Description
Technical field
The present invention relates to large-scale load-carrying vehicle brake control art, be specifically related to a kind of large-scale load-carrying vehicle lower long slope assisted deceleration system.
Background technology
At present, the brake system of existing vehicle is substantially friction type brake, substantially the kinetic energy of vehicle is converted to frictional heat energy.The most large-scale load-carrying vehicle for a long time the most on slope and long and time the mountain highway of apprentice travels, brake rim or brake disc cause heat to increase sharply because of frictional damping, but poor radiation, and heat fading problem can have a strong impact on braking effect, causes many vehicle accidents.
Heat fading is to produce substantial amounts of heat owing to rubbing between brake block and brake drum and cannot get rid of in time and constantly accumulate, when temperature exceedes certain numerical value, coefficient of friction between brake block and brake drum will drastically decline, thus causes friction effect to weaken, the phenomenon that brake speed slows down.
In order to avoid heat fading problem, at present frequently with the following two kinds solution:
On the one hand cheap water tank fountain cooling method can be used.Such as, many drivers are had to be mounted with a kind of device making brake drip the most voluntarily, this device mode manually, during vehicle descending, open water valve to lower the temperature to brake rim jetting through pipeline by the cold water of high level water tank, avoid the heat energy scaling loss brake block now produced because of braking, cause brake failure, under use hands shutoff valve again behind complete slope.But, existence of manually dripping disperses the attention of driver, forgets valve opening and forget to close the problems such as valve.And waste limited water-retention.And, fountain heat sink is relatively big due to water tank weight, and from hundreds of kilogram to a metric ton, the load-carrying of automobile increased, thus causes oil consumption also can strengthen, and needs in transit constantly to supplement water in water tank, increases the expense of transport；Fountain device is fixed on wheel outer end due to outlet, causes fin to there is internal-external temperature difference so that brake block ruptures due to unbalanced stress；Fountain heat sink in the winter time when be susceptible to freezeout in atmosphere owing to elongated water pipe exposes, it is impossible to be brake drum trickle in time, cause radiating effect to decline, initiation vehicle accident.And unnecessary trickle drops onto road surface, cause icy on road, skid resistance compromises, easily bring potential safety hazard to rear car.
On the other hand can alleviate the brake load of brake block and brake drum in the way of using retarder or EVB electromotor, thus improve braking effect.Retarder or the mode of EVB electromotor, owing to structure is complicated.Maintenance difficult, and cost is higher, also use in the heat radiation of truck at present is not the most universal.
Patent CN 201833997U discloses a kind of automatic automobile brake drum circulatory cooling system.This system uses temperature sensor senses temperature information, can select to automatically control or Non-follow control, when be in automatically control time by the brake signal of controller Real-time Collection automobile, judge in conjunction with temperature signal, decide whether that feed pump and fan are powered, thus realize automatically controlling of braking automobile；Non-follow control is then the power supply that water pump and fan are connected in the judgement according to driver self.But the mode that this technology still uses fountain is lowered the temperature, it is impossible to water route frozen problem in water pipe during solution low temperature, and add signal control portion when brake, easily impaired in transportation, and overhaul difficulty.
Summary of the invention
It is an object of the invention to provide a kind of large-scale load-carrying vehicle lower long slope assisted deceleration system, this device can with brake system with the use of, in the long-time braking procedure of vehicle, the mode manually or automatically controlling clutch makes vehicle braking energy be converted to spring potential energy, thus consume vehicle energy to a great extent, significantly alleviate the frictional heat energy that brake system produces when long-time high pressure rubs, effectively overcome heat fading problem.
For achieving the above object, adopt the following technical scheme that a kind of large-scale load-carrying vehicle lower long slope assisted deceleration system, by bearing, bent axle is installed on vehicle chassis, the axle center of bent axle is parallel with axletree, and the one or both ends of bent axle are connected by clutch by drive mechanism and axletree and are provided with the switch controlling clutch；Being mounted with energy dissipating spring on bent axle, the end of energy dissipating spring is connected on vehicle chassis.
The one or both ends of described bent axle are provided with one-way driver；Described one-way driver includes that driving disc spacing pressing and clutch plate, driving disc spacing pressing are connected with drive mechanism outfan, and clutch plate is connected with bent axle；Being provided with fixing helical teeth or elastic helical teeth on driving disc spacing pressing and clutch plate, or fixing helical teeth and elastic helical teeth combine, holding driving disc spacing pressing can drive clutch plate acting but clutch plate can not drive driving disc spacing pressing to do work.
The two ends of described energy dissipating spring are connected on spring base one and spring base two, and spring base one is hinged on bent axle, and spring base two is hinged on spring base supporter.Spring base one and spring base two pass through bearing hinge connection respectively on bent axle and spring base supporter.
Beneficial effect: the angle that the present invention changes from energy is set about, is converted to spring potential energy by the vehicle energy of brake process and is automatically releasable.Utilize clutch mode manually or automatically to control, existing brake system can be coordinated to use, the brake applications of existing brake system can be alleviated largely, it is ensured that car braking safety, improve brake system service life.The present invention additionally uses the mode of one-way driver, it is ensured that only vehicle energy is converted to potential energy, but can not be kinetic energy by potential energy converting and energy.Present configuration is reasonable in design, it is possible to using with the collocation of existing vehicle, using effect is the best.
