Description
Technical Field
The invention relates to the field of vehicle engineering, in particular to a trailer axle system with a hydraulic retarder.
Background
With the rapid development of automobile industry in China, the road transportation proportion of road transportation is increased year by year, and the road transportation proportion becomes a main road transportation mode in China. In mountainous areas with abundant resources and busy docks, the transportation of goods is basically realized by medium-sized transport vehicles. The carrying trailer has the advantages of high loading rate, strong bearing capacity, less configuration for drivers, low labor cost, low logistics cost, high intensification and the like, so that the carrying trailer occupies a great position in long-distance transportation of goods.
However, as the number of carrying trailers increases in the transportation of goods, the traffic accidents on roads also increase. The carrying trailer bears the weight, has large volume and large inertia, and often causes great loss of life and property of people once a car accident happens. Among these traffic accidents, a large percentage of traffic accidents occur due to the failure of the brakes of the carrying trailer. The carrying trailer often encounters a long downhill slope in the long-distance transportation process, a driver needs to frequently step on a brake pedal, friction between a brake shoe and a brake drum frequently occurs, the temperature is increased, and the abrasion is increased. If the brake shoes and brake drum are often operated in such an environment, the brake system carrying the trailer is susceptible to brake failure. The requirement of safe speed reduction of the carrying trailer cannot be met by only depending on the friction between the brake shoes and the brake drum, so a retarding auxiliary brake device is required to be adopted for the safe speed reduction of the carrying trailer in a long downhill.
The retarding efficiency of the hydraulic retarder in the prior art is higher than that of an engine retarding device, and the hydraulic retarder can run downhill at a higher speed; the size and the mass are small, and the transmission can be connected with the transmission into a whole; no abrasion is generated during working; the heat generated by the working liquid is easy to transfer and dissipate, and the normal working temperature of the engine can be maintained when the engine runs down a long slope; the braking torque tends to zero at low speed, and the wheels do not slip during the road brake. However, the hydraulic retarder has long engaging and disengaging lag time, has power loss when not in operation, and has a complex structure when being used for a mechanical transmission automobile, particularly a freight trailer. Generally, the hydraulic retarder can be installed between an engine and a transmission and also can be installed behind the transmission, the retarder with the two structures needs a special gearbox to be matched with the hydraulic retarder for use, not only is the arrangement of the whole vehicle influenced, but also the rear suspension of the engine is influenced, and the reliability and the durability are poor. In the case of a truck trailer, the longer body of the truck trailer has a greater deadweight, and the two forms reduce the driving stability of the truck during emergency braking, which is not the best option.

Detailed Description
As shown in fig. 1 to 4, the trailer axle system provided with the hydraulic retarder device comprises two non-driven axles 1 on a trailer and a double-rotor hydraulic retarder device 2 arranged between the two non-driven axles 1, so that the space between the two non-driven axles 1 can be effectively utilized without influencing the weight bearing effect of the trailer. Main reducers in two non-driven axles 1 are respectively connected to two sides of a double-rotor type hydraulic retarding device 2 through a transmission mechanism 3, power of a half shaft in the non-driven axle 1 is transmitted to the double-rotor type hydraulic retarding device 2, accordingly, the two non-driven axles 1 form a double-link axle, and the effect of retarding braking is achieved by means of interaction between the two non-driven axles 1. The transmission mechanism 3 in this embodiment includes a transmission shaft 301 and an input shaft 302, one end of the transmission shaft 301 is connected to a half shaft in a main speed reducer in the non-drive axle 1 through a bevel gear set, and the other end is connected to the input shaft 302 through a universal joint 303, and the input shaft 302 transmits power of the half shaft in the axle to the double-rotor type hydraulic retarder 2. Since the twin rotor type hydraulic retarder 2 is provided between the two drive axles 1, the rotational directions of the two power transmission input shafts 302 are opposite to each other. The arrangement of the universal coupling 303 in this embodiment can avoid the influence caused by the radial displacement between the two input shafts 302 due to the relative position change of the two non-driving axles 1 in the trailer driving process. One end of one of the two input shafts 302, which is far away from the dual-rotor type hydraulic retarder 2, is provided with a spline, a spline shaft 304 is arranged on the corresponding universal coupling 303, the spline shaft 304 is connected with one end, provided with the spline, of the input shaft 302 through a spline sleeve 305, a gap is reserved between the spline shaft 304 and one end, provided with the spline, of the input shaft 302, and the spline shaft 304 and the end, provided with the spline, of the input shaft 302 can slide in the spline sleeve 305 along the axial direction, so that the influence caused by the axial displacement generated between the two input shafts 302 due to the change of the relative positions of the two non-drive axles 1 in the running process of the trailer can be avoided.
The double-rotor type hydraulic retarder 2 comprises a machine shell 201 fixed on a trailer frame, a double-rotor type hydraulic coupler 4 arranged in the middle of the interior of the machine shell 201, two speed-increasing and torque-reducing mechanisms 5 and two clutch mechanisms 6 symmetrically arranged on two sides of the double-rotor type hydraulic coupler 4. The double-rotor fluid coupling 4 includes an annular oil chamber 401 and two rotors 402 disposed in the annular oil chamber 401 in opposition. Buffer oil is arranged in the annular oil cavity 401, and the annular oil cavity 401 is connected with a heat exchanger 7 for cooling the buffer oil. In this embodiment, the annular oil chamber 401 is in communication with the heat exchanger 7 through two pipes, wherein one pipe is opposite to one of the rotors 402 at the interface of the annular oil chamber 401, and the other pipe is opposite to the mixing area between the two rotors 402 at the interface of the annular oil chamber 401. The buffer oil forms an inlet-outlet pressure difference in the movement process, the buffer oil circularly flows, and the generated heat is taken away by the heat exchange system. In the process of braking and retarding, the two rotors 402 are driven to rotate by the power transmitted by the two non-driven axles 1 respectively, so that the buffer oil in the annular oil cavity 401 generates centrifugal force, the centrifugal force forces the buffer oil to impact each other between the two rotors 402, so that resistance torque is formed, the mutual rotation of the two rotors 402 is blocked, and the kinetic energy is consumed by the friction of the buffer oil, so that the two non-driven axles 1 can be braked at the same time in a retarding manner. In the invention, the hydrodynamic coupling is arranged between the two non-driving axles 1, so that the two rotors 402 have opposite rotating directions and can generate larger braking torque, thereby greatly improving the effect of retarding braking by utilizing the interaction between the two non-driving axles 1. The central shafts 403 of the two rotors 402 are respectively connected with the corresponding speed-increasing torque-reducing mechanisms 5, and the two speed-increasing torque-reducing mechanisms 5 are respectively connected with the corresponding input shafts 302 through the clutch mechanisms 6.

The speed-increasing torque-reducing mechanism 5 increases the rotating speed of the non-driving axle 1 of the trailer for driving the double rotors 402 at the same rotating speed, thereby further increasing the braking torque, improving the retarding braking effect, and prolonging the service life and the stability of the trailer.
When the cargo trailer descends a long slope, a driver turns on a switch of the electromagnetic coil 605, the electromagnetic coil 605 is electrified to generate magnetic force, under the action of the electromagnetic force, a spring leaf of the armature 601 is deformed, a driving disc and a driven disc group in a friction pair are attracted with the armature 601 together, the clutch is in an engaged state, the input shaft 302 is driven to rotate by the power of the non-driving axle 1, then the output shaft 604 of the clutch mechanism 6 is driven to rotate, the planet carrier 502 is driven to rotate by the output shaft 604, the planet wheel 503 on the planet carrier 502 drives the sun wheel 501 to rotate, finally, the rotor 402 of the double-rotor type hydraulic coupler 4 is driven to rotate by the sun wheel 501, the annular oil cavity 401 of the double-rotor type hydraulic coupler 4 is filled with buffer oil, and the two rotors 402 stir oil in the working cavity to generate centrifugal force. Centrifugal force forces oil to impact each other between the two rotors 402, kinetic energy is consumed by friction of working fluid, so that resistance moment is formed to block the mutual rotation of the two rotors 402, mechanical energy is finally converted into heat energy, and the heat energy is dissipated through the heat exchanger 7, so that the slow braking effect is realized. When the cargo trailer does not need to be braked slowly, the electromagnetic coil 605 is powered off, the magnetic force disappears, the armature 601 rebounds under the action of the elastic force of the spring piece, the clutch mechanism 6 is in a separated state, and the hydraulic retarder does not work, so that the power consumption of the trailer is not influenced.
