Description
Technical Field
The invention relates to a vehicle axle and a trailer axle structure, in particular to a vehicle axle structure with a hydraulic retarder.
Background
With the rapid development of ground transportation systems and highway networks, trailers or semi-trailers are becoming faster and larger. Traffic accidents of the trailers are often caused by poor braking performance, so that the braking safety performance of the trailers gets more and more attention, and how to improve the braking performance of the trailers becomes an urgent problem to be solved.
The trailer and the tractor mostly adopt standard air brake, the generation and the removal of air pressure in a pipeline of a standard air brake system are slow, and the action lag time is long (0.3-0.9 s); the working pressure of the pipeline is low (generally 0.5-0.7 mp)a) Therefore, a series of problems of low braking efficiency, slow braking response, long braking fade time and the like exist generally in the trailer braking system, and the braking response time of the trailer is lower than that of the tractor, and the braking strength of the trailer is lower than that of the tractor due to the low braking efficiency of the trailer, so that the folding and the tail flicking phenomena frequently occur in the braking process, and the driving direction is suddenly changed due to the mutual collision between the tractor and the semitrailer. The brake system can avoid the brake failure of the vehicle when the temperature of the vehicle brake system is too high due to the frequent use and braking of the vehicle when the vehicle descends a slope, and traffic accidents are caused. This phenomenon often results in the loss of personnel and property through disastrous traffic accidents.
The axle of the hydraulic retarder can be used for heavy truck commercial vehicles, passenger cars, traveling buses, school buses, dangerous goods freight vehicles, special engineering vehicles, various military equipment vehicles and the like, can reduce the braking by 80-90%, can reduce the frequency of 90% of stepping on the brake, the clutch and the gearbox for engaging gears, and can reduce 90% of traffic accidents caused by brake failure (10 more than ten thousand people die each year, 20 more than ten thousand people and hundreds of millions of people's life and property losses caused by the current traffic accidents). The hydraulic retarder axle is an intelligent whole machine product integrating machinery, electricity, gas, oil, liquid, a controller, (ECU) control wire harnesses, an operating handle, various high-sensitivity sensors, a proportional valve, a one-way valve, a heat exchanger and the like into a whole, can be jointly braked together with engine braking, exhaust braking and the like, does not need a water tank water sprayer arranged on a frame by a soil method to reduce the temperature of a braking system, and at present, a plurality of domestic documents prohibit an automobile from using the water tank water sprayer for braking, and road traffic accidents are frequent because the automobile uses the water tank water sprayer for braking to cause the road surface to be slippery and icy.
The hydrodynamic retarder axle hand-dial switch is arranged on the right side of a steering wheel and is divided into 6 gears: the 0 gear is closed, the 1 gear is a constant speed gear, the downhill is called a cruise gear and a constant speed gear (if the gearbox is hung at the 9 gear, the constant speed is 50 kilometers), the 2 gear is 25% of the maximum retarding torque, the 3 gear is 50% of the maximum retarding torque, the 4 gear is 75% of the maximum retarding torque, and the 5 gear is 100% of the maximum retarding torque, namely the hydraulic retarder enables a rotor to be connected with a differential through shaft to decelerate by working oil in a reverse direction, and the faster the vehicle speed is more than 40-60 kilometers, the better the effect is! The hydraulic retarder axle auxiliary can also independently undertake deceleration braking, and the gear shifting is convenient! If the emergency situation in the front occurs, the finger on the right side of the steering wheel is slightly dialed, the steering wheel can be directly dialed from the gear 1 or the gear two to the gear 5 for 100 percent of deceleration, and the hand can also be used for simultaneously stepping on the brake to implement combined braking! The traffic accident can be avoided in the shortest distance.
The hydraulic retarder can bear most of braking load when an automobile runs, so that the temperature rise of the wheel brake is greatly reduced to ensure that the wheel brake is in a good working state, and further potential safety hazards such as failure of the vehicle brake, failure of a traditional brake, tire burst and the like are relieved or avoided. The retarder can provide strong braking torque in a quite wide rotating speed range, low-speed performance is good, when the speed of the vehicle is 20 kilometers per hour, the retarder can also provide retarding braking, and when the speed of the vehicle reaches 40 kilometers per hour, the retarder can achieve the maximum braking torque.
