The principle of work of TRC is still similar to TCS with ASR, and just each manufacturer has any different on the call of technology.TRC can suppress vehicle in the idle running of wet-skid road surface starting with drive wheel when accelerating, when starting to walk or accelerate, if detect drive wheel idle running, the braking oil pressure of drive wheel and the Power output of driving engine will be controlled, guarantee the safety of best starting, acceleration, straightaway and turning.
● nonskid tire
Current each giant tyre manufacturer all develops steel-studded tire, and cardinal principle is by the change of tread contour and on tyre surface, arranges the friction force that some attachments increase tire and ground, thus prevents tyre skidding.
But the problem of wheel sideslip when these systems just solve brake, or can only use under particular circumstances, and with high costs, design and installation service routine is many, troublesome poeration, and not from reducing braking distance in fact.And with regard to nonskid tire, practical popular style is lower, can only be use in certain circumstances, need smaller resistance, so can not equip as emergency facility always when highway up train at ordinary times.
Summary of the invention
It is simple that the utility model provides a kind of structure, meet an urgent need anti-skid device actuating unit in economic and practical automobile-used snow sky, solving prior art existence does not have substance to shorten the problem of braking distance, the utility model utilizes slipmat to produce resistance, vehicle can be produced when emergency brake than originally much bigger resistance, and do not hinder vehicle to require slight drag in motion.So greatly solve the generation of snow sky accident.
Technical solutions of the utility model accompanying drawings is as follows: a kind of automobile-used snow sky anti-skid device actuating unit, this actuating unit comprises two trapezoidal supportings 1, stepping motor 2, two connecting rods 4, cylinder 5, spool spring 7 and spool center shafts 8, and wherein said two trapezoidal supportings 1 are arranged in parallel and are fixed on engine mounting; Described stepping motor 2 is bolted on above two trapezoidal supportings 1; The output shaft 3 of described stepping motor 2 is connected by rectangular spline with the one end of two connecting rods 4 be arranged in parallel; Described cylinder 5 is connected by rectangular spline with the end of two connecting rods 4; Described spool spring 7 is enclosed within spool center shaft 8; Described spool center shaft 8 is fixed with bolts on vehicle frame; Slipmat 6 in automobile-used snow sky anti-skid device is wrapped on spool spring 7; The outermost end of slipmat 6 is screwed with cylinder 5 and is connected.
The beneficial effects of the utility model are:
1, be swift in response.Adopt such device, can rapid reaction.When driver sends emergency braking, driving stepper motor link rotatable, the lower end of bar is connected with slipmat, pulls out slipmat by bar, makes slipmat move under wheel, by pressure wheel on top.
2, reliable.After driver sends emergency brake signal, driving stepper motor pinion rotation, gear driven link rotatable, the lower end of bar is connected with slipmat, pull out slipmat by bar, it is less that mechanical device is subject to extraneous interference, and slipmat can enter under tire fast and accurately.
3, the resistance produced is large.The materials and structures of friction force is strengthened in design due to slipmat, so friction force when replacing tire to produce producing between the slipmat energy of friction force and ground super tyre braking system far away, can car be made more rapidly to brake.
Car sideslip when 4, can prevent from braking.Consider the original intention of ABS system during slipmat design, so side slipmat being close to wheel is designed to the very little material of friction force, make rear wheel be unlikely to locking.And the conclusion of the side of slipmat and earth surface experimentally gained carrys out the arrangement form of design arrangement pin, car is made to be unlikely to produce the situation of sideslip in the anxious stopping time.5, can recycle, with low cost, popularization is high.Also cooperatively interact slipmat recovery, to be used for next braking by the regenerative apparatus of reversing and slipmat after emergency braking.Achieve recycled for multiple times, can also material be saved while reducing costs, realize the target of the green industry of development.Whole device is very low compared to the cost of the emergency stop device of other high-end vehicles, is conducive on a large scale universal, and structure is simple and can be more reliable, and fundamentally shorten braking distance, achieve snow sky emergency braking, effect is very good.
