Heavy-Duty Semi-Trailer Disc Brake Axle

Technical Field

The utility model relates to a brake axle, and in particular to a heavy-duty semi-trailer disc brake axle, belonging to the technical field related to brake axles.

Background Technology

Vehicle axles are connected to the frame or load-bearing body through suspension systems, with wheels mounted at both ends. The function of the axle is to bear the vehicle load and maintain normal vehicle operation on the road. Existing axles are generally divided into steering axles, drive axles, steering drive axles, and support axles, which themselves do not possess braking functions. Vehicles mainly rely on brake discs for wheel braking, resulting in insufficient braking reliability. This can be particularly dangerous when driving downhill and may easily cause traffic accidents. In addition, existing vehicle axles generally have poor load-bearing and shock-absorbing capabilities, which to some extent affects the overall vehicle quality.

Utility Model Content

The purpose of the utility model is to provide a heavy-duty semi-trailer disc brake axle to solve the problems mentioned above, namely that existing axles lack braking functions, rely solely on brake discs for wheel braking with insufficient reliability, pose dangers during downhill driving, and have inadequate load-bearing and shock-absorbing capacities.

To achieve the above purpose, the utility model provides the following technical solution:

A heavy-duty semi-trailer disc brake axle comprises a brake axle body. The brake axle body includes a cross beam, with wheel hubs fixedly connected to both ends of the cross beam. First grooves are formed inside both wheel hubs, and several shock absorption springs are fixedly installed inside the first grooves. Several second grooves are formed on one side of each wheel hub, and hydraulic pumps are fixedly installed inside the second grooves. The hydraulic pumps are respectively connected to friction plates through hydraulic rods. Tire mounting columns are fixedly provided on one side of each wheel hub, and threaded lines are formed at one end of each tire mounting column.

Preferred Technical Solutions

Two suspension brackets are fixedly connected to the top of the cross beam, with one suspension bracket positioned beside the other. Soft pads are fixedly arranged on the tops of the two suspension brackets.

Several fixing plates are fixedly connected to the top end of the cross beam and arranged sequentially from left to right. Threaded holes are formed on the tops of the fixing plates.

Several cooling fins are fixedly arranged on one side of each wheel hub.

A support plate is fixedly connected to the bottom of the cross beam.

The hydraulic pumps are electrically connected to the vehicle power supply through control switches inside the vehicle cab.

Beneficial Effects

Compared with the prior art, the utility model has the following beneficial effects:

The hydraulic pumps and friction plates facilitate wheel braking.

The suspension brackets support the vehicle body conveniently.

The cooling fins effectively dissipate heat from the wheel hubs.

The support plate enhances the load-bearing capacity of the heavy-duty semi-trailer disc brake axle.

Detailed Description

Referring to Figures 1–2, the utility model provides a heavy-duty semi-trailer disc brake axle comprising a brake axle body 1. The brake axle body 1 includes a cross beam 2. Wheel hubs 3 are fixedly connected to both ends of the cross beam 2. First grooves 4 are formed inside the wheel hubs 3, and several shock absorption springs 5 are fixedly installed inside the first grooves 4. Several second grooves 6 are formed on one side of each wheel hub 3, and hydraulic pumps 7 are fixedly installed inside the second grooves 6. The hydraulic pumps 7 are connected to friction plates 8 through hydraulic rods. Tire mounting columns 9 are fixedly arranged on one side of each wheel hub 3, and threaded lines are formed at one end of the tire mounting columns 9.

Preferably, two suspension brackets 10 are fixedly connected to the top of the cross beam 2. One suspension bracket 10 is positioned beside the other, and soft pads 11 are fixedly arranged on the tops of the suspension brackets, facilitating secure installation of the vehicle body while providing protection through the soft pads.

Preferably, several fixing plates 12 are fixedly connected to the top end of the cross beam 2 and arranged sequentially from left to right. Threaded holes 13 are formed on the tops of the fixing plates 12 to facilitate fixation of the vehicle body and prevent shaking during driving.

Preferably, several cooling fins 14 are fixedly arranged on one side of each wheel hub 3 to facilitate heat dissipation.

Preferably, a support plate 15 is fixedly connected to the bottom of the cross beam 2 to enhance the load-bearing capacity of the brake axle.

Preferably, the hydraulic pumps 7 are electrically connected to the vehicle power supply through control switches inside the vehicle cab, enabling convenient control of the hydraulic pumps.

Working Principle

During use, vehicle tires are first mounted onto the tire mounting columns 9 through the threaded lines at both ends. The vehicle body is then placed on the suspension brackets 10 and fixed to the brake axle using bolts and fixing plates 12. The support plate 15 fixed at the bottom of the cross beam 2 enhances the load-bearing capacity of the brake axle.

After assembly is completed, when wheel braking is required during vehicle operation, the driver presses the control switch inside the cab. The hydraulic pumps 7 drive the friction plates 8 through hydraulic rods, causing the friction plates to rub against the brake discs on the wheels, thereby braking the wheels. The shock absorption springs 5 installed inside the first grooves 4 provide excellent shock absorption performance for the brake axle.
