Abstract
A double parallel hydraulic braking device of farm tricycle consists of a braking pedal (6), a corresponding transmission part (7), a double pipe braking chief-pump (4), a rear wheel bidirectional balanced brake (1), an oil cup (5) and a corresponding pipe (3). The device comprises two parallel braking circuits, and the two braking cylinders connected with each circuit are also parallel to compose a matrix and double parallel braking system, the reliability of whole machine is greatly improved, the device has the advantages of compact structure, low manufacture cost and convenient operation.
Description
" technical field " the utility model relates to Vehicular brake device, particularly belongs to a kind of hydraulic brake system at agricultural tricycle.
" background technology " is along with the develop rapidly of rural economy, quite universal with agri-vehicle as transportation means, particularly simple and practical agricultural tricycle is very big in the occupancy volume in rural area, and it has brought convenience for people's live and work, but the generation of traffic accident also increases thereupon to some extent.The reason that analysis causes a traffic accident, brake system failure are one of main factors.Be directed to this, people have invented some emergency braking apparatus, for example adopt the additional chock formula emergency braking of mechanical structure or the lifter flap descended to reach the purpose of forced brake with pavement friction, because these structures lack practicality so be difficult to apply by master cock.No. 96204451.2 patents " farm vehicle double loop brake equipment " in first to file, a kind of double circuit hydraulic braking arrangement that is applicable to the farm vehicle that the speed of a motor vehicle is lower is disclosed, its principle is to set up a loop on the basis in a loop again, both independent operatings, a cover mechanism acts under the malfunctioning situation therein, can continue to use another set of mechanism, thereby improve the coverage ratio of drag.But owing to establish one's own system in above-mentioned two loops, related components repeats to arrange, complex structure, and cost of manufacture height, and operation inconvenience can not really play the effect of emergency brake.
" summary of the invention " the purpose of this utility model promptly is to overcome above-mentioned defective, and a kind of compact conformation is provided, and cost of manufacture is low, and is easy to operate, is beneficial to the agricultural tricycle two-in-parallel hydraulic brake system of emergency brake.
The utility model is achieved through the following technical solutions: the utility model is made up of brake pedal (6) and corresponding Transmission (7), master brake cylinder (4), brake cylinder (2), rear wheel brake (1), lubricating cup (5) and corresponding pipeline (3); It is characterized in that said master brake cylinder (4) is the dual line braking master cylinder, two tubing interfaces of A, B are arranged on it, connect a, b two cover loops respectively; Totally two of said rear wheeies brake (1), about being installed in respectively on two trailing wheels, be bidirectional balanced formula drg, arrange a1, b1 and a2, b2 brake cylinder on it respectively, a1, a2 brake cylinder and b1, b2 brake cylinder are connected with two loops of a, b respectively.
Because brake system of the present utility model comprises two brake circuits in parallel, two brake circuits are relation in parallel, two brake cylinders of bonded assembly also are relations in parallel on each loop, thereby constitute matrix form, two-in-parallel brake system, therefore global reliability of the present utility model is greatly improved.Because two loops shared are overlapped master brake cylinder, brake pedal and corresponding Transmission, therefore had compact conformation, cost of manufacture is low, easy to operate good effect again.
" description of drawings " accompanying drawing part further discloses technical characterictic of the present utility model:
Accompanying drawing is the utility model hydraulic brake system principle of work scheme drawing.
" specific embodiment " as shown in the figure, the utility model by brake pedal (6) and corresponding Transmission (7), master brake cylinder (4), brake cylinder (2), rear wheel brake (1), lubricating cup (5) and accordingly pipeline (3) form.Master brake cylinder (4) is the dual line braking master cylinder, and two tubing interfaces of A, B are arranged, and connects a, b two cover loops respectively, and the repairing in two cover loops is realized by two separate lubricating cups (5).
About a cover bidirectional balanced formula drg (1) is set, totally two respectively on two trailing wheels.Arrange a1, b1 and a2, b2 brake cylinder on the rear wheel brake respectively, a1, a2 brake cylinder and b1, b2 brake cylinder are connected with two loops of a, b respectively.
Claims (2)
1, a kind of agricultural tricycle two-in-parallel hydraulic brake system is made up of brake pedal (6) and corresponding Transmission (7), master brake cylinder (4), brake cylinder (2), rear wheel brake (1), lubricating cup (5) and corresponding pipeline (3); It is characterized in that said master brake cylinder (4) is the dual line braking master cylinder, two tubing interfaces of A, B are arranged on it, connect a, b two cover loops respectively; Totally two of said rear wheeies brake (1), about being installed in respectively on two trailing wheels, be bidirectional balanced formula drg, arrange a1, b1 and a2, b2 brake cylinder on it respectively, a1, a2 brake cylinder and b1, b2 brake cylinder are connected with two loops of a, b respectively.
2, agricultural tricycle two-in-parallel hydraulic brake system according to claim 1, its feature are that also the repairing in said a, b two cover loops is realized by two separate lubricating cups (5).
