According to the heavy-duty car double-stage speed-reducing steering axle, the braking moment can be improved and the braking performance requirements of certain special engineering vehicles are met; and the heavy-duty car double-stage speed-reducing steering axle has the advantages of compact structure, small volume and convenience in maintenance.
Description
Technical field
The utility model relates to the heavy motor vehicle parts, is specifically related to
OnePlant the heavy motor vehicle dual-ratio reduction steeraxle with the hydraulic tongs brake device.
Background technology
The dual-ratio reduction steeraxle of heavy motor vehicle in use needs to bear larger load, and larger transmitting ratio and larger ground Clearance need to be arranged, and often adopts the dual-ratio reduction mode on the drive mechanism, and namely main reduction gear adds wheel reduction gear.What mostly install on the present this heavy motor vehicle dual-ratio reduction steeraxle is the cam-type drum brake mechanism.The demand of heavy engineering vehicle begins rapid increase at present, because engineering truck deadweight and load-carrying are all very large, and the road shape is poor, requirement to deceleration and stopping performance also improves a lot, and camshaft type drum brake commonly used can not satisfy some special vehicle to the requirement of deceleration and stopping performance, and its deficiency is mainly as follows: (1) lock torque less; (2) structure relative complex, number of parts is more, and spatial volume is large, is difficult for carrying out the chassis and arranges.Therefore, existing heavy motor vehicle dual-ratio reduction steeraxle requires further improvement.A kind of drg can improve lock torque, satisfies the deceleration and stopping performance requirement of some special engineered vehicle.
Summary of the invention
The purpose of this utility model has provided a kind of heavy motor vehicle dual-ratio reduction steeraxle with the hydraulic tongs brake device, and it can improve lock torque, satisfies the deceleration and stopping performance requirement of some special engineered vehicle, compact conformation, and volume is little, is convenient to safeguard.
The utility model is achieved through the following technical solutions:
A kind of heavy motor vehicle dual-ratio reduction steeraxle with the hydraulic tongs brake device comprises the dual-ratio reduction drive axle, and it is characterized in that: the both ends at described dual-ratio reduction drive axle are provided with respectively the hydraulic tongs brake device;
The semiaxis that the main reduction gear, an end that described dual-ratio reduction steeraxle comprises axle housing, be located at the axle housing middle part and main reduction gear are connected, be connected with the axle housing end and the steering swivel that is connected with the other end of semiaxis, the wheel hub that is connected by hub bearing and steering swivel, be located at the wheel reduction gear on the wheel hub by stub; The brake clamp of described hydraulic tongs brake device and steering swivel are connected and fixed by the first bolt; The brake disc of described hydraulic tongs brake device and wheel hub are connected and fixed by the second bolt.
The utility model has been owing to adopted hydraulic caliper-disc brake, so, compact conformation, volume is little, and lock torque is large, and insensitivity is high, can independently realize automatically adjusting braking gap, can effectively avoid the bad phenomenon such as braking heating, locking.The utility model is to select the hydraulic tongs brake device under the prerequisite that guarantees heavy motor vehicle dual-ratio reduction steeraxle power-handling capability and load-carrying capacity, this drg is applicable to the special engineered vehicle bridge of all kinds of heavy types, adapt to various open-air road surfaces, improved the deceleration and stopping performance of heavy axle.
Description of drawings
Fig. 1 is part sectional view of the present utility model;
Fig. 2 is outside drawing of the present utility model;
Fig. 3 is the constructional drawing of hydraulic tongs brake device;
Fig. 4 is the left view of Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1 and Fig. 2, a kind of heavy motor vehicle dual-ratio reduction steeraxle with the hydraulic tongs brake device comprises the dual-ratio reduction drive axle, is provided with respectively the hydraulic tongs brake device at the both ends of described dual-ratio reduction drive axle;
The semiaxis 12 that the main reduction gear 11, an end that described dual-ratio reduction steeraxle comprises axle housing 1, be located at the axle housing middle part and main reduction gear are connected, be connected with axle housing 1 end and the steering swivel 2 that is connected with the other end of semiaxis 12, the wheel hub 6 that is connected by hub bearing 10 and steering swivel 2, be located at the wheel reduction gear 8 on the wheel hub 6 by stub 9;
Brake clamp 3 and the steering swivel 2 of described hydraulic tongs brake device are connected and fixed by the first bolt 4; Brake disc 5 and the wheel hub 6 of described hydraulic tongs brake device are connected and fixed by the second bolt 7.
Referring to Fig. 3 and Fig. 4, what the utility model adopted is the hydraulic caliper-disc brake of common structure, and it mainly is comprised of brake clamp 3, brake disc 5 etc.Piston compresses brake clamp 3 and brake disc 5 under the effect of hydraulic oil during braking, thereby the generation friction moment makes car retardation or parks.
The utility model transmission, braking principle are as follows: power passes to wheel reduction gear 8 by main reduction gear 11 through semiaxis 12, drives brake discs 5 by wheel hub 6 and rotates.Piston compresses the generation friction force with brake clamp 3 and brake disc 5 during braking under the effect of hydraulic oil, reaches braking effect thereby this friction force makes brake disc 5 and wheel reduction gear 8 stop transhipment.
Along with the great development of domestic mine railway, the demand of heavy engineering vehicle also begins rapid increase.Because engineering truck deadweight and load-carrying are all very large, and the road shape is poor, requirement to deceleration and stopping performance also improves a lot, hydraulic tongs brake device lock torque is large, be a kind of drg that can improve present heavy engineering vehicle braking performances, it will be used widely at special engineered vehicular field.
