Description

The General Motors drive axle assembly of equipment ABS

Technical field

The utility model relates to a kind of improvement of General Motors drive axle assembly, and specifically a kind of General Motors drive axle assembly of equipping ABS mainly is applicable to General Motors.

Background technology

The drive axle assembly is one of major critical component on the automobile, in normal vehicle ', often because of road surface problem and traffic cause brake system to break down traffic accident takes place.The employing brake regulation system can improve the distribution at each wheel in brake system, but can't avoid wheel lockup, in case locking all will make deceleration and stopping performance reduce, automobile loses steering capability or forfeiture vehicle run stability.ABS is a kind of anti-block braking system of car, (Anti-lock Brakesystem, be called for short ABS), be according to pairing tire under the different slip rates---ground-surface attachment characteristic is regulated the brake system of car of braking force, it makes brake wheel make full use of ground attaching coefficient and obtains higher ground braking force and side force, shorten the stopping distance of automobile, obtain direction operational stability preferably.At present at home, all be used widely on outer high-grade car and the high-grade truck, but also being in initial stage of development on general General Motors, differs in installation method and position, and the effect that obtains also has than big-difference.

Summary of the invention

The purpose of this utility model be to provide a kind of installation site convenient, simple, can significantly reduce wheel slip and improve automobile brake perfrmance, be exclusively used in the General Motors drive axle assembly of the equipment ABS on the General Motors.

For reaching above purpose, the technical scheme that the utility model adopted is: the General Motors drive axle assembly of this equipment ABS, by Hub assembly, axle case assy, brake assembly, main gearbox assembly, the semiaxis assembly constitutes, Hub assembly and axle case assy, the semiaxis assembly, connection between the main gearbox assembly is prior art, it is characterized in that in the inner of Hub assembly fixedly upper ring gear, brake support plate in the working direction rearward position, the semiaxis flange, the fixing fixed support of going up speed sensor in the inner of the bolt of rear end plate that the axle housing flange is connected, the speed sensor of abs sensor is fixed in the fixed support, the induction head end of speed sensor withstands on the flank of tooth of gear ring, the tail end of speed sensor is pulled out the conduction cable, the fixing plug that is connected with the ECU computing machine of going up in the outer end of conduction cable.The utility model is also implemented by following measure: mesh lining on the suit of the speed sensor outside of abs sensor, scribble the automobile specified grease layer in the mesh of mesh lining, the axis of the speed sensor of abs sensor is vertical with the flank of tooth of gear ring; Establish the step interface on the inner pipe of Hub assembly edge, the inner hole sleeve of gear ring is contained on the step interface fixing; Described gear ring is circular, and its diameter of bore is 140mm, and to be advisable on the step interface that just in time is sleeved on Hub assembly the inner, the external diameter of gear ring is 158mm, and thickness is 12.5mm, and the number of teeth is 80 teeth; The support bracket fastened outer end of described speed sensor is a tubular, so that the insertion speed sensor, the inner is the permanent seat of bolt of rear end plate; Described mesh lining is a tubular, is provided with the circular hole of netted arrangement on its barrel; Described abs sensor is a prior art, during use, the plug of speed sensor by conduction cable outer end is connected with the ECU computing machine, the ECU computing machine is connected with electromagnetic valve again, by the rotating speed of different wheel control gear ring, the signal of gear ring reaches the ECU Computer Processing by speed sensor and conduction cable, and processing signals is control electromagnetic valve again, and then control brake air chamber, act on brake facing by brake line again.

The beneficial effects of the utility model are: compare with the drive axle assembly that uses on the present General Motors, owing in the drive axle assembly, equipped abs sensor, this sensor has the anti-lock function, utilize little power technology control brake system, thereby reduce the slip rate of wheel, improve deceleration and stopping performance, avoid the train operation accident that occurs because of locking, guarantee personal safety, and install easily, be convenient to operate, be difficult for breaking down.
