuck in the disc brake dish chain pulley seat by back-up ring, and the other end of dust boot is stuck on the tween drive shaft by clip.
The two ends of described disc brake dish chain pulley seat connect propulsion source and brake disc respectively.
One end of described disc brake dish chain pulley seat is fixed with sprocket wheel, is chain-driving between disc brake dish chain pulley seat and the change speed gear box.
The utlity model has following beneficial effect: owing to take such scheme, retainer, steel ball and inner race are installed in the intermediate throughholes two ends of disc brake dish chain pulley seat, form two axial displacement constant-velocity universal joints shared " clutch can ", again moment of torsion has directly been passed to two tween drive shafts respectively by disc brake dish chain pulley seat.The utility model and background technology simplified in comparison structure, reduced cost, improved the terrain clearance of car load and the off-road capability under the bad working environments.
Description of drawings:
Accompanying drawing 1 is a structure cutaway view of the present utility model.
1-constant-velocity universal joint among the figure, 2-tween drive shaft, 3-disc brake dish chain pulley seat, 4-through hole, 5-retainer, 6-steel ball, 7-inner race, 8-oral area back-up ring, 9-axle-steel silk back-up ring, 10-dust boot, 11-back-up ring, 12-clip.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the constant-velocity universal joint drive axle of this one independent suspension comprises constant-velocity universal joint 1 and tween drive shaft 2, one end of tween drive shaft 2 is installed constant-velocity universal joint 1, also include disc brake dish chain pulley seat 3, the two ends of disc brake dish chain pulley seat 3 are provided with through hole 4 for " dish " and centre, described through hole 4 two ends all are equipped with retainer 5, steel ball 6 and inner race 7, and the other end of tween drive shaft 2 is installed in the described inner race 7.Retainer 5, steel ball 6 and inner race 7 are installed in the intermediate throughholes two ends of disc brake dish chain pulley seat 3, disc brake dish chain pulley seat 3 is equivalent to " clutch can ", form two axial displacement constant-velocity universal joints shared " clutch can ", again moment of torsion has directly been passed to two tween drive shafts 2 respectively by disc brake dish chain pulley seat 3.The utility model and background technology simplified in comparison structure, reduced cost, improved the terrain clearance of car load and the off-road capability under the bad working environments.Because the moving velocity of RV recreational vehicle is not high, and mainly is to travel on the rugged in the open air road conditions, for cost-cutting and simplified structure, the utility model has been cancelled the setting of diff.
Described steel ball 6 is spacing by oral area back-upring 8, and the end of tween drive shaft 2 is spacing by axle-steel silk back-up ring 9.Simple in structure, easy to assembly, cost is low.
The two ends of described disc brake dish chain pulley seat 3 are equipped with dust boot 10.Dust boot 10 can prevent that dust, earth etc. from entering in the disc brake dish chain pulley seat 3.
One end of described dust boot 10 is stuck in the disc brake dish chain pulley seat 3 by back-up ring 11, and the other end of dust boot 10 is stuck on the tween drive shaft 2 by clip 12.Dust boot 10 has certain elasticity, can be with tween drive shaft 2 axial stretchings, to adapt to rugged harsh environment.
The two ends of described disc brake dish chain pulley seat 3 connect propulsion source and brake disc respectively.Moment of torsion is directly delivered to disc brake dish chain pulley seat 3, and disc brake dish chain pulley seat 3 is rotated, and drives tween drive shaft 2 rotations to the greatest extent; Brake disc is directly installed on an end of disc brake dish chain pulley seat 3, has also simplified brake system.
One end of described disc brake dish chain pulley seat 3 is fixed with sprocket wheel, is chain-driving between disc brake dish chain pulley seat 3 and the change speed gear box.Each parts accuracy requirement of chain-driving is low, is convenient to assembling, effectively cost-cutting.
