Description
Technical field
The utility model relates to a kind of back axle assembly of automobile, particularly a kind of back axle assembly wearing torsional vibration damper.
Background technology
The back axle assembly that current automobile is traditional, it is main subtracts bead and to be arranged in the main drive bevel gear subtracting assembly and to tighten with adjusting nut, and transmission shaft bead then directly subtracts bead with bridge end master and fits, and employing drive shaft bolt connects.The connection mode of this state makes the moment of transmission shaft transmission directly act on driving and driven finishing bevel gear cuter, causes gear to occur earlier period damage phenomenon.And along with the widespread use of integral new-energy passenger, the defect of this connection mode embodies more obvious, the instant impact that driving and driven finishing bevel gear cuter is subject to when automobile brake feedback is larger, gear cannot bear the maximum torque that motor braking produces instantaneously, the life-span of gear is reduced greatly, the requirement of integral new-energy passenger low-speed big cannot be met.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of back axle assembly wearing torsional vibration damper, so that the impulsive force making its gear be subject to is reduced to minimum, reduces the fault rate of back axle assembly critical component, improves the performance of vehicle bridge.
The technical scheme solved the problems of the technologies described above is: a kind of back axle assembly wearing torsional vibration damper, comprise axle case assy, wheel hub and brake disk assembly, semiaxis, brake assembly, compressed air brake cylinder, master subtracts assembly, master subtracts bead, transmission shaft bead, also includes torsional vibration damper; Described wheel hub and brake disk assembly are installed on axle case assy, semiaxis by bolt tightening on wheel hub and brake disk assembly, brake assembly is installed on a mounting board, compressed air brake cylinder is connected on brake assembly, master subtracts assembly and is connected with axle case assy, the main bead that subtracts is arranged on main one end subtracting assembly, and described torsional vibration damper is connected to master and subtracts in bead, and transmission shaft bead is arranged on torsional vibration damper.
Further technical scheme of the present utility model is: the ultimate torsional angle degree of described torsional vibration damper is 2 degree ~ 4 degree.
Owing to adopting said structure, the back axle assembly wearing torsional vibration damper of the utility model compared with prior art, has following beneficial effect:
1. can reduce the impulsive force of gear, reduce the fault rate of car load, improve the performance of vehicle bridge:
Because the utility model also includes torsional vibration damper, this torsional vibration damper is connected to master and subtracts in bead, and transmission shaft bead is arranged on torsional vibration damper again.Therefore, torsional vibration damper of the present utility model is bolted and is installed on back axle assembly master and subtracts in bead, the moment of transmission shaft transmission is made to directly act on torsional vibration damper, instead of directly act on driving and driven bevel gear, the impulsive force that master subtracts assembly, driving and driven bevel gear is subject to can be made to be reduced to minimum, reduce the fault rate of axle assembly critical component, not only increase master and subtract assembly in-use performance, also substantially increase the performance of vehicle bridge.Through market checking, this Novel rear axle assembly wearing torsional vibration damper, compared with traditional axle assembly, gear life improves more than 3 times, and the fault rate of car load reduces greatly.
2. maintenance cost is low, and reliability is high:
Because the utility model decreases the fault rate of car load, because this reducing the maintenance cost of vehicle bridge, improve its safety and reliability.
3. quick and easy for installation, transferable moment is large:
Because the utility model is, by bolt, torsional vibration damper is connected to main subtracting in bead, then be arranged on torsional vibration damper by bolt by transmission shaft bead, it is quick and easy for installation; And due to torsional vibration damper be adopt special substance make, its ultimate torsional angle degree is 2 degree ~ 4 degree, and transferable moment is larger.
4. structure is simple, highly versatile:
The utility model just adds a torsional vibration damper, and the structure of this torsional vibration damper is also fairly simple on common back axle assembly basis, and therefore, the utility model structure is simple, and highly versatile.
Below, in conjunction with the accompanying drawings and embodiments the technical characteristic wearing the back axle assembly of torsional vibration damper of the utility model is further described.
