Abstract

The utility model relates to a non-skid brake for a vehicle which is matched with a vehicle tyre, and the utility model is the improvement of a '97219322.7' patent application. The rotary joint of the utility model is installed on the circle center part of an upper disc, and the rotary joint is communicated with an oil pipe, the lower part of a tooth nail is provided with a hydraulic oil cylinder which is communicated with the rotary joint, and reset springs are installed at both sides of the hydraulic oil cylinder. When the vehicle traveling on a snow and ice road surface to brake, oil enters in the hydraulic oil cylinder to press the tooth nail to extend out, and the tooth nail is pricked in the snow to have synchronous brake and skid prevention with the brake. The utility model has the advantages of reasonable structural design, flexible brake, etc. The utility model is an ideal anti-skid device for the vehicle.

Description

The vehicle limited slip drg

The utility model relates to a kind of vehicle limited slip drg that uses with motor tire, belongs to brake device for car.

At present, the vehicle that travels in the world of ice and snow, mostly the suit crawler belt is used for anti-skidding on the tire of automobile, although reduced the safety hazard of vehicle ' in the snow sky, but also there are many unsatisfactory parts, the one, it has just strengthened friction drag, do not penetrate the snow face and guarantee the function of car brakeing, the 2nd, the trouble heaviness is installed, designing in person for this reason and having invented " vehicle limited slip drg " number of patent application is the deficiency that " 97219322.7 " this invention has overcome skid track, its unsatisfactory part is, and is flexible and convenient to use at cement pavement, is not suitable for using at pitchy road.

The purpose of this utility model is to overcome the deficiency of patent application " 97219322.7 " and provides a kind of hydraulic ram to be positioned at both sides, finger bottom retracing spring is housed, oil circuit, vapour road by vehicle itself penetrate ice and snow road, the vehicle limited slip drg that can travel on the cement road and can travel with the finger ejection on pitchy road.

The purpose of this utility model is achieved in that it comprises the chassis, goes up dish, oil pipe, finger, last dish is buckled in bolted connection on the chassis, equidistantly be provided with finger on the excircle of last dish, there is oil main line the middle and lower part, and oil main line is communicated with oil expeller, and its structural feature is, the position, the center of circle that swivel joint is fixedly mounted on dish is communicated with oil pipe, hydraulic ram is equipped with in the bottom of finger, and hydraulic ram is communicated with swivel joint, and retracing spring is installed in the both sides of hydraulic ram.

The purpose of this utility model can also realize that finger is installed in the guide rail by following technical measures, and guide rail is fixedly mounted on the excircle of deep bid, and finger is a nylon staple, the steel finger.

Compared to existing technology, the utlity model has following advantage:

1, go up uniform finger on the excircle that coils, when ice and snow road travelled, finger ejected under the effect of hydraulic ram, penetrates ice and snow road, and braking is timely, and the size appropriateness is not destroyed the road surface;

2, as ice and snow when thick, the may command finger is worked for a long time outside, when missing the bus, can help vehicle in time to escape danger;

3, scientific structure design is reasonable, and this device is provided with two cover fingers, one cover and is used for the nylon finger that asphalt surface uses, and a cover is used for the steel finger that cement pavement uses, and meets the regulation of traffic department fully.Other establishes swivel joint, good seal performance.

4, Applicable scope is extensive, can be used for ice-snow field, desert, earth ground.

The explanation of accompanying drawing drawing:

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A face cutaway view of Fig. 1.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

The utility model is the brake equipment that is used with motor tire, is to " 972l9322.7 " the improvement of patent application.Constitute by chassis (9), last dish (1), oil circuit or vapour road.Chassis (9) is fixedly mounted on the keel of motor tire, and last dish (1) is fixed on the chassis (9) with screw (14).On the excircle of last dish (1) finger (4) guide rail (5) is installed, the top of finger (4) is Shape.Finger of the present utility model (4) is two covers, a cover nylon finger one cover steel finger.The nylon finger is used for asphalt surface, and the steel finger is used for the cement flooring.This design meets the road management maintenance regulation of traffic department fully.Hydraulic ram (3) or cylinder are installed below the finger (4), and hydraulic ram (3) is fixing with nipple bent piece (13).Finger (4) is loaded in the guide rail (5).Guide rail (5) is fixedly mounted on the excircle of dish, and cylinder is the liberation automotive use.The both sides of hydraulic ram (3) are equipped with spring (6), and spring (6) is enclosed within on the pilot bar, and pilot bar is fixed on the both sides of hydraulic ram.The circle centre position of worker's dish (1) is equipped with swivel joint (8), bearing, and swivel joint (8) is fixing by adaptor union (11) packing ring (10), is communicated with by connection pipe (12) with hydraulic ram (3) to be connected with oil main line.Oil pipe of the present utility model is the below that oil main line, branch oil main line are positioned at dish (1) circle centre position, and oil main line is communicated with oil expeller (7), and each oil expeller (7) is communicated with hydraulic ram (3) respectively.The vapour road that structure is set is identical with oil circuit.

Working process of the present utility model will be gone up dish (1) and be buckled on the chassis (9), connect as one with screw with chassis (9), with big screw rod will go up dish (1), chassis (9) are fixedly connected on the keel of motor tire (15).When brake was travelled on the snow road, oil entered each oil expeller (7) from oil main line, after oil enters hydraulic ram (3), finger (4) in the guide rail (5) is ejected, stretch out on the excircle of last dish, snow is grabbed at the top of finger (4), penetrates behind the ice and snow road and the synchronous non-skid braking of brake.Behind the vehicle launch, spring (6) resets, and retracts finger (4), makes finger (4) get back to the original place.

Claims
